[Q] another brick story

I have been working on this for the past few days and for the life of me cannot figure out the problem. I'll start by just laying out a sequence of events.
Bought A500 about a month ago. OTA'd to HC 3.1 4.010.13_com_gen2
Decided not to wait for OTA 3.2 and rooted with iconiabreak.
Did not do a backup (like an idiot, i know)
Flashed Taboonay 2.0 with Thor's 2.1 kernal.
Saw awesome post to get rid of cell standby by deleting phone.apk and telephony.apk....do i did that.
Realize i am an idiot and then run a Nandroid backup.
Was happy for a few weeks when i see that Vache had updated taboonay to 2.1b and decided i wanted to do that.
Downloaded the files and started to flash with CWM. Factory, cache, dalvik wipe. Run Taboonay zip.
Get stuck in bootloop at Taboonay boot screen. $#!t......
Think "it's ok, ill just do an update.zip and go back to 3.1"
Try almost all the files on Vache's full package and update thread.
I put each one on an ext sd card and throw it into recovery boot. The Android guy with gears shows up and it looks like it is going to work.
The progress bar gets about 90-95% of the way when everything just stops. Gears animation, progress, everything.
It then reboots and gets stuck in a bootloop at the android screen. Load a different update.zip and same thing happens each time.
I try to just do a normal recovery boot, but CWM isnt there anymore and i get the ! android.
Normal reboot gives me a bootloop.
So i am stuck and asking if it is the phone and telephony apks that caused everything? if that were the case, how would i be able to load them back up since im totally locked out. I havent tried adb since im out of town for a few days. Thanks for any help that anyone can lend me. Ill try to answer any questions for any information that might be needed.

bumping for great justice~
I've tried decrypting update.zip files and vice versa.
still no luck..

try the fall back to 3.0.1
Check under development section for iconia a500. You'll see a thread for going from 3.2 to 3.0.1.
As i readd about this rom, it seems it's used in difficult cases (it removes the locks created by 3.2 stock), so it could be worth giving it a try.

Thanks for the reply.
I don't think that will be a viable option for me since i'm not able to get my UID. i've plugged my tablet into the computer and gotten the "hardware found" bubble. It prompts me to look for drivers (which i havent be able to find) and, i assume because it's in a bootloop, wont show up on the computer.
Does anyone know why the update.zip files would fail at 90%? I think that's really the thing that boggles my mind and is most frustrating.

Did you at all have your A500 connected to your computer prior to this happening? If so then you can get the UID from by way of the Windows registry. Then you should contact SC2K and get him your UID he should be able to help you get your A500 back from the dead.

Unfortunately, no I never plugged my A500 into my computer.

quick update:
I was able to use a different computer and found something interesting.
While trying to transfer or open a decrypted update.zip file, i get an error message saying, "Please insert the last disk of the Multi-Volume set and click OK to continue". Clicking OK just brings it back and i am forced to click cancel.
Anyone have any idea what that would mean??? It doesnt happen when I open or transfer the non-decrypted file. Only the decrypted file using Thor's Acer Update Decrypter application on HC 3.1 and 3.2 files.
While loading the decrypted update.zip on the A500, it almost instantly shows the ! android guy, while the non-decrypted files go 90-95% and then reboot into bootloop.
Any help would be greatly appreciated!

first off if you can get into recovery to flash anything.You are not bricked.
Take your SD card put in a android phone format it.
Put the card in your computer.copy a full update.zip file from dev section.likes on a post by Thor.put card.back in tab and flash.
If it stall fails repeat with a different SD card.seems smaller ones do best.
Good luck.

Thanks for your reply, first off.
I'm sorry I didn't make it clear that I had done all of those things during the events of the first post EXCEPT try a different sd card.
So I went out today and bought a PNY 2GB sd card as opposed to the SanDisk 4GB i was using. I formatted it in my Atrix 4G and threw a full update.zip file in there. The first file I tried (from Vache's http://forum.xda-developers.com/showthread.php?t=1113878 thread) was Acer_A500_4.010.38_COM_GEN1 (HC 3.1). Since I was able to open the .zip without decrypting it I loaded it only the sd card. It did the same thing as before (loaded to about 90% then freeze, reboot) except this time I got a "Boot verification failed..." message in bright red letters up at the top left of the Acer screen. Since it didn't work, I loaded Acer_A500_7.006.03_COM_GEN2 (HC 3.2) onto the sd card. Again, since I was able to open the .zip file, I assumed that there was no need to decrypt it. Loaded the sd card and put the tablet into default recovery (not CWM recovery which I no longer have). The same problem keeps happening: it loads to 90%, freezes then reboots. This time, however, it went into a bootloop at the "android" screen.
I've tried decrypted versions of those files, but I always get an error message while trying to open them and when trying to flash them in default recovery, it almost instantly goes to the ! android guy since I'm assuming those files are already decrypted and decrypting them again is bad.
Hopefully if I try enough files, I'll find the one that works...
Until then, if anyone has any ideas as to what I might be doing wrong or should be doing differently, please let me know!
Thanks.

there is a thread that has instructions on going from the OTA 3.2 to downgrade. To 3.1.look for that tthread and windows software. On that thread it talks about that error your getting.
Since I have not had this issue .can't say for sure if it will help.
Good luck sorry I can not do more to hhelp
Just a dingy blonde here.

Thanks for your suggestion.
I was able to find my UID from an old CWM backup file and tried this method. I attempted it last night with no success. I was actually in the middle of making a reply saying how heartbroken I was and that I was basically giving up. I decided to try it one more time and made a slight adjustment from my method last night. In the UID file, I had my UID in there as 0x0blahblahblah and kept getting the incorrect UID error in the program. When I tried taking out the first 0x in the program, it gave me an incorrect format error. That is where I was messing up.
Instead of 0x0, all i needed was 0blahblahblah in the UID file.
Attempted the upgrade utility again, and viola! It worked like a champ.
So thanks again to all that helped out and offered suggestions and to all the Devs for their outstanding work. I've definitely learned a lot from this experience.

Bricked A500 in Houston area will pay you to fix

I live in the Houston area. Bricked my A500 will pay you to fix email me . I went from CWM v5 1.3.4 to 1.7 and now I can only go into boot loader but nothing can be applied , tried different ROMS wipe everything still nothing
[email protected]

If I lived in Houston I would try to help you, can't you get into recovery? What happens when you connect to your PC ?

No kidding, I don't live there either, but to help, we need some more information.
You are probably on the HC bootloader, which is why your roms won't install.
Check the bootloader Install sticky in the dev forum. You need to upgrade it to the V8 bootloader.
Then you can install the ICS and CM10 roms.

I have a similar problem. Bootloader V8 installed fine. But when I flashed different ROMs through CWM (install zip from SD card inside recovery), it hung at the screen "CZ's Bootloader V8, booting primary kernel" forever. Scratched my head for a couple of nights now, wondering what the glitch was. I even tried Bad Sector's V8 green. Same result. Help!!!!
Edit: I can still downgrade by flashing EUU (though not TD's V4, which installs fine but won't boot back up once I turn it off and on again???). Anyway, running HC 3.0.1 does make you feel like a Neanderthal. A clear instance of cruel and unusual punishment, I'd say. Even HC 3.2 won't stick! WTH?

Hello. Anyone? How about Mockba the Great? I'll do more than thank. I'll grovel at your feet (lol); or fly to your city vodka bottle in hand. Be compassionate and tell me something. Anything. Like my tablet is shot beyond salvage, so I can put it to rest. Why is it that I can flash EUU and use without problems but not any other upgrades? Is it possibly because of physical bad sectors lying in the path of data from the new roms (sizably larger than HC)? Or automatic remapping of NAND shot to hell? There's got to be some explanation.

I am not sure, but, I have the same problem. If I flash the EUU (Acer stock 3.01) , I can spend a couple of hours following the upgrade path all the way to ICS 4.03, then it seems no matter the boot loader/recovery combo I flash, I either end up stuck in APX, or I get the new boot loader/recovery, and the original Rom boots fine, but when I try to flash using fast boot I end up with the android on his back with the red exclamation.
It may or not be related, but the very first time I tried flashing a new ROM, I ended up stuck in APX, & the only way I could find to get out was to use Badsector. The next Rom I flashed left me again in APX, so, the first thing I went back to was BadSector, & it would not work. (Can't remember what the error was, but it wouldn't get far before stopping.) So, I tried APXFlash & it worked perfect. (Before I ran BadSector the first time I could not get APXFlash to work at all.)
Now I can flash as often as I want, but still can't get anything to work right. (Except Stock stuff????)

This is my guess: I was able to get someone with the right equipment to probe into the NAND and scan. The result shows random bad sectors all over the place. The scan lasted for more than a day without finishing, so eventually remapping could not be executed. If the capability of the NAND to remap is exhausted then depending on your luck, if the ROM data fits into good sectors, you get to use the unit. If the cache partition has black holes in it, you'll get errors and operational aberrations. If I'm right, then this is purely a hardware issue which will come back to haunt sooner or later. Makes sense?
Since the NAND is soldered onto the Main Board, there is little chance of replacing the NAND, if you can find one, that is. Darn it!

I had similar issue in the weekend, flashed Thor's JB romv17.....stuck on same screen as you, had a heck of a job getting things working again.....
So tdv4 installed without errors but wouldn't boot, is that correct? What screen did it get stuck at? With the earlier versions of timmydeans EUU u must boot straight to cwm and "fix permissions" in the "advanced" menu options (I think its in that option)
Other than that I can't offer u any further suggestions I'm afraid....

This gives hope. With TD V4, it stops at power on - power lights on (white LED), but screen remains dark. Thanks for sharing your experience, I will definitely try when I get back to it at the end of the month. So if I'm slow in posting the outcomes, you know why. One more favor to ask: what do you do after fixing permissions while on earlier EUU (I remember seeing that option somewhere in the recovery menu)? Should I proceed to flash V4, then move up from there? If I install V8 Bootloader while on V4's ROM, would that hinder further flashings in any way? Many thanks again. And what is going on now with your JB ROM? And Happy Thanksgiving to all the Yanks in here!

Ok, so here's a little info for you folks. Not sure if it helps you or not, but might clear up some of the mess that's been going on concerning bootloader versions VS Roms.
So you run one of the RUUs files. That's fine. Essentially you should be back on an HC bootloader running an HC rom. At this point, all your partitions should be back in place, especially if you used TD's tool.
While you are in HC, and everything is running fine, you should make a note of your current UID number. Because, after upgrading to ICS, your UID number will probably change. (the converted SBK number should be the same with both). But the RUUs seem to mostly want an HC UID number.
The issue, is when upgrading to ICS. If you do this the normal way via OTA, you should eventually get to ICS with a stock ICS bootloader. At this point, I would leave it alone for a few days, just to make sure it runs normally. Again, get your new UID number.
Now, here may be what you folks are missing.
With the introduction of ICS, Acer pulled a fast one on us. They introduced a little file called recovery-boot.p, and also a recovery.sh file.Both reside in /system (not sure exactly which folder for one of them, might be /system/etc or /system/bin.)
The issue, is that if you NVFlash V8 bootloader, and let's say Thor CWM 1.7.2 or 1.7.3, without deleting those aforementioned files, when you boot your tab, guess what? Hasta La Vista CWM, and mr android is on his back deader than a doornail. Not to mention you might screw up a partition or 2 along the way. And then it's back doing the whole thing again, sorta like groundhog day.
If you get Skrilax_CZ's bootloader running, then there's no real reason why you can't load a compatible CWM to flash roms.
Personally, I don't like the little 1-app-does-all. I prefer the old fashioned way. NVFlash from a command line. This way, you can see if there's errors coming up. Also, you may have better luck trying one of the older packages for the V3 or V4 bootloader. If you guys are interested, I can research my other drives in a day or so, and come up with one of the original packages. Am sure I saved it somewhere.
But if you get the V8 loaded, then you can boot it into fastboot mode. From here, you can fastboot a good CWM image. And at this point, I strongly advise CWM 1.7.2 or 1.7.3. After you fastboot it, boot immediately into CWM recovery. Do not pass go, do not collect $200, and do your wipes and formats and immediately install a custom rom. If you boot back into your stock rom, sianara..... This is why it's best to already have your custom rom.zip on your SD card.
Now, roms, kernels and bootloaders. The rom you choose to install, is pretty important. It needs to be recent, and designed for the ICS bootloader (V8). Using some of the earlier roms with kernels is asking for trouble. HC based roms WILL NOT run on an ICS bootloader. Remember that also, and vica-versa.
It's possible, however unlikely, that one of you may have unrecoverable corrupt data on your chipset. It has happened, but it's rare. Generally, you will find this when you can't get anything running. Period. Or in the case I know, the user could not migrate from HC to ICS. But only 1 or 2 people I know have had this. Oh, 3. I forgot Civato who totally cooked his internal memory (more than likely while inventing his own version of TWRP)
Wipes and formats. Again, I can't stress this enough. There have been issues using TWRP when it comes to wipes and formats. It seems, sometimes, things don't get fully wiped. So, as I always do with CWM, remember those versions I quoted), always
Wipe Data/factory reset
Wipe Cache
Wipe Dalvak
Wipe battery stats (optional)
Goto Mounts and Storage
Format System
Format Flexrom
As we say, be nice, wipe twice.....
Then install the custom rom (not a stock rom, remember the 2 recovery files?)

Well after u fix permissions u boot straight back into cwmand flash the v8 and civatos cm 10 flex, which is exactly what I did after getting it up n running again. edit: no, u need the latest tdv4 - ...I'll post the link for it shortly....
I'd definitely uninstall the Acer drivers and reinstall them. When u connect to yr PC , windows will try to install the drivers....don't let it search windows updates, u have to be quick to cancel it....then it should install the drivers from the acer folder on yr PC which u just reinstalled....is that clear as mud, lol???
One more thought, u could get round all this driver business if u know linux at all....
But will w8 till u get a chance to spend some quality 'tab time'

So, this might seem kind of obvious, but I want to be sure. I found the Recovery-from-boot.p file easily enough, and I found a file called "Install-recovery.sh" in the etc folder, which seems to call another file called "system/bin/sh".
So, do I delete (or possibly just re-name??) "recovery-from-boot.p" and "Install-recovery.sh"? And do I need to do anything with the "SH" file in "system/bin"? (Like delete or re-name?)
Thanks for this much clearer (but still not 100% clear) info about these files. I had read mention of "recovery-from -boot.p" in another post, but it didn't make clear where to find it, just that you needed to deal with it. This excellent post makes it much more obvious which files & where to find!

I was able to follow MD's instructions and installed Re-Flexxx Rom. As to dibb-nz's advice, I couldn't find earlier versions of TD (there was a link that led to some silly software instead - hijacked?). So I reflashed V4 which after the first reboot took me to the setup part fine. However, a second reboot resulted in a dark screen with nothing doing. I tried accessing recovery in vain. I'm not sure earlier TD versions would yield differently. If I recall correctly, V4 only differs from V3 in that TD added XP drivers. Why the tablet behaved thus is beyond me. I intended this superfluous info as a warning to such possibility, however absurd it might appear.
Anyway, thanks to those who came to the rescue, and Merry Xmas to all.

As to dibb-nz's advice, I couldn't find earlier versions of TD (there was a link that led to some silly software instead - hijacked?). So I reflashed V4 which after the first reboot took me to the setup part fine. However, a second reboot resulted in a dark screen with nothing doing. I tried accessing recovery in vain. I'm not sure earlier TD versions would yield differently. If I recall correctly, V4 only differs from V3 in that TD added XP drivers. Why the tablet behaved thus is beyond me. I intended this superfluous info as a warning to such possibility, however absurd it might appear.
Anyway, thanks to those who came to the rescue, and Merry Xmas to all.

can u provide a link 2 the tdv4 u used i will check it.....seems couple folks having yr issue, i wanna make sure the zip isn't corrupt...
ALSO: there are 2 ways to use the EUU -
1) as an upgrade tool - used to upgrade from one HC build to the next - just open and run with usb connected and
2) as a downgrade too - used to downgrade from the ICS back to HC - you run it by not connecting your usb cable and force apx mode
Im curoius as to why folks are getting stuck with the black screen - this happened couple months back too
and tho i have been stuck with it myself - i have never been able to replicate the issue..and believe me when i say i've done some crazy things with my tab in the process of trying... so would like to rule out a bad file...just in case its me causing all the problems, lol....feedback would be appreciated....

I'm almost sure I downloaded from the link provided in this thread, though I'd appreciate your not quoting me on it (lol). I remember downloading twice but cannot tell now which is which. Either way, I "upgraded" from HC 3.1 to 3.2, which is the version included in V4. Beyond that, I'm not sure what other information would help sort things out. Oddly enough, the first automatic reboot after flashing works fine and takes me through the whole setup process glitchlessly. It only happens on the following reboot. You can get into recovery 1.5, but fixing permissions won't do.

ok thanks for that - the v0-v2 required all sorts of jumping thru hoops to get root/cwm installed....when u finished the first flash you would end up with a LNX check sum error in red text on your tab and have to boot straight to recovery and fix checksum errors (not permissions as i said earlier)
v3/v4 now comes pre-rooted with cwm 1.5, which is what may be corrupting things if you are still have the v8 bootloader - altho in saying that, a few of us have been on HC3.01 with v8 and had no probs flashing a compatible ICS v8 rom from there...maybe it was just a fluke who knows...One thing I do know is you should really have a compatible recovery with the v8 - which is why all the flash packages come pre-loaded with a custom recovery....as MD said above you need to make doubly sure your rom/reocvery/bootloader are all compatible with each other. this applies whether they be stock or custom 'whatevers'....

I was initially on 3.1 stock. I went to stock recovery which proceeded to erase whatever, then showed the android belly up with the triangle exclamation mark and so forth (The sd card contained no ROM at this point). I rebooted, then flashed V4 directly from inside 3.1 with debugging on. It "PASS" uneventfully, rebooted on its own to the setup wizard. Things function normally within that capsule (it showed HC 3.2 I believe). I turned it off after setup was done, then on again to experience the black SOD. I then went to Recovery 1.5, erase everything a few times, then rebooted. Same result. Eerily dead.
Then came the V8 Bootloader and Thor V20, and the tablet was resuscitated. Works fine now.

[Q] unbricking selfbricked stock A500

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!!!

[Solved]ACER Iconia A501 3g/wifi TAB - Help with root/ROM install (TimmyDean method)

Hi everyone.
Just repeating again - the model I have is A501 on stock 3.2.1 Honeycomb - a more USEFUL tablet with 3G and WIFI capabilities...One would think it would be a much more popular model, but the A501 doesn't have its own board on XDA; its merged with this board for the less practical A500. Basically, I have created this thread as I don't want to take any 'extra' risks in successfully installing ROOT with the CORRECT ROM with the most updated version of Android available for this tab, for example Jellybean...
Another A501 user, beny9 posted:

Following TimmyDean's method (thank you) I have now managed to install 3.2 Honeycomb A500 ROM with success after completing steps 1-15 inclusive from his README file. As you will know, I don't have 3G or GPS functionality, so I need a stock A501 ROM to install.

Can someone link me the a fully detailed video or post on here on installing the ROM i mentioned above (if that's the best one to go with, given what I'm on now; A500 3.2 and still keeping root), or to install some other A501 ROM which is for at least Jellybean or ICS?

Your best bet is to install a good 501 HC 3.2 and get on HC for your 501.
The files are available. What you'll probably want is a full HC Update rom for the 501. Note that some of these Acer roms are encrypted, so you'll need to decrypt it first. You can find the decrypting tool in the Themes and Apps forum, as a "Sticky". After decrypting, you can pull the update.zip out of it, and copy to Ext SD (do not extract, just pull the update file out). Boot the tab holding Vol- and PWR I believe. Might be Vol+ but I can't remember. This should force the tab to look for update.zip on your SD and install it.
I would use this one;
Acer_A501_1.309.02_4.031.24_COM_GEN1
After it installs, and you get it set up, you need to get Acer Update Enhancer from the Play Store. This will allow your tab to get the ICS OTA.
Keep in mind, there is only 1 official ICS OTA update for the 501, so don't expect more. It may do it in 2 steps though.
If you want root on ICS, there is really only 1 way to get true root and adb system remounts. And that's to flash the V8 unlocked ICS Bootloader, and flash an insecure boot.image. There's currently a small package that'll give you somewhat root, but it's a pain and really doesn't do a good job. So it's better to get the V8 and unsecure boot image. Might be a good idea to also install CWM Recovery at the same time.
Get the correct rom installed first, then check back if you need help.
Oh yeah, one more thing. When you are on HC 3.2, get your UID number and write it down somewhere. You need this as a safety precaution. There's a good sticky thread on how to do it. Pretty simple really.
MD

Ugh. I have a pain in the A$$ version of AVG...even under advanced settings there was no disable options. Managed to figure it out to run the Acer Decrypter EXE and fix the image you have advised I should download and flash. Will give that a go now...
Thanks again!

Keep in mind, there is only 1 official ICS OTA update for the 501, so don't expect more. It may do it in 2 steps though.
If you want root on ICS, there is really only 1 way to get true root and adb system remounts. And that's to flash the V8 unlocked ICS Bootloader, and flash an insecure boot.image. There's currently a small package that'll give you somewhat root, but it's a pain and really doesn't do a good job. So it's better to get the V8 and unsecure boot image. Might be a good idea to also install CWM Recovery at the same time.
Get the correct rom installed first, then check back if you need help.
Oh yeah, one more thing. When you are on HC 3.2, get your UID number and write it down somewhere. You need this as a safety precaution. There's a good sticky thread on how to do it. Pretty simple really.

Hi MD,
I have Acer Iconia A501 tablet. My tablet suddenly showed andriod logo with exclamation mark when it was being used. Upon looking at your posts, I found the resolution which I tried. I am not expert in this all, but I tried running your ROM "41-124-01-A500-update" from one of your posts which was actually meant for A500. This resolved the issue successfully and tablet was up and running.
Then further I found full ROM for A501 as mentioned below and thought that I should try the ROM meant for the model of my tablet.
I successfully decrypted the ROM that you mentioned "Acer_A501_1.309.02_4.031.24_COM_GEN1"
When I tried to update it with the mentioned ROM update.zip, it did updated it from SD card and passed android symbol with those gears running. However, when it restarted the tablet by itself, it showed ACER logo and then it showed "ANDROID" (spelling in blue color) which kept on flikering slowly for long long time....for more than 30 minutes and did not moved further. Can you please let me know whats could be wrong?
I also tried ICS ROM, but that didn't worked (it failed). So after couple of trail and error, I moved back to A500 ROM update.zip which I knew that is installing successfully.
Can you please let me know what shall be done in case I want update.zip for A501? It will be highly appreciated if you can upload update.zip directly that I can use and that gets installed successfully.
Regards,
Muk

Hey Muk, I can probably guess the ROM you installed doesn't do data wipes and such, so it caused an animation loop.
Try this one. It's an SD ROM, so it "should" wipe your Data, along with installing the ROM.
https://mega.co.nz/#!NZBlBSLQ!mOHICp7gbinkYeHCvrEz7aKXsWQjjquAWq_XC_lSQzk
As you probably discovered, Acer has pretty much removed almost all tablet ROMs. I snagged a few the other day, then checked yesterday, and they removed all from their support site.
I would guess they are getting out of the tablet business.
Also, they shut down their OTA Update servers for a few months now.

A big thank you to Moscow. I have tried the above link but still no go.. I have seen on Acer website they have updated the OS but all Android 4.0 ICS and nothing with Honeycomb. The tablet was initially with Honeycomb. Please advice. Thank you and Best Regards.

Hi MD,
Thanks for your super fast response. I am downloading the ROM for A501 from the link provided by me. I will update you if it works in my tab.
I forgot to mention you about one message that I received once tablet is restarted. So, once ROM for A501 from SD card has performed its job successfully....that is that android symbol with gears in its tummy is successfully finished and tablet restarts. It shows "Acer" (spelling logo) and then after it gets stuck at "android" (spelling logo). Between these two, it displays two lines messages on top left corner for 2-3 seconds that the "blob is illegal - abort" and then gets stuck at "android" (spelling logo). I think this might be useful for you to identify something.
Another thing about wiping out the data, in starting when we press volume down and power button, it does display message about SD card (still not not sure about whether it might be wiping out the data or not....I believe you might be correct that it might not be wiping out the data).
Another thing, that I found in my backup is that when I purchased this tab (A501), I downloaded HoneyComb 3.2 Kernel Source Code from the Acer support site. Is this something that you can do magic with and provide me with update.zip? Please let me know....if you can do magic with this, then let me know how shall I share it with you.

Hi MD,
Thanks for your super fast response.
I tried downloading the ROM for A501 from the link provided by you. It downloaded it from the cloud, but at the very end it displayed message "Decryption Error". Still I tried extracting "update.zip" from the zip file, but it displayed message that the archive is corrupt and file is corrupt. Can you please check at your end and provide me with fresh link or directly with update.zip? For your reference I have attached screenshots of errors.

Trouble installing ROM for A501
Hi MD,
Please read my earlier message and then read this one.
Thanks a lot....your answer about my first problem resolved everything.... (your answer was "that the ROM that I am trying to install is not clearing the data"...I verified that the ROM is clearing the cache, but not the user data. I can confidently say that you correctly identified the issue as when the ROM installation was stuck at "android"....I switched off my tablet and tried installing again the old ROM for A500 which I knew that it is working and instead of asking me to configure the tablet (i.e. time zone, date & time setup, etc.) after installation, it simply logged in and started my tablet as usual....that means that when I was trying to install ROM for A501, it was not clearing user data and was then hanging).
Now coming back to the link that you sent me in previous message, I was able to download the zip file successfully in the second attempt. I extracted the update.zip and it did not work. It showed the similar problem of getting stuck at "android". However, with your great answer that you gave me, I cleared the user data and cache manually by pressing vol up + power buttons simultaneously and then when "acer" symbol displays, releasing only power button and turning on and off the lock button. This cleared user data and cache. After that, since update.zip (that you provided) was already in my SD card, it installed the ROM and tablet works perfectly. Thanks a lot....:good:
One question, when it asked me about the zone, it had only few countries like US, UK, etc. I couldn't find Australia...is it because this ROM not for Australia? I understand that this is not an issue, but if you find anything for Australia, do send me.
Another thing, is this HoneyComb 3.2? Will 3G and GPS work in this one?
Do let me know if you can do some magic with HoneyComb 3.2 kernel source code that I have as mentioned earlier.

Muk

I'm mobile right now, so can't go into big detail.
In your settings, about tablet, you can always find info on which specific OS you have. If you indeed have an A501 and the settings tells you that your tablet is a 501, then your 3g and GPS should function.
The only 2 differences between an A500 and an A501 is of course 3g. Also, they use different GPS radios. So you can install 500 Roms on a 501 and vice versa. Just the above 2 items won't work. Also, I believe I gave you a 3.2.x ROM. Getting it to ICS 4.0.4 may be a problem.
I revived my own 501 last night by putting the motherboard in the oven, but now it doesn't read my ext SD card, so I may be stuck on 3.2. Eh, no problem.

Hi MD,
Apologies for very long replies. Wanted to convey the message in detail how I did it so that it might help someone else like me.
Thanks for your response. I have tested it, 3G and GPS is working fine. I believe, before my tab encountered this problem, it was having version 4 which should be ICS. At that stage I didn't had any problem with my tab...I believe it was there for long time.
If you have good known ROM for ICS, please forward me I can try on my tab. If it doesn't work, then will re-install the Honeycomb that you sent earlier.
One more question....when I try to update the system from "About Tablet" in Settings, why it displays message the the "network is poor" and advices to move to better coverage? Though, I am just besides my WiFi modem and coverage is almost 100%.
And @jonnybrave: If you are referring to the ROM that I successfully installed which was sent by MD earlier, then it does not need any decryption. So you can use the link sent by MD earlier in this post. And if you are referring to the KernelSourceCode that I mentioned earleir, then it needs some kind of processing in Linux machine and then you can create some image.....this is was I know about it....sorry not an andrion guru. Please let me know what you are referring to.

You get the message as do all 500/501 owners (it can change depending on version of Rom).
Acer no longer gives updates to any of their devices (regardless of age). These are otherwise known as OTA Updates. So they have closed their update servers, so now we get some "message" that absolutely means nothing.
I suppose Acer is getting out of the Android business and no longer supports anything. Nice job Acer.
As for updating to ICS (or any other version), I have a few update files. Generally though, the update files must be matched to the current version of your tablet. Sometimes you can run a "full update" and it will work.
The problem, is these tablets are getting old, and the nand memory can go bad. Running an update can cause a variety of problems such as "Stuck in APX" mode, stuck at bootloader, stuck at boot animation. Then we have to go back to the EUUS file, or an old SD ROM file. So you run the risk of doing things all over again, and the risk that it just won't work again. (I spent a couple hours last night, and was almost ready to throw it in the garbage)
For example, I'm pretty much stuck at 3.0.x or 3.2.x. I've already disassembled the tablet and put the mainboard in the oven, just to get it back to life! And after numerous attempts to get ICS on it, I've pretty much given up before it hard bricks again. In fact, I can't get a 3.2.x EUUS to work on it, so it is stuck at the 3.0.x ATT EUUS. Eh, it's my little girls tab, so as long as it gets You Tube and browser, it's pretty much ok.

Trouble installing A501 ROM
Hi MD,
I am in the same boat as you...lol...This tablet is mostly used by my daughter and as long as it is solving my daughter's purpose, we are happy
I was just curious about that message as to why that is happenning, but after your clarification, it is clear to me as to why it is happenning.
My tablet is working as normal and everything is working fine...so we are happy with what we have.
Thanks a lot!

Looking to do a stock install of 3.2 on A501
blackthund3r said:
LIST OF FILES
Please note that none of these files are rooted and/or tweaked! They are stock Android ROMs from Acer and designed for stock recovery!
Flashing them will remove custom recovery and/or custom bootloader! You will be fully stock! Update zips may not install if you have modified your device in any way. If unsure use a full package! You need an EUU package only if your device is bricked as it will be completely wiped clean in the process!
-----------------------------
I am looking for the 3G version the 3.2 stock ROM to do a fresh install on my A501
The link from Vache seems dead.. can anyone please help to provide that particular ROM?
Thanks a lot. Desperately need some help as I'm password locked out!

Best to just get stock ICS. Why are you password locked? Is the device stolen? I can easily help you get past it but I'm not sure whether I should.

Thanks blackthunder. It's our personal device, my wife set the password some time back and is sure she hasn't forgotten but for some reason it's not being accepted. We can't figure out why! I have the original receipt and box etc in case anyone's interested!
I tried the stock ICS Rom by naming it update.zip and rebooting into recovery, but that gets stuck at the Android guy logo immediately. Also tried 3.2 before that via a link from this page, and that seems to work until the progress bar hits about 80%. Then it just reboots back to the dreaded locked screen. From what I understand I can only do a reinstall of the same ROM version that's currently installed? We have a password lock on it, and not pattern. Would highly appreciate any help. . Really want this thing to start working again. It's practically new [emoji20]

Guys any idea? Really desperate here. Thanks in advance!!

Your beat bet is using an EUUs package to wipe the tablet and reset back to 3.0.1 then use Flash Tool to get CWM or TWRP + a decent ROM

To install EUUs, is it the same process; rebooting with power+volume and flashing via SD card? What version EUUs do you think I need, currently I have 3.2 installed. Is there a guide for above?... will be a lot of help. Many thanks

Actually, even easier.....use the APX Flash Tool to get yourself a CWM Image (you'll need your SBK....there's a fair few guides on obtaining this) then do a wipe data/factory reset within CWM.
From there it's fairly easy to side load the latest Acer ROM.

Thanks. I'll try it out over the weekend! Appreciate your help!

God morning! For the apx tool, I'm not sure if USB debugging option is selected, never ticked that myself consciously. Is it OK to go ahead?

Tried using the apx tool after downloading the Acer USB drivers and in short no luck.
Had to go the manual route for flashing since I don't have USB debugging enabled.
Tried two packages, one honeycomb bundle 6 and then also tried a later one for ICS.
It goes thru the motions enters APX mode with confirmation as well on the tab screen, without any hiccups right to the end. But then reboots to the old dastardly lock screen asking for password!
Any ideas? Already backed up using mobo app so am OK to wipe clean and start anew.

Options for upgrading an Acer A500: Acer_A500_4.010.15_COM_GEN1
OK, heres a totally noob question. I have an Acer A500 I bought used. It has been rooted apparently. Has the ClockWorkMod bootloader installed, v5.0.
My question is, what are my options to upgrade this tablet and is there a thread with instructions on which firmware files to use, how far can I go with upgrading the A500 (ICS?). Not really looking to trick it out and go the whole mod route, would be happy with stock firmware, just looking to make it a little more up to date and, above all _stable_! The main issue I have with it now is the wifi craps out every month or so and I have to do a refresh and wipe all info and start over.
I used to get prompted to install a system update, and every time, it would fail with the dead Android dude on his back....so sad. Now, it just tells me, "Network Coverage is poor, please move to a location with better coverage". I am sitting right beside my router...
Here are the relevant specs:
Model number: A500
Build number: Acer_A500_4.010.15_COM_GEN1
Kernel version: 2.6.36.3
If you need any other info in order to help, just let me know.
Thank you very much in advance for any advice!!
