[GUIDE] How to unbrick Acer Iconia A500

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.

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 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

[Solved] Mystery bricked tablet. Black "android systems" screen

I bought an Acer a500 tablet a few days ago not knowing how broken it is.
After loads of research and attempting different techniques I still haven't had any progress.
The software issue:
When booting up the tablet, it goes to the black screen with "android system" at the top and power off/ shutting down in the middle of the screen.
Fixes I've tried:
1.
Since I don't know anything about what operating system is on this tablet, I have been blindly flashing different "stock" (from Vache) versions of HC.
--The android logo with gears shows up, the green bar loads but freezes when it gets 1 cm away from finishing.
--After turning off the tablet and booting it up again, "updating bootloader shows up on the upper left hand corner of the screen. Then a message pops up saying "apk installer: all pre processes complete". Then it returns to the black screen.
2.
The tablet will not go into apx mode (using the reset botton at the bottom).---Fixed. I didn't execute the steps properly. Apx mode works fine.
3.
I plugged the tablet into an older windows laptop and the computer could not install the correct drivers to sync with the tablet. Again also my lack of knowledge. I installed drivers from Acer.com
4.
These two guides seem to be exactly what my problem is but I can't seem to make sense of them:
http://forum.xda-developers.com/showthread.php?p=24531880#post24531880
http://forum.xda-developers.com/showthread.php?t=1572622
This is as far as I've gotten.
Other complications:
--The battery is dead. I have to use it while plugged in by the charger.
--Most of the thread that I have looked at use Megaupload as the source of downloading their files.
--The original owner of the tablet will not help me out. As I stated before, I don't know what version android OS was on here before it was bricked and on top of that the original owner won't answer my questions. As far as I know though, this tablet is not rooted or has anything "non-OEM" installed in it. The story goes that this tablet was bricked when the owner tried to "update" it. Before that, it was functioning perfectly.
-----It looks like Darvis is having the same issue and frustrations I'm having but reading his threads makes me think that this tablet is a dead end.

First off......I hope u didn't pay much for the tablet.
Secondly the guide above looks pretty straight forward but maybe this is one of the ones that has files at megaupload?
I know that the ra recovery and timmydean's files are accessible as I have downloaded both of them.
Maybe someone who has done this previously will chime in and get you the other file if it is indeed unreachable.

I would suggest trying to connect the tab to a Windows 7 PC after installing the USB drivers from ACER. Then check if your device appears in the device manager. As long as you have its UID you can flash the tab from the PC with one of the EUU tools - check my signature on "how to revert to 3.0.1" or TimmyDean's thread which offers an EUU with rooted HC 3.2.1 (it's linked in my thread as well).
How exactly did you try to get into APX mode?
p.s. I have the EUU files if you can't access them from the threads links. I can send them to you.

getting into apx mode
When I perform the steps (hold reset + power for 3 secs then release power); the tablet turns on as it usually does. It goes to the Acer screen, then android and back to the black home screen. My computer responds by saying that it is "installing drivers" but it "fails to install drivers". At the same time I have the DND.exe open and it does not recognize my tablet.
I'm trying to follow the instructions from the root 3.2.1 v4 file.
I can't perform the first step where it instructs me to turn on Usb debugging. The problem is that I can't open the settings by clicking the clock. Nothing happens.
I realize that one complication of my tab is that it will not charge. The battery power is below 15% so none of these fixes might not be effective for me. That might be the ultimate problem?
CyaN1de-
I paid $100 for the tablet. As of this moment I feel like I paid too much.
Thank you both for you quick replies. I have to say that most of the problems that I'm having is because of my lack of experience but I'm learning. I hope I fix this tab soon.

if this dont fix it, i'll give you what you paid for it;0
someone posted a while back that a hard reset fixed the android systems screen error
not sure where you're at now but no harm in trying it
Try using hard reset:
1) Turn off your tablet,
2) Rotation lock s to your left;
3) Press Vol+ (which is next to rotation lock) and power on simultaneously
4) As soon as the tablet vibrates you can release the power on button and you
should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol+ is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.

Thanks for the suggestion but I didn't accomplish anything by hard resetting it. I've done this many times and nothing has changed.
I haven't given up on unbricking this tablet yet and even though it's frustrating I'm learning from the process. If I decide to sell it, I'll contact you Dibb.

i've seen the 2 methods u described but i've not seen anyone else have success with it apart from the OP'ers - seems OTT to me but hey if it works for ya...
I've used timmydeans method ALOT on HC it never failed to work and that includes reverting back to HC from ICS - if it doesnt work for your issue then id be tempted to use blackthund3rs APXFlash Tool and civato's HC_ICS_Bootloader zip to flash a new bootloader and rom package on yr tab - but for the moment we'll run with td'sv4 - if drivers fail to install then believe me, its a good sign
try this:
I know you-ve probly done it but u need to do it again:
reboot everything, then reinstall acer drivers (yeh i know)
fire up ya tab but dont connect to yr pc just yet -as you said you
doubt usb debugging in enabled so we'll try another way around it
run the prgb20.exe it will scan for the new image but not find it becos youre disconnected...thats good....
after maybe 5 -7 minutes of scanning for the new image - it will show a
window "cannot detect yr iconia tab"
and instructions for getting into apx mode - go ahead connect usb put the tab into apx BUT don't click next until....
the drivers will try to install, dont let windows search but let me choose
(off memory) choose device and adb or android ph should show up here
the acer boot/recovery drivers should install...maybe even under USB Controllers
once they do and only when they do click next to put tab into:
acer download mode.......
as i said this is worth a go,,,,how about the update.zip have u tried that.....
else the only other way i know is apx flash....ya still need to get into apx
mode and if u cant then ???? sometimes youll try something over and over
and then out of the blue it will work...you'll swear you never did anything different , it jsut worked this time.....
hope you find some joy

Thanks Dibb for your words of wisdom. I've put it aside for now but I'm going to pick it up in the morning.

As addition to what dibb_nz said - Windows 7 would do the trick - I'm almost 100% sure you'll be able to connect in APX mode with the drivers properly installed. Then use one of the EUUs.
Drained battery really looks like the ultimate problem now because as far as I know you cannot charge the tab in APX mode - haven't tried that. Eventually I would suggest to crack the tab open, remove the battery and charge it somewhere - I don't know alternative ways but...may be another tab or you own charger with proper connector ...
http://www.youtube.com/watch?v=xvXihNIdQ1M
p.s. 15% power ... seems enough to flash through the PC...but who knows - don't waste them and get everything you need before starting the procedure.

no probs m8 hope u have better luck tomorrow
if u wanted to try the EC method i have those files if you want them
good luck m8

So I went through all these steps and the TD's V4 tool finishes updating the tab. But then it continues to the same black, android systems screen. And afterwards the tablet won't connect with the computer.
I am currently downloading the update.zip so i'm going to see if that will work.

do u get on yr tab the big 'PASS' in white leetters or "entering download mode" at all???
think we're beyond update.zip if EUU failed but you can try it -
you can get to apx which is a start - getting a new boot/recovery image on there is the main priority I think...as i posted earlier i've only ever seen a fix for this problem work for 2 people, so on new ground here....
But anyway check out the APXFlash method/walkthru in my sig....all the info is in there and the links to the required files ....do we know if you're on HC or ICS B/L????

I got the word pass; now using recovery mode to flash a rom.
not sure which bootloader I have.
I am using:
Acer_A500_7.006.01_COM_GEN2: http://vacheandroid.com/files/Acer_...1_COM_GEN2.zip
But after it says install from sdcard complete it also give me the message:
E: Can't mount/ dev/block/mm....
E: Can't mount Cache: recovery/log
E: can't mount open cache: recovery/log
E: Can't mount /dev/block/mm...

dibb_nz said:
yes if you're talking about the stock roms from vaches thread, you need the full rom package - you cant just use an 'update' package as they need a full rom to work properly....
for instance my original HC3.2.1 Stock build is 7.014.15_COM_GEN1
and theres no FULL Rom for 3.2.1, so i have to use the HC 3.2 FULL instead
.....Acer_A500_7.006.03_COM_GEN1.zip
Once flashed, thankfully I recieve the 2 small OTA Updates to get up to 3.2.1 again
Another couple of days the ICS OTA d/l'ed and installed with no probs....
is that clearer or am i making things worse????

What I've learned from this whole process is that all of the obstacles I'm facing are due to my lack of knowledge. Thanks for sticking with me Dibb. I can't thank you enough.

I could never get mine into apx mode with the usb cable plugged in. So try that if you haven't. And it is literally hold reset, then press power, without letting up on the reset, release the power button after 3 seconds (use a watch or timer!) then one more second before you release the reset... It does work, but the timing has to be close. It must have a tenth of seconds or less tolerance. Very picky... I've done it on 2 different a500s so far and I am heading to do another tonight. If it doesn't work I'll be right back!!!

Crikey just as I finished typing "....land"
Back to more important matters..... whr u at m8????

None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?

None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?
Or why am I getting the "error" messages stated earlier?

recovery mode???
u need a new boot and recovery image on that thing
the HC EUU based flash arent working even tho u got a PASS on screen after TDv4
So HC based methods arent up to it. You need nvflash/fastboot.
We need ICS with the unlocked bootloader it has access to another level below where HC worked because HC b/l is and always has been locked down.
If ICS cant fix it, I have no idea what will and my offer to buy is off the table!!!!
check out civatos guide and ready yourself for nvflash via zip files in that post or blackthund3rs APXflash tool, with a complete tutorial for using it, all links in my sig.
good luck

Just to chime in with a tip on getting google drivers to work.
When getting any device not recognized, or driver error, generally I go into windows device manager, select the unknown or offending device, update driver, only I choose which driver to use, and ignore the error message where it says "may not be compatible with your device", and use it anyhow.
I get that occassionally when swapping back and forth between devices.
Also, battery not charging and display errors, are usually a sign of EC Power control. So you were on the right track about that. Once you get a rom up and running, if the batt don't charge, then there are some EC flash's you can do from CWM.

Back at it again using BT's nvflash tool. And tablet is still bricked.
I've tried a few different bundles and none allow me to operate the tablet. Everything goes smoothly and I get "pass" at the end of the process. When I go to reboot the tablet, it gets stuck at the black start up screen.
Found another lead: http://forum.xda-developers.com/showthread.php?t=1579490
Sounds like he was in the same situation as I am but has a bit more skills and knowledge dealing with problem solving.

You say you were able to flash roms. So apparently recovery is working OK. Have you tried flashing civato's flexreaper? It has code that will detect whether you bootloader is HC or ICS. You may just be flashing a rom that doesn't match your bootloader... I know I'm jumping into the middle of this, but it's just a thought.
Also, when you did the hardware reset with the rotation lock switch did you get the confirmation that it was, in fact, being wiped?
Failing all that, I'd be willing to take it off your hands for spare parts...

[Q] acer a500 hangs on apx mode

Alright guys so I'm about to sacrifice root for this and just get the ota update and root again.....I've tried reinstalling drivers for Acer and apx mode didn't work tried different downloads for tools didn't work tried a whole new PC all together didn't work.. I've also tried entering apx mode manually and automatically I'm running flex reapers ics rom and whenever the tablet is supposed to go into download mode it hangs and never goes I've tried waiting even after an hour it just a black screen ive tried doing a wipe and reinstalling rom twice any thoughts.....i have no idea thanks
Im trying to get ics bootloader by the way ;-)

The black screen IS APX mode... You shouldn't get anything until you actually start to flash the bootloader using nvflash or the tool created to flash the bootloader - sorry, its about 3am here, I'm at work and can't remember who created the flash tool.....

Hi,
I was fighting the same battle just a other day and got over it with the manual flashing guide by Civato & Co. Found at http://forum.xda-developers.com/showthread.php?t=1622425 (almost at the end of the forst post)
I also used blackthund3r's A500 manager to get to the APX mode and then finalized with the manual way.. So a combo worked for me..

lol then dude go to the development section and click the DUAL-BOOTLOADER thread and get the v4+ ics patched bootloader,
follow civvy's guide in the above post to flash your shiny new unlocked ics bootloader
the new apx flash tool the above user described to you sound like your right path,,, read up on the method and versions before trying anything and always nandroid and keep your cpuid saved and backup digitally and physically (sticky note )
did this 3days ago with civvy's guide and all is great in land of android.

First of all, install all the acer drivers on the PC.
Install the Acer Drivers from Acer Support and the USB drivers from the Android SDK here
Click to expand...
Click to collapse
Then get afterota
and export / save (whatever it says) your cpuid and system info and stuff....there should be a button that lets you save that
next, download a rom of your choice and place it on the EXTERNAL SD card...don't put it in internal storage
then use babsector and follow instructions below
Heres the link to babsector.rar
How to use babsector -
Turn your tab off and put it in apx mode manually. Press and hold reset button, hold power for 3 secs after the light comes on and release it, after another second release the reset button. Your screen is black and the power light is on.
Download and extract the .rar to a folder on your PC
Connect your tab to your PC
Navigate to the babsector folder and click on 501 A.bat
Reboot into recovery
Go to Mounts and Storage and Format System twice and Power Off
Go back into apx mode and run 501 B.bat
Reboot into recovery and do the wipes and flash your rom
Reboot!!!

If anyone else is stuck on partitioning error or something using nvflash or blackthund3r, use this method

blue/pink screen - stuck

Hi all,
I have a bit of a problem.
I had an old Oxygen (?) 2.3.? but wish to upgrade to ICS so after installing the 'official' 2.3.5 was following steps in http://forum.xda-developers.com/showthread.php?t=1420728.
I got up to the bit about installing Clockworkmod. When I tried to go into recovery mode for some reason (I must have screwed something up) it went back into the Firmware update (presumably because I still had the sd card with the 2.3.5 updated on it). It gets through the first step of the update but when it goes to start step 2 it comes up with 'Update failed'.
If I remove the sd card and try to start up normally I get the blue screen.
I can get to the pink screen but I'm not sure what to do from there.
Thanks for any help.
Cheers,
H.

Thanks for the suggestion. How do I see what is missing? I have tried various USB drivers but so far haven't found one that will mount the device. Do I need to use logcat with adb?
Any idea why it will no longer allow me to simply reflash the stock rom?
By the way, the device is the standard u8800 - not the -pro.
Cheers,
H.

Not in blue screen, you must go to pink screen mode(by pressing vol+/- end power when the device is turned off). There you'll be able to see the folder with the system files on pc.

Now I'm confused.
When I connect the phone to my Windows computer (tried XP and 7 in both pink and blue modes), the device does not register. Windows detects the new device and asks for drivers. I have tried different ones but none that I've tried so far will see the device. If someone could give me a link to drivers that definitely work I would be most grateful.
Like I said in my original post, if I leave the SD card in it tries to do the firmware upgrade but fails. Is there no way to 'reset' the phone somehow so that the firmware upgrade will go through? Perhaps downgrade to an older version first??
Thanks,
H.

There is not blue screen mode. Blue screen just shows that the system files don't exist. If recovery image doesn't exist you get a blue screen when you try to reboot to recovery mode. If you cannot boot normally, probably boot.img is erased(or maybe all system files which are on Image folder are erased).
Also if you had flashe an official rom version higher of B518, you probably have a locked pink screen, so it doesn' t matter if you have or not drivers because you cannot access the special partition which has the Image folder with all system files anyway.
Now, if the update proccess of official rom stops or second step(after unpacking proccess), probably a partition on the device is corrupted and the update cannot write to it. There is a special update, which you can flash with the same way as the official rom(put it on dload folder), and maybe can solve the problem. I' ve posted it on another thread here before some time. The filename is: update-160up
try to search the forum and hopefully you will find the thread(which has some isntructions and comments also).
You can try to flash a 2.2 official rom also. Maybe the update will succeed then.

Depending on your model you need to restore its pinkscreen stock files. The boot.img will fix the bluescreen. Heres oxygen's boot.img. Mount via usb to computer*

[Q] Acer Iconia A501 - Frozen @ Acer Logo

Yet another Newb
I have googled / search / read many posts & threads over the past days & weeks.
I had a Acer Iconia A500 freeze @ the Acer logo screen like so many other have had, BUT I managed to fix it last time.
My mate has an Acer Iconia A501 ( so its got a sim card as well ) & its done the same thing.
I have tried the same process as the last 1, but to no avail as yet.
I'm needing some help please guys as I bet its something really simple , but I cant see why its not working for me.
OK AFAIK its all been stock Acer roms & OTA updates.
Processes so far..
Power on & hold down volume + & slide screen lock get this & then reboots
erasing user data .. erasing cache...
Power on & hold down volume - & slide screen lock get this
Bootloader v0.03.12-ICS: starting fastboot USB download protocol
Power on & hold Volume - release power button when it vibrates / starts to boot , still hold down vol button
I have tried the same update.zip file as my last A500 experience , but it got me to the android icon with the spinning globe for hours, left from any where from 40 mins to over night & same basically a lockup. then tried again & somehow got it to almost 90 ish % & stayed like that for ages.
Now I can only get it to see the green android guy for 10-12 seconds before he falls over & dies with the red triangle & black exclamation mark inside it.
I'm not fussed on what rom etc or even stock acer again as I can OTA it back up to last again.
I would just like it to work again & see where I am going wrong...

Anyone able to assist in my error please.
OH micro SD card is formatted to Fat under Win7,
OR should it be Fat32 ?? ( I am going to format with another A500 Tablet & hope it works better )
Also when I go to start it
Power on & hold Volume -, release power button when it vibrates / starts to boot , still hold down vol button
it shows on screen that its erasing data before booting & seeking the update.zip file from sd card etc..
SO it looks like its all doing what it should be , but then doesn't.

Still looking for the reason why this flash recovery wont work.
Using various versions & ensuring all are renamed to update (update.zip file) & messages on booting are the same.
looking for / accessing update.zip file etc etc
Android guy sits there & now I cant even get the status bar below him , its just the guy 10 seconds & dead with his guts hanging out
Any thoughts or a correct file to go with the bootloader appreciated.
Am I doing something wrong OR is it that corrupt its stuffed ???
Thanks to you guru's for assistance

Next instalment
My next instalment on the "unhappy" A501
I have moved my trying to an XP Pro SP3 machine.
I have installed the USB driver package & also the Windows update for the MTP.
I plug in & turn on , windows detects the Acer Iconia A500 & loads into Dev Manager as Acer MTP
It doesn't load enough to appear as a separate drive in the "My Computer" though.
I spose its a small step , but still getting no where.
Please Help :crying:
as I would like to hand this back as I need to move house & it will take some time for me to get setup again to be able to look at fixing it.
Ask for more info & I will reply ASAP

Uninstalled the MTP update , same for the USB driver package & rebooted.
made sure the Acer dir had gone as well.
Installed USB driver pack again & looked at that it contains.. MTP folder & drivers are in there already ..
Still shows up as Acer MTP & nothing in My Computer.
I did see that it shows up with the yellow exclamation mark after a while & then re connects again. ??
IF I start Blackthunders A500 Filemanager using the power button / vol + & flicking the screen lock on/off, I start with Bootloader ver & "starting fastboot USB download protocol.
IS this any help to fix the tablet ??
edit : How do I confirm it has USB Debugging turned on IF I cant turn it on ???

Hi Noel, sorry you got troubs
Your ext sd card should really be formatted via android, although there is a tool for windows you can use called sd_formatter, HP also have a formatting tool, google either one - I have previously posted the sd_format tool "here somewhere" will provide the link if I can track it down.
The drivers are the most important part of getting your tab up and running again.
If you have the Acer ones and the USB ones installed correctly, you should be good to go. In saying that, it can be a real biarch when you're in the position you're in.
Uninstall the acer drivers, reboot. Do not have your tab connected, wait for windows to fully start and its done updating itself or woteva it needs to do lol.
Run the driver exe. If your tab is not booting its hard to tell if usb debug is enabled or not. ANd windows will have trouble detecting it....sooooo......
Go to the root guide in my sig, post #2 download the "babsector file". You will also need to download an ics or jb rom, there is a stock rooted ics or you can use one of 'civato's' Flex roms - I'm still running one of his old ICS ones and it does me fine, I've not kept up with the latest roms, so I cannot help you much with that sorry!
Download your rom and put it on your sd card (if theres a formatting issue we will find out very soon!!!)
Babsector is run via your PC, now, win7 32bit systems work best for this, so if you aint got one, find a mate thats got one! You will save yourself alot of grief by not using win8. Even XP or vista will work!!
You'll need to enter your cpuid so keep that at the ready.
Babsector will flash cwm recovery and install the unlocked bootloader for you.
After running the first bat file, enter recovery and do a complete wipe, (enable data/media option) It has to be a FULL wipe theres no getting around it. And yes, do the wipe procedure at least TWICE!!!!
Once the wipes are done, flash the rom and then run the b.bat file for good measure. As long as you see the big white "PASS" after running each bat file, you're good to go.
IF there is a problem, babsector will output an error....post that and we'll go from there!
Good Luck

Morning dibb
I have the Acer USB driver pack that has MTP files as well, is this all I need or maybe that's the start of my problems ??
( Acer ones and the USB ones installed correctly ?? )
1 of my many issues is that as its not my tablet , I don't have the cupid at all.
It wont start so I cant get it that way , & tried to connect with blackthunders A500 file manager as well but doesn't output any data that I can see / find.
Im thinking I have to flash with an unlocked bootloader before I can do anything - Yeah ??
I am quite happy to eventually go back to stock ICS @ the ends so anything is good.

R u familiar with Linux at all, its the only way of retrieving yr cpuid.
If not, it will be a matter of finding an update.zip that will work 4 u. There is one in the root guide u can try?

Hi
Not played with any Linux before so this might be funny at best to say the least.
the update.zip you suggest , is that the HC 3.1 full ??? (then rename to update.zip) on sd card & try ??

Yep, there's a guide stickied in general for using Linux to get it.
And yep the hc 3.1 FULL. If u get it booting you can OTA all the way to ics, but that's quite time consuming. So root it and install cwm, that will get u yr cpuid. After that unlock the boot loader!!!
I see there's a kit Kat Omnirom, based on civatos flex Rom, gonna give it a spin myself

Hi dibb_nz
with lots of help from JdgM3NT4L I now have the cupid & can get through all of Blackthumders apx flasher up to the 2nd stage of the flashing where its uploading the image file.
it goes into this about 50 % then just hangs...
How long should it normally run for the flashing ??
.

Oh dear, this is not an error u want to see...Would explain the freezing issues. I've never seen a suuccesful solution for the ebt error. Just keep trying sooner or later it will flash....also the tdv4 file has been known to work , you'll be back on hc 3.2 with that but you'll have root and cwm if that's any consolation, lol...
The manual nvflash methods work best babsector or civs nvflash. If it is a faulty chip then even if u do get it booting it won't be a permanent fix.....
See how u go with the other methods k?

See how u go with the other methods k?

Ok
looks like its almost a lost cause..
using civs flasher in APX mode under win7
gets through the start of the flashing to failed executing command 25 NvError 0x120002
command failure: sync failed <bad data>
bootloader staus : Bct Write Failed <code22> message : nverror:0x42008 <0x6042008> flags :0
then it has *press anykey when your A500/501 is in botloader mode
press any key to continue .. so I did anyway
flashing bootloader : bootloader_v8.bin
nvflash started
[resume mode]
formatting partition 4 please wait.. command execution failed cmd 13, error0x120002
failed!
command failure: format partition failed <bad command>
bootloader status: unknown operation <code: 1> message: flags:0
.

When u tried the apxflash tool earlier, there's an option to "dump" yr bct - If u didn't do that try dumping it, and then choose " use saved bct' , sorry dude its been a loooong time since I've had to do it so I may not have the wording exactly right

Ok thanks.
Will try that as well when I try #17 again shortly.
will make sure tablet is connected in APX before I click "dump"
I assume because I get all this way with multiple programs , the CPUID & SBK have to be correct ??
