Hey guys,
it looks like i've got a serious problem. Yesterday, while surfing the Net, i got a bunch of forcecloses (android.media, android.app.widget e.t.c.). I managed to reboot it, but afterwards i got the brick. For two hours the device stayed playing boot animation. I managed to charge it and tooday the problem still exists.
What should i do? How can i do a Hard Reset?
Thank you.

Have you done a paper clip reset ???
Insert paper clip in reset hole lower left of unit.
Should reset unit.
no result.
haven't booted yet. I have left it 4 hours ago and went to sleep, woke up a minute ago and it still playes blue "android" animation. Have tried recovery, a green gui with ! appeared, but in 5 minutes - reboot with some vibration and again... ACER-logo and forever-boot. Should i flash it?
I've got same problem as you, and when i've tried to flash it the software on the Pc asked me the CPU ID, that is very difficult to have and also, if you finally can found it, there's the chance that is not recognized from the software as happen to me.

Try this: put in your sd card the file update.zip ( i will provide a link to you shortly ). Then power up the device to recovery and it should begin a recovery process from sd thanks to the update.zip. When i did it, anything on my tab remained the same: data, photos, apps...
p.s.
from there: http://vache-android.com/v1/index.php?site=files&file=109
I have recently started to update it to the gen 2 (found it on russian servers,can share a link if you want). Again android-guy with "!" on the chest appeared and after a while the device rebooted. It has being booted now for a 10 minutes (again android blue animation). I don't think this is normal. Or is it?

Just a "guess" type suggestion.
Can you install just the update you have on a clean SdCard with you PC then put back into the A100 and try a reboot.
Reboot of a install do take quite a few minutes. not more than 20 or 30 though.
try with the file i've gave you before. At the starting try several combination. Not only power&volume up, also with volume down and also BOTH volume pressed hardly.
should the card be absolutely clean containing only update.zip?
and IS the green android guy with ! on the chest normal, or it's my issue?
Update:
Have flashed it with gen 2 got it with on + volume up button, but still no result. The upgrade was succsesfulkl, but the animation still plays.
Maybe it is because the SD card wasn't empty.

What it means is "he" can't find the update file.
However you are placing it on a clean formatted sdcard is the thing you have to concentrate on.
I wish I had more info to give you.

Lol. I finally got it working went back 3.0 this is the instruction i follow bellow, doing all this and didn't loose any apps or info after going back and update.
METHOD 2 - thanks GamezR2EZ
This is even easier because it does not need your UID. It is just flashing as a normal update but actually it is an older HC version that is rootable by Iconiaroot.
1. Download this package Downgrade_not_stable_zip
2. Extract the update.zip from it and place it on your external SD card.
3. Turn off your tab and then turn it back on while holding Volume Down key. This will automatically flash the update.zip from your SD card.
4. After flashing is finished you'll have unstable Honeycomb 3.0.1 - gives errors and crashes but you only need it to root and install CWM. If it fails to boot try to hard reset your device *.
5. Install Iconiaroot 1.3, root your beast and then install CWM from thor's site(there you can find the latest version) or use Acer Recovery Installer from the Market, or look at the original thread here
6. Boot into CWM and flash whatever ROM you like!

The file linked there is no good. Also the poster removed the link since the mechanism Acer used rendered the file useless once it is installed. The poster claims he found a version on a Russian site. If he can provide a link maybe some goodies can be extracted from it.

Aha, did you use the wrong recovery? I'm gonna take a blind-shot and think that you did. ;/ So maybe you cannot flash CM on it. It is common mistake. - What you are seeing right now is the stock LG charging pre-system. I think you have wiped the image from the system, so it shows you the RAW data instead.
Well, let it charge to 20-25%
Then do this:
1. Unplug the tablet from charger and let it turn fully off.
2. Press and HOLD Volume Down + Power Button.
3. On LG Logo appear, ONLY release Power key, still holding Volume Down. Then quickly press and hold Power and Volume UP also. So now you hold all three buttons. So you need three fingers.
This should take you to "Factory Reset", but when you have custom recovery, you can press Power and you will come to custom recovery. I think you can mount the external SD card and then flash a new recovery. Go find PhilZ recovery in the Original Android Development sub-forum here. You just flash the Zip inside of TWRP. When that is done, reboot and repeat the steps on the top of this post, then flash CM.
Keep on trying the key combo, it is a bit tricky, but it works. While you try and get to recovery, download PhilZ CWM touch and prepare the SD card on your computer, if you have the option.
Good luck.

thanks for your reply.
yes I did use the wrong recovery, as a matter of fact I didnt know which one to use so I choose one randomly
the bad thing I did what u said. and nothing happened .. still stuck at the lg logo and Is not charging anymore...
Keep on trying the key combo. Hold power + volume down, when logo comes, release power, still hold volume down, then also hold power and volume up, so you hold all 3 buttons. But never release volume down.

Here is quote from someone else I found in another place but shutdown the thread without thinking.
I use the download mode to install the original official rom.
1. Download the LG MOBILE SUPPORT TOOL by this link:http://www.lg.com/us/support-mobile/lg-V500-White
2. install the software in computer, Plug in USB cable with computer, Open the software LG MOBILE SUPPORT TOOL.
3. Turn off Pad and unplug.
4. press hold both volume up and volume down, Then plug in usb cable, And then pad is in downlaod mode
5. USB driver will be insatlled automatically
6. In LG MOBILE SUPPORT TOOL, click option---.country and language-OK, then click option--upgrade recovery
7. It will installe original official rom automatically.
8. After about 1.5 hours, The pad will be installed the last official room.
^ This is a quote and now I shut down the thread, sorry, don't know who said it, just got stoked when I saw it.

Go into http://forum.xda-developers.com/showthread.php?t=2551499 and scroll down to downloads.
You are on stock ROM, meaning you wanna go and check in your system settings - about tablet for the software information. Choose one of the three: V50010a, V50010c or V500e. Download the right one for your device. Then a few lines lower, download "Loki" from the link.
Enable developer settings in your Tablet and follow the adb instructions in the thread. This is the TWRP you need to flash a KitKat rom. The older versions will fck up your device. - Remember to root before you begin!

hey man thanks for ur reply.
so far we are In the same page
I downloaded v50010a which Is my devIce then loki zip
but I have no Idea what Is cdm and adb I tried to open cmd and run thoose commands but I getting eroor adb not support something like that.
although I download adb.exe and fastbook and Installed It.
Is It any way to flash recovery though my tablet like goo apps or rom manager ?
thanks.
Go here, http://forum.xda-developers.com/showthread.php?t=2553192
Read first post, donwload and enable developer options on Tablet.
Then download and run the .bat file. Then you get root.
Then you go download the V50010a.lok file and you rename the file to V50010a.img instead.
Then you go to market on phone and search for "Flashify", and you flash the .img in there. (I don't use it, but many people does.)
I recommend you study a bit on adb and fastboot for another time, since if anything crashes, adb is the way to go. Not Flashify. But for now Flashify GUI should be fine. Just remember the root first.
This is the last question I will help you with since all of your questions has been in other threads and you should be able to find them in the forums.

Hello,
This is the third time I've asked you for help. This time it is, it always concerns google pixel C. Everything worked so well. But today, by simply taking a picture, the device turns off and on again on the google logo. Then the android robot with a red alert appears. the word "No command" just below. I can navigate the recovery. But impossible to go into "android recovery" with the menus to apply sideload ota.... I sincerely think it is brick and I'm really very afraid that I won't be able to use the guarantee despite having locked the bootloader before. I was on the official Android 7.1.2 software. The adb and fastboot commands detect the tablet. But I can't unlock the bootloader or flash... I have no idea what to do, I could use your help please!!!!!!!!

Have you tried this?
"Turn off GOOGLE PIXEL C. Press and hold together : Power Button + Volume Down until Logo appear at LCD screen. If we see the menu at LCD screen, choose Wipe Data/Factory Reset with Volume Button to select and use Power Button to ok or enter."
Are you sure I can do that? Because I had downgraded Android from version 8.1.0 to 7.1.2 because I had a problem with 8.1.0. Therefore I had unlocked the bootloader etc.... So the data had been erased! If I do a wipe data/Factory reset will it work at least at 90/95% ? Despite having only installed the Factory image (without OTA) can it work without doing a bootloop or other...?

Well, I tried and I always fall back on the page with the robot and the inscription "no command" just below. I'm sad ?
If the bootloader is unlocked you maybe have a chance by install TWRP and then install LineageOS 15.1 (wich is much better than stock).

Tell me, the OTA file is used to apply an update, right? Because I tried to do this manipulation but by downloading Exactly the same software and it didn't work. So if I try with a more recent version of Android, it should work, right?

How did you fix it
I had the same exact same fault in December and couldn't work out how to fix. I thought my tablet was just a paperweight now but would be so happy if i could fix it.
do you have a link to the method you used or can you provide more details on how to fix?
what do you mean by the OTA image had to be installed?
Each time I tried to copy the image from my computer to the tablet it failed.
would be grateful for any help.
thanks

Hi, if your device is a C pixel, you can try to check it out here: https://developers.google.com/android/ota
To sum up, my problem was the following: suddenly, my tablet could no longer boot on android but on the page where the robot was displayed with a red panel and the indication "no command".
And the solution was the following: being on Android 7.1.2 I had to download Android 8.1.0 for the "update" to work. So I followed all the steps indicated by the site I provided you. That is, having Fastboot and adb working, then putting the.Zip file of your android in the same folder as adb and Fastboot. Then you follow the different steps shown on the site to download the ota image. My explanation is not great so if you have a question about something specific let me know. And if you can send screenshots of your worries it will help.
Good luck with that!

My unit is a PbA ES7815, which I believe is identical to an Erisin ES7815. The original MCU was MTCE_LM_V2.88, which I upgraded to MTCE_LM_V3.01c without a problem. I recently saw MTCE_LM_V3.30 was available on Yandis so I downloaded it and did an MCU upgrade.
The result was a blank screen. I can't boot into recovery with the reset button and on a long press of the on/off switch I get a LED flash, but that is all I can get it to do.
How can I recover back to MTCE_LM_V3.01c? Sorry if this is something I should be able to find..

Hi, you will need to upload older firmware via ST-link. There is some tutorials on the internet, search for "PX5 bricked MCU fix".
