I just got from a friend an Acer Iconia a500 he says that is bricked.
I tried this method: http://forum.xda-developers.com/showthread.php?t=1572622
But I can't continue because I don't have ADB access, what should I do?.
Thanks for all and God bless you.
EDIT:
I got everything to using the secret APX mode, but now is still everything the same the Android System is still there and not charging and not touchscreen...
Go to the bottom to see how I solved this lol...

If your tablet Iconia 500 (ONLY ACER ICONIA A500) went crazy, and present the next symptoms (Yes it has flu...):
-flu
-Android System icon
-Doesn't want to charge (20% / 15% 12%).
-TouchScreen is not responsive.
-Always when you turn it on says Shutting down and never shuts down.
-In case you're using ICS shuts down immediately without even make you see.
The solution is the next!:
1. Download this file: http://www.4shared.com/archive/zyP91E0C/root-321-V4.html (This is the file to put recovery in case that you don't have it).
2. Extract all the files in any folder, it doesn't matter where you put it.
3. Go to Image Folder and rename the recovery to: anyname.img.
4. Download any of the lastest recoveries for Acer Iconia a500 (it will work believe me lol).
5. Put the recovery in the Image folder (Ex. Iconia/root-3.2.1/Image/) and rename it to recovery.img
6. Now open with Administrator Rights DotNetDetecter.exe
7. Continue, continue and continue.
8. If you have ADB Active just put it and it will install it. (If you don't have it just go to 8.1)
8.1 Shut down the tablet completly, connect your USB Cable *micro* (Tablet-Computer), take a paper clip and put it on reset without release it then press the power button and count until 4 or u4ntil you hear the sound when you plug something into Windows
8.2 Now your tablet is in APX Mode and the Acer Utility should now work.
9. Put your UID with a 0 in front of all the numbers (if you don't have it go to secret step).
10. Now let everything work. After everything is done you should have recovery now.
11. Press down volume and the tablet will take you to the recovery.
12. Download some ROM 3.2 or ICS 4.0.3, install it via recovery.
13. Download this file: http://www.mediafire.com/?9svnvdk982sxrw4
14. Install the version you have choosen via Recovery.
15. Voila! Your tablet is revived right now
Press thanks button if this helped you =D
SECRET STEP TO GET UID (IS NOT SECRET THOUGH... lol)
Just go to USB tools and use USBdeview, and is done... (Remember to stay in APX Mode)

Acer Recovery from the Market should have the most recent RA Recovery, and the original GPL compliant CWM recovery.
Or if you already have the original CWM, you can get the most recent RA Recovery here. Just check the threads for the flash files.
http://forum.xda-developers.com/showthread.php?t=1459821
For CWM you will need to go to tegraowners.

Problems with opening up settings to turn on usb debugging
Hi Travisantonio,
I have a question:
Did you have any problems opening up the settings when you were on the black "android system" screen?
My touch screen is completely unresponsive at the moment.
Maybe I didnt read or understand everything but with my tab USB view didnt give me my ID or it wouldnt work. Got into ADX mode but couldnt get things working. Tried ADB to list devices and would never list anything. I heard my computer beep when I would hook it up but couldnt really do or complete anything. I couldnt get the DOTNETDETECTOR (PBJUPRADE_ to work. Tried A500 APX flash utitlity. Tired nvflash and falied. Guess I should list more information but at this point I tried so many things to recover dont remember the order I did things. I originally tried to upgrade to a Rom but all things failed and actually not sure what ever got completed. Only thing I could tell my tab did besides black screen was the power button either was white(some type of one) or orange.
This helped me to recover my bricked Acer 500 tablet after a failed ICS upgrade. The Acer update seemed to go okay, but on reboot it froze at the Acer logo and had an error in the corner. Every reboot or button/reset resulted in this. It would not recover or do anything else. I was able to get the USB device ID /serial number using the USB deview 64 program in the usb folder. There were several entries for the tablet but only one had a usable number (bottom right line at the end). Then the tool wiped the tablet and reloaded 3.2.1 and booted to factory new. Thanks for the instructions and to all the other XDA-ers for the tools. I am now on ICS properly.
Trying to recover a bricked acer a500, I just have a black screen on boot with no boot logo, vibration or letters or words on the screen
trying to enter recovery/update mode doesnt work
Im up to the step where is says put in your UID into the program
Just go to USB tools and use USBdeview, and is done...

I did this and found the device but where exactly is the UID located?
looking at other threads, the serial number is the UID however the serial number entry is blank for this device

this method is total overkill for your situation....
how did u get yr tab like this???
if u have total black screen - is the power button lite on?????
what bootloader version are u on
have you had a custom recovery on there
to get your cpuid follow the first link to a guide in my signature - you need to follow steps in the guide if you have any probs then post in the guide thread
the previous owner said he tried to install a custom rom and I think it crashed and this is the result
the power light turns on (white)
if I just power it on, the backlight turns on however its just a black screen, nothing else happens
apx mode seems to be the only thing working right now, I thought this method would be my only chance to get the recovery mode working again
I dont know anything else about the tablet, bootloader ect...

ok thats cool, apx mode works!!!
well try this first - using hard reset:
1) Turn off your tablet,
2) Rotation lock on your left;
3) Press Vol Up closest to rotation lock and power on simultaneously
4) As soon as the tablet vibrates you can release the power button and you should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol Up is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
otherwise plan B!!!
do u know whether tab was running HC or ICS?
u need some package files and a flash tool either apxflash or nvflash
if u start the tools and then connect your tab via usb cable to your pc
there are links to guides in my sig
my cpuid guide shows u what u need and where to get it, info about your cpuid too and drivers - altho you wont need to worry too much seeing as youre in apx
civatos guide has all the links to the packages and all the info you need to patch the bootloader, then you can flash one of the ics roms and youre all good!!!
the process is simple enough - but if you get it wrong it can be frustrating as heck!!!!
tried that method, get no vibration, devices just turns on to the black screen like normal
the only problem right now, I cant retrieve the uid
adb
when I type adb devices, nothing shows up
A500 manager
tried to the use the uid retriever tool however it just stays blank, same for the bootloader
it says it detects the A500 in apx mode
usbdevice view
shows no serial number for this device
I see there is a A500 motherboard on ebay (cant link to outside links...)
"Acer Iconia A500 Tablet Replacement Parts - MainBoard - 32GB MB, H6000 001 PBJ20"
"Complete with Android 4.x installed, 32GB memory and ready to install and boot."
could I get that and just replace the whole mobo and it will work fine?

OK just clarify - black screen, that is, nothing at all displayed AND Power Light ON??
IF u r in apx mode then
U have a couple of options
EUU flash back to HC 3.2.1 or
apxFlash to ICS
Everything you need for doing this is in my cpuid guide link in my sig.
open apxflash tool do not connect your tab Yet
Go as far as the enter apx mode
Now connect your tab to yr pc
Windows should install apx drivers
Once installed. try clicking blue arrow first
If u don't see the do u want to flash window then
You'll need to click on the "enter apx mode " button instead then
Click blue arrow
Hopefully the PC and tab are feeling pretty friendly and decide to take each other on
The tab should flash the bl and install recovery.....u should be good to go from there!!!
EDIT you can try cmd prompt on nvflash folder
Run a500.bat or.bat file that should kick you to bootloader mode
its really important that your screen display something in white letters!!
Entering Acer download mode OR
Entering apx mode
The flash will fail if u don't see something like this. This holds true for all methods

Wayyyy outta my league m8. Sum1 else will know....
yes, its just a black screen, no vibration, no boot logo, no letters or words on the screen, backlighting for the screen is on, and the power light is on
when I press the blue arrow in a500 apx flash tool it asks me for my SBK, going to that generator site it then asks for my UID which I cant retrieve

if you do not have your cpu id and
if you do not have access to adb and
you're stuck in apx mode
then things are looking grim.....
the only way to get into your tab without yr cpuid is fastboot
but you need adb working for that
someone else was stuck in apx mode a day or two ago, try a search...maybe...
I'm sorry guys I was a little off of this thread .
I will be glad to help you guys to get your UID or any problem that you have even though I don't have the Tablet anymore.
Thanks for all and God bless you all.

There is no way to fastboot the tablet in that mode, the only way is to get the UID and then decode it and NVFlash the Bootloader after it is done then put ICS or HC and the EC_ROM files and the tablet will be working again.
I'm gonna throw in the towel and just buy a new mobo for cheap, it seems im screwed without the UID and cant retrieve it either
I wish the previous owner would have gotten the UID beforehand
thanx for the all the help though

Hello,
I am another unfortunate user who has bricked his tablet. I installed Jue11 Ram Manager Plus and it asked to reboot my tab. On reboot it was bricked, flashing the android logo and not going any further. I have tried everything listed on the site to get my CPUID to no avail. have followed all instructions including trying to retrive using Ubuntu Linux, A500 Flash Tool, (which tells me it is in APX mode but returns a blank serial), NVflash gives a device not found. Any help? I am technically saavey on PC, Windows and the like, but fairly new to tablets.
A little more info, using A500 Manager it reports a500 in APX mode then acts like it is retrieving the serial but comes back blank. Nvflash reports device not found. Using Ubuntu gives errors but reports all needed packages are installed, (not a Linux Power User so could be an ID10T Error on my part).
Please, I appreciate any and all help.

if u meant rom manager - our tab isnt supported, you'll need the patched BL before u can install a custom recovery
if nvflash is reporting device not found then check your data cable and/or that the acer usb boot recovery is installing from apx mode. You may need to manually install it by pointing it to the acer folder in program files/data depending which win OS u have...
try that and see how u get on...

Hey,
when I try to get into the recovery (with Volume and Power Button) the a500 is saying "secure boot: image SOS checksum fail".
I got my correct UID and the corresponding SBK.
I read all of the help threads but no described way works... :crying:
- My bootloader is: 3.01 (not clever I know)
- Build-Number: FLEXREAPER-R12.5 base: A500_1.031.00_ww_GEN1 (still booting and working but very unstable)
- Kernel:2.6.39.4+
- Andriod Version 4.0.3
I tried:
- APXFlashTool (hangs on stage 2)
- "EUUs_SBK_Acer_A500_1.016.05_COM_GEN1" (says I need a newer Version?)
- I tried to install a recovery over Acer recovery (it installed recovery but at booting in recovery again secure boot: image SOS checksum fail)
So please XDA-Devs help me before I play Frisbee with the A500 :laugh:
When using the euu, don`t connect your tab until there comes a popup how to get tab in apx mode. This can take up to 5 minutes. Then connect it, enter the cpuid, and it should work.

I give it a try tomorrow... hope it works. Will write my experience
one step further
tetsted it like VelosCohagen said and comming one step further... Now I can type my UID in the EUUs updater and start the flashing process, but after 2-3 minutes when the white text "entering acer download mode" in the left-top corner appears, it stucks there. The updater breaks up with the flashing process and the tablet stuck at entering Acer download mode
So, any help?
thanks, Tobias

Hi all, yes, noob here.
I has successfully rooted and put ICS on my A500 with Skrilax_CZ`s bootloader V8.
I decided to go back to stock, however ended up with HC running on an ICS 4.0.3 Kernel (2.6.39.4+)
I made the stupid mistake to try to flash again with a "stock' ROM, and A500 is now is a 'dead like' state.
No Recovery, or Fastboot - Turns on but tablet screen blank and only 'life' is when connected to PC via USB it does show in control panel/devices as "Acer Picasso USB Boot-recovery driver". But no driver letter in explorer.
Pin hole reset/Power doesn't do anything either
The only thing I have managed to do is use DotNetDector.exe, do the pinhole/reset, enter CPUID and the A500 starts, vibrates and shows ACER on the screen with 'Entering Acer download mode'. Hoewever, DotnetDectors then shows "Sorry upgrade process failed"
CPUID, SBK number are known.
I have clearly screwed it up! and wondering if this is recoverable. Any help/guidance welcome.
Fixed
Doh!
OK I fixed it myself, I tried a different a500apx file and it started working. Used;
V8-Thor_1.7.3_recovery.a500apx
Thx all

Hi,
I have an Acer A500 that I'm trying to resurrect after my son tried to root the device. I'm new to this and have checked many sites in search for a solution to this issue (if possible). I'm not sure what all my son did to this device so please bear with me. After reviewing several posts I find my issue unique where as some members may have simular issues I still have not been able to isolate my issues.
The issue: The device is stuck in APX mode with a black screen.
1) The Power Button does illuminate when powered "On" but the screen is "black". There is NO vibration when turned on.
2) The Battery life is good on this device.
3) When the device is powered "On" and connected to my PC the "Blackthund3r A500 manager" display "A500 connected in APX mode. Please Install drivers!"
4) Using Ubuntu I was able to get the "CPUID" and with "SBCalc_v1.1" I was able to get the "SBK".
5) Performing a startup utilizing reset button and On button has no effect
6) Going to "On" with the Vol + pressed has no effect
7) Using "AfterOTA 1.09" on the first "Info" tab under "Tablet Information" it displays Driver "OK driver installed", under USB it displays "ERROR - connect USB cable and enable USB debugging". Everything else displays "waiting for connection". Pressing "Reconnect Tablet" has no effect.
So far that's all I have been able to do to this unit with NO success. I welcome any feedback on this issue.
bricked tablet
best bet is to use babsector
it will install recovery and unlocked bootloader and format all the partions back to default
then you can flash updated recoveries roms etc, from there

Thanks for your response. I'm not familiar with that with that program. Will it work even though the other programs show the device not being connected? (I've Used several USB cords with the same result). Where can I get that program?
you will need to install the acer usb drivers to your pc
if it's win 8/10 then you will need to first disable signature enforcement
http://forum.tegraowners.com/viewtopic.php?f=10&t=2196
babsector is a simple forum search
I complied with the driver settings and still no joy. The device stays in the APX mode and nothing seems to helps on connecting the tablet to the PC. Is there any script that will manipulate the tablet setting for connecting using Ubuntu?
can you give the steps you used to obtain the cpuid? im stuck with a black screen. have ubuntu installed on a virtual system, when i run the command for apx the file that comes back does not have the cpuid.

You can recover the CPUID by following the instructions at this link http://forum.xda-developers.com/showthread.php?t=2096826

thanks for the reply. i was already trying out all of those guides. it didn't work at first but i changed a few lines of coding and it worked!!! i was using a 32bit ubuntu, made the suggested changes and also added a different line elsewhere. if anyone needs the apx.c file i used with all the changes already made. let me know.
