[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

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

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... I'll look around for the Linux commands/packages. Maybe someone who knows this stuff will notice and share. (Please.)

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?

yeh i'm linux illiterate m8 but from what i've read its a lot easier than mucking about with windoze drivers!!!
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'm about to try it all over again and find out for sure...man i'm a masochist....or just plain stoopid, lol

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!

I just now noticed that you mentioned this. What a nice alternative.That's going to be a big deal for some people to get out of a jam fast.
Nice find.
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.

big ol' noob here. i just flashed the Jelly-Bean_4.1.2_CM10-FLEX_v6supercharged_Aroma rom on my a500 which previously had lightspeed 4.8 on it. now when it boots it shows the android guy with gears for a second then just a blank black screen. the backlight is on so you can tell the tablet is still on. i can still get into recovery with no issues though("aman ra-iconia-3.17-ics" via "scrilax_CZ bootloader v8") i dont know what it could be though. installation of rom gave no errors. so please, I ask for assistance in resolving the issue. i was looking into (and learning about) fastboot fixes but i'm not sure if it applies to me nor have i tried it before. any help in fixing the darn thing would be much appreciated.

You should change the title to "Stuck in APX Mode". Refine your search. I've never had the issue, however, I believe 1 or more partitions are messed up. Which means you will probably have to revert back using TimmyDeans V4 rollback tool at the worst.
Just a guess. But search the forum for those terms. You should be able to find some threads as I've seen several references to being stuck in APX mode.
One place you may want to post your issue, is Skrilax_CZ's bootloader thread. He may know some fastboot commands to wipe the data.

cool. I'll do that. thanks man. I'm still learning the lingo so that sheds a bit of light for me and gives me some direction to start. thanks again.

Also remember, before you install a different rom, you must; in CWM
1. Wipe User Data/Factory Reset
2. Wipe Cache
3. Wipe Dalvik
Then go to Mounts and Storage and;
1. Format System
2. Format Flexrom
Then you can install the rom. If you haven't done this, you should try again.

Try the wipe commands suggested in post #4 and then reflash your JB ROM. A lot of time it helps with reflash the ROM after wipes.
thanks for the tips. i believe i've actually performed them like you guys told me but it seems i've made it worse. my ridiculousness is currently going on in this thread here
I'm having the same issue with this ROM. I'm using the same recovery you are.
if you have any progress let me know cause i'm still stuck in apx land...
final update
Back to stock HC 3.2.1 right now. my issue ended up being unable to format the /data directory causing all my newly flashed roms to not load properly. per JdgM3NT4L's guidance i used the tutorial and tools here which took me back to a working status. now my only problem lies with what delicious rom should i have next? an ICS or a jellybean? if any XDA tutorials or assistance help bring you tablet back, make sure to click those ":good: thanks" buttons guys.
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:
