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.
http://forum.xda-developers.com/showthread.php?t=1291747
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.

If its new just return it to the store for another one.

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
...or at least a thread dedicated to A7+
The A7+ is out there and it is different. How much is different I dont know, other then official specs. Maybe its still to new or the type of buyers (shopnbc) just dont visit forums like this. Is the A7+ even available anywhere else?
Anyway, i'm sure people are going to be interested in what applies to them and what is just exclusive to original A7, are any of the mods needed/wanted, etc.?
Shopnbc just did another bundle sale, so im guessing there are a lot out there, other thing is elocity mentions XDA so more of us "not to tech incined newb's" may be comming
A7+ to update or not?
just got my A7+ at Christmas. There is an update available from 2.2 to 3.1 at the elocity site. has anyone tried it successfully yet?
I just tried yesterday with no luck, download failed (directly on my A7+)
Probably better for me anyway as I often open a can of worms when trying stuff like that without some guidance
I noticed for the A7 updates there are detailed instructions and you go through yor PC or Mac but no instructions for the 7+
Do I need to prep and save before an update? Also they don't decribe what update included
i called the elocity help lline because i was unable to download the update to the tablet> they said it had to be downloaded to the a micro sd card and the installed from there.
A7+
I really like this A7+. I updated to the new firmware -- it was painless. I'm not sure what was updated. It's still froyo.
It would be nice to have some mods for the A7+ to get the android market, google apps, etc. It sounds like people who used the A7 mods ran into trouble. Has anyone had success on the plus?
i may give it a shot this Fri, it's my next day off that way i will have the whole day to devote to making the update work and not create a brick.
Wow am I glad to find this page, I just purchased this tablet 7+ and already need help, btw it arrived yesterday from shopnbc after having a nook tablet, and hope someone can help me want to get my kindle books have the app however it says sync failed and there is no place to get my book from archive like I can on my Iphone. Secondly what is this new update and is it possible that I have it if so how would I find out. Thanks everyone will for sure be reading all I can about the tablet fron here love the developers.
Yes please, I want to love my new tablet so bad, but Froyo is keeping me from this, and firmwares ported over for the A7 don't work on the A7+. I would love to have Honeycomb or better yet Ice Cream Sandwich for this device. My wife has one of the cheap Allwinner A10 tablets and there are a ton of different firmwares for it. It will also play HD video, which is an issue for the Tegra 2 chip running less than Honeycomb 3.1
At last, an inexpensive multitouch tablet
I just picked up a factory refurbished A7+ for $120 (Toronto, Canada) today and I must say, its touch screen is just about on par with an iPad. I would love to be able to upgrade the unit past v2.2 and at least to Gingerbread but there doesn't seem to be anyone looking at this device on XDA at the moment.
I'd be more than happy to help with hardware mods for the device.
Might creating an A7+ section in parallel to the A7 help differentiate the two devices and prompt some work on the OS?
If you want to have a look at the guts of the unit, go to the FCC-ID OET site, plug in the FCCID (GKR-NAZ10WB) and select the "detail" list.
I noticed that the docking connector is actually on a daughter board that plugs in to the main board. There is no docking connector on the A7+ but there is on the A7.
I also saw there is a slot for a GSM card in the photos!!!
I'll have to open up my unit and verify if my A7+ has the GSM card slot.
Stay tuned
hey bigbop,
did you also notice in those pictures that the board has a netbook style ssd connector ?
I am willing to bet that it has a 4GB ssd attached to it instead of 4GB of flash soldered to the board..
hummm I wonder ... 64GB A7+ anyone ? plus whatever microSD card you jam in the top.
comments from any of the more system savvy people about ghosting the original system to a different size "drive" ?????
Well, unfortunately the A7+ motherboard is different from the A7 in that the internal gsm card slot has been removed and the connector that the docking station daughterboard plugs in to is not installed (the pads are there so you might be able to hack together a cable to bring out the signals for an additional interface)
Actually, does anyone have the specs on the A7 dock? What external ports does it provide?
The chap I bought my A7+ from told me that his wholesale guy (in Canada) had bought five hundred units (at $50 a pop) and they were officially designated as "Factory Refurbished" - he sold them all in two weeks. I've seen them in other places too lately, popping up around the $110 mark. It is a fantastic device, touchscreen is great, Netflix runs great. Easy to McGyver into markets or Apps. I know that Elocity have released the A7 and A7+ kernel information (the A7 package is 432mb and the A7+ is 115mb for some reason) so we can hope that a developer picks it up and runs. If the parent company are jumping ship on the market we can see 50,000 of these units in the hands of people hungry for Honeycomb, well, we can all dream I suppose...
IMHO the A7+ would be a great tablet IF Elocity would release an Ice Cream Sandwich ROM for it. As long as the A7+ is stuck at 2.2 you are better off saving your money and buying an Allwinner A10 based tablet. The A7+ hardware is great, but the OS is garbage. Mine never wakes from sleep, and can't play ANY HD video smoothly. I paid more for the A7+ then I did for my iview TPC760 or my Kindle Fire, and the A7+ is defiantly the biggest turd of them all.
play store 3.5.16 working like a charm on A7+
will repost this on end of get market working on a7+ thread
I followed the destructions provided here (use at own risk, worked perfect for me)
http://forum.xda-developers.com/showthread.php?t=1431967
Thank you Destron5683
with a few exceptions, as noted in the reply's most people had to manually reboot
I bought root explorer on amazon market, required for getting base market working.
Once you get that up and running it's fairly straight forward to install
play Vending-3.5.16.apk (destructions below) which is available from this thread
http://forum.xda-developers.com/showthread.php?t=1582422
scroll to bottom of first post and look for the attached files, I used the non mod version, save this file to root of an sd card
Thank you Deeco7
Again follow at your own risk, this process worked for me, it may not work for you...
I kept an sd card in so I could backup the file in a place that won't get overwritten/deleted if I have to factory reset at some point
open root explorer, make sure your at / in upper left corner, next navigate to /system/app scroll down list to Vending.apk
, long press, copy, hit back twice so your at / again, navigate to /storage/sdcard-disk0 (or wherever you prefer to save backup)
press paste, now rename file to Vending.bak (or whatever you will remember)
rename the Vending-3.5.16.apk to Vending.apk
long press it and select copy, navigate back to /system/app , hit Mount R/W , delete Vending.apk , then paste your new Vending.apk into folder.
hit back button untill root explorer exits, then shut off and restart
you should have Play Store icon in app bin, press it and enjoy.
not sure if it was my router or isp or tablet, apps didn't want to start downloading in play store,
as soon as I exited from play store it had downloaded 1 app and was getting the second one,

Non Mod version
Hello Ryan,
What is the difference from the Mod version and the Non Mod Version? I have rooted using Z4root and I would like not to install any Mod on it since at this point it breaks camera on Mods that I seen. This Market (Non Mod verision) does it allow to install software that it would not normally install on the system or do I need to edit the buildprop in order to do that? I am looking for older versions of Netflix and Skype to go around the issue (hopefully that works) so I can have a fuller working tablet without changing much on it. I know that video does not work on skype, but the voice and chat should work on version 2.0.45 apk. I also heard that netflix version 1.3 would work.
So, I was re-reading the schematics, and while I was looking at the boot settings/hardwired configs (page 18 of the 44-page document you find floating around the web), I noticed there is a way to set a RECOVEY_MODE# flag (seems to use a pulldown resistor for that), setting either "USB Recovery Mode" or tell the SoC to "Boot from secondary device'
I can't really afford messing with my N7 right now, since phone #2 is dead and the good old TF101 needs a new cable...Anyone got any ideas on this, or has a spare, semi-dead/semi-unusable device to see if this has any useful functionality? Might save people who are bricked and without NVFlash/APX blobs...Will try to get my hands on a dead device to push this farther.

This is a good idea to try pull down this signal and get the recovery mode but you need to try. I am not sure if it is workable. your experience will help us to save N7's life.:good:
BTW, would you please tell me how to get the device's schematic. I dont know whether we have the opportunity to get a gsm phone call if i have the schematic.
Like I said, I have no fallback, so I can't be fussing with my N7. @p5auser, PM'd you the link...Anyone with a bricked device or broken screen?

it is difficult to read the schematics on the website. i will try to print out. I had ever bricked my N7 device after doing firmware upgraded and went to RMA.
The RMA replace the internal PCBA. so i recommend you go to RMA if your warranty is valid.

The point is, people that are desperate enough to fuss around with the hardware (and have the knowledge to do so, reading schematics included) to try a fix are most likely out of warranty. Also, the Grouper/Tilapia models have been replaced already, and most of those units are over 1 year old, and thus, out of warranty. I, personally, don't have such a problem with my tablet, but I wanted to see if this is helpful to anyone. It's just a matter of reading the table contained in the document, finding the mentioned resistor (or it's place) on the board, and mod it.
Anyone owning a Fire 7 needs to stop drop and roll...literally. Please go to your tablet and with a file explorer (i don't know if you need root) in the root directory please try in whatever way possible to read the contants of all files (theres like 3 or 4) with 'fstab' in the file title. Look for ANY properties ANYWHERE that have to do with 'acm'. I am fairly certain, without root you can persist this property in ADB. Get your tablet, plug into PC and open ADB window and type:
Code:
adb shell setprop persist.sys.usb.config mtp,adb,acm
Your PC will light up like a christmas tree with new drivers for the tablet. If it does, then the chances are VERY high that you will be able to root and unlock your fire 7. This is almost certainly going to work on the HD 10. https://forum.xda-developers.com/hd...fire-hd-8-2018-downgrade-unlock-root-t3894256
Turns out I wasn't crazy or stupid after all !!!!!! All I ever asked was for you guys to just listen to me and understand I knew exactly what I was seeing

Can you explain what is the acm mode, its bootrom download mode? I do not understand what we can do with the tablet in ACM mode. If we do not get the tablet to enter the BootROM Download Mode this mode will not help us at all.
How does the computer detect the tablet when it is in ACM? I tried it on my Fire 7 and it does not install any driver ...
EDIT: I read this:
Code:
Before Download mode can be entered, the Preloader has to find out if a host is connected via USB or UART and running the MTK SP Flash Tool. It does this by configuring a virtual CDC ACM discipline on USB, so both lines are in fact serial ports and behave similarly.
The USB port will assume that the tool is connected if it receives a “set line coding” (configures baudrate etc.) CDC message. It then sends the string READY to the tool and waits for the reception of a token of eight bytes.
After successful detection, the tool can send the special Start command sequence (0xa0 0x0a 0x50 0x05) to enter a special mode that is only available via USB. It interprets the following commands (I left the ones marked with “legacy” out):
Its seem that ACM mode its Download Mode

ACM allows a device to emulate ports. Example: the tech doesn't have a usb port to connect the tablet. ACM can be used so the tablet emulates a different port other than USB. In our case, ACM appears to be the God mode.

Had this device before. Got a new phone and gave it to my brother. But can you explain a bit, just entering those acm commands wont give you root, I know but what after that?
Will check this method when I go to my brother's.

ACM is a proprietary function mediatek uses to emulate the USB port as a different port so they can access their devices using various hosts. It's also a way for them to access the device without modifying the firmware or system. It's a clean, legit way an oem should access a device. This explains a lot of my discovery that kicked off this whole process. We could see all this happening in the HD 10 binary files, but we couldn't see how this access was happening or where it was coming from. My theory was Amazon used a back door and a mode or user ID greater than super to access devices without the use of private keys. Of course that was crazy talk and impossible and I can't blame any one of you for not believing me. I however never imagined this going beyond Amazon. I'm honestly in total disbelief that any of this is happening and even more so that my crazy cat lady theory was right from day one. I'm just greatful and honored that the few of you who didn't think I was crazy, took it to the next level. If it weren't for all of you, my theory would have been buried and forgotten. In the 3 years since I started all this I never imagined it would come to this. All of you are amazing!!!

ACM isn't a proprietary function from mediatek. TtyACM is typically used for modem-devices, but in the end it's just a serial-connection.
And the ACM you are enabling using this command has nothing to do with the ACM of the BOOT-ROM.
Also this has nothing to do with amazon or backdoor-keys or any super user access.
It is an exploit of the mediatek boot-rom which is part of the SOC and cannot be changed.
They are totally different things.

Does that mean the 2015 Fire 7 in (5th gen) may be able to be rooted? If so, do we have to do the thing where the back of the tablet needs to be opened and the pins have to be grounded?

If device is running FireOS 5.3.1 or lower it can be rooted via software hack. Otherwise, you'll need to crack open the case and play the pin shunt game.

Don't have to open the case! Need to start by bricking with 5.0.1 sideload, then you can talk to 5.0.1 preloader as in here:
https://forum.xda-developers.com/amazon-fire/development/downgrade-fire-7-2015-softbrick-t3894671
It'll be bricked with 5.0.1, but preloader with get into Bootrom via a button push, and that's all you need.

Yes it already does. A bit limited by the current low knowledge of the hardware but it will improve with time
and some software tool to help less skilled people avoid to have to do with a soldering iron and/or disarm the tablet.

Well that's an interesting approach and one I would not advise to the faint of heart. That said, it's probably the path I'd pursue on a personal device that I would be willing to sacrifice. Advantages of 5.0.1 bootloader outweigh other considerations in my world where simplicity, stability and minimal maintenance outweigh redirected blood flow.

Why not advice? Definitely safer than opening it up and poking around with a paperclip
But sure, if you have a rootable OS and that's all you desire both methods aren't for you.
That said the tablet is now basically unbrickable

It can need a paper clip and opening the device as well.
"With older preloader-versions you can then simply hold the left volume-button while pluging the device in.
If you have a newer version, you will have to open the device and remove the metal-shielding (it is clipped on)"

Most of my varied devices are bootloader unlocked which affords full control over hardware and flexible recovery from all but the most aggregious flubups. Not my first stroll through the turnip patch. That slobber lined path is far removed from experiences of the common user. Intentionally bricking a working device is not guidance I would give lightly during the early stages of exploit exploration. Same goes for blindly probing around the circuit board with metal objects. Die hards will eagerly take the plunge regardless of risk and share their experiences, good and bad, with the community. Tip of the hat to those bold adventures. Only after the liabilities and rewards are fully understood would I reconsider guidance for non card carring members of the geeks-r-us society. Seen plenty of noobs go down in flames naively following supposedly 'easy' instructions to nirvanaville.
Simply put .... a suggestion for the novel user poking around in the hardware is enough as a sign of being helpful.
Why should we insist trying to make them stay away from the world of electronics ?
I just suggest to start using a resistor about 1kohm when shorting test points or pads on the motherboards working from 3V to 5V.
This gives them a minimum margin of safety and potentially avoid or makes it less probable they burn some components on the PCB.
Later on they can try to lower that resistor value to a value from 100ohm to 200ohm if they didn't had the expected results and retry.
Many will burn some of their stuff, yeah ... why not, they are used to it. They paid for it and deserve to do what they want with it.
My view though, everybody has the right to express different point of view.

Agree with all the above including the sensible cautions. If one understands the basic function of an electrical resistor and the units involved then there is probably both interest and knowledge to proceed. Now we've addressed the 5% club I submit the rest should stay on the sideline until more is known. Same for the brink-n-revive suggestion that started this exchange. I hold no power over what individuals do with their devices. I can only provide guidance based years of experience that extends well beyond hand held gizmos.

I agree with both of you, all I'm saying is for those who have made up their mind and want to do this, I think bricking intentionally and then using the exploit is the safer route, since it's a software-only solution.
With poking around on the mainboard there is more things that could go wrong, I've seen people shorting VBAT to ground.

ITS SOLDERED ON! In Austin
Hello, first post here, somewhat of a noob but not completely. Please tell me if I am using the wrong lingo on specific things.
Fire os 7.3.2.2
I am looking for information on the locked rom of the 10th. Gen hd 8, a have read quite a few threads from the past two years asking if there is a proven method to get in but I couldn't find anything promising. I did run across this one website that claims it is simple, just unlock the bootloader first.https://www.rootingsteps.com/root-amazon-fire-hd-8-2020/
Of which I can find no information on how to do. There is an "oem unlocking" switch in developer options but it automatically goes to "off" after clicking it on and selecting "ok" on the device protection pop-up.
I also am aware of the 8th gen method and i have the back off my 10th but it is completely different.
I am willing to help any way I can, that being said though if everyone has given up on these I could buy an 8th. but with the sale amazon has the newer one is almost cheaper than a used 8. If anyone is interested I'll upload pictures of the circuit board, there is no clock pin marked but I would think it is still there, and I will try shorting it to ground, and if it lets the magic smoke out I'm sending it back to amazon lol. If it makes any difference I don't need to save anything that is on the tablet now, it's new, never account linked, or connected to wifi and I'd be fine with completely wiping the fire os and everything, if there is a way to load linux.
My goal is to load linux mint and run it as a touch screen "laptop" to use as a digital dash with Tuner Studio on stand alone efi on a "race car".
