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?

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.

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.
[Update Fri 17th Aug]
k for everyone stuck in apx mode try this:
1. Files you will need:
gersmas AfterOTA Tool
The attached zip file which contains an unlocked bootloader v6 file and a recovery image file - unzip to a folder on your desktop.
2. Open Device Manager on your PC
Turn your tab on and connect your min-usb cable to the PC
In Device Manager check USB Controllers for the ACER-USB boot-recovery driver
3. Open the aferOTA tool and click on the "Extras" Tab
In the unbrick section:
"Browse" recovery option and negotiate to the folder on your desktop and
Choose the .img file there
"Browse" bootloader option and choose the .bin file from that same folder
4. Click "Install"
Keep your eye on "status"
Your Tab will vibrate and you should see displayed in white text:
"Acer Iconia a500 apx mode"
After a minute or two you will see displayed in Big White Text:
"PASS"
and in smaller red letters:
"reboot the device!
5. So go ahead and reboot
The first time I rebooted i got "fastboot mode"????
I just powered off and booted up again, .....
IF you do not have a custom ICS rom on yr tab already then reboot into recovery and flash that rom...no probs!!
You'll need to d/l one and put it on yr ext sd first
Hope that helps some of you...good luck

Has anyone been able to revert back to HC using any/all of the following
A) nvFlash hangs at "formatting partition 4....." rollback using timmydeanv4
B) apxFlash - once back on HC does not recognise tab at all, wont extract cpuid neither does a500manager v1.1
C) afterOTA
The downgrade using timmydeansv4 usually does the trick for me but some have reported error "UPDATE FAILED" and then being stuck with the black screen of apx mode.
Would be great to have some feedback on this
if anyone can shed any light it'd be highly appreciated...:thumbup:
EDIT: acer picasso usb driver installs from HC BL nvflash and no amount of uninstalling or reinstalling gets rid of it....acer boot recovery driver is nowhere to be seen and this is the one thats needed

The one that we are working on was never stuck in apx. I don't know how or why, but the tab ended up without an os, or recovery. Also no uid or sbk.
So we used the ubuntu apx recovery method discussed here by srbeen. Once we found the uid, then the sbk. We used blackthund3rs APX Tool to get a working bootloader and recovery.
Flashing roms always complete without any unexpected errors or surprises.
The problem we are having is being stuck in the bootanimation endlessly.
I've been using blackthund3r's and gersma's tools and haven't used the manual nvflash or apxflash methods for quite a while. But that is my next thought on getting this one going. I really can't imagine what's wrong, perhaps the partitions got fubar'd somehow.
So far for me blackthund3rs APX Tool has taken me from apx to any bootloader/CWM combo that I want, but I'm not having any driver issues. I can see where that would ruin the fun.
One thing I might suggest for the driver issue. It might not work, but maybe... If on Windows, go to device manager, expand Universal Serial Bus controllers. Right click Acer USB Boot-recovery driver and choose 'Update Driver Software", choose 'Browse my computer...' and then 'Let me pick...'.
Mine shows two different drivers.

Hopefully one is for ICS and the other is for HC. That's all a big guess. So apply your wisdom before making any changes. But I think that's what I would try if I had those driver issues.

I'll check back thru some of my stuff, it sounz familiar 4 some reason I just can't think why - so yr saying u got the bl and recovery flashed OK but stuck in a boot loop? is that the bl animation or system boot one? I'm thinking a rollback with tdv4 to reset everything and upgrading from there - but if yr anything like me you'll be wanting to actually solve the loop issue....that's where I'm at with folks getting stuck in apx

Yeh this is what I have come to think too
Picasso is for HC and acer one for ICS, no matter what I try the Picasso ones always load and the Acer ones don't show up anywhere....I'm back on HC and about to upgrade again and hopefully all will be well in driver world once again!!!!!
IThe other thing I've been working at is a way to rollback without using an EUU or update.zip
In other words, trying to get nvflash or apxflash to revert back to HCbut the tools automatically install Picasso - when that happens then everything goes haywire, its where some of the tabs hang formatting partitions - which then involvesusing td4 or srbeens method to reset them.....I'm figuring if we solve the original issue folks won't have to rollback/reset partitions.....
I hope this makes some sort of sense J and I really appreciate yr time and input thanks:good:

Makes me wonder if maybe a second pc or virtual pc with only the older drivers and no network running to stop windows from updating the driver? Or perhaps we could look into trying it from that Ubuntu live disc? I think once we were at the point that we found the uids we are close to being able to continue from there...

Ok. I think that this might help. This way should pass with the drivers if I understand correctly. I just did this and it worked on my tablet. First I borked my tablet intentionally by installing an old stock HC rom over my V8 bootloader ICS full root without wiping anything. Then booted it. From there, Bootanimation loop. CWM gone. Useless.
So I entered APX mode manually. I used blackthund3rs APX tool. Visited the Bundle Builder Market and grabbed #17, the latest bootloader and Thors 1.7.3 CWM package. Flashed it, went directly into CWM. Performed full wipe BEFORE doing anything else. Really don't forget to wipe system and delvic. If you do you will learn how I learned to bork my tablet the easy way and get to start over from APX.
Flashed this, https://www.dropbox.com/s/fpdy13u4ufec461/Acer_A500_4.010.38_COM_GEN1.zip it is a very stock 3.1 android version Acer_A500_4.010.38_COM_GEN1.zip. It boots up just fine on the V8 bootloader and once it loads up, hit settings. From there it is easy to just ota to any version that you are wanting. Plus after the first update to 3.2 I'm pretty sure you get the stock bootloader, recovery, the works. Of course you could get root, recovery and restore your backup like I did.
Or am I way off base?

i'm finally back to ics, but it was a real fekin mission - downgrading was the toughest bit specially trying not to use tdv4...nothing recognised my tab at all...then when i did get back I couldnt update the BL...was tearing my hear out....couldnt get the acer boot drivers installed no matter what i tried...in the end i fired up my old vista laptop...and the acer ones installed straight away wtf???? So my theory regarding separate drivers seems to be blown out of the water, altho in saying that...

I've never had any trouble out of it thankfully. It is the goto recovery for me as well. In my experience backups work better using it vs any of the rest that I've tried. Easier full wipes and reliable as heck.

Just to be certain I did it all again this morning. And yep, I'm self destructive as well. But the good news is that the result was the same. I started with the V8 bootloader in all it's Daisy glory. I wiped, flashed that zip, rebooted, checked for updates, did the ota. On reboot it showed V8 bootloader, then the words FLASHING BOOTLOADER popped up, it rebooted again and just like that I had stock bootloader, recovery, rom. {I was going to use an exclaimation point there but new problem... Pc keyboard dying [EXCLAIMATION POINT HERE]. Can't blame that on a bad flash can i??}
I hope that is the easy out that you're looking for. It's easy enough that I've done it three times on my tab in 2 days. But will it work for everyone?
Now to get the APX tool out and put a respectable bootloader and recovery back in place so I can finish the campaign mode for A Great Little War Game... Oh, and find a keyboard...

Hey,
Thanks for keeping that in mind for me! You're so helpful, I don't know how you manage this many projects at once! But there are alot of people that are glad that you do. (Myself included.).
I am just getting back in touch with the owner and hopefully the TimmyDean rollback will do the trick. I'm pretty sure that it will.
In the meantime, did you get time to try, or have someone else try the downgrade with the 3.1 that I shared? It isn't real important, and don't worry about it if you're suffering from M.P.S (Multiple Flash Syndrome) or just plain don't feel like it. I'm only wanting to confirm that my experience isn't an fluke. I need to update a friends tablet soon so I might beat you to it. When I do I'll post the results here.
Anyway, thanks again!
Hi J, no, I haven't tried yr method as yet, but I got some downtime so I'll give it a whirl now, after I get a coffee on the brew, lol.
There's so much good info posted here but it gets lost pretty quick or is buried in a 500 page thread!! The search function only
really works if u know exactly what search terms to use, that's OK if you've been around the iconia for awhile...if u haven't then
the learning curve is fairly steep - even if u are an experienced android user, things just arent the same as yr average android device
and heck if you're a noob its like ppl are speaking in an English language you've never heard before, lol. So I just try to help where
I can, Just my way of giving back something to the community where I've benefitted heaps from, all the devs here, the ones
who actually have all the talent...
I digress tho', I have a brew in hand, so I'll get on with it....and get back to u

Oh don't I know it. I just finished getting a custom ROM installed on a Samsung Infuse. I've messed with HTC's and their s-off, Motorola and Fastboot/RSD, Acer's craziness. And after all of that it was still like jumping in without knowing anything. I didn't even break out adb once or use a tool that accessed it... Java based jar files that are packaged into an installer if you can believe that. And you gotta take out the battery to get started??? Wow... Just wow. It was harder than getting a custom rom on a mid/generic tablet that didn't have a dedicated forum!
And they sure don't speak any familiar form of English over there. Heimdall this and Odin that...
Thanks for trying that out. I hope it goes as well for you as it does for me.
Lol, yes m8, gosh back in the day when the desire came out and getting root with the gold card method what a rigmaroll that was - entering numbers on a website and waiting a day or two to get yr magic code back - it was rather fun ....but only if it worked :banghead: actually things haven't really moved on much have they...anyway I got the rom d/led and flashed v8 and about to Bork, lol so ill get back to it m8....
Sent from my A500 using Tapatalk 2
Yeah, that's too funny. I remember I had a razr in my pocket when I was reading about the gold card thing and thought to myself then that I would never go throught that kind of trouble just to mess with a phone.
I'm not sure what went wrong, but now I am up to my ears in devices that have to be modified. This is clearly not what I had planned back then.
Any luck on the downgrade? It's easier if you don't bork it first lol. Just flash the rom after the wipes.

YES!!! Confirmed m8 works on mine too....hardest part was trying to bork it first, hehehe!! Couldnt get rid of cwm and I wanted to stick as close as possible to yr method....but got the boot loop thing so i flashed your stock rom over it - then apxflashed - rebooted into HC WITH v8 - but of course cwm got over written with the stock image!!! So i tried fastboot - flashed 1.7.3 from there - and booted straight to cwm - did a backup to test out. WHile I was doing that i d/l'ed civs new flex stryker....have to fastboot to flash it but thats ok...in his rom he also has a backup tool so with some luck i may never need cwm again???
uh oh just had a random reboot - oh, all fine..didnt try OTA'ing so i'll leave that lil project for another day...:good:
So well done you, another arrow to our bows, haha - I'm guessing it works cos 3.1 has an unlocked BL - thats just a guess tho...ok off too flash stryker
thanks J for sharing
Sweet.
It looks like it's going to help with both recovering messed up tabs as well as do the back to stock with OTA. Perhaps a guide is in order. I won't have time until Sunday. So unless you get super bored and want to mess with it I'll start on it then. Your guides are always so easy to follow and very complete. I welcome you to take what we've found out and please share it any way that you want. I'll contribute any way that I can.
kewl m8 and thanks!!! I will see how i go m8 guide wise, still workin on the apx mode thing for the life of me i cant make it get stuck, lol always the way aye...ok...and wouldnt mind giving stryker a bit of a work out too.....
oh btw, what happened after u ota'ed to 3.2.1 did u go all the way to ICS or did u end up with the HC Locked BL again?

Yep. I ota'd that puppy until it wouldn't do it anymore. All of the way up to 4.0.3. All stock locked bootloaders after the first flash. So it is definitely a back to stock any flavor solution. All stock except, of course, that 3.1 that we used to flash. And the only thing that isn't stock on it will be the bootloader. Once the OTAs start it is all official acer stuff until the owner mods it.
So really, if someone wants to go from any custom ICS back to stock. They can simply flash the 3.1 that we tested through CWM after wiping system/data/cache. OTA to 3.2.1 and they are totally stock and can go whatever route from there that they want to.
Not sure but I think that might be the guide for that part... I guess that it isn't very complicated when 2 sentences about wrap it up. Maybe a picture of Daisy would add a little spark.
As far as the stuck with only APX mode, that'll take only a little more space.
I think that the only difference will be a few lines that say to get into apx and use blackthund3rs APX Tool to flash #17, reboot directly into recovery, wipe, flash the 3.1 rom.
As far as the issues that you've been helping with, I'll have to defer to your experience on that for any instructions. If I can help with Screenshots or anything else say the word. I've about got it down where I can have images up in almost no time.
Again thanks for confirming that for us. If it helps even a few people the time will have been worth it.
And if you ever need me to bork my tablet again just say the word!

*** SOLVED ***
Hey all.
So I've had my A500 for about a year now and it's been on several different ROMs and kernels over that time.
Most recently, I was running Flexreaper R12 (I believe) and ICS was running very smoothly.
At some point a few months ago (after a Flexreaper update), I was experiencing the Sleep Of Death and flashed an AntiSOD kernel to stop it (which it did). All this time, for some reason or another, I never updated the bootloader past the Honeycomb bootloader - and that's where I'm stuck right now.
I've tried using AfterOTA in every possible way to get anything else loaded.
I've tried Blackthund3r's A500 APX Flash Utility with at least 7 different APX packages, but no matter what I try, I'm still stuck with Flexreaper and the HC bootloader.
FWIW, both AfterOTA and the A500 APX Flash Util experience a problem with my A500 when it reboots. Most of the time I can get the device to be recognized by my OS (Windows 7 x64), but sometimes it doesn't and fails on driver install, even though I've installed the Google drivers direct from the SDK as well as Acer's drivers (USB_Acer_1.00.0524_A30H_A31H_A32H_A500_A501).
I'm pretty sure this is a driver issue, but I'm unclear on how to fix it. I've uninstalled ALL drivers related to the A500, rebooted and reinstalled them, I've uninstalled them and then pointed the installer directly to the unzipped USB driver folder (from above), but it seems that at some point the device fails to be seen, only rarely - but it's this that I think is the main problem... or I'm missing something.
So, any advice for someone that's STUCK on the old 3.01 bootloader?

So how did you downgrade? I've done everything I can think of - at least 6 times over...
That was the plan after I figured that downgrading back to stock and then going up from there was the only way, but I can't even go back to Honeycomb 3.2 or even 3.1.
Check this out - I even made sure to make a CWM backup of my original setup before I upgraded to 3.2 back almost a year ago...but I can't get it to restore. In fact, I made several different backups and can't get ANY of them to restore.
So, in short, what did you do to go backwards?
Psychlone
EDIT: when I try to get into APX or Bootloader, it always ends up in Thor 1.7 and my computer doesn't recognize the device with a device driver install fail for MTP USB Device, even though I've installed the Acer Recovery drivers and the Google SDK drivers too... wtH?

if your on the honeycomb bootloader simply flash a honeycomb rom and kernel no need to use afterOTA or anything else if i remember correctly

you got a couple of choices....
with the HC Bootloader and ics rom...
full wipe and flash an HC rom or
nandroid restore an HC backup or
flash an update.zip
as a last resort - a complete downgrade/rollback use timmydeansv4 EUU - just be sure to follow the instructions in jazzyjames post on how to roll back - iu dont wanna get it wrong and end up stuck in apx mode. If it doesnt work first time....STOP...disconnect yr data cable and reboot tab and pc, use a different USB port and try it again....
Some folks have had issues with win64 so if you are able to then try on a different pc
sometimes a restore wont work unless you restore it with the recovery you used to back up with in the first place which may have been cwm 1.3.4 in your case....maybe???
as far as the MTP driver goes...that can be a pain...i had the same trouble a few days ago on ICS...took ages to get installed....and i still dont know why it did....or why it wouldnt....very frustrating!!!

he's not on the ics bootloader though so couldn't he just flash the 3.01 unstable and get the OTA? or go back to a stock rom in general?

Yeh 2nd line of my post hc bootloader ics rom, and u correct use 3.01 buggy update,zip or stock update.zip I shoulda been clearer - thanks gears
Thanks guys, I really do appreciate the help, but I'm still having serious issues reverting back to HC.
I feel like an idiot, but I have to say that even though it seems so, I'm actually the owner of a computer repair business, have 28 years experience in PC/Mac repair, and have rooted and modded every android device I've owned (including some for friends as well) - all the way back to the very beginning with the D1. This, however, has thrown me for a loop. NOTHING with this A500 has been this complicated! Everything up to this point has literally been stupid-proof and I've actually been quite impressed at just how easy modding is on the A500...
Anyway...
Here's what's going on and what I've tried today:
I've tried unsuccessfully several times to get ANYTHING working on my laptop, but to no avail. Same story as last night, no progress whatsoever - however, I did note that with CWM 134, I was able to restore an earlier version of ICS 4.03 (Flexreaper R10 I believe) - but it wasn't easy... I ended up restoring the main image and then using parts and pieces (using Advanced Restore) from other saves to finally even get it to boot.
This clearly wasn't getting me anywhere, so I moved the entire operation to another computer - my main rig (also a Win7 x64 - in fact, I don't own a computer that's not Win7 x64)
Now I've got USB driver issues! I can't even install the standard USB drivers from Acer's website because the installer errors out saying that there's no version of Acer Iconia 3G Driver Install is installed. wtF? That's what I'm TRYING to do!
I did get a different USB driver installed - the USB Driver_Acer_1.06.1500_A30H_A500, but nothing wants to use it and Blackthund3r's APX Flash Util won't see it, AfterOTA won't use it, and it's basically useless anyway. AND I can't install the Acer_1.00.0524_A30H_A31H_A32H_A500_A501 drivers no matter if I've got any others installed or not.
In my device mangler, there is no device with an exclamation, and in fact, sees my Acer Iconia A500 under USB Serial Bus Controllers as "Acer Picasso USB Boot-Recovery Driver", only when it's plugged in. NO other instance shows up at all.
I'm actually at the point of trying to follow through with the EUU (dibb_nz's "last resort"), but vache's website is down and I can't download anything for it. In fact, there's nothing from that guide that has a valid link...
(http://forum.xda-developers.com/showthread.php?t=1632392)
So now where do I go? I understand IT really well, so you don't need to talk to me like a complete noob, but dang if I can't figure this one out!
If I can get valid links to all the downloads from the link above, I'd be more than happy to give it a go and see if that works, but I can't piece together all those things from random places. If either of you (or anyone else for that matter) has valid links for everything needed to follow the EUU guide, I'd be very grateful!
Any other advice would certainly be appreciated as well! I don't have to use either of these computers, but as mentioned, ALL of my computers have Windows 7 x64 on them. I suppose I could try one of my customer's computers for all this, but that's not morally right and probably something that I would prefer not to explore.
I feel as if I could get the USB drivers installed properly on EITHER machine, that I'd likely be in good shape. I think that's what my problem actually is on the laptop as well, even though they're all installed and shows as installed until I boot into any recovery - then I get the MTP Device Driver Fail. There's likely other Acer driver issues there though, since Blackthund3r's utils don't follow through for anything... everything just hangs. AfterOTA just hangs.
Advice please?
And thanks again for your knowledge!

Yeh I hear u m8, its taken me all nite and day to revert back to HC and then upgrade again....dam pesky Picasso drivers.....
why not do as gears suggested....boot to cwm do all the wipes and formatsand flash an HC rom, ezterrys has a rooted one...no drivers needed . or am I missing something?

Well, I would but no matter what image I put on my SD or even internal SD, and no matter what recovery I use, there's always some type of fail - usually an MD5 fail, or just a fail without any error code at all (little android on his back with the red exclamation, but no code)
I'm clearly missing SOMETHING.
I'm about to try the EUU right now unless there's some other advice...
EDIT::
OK, so I'm really in bad shape here - now the EUU (PBJ20upgrade) comes back with the error:
Please download the newer image for the upgrade.
Current image version: Acer_AV041_A500_1,054.Acer_AV041_A500
New image version: Acer_A500_1.016.05_Com_GEN1
What now????

oh hell now i'm confused, lol.....the little android dude is the acer stock recovery....i thought you had thors 1.7...oh well, nvm
Hopefully the EUU will install the right drivers for you....just be sure NOT to connect your data cable until u see the "cannot detect yr iconia tab" screen and it will give u instructions on how to get into apx mode...oh just before that window the EUU will try and scan your system image it will take a good 5 mins b4 it pops up the window to go into apx don't panic just let it do its thing....good luck m8!!!!
Oh and this will completely wipe yr system and user data.....

Some of the WEIRDEST stuff I've ever experienced - EVER.
Oh, the little dead android is when I'm using the stock recovery - I get different errors in TWRP and all the CWM Thor's that I've tried...(134, 71 and 712)
OK, so now PBJ20upgrade won't let me advance because apparently my CPUID isn't correct... it's the ICS version that's 13 characters long instead of 15, and my dmesg doesn't even contain the word "androidboot" at all (it does, however, contain a crapload of errors.)
What's going on?
OK, I'm an idiot. I really need help. I'm just glad that I'm 40 and don't lose my cool anymore, otherwise, I'd be freaking out about now.

Thanks so much dibb_nz... I've currently got PBJ20upgrade doing *something* (says it's going to take 10 minutes)
Thing is, I didn't get to this point by any conventional means - I followed the destructions several times over but ended up having a newer image than PBJ wanted, or the wrong CPUID.
I finally got this far by unplugging the tablet while PBJ was running, waiting for it's long error and instructions on how to get into APX (which I've clearly done at least a couple dozen times by now) and for some reason when I plugged it in, it shot forward.
We'll see how this goes - I'll keep you posted. I do VERY MUCH appreciate the help. I just might still need it, but hopefully not.
EDIT: Just rebooted and saw a "PASS" on the screen, followed by the "android" loading screen.
EDIT 2: It rebooted all the way in, I signed in (did the entire sign in process) and I'm BACK TO STOCK!!!!
Ok, so thank you THANK YOU THANK YOU for all the help - just being a sounding board is all I need sometimes.
Last questions to get me set up for the future:
What recovery should I create a restore with?
Then after creating a restore, should I use Blackthund3r's utility to flash an unlocked ICS bootloader, and if so, which package should I use to be able to test JB but still be able to go backwards to an ICS (preferably CM9)?
Anything else that I might need to know? (keep in mind that I've read on the order of 30 different threads pertaining to this adventure since it began a couple days ago, but I really appreciate the advice you've given and clearly you know what's up with the A500 - AND, it's hard to disseminate info from all the random threads everywhere. Speaking of which, why is it that there can't be a single thread with most everything that an A500 owner would need? Seriously!!)
Thanks again,
Psychlone
With what I went thru use Civs nvflash and rom and I'd stick with third cement until your safely patched and on ics.do all the wipes and follow instructions to the letter ...I'll check back in shortly
EDIT wtf "third cement" dang auto correct ... should read thors recovery
Wow - what a journey.
I'm now running CM10 and loving it.
I really can't believe the process that I went through over the last couple days - I've rooted and modded two dozen devices in the last year alone, and have been playing with root and modded ROMs since the very beginning, and nothing comes close to what I just did.
I actually have to blame not having everything I need in one place. Mis en place means to have everything you need before you even start - and that used to work back in the day, and still does to an extent for some devices, but anymore, the download links and information are found scattered across many different websites and forums and threads - so much so that it's apparent that this is a product of Google's lack of grip on their hardware and OS.
I do, however, see that you and a couple others have done a KILLER job of getting most everything together in one place to make it easier for those that are searching. I really appreciated your threads that I've read - the way you've written your guides is very intuitive and easy to follow, even if they didn't initially work for me.
Anyway, thanks again. I'm not going backwards now, but if I ever need to for some reason, at least I'm a bit familiar with the "worst-case scenario"!!
Take care man,

(keep in mind that I've read on the order of 30 different threads pertaining to this adventure since it began a couple days ago, but I really appreciate the advice you've given and clearly you know what's up with the A500 - AND, it's hard to disseminate info from all the random threads everywhere. Speaking of which, why is it that there can't be a single thread with most everything that an A500 owner would need? Seriously!!)

Wow - what a journey.
I'm now running CM10 and loving it.
I really can't believe the process that I went through over the last couple days - I've rooted and modded two dozen devices in the last year alone, and have been playing with root and modded ROMs since the very beginning, and nothing comes close to what I just did.
I actually have to blame not having everything I need in one place. Mis en place means to have everything you need before you even start - and that used to work back in the day, and still does to an extent for some devices, but anymore, the download links and information are found scattered across many different websites and forums and threads - so much so that it's apparent that this is a product of Google's lack of grip on their hardware and OS.
I do, however, see that you and a couple others have done a KILLER job of getting most everything together in one place to make it easier for those that are searching. I really appreciated your threads that I've read - the way you've written your guides is very intuitive and easy to follow, even if they didn't initially work for me.
Anyway, thanks again. I'm not going backwards now, but if I ever need to for some reason, at least I'm a bit familiar with the "worst-case scenario"!!
Take care man,
Psychlone

hell, i havent got round to cm10 yet!! i'm trying to get there but i have too much fun helpin peeps get to grips with flashing BL's...have to really thank the devs they did an awesome job unlocking ICS so everyone can enjoy the custom ICS/JB/CM roms- they've extended the life of our little iconia an extra half year or so if not longer.....imagine if we had to put up with stock 'anything' lol, i'd have traded it in long ago!!

CM10 is SLICK. Think CM9 on graphics steroids and you're close!
I appreciate your position more than most. I get a lot of enjoyment out of helping others as well - I've written overclocking guides for AMD systems that was written years ago, revised a couple/three years ago and is still used to this day, even though I've long since moved over to Intel's "dark side". I also participate pretty deeply in helping others at a couple PC hardware forums pretty much daily, even though that's my actual job - I own 2 computer repair businesses in my hometown, and with well over 20,000 computers to fix, I'm ALWAYS busy but still always find time to help others in need.
As for adding ***SOLVED*** to the title, I'd love to...but it won't let me. Perhaps it's because I don't have a high enough post count, or because it's reserved for Mods, but I can't do it.
Thanks for everything once again - it's quite refreshing to be on the receiving end!

My colleague brought his stock A500 to me in a bricked condition last week.
I need a way to restore it. If I try to do a wipe it will say bootloader error if i try the recovery the droid falls down with the red sign with the exclamation mark.
This tablet has never been rooted, my colleague is not in to such things, it's lived its life with ordinary acer otas and the occational very young human (5 year old) trial wich it has survived.
He has installed all the OTAs he ever got on the tablet and this is in Sweden so it would probably be a 4.0.3 acer stock on it now.
I'm guessing it has died during a OTA or something. if i turn it on it will sit at the acer logo indefinitly.
I Bricked my A500 during a rooting atempt resulting in me needed to flash a stock rom to get it working again, but i cant find the thread i read to un-brick my A500.
Please Help!

Well that thread seems to hold all i need, although i can't do a full wipe. when i do the flipswitch wipe procedure it halts with bootloader error
Im hoping to just be able to flash the stock rom from the link you gave me. Is it entirely necessary to do the wipe prior to flash? can i wipe it afterwards?

we're assuming the tab is full stock and currently on ICS...
and we're assuming he never tried to 'fix' his tab by flashing one thing or another...
the bootloader error worries me...what exactly does it say...
Yes the wipes are really important!! and not being able to use the button method to do so is concerning...
what happens with the Over The Air (OTA) updates is its just that...an update...it leaves all your settings/data intact. When you OTA from one build to another, like Gingerbread 3.0 to Honeycomb 3.1/2 and then to ICS 4.0 - you drag all your apps and settings with you and of course some things that work with 3.2 will not work under ICS....fjor instance, lots of folk had trouble with wifi disconnects, once they got to ICS - or they had apps force closing and other 'glitches'. This is why everyone tells you to do the wipes - as this fixes these things! In the case of stock ICS my gmail would f/c all the time no matter how many times I wiped/formatted....So for a smooth running tab - flash a custom rom!!!!!!
But getting back to you...
From that link i gave you...download the 3.1_Full.zip....its decrypted so just extract it and get the "update.zip" from it..
This "update.zip" is not an incremental "update" but the full stock rom....
once installed you'll be on GB you will need to root it with iconia root and then use acer recovery installer to flash cwm....(get these from the playstore)
do a backup or adb devices so you can get your CPUID....this is important...if anything goes wrong at any stage this is the only thing that will get you unbricked....see the cpuid link in my sig for more on this, please take the time to read it, even if it doesnt make much sense to you, read it anyway....
AFTER you have retrieved your cpuid, you can nvflash the patched bootloader/recovery pkg which means you are able to flash ICS/JB custom roms
they cannot be flashed via cwm like normal...you must use nvFlash to do it....
OR
take the OTA route to ICS...this takes a bit of time...I did it last week and it was a good 6-7 hours to go from GB to ICS
there are pre-rooted stock roms if you wanna stay stock see civato's stock rom thread for that here http://forum.xda-developers.com/showthread.php?t=1633907

I am in a similar situation. Push the power button and it goes to a screen with white acer on black and stays there. Totally stock ICS, no root. I tried the update.zip thing and after automatically rebooting it says "Boot verified failed...". I don't have my cpuid, or have installed previously CWM or anything like that. I can get into APX mode. This guy here: http://forum.xda-developers.com/showthread.php?t=1751978 could only get into APX with no cpuid as well, but i don't understand all of the ubuntuu and command line stuff. I would love for someone to be able to walk a dummy like me through this mess. Thanks for any help.
if u got boot verified fail error you need nvFlash to repair that....as u know, with nvflash you need yr cpuid....wot about usbdeview? if you've never plugged yr tab into yr PC - then it won't work and the ONLY other way is Linux....
might be best to start yr own thread with a descriptive title, not just a help I'm bricked no uid, thread there are hundreds of those....the more effort u put into the title the more likely you will attract the attention of someone who can actually help...and remember you just don't need a bit of help but a blow by blow description of what to do and how....this will be very time consuming....at the very least get ubuntu installed, maybe just try a few things, anything to show you are capable of at least giving it a go yourself..
there are others who would like 2 know how to do this as well...having a specific thread of its own would be great
good luck

Actually, I have connected it to my PC before. Only for transferring media though. If I've done that, is the some way to retrieve my cpuid from the PC?
yup...usbdeview.zip see the bottom of the OP in the cpuid guide in my sig
Thanks alot for your help. I used usbdeview and got my cpuid. Now I should use nvflash? Know where a good step by step is for that one?
you could try the one in my sig??

Right. Sorry, I didn't notice that before. Thanks again for your direction.
"To install one of these roms you will need a custom recovery and to get that you must flash the patched bootloader FIRSt - once its patched you can install a recovery any old way you like"
Looking at that guide, would you please tell me what a custom recovery is and how to get one? Btw, I don't plan to do a custom ROM yet, I just want to get the damn thing working first. Was thinking of using the HC EUUs from the firmware files list. However there are two files, a .rar and a .exe listed. Which do i use?

The .rar EUU is for an A500, the .exe is for the A501, which do you have?
I've got the a500. However, I decided to go with a custom ICS rom after all. I managed to put a new bootloader and custom recovery on using the a500apx flash tool. That part went fine. I flashed this rom:
Acer_AV041_A500_1.054.00_WW_GEN1-FULL-ROOT (original odex)
and that appeared to go well according to twrp, but after rebooting, it just shows the bootloader again and stops there. Not sure what i did wrong.
I renamed the rom update.zip. Should i not have done that?
well congrats for getting thru the flash process with no probs!!!
as far as renaming to update.zip that was not such a good move...hopefully things havent been screwed up too much
just go back into recovery and do a FULL wipe/format
then to flash use the option "install from zip file" not sure where that is in TWRP but it will have one
Okay. I will reflash the rom after completely wiping again. Thanks.
On a different note, why do roms require particular bootloaders?
Also different, how do you like your SGS3? If i can manage to fix this thing, perhaps I'll root my phone...

The stock ICS BL is encrypted - more or less - the only way to 'flash' a recovery or rom is to have the "key" that "unlocks" - it more or less - if you dont use the right key then the OS will not boot - the 'key' is based on your cpuid which is why everyone is forever telling you to save it somewhere safe....

I enjoy the big screen, took awhile to get used to it in my hand, kept dropping it....then I ran it over with my 44tonne truck after 3 days and munted it!!!!
I have a case for it now, and its gr8 - I havent installed a rom on it yet...the forums over there are jampacked and I have no idea what I'm doing, lol - its the first android device I've had that I've left stock for so long...but it does what I want...the camera is awesome -burst mode is the bomb - BUT do I think it was worth the money???? Still on the fence about that one.....
Ouch. Sorry to read about running over your phone. That would kill me. I really like my SGS3. I think I'll look into rooting it just to be able to back it up and get rid of the bloatware. I did that on my Captivate and prior to today, thats all I've ever done modding wise to an android device.
So, I managed to get my tab up and running again. Yay! I reflashed the rom w/out changing the name and worked like a charm. Now If only I knew why this happened in the first place... Thanks for all your help.

yeh sometimes happens with the tab for some reason - thank your lucky stars it didn't get stuck in apx mode...if that happens its normally a hardware fault so theres not alot u can do...I'm just pleased you got sorted without too much drama and it was as easy as reflashing the zip....so now you have the v8 BL - you're gold!!!

I googled your error - the consensus from what I read is a corrupt OS due to running OTA updates...
Some had luck with rebooting. Others had to send it to Acer.
Did you run the update.zip? so what happens when you run the update.zip
Are you able to get into "apx mode"? If you can, hook up to your PC and see if your tab is recognised as an "apx device" - check "Hardware, Printers in win7"
Thats all I can suggest atm - if your tab does get into apx mode OK then you can find your cpuid by running Linux -
Maybe ask the guy if he's ever had the tab hooked up to his PC like to transfer files and stuff - get him to download "USBdeview" to his PC -
this will show every single device thats ever been connected to the PC and it will show the "cpuid"...
Even if we do get the uid theres no guarantee it will fix the bootloader error - but we may as well explore all the options we can....
dibb_nz said:
USBDeview will only work when you have previously plugged your tab into the PC WHILE you were running HC Rom and BL
1. If you haven't plugged your tab into this pc before, do so now, before you run the program. HC ROM/BL ONLY
1a. Run the exe and you will be presented with a window of all the USB devices you have ever plugged into your computer.
2. Click on "VendorID" column along the top to sort them
3. Look for the number "0502" under Vendor ID AND "3325" Product ID
4. In the serial number column will be a 15-digit number this is your device ID.
5. Write the number down and put a 0 in front of it and now you have your CPU ID!!!

Wow, you might have screwed the pooh on this one.
Did you install the V8 or 9 Unlocked bootloader?
Ok, for starters, WHICH EUU and what is current operating system?
Did you flash a custom Recovery (in this case CWM)? If so, what version?
But BEFORE you do anything else, you should get your UID number from Civato's sticky thread or one of the others. Very important. So check the sticky threads, there's a simple app to get your UID. Save it somewhere in like Notepad.
Then report back.
ok let me say ive been rooting my ohones since the OG droid, its been 5 or 6 diff since then but this tablet has me stumped... can you please tell me how i can find which version bootloader? the euu file i got off of tegra forum owners, ive got cwm based recovery v5.5.0.x 9thor2002ro rev 1.7) and as far as operating system ive flashed 3 diff roms so far the 1 im on now is flex resurection rev1...4.0.4 android version, ive tried 4.0.3, and jb... i have cpuid if thats the same as uid#...? if you could help in any way its much appreciated...

Ha ha, no mate. No doubt you are a bit familiar. Phones is different than tabs though.
Ok,, when you start your tab normally, you should see the bootloader version. Upper left corner.
There's only a couple EUU files, and I believe both are Honeycomb.
CWM ver is ok.
But if you are running ICS or JB roms, on a HC bootloader, than that's not OK.
So, I need current ROM and version, and current bootloader version. Civato has several roms.
Just wanna see where exactly you are at right now.

3.11 sounds like an HC bootloader, or one of Skrilax_cz's initial bootloader. If you try running ICS or JB based roms, you're gonna get a lot of screwy stuff going on, Like display glitches and stuff.
You need to goto Civato's Bootloader thread in the Dev forum, and try running the apps listed there to get you to Skirlax_cz's unlocked bootloader for ICS. Works for CM JB.
@dibb_nz also has a thread there, explaining things about UID and stuff.
Then, after you get the unlocked bootloader NV flashed, throw CWM on there. I use 1.7.3 I believe. In mounts and storage, there is an option to format your internal SD. Select the option, then do your wipes and formats. Then flash the rom.
Think you'll be okay then.
recovery also says thor kernal v1.16mini running itsmagic that is on the screen when i run a backup....

It's magic is no longer needed for unlocked bootloader and ICS/JB.
If you boot holding PWR and Vol -, you should boot into the V8 bootloader menu. If you don't, there's an issue.

Well, sounds like the emmc memory is hosed. As you read in the threads, it happens sometimes.
However, as a last chance, there is a thing called "bab sector". I've never used it before. Supposedly helps recover bad memory blocks. I've tried searching for it here in the forums, but must not be using the right search parameters . Found discussions on it in @Skrilax_CZ bootloader thread. It's labeled for the a501 but doesn't matter as partitions are the same I believe. He knows more about the memory partitions, so may want to post the issue in his bootloader thread.
But, I do happen to have one of the zips on my Dev Host server.
http://d-h.st/iQX
If I remember correctly, there are 2 variants of this repair file. @dibb_nz might know more about it.
Also on my server. is an HC roll back tool. If not mistaken, it may have a different variant of EUU. Might wanna run it and see if it resets partitions. As it seems like things screwed up when you ran an EUU.
http://d-h.st/0x7
At any case, I would run the EUU again. Can't hurt, and maybe will reset partitions.
thank you that bab sector file how would i go about installing that? flash with the a500 apx flash tool ? and the euu i believe get done that way also?

Ok, never run the Bab tool before. But looking at it, you have to be in APX mode just as you would to run NVFlash, as it operates the same way.
With the Bab tool, if it errors out writing any of the partitions, it should at least generate an error message. Now, you'll have to search to find out how to manually get into APX mode. But if I'm not mistaken, it's tab off. Hold PWR and Reset button. Then count to 3 or 5, release reset, then 2 counts later release PWR. But please do not quote me on this. Been some time, and primarily I work on the A701 now. But it's pretty close.
Then, run the bat file in the zip via a command window. Note I have never had to use this before.
The rollback/EUU works just like any other EUU. Has an exe file in it to run (make sure USB debugging is on, and remember to get your UID.
I also have an ATT EUU handy. Not sure which version it installs, but will be HC.
I still say to post a note in the Bootloader thread. Skrilax_cz knows more about the 50x partitions than even Acer.

Ok, never run the Bab tool before. But looking at it, you have to be in APX mode just as you would to run NVFlash, as it operates the same way.
With the Bab tool, if it errors out writing any of the partitions, it should at least generate an error message. Now, you'll have to search to find out how to manually get into APX mode. But if I'm not mistaken, it's tab off. Hold PWR and Reset button. Then count to 3 or 5, release reset, then 2 counts later release PWR. But please do not quote me on this. Been some time, and primarily I work on the A701 now. But it's pretty close.
Then, run the bat file in the zip via a command window. Note I have never had to use this before.
The rollback/EUU works just like any other EUU. Has an exe file in it to run (make sure USB debugging is on, and remember to get your UID.
