Hello everybody,
I have a problem with my Touch. A couple of days a go my phone was empty, when I tried to power it up again and start it, but then it hanged in the first screen (the T-mobile screen for my phone). I read a lot on this forum, but I'm a newbie so it's hard for me to find the good solution. I could get the phone in the bootloader ( triple color screen), but it doesn't give the RUU letters in the right corner. If I connect the phone threw usb to my computer, it doesn't give me anything. Active sync doesn't go green. I tried the following things,
1. Go in the bootloader (this works!)
2. Disable the USB connection in active sync
3. Start an USB-sniffer (didn't find my phone)
4. Tried to use MTTY (gives me the error, can't open USB connection, something like this)
5. Tried to flash a rom while in bootloader screen, but the flashing utility can't connect to my phone.
So the main problem is that the phone can't connect to the computer, what do I have to do, to put a new rom on my phone, so I can start the damn thing again??? Please help
Thanks
have you tried hard reset ?
still nothing
I also tried hard reset, still hangs in the first screen, there's also a new problem. I can't put it one, and when I put in the adapter (to charge) it give a red light (constant), what to do, what to do?
no tips?
nobody has any solutions?
I have two A500s and have rooted and flashed them both successfully.
One day my main tab, the other is for the family, was working then it just stopped. It would boot to the "Acer" logo and go no further. I left it like that all night with no result.
So, I figure that I'll just flash a new rom to fix it. I tried 6 or 8 different roms; all booted only partially like before. I did a factory reset, flipping the screen lock back and forth. Still would only boot part way and hold. I continued to look for different roms (what do they say when you keep trying the same thing expecting different results?).
Now the tab doesn't seem to come on at all; that is the screen stays dark. The light on the power button comes on and I can turn it off by holding for 10 seconds and turn it on again. I connected to my PC and it requested a driver which I installed. the PC makes the "new hardware" sound but I don't find it in "My Computer".
I have tried to access it via “adb devices”, but no devices are detected.
This is the extent of my efforts and knowledge. If anyone is able to help please email me at [email protected]. I have been reading the blogs and am posting this to several blogs so I might not find your answer if it is to the blog only.
Btw,
I did find a post that describes something like this on an A200 at this blog:
http://www.acertabletforum.com/forum/acer-iconia-a200-help/5895-solved-my-a200-wont-turn.html
I'm tempted to attempt it if I don't find an answer specific to the A500.
THANKS IN ADVANCE FOR ANY HELP!!!
==================================================
edit: I tried the A200 solution to no affect.
bricked a500
I have the exact same issue, does not go past acer logo screen and Win 7 does not show the device when connected. I can hear the sound when you plug the usb cable but nothing visible or no icon on the screen.
Any help would be greatly appreciated.
Thanks

Hello!
I turned on my MK802III and went to: Settings -> Video -> Scaling options -> 100%, and the screen started showing some odd pixel lines, mouse and keyboard stopped responding. After a few minutes, I unplugged the device, and now it just won't boot.
Now, the blue led turns ON and the TV recognizes that there is a signal, but goes to EnergySaving mode, and absolutely nothing else happens.
Any ideas? There is not much information around the internet about this.
Cheers!
PS: It was the device first boot! I had just received it.7
__________
UPDATE:
I guess I might have reached a conclusion...I think that the device might be boot looping. So I googled about how to restore/update firmware, but a needed a way to do this without having access to any of the device's UI. So I found a recovery method by short circuit at Armtvtech and there is also OFFICIAL information about this.
After downloading everything needed, I proceeded to short circuit the device. Everything ended up OK: drivers installed successfully, Rikomagic's tool detects the device, BUT after chosing the .img from Rikomagic's files and clicking 'update', the tool returns an error.
SCREENSHOT
Now I'm stuck here...can someone please help?
Hmm. Just got one myself Google rikomagic forum there is a sub forum with ROM list thread. Most roms include flasher im using finless 1.7a. you can reflash nand from windows. Unless was a hardware damage?
There's a reset button same side as USB otg. You have to have flasher prog on PC running and hold in reset while device connects like 10 secounds . install driver rinse and repeat run flasher

Could it be possible you are useing wrong version of the rockchip flash tool? The version you are useing may see the device. But wont flash. Try different one for your version of windblows and the device itself. Good luck.

Hi all !
I have a Samsung A8 (model SM-A800F) which was working great. I ran Kingo Root to try to install Youtube ad free. The next time I restarted it, it didn't load, and restarted in an endless loop to where "Samsung" logo appears (then restarted again). I booted into System Recovery and chose to reset to factory, but it didn't help. Then I tried flash it using Odin in Download mode. I installed the Windows drivers, downloaded the 6.0.1 firmware for Vietnam (where it was purchased), loaded the file into the AP field, and once verified clicked Start. The progress was frozen when reaching mid-way every time I tried, until it said "an error occured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software"...
I downloaded Smart Switch and installed in Windows, but the drivers were not able to install correctly, and failed on the component referring to the ID or something... while Modem driver was installed correctly and the phone appeared in Device Manager. Smart Switch didn't recognize my phone and said "unsupported device".
Now I cannot get the phone stay constantly ON, and the screen shuts down and loads in an endless loop, to the "Error occured" screen... When trying to boot to the ODIN Download page, it loads, I press UP for Continue, and then it again shuts down and loads to "Error Occured".
I tried to charge over night but it didn't help. It does the same thing when the phone is connected to the charger...
However it seems that by IMEI it is sill under warranty. I'm not sure if I voided it :/
Here's what the Download mode page says:
ODIN MODE
PRODUCT NAME: SM-A800F
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
FAP LOCK: ON
Secure Download: Enabled
KNOX WARRANTY VOID: 0
AP_SWREV: 1
Would appreciate any help, this phone is almost new but now it's dead :/
Your warranty is not voided. Your Knox E-Fuse still intact.
Also this is for S8 not A8 forums.

No worries, your phone is not dead.
Try to find a firmware that correspond to the one you got :
http://updato.com/firmware-archive-select-model?exact=1&q=SM-A800F
and use ODIN : http://dl.sammobile.com/Odin3-v3.12.7.zip
You should be good to go.
EDIT : Also for that error occurred thing, try to be faster than it by starting odin flash before it appears.
Thanks,
The problem is that neither the error nor the Odin page would stay on for more than a few seconds. Once they appear, the screen would go dark after 5-10 seconds and then the "error" page would load again (after being darks for another 10 seconds or so). So I can never have ODIN or Smart Switch connecting to the device (the drivers won't connect in Windows)... making it impossible to upload any firmware.

Could you take a picture of that error ? I've never heard/seen such thing
Hi, thanks for the help !
The error is this:
http://statics1.grupoandroid.com/up...1850.jpg.d2bb2a8b77e4fba5fc6467f3d1547886.jpg
I *think* I have some direction... here's what I did/found:
- I installed Smart Switch on my Mac, and chose "Reinstall Device Driver" from the menu. Then restarted the MAC
- I loaded Smart Switch, and Chose "Emergency Software Recovery and Initialization". Then chose the "Device Initialization" tab
- Added the model number "SM-A800F" and the device's serial number (which are physically written on my device).
Smart Switch determined the firmware version to be used for initialization, as:
PDA:QC3 / PHONEG3 / CSCH4(XXV)
- Smart Switch asked to:
1. Power the device down
2. Load recovery mode by pushing Power+Vol Down+Home, then connect the device to the MAC and choose "Continue" to start the initialization...
The problem/s:
My device won't turn on at all, if I do not connect it to either the charger or the MAC (which acts as a supply source?) - which makes me think the battery is fully drained ? i.e when not connected at all, it won't power on.
But when connected to either the charger or MAC, it would bootloop endlessly. i.e it will load the "error" page mentioned above, shut down itself, reload again, shut down and so on.
(I have to mention, that when I first noticed the bootloop, I reset everything to factory settings, cleared cache etc, and it still bootlooped on the Samsung logo).
If when it shuts down during the loop, I push Power+Vol Down+Home, it would boot to ODIN recovery page, where I can push UP for the Download page, but it will still reboot and will again load into the "error" page, which will again reboot endlessly. If I take the charger off the device, it powers off and won't load with any combination of button push.
I also cannot just make it shut down when the charger is connected, using any of the possible button combinations...
I wonder:
- Is there there's a problem which prevents the battery from being charged at all ?
What's strange is that the original problem which made me get into this whole issue, was that is was endlessly booting to the "samsung" logo - but when I booted to System Recovery or Download/ODIN modes, it stopped rebooting endlessly and stayed on... it was also showing the charging indication when powered off... the battery was charging well ever since.
- Why would it bootloop when connected to the charger ? is it possible that the bootloader went bad during my attept to install firmware using ODIN ? I know it always went through the boot.img and recovery.img successfully and only got stuck at about 50% when installing system.img...
I think the current bootloop problem began only once the battery ran out of power. But why wouldn't it charge at all now ??? It's supposed to still charge in this state, isn't it ?

Hmmm, the thing is, the battery charging process is actually held on some kind of "mini-boot" OS on Samsung I believe, where the phone boots into a certain state, with that said mini-os to display the battery charging info and this kind of things.
My guess is that you *might* have, or more likely your phone did corrupt the flash at some point for x or y reason.
What I'd do is :
Let the phone on a charger a whole night doing its bootlooping thing. And see from there if the battery would charge.
I'd try another computer with Odin just to be sure something is not triggering the reboot process at some point.
And if all the above fails, you still have the warranty, so beside time, you would not be losing any money..
I'm going to write a long post. But I believe it will help a lot of people having a similar problem.
Long story short - problem solved! but it took much of my nerves (and time).
I'll start with the "warranty". The so-called Samsung "warranty" which basically worths nothing!
Calling Samsung international service center, they "informed" me that I must contact Samsung Vietnam, where I bought the device, although I am not there anymore... Needless to say the local dealer in my country refused to take care of this situation, saying Samsung's warranty is regional based, rather than international... which means, only Samsung in the original country where the device was sold in, are responsible for the warranty (and therefore repair!). I had a chat with a Samsung Vietnam representative, who just kept saying "I'm sorry", and refused to let me sent the device out to them for repair! asking me to "bring it to them", although I noted him a few times that I bought it as a tourist and I am not in Vietnam anymore.... Thank you Samsung !! From now on every traveler in the world will know they basically have NO WARRANTY if they buy any Samsung device in a "foreign" country while traveling abroad!
Now for the solution:
I started by letting the device staying connected to the charger overnight, which didn't help. With the OS now installed, I realize that the battery was NOT CHARGED ! it was completely drained, although connected to a charger for long hours... So, know from now on that if your boot data is corrupted, it may cause the device NOT TO CHARGE THE BATTERY at all. Luckily, my desktop PC could use the device while connected to it although the battery was empty, until the problem was sorted out. I did get a crash on my MAC tough (Log said it was USB related), while using Smart Switch, so one option is that it could not supply enough power to the device to keep it keep working at all, or working correctly... So my suggestion is to use a desktop Windows PC in this case, which can potentially provide more power to a device with 0% battery power.
After scratching my head, and considering removing the front panel for replacing the battery (a very risky procedure) I decided to keep on investigating....
I followed a youtube video who suggests that you should install Smart Switch on a PC, choose "reinstall driver" from the menu, restart the PC, then use Emergency Recovery and Initialization, enter the phone model number in the search box (as appearing on the back of the device) , and once it recognizes the model, also to enter its serial number. Here's the video:
https://www.youtube.com/watch?v=1yXQUFrEWg4
This basically brings up a popup message saying Smart Switch detects a compatible firmware for this device, and is about to download and install it. It then asks the user to do the Power+Vol Up+Home push combination trick + pushing UP once the page is loaded in order to "Continue" and bring up the ODIN Download screen, which worked for me if did that as soon as the device shuts down (in the middle of the bootloop). As I couldn't make it load at all with no charger connected, I had it connected to the charger, and once I saw the Smart Switch message asking to do the push combination, I quickly connected it to the computer using another cable which was already connected to the PC USB port on its other end.
Somehow, I could at last make Smart Switch finally start downloading the firmware from the web, and the device again disconnected (bootlooped), but luckily Smart Switch didn't care about it disconnecting, and kept on downloading the firmware. At about 85% of the progress bar state, I could find the downloaded firmware on the temp folders, which are described in this thread:
http://forum.gsmhosting.com/vbb/f777/samsung-firmware-download-belongs-his-serial-number-2038404/
I had to make sure it wasn't still downloading, and watched the "last modified" state of the file to make sure they are not being downloaded anymore. CAUTION: although the AP was not downloading anymore, I know it was probably not good as ODIN couldn't verify it when I tested it. USE ONLY SMART SWITCH !
I quickly copied the folder to which the app extracted the BL and AP files it downloaded, and finally had an officialy bootloader (BL) image, which I could use in ODIN in order to reupload a correct, "official" bootloader to the device....
I hoped the device won't bootloop in the middle, but luckily ODIN was fast enough to send the image successfully, with a "PASSED" status, and the device booted with a nice "Samsung" logo directly to a System Recovery page!
What I exactly did, was loading ODIN, then loading ONLY the BL file into the BL field in ODIN, having it verifying it, and once verified I connected the device, and as soon as ODIN recognized it, pushed START. It managed to upload the image into the device in a few seconds! It seems then, that the bootloop was not caused by a bad battery, but as a result of a corrupt upload of an AP image through ODIN - or because I possibly was using an incorrect version when I tried to upload an AP files to the device on my first attempt to flash it.
Note that I did search for the correct, compatible AP file, by country and model (on Sammobile) but it didn't' work (stuck at 50% in ODIN) ! so I really suggest everyone TO ONLY USE SMART SWITCH if they want to be sure that the correct firmware is being used, and avoid similar situations...
I then deleted the temp files from the PC (the actual ones which were in the temp folder), reinstalled the drivers from inside Smart Switch (just in case), booted the device to Download mode (WHICH DIDN'T BOOTLOOP this time), let Windows installing the drivers (checked in Device Manager), then restarted the PC, and ran Smart Switch again. I repeated the procedure of loading Emergency and Initialization, entering the model and serial number, having it fully downloading the firmware (again) from the web, and installing the firmware into the device. This time it completed the process, and I finally had the device installing and booting into a fresh version 6.0.1 of Android!
Hope it helps!
Hi all. If anyone could help me out I"d greatly appreciate your time and any advice.
So I got this tablet from my brother, working and all, but Google FRP was on it and he couldn't remember the credentials from when he first set it up. "No worries," I proclaimed like some advanced Android tech, lol, "I'll get it running" First thing, I downloaded the "stock.img" firmware from the only other ONN tablet page. Then SPFLASH tools. Then I plugged in the tablet; holy crap theres instant connection (this is better than ODIN haha). I immediately click the Download tab, load the scatter file, the stock directory, etc and hit "Download" after only a couple of minutes, SUCCESS.
So it reboots.
Oh, wait wait, I did nothing to format the tablet and so I'm just back at FRP.
Back to fastboot.
Open SPFlash Tools and goto format, formal all except bootloader, Start. Now though, as I'm waiting, I look over and my niece is pressing buttons on it, nothing seemed to have happened tho on my PC except I noticed moments before, likely when my niece started pressing buttons out of my view, that the little red bar that normally shows progress turned completely red and filled from 0 to 100 in a split second. I left the device and PC alone, only to get a notification after just a couple of minutes reading:
"ERROR : S_FT_ENABLE_DRAM_FAIL (4032)
[EMI] ENABLE DRAM FAILED!
[HINT]:
Please check your load which matches to your target which is to be downloaded"
**I'm noticing that my PC, for whatever reason, is bouncing between seeing the device as USB Serial COM5 and "MK6***" So when the device bounces is when the connection seems to be losing. I'd be happy to share my output for format if this makes sense to anyone.
The only thing is, I cannot get any screen whatsoever to show up on this tablet. I've tried holding down power, power+vol down, power+vol up+vol down, for up to 30 seconds and yet nothing comes up. It's almost like I don't have a bootloader or anything anymore as the device just kind of seems stuck. Even if I try using the DOWNLOAD tab, I still get the message as above. If I try to do READBACK I get a slightly different message. The READBACK will start and the red bar doesn't fill up instantly but after a couple of minutes I get:
"ERROR : S_COM_PORT_OPEN_FAIL (1013)
[COM] FAILED TO OPEN COM PORT
[HINT]:
1.retry a new COM port (tried switching to another USB with no success);
2.retry a new cable;
3.retry a new device;
4.restart the computer and try again.
Am I missing drivers? I communicate with my MOTO on this laptop just fine because of the google usb_driver, but maybe I'm missing a driver? Or maybe the device is bricked in just a tiny instant of someone tapping a button?
Any help would be much appreciate. Thanks a lot!
