Galaxy Tab unbricking service - Galaxy Tab General

Stumbled upon this a bit ago, a company called Mobile Tech is offering an "unbricking" service on all versions of the Galaxy Tab. At the time of this writing they charge $50. I have not used this service, am not in any affiliated with this company and cannot vouch for their work, so beware. Just thought someone out there might use this when other options aren't available.
They have a nifty video up on youtube showing how they do it:

it will be a good help for those who brick their tab because they ain't follow the steps .. thanks for sharing this out

I can actually vouch third party for this service. Have had two friends use it and the device was returned within a few days. If I'm not mistaken, the guy lives in the southern US, but can arrange international he says.

This is cool, but I would recommend trying to go through Samsung first if you are still under warranty. I screwed up my primary bootloader and contacted them. They took care of shipping costs, fixed it up, and sent it back in about a week and a half. If Samsung hadn't fixed it I would defiantly have payed the $50 here though.

WOW, that seems like a lot of work for $50.
Thanks for the info, should I ever screw something up its nice to know there are people out there who can clean up my mess!

Hi spacemoose1
Thanks for link and as always, thanks for honeycomb port. I would like to ascertain the definition of BRICK? with your help, if I may.
(disclaimer: pls forgive my wrong terms or exagerated explanation, but most importantly, pls correct me if I'm wrong)
BRICKed = software total lost, must use JTAG to force revive it, Samsung has it, or buy from web supplier around 300 USD ??? 500 USD ???
JTAG is a device to push software into all newly borned IC. I.E. when factory make IC, it's empty software inside, hence has a special device to push voltage into all sections of the IC, then force the code in.
Another term is ???CRASH??? or ???HANG???, (I don't know) anyway is not BRICKed, hence a reflash can recover it.
Samsung uses proprietary method a lot, not follow conventional, make usb driver very complex. USB driver install EXE around 15MB to 28MB depends on version, ALL work the same.
but, when the device = sgt7 in different state/condition, the driver must RE-ESTABLISH again, or else cannot work.
I.E.
state 1 = "OPERATIONAL"device in android operation, normal use, surf web, phone call etc
state 2 = "SLEEP" device powered off, show battery big icon charging when powered by charger
state 3 = RECOVERY mode
state 4 = DOWNLOAD mode - this is one of the way to FORCE flash to recover, as long as bootloader and something still intact
state 5 = PHONE-!-PC mode
stage 6 = "COMA" device powered off, NO show of battery big icon, even when charger supplied. Don't panic, let it charge fully 4 hours from 2 amperes supply, 10 hours from PC 500mA. It will start again !!!. Battery big icon will appear around 30% battery charged, I know because that's what I saw. I didn't check when it's in 10% or 20%. The 1st time I check was already 30% up from no-boot or no respone.
User need to plug device into PC during each of the state above at least once, in order for various flashing functions to work.
i.e. when it's a newly arrived device, usually install the usb driver 1st, with device state in android OS running properly, then plug in to USB and see "new device detected" installing, pls wait. Finished.
But when flashing via Odin using state 4 = DOWNLOAD mode, user may experience no connection, no COM3 or something. Because device must be unplugged in USB, power-up in state 4 = DOWNLOAD mode, plug in USB, "new device detected" installing = RE-ESTABLISH, done. UNPLUG USB, replug in usb, then COM3 appears FLASH will be succesfull.
same goes for other state.
p.s. many users reported BRICKed but then recovered WITHOUT JTAG is misleading beginners, hence should rename the term to ???CRASH??? or ???HANG???. although some previously use "SEMI-brick", which is acceptable.
stage 3 = ClockWorkMod flashing (super convenient, especially on the move without PC)
stage 4 = Odin / Heimdall both works (still convenient and easy )
stage 5 = Odin / Heimdall both works (still convenient and easy )
???CRASH??? or ???HANG??? or "SEMI-brick" is usually SUCCESFULLY recovered via restock+PIT
(final disclaimer, incase above is correct and help and is copied, pls correct whatever mistakes found, feel free.)

Yeah, warranty repair is always a better choice. But sometimes you've already voided the warranty, lol.

I guess, if u change factory installed rom/kernel warranty gonna be history
thanx for the post ... it might gonna be the last resort...

I pretty much agree, but I might refine:
BRICK= Unit does not power up, visibly charge, reach a boot-screen of any kind including a service or "download" screen. A device in this state requires service from the manufacturer or an individual equipped with the proper tools. There is no other way to recover a device in this state.
SOFT-BRICK= Unit powers up, reaches a "download" or service screen, visibly charges but does not boot into an OS. Crashing, hanging etc. all apply here. It is easy to recover a device from this state so long as one has access to a firmware that was designed for the device and the ability to flash said firmware.
SEMI-BRICK= See soft-brick above
JTAG= Provides access to system hardware by applying the correct voltage to the correct pins in order to push software via an external program.
In regards to the usb drivers, there are only actually 4 states
1. Active userspace
2. Serial gadget mode
3. Recovery
4. USB storage mode
And there is a separate driver for each of these (except recovery) in the Samsung driver package that should install automatically when the device is plugged in during normal use on a stock rom, or with the installation package available on the web.
The rest of it you've got pretty much correct.

Money seems right, but the amount of work that guy has to go thru is amazing, so much to tare it apart, and reassemble. Then again when it is put back toether, he checks it, what if it did not take the fix... all over again.

Hardbricked Tab Save by Mobile Tech
I hardbricked my galaxy tab bought in Cambodia. My little brother open the tab trying to take the battery off and put it back on, thus void the warranty, found him on the Samsung vibrant forum, sent the tab to him got it back good as new. This person is professional, honest and good communication with his customers, you'll be happy with his work, if he can't fix it you get your money back (minus shipping and diagnosis)...Glad he is arround to help...

You should post this in Q/A thread on its own as its very helpful and maybe it will stop the 1% of people saying help my phone is bricked comments ... the other 99% don't read anyway otherwise they would discover their phone isn't bricked and if they read properly it would not have gotten to the state in the first place .. and no I never posted something like that myself >:¬}
but well done on this..

Nice find. For that amount of effort disassembling, and reviving, $50 is a very realistic price. I'll keep these guys in mind if I run into issues with my tab.

$50 for that much work is an absolute bargain! I wish I didn't live in a country where you get charged $200/hr for someone to pick their nose.

It's actually not that much more difficult than popping an OS install CD into a hosed computer and pressing 3 keys to let it run through the installation after flashing a corrupt motherboard BIOS. Yes, it takes familiarity with the software and hardware, but it's by no means a feat that requires a special skillset.
Granted, few people have JTAG stuff handy, so $50 is definitely worth it if you've hosed your device, but don't make it sound like he's sweating and coding the bootloader by hand, strenuously manipulating micro tools to disassemble the tablet and flipping DIP switches to restore the bootloader. You spend 5 minutes taking apart the tablet, you attach the JTAG cable, run the supplied software on your computer, and sit there recording the screen with your video recorder while the progressbar moves from 0 to 100.
Again, it's worth $50 simply because not everyone and their mother has JTAG hardware sitting around, but by no means is it hard. It's the same reason I can get away with charging $100 to clean viruses off of a computer. People either don't have the tools or don't know how to use them. That being said, I don't know a damn thing about using JTAG to restore a corrupt bootloader, nor do I have the right hardware, so I'd pay $50 if I were ever in the situation.
Edit: And yes, $100 for a virus clean is a lot, but people generally change their mind when I explain to them why they got viruses, as well as installing proper antivirus software and then instructing them on how to avoid infection in the future. I rarely get repeat business from the same customer but I get A LOT of referrals ;p They're happy paying that much when the person educates them instead of cleaning, not installing/explaining, then having to bring the computer in again two weeks later for another wallet-gouge, which most other computer 'repair people' gladly do over and over.

Everything in this world is rinse and repeat... The money comes from time spent learning to use the hardware properly, micro soldering skills (which isn't easy, no matter who you are), confidence enough to offer it as a service, not to mention the couple hundred bucks for the jtag software and hardware.
Now, the fact that if you have your device in a bricked state you likely voided the warranty, it's a 600 dollar brick if your samsung tech recognized it... 50 bucks is a steal to not deal with samsung anyway.
Try to be less pompous next time oh savoir of the hundred bone virus... Your poop stinks too, promise.

I've got to call you out on this one. Mis-connecting or shorting any wires will lead to a damaged PCB and an un-resurrectable TAB. I'm also a Systems Admin for a living so I understand where you are coming from. You must realize that I solder at levels of .1mm in spacing on the Captivate, Vibrant and Nexus S. Electrical engineers and technicians have first hand talked with me about the difficulty of doing this and is NOT something that anyone can do. You'd think twice when you burn up a phone or two valued at $500 a pop trying to JTAG them. There is more skill involved than you would think. Not to mention the liability when dis-assembling the device. JTAG software is decent but it's not fully automated. There are TCK frequencies, RTCK frequencies different PBL partition sizes, full dcc loader read/writes and the requirement of EXACT voltage from an external power supply that are needed in MANY cases. Plus, there is little to no support when fixing a device. This means that if you can't figure it out, nobody else is going to for you. I'm not trying to brag but yet point out that this isn't like plugging in your phone for an ODIN flash. I've taken hundreds of hours of time and 1000's of dollars to create what I feel is the most trusted JTAG authority online ANYWHERE. I greatly appreciate having the opportunity to help the community and enthusiasts in this community. If this was as easy as you are claiming, you could get JTAG hardware and a manual at Best Buy. I have to say you put it best when you said you don't know anything about JTAG... Ok end of rant I was just a bit bothered by your post.
Ok with that being said, thanks for the personal testimonies and compliments. I will be here whenever anyone needs JTAG assistance in the future or around the forums to help answer Q&A when it doesn't require JTAG. Here is a Nexus S promo to realize how tiny some of these things are

i would love to learn more on how to do stuff like this if i had moneyz. the .1mm ext.
not just for android but to make my own ish.
thanks for the awsome videos.

Thanks for the link, hope I won't need it ;-)

Real TRUE Brick this time

[PROBLEM SOLVED]
Ive been flashing back and forth to different builds trying which is better. I made sure I took the cautions not to flash builds that would brick my phone. There were 4 times that I soft bricked my phone but I was able to revive it. However, my little game has come to an end with this last one. The fault was this guide: http://forum.xda-developers.com/showthread.php?t=817186.
Little did I know, by doing a repartition and not loading anything to the NAND resulted in the bootloader not being installed. (Devices like this should have a ROM programmed to recover from these errors, think Gigabyte) Upon reset, the phone went out and didn't turn back on. ODIN reports success. Now the phone cannot turn back on, no matter what battery pull method I use, I get nothing on the screen. So much for fail-safe protocols Samsung has implemented, if there are even any. Poorly engineered!
EDIT:Thanks for all your suggestions guys. So yes this phone was definitely bricked beyond any software repair. I was going to JTAG it but I figured there MUST to be some hardware bootloader implemented. I went ahead and did the USB JIG and surprise, it booted from the hardware bootloader. I used ODIN to flash JFD and it works now. So my guess is samsung did implement a fail safe, which is the USB trick and forces the phone to boot from hardware. If that is true, this phone is brick proof, provided that all electronics still work.
EDIT 2: I am wrong about the bootloader being hardware. Some say it is flashable, so it is possible you can get a real TRUE brick and must need JTAG to revive it. Fortunately for me, I was able to use the USB JIG method to get it back up and running. Too bad, a new phone would've been nice.
Not poorly engineered, just poorly made user input.
Yes true, but samsung should have taken into account accidents like this will happen then they dont have control over who administers their update. People have bricked their phones by doing the factory update. When I design systems like these, I always make sure there is a fail safe backup that the user cannot modify. I am sure samsung has one and maybe they just dont let us access it.
I sometimes encounter the same error message but I never repartition. Luckily, i never clicked on it in Odin.
But you have to realize that most of those bricks are because people modified their phones from factory (ie. Voodoo and OCLF). Odin, a program used by internal Samsung engineers, was never meant for the public and shouldn't be used unless you know how to use it.
I agree, there should be an absolute fail safe if worse comes to worse, but the point I am making here is Samsung isn't wrong in this case.
When you violate warranties and experiment you tacitly accept responsibility for your actions. To not do so is not an act of rebellious ire...it is an act of denial.
Manufacturers do not, nor can not prepare for all scenarios because the possible number of scenario's to cover are legion. I don't see it as realistic especially for them to prepare for brick scenario's created by using a leaked internal engineering tool that the community has figured out largely through trial and error either. OTA and Mini Kies bricks they are responsible for, for obvious reasons, and Samsung and T-Mobile have taken responsibility for these scenarios because they are ones of their making.
XDA is not a place where people file warranty complaints (though some do complain). It is a place where people experiment, hack, and customize smartphones. Though some manufacturers do a better job than others at getting out of our way here (Samsung hasn't done so bad here relative to say Motorola), I don't think any of them particularly "care" about such community efforts in any meaningful sense. And why should they?
By modifying our devices aren't we quite clearly saying we're taking matters into our own hands? You have to balance your strong desire to tinker with the reality of where responsibilities lie.
These phones are some of the most difficult Android phones to brick. Anecdotally and statistically shown to be. Not impossible of course, but quite difficult. I feel for your bad experience but at least consider shouldering some of the blame.
Thank god i am too scared to use odin. The deepest i go is clockwork recovery, but good luck with your paperweight.
Too bad the SGS is so light, it wouldnt make a good paperweight, or even a brick.
but seriously, the warranty is there to protect users which this happens to, assuming it wasnt voided by hacking the phone. Are you asking samsung to take into account that you would hack the phone and provide a way back after you have a bad hack and probably make themselves liable by providing that way back in case it does not work properly?
I want to be clear that I am not blaming samsung for this but I thought samsung could have done a better job. Ill admit, this phone was the first phone that impressed me in years and as an engineer, I am hardly ever impressed; other engineers will get my point. I wish they had some soft of fail safe mechanism. For us who like to tweak things, I get we get what we deserve. But what about those who dont like to tweak and still brick their phones? i.e. those who use Kies Mini and still brick. I still have warranty on the phone and I'll try to take it up with Tmobile, hope they don know much about flashing. BTW, I tried using the other program but no go. All the drivers were installed, rebooted computer...nothing. I think it is because I have W7 64 and not 32?
Have you tried the jig method of getting into dl mode?

Keep on flashing, and eventually Odin will probably save your butt
Don't be scared of it, it works great. And it is safe to use.
========================================
I'm really sorry about your phone man, I didn't know that you had to NAND before re-partition, thank god I've never checked that but I might have in the future had you not shared this with us, so thanks a lot!
I guess your loss is everyone elses gain
No I havent tried the Jig method. The thread says that I need to have at least the samsung screen, so some kind of activity. This phone is just off, nothing comes on, no buttons, no screen...just dead. I think when I followed that guide, it told be to repartition and then reboot with the "PDA" field empty. So the phone rebooted when it finished formatting without installing anything. Now the NAND is at a "blank" state and I do not have any bootloader on there. Anyone know of a method to install a bootloader without the phone turning on?
I might be a little too far out of my element here but I think I found a guide to remove the sdcard and format it via pc one time when I was in a similar situation. I am at work currently and I also cannot remember if I have the link saved.
Maybe some phone expert in your city may help you to install the bootlaoder. I think it's called jtagging, I'm not sure though.

Just call Tmobile and tell then that you were upgrading to froyo 2.2 using Kies mini and it froze...
I had a black screen once. I was flashing in odin and knocked the cable loose. I think I had to remove the battery, open odin, plug the usb cable in, then install the battery and possibly hold a key down on the phone. I believe the download screen then came up. Otherwise the phone would not respond nor would any lights come on

Depending on which drivers you installed (and there seem to be quite a few floating around) you might need to disable Driver Signature Checking in 64bit Windows OS's if the drivers are not signed. The easiest way I've found to do this is with EasyBCD . Install it, run it, click Advanced Options and enable loading of unsigned drivers. Do this before loading a potentially unsigned driver and you're good to go.
Just a tip, and my lengthy diatribe on responsibility was more to stem the potential tide of trolling such a thread is likely to generate than dump on you. I know what it's like to brick things. I've been bricking stuff for 30 years lol.

To disable driver signing, you ONLY need to run a single command and then reboot. And this applies to both Windows 7 and Vista.
Also to the OP.
You say you have no bootloader, but can't find ANYWHERE in this thread that says you were attempting to flash a bootloader. In fact, you can **** up partitioning, and your bootloader is still in tact. Been there, done that.
Do this. Plug the phone in, and leave it charging for about 30 minutes. Pull the phone off, hold the volume buttons, and plug the phone into a computer. See what happens. I had a ****ty situation end up happening to me, that I couldn't get the phone on for about 30 minutes. I had already even called T-Mobile for a replacement.
Thanks for all your suggestions guys. So yes this phone was definitely bricked beyond any software repair. I was going to JTAG it but I figured there MUST to be some hardware bootloader implemented.

This "hardware" bootloader as you are calling it, is the exact bootloader that you can flash and TRULY brick your device. It is NOT a failsafe in the way in which you are referring. Please, please don't call it this. There are plenty of users on this forum that are clueless. The jig method, is a hardware jump point that Samsung has built in to allow you to get to download mode situations where the button method does not work.
As I mentioned earlier, you didn't flash a bootloader. Nor did you full on brick your device. Glad your device is back to normal now though.
my apologies then, it would be easier if samsung gave us the schematics, but that would never happen. So when we use odin to flash, we are not flashing the bootloader as well? Is the bootloader located on another ROM that is not easily accessible? I guess ROM would be the incorrect term since you stated you can "flash" the bootloader.

Acer Iconia bricked...Need help

Hello to all good guys in xda-developers forum.
This is my very first post and I really feel desperate and need your kind help.
New Acer iconia with stock firmware 3.2.1 was nicely running this morning until I tried to root the device.It was supposed to be very simple process and not to get into dirty complicated procedures but the gingerbreak.apk did not work as expected so I tried alternative methods.What I read in various forums was that the gingerbreak application is not able to root the new firmwares version so I tried to downgrade the firmware to 3.0.1.
Downloaded the Acer stock recovery firmware EUUs_SBK_Acer_A501_0.017.01_PA_ATT.exe and attempted to flash onto my tablet .I think I did all necessary pre-installation checks.The process started but it stopped on 10 percent for about 30 minutes without any progress.Only Acer logo was displayed and 'entering file downloading mode' at the top of the screen.
After long time no change I finally gave up and unplugged the device from the USB port and restarted but nothing works since then.
1. No vibration on Start
2. Black screen
3. No new USB device appear on my PC
4. No sign of any activity other then power button light
I guess the original firmware was wiped but the new firmware was not flashed...for whatever reason...perhaps the worst scenario.
I will really appreciate If anybody may give me advice how to fix it.
So it turns on but does not display anything? Have you tried to hold the power button and volume down button at the same to when you turn it on to try to get it into recovery. Also there is a little reset button on the side you can try to push.

tried all those thinks.All kind of tricks I could find on the net.The problem is that the device is not showing up in the device manager e.g not detected as USB device of an y kind....

Try this thread. Look about halfway down, and you'll see almost the exact thing you did, and how this guy got it going.

Basically you can run a search for APX in the main forum threads and find some other posts, but hopefully this will get you going.
I pulled this from the general forum (eventually), but you can also search the Q&A main forum page as well, and the dev forum.

Acer or the store did not brick it
i THINK If you mess with the rom on your tablet and... BRICK your device .. you should tough it out and fix yourself... Acer or the store is not responsible for this .But then you could also argue that if they had not locked the bootloader this type of bricking would not happen..
So i say go above and beyond to try to fix it from the help on here.. if that fails.. THEN Maybe exchange it.. Its wrong to brake something then expect someone else to foot the bill. Yes im to honest for my own good at times... Acer has also been known to repair .
If you bought a extra warranty all of the above in my book is out the window.. Make them replace it ..
GIGGLES..
Good luck on getting it repaired ..and be more careful next time..
Piece of cake to fix if you kept you USB serial number (from the downgrade tool)???
===== If you have your USB serial number ====================
1. Lets assume you know your USB serial number. If not, then you might be able to get it from your registry.
2. Download my flashing tool at http://forum.xda-developers.com/showpost.php?p=20680452&postcount=137
a. Open up the readme.pdf for the instructions on how to flash
3. KEEP your acer unplugged and run the program
4. The program will install the APX flash drivers and will tell you to plug in the USB. Ignore this step. It will not work. In the instructions skip steps 3, 8, 9, 10.
5. Eventually the flashing tool will timeout because you do NOT have the tablet connected. It will then display a message box telling you how to use a paperclip and the power button to get you into APX mode. THIS IS THE secret to getting the tool to flash your ACER. However, once you get it into APX mode you will need your USB serial number (without it, you are fubar).
a. Plug in the tablet to your computer with the USB and paperclip yourself to fastboot.
6. Now in step 11, enter your USB serial number
7. Now just follow the rest of the instructions.
====== NO USB Serial number ==========
If you do not have your USB serial number than you are going to be out of luck, unless you have ever connected the device to your computer. If you did, then your registry will have a history containing your serial number.
Google usbdeview tool and download it. This will show the serial number of any USB device you've connected to your computer.
===== No Serial number, never connected it, what to do ==========
If you have no serial number and cannot get it, then hopefully you can get to recovery mode (power & volume) and flash using a signed update.zip from ACER. Download one of the update.zip's and put it on your external SDCard and then boot to recovery.
=== Bricked and No serial number, never connected, and you fubar'ed the recovery image ===
If you never connected your table to the USB and your computer to get the USB serial number then you are NOT going to be able to flash it to fix it.
If you fubar'ed the recovery image then you won't be able to get into recovery to run the ACER update zip.
At this point, you can still get your tablet into APX fastboot mode using a paperclip and the power button. But I know of NO way to flash it without the USB serial number and I know noway to get the USB serial number from the APX driver. I've tried and looked at getting the serial number from just APX mode, but I cannot determine how to get it. Someone out there might know.
Hope this helps,
TD
Your CPUID can also be found in the uid.txt file in your cwm backup folder - /mnt/external_sd/clockworkmod/backup/ - just remember to drop the 0x when you need to enter it

Honestly if more people returned bricked phones/tablets etc... they would quit locking them down... the you broke it you fix it because they want to keep people from doing things they should be able to do with THEIR system they bought... In other words I completely don't agree with this at all.. If everything was unlocked and such then I would support the you fix it, but then again we wouldn't be running into these issues now would we. But then again Most people need people to babysit them and tell them what they can and can't do with what they own..

@wade7919. You clearly have never worked in IT support on a hardware level.
Or maybe, I am barking up the wrong panty-leg?
If you bought a high dollar corvette, GM will support it. If you add an aftermarket chip, and your engine blows, do you expect GM to fix it? No. I wouldn't expect it either. Not their problem. Just because you can add a chip, doesn't mean you should do it.
That's why they try to lock bootloaders. To prevent users from doing things they shouldn't. Unlock them, and it opens a whole world of issues based on "open source". God help us if they unlock bootloaders.....
Not sure what you are getting at. I am under the belief, if you broke it, you fix it. Take responsibility for one's own actions. Shouldn't take the panzy pussyass way (no offence Erica and werecaltf), and return it for replacement. Suck it up, and learn from experience. Otherwise, the next device, you'll do the same stupid thing again.
I like things the way they are. Difficult, but not impossible. That separates the people with balls (again Erica and wercatlf, no offense), from the sheep.
But if you fubar the device, own up to it, and fix it. Don't pawn it off to somebody else (return it). And if you don't have the brain cells to have a backup plan before you start... Well, don't shed tears over it. Own up, throw the testosterone in the garbage disposal, and fix it.
Somebody give me a zanex...
And people, stop using Gingerbreak!!!!!!
Why locking a bootloader will cost ACER billions
Moscow and wade7919, you both make good arguments.
But it is what point of view you're coming form. If I bought a car and changed the RIM's on all 4 wheels and the engine blew up, would GM refuse to honor the warranty?
However, if I put jet fuel and alcohol in for gasoline and blew the engine why would they honor the warranty?
So, the question here is does rooting a device cause actual damage to the device thereby preventing rooting saves them warranty issues? Or is the device also considered to include the software and is covered under warranty?
I'm not taking sides here, but you both are making very good points but with different examples at different points of view.
So, lets look at other items and see if we can draw a parallel. If I buy a brand new Dell computer and send it in for Warranty and there is nothing wrong with the hardware they charge me (correct?). So if I fubar the OS or load something that caused the damage I pay for it or fix it. If there is actually a hardware failure then they cover it under warranty.
So, why does an Android MFG take the warranty one step further and include the OS and take steps to lock it so you cannot change it? Well, this is because nobody owns the OS (it's open source) therefore they take ownership of the build. Because there's no Microsoft to blame, they lock the software and consider it to be part of the overall device (Apple claimed this in their lawsuit). So, in the MFG's mind, there is no difference from the screen, keyboard, or the firmware & software.
So the question is what do you think should be covered under warranty? Most people think it should be just the hardware like a PC. Others see the whole device which includes the OS.
My point of view:
What follows is my rant and my opinion (you are warned )
In my opinion, I had NO problem until they decided to lock the bootloader. I have no problem with them claiming warranty from A-Z and if I change anything they won't warranty it. No problem, I understand that and accept full responsibility. But by ACER locking the bootloader they went too far.
To me this would be like GM welding the hood shut on my car. Better yet, it would be like me waking up one morning and opening my garage to get in my car and discover that during the night GM welded the hood shut. This, in my opinion, is illegal. Matter of fact, in my opinion, it violates US Federal hacking laws because they enter a system and destroyed data. I eventually think OEM's will get a class action suit filed on them for this.
Secondly, Windows 8 is going to be the game changer. OEM's can now make a hardware device and sit behind only warranting the hardware. You have a problem with the OS, call MS. Also, there is a HUGE (I mean HUGE). Did I mention HUGE, demand for tablets in business. Businesses will NOT put a device that has all these consumer games and social networking loaded into the workforce. There are billions in business applications that can be made, but you cannot sell them if they only run on a tablet that cannot have games removed etc.
Example might help: Medical field <- Think of all the applications a tablet can be used to save costs in hospitals. Do your really want your doctor or nurse etc using this tablet on facebook? Insurance company's, law firms, retailers, traveling sales, etc etc (Government). The list goes on.
Developers will see this huge opportunity and will write applications because they can sell them to A-Z and the business buying them will buy them because they can remove facebook and gmail from their company owned tablets. Now, as more and more developers move to Windows they'll drop Android. Want another example, read about Netflix and the issues they have had supporting a fragmented Android OS. So, business applications will move to Windows, but you might say so what, the consumer market is still there. True, but all you need is one killer application that everyone will want and for that to only be on Windows 8. Want some examples, here's my list, NFL (or sports), Netflix, Skype (gee owned by MS now isn't it?), or something new.
Bottom-line is this, if ACER and the others want to lock their bootloaders then they have just taken themselves out of the game for any business sales. Can you imagine walking into a boardroom showing the Government how your new VA application will save the VA Hospitals millions next year alone and improve veterans healthcare. Your application runs on any HC Android tablet. Everything is smoking, going great, as you hand your tablets, ACER a500', around the room. They are loving it. You just hit 'pay-dirt', then someone says hey I see these ACER's have gmail, facebook, blah blah. We cannot have government employees using tablets with those applications loaded, your installer removes them doesn't it? Silence enters the room, all eyes are focused on you. Your mind see millions escaping which were just within your grasp, you pause, you think, and you say YES General as you grab your Motorola Xoom and say 'that's why we recommend you buy nothing but Motorola.'. ACER just kissed millions in sales goodbye (oh and this is a true story).
i do believe acer should lock the bootloader on there devices.
However thee are things I would be doing with my tab if it were not locked.
Acer should give us the ability to flash the bootloader and not use the proprietary software. Lock that software to there bootloader.for there protections.
Give us a wway to unlock it..AT OUR OWN RISK..
So it should be locked but have a way to unlock it with the end user understanding they are totally on there own ..
I would be OK with voiding my warranty.
@Dean,
"So if I fubar the OS or load something that caused the damage I pay for it or fix it. If there is actually a hardware failure then they cover it under warranty."
Yes, that is true. Bootloaders are locked, to prevent completely stupid idiots, from doing things they absolutely no idea what the sam hell they are doing.
The issue is, should we be able to return a device, after we fubarred it? Against warranty? To say, Hey, your weakness allowed me to do it.
Just because the ability to do it exists, and we can quote a thousand instances, It doesn't mean we should, and to shirk responsibility. And pass it off to the main individual.
The fact is, the policies and regulations are there, and we should abide. And if we don't, we have to own up and deal with it.
And if we don't, then we are no better than the low life of the world. The scum.

Very well put.I do know of a few people who have sent there device to acer after messing it up installing rom and telling acer.acer still fixed it free.
Honesty is always best
The evils of rooting
I'm still missing something here, why locking a bootloader does anything. Go get a Mortorola Xoom (not the FE) and you run the unlock OEM. It tells you that you are unlocking it. It tells you that you unlock it at your own risk. You cannot relock it until it is 100% back to stock. It asks you three times are you sure.
Locking the bootloader and treating everyone as an idiot is the problem. Just do what Motorola does, and stop being everybody's keeper. If they want to 'Police' this then you should have to call ACER and they fax you a form. You give DNA to prove who you are and fax it back. Then you go to a mandatory rooting class, that lasts for 5 days, where ACER preaches to you the sins of rooting. Then you have to take and pass a test. Then and only then, after passing the test you get a certificate. Then you call back, give them your certificate ID. Now they give you the secret key to unlock only your tablet.
That's the ticket,
TD
Bottom-line, it's not that they locked the boatloader, it's that you cannot unlock it. Like I said, go out to your driveway some morning and find that GM welded the hood to your car shut because they think you are stupid and shouldn't be opening the hood. Mind you that YESTERDAY, and at the time your bought it, it was not welded shut. That ladies and gentlemen is what ACER did with their OTA.

Okay comparing A Tablet or PHone to a car is stupid... Compare it to a Desktop Computer or Laptop... Companies do not lock them down so you can not use different OS's now do they.. They offer Backups to restore the system back to how it was with recovery partitions dont they? or they offer the choice to buy whatever OS you want to install correct? they don't limit you to say just Windows or *NIX do they? But we don't see laptops or desktops locked down to where you can't upgrade your system yourself or anything else... and any dumdass can do that without an issue most of the time. and there is more issues with viruses and crap on computers than phones or tablets...
So before you start making statements like compare this to that learn what to compare to first. If you mess something up on a hardware level sure pay for it.. if you mess something up on a software level because they decided to Babysit people its their fault. and if you think its the persons fault because they decided to open up a PRODUCT that they bought and own then you are one of the people that need babysitting and like everyone telling you what to do and how to do it. Go to an apple product then.

I still like my car comparison
I make the car comparison to illustrate a point, because when I compare tablets to a PC everyone piles on *****ing about MS.
Bottom-line it doesn't matter if it's a blender or a PC. I own it, you own yours and I can do what I want with mine as you can with yours. Now, again I have a BIG(did i mention BIG issue with them changing it on me after I bought it.
To get back on topic, is the original poster still out there?? Has any of this helped? Are you still bricked?? Give us an update so we know if anything worked or you still need help.
The device was returned and accepted for replacement by the shop.Got new one and feel very nervous to start rooting procedure over.I was really lucky that they did not charge me anything but I really want to know what I did wrong so I don't brick my new device again.
I will provide further details soon about my computer OS and firewall settings and perhaps we may figure out what I did wrong.
To all good guys who send me them suggestions and solutions I wanna say big THANK YOU !!!
Your help is really priceless and thrilled me deeply. Will update topic soon
Happy New Yer to all Android fans!!!
So...Back on the subject.
My device was purchased in Japan and its current firmware version is
Acer_A500_7.009.03_AAP_CUS6JP
Q1. Can I flash US or World Wide firmware version on that device.
Q2. Does anybody know the Acer's ftp download server address for Japan
Q3. I think its a good idea to dump my original stock firmware but it seems there is no way doing that prior rooting.So..kinda stuck .any suggestions appreciated.
P.S. I'm thinking about flashing the latest Rooted rom 3.2.1 V3 by timmiDean (thanks for your hard work) I read the instructions very carefully and I think that everything will go smoothly but just in case (considering the specific Japanese firmware version)
would appreciate any further directions by the author.
Thanks

Something's wrong with my Galaxy S4, but what?

I hope someone can help explain my S4's odd behavior. I'll try to be brief but give enough details for the experts to get an idea.
- The phone discharges to about 30% and then either turns off or starts to bootloop or just behaves weirdly by closing processes and apps making it unusable
- Once fully charged, it'll finally boot again almost normally but first I have to go into recovery and wipe partition and after various attempts it'll finally boot. Its behavior will be normal and everything will function perfectly well until it goes back down to about 30% charge again
- There are 2 things to rule-out: battery and rom. The battery is brand new and 100% original because I've already changed it thinking that it was the culprit. I'm currently using AOSP 4.4 rom but the behavior is the same with any rom even stock roms
- I can't get it serviced because thanks to the new bootloader my warranty is void
Any suggestions?
USB board/port. Replace it first. Given it's quick/cheap/easy to do on the S2, I think you'll find it's the same on the S4. Search online & here for details/the service manuals which might be useful. You could also pay a local mobile repair shop to do it, but why pay them 3-5x (or more) what the part costs in labour to do it when you can do it yourself ?
Thanks! Will try that and will def do it myself:good:. Am pretty familiar with hardware. I too think at this stage that it's a hardware issue

Just out of curiosity, why do you think it's the usb port? I have to say that it crossed my mind once as well because on a few rare occasions I had problems charging my phone as if the usb cable or port was defective. My PC at times has also had problems recognizing my galaxy when plugged in, but only very rarely so I didn't make much of it
The charging issues you've had, another battery not solving those issues, and the auto shutdowns/auto bootloops for no reason have always been symptomatic of the USB board/port on the fritz on the S2 and the S3 (saw so many of these in S2 Q&A this year particularly), just sounds a lot like it. Put it this way, if it's not, it's something much worse hardware-wise, but I think you'll find the easy fix will resolve it in this case.

Need Help with APX Mode Brick.

Running (was) a stock rooted N7 v1 on 4.3. Bought a data recovery tool off of the play store to try and recover some photos I had deleted. At some point it rebooted into safe mode, my battery was running low and I shut it off to let it charge. Now it's dead in the water. Stuck in APX mode. I am asking if there is anyway to breathe life back into this tablet.
The tablet does nothing on the screen, period, no matter what you do. When plugged in to a computer it sometimes registers as an unknown device, sometimes APX. None of these get you anywhere. Toolkits on these forums won't recognize the device, installing the android development kit and drivers does nothing, executing commands from the command line is worthless because the device won't register. I do not have any "blobs" and have no clue at this point even what they are or what they could have done for me had I made them.
I've searched this forum and found bits and pieces here and there and wanted to start a thread dealing solely with devices stuck like this and what has or hasn't worked and get others input if warranty service was done and the state your tablet was in when you sent it in (locked/unlocked, rooted etc).
Anyone stuck here will have probably tried the same things as I have but here is is a minor rundown...
1) Every button combo press known to man for short, medium, and extended periods of time.
2) Charging with the Original charger/cable for 1 hour, then button presses then charging for 12 hours.
3) Same as above but with different aftermarket chargers at different amperages.
4) Uninstalling and deleting drivers. Trying different drivers. Getting the Android drivers etc.
5) Trying every toolkit on the forums to no avail because the device won't register.
6) Checking to make sure the battery cables are seated correctly.
7) Screaming and yelling at your new paperweight.
My hope here is that I've missed some important thread about recovery and someone can point me in the right direction. Failing that, if I should get a new mobo or try and send it in for warranty service in the state it's in.
Any help would be much appreciated.

I don't know what you tried before to revive your tablet and what the tool did to get you into this state, but generally APX mode can be left by pushing the power button *only* for about 10-20 sec, as long as there us enough power within your battery and the hardware / software is working / consistent.
Sent from my Nexus 7 using xda app-developers app
I don't think I've ever seen anyone in here describe a situation where they observed the tablet in bootloader mode without seeing *something* on the screen.
And as you found out through your reading, using "nvflash" on the N7 is only useful at this time for folks that made prior disaster recovery preparations. So, APX mode is of no use to you (at this date 12/2013).
So, until you see something happen on that screen, drivers on a PC are of no value to you anyway.
It is really unfortunate that the N7 doesn't have a physical charging indicator - that makes it difficult to distinguish between a tablet which is truly borked vs. one that refuses to boot simply because the battery isn't charged.
Holding down a specific button combo (iirc Pwr+VolUp) during an attempt to get "something, anything" to happen will put the tab into APX mode, so it isn't particularly diagnostic that you have observed APX mode once or twice.
Really about the only way to know if the battery in a non-responsive N7 is charged or not is to put it in another tablet or measure the open-circuit voltage. (About 4.15v fully charged & about 3.5v discharged)
The reason that I mention this is that there have been a few reports from users in similar straits as you that report something like "I don't know what happened, but I tried it a few days later and all of a sudden the tablet booted up". Almost every one of those reports involved mentions of low battery conditions, just as your narrative does.
I don't know what file recovery program you used, but I suspect that is a red herring . It might have to have root privileges in order to read raw partitions, and might even want the tablet in safe mode to minimize write activity by *other apps* while it does it's forensics, but it certainly isn't going to recover files by writing in raw mode on a mounted, live filesystem - it would do all it's writing through normal kernel syscalls. That's the long way of saying that a low battery is more likely to be the original source of your troubles.
So what to do now? I think the first order of business is to figure out if your battery is charged or failing to take a charge. If it really is well charged, then a warranty return is probably in your future.
If you can't find a second N7 or a voltmeter, then you could try just leaving it on the charger for a couple of days... but that really is just a "grope about in the dark, wing & prayer" kind of strategy.
good luck

You are in the same situation I was in - nothing shows up on screen. I got APX drivers to finally install (had to search all over the internet to find them) and that STILL didn't help. I was never able to get it to come back. Nothing ever showed up on the screen.
No combination of button presses helped. I finally gave up and, since my N7 was still under warranty, I RMA'd it back to ASUS. It took about 3 weeks, but I got it back with a new motherboard installed on it.
It was borked and your's sounds the same way as mine. Just either register your N7 on the ASUS website and RMA it that way, or call it in over the phone and RMA it that way. Hopefully, you still have the box your N7 came in because you'll need the serial number.
Others have stated you can get it by opening the back, but that will void your warranty. I do believe you MUST have the serial number, so find the box and get it from there.
Also, you'll definitely lose everything that was there, especially if they replace the motherboard. So hopefully, you backed it up. I backed mine up just before it got borked, so I was lucky.
Good luck!
I am wary of trying to do the battery swap. I went and bought a new version after it crashed but I would be voiding both warranties to try the battery swap.
I do have the serial number if I want to try and get service.
I have done some reading about "deep discharge" battery issues and I suspect this may be a part if it but I have tried leaving it plugged in for days and nada.
I don't know if there is a way to "shock" or jump start the charging process and I am going to put the multimeter on it tomorrow and see what I get.
Thanks for everyone's input. I will keep you up to date.

Cannot use Google PAY

I bought this 6t refurbished and I suspect is a t-mobile converted to global. I've tried resetting the phone and deleting all kinds of apps cache/data to no avail. in addition I tried to get the
Google Services Framework Android ID but my phone is not rooted. i would like to keep the phone as stock as possible.

Did you convert your tmobile to international ? I guess you did. So either root it and install magisk or livr without Google pay.

When you go to About phone the build number will tell you if it is T-Mobile converted phone. If the build number starts with ONEPLUS A6013_34_ then it is converted, if it starts with ONEPLUS A6013_41_ or ONEPLUS A6010_41_ then it is a global version.

Well you can't do really anything but if you have not had it too long you could return it.

You have 3 options:
1. DO nothing and hope OnePlus will fix it down the road. I actually lost hope with this one.
2. Load T-Mobile version, and loose dual sim capability. Google Play will pass certification and Google Pay will work.
3. Use Magisk, at your own risk, to trick SafetyNet check.
I have one of those scammy "no warranty" T-mo -> Intl. OnePlus 6T and, with enough work, it is possible to convert to the most recent Intl. android 10, and get root and Google pay working. I don't think at this time it's possible to watch Netflix in HD while having your cake and eating it too, sadly. The A/B situation on this phone is painfully confusing and leads to brick after brick as you learn the ropes of this phone. Not sure that's TMo's fault. Thankfully the bricks are fixable. You need the modded flasher for 9.0.11. From usb serial mode, the flasher gives some gibberish "Sahara" error. There is whole infuriating thread consisting of nothing but post after post of newbs being shamed for asking how to fix this problem (because it's already been asked a million times) but no clear concise solution ever provided (just a bunch of conflicting half-answers i.e., "I finally figured it out after mashing buttons for a long time..." -- What worked for me was holding down all the physical buttons, vol+, vol- and power, with the red "Saharah, please fix..." (something like that) red error message blinking away at me on the computer screen, and the phone plugged in to computer USB, the whole time. Only when its air composition sampling system detects your fingers bleeding profusely, will it kick in and fix your bricked device
So that gets you to an equivalent to a locked Global 9.0.11 rom with no OTA updates. From there you can do developer mode -> unlock bootloader instantly from fastboot -> (loose all your data) -> TWRP; now the a/b stuff gets really confusing AF but if you do TWRP from fastboot->flash 10.3.2 -> TWRP from fastboot again (it's like ms windows!) -> flash TWRP .zip installer -> TWRP from fastboot yet again -> Magisk, you can finally boot system.
To pass CTS profile you'll need to use the command-line signature changer Magisk module and Magisk Hide. Once the play store says it's "Certified" (certifiable more like...) and Magisk is giving you two green checkboxes, you are ready for more suffering. Now you need to freeze the Google Pay/Play apps and Google Play services and blow away all their data. At least that's what I did. Then make sure Magisk hide has all the Google play/GMS/AR/pay stuff hidden in Magisk, one more reboot for good measure, and you're off to the races. This gets Google Pay working and even lets you watch DRM at Widevine L3 level... it's still not all your cake and all your eating I suppose... hopefully you're not a big Netflix guy. Otherwise you kinda bought the wrong phone.
GL! Oh btw I have not found any way to restore an encrypted TWRP backup on this device. Starting to suspect it's literally impossible at this time -- but, if I'm honest, probably I just haven't gone through enough suffering, yet, to figure it out.

Nope. Just completely dis-confirmed the above recipe. I am clearly still well in the cargo-cult phase of my OP qdl client tools education
All I can say for sure is randomly frobbing with the buttons and the phone-side usb-c cable for long periods of time will usually eventually start the process. And one sure-that-I'm-not-sure---but-still-fairly-confident correction: It probably helps to /un-/plug the phone from the PC, once it starts giving the meaningless red "Sahara quintessence frobnitz poop" error message (or whatever equally meaningful thing it actually says). If you find yourself in TWRP, you can use the "Reboot edl" button. Likewise, I believe the stock recovery has an interface to jump to qdl mode... could be making that up though Anyhow I think from there you want to turn the phone entirely off, which I believe can only at this point be achieved through continuous, uninterrupted mashing of the power button. So just after your get the error and disconnect, is your opportunity to impress the phone by bleeding all over it.

OK, I think I figured out an actual recipe now, or the beginnings of one. It is still a bit fuzzy in places. It goes like this:
If you're not in qdl mode, or you are there but it won't talk to the proprietary flasher software, get the phone completely turned off. Often this is the hardest part. I have sometimes managed to brick my phone where it will Boot and insta-freeze at the infuriating-yellow-triangle screen¹. Then it will just sit there, indefinitely, and never bring up any sort of USB or wifi connectivity (nor does it show any sign of boot-looping, judging by dmesg output on my computer. It's just cold, and dead. Probably a bootloader bug/secure boot fail). In every semi-brick-like circumstance like this, I've found the following enables me to get the phone to turn itself off reasonably quickly, in fact, in just a couple of seconds, usually: unplug any USB-C cable (so I'm running on batteries), hold down all the buttons* until fingers bleeding or something happens -- if nothing happens, release all the buttons briefly and try again; once off, release all the buttons immediately.
Now get the phone back on, and in qdl mode. Somehow. Usually, if the phone is unplugged and off, I can get it there by holding all the buttons and plugging it into usb. If I'm soft-bricked, I'm already there, so nothing to do. From TWRP I can easily "reboot edl" to get there. Maybe there's ways to do it from fastboot, stock recovery, and system as well, via adb/fastboot commands.... My preferred way is holding "all the buttons" for about 1 second, and plugging in the usb cable, which will cause it to enter qdl mode "just one time" without actually bricking anything.
Now, finally, we run the proprietary flasher tool. Press start and it will go until it gets to the "sahara bingo yip-a-dee-ha" error (or whatever it really says... definitely not exactly what I wrote ).
Now turn the phone off again. Same recipe, but this time it seems to almost-always suffice to keep the phone connected to USB, while holding all-the-buttons. If that isn't working, then I go ahead and unplug, power cycle, and get into qdl mode like above. During this, the computer software is maybe completely disconnected from your phone, *****ing and moaning the whole time about Sahara or whatever. Ignore that, it's fine.
If the phone was fully powered off (rather than power-cycled in place), be sure to next release all the buttons, so that the phone has no usb or button-press input of any kind for at least a fraction of a second. Then press "all the buttons" again (nb: I suspect just vol+ and vol- suffice here, and the power button is superfluous? Maybe even detrimental depending on ordering? If I screw this up (sometimes it winds up booting into recovery or bootloader), then I find a way to ask it to reboot from there into qdl mode, if I can, or else power off from there and try again to use the three buttons.
pro tip said:
It is possible to hold all the buttons for too long. In which case, you may find yourself booting system. From there you may need to start this guide over from the beginning, sorry. The correct period of time to hold all the buttons down is about a second. Two seconds is probably too long.

Using your fourth hand, Plug in a USB-C cable, what leads from your computer, to the phone, while continuing to hold down all the buttons with your other three hands (or, if you entered qdl via software, just plug it in, now).
That's it, done. Kick back and enjoy as the tool's progress bars go wild and unbrick your phone tut suite. The qdl process should be able to go all the way to the end where it says "100%" (although when you close the program it will still treat this like you are interrupting it in the middle; I think that's because it does multiple phones at once, and you only ever fed it the one phone, so it is alerting you that, hey, phone #2 never got processed).
I am doing the above in a non-FOSS emulator under desktop linux, using the patched client referenced from xda threads.
I imagine qemu would work, as well. Obviously native Windows is going to be your best bet. I def. wouldn't trust Oracle (VirtualBox) USB emulation with my qdl flashing needs, if I were me -- which I am. Phones tend to look like huge USB hubs, full of an ever-changing kaleidoscope of peripherals. Which I don't think the VirtualBox USB stack is really ready to cope with right now. (Not even with the proprietary USB add-on pack or whatever that is -- I simply don't trust Oracle not to hard-brick my phone; VirtualBox has seemingly perma-bricked one device for me, already. That was some time ago but I'm not going to feed it any more devices and I doubt the USB was fixed in vbox. It think it's paravirtualized, or something, so as to be super-fast, but unreliable when the bus topology changes in meatspace.

¹ You know, that warning screen for "security." Which, currently, happens to be punishing me for trying to put the newest stock security updates onto my phone that I just purchased a month ago¹*².
* Not an "All the things" meme -- by "all the buttons" I literally mean all the hardware buttons: [vol+], [vol-], and [power].
¹*² I imagine the person who made the decision to require this in Android would explain it something like this:
straw man said:
(California accent) "Um, like, why? Are you a criminal or something? You know, you could just buy a new phone for like $899 US. Oh, you're, like, poor, or something? Well, OK, I guess there's no way for us to stop you from doing that. But we, like, won't be able to support you in any way. Also, sorry, but we're just going to need to put a brief warning screen on your phone, as a safety measure? No, it's not really a warning for you. More, like, in case other people might be around you for some reason? It just says, 'Hey, no judgement, but it seems like maybe a poor person owns this phone? And they're definitely doing some really weird stuff with it. So just be careful. Like maybe tell a friend where you're going, if you're going to spend time with them.' What? No, I'm sorry, there's no way to remove it. We paid millions to have it fused into the microchips or something? If you could just remove the warning, that would defeat the purpose. So, I'm sure you'd want the people around you to be safe, right? And, like, so do we! So we, like, locked that down pretty tight, yehh-...!'
