hey guys I've been searching for hours and cant seem to come up with a way to flash the stock bootloader for the A500.
I've got skrilax cz's v8 with CWM recovery v5.5.0 thore2002ro and want to go 100% out of the box back to stock. Is there anyway some one can point me in the right direction or give a little instruction. (its been years since ive worked on this and I'm filling a little noobish)
I've been working with afterota v1.09 because I actually still had it on my computer and it seemed like a good bet but I can't seem to get it to boot into apx mode I've uninstalled and reinstalled the drives I've got to be missing something.

Hello!
I was about to unroot and get back to stock with my A500 so I flashed a stock ROM via CWM to get a ota-update. Before i had a custom ICS ROM installed and now I installed a HC stock ROM. The problem is that i forgot to go through the wipe menu in CWM before the flash and now when I start up my tablet I first see the ACER logo as usual, then a android text-logo which the tablet is stuck at. I've waited 20 minutes and is still shows the same thing. The logo has an animation which i still can see. I've tried to restart the tablet and get into CWM again without succes.
I have read diffrent threads for several hours but I can't find my problem. What should I do? :crying:
what does the android text say?
Hi dibb_nz.
It is the bootanimation from what I gather (Video; http://s1142.photobucket.com/albums/n602/JdgM3NT4L/?action=view¤t=AndroidBootanimation.mp4). I am trying to help someone get a tab up that is doing the same thing as well. The weird part is that recovery is good, bootloader passed (V8), wiped data/cache/system. Tried three ICS roms so far, and every one is stuck at the bootanimation. About to go bonkers trying to figure it out. The only thing that I can think of to try next is changing CWM from Thors to TWRP or something...
To Webspirit, your problem will most likely get fixed by using blackthund3rs APX Tool. Google it and then goto the forum where it is. There's plenty of support for getting that going and you shouldn't have any problems. If you do holler. Alot of us have had to use that tool and can help. I am hopeful that yours will be as simple as downloading and installing recovery back and flashing a nice rom.
Yeah i agree with the guy above me, your going to have to flash something from apx

hi J...ok thats cool re boot anim...i asked becoz like u i been trying to help a couple of others who can't use any of the flash tools or roll back to HC...i only just got myself fixed after being stuck in apx, no recovery, and boot screen saying in red text "reboot device" thought he may have had similar issue....
J...have u used nvflash or apxflash to roll back - theres a few folks getting stuck with it...its loading the HC apx driver which aint working with the ics bl so then yr tab gets stuck in apx!!!
I started a new thread hoping someone can help us all out be great to hear yr thoughts on this....its driving me up the wall
sorry didnt mean to hijack the thread
I can list any number of things that I've done/tried, but there have been so many! I'm not a noob when it comes to flashing ROMs, but I'm a new to the Acer Iconia Tab A500 and that's the problem, I think.
Anyway, I got the A500 with Honeycomb and I let it do the ICS OTA. No problem. Then I rooted it. No problem. I got to here: http://forum.xda-developers.com/showthread.php?p=31546261#post31546261
Then I decided to change the bootloader and that's when I borked something up. It would still boot into ICS just fine, but I couldn't get into recovery. I decided to try downgrading to Honeycomb 3.0.1 using the "unstable" update.zip, but that just ruined everything as now I'm completely stuck. I can't boot at all, it just hangs at the black screen with white Acer letters and red "boot verification failed" in the top left corner. Recovery gets me the dead Android image with the black exclamation point in a red triangle.
I have looked all over and I've read dozens of XDA threads...and I'm sure I'm missing the one thing I need to do to fix this, but heck if I know what it is. I have the Acer drivers installed on my computer, I have a variety of tools (nvflash, blackthund3r's apxflash, etc) waiting to be used if necessary.
So, please, I implore you...treat me like I'm dumb and walk me step-by-step through whatever it is I need to do to get my A500 back up and running! Thanks for your help!
UPDATE: Many hours later, I fixed it! I did another update using the full, stock image of Acer_A500_7.006.01_COM_GEN2 (just guessing about whether it would work or not) and it seems to have done it. Sure, I'm back on Honeycomb 3.2, but it worked. And then I was able to use AfterOTA to root and get the CWM bootloader on there.
So my next question: what do I need to do in order to get ICS? Can I just flash an ICS ROM from CWM, or do I need to update the bootloader in some way?
Thanks!

Yes and No.
Now that you are on HC 3.2, you're going to need to do the process again.
IE: Unlocked Bootloader and CWM
The problem you had at first, is that when you flashed the UNL bootloader and CWM, you missed 1 tiny step. (lot of people forget to do this) And that is to delete the boot-recovery.p file from the /System. If you do not, you can install CWM, however, when you boot into stock ICS, your CWM gets overwritten. Another little trick from Acer
In the Dev Section, in the stickies part, Civato posted a link to a full ICS Stock Root Rom, With all the nasty stuff removed. (bootloader, recovery files). Download it, put it on your Ext Sd card.
http://forum.xda-developers.com/showpost.php?p=31572588&postcount=6
Then do the unlocked bootloader + Cwm again. Only THIS TIME, when it finishes, boot the tab immediately to CWM (vol- and PWR). And install the modified stock rom, or one of the custom roms.
Don;t forget to get your HC UID number written down before starting the process. Also it's good after ICS to get your ICS UID number also written down.

Hi there!
I own an Acer Iconia A500. Originally came with HC3x, updated it all the way to ICS. Rooted it at ICS with this method:
http://forum.xda-developers.com/showthread.php?t=1546593
Worked fine. The only issue is accessing Recovery at boot. (Just in case I plan on restoring the Stock version of Android, for warranty).
I first used the Acer Recovery Tool app at the Play Store. I tried one of the Recovery options listed. CWM for start. Backed up as asked, then rebooted into recovery. I was told "recovery verified failed". Did a restore, tried another method, same crap, with a time the bot with the (!) appears. Did some research on the issue, and came up to this thread:
http://forum.xda-developers.com/showthread.php?t=1622425
I did option 1 (Afterota v1.09). And flashed Recovery Twp 2.1.3/Bootloader.
I reseted back to bootloader, it didn't show "Recovery verified failed", but instead I got the bot with the (!) again. Went back to Acer Recovery tool. Bottom shows that its unable to identify the installed recovery. So I tried TWRP 2.1.3, didn't work.
My question is, how can I get this to fix? This is my first time trying to install a bootloader. Please help me step by step to get this situation fixed. I appreciate the help by any!!
i am having the same issue and have tried several different fixes without success... any suggestions would be greatly appreciated!
(the only one I haven't tried yet is 'manual flashing' outline here http://forum.xda-developers.com/showthread.php?t=1622425... will give this a shot when I get a chance and report back... from all the 'automated' or gui methods it always seems to get stuck at the flashing/copying stage...)
thanks!
Same issue...
Glad I'm not the only one with this issue... Used the exact methods you did, same results. Amazing!
i think part of the problem may be that the bootloader was not unlocked when the initial recovery was flashed? when i rooted i thought I had properly unlocked the bootloader as well, but perhaps not....? (... i thought i read somewhere that if the bootloader has not been unlocked when you flash recovery these are the results.. so i am assuming that this might have something to do with the issue?)
the question is, is there a fix?
i have been playing and experimenting more on the tf101 side... all the stuff i'm doing with this is for my wife's a500 because she liked some of the features on my tablet... i'm not all that familiar with the A500 (didn't have to deal with bootloaders separately on the tf101) so any help is greatly appreciated!
thanks!
Alright. I seem to have got it all fixed. What I did was, went back to this page:
http://forum.xda-developers.com/showthread.php?t=1622425
Went to the "Automated flashing tool" / "USING blackthund3r ATX flash tool , It makes it all a little easier !" Method (below Option 2, in the middle). Downloaded V8-TWRP_2.1.3_ICS_recovery.a500apx and APX-FLASH-Tool & Manager, and followed the instructions.
It didn't work with Windows 8 RTM, (driver issue with APX), but Windows 7, worked perfectly, after downloading the Acer driver from a link in the app when prompted. All worked well.
hope u guys got sorted....
for others reading this
to install recovery from ICS you must first flash the unlocked boot loader, after that u can use Acer recovery installer, although once unlocked most of us use fast boot or the auto tools to do it
Ok here goes. Sorry for the long post but I want to give as much info as possible so I don't leave any of you in the dark about anything. Been working on / researching this for four days now to no avail.
My A500 which was running ICS 4.0.2 just randomly bricked itself one night, so I downloaded EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 from here. It worked, but I really don't want to stay on HC 3.0.1 so I decided to go through the updates. It updated great, HC 3.1...3.2...then when the ICS update came along BAM it bricked itself again (stuck on Acer loading screen)
So, I decided I might as well root it, since I've always wanted to. Ran EUUS again to reset to HC 3.0.1 then ran gingerbreak. Installed Acer Recovery Installer and used Thor's recovery 1.7 I believe it was. Booted into recovery and tried to install update.zip from the STOCK Acer_A500_7.014.16_041.206.01_COM_GEN1.zip I downloaded and BAM bricked again...my tablet doesn't like ICS now all of a sudden? Strange...
I then downloaded NVFLASH from here and installed skrilax's V8 bootloader w/recovery. Booted into recovery great, wiped the partitions etc. and tried to install the same ICS update.zip. BRICKED again!!!! Back to the drawing board...run EUUS...3.0.1 again...
So after days of working on this I decided maybe my Tab hates ICS now for some reason unbeknownst to me. Not very rational (lol) but anyway. I saw the JB ROM that's been put up http://forum.xda-developers.com/showthread.php?t=2239476&highlight=rom+ics and figured heck, why not, maybe the ICS ROM I have is corrupt. So I used NVFLASH, Skrilax's V8, and flashed the ROM...bricked again
I think the only thing I haven't tried is
I think I'm going to go crazy now.
Please help, I'm at wit's end.
More info:
I have acquired mmcblk0 (renamed to mmcblk0_start), my CPUID, and my SBK
I enable USB Debugging and Unknown Sources every time.
I have Windows 7, but also have UBUNTU installed on a Virtual Machine if the need arises.
Oh and I've booted into fastboot mode and run Babsector as well which did not help.
Hope I didn't miss anything. My brain is tired from working on this for so many days. I really want my A500 back! Either JB or ICS & rooted if possible!!!

Wow I thought I was the only one who had this issue. My A501 was working fine on Evil-A V2 (4.1.2) for many months and decided one night to crash and now stuck on V8 boot screen. Ive tried everything however I can get it to boot up on a 3.2 update.zip file.
The only recoveries I can get to work are TWRP 2.5.0.0 (on secboot)
Now I cant get it to flash anything other than 3.2.
It is formatted with ext4 partitions
whenever I try to flash it reboots to ACER download screen but the flashers wont get any further than that. (loads Acer boot recovery driver ok)
Any ideas?
Nice to know I'm not the only one. I hope we get some answers!!
*sigh* My situation has gotten worse. Now TDv4/EUUS won't roll back my device and my tab won't go past the recovery bootscreen (Just says "TEAMWIN" on the screen) That is the ONLY recovery that NVFLASH will flash to my device now, for some reason none of the other recoveries will go back onto it.
My stress level has gone up 800% from working on this. I don't have the money to buy a new tab. I really need to get this one working again.
:crying:

I think my MB is failing/has failed. Either that or something I flashed to it was badly corrupted.
Now my tab has stuck itself in apx mode, bootloader won't load, recovery won't load, every program I have (nvflash, TDv4, EUUs, Babsector, etc) fails. Babsector gives me the fatal error "command 12 NvError 0x120002" and "setting device: 2 3" which I've read means that the tab is shot. Adb.exe tells me the device is not detected, even though all the drivers are installed correctly.
I'm pretty bummed because I don't have the money to buy another tab at the moment, and I used it ALL the time, took it everywhere with me.
On the up-side, I've done some research and it seems if you disassemble your tab and sell the working parts (things like the screen, metal back panel, internal speakers - obviously NOT the MB though!) individually on eBay you can make a bit of your money back.
Can anyone direct me to some good links/video tutorials for dis-assembly?
whoops... I just started a new thread with a very similar issue... My tab also just involuntarily bricked itself... I've made some progress but it's still in bad shape... I don't know about you guys but I had been running at a steady 50% overclock; do you think that could have led to this?
Sorry Man
No @rwilpstra....my a500 is overclocked to 1504 ghz and it runs just fine......as for you pareeeee....Sorry man.....your device is gone....no apx...no fastboot....no recovery.....it's beyond minor corruption....it's like you somehow managed to corrupt every single part of the memory and every partition that there was on your device....you're better off disassembling it.:crying::crying:
Sorry to be a bother but I'm hoping someone can point me in the right direction.
Quite a long time ago my a500 had an issue where it was rainbowing on boot. It remained in that state until I picked up a Nexus 7. Back then I attempted to recover it and I was able to get a bootloader installed, after I got the bootloader working (TWRP) I was not able to get any roms to boot. From there I just let the thing sit around gathering dust. Unfortunately all the specifics are a bit fuzzy for me. But I've read quite a few posts and have tried to figure this out on my own but I haven't had any luck. I would like to get any rom booting and just move forward from there. Any help would be greatly appreciated. Currently I am only able to boot into TWRP v2.1.3 or I can just sit an an Acer logo that never progresses any further.
I have pretty much all the tools one would require to fix the problem I just need someone to point me in the right direction. No data on the tablet is critical fyi.
Try Nvflash the bootloader and then install a custom rom.... but my A500 can't even get the bootloader

Do you have the skrilax_cz unlocked bootloader installed? Should state so (with version) when you boot the tablet.
