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.

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.

Yeah, it should be listed on your laptop if it was plugged in while running honeycomb.

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.
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?

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.
http://forum.xda-developers.com/showthread.php?t=2049778 and go to the second post.
Not saying it will fix it, but it might.
Have you tried running an ICS Update file?

i have basically tried every ROM available and got nothing in return, running babsector gave me an error about formatting partition failed, although when i booted i had a green screen with v8 bootloader on it but it wont boot not will it install any rom and it says, kernel failed or something i dont remember. I have decided to abandon the project and just give it back to the owner with HC 3.2.1 and get it over with
