thanks to everybody, as i described in another post i bricker my iconia trying to downgrade from ics to 3.
i've read a couple of posts, i've found tolls than could give me achance to recover but i don't know my serial number.
so first question i ask is: opening a ticket with acer assistance they show as serial number this:
XEH6LEN0021140E7131500
i tried to take apart the last 15 characters and add a 0 but no luck.
is there any other solution ? is there a chance to get somewhere an update.zip signed ?
sorry if i asked stupid questions but i'm a noob and quite desperate.
i know i did something stupoid and i won't get upset if someone reminds me this ....
thanks to anyone that reads, cheers and sorry for bad english
no that's not it
r u back at hc or still trying to get back
check the guide in my sig to get yr cpuid. haven't failed 2 find one yet
many thanks.
i readed your guide before bricking, i tried looking in pc system (but i had only an eleven digit number) and i tried with a terminal app on the tablet, but it didn't like one command.
now that is bricked i don't know how to get it.

Things are looking grim if we cant get your cpuid
I take it you don't have a backup with the uid.txt file somwhere on your computer maybe????
The 11 digit number is a small hope as it suggests you're on the HC Bootloader in which case yes you are able to recover using an update.zip
go to this link and follow METHOD 2
the update zip you have to d/l is UNSTABLE and tricky to use
but all you need it for is to ROOT (with Iconia Root from the market),
and install CWM (with ACER Recovery Installer also from the market.)
Once you have CWM make a backup and get your uid from the text file in the backup folder -
make a copy of it AND KEEP IT SOMEWHERE SAFE!!!!
if you have problems booting the UNSTABLE rom you have to do a hard reset (see below)
You may also need a rom to flash seeing you dont have a backup to restore
you can give hard reset method a try on your bricked tab first- dont think it will work - but u never know.
1) Turn off your tablet,
2) Have the Rotation lock on 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 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.
Good Luck
many many thanks for your help, i don't know how to thank you enough.
i tried the hard reset, but i still get the boot verified failed ...
the update.zip file in method 2 is the one i used to brick the tablet.
i tried again, the message i get after the flash is:
Not legal !!!!!!! abort
Warning: The blob package is not official ~ Abort!
followed by the red Boot verified failed.
maybe i could try another one, but i don't know where to get it.
i tried to read how to extract one from an entire rom but it's a bit tricky and my antivirus reports the tool as a trojan.
i'll try to look around, then i think i have to send to assistance.
thank again !

yeh i thort this was sposed to happen the not legal thing
then u do the hard reset
when u do the hard reset does erasing data erasing cache show up
r u sure you're completing the whole process???
i get both the erasing data and erasing cache, but no result.
i disabled the antivirus in the pc and was able to run the update decrypter from thor topic.
now i need something to give him.
could you please tell me what to do ? i downloaded the file root3.2.1 from timmydean but i don't know what file to use, since it's not a zip file but there are many files and folders in it.
again, many thanks and sorry for bothering

....first take that update,zip off your external_sd card...you dont wanna be fixing the problem and then borking it again cos the update.zip is on there
timmydeans should be a zip not sure where u got it
ive attached a pic of the folders in my timmydeans v4 should be similar,
theres a readme and pdf in there with all the instructions but basically
1. run test.cmd just click on it - you have yr tab connected to the pc
2. the window should say list of devices attached followed by yr CPUID
You HAVE to get this to show up the rest of the process wont work otherwise.
post back with what happens
again, thanks a lot.
i think there's no way to get the id.
if i attach the tablet with the red message it isn't recognised by the system.
if i do it using the paper clip it is recognised as ACER Usb boot recovery driver.
in USB deview, which column do i have to look at ?
meanwhile, i picked Acer_A500_0.000.00_1.013.01_EMEA_GEN1_1300336887417_befd43a1.zip

just my input... might be wrong, but every tidbit helps.
In USB Deview, I believe you look for android.bootserial if it's the same as we run dmesg from ADB, Not sure but check it. Never ran USB Deview before.
Also, one of my russian colleagues said that everytime you connect the USB to the PC, windows keeps a record in the Windows/temp folder for the device ID. If I can find the PM in my mail, I'll post his info again. Theory is, you may be able to get it from temp, so don't clean your temp folder.
ok, under serial number column there is only the 11 digits, so no way.
i'll do some trys using zip files of official roms and trying to get an update.zip working, if i don't get results (as it'll probably happen) i'll give up and send it to acer assistance.
you were very very kind, thanks.
are you taking on the next shift moscow?????
what do u think if he cant get his ID and an update.zip wont work??

Yeah, I'll take over for awhile so you can take a break.
Keep in mind I'm bouncing back and forth between baby and Android.
Yeah, you're close to being fubarred if you don't have a UID and running ICS Bootloader (hacked version). But not totally.
INFO: I couldn't find the PM from my russian friend explaining how he found his in the Windows/temp folder, as some strange named temp file. Mainly because it was through ATG site, which is no longer there anymore.

Yeah, looking at your image, it seems to show your current UID under ICS. This is both good and bad.
Good, because you should be able to go to Civato's Bootloader thread, and convert it to SBK, then NVFlash a new ICS bootloader and recovery. Then install an ICS rom.
Bad, because that number will not work with a HC EUU, or even running the update.zip from the SD Card.
In theory, the SBK generated is the same for both HC and ICS UID. At least in my case. One would think Vach could reverse the process to generate a HC UID from the SBK. In theory.

Yeah, flashing bootloader the manual way can be a bit confusing. It involves setting your tab to APX mode. Press and hold the pinhole reset, and press and hold PWR. Hold PWR for 3sec, release. Then release the pinhole 1 sec later. This puts the tab in APX mode. Display will be black, but PWR button is on.
Check this:
http://forum.xda-developers.com/showthread.php?t=1522384
Download the package and extract to a folder on your C drive.
Then go to Vache's site (link in the thread) and convert this number from the image you gave.
11405915515 and generate an SBK number
Connect your tab in APX mode (you should see widows show some connection when you do this about download or apx mode) if not, you will need drivers. You can always check device manager for APX mode when connected.
Run the file you downloaded as in the thread instructions. Do this through a CMD window (command window). Usually you can hold SHIFT and right mouse click and select open CMD window here.
Paste the SBK when asked (right mouse click on the curser)
Hit enter.
If it works, you get a PASS when finished.
If not, it will tell you SBK not good.
It's worth a shot anyhow.
Now I'll be gone for a couple hours. Baby needs Park in the buggy.
many thanks.
i tried but no luck, i receive a USB write error.
i tried for the second time to open a ticket at acer assistance.
first time they said they needed more info.
this time they suggested me to hard reset.
i'll try for the third time, it's annoyin i have to send the tablet and wait for i don't know how long to get it back and how much i'll pay for this (maybe 50 euros ....).
thanks for everything and have fun with your baby !

Well as long as we have ICS OTA this thread seems to be less needed. Anyway, I'll leave it this way in case someone is stuck on HC 3.2 without root and without being able to update to ICS. How to get root on your stock ICS, look here or here
__________________________________________________
If you’re reading this may be you’re stuck with a 3.2 OTA update without ROOT privileges on your A500. This tutorial explains how to revert your OTA 3.2 to 3.0.1. Original article for those of you who speak Russian here
Thanks to begemot666.
These methods could be used to unbrick your device i.e. when boot.img and recovery.img are corrupt.
METHOD 1 - thanks, vache
It is best to use a PC with Windows 7 on it. Most of the problems reported seem to be XP related.
1. Download and unpack the archive provided by vache here - for Firefox rightclick and select "Save link as".
MIRROR
2. Get your UID (without it nothing is going to work). How to do that – read sc2k’s itsmagic thread. Enable USB debugging on the tablet.
3. Edit the file CPUID inside the extracted folder with a text editor - you have to change this line with your UID number but you need to add “zeroxzero” in front of it, example: if your UID is 37c7040425ff0d7, at the end it needs to look like 0x037c7040425ff0d7.
Save the file.
4. Connect your tablet with the PC.
5. Run PBJ20upgrade.exe as administrator and follow app instructions. USB drivers are provided with this archive and the app installs them automatically according to your system.
6. After driver installation the app scans your tablet and it will show version number of your current firmware and version number of the firmware that is going to be applied after restoration. Follow all application instructions. Tablet will switch to APX mode with ACER logo on its screen and on your PC you’ll see the progress bar of the process. Before the beginning of the flashing process the app will ask you for identification number. Here you enter your UID which you have placed in the CPUID file with a zero infront. Example: 037c7040425ff0d7
Below are screenshots from the EUU app that's used to downgrade to 3.0.1
The whole things takes 10 or more minutes so be patient. Then you’ll have HC 3.0.1
All data on your system and data partitions will be lost. Storage will remain intact.
7. Once on Honeycomb 3.0.1, install Iconiaroot 1.3, root your tab 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
8. Boot into CWM and flash whatever ROM you like!
METHOD 1 update: You can use timmyDean 's modified and tweaked EUU tool that will flash directly a rooted stock 3.2.1 ROM:
http://forum.xda-developers.com/showthread.php?t=1307539
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. Additionally method 2 leaves your data intact and you will be able to backup your apps after downgrading with tools like Titanium Backup. Thanks heldc for pointing this out.
1. Download this package (named "downgrade not stable"). mirror1 mirror2 mirror3
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 tab 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!
GOOD LUCK !
* How to hard reset your Iconia A500
1. Turn off your tablet
2. Place the screen lock button on the left (red not visible)
3. Hold Volume UP + Power button
4. After the vibration, release the power button and toggle the screen switch few times left-right until you see the following lines appear on the screen
Erasing Userdata...
Erasing Cache...
You can now release Volume UP button.
5. In the top left corner you'll see formatting has started.
6. Tablet will reboot
downgrade from stock 3.2 now possible ...all right !!!!

Have no idea, my friend, check again all the steps and if the usb drivers are properly installed.
Maybe it could help : EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
You can post it in 4PDA.ru.

Will try this at home.
edit:
I'm following what says on c2k’s itsmagic thread and ran the batch file (01_backup.bat) but my tablet is not rooted.
Using the manual method in getting my UID, how to execute the "dd"?
Manual method:
1. Get your UID (= USB Serial number, has up to 16 chars) (see at the end of this post how to get). If you brick your device and do not know the UID, you are lost.
2. Backup all partitions (except cache + data) with dd:

I apologize for the stupid question, but it's better to be sure before doing something wrong.
I have an A501, I suppose this procedure is still valid, but I have to skip the point where the product name is changed from A501 to A500.
It's correct?
thanks

I've exactly the same problem, with the 2 methods...
Edit : I finally found the solution : if the program says "UID is incorrect", you must add a 0 (zero) in front of it - for example, if your UID is 280404412345678, you must write 0280404412345678 - and it works perfectly !
Thank your very much !!!
I wonder if one of the devs on here who are smarter than myself could investigate this further and maybe figure out enough from it to come up with a root exploit for 3.2? (seems like it manages to bypass the security of the bootloader to go back to 3.0.1, so it seems logical the same exploit could be used for a direct, and possibly simple, root?)

Appears that you have to put a 0 in front of your UID in the last step (wasn't listed in the tutorial, but their example shows it)
On a side note, I've done that, and it claims to be doing the upgrade, but my tablet screen went completely blank (tutorial says it should have the acer logo) and the progress bar is also blank (not moving at all in 10 minutes now)... not entirely sure what's happening, but I have a feeling not much is working right...
The 2nd method worked for me. FYI if you've ever backed up your rom with CWM your UID is in a txt file in the folder of the backed up ROM. Just omit the 0x at the beggining of this file and copy and paste that when it asks you to enter your UID but use the whole UID you find in this file when copying it into the CPUID.txt file THANKS SO MUCH!!! Im now on 3.01 and ready to root/flash this sucker back to my backed up ROM>
I have now tried both methods without any success
Method 1 can't see the tablet, it tells me to do a pin-hole reset and click "yes"... but that just takes me back to the same slide.
Method 2 gets all the way to flashing the image, however the status bar never moves (have left it for 2 hours) and the tablet just sits at a blank screen (not the acer logo as the tutorial says)
I tried reflashing the stock rom, factory resetting, clearing the cache, and trying again, all with exactly the same results.
I'm still stuck on stock, unrooted, 3.2
And the worst thing is, with so many people having success with this, it's likely to become the "official" way of rooting 3.2, leaving nobody any incentive to find another way, and me stuck without root
My screen also went completely blank but it still worked and booted into the Acer logo when it was copying the ROM to the tablet with a message of "entering download mode" or something like that in the upper right corner. Once it was done flashing it had in bock ASCII art letters "OK" above the acer logo and then rebooted.
I'm guessing that it didn't take over 2 hours, and that you had a status bar on the computer doing something though...
Okay... so the other day in class I was thumbing through the intrawebs and noticed the leaked ICS had came out for the A500... I tried flashing the ROM to my tablet, thinking it would be a cinch if I just followed the directions. No go, just stuck on Android boot logo. That's fine and all, made a back up with CWM (which i think was my initial problem with the ICS version.. correct if I'm wrong please,) but... my back-ups check sums were mismatching for everything. Couldn't get them to match and couldn't figure it out so I decided to just flash root stock version back on to the tablet and go from there using my titanium backup.
I flashed, and bam... vibrating black screen, no CWM recovery anymore no matter what I do. I've been using the SDK manager / ADB terminal thinger / EUUS Acer Iconia Tab Software Upgrade Utility. I cannot for the life of me find my CPUID, or at least the RIGHT CPUID. I understand to use software to find it but I don't think my tablet is giving the correct info, or something??!?! When I run adb devices in CMD in the platform-tools directory it doesn't list any devices available. If anyone could help it'd be greatly appreciated. Could possibly upload a screenshot of my usb devices with the USBdeview software?

To get your old uid number, look in one of your cwm backup folders on your SD card.should say uid.txt.
Then you can either use the photo tutorial at androidtabletgeeks.com, or there is text instructions here at xda.
Also, sounds like you may need to load the a DB drivers for your tab.
Help ME!!!!!!!!!!!!!
I've got a similar problem. My A500 are with the Boot "Verified Boot failed" and no way I can make it work again. He was with the ICS ROM'm trying to make it back to the Stock ROM but I can not. Please Help Me.
Hmm...

Okay, that got me started in a good direction I feel like. The only problem is that CWM made them all "*.img" files. There is a "system.img", "boot.img", and "recovery.img". Which one should I be trying to tear into to get it? And I'm pretty sure I have the adb drivers installed, or at least my device shows up in my device manager when I put it in APX mode, and I've downloaded the USB recovery drivers from the ACER website, along with other drivers that people have suggested.
Thanks for your quick reply! Hopefully this gets me somewhere, if you have any more suggestions on where to find it within the filesystem / *.img files let me know.
** Also a "data.img"... didn't want to leave the right one out on accident haha.**
Still nothing...
I've been trying to go through the old CWM back up .img files, but the only one I can even open and extract is the system.img which from what I can tell, has nothing to do with the CPUID. Next I started up a virtual ubuntu to try ADB out on there, same results. Even changed the vendor ID to the one given to me by lsusb, still nothing. I'm out of thoughts on this... I'm burnt out on trying to get this to work.
When I opened up usbdeview, I saw an old version of my Acer Iconia tab when it was actually working. Used that serial number and it made it through to where it said it was upgrading, but then sat/hung overnight. didn't move or make any progress so I unplugged it so I could go to class and keep working on it... now that cpuid doesn't work either.
Is my tablet a fancy paperweight now?
A500 Reborn
People,
I managed to make my A500 back to work with an update file, but forum cannot permit to put the link here. Take out the spaces of the link below:
www . fileserve . com / file / 2HUVP9D / update(ok) . zip
Rename the file to "update.zip", then save this on Sdcard and Boot the A500 with Vol - pressed.
Worked for me.
so..

Did you have a recovery that you were able to boot into when you did this? Or does holding vol - while powering up install the update.zip? If you used a recovery manager it's not going to help me at all.

I did this without a CWM recovery, only stock recovery (holding vol - while powering up).

That's where I started this journey to get it working again lol. The only problem I'm having is with finding my CPUID or the UID he talks about. The numbers I get don't work because they're for the recovery driver, not an actual UID for my tablet. There is no serial number displayed when connected.

Well I had... but I think you just helped me out. Will these show up if I'm using the recovery driver to get it to be recognized? I can find it when plugged in under Acer Iconia, but I think that's from a previous plug-in before I flashed it. Now when I plug it in it comes up under "acer picasso recovery driver". I never new what vendor ID to look for, so I'm going to do that.
Do I have to put serial number in the .txt file named cpuid to get it to work?
Thanks for replying and giving me something to do!

Okay, so I'm in my college class so I don't have my own laptop with me, I'm trying this on a "frozen" desktop. I said earlier my tablet show up in usbdeview as acer picasso recovery driver, but it flip flops between that and acer USB-Boot recovery driver. Don't know why. Either way, when I plug my tablet into my computer and put it in APX mode, it shows up, but no serial number or anything. I'm going to try what you said on my laptop at home where I've plugged it in before I flashed it, maybe I can find it then. Hopefully. Here's a USBdeView picture of what I'm seeing when I plug my tablet in.

Hey so do ours. Gotta love the key combination to get past it
But that's awesome, this gives me hope! Will try this if I ever get out of this class... yay for linux classes that last from 8 to 3.
I have also bricked mine due to not reading things before jumping in as usual doh.
I installed the lightspeed ics beta 5 and it was pretty nice but a game I have been playing kept freezing so I decided to go back to 3.2 official by putting it on the sd card and booting recovery. It went through install etc but then just goes to a bootloop with the blue lightspeed flashing adroid. CWM is no more and like an idiot did not get my cpuid prior.
I tried installing the 3.0.1 unstable too but that did not work either. It just sits on flashing android now.
Will I have to wait until an official acer ics update.zip is available once released?
Thanks in advance

I don't think you'd HAVE to wait for the office ICS update. For you, I'd say do what I've been trying to do which is get it back to stock rom and recovery manager so I can wait for the official ICS update. Eventually, if I ever do unbrick this thing, then I will have to decide if I want to wait or not. Or dual-boot ubuntu

I cant get my cpuid though as it dont show in usbdview either unless I need the drivers from sdk first.
Hey,
first of all: my Acer Iconia A500 is not rootet and I have no custom rom installed. It's all "original" and I don't want to do anything, that kills my warranty.
Yesterday I tried to upload some videos to youtube using "Google Chrome"-browser, but the Tablet crashed when I tried to open the directory where the videos are stored in.
In the top left corner of the screen was written something about a "mounting recovery image" or something like that (I can't remember). After that the tablet restartet but it won't go any further than the "acer"-logo.
I tried a few things I read in the forums but nothing helped:
pressed the "reset"-button at the bottom right side with a needel: tablet restartet but hangs again at "acer"-logo
pressed the "volume down"- and the "power"-button at the same time an released the power-button when the screen turns on: some writings in the top left corner of the screen (something about erasing cache... I could not read it because it disappeared to fast), then an Android-Symbol with some kind of cube in front ob the belly, then an Android-Symbol lying on the back with a red exclamation mark symbol on top of it.
pressed the "volume up"- and the "power"-button at the same time, released the power-button when the screen turns on and switched the lock switch on and off and on and off: top left corner of the screen says "Erasing Userdata... Unrecoverable bootloader error (0x19000008).
Now I really need some help... what can I do to make my tablet work again?
Thanks in advance

Take a look for the ICS UPDATE files for the a500. Might be 3 or 4 of them.
Download them to your PC. DO NOT EXTRACT
You may or may not need to decrypt them first. Should be a Decrypt tool on the same thread.
After decrypt, open the rom.zip with 7zip (or similar zip program) Again, DO NOT EXTRACT. Just pull the update.zip out of it. Copy it to your ext sd card.
Holding Vol+ and PWR, boot the tab and remain holding untill you see the install start.
Now, you may have to try more than 1 of those update roms. But one of them should work.
Should get you going. If not,. your bootloader partition may be hosed and need acer repair.
Oh, and you will more than likely lose most of your data, so don't be surprised if some fotos and such are missing.
MD
I have the same problem as TS.
Trying to solve this but i can't find a decrypter.
You say it in the same thread some where, but it reads "coming soon"
Please help
Acer Decrypter
Here is the Decrypter tool.
Unzip the contents to a folder. Select your rom.zip
Decrypt it. New file will have the word "decrypted" in the file name.
Takes a couple of minutes.
MD
Thanks.
Sadly it doesn't work for me.
Nr 4 the one that doesn't have to be uncrypted seems a bit to work.
My tablet starts up with the acer logo and then i see flashing "ANDROID" for 18 seconds then 2 seconds blank screen then the flashing android again.
This goes on and on, i have let it go for about 2 hours but nothing changes.
Anyone any idea?
help please

This is what I would do if that was happening on my tablet.
First. I would get Blackthund3rs APX tool. Then I'd run it and follow the directions. Basically it goes something like this. Starting at the first screen of the APX Tool. Browse Bundles. Type in number 17 after getting the bundle list from the bundle market. Set it to be staged for flash. Enter your SBK. Use whichever BCT that you want. Enter APX manually, follow the onscreen prompts. and when you get to the end it will tell you to restart your tablet. But first... This next part is really important if you are on a stock rom. Reboot, but do so with the volume rocker pushed for entering CWM. ( The one on the left in landscape.) If you don't the rom will wipe the recovery that you just installed during the boot process and then you'll get to start all over. Once you get into CWM goto the wipe menu and do them all except the battery stats.
From there you can...
Reboot and see if the rom starts. (I'll bet that it will.)
Or you can flash any custom rom that you want/have, (put it on your sd card before you start.)
Or. If you want to go back to stock you could grab a 3.2 stock rom from the link posted above and install that. It will remove the custom bootloader and CWM. You will be totally factory stock after that.
Good luck.
Wow wait a moment.
I am a complete noob with this.
I don't know the you use and as you may have noticed; you're language is not mine language
Stock rom means the original rom ?
Going to search for the APX tool (whatever that means) and take a look.
Thanks sofar.
<edit> SBK is Secure Boot Key. How do I get this key</edit>

U will need either "civato's manual nvFlash" or an "EUU" based rollback (timmyDeans V4) to repair the bootloader - once that's fixed u can flash a stock rom to get back to factory original. Links and guides in the cpuid thread - if u need further help, ask away I know it can be really frustrating and the no.1 cause is always 'drivers', once u can get them installed AND adb running correctly then you're halfway home!! One thing I've learned with the Acer is everything is built upon u following the guides in a strictly orderly fashion, try to skip a step or not complete the preceding step correctly will always result in failure BUT the error will not show up straight away - u might get 3 or 4 steps further along b4 error'ing out...which is why its so darn difficult to troubleshoot....the only thing these tools cannot fix is a hardware issue..if this is the case then it will need to be sent to Acer for repairs....good luck

Acer A500 and believing in xda . . . right or wrong?
My past forum posts say it all with exception of this: (in essence: purchased new stock A500 16GB, forgot pattern, locked up during OTA two days before expiration of warranty Sept 2012 used xda developers suggestions for reset (update.zip) and today have nothing but:
Erasing Userdata... (in white on black screen)
Unrecoverable bootloader error (0x19000008) (red on black screen)
During my time trusting xda developers, I've encountered the full spectrum of online personas - both ends of the rainbow people. Regarding software, I found some interesting things in one of the (opened in "read only") "update.zip" files while just looking through the metadata and other files (I could open in notepad read only) hoping to find some useable reference and indeed found them tampered with. Not sure how you can police everything people post for our "help" but now wonder what my options are.
Not that xda could have forseen Acer rescinding the files, I missed the window of the Acer A500 stock rom last year and any reference now is either very old (2011), 404 - not found, or link to sites which install devious 3rd party software. I take precautionary measures hopefully relieving myself of risk but I'm not a tech. My tablet was not rooted nor altered in any way, just locked. I was able to download all my files with Mobogenie because obviously my keypresses were incorrect and all the information was retained on the tablet until last night. Last week, trying to reinstall a new version of the update.zip that didn't have the words "stupid user" and other code with null directives or whatever it's called in "code" lingo, in the binary file (opened in read only), and also before the wipe found a bootloader installed and how to explain is just too much. Is there a validated, quality reference one can use from xda developers that isn't compromised? Which someone with less than an Associate Degree and older than 15 can follow at this point?
I will donate out of my paltry SS income of 600 a month to whomever can lead me, step by step, to recover my A500 or find at this point it necessary to move on. :fingers-crossed:

How bizarre, never encountered files like that here b4?? There's a root guide in my Sig you're gonna need to look at. All files there have been d/l'ed multiple times with never a complaint, so far!!
First off, an update.zip is of no use.
You need an nvFlash-based tool. Either a EUU like tdv4 or the infamous babsector.rar file.
2nd, you are gonna need yr cpuid. See cpuid guide in my Sig. Until you can retrieve it you're stuck with a brick.
Have a read thru those 2 guides. You'll have questions after that so just post back here

Noob, here. I have a small computer repair business and offered to take a look at a friend's A501. I am quite embarrassed to admit it, but I have searched through these (and other) forums and I am clueless. Due to my complete ignorance, I fear I may have made matters worse by becoming flash happy. Would anyone be able to give me *very* remedial instructions for what to try? I have no idea what the CUID is or how to obtain it, and I know nothing more about the machine than what I am able to extract by looking at it. Humbly, Anne
Let me add that I have searched and tried to follow the instructions on many other posts on this subject, I believe that haven't been successful because it seems that there is a prior knowlege/familiarity required with the OS/device that I don't have. Thanks again.

hehehe 'flash happy' welcome to the club!!! Yes the acer is a strange beast, luckily though its fairly 'unbrickable' unless your tab suffers from the hardware fault prob.
There are a couple of guides in my sig you should look at before attempting a fix.
The cpuid guide for a start, there are quite a few different ways of retrieving this - its all explained in the OP.
The root guide is a500 based, but everything will work for the 501 and has links to all the tools you will need
You don't say whats actually wrong with the tab - does it boot still, is there a custom recovery (power vol down buttons) on there and can you boot to that?
The more info you can give the easier it will be to provide the best solution

Hi Donna-
Yeah, I guess explaining what it's doing might be helpful. Right now, if I just power it up, the acer logo is in the center and in top left corner is "boot verified failed" in red.
Power + vol up, displays in the top left corner:
erasing cache before sd update
sd update cmd: recovery
update package=sd card update.zip
booting recovery kernel image
then it shows the android guy working then the android guy dead
I'll take a stab at determining the CPUID tomorrow.
Thanks again.

EDIT: I'm just uploading a 501 update.zip - the 500 will work ok you just won't have 3G
I'll post a link when its done
ok you might be able to get fixed by heading to the root guide in my sig.
download the 3.1 FULL update.zip - rename it to update.zip and make sure it doesn't end up as update.zip.zip
Copy it to your external sd card
Start the update by Pwr and vol up
If it works your tab will be back on HC 3.1
Grab your CPUID - its the easiest way
From there you can get system updates all the way to ICS OR
Install the v8 bootloader to flash any ICS/JB roms
If it doesn' work you will need that CPUID
Good Luck m8!!

hi all and thanks for your help in advance...
i have been assigned an a500 which is bricked and only shows the acer logo and nothing goes on from there
i have tried multiple roms along with custom roms as an update.zip into an SD card but it stops at the same position which is about 30% everytime on every rom
ive tried fastboot, says the BL is locked and when i tell it to unlock it it just says OKAY and stays locked
now blackthund3r with his apx flashing tool presented some hope as it detected the apx mode but after the flashing starts it wont go into bootloader mode the screen is just black
i have attached a screenshot of my pc trying to identify the tablet with apx not installed for no driver is found
i have installed every driver i can put my hands on starting with the latest from Acer drivers and none of them seems to give me the apx driver.
i think the only problem i have is the apx driver, can anyone point me in the right direction? ive got my SBK from afterota only one time and it never worked after that time. can anyone help with the drivers?
#edit:
i forgot to mention that even though it says apx is not installed, when i connect it in apx mode i have a little usb icon which says "eject APX" call me crazy but that just says apx IS installed right?

i forgot to mention that even though it says apx is not installed, when i connect it in apx mode i have a little usb icon which says "eject APX" call me crazy but that just says apx IS installed right?

Generally, the APX (boot recovery download) driver should be installed with just the normal Acer drivers from the web site. On a Win8 pc, it can be a real pain, so if you have a Win7 pc, I would advise it. I suppose you are looking in Windows "Device Manager"?
Not sure about the "eject APX" message. Sounds strange to me, but maybe it says that on an XP PC, been to long to remember.
Stock Acer bootloader has no "Fastboot" capability. This was added after ICS with a patched bootloader.
Either way, you will need your CPUID number to use any of the NVFlash tools. There are stickies on how to get this, but more than likely you will need a Linux set-up, not sure if there's a windows method.
If the tab had been rooted, and a custom recovery added, there's a possibility there was a backup done, and it would be in the Clockwork Mod folder on externalSD card.

I am running win7 x64 and the apx drivers seem to be installed as blackthund3r recognizes it, its just that in blackthund3r apx tool it never seems to want to get into the bootloader mode i have no idea why.
also regarding my CPUID when i used afterota it showed me :
Tablet Serial : 485FEFA483118011
Tablet Cpuid : EMULATOR-5554
Tablet Sbk : 0xF5030000 0x00000000 0xF0D1E302 0xF0D1E302
Android Build : GT-N7000-user
Bootloader : 0.03.01-HC
now isnt the CPUID a 15-16 digit hex number?
and if my CPUID is wrong in this case above it should mean my SBK is wrong aswell right?
the build number is of a galaxy Note device which is also strange.
also, the device came with no SD card and it has not been rooted or a custom recovery installed on it, the owner says "it just died"
I had the Linux idea in mind as a last resort i suppose its time.
thank you for your help

Oh man, Somebody must have tried installing a Galaxy Note Rom? Got me a little confused on just exactly what you have there mate.
The CPUID as you stated, should be an alpha numeric sequence such as for example (mine)038061c7409fa617.
Why it's telling you it's Emulator-5554 is quite strange. Tell me, how exactly did you get this CPUID? As if the tablet won't boot past the bootloader (Acer screen), then the usual discovery tools we have, can't get it, and this I can promise. I'm guessing it's just spitting out some programming error.
And, I can also say your SBK number is suspect also. Looks weird. Here is mine (no, won't work on yours) 0x79531F00 0xBB680C01 0xFB22E803 0x8ADE2003
I would suggest the following;
There's a user here, dibb_nz, and he has some links on unbricking. Currently he is abroad, so won't answer PM. Also, there is a thread "Why CPUID is Important (might be the same things). In there, are some steps on how to get the number from a dead tablet. No, I've never personally had to do this, but other folks have. I know there's steps from Linux, but believe there may also be windows steps as well.
Another good link from Linux (you can run I dual boot, as I do) http://forum.xda-developers.com/showthread.php?t=1751978 This should be easy to follow, and probably best chance at getting it.
Another good thread from Dibb_nz http://forum.xda-developers.com/showthread.php?t=2049778 Has several unbrick procedures.
I have several factory Roms here on my server. I try getting one whenever I come across them. Acer in all of their infinate wisdom, have shut down their OTA servers for quite some time, and also, they add and delete factory Roms from their official support site all the time.
If I can help you, I will. Some things may be out of my control, but will help as much as possible. We have some pretty good folks here in the 500 forums, but the tablet is getting a bit old, and most have moved on to somehing newer.

I got my CPUID from afterota "no idea how but it just worked for one time, and later yesterday worked again".
when i try "adb devices" it just shows nothing, while yesterday also i tried the same command and it returned with EMULATOR-5554 as a device connected and i could get in the shell but could do nothing from there...
i have seen those posts before they have been helpful but as far as using "a500 manager tool" to recover my CPUID, the tool hasent worked.
anyways i suspect the only way of getting my CPUID is through a linux distribution,and from there i can stumble around with nvflash from there or go back to windows. As I dont have any linux expertise it would be a good experience.

Use Ubuntu for the linux distro. It's by far the most common. Basically you can install it 2 ways.
1) As a dual boot (might have to disable a BIOS setting if your PC is pretty new. Usually only if it was a Win8 new system) Benefit is that the Linux OS will get 100% system resources. Downside is that it'll partition your HDD.
2) Run it under cygwin. Basically an emulator which runs within windows, and you create a virtual drive for the Linux install. The benefit is that you can uninstall it rather easily when finished. Downside is it shares Windows resources.
If you're only after the UID, then probably the cygwin method is better for you.

i've never heard of cygwin, i was thinking virtual machine but i was slacking due to the work it needs doing and my impatience... i must ask if afterota is showing EMULATOR-5554 and i managed to get it in adb mode and it still showed EMULATOR-5554 do you think its even recoverable in ubuntu?

Well, being in the 500 forums, and owning a 501, I can say these tablets are pretty much bulletproof. I've never known one that can't be unbricked. Basically, if it has some life, it can be brought back. Mine blew away the bootloader, hard bricked. Took out the mainboard, slapped it in the oven, reseated some nand chips, and it updated the blob file when I booted it. :good: imagine that!
It's still a little flakey running EUUS files, but it's on 3.2.1 and rooted, so I will leave it on that rather than press the issue any further. Besides, it's only used for You Tube and Browser anyhow.
I would say the Linux method will probably reveal the true CPUID. Afterota seems like it's generating some development code. Like I said, none of those tools will work properly unless the tablet OS is running, so who knows what strange things will happen.
I've never used VM, but it should also boot ubuntu.
This chap just got his CPUID today using a Linux distro.

the oven? im confused what reflowing the solder has to do with anything lol and i hope im not going to that stage haha
im downloading ubuntu now as we speak, im hoping it will work but im confused about the libraries that i need to download, GCC and the other ones, are they something special and special installation required? or sniffing around google would do the trick?

Well, normally after you get an ubuntu install, you can download extra packages. Terminal for one. I'm sure the Ubuntu help center tells you how to get certain packages (lib's and such). Basically you do it via a terminal window. Like I said, I've never used that particular procedure myself, but seems some others got it figured out.
Ha Ha... the oven. Yes, I was skeptical to say the least, but thinking back on rice to dry out a phone, putting a dead HDD in the freezer, well, it seemed plausible. And for me, the oven trick worked. Pressed all the nands back into place, and was able to clear the "Blob update failed" error (was stuck with no working bootloader, hence a hard brick). I attribute it to my 2.5yrs old girl dropping the tab once too often (although was in a good cover).

well i have good news and bad news...
i got Ubuntu and i was succeful in retrieving my CPUID and after that my SBK, blackthund3r a500 tool worked and it got into " entering acer download mode" as in it booted in bootloader mode which is very good, but now when i flash something it is stuck at "stage two-uploading image" and the nvflash command screen is stuck at "resume mode".... well great, now what? lol

Eh, ok, you got the CPUID. Hang on and I'll give you a link for Timmy Deans 3.2.1 rollback.... Sounds like you got a corrupt partition.
OK, download and unzip the contents.
http://www.mediafire.com/download/fo4wqjeald4s3rj/tdv4_rollback_rom.7z
Now, in the contents, you will see the file pbj20upgrage.exe
Run it as "administrator" (right mouse click it and select run as administrator)
Now, don't plug in the tab. After it does a couple things, (installs drivers, starts looking for current build it will eventually prompt you to start your tab in APX mode. Do it. Then connect, enter your CPUID when asked, and it will NVFlash a complete pre-rooted 3.2.1 with CWM Recovery.

Great!
Now, just remember, when you install one of the full ICS Update files (I have a thread stickied in one of these forums), it will change the bootloader, and also do away with the CWM custom recovery. A custom ICS ROM will not run on an HC 3.2.1 bootloader. This is why we had the Blackthunder tool and patched V8 bootloader. Just so you are aware.
Good luck!

blackthunder's tool just WILL NOT RUN on the tab its always stuck on nvflash resume mode, and uploading image, even after i got the tab back to life i have no idea why, and everytime i try to flash the v8 or even v9 BL it just freezes and i get the acer splash screen again, and then i have to rollback again.
is there any detailed tut on installing ics with the correct steps ? it would be much appreciated, HC wont run any recent app and its ticking me

Welcome to the world of corrupted nand memory.
You can try running "babsector" and see if it will NVFLASH repaired partitions.
