Had installed the stock 4.0.3 on my A500. When I wanted to go back i came accross this thread, and tried to go back to 3.0.1 as described in Option 2.

After following instructions, I get the message after starting up: Boot verified failed..... (On the black screen with ACER displayed in the middle.)

What can I do now to get a running A500 again? (Except for buying a new one...)
[Acer Iconia A500] armada786:
Well, the obvious course of action seems to be Method 1, since 2 failed. It's not as hard of a process as it seems at first.
[Acer Iconia A500] CheopsChefren:
Isnt possible. For that to work, I need to have a running A500. But it doesnt start up, it stays on the screen with the "Boot verified failed".

So impossible to use option 1.
[Acer Iconia A500] wolverine423:
Use usbdeview http://download.cnet.com/USBDeview/3000-2094_4-10614190.html. NOTE: You must have plugged your tablet into the computer you are using this on, either when you run it or at a previous time, in order for it to show up.

When you open usbdeview, sort the list by vendor id.

Look for "0502" in the vendor id column. Find the one that has a 16-digit code under the Serial Number column. There should be a different one than the 0123456789ABCDEF that you get from Thor's ICS.

I used the EUU earlier. (EUUs_SBK_Acer_A500_1.016.05_COM_GEN1) So here are some helpful hints. All this information is posted around here, but I know how people dislike searching.

I put the uid in the CPUID.txt, after 0x0, in the EUU folder (after unzipping it)

In Windows 7, when you open up PBJ20UPGRADE.exe right click it and click on

Run As Administrator

Don't plug your tablet into your computer until after the dialog pops up telling you how to get into APX mode.

Follow directions listed in the dialog box. (Will be after it tries to search for the current image version.)

When the EUU asks for you CPUID, put a 0 in front of the UID you retreived from USBDeview
[Acer Iconia A500] Sanien:
Yeah struggling with downgrading myself but if can always rename the leaked Stock 4.03 ROM to update.zip and put it on the SD card.

Flash it that way works fine.... you are then back on ICS 4.04 locked and stock but it runs until we can figure out how to downgrade easily

---------- Post added at 12:49 PM ---------- Previous post was at 12:29 PM ----------

In USBDeview I get a serial which is the exact same as the one I get from "Status" in ICS developer menu. I also get another ID that looks right but neither works in EUU.

with or without 0 in front? Surely Im doing something wrong.

Fool for not saving my UID :-D

Doesn't work
[Acer Iconia A500] terrormattie:
It just keep saying: Please download the newer image for the upgrade
[Acer Iconia A500] ZsDaniel:
Put it manually into APX Mode, then wait and it will start.

APX: Turn off Tablet, Hold Reset, Press Power for 3 seconds and still hold Reset, Release Power and still hold Reset for one more second, Release Reset

[Acer Iconia A500] wolverine423:
Like I said. DO NOT plug in your tablet until a popup comes up.

If it finds the current image version, it is because you PLUGGED IT IN TOO EARLY!

---------- Post added at 02:01 PM ---------- Previous post was at 01:58 PM ----------

Worked for me. In the CPUID.txt delete what is in there, and enter 0x0(your uid here)

Then when is asks in the EUU, put the uid in with a 0 in front of it.

Hope that helps.

[Acer Iconia A500] drkalo:
Seems like you don't have CWM installed. What firmware version you were running before that? Are you able to boot into Honeycomb 3.0.1?

If yes - boot into 3.0.1 ROM, root it by using iconiaroot, install CWM and then you'll be able to boot into CWM, wipe all and install the ROM of your choice.
[Acer Iconia A500] droiduzr2:
..?

I don't know how you people got it to work.

Once you flash it to the unstable HC 3.0.1, you cant install IconiaRoot because you don't have a file manager. You cant get on the Market either because a Force Close comes up once the keyboard comes up. The Force Close closes the keyboard making it unable to type. You cant mount USB storage. Your Iconia will show up on your computer but you aren't able to copy anything or see anything on it.

Here's what I had to do:

1. Flash it to the unstable HC 3.0.1

2. Hard reset my device (using the guide on this thread)

3. Get on the Market

4. Install ES File Explorer

5. Navigate to IconiaRoot.apk

6. Install it

7. Hit Root and wait

8. Go back to the Market

9. Install Acer Recovery Installer, NOT Acer ROM Flasher (another app there).

10. Open the app and install Thor's CWM

11. Hit Reboot into Recovery

12. Wipe cache, Dalvik cache and install zip from sdcard (ROM)

13. Wipe cache, Dalvik cache and do a full wipe

14. Boot up the ROM (first boot will take a couple of minutes)

15. Enjoy!

I'm still unrooted

I cannot get either method to work. I've tried it everywhich way I can but no dice.

Method one insists I have entered the wrong CPUID (when it is correct every time AND I am following the procedure to the letter) and Method 2 gives the same error as I mentioned here.

I'm tearing my hair out trying to work it out as I've been trying to get my A500 rooted since late last year. Someone please help! :(

Edit: heres a quick snap of my version number if its of any use....
[Acer Iconia A500] stressfreesoul:
I hate being made a lier. Damn it! Method 2 has suddenly decided to work after all this time. I'm curently downloading one of thors ROMs....

[Acer Iconia A500] drkalo:
Cool! So, you scared your tab exposing its bad behaviour to xda...so it decided to give method 2 a go :D
[Acer Iconia A500] caanda45:
Tried timmy deans method did not work, then tried method #2 here worked like a charm!!!!!
[Acer Iconia A500] bengar:
Hi Everyone

I'm trying to install the 3.0.1 version using the method 2. I am doing this because the A500 was locked after playing in the security area with the 3.2 version. The A500 was requiring the user and the pass and the owner "forgave" both, I did the downgrade successfully but the A500 still requiring the user and the password.

Any help will be appreciated

regards
[Acer Iconia A500] drkalo:
Try method 1 or use TimmyDean 's tool which is basically the same, but the firmware you get is 3.2.1 stock rooted which actually spares time :)

The tablet is not encrypted isn't it?
[Acer Iconia A500] bengar:
drkalo

Thanks for the replay, the tablet just is asking for the user and pass, I was looking some way like install a stock to start from the beginning. The method 2 worked for me but as it leaves the data intact the lock ( ask for the user and pass) can not be disable. I have done a root to this tablet but I make the mistake to don't install CWM.

Okay I will try the method 1, and let you know. Thank you very much.

Regards
[Acer Iconia A500] r4ph:
Thanks for the guides, really needed it today.
[Acer Iconia A500] nolanta:
Okay, so I used this tool to successfully downgrade to 3.0.1.

If I followed Method 1, and stop at Step 6 (don't root, don't install Thor, don't flash rom) why does System Update tell me "No Update your device is up to date." when I'm still on 3.0.1?
[Acer Iconia A500] drkalo:
Well if you want completely stock unrooted ICS with ACER's bootloader and no custom recovery just flash the update.zip from here:

http://xdaforums.com/showthread.php?t=1524736

It will overwrite your HC bootloader and recovery.

If you need stock ROM but rooted with CWM, visit this thread:

http://xdaforums.com/showthread.php?t=1633907

I never tried to update OTA after downgrading so I cannot tell you the exact reason why it is impossible.
[Acer Iconia A500] nolanta:
If I follow that link and do the stock ICS/recovery, will that put me back on the path for OTA's in the future?
[Acer Iconia A500] nolanta:
I followed that guide and now I'm on an ICS, but they state in that thread that I will not get OTA's.

I could not for the life of me get method 2 to work. but i did finally get method 1 to work. i had to download the drivers from acer as the included drivers did not work.

[Acer Iconia A500] AndroidGraphix:
Okay, THank you. I have downgraded the ROM and have root access; however, I really need someone to point out how to adb push itsmagic. What is itsmagic? A recovery? a File? a recovery file? I'm very familiar with adb but I've been searching threads for 45 minutes now trying to find, "itsmagic." Every file I download such as: update-recovery-thor2002ro-rev1.6_v2.zip doesn't have itsmagic inside the zip. Any help would be great. Thank You!

Edit:

I should also point out, I've tried the apk from the market to install recovery but it FC's every time I load it.

Edit:

I figured it out. I search itsmagic for all the forums since it wasn't a link in the OP and found itsmagic file. I then made the mistake of thinking I had the option of either doing steps 1 or 2 when in fact I needed to do both! In any case, thanks for your tutorial. Getting ready to go into CWM and flash a ROM!

Edit:

Okay, why on earth does it require volume UP and power to get into recovery instead of volume down? THIS IS WHY IT's TAKEN me 30 minutes to get into recovery!!

stupid encryption and reverting to stock/factory

[UPDATE] I don't know if I missed the "fine print" or something in other posts pertaining to the EUUS method, but thanks to @jazzyjames for the hint as to how to finish that procedure.

YOU DON'T connect your tab until after the EUUS has tried to detect it and finally popped up a little window (as per this thread) http://xdaforums.com/showthread.php?t=1516012

So thanks all of you, but finally got it to go back to 3.01 ENCRYPTION-FREE

YAY!!

[/update]

hi guys, Thanks for all the great work.

A little help, please.

I'm not a computer n00b, been playing with this stuff since the days of the Vic-20. (if you don't know what that is guys, it's less powerful than whatever tablet or phone you've got lying around)

I had my Iconia a500 a couple of weeks before work required me to "slave" it to our exchange server. In that time I had rooted and installed Thor's recovery, and the Acer Recovery installer, but never had time to install a custom ROM. Then Exchange forced encryption on me, and I've never been able to do anything with the encrypted /data partition since.

So I finally talked my boss into de-auth'ing it from Exchange, but now the damn thing is still encrypted, requiring the PIN halfway thru the boot sequence, and the pin-locked home screen.

So I've tried Option #1 in the TUT, no go...

I get a "download newer image for upgrade" from the euus, and no other option but a "quit" button.

#2 frankly scares me a little :D

I'm a working stiff with a family who can't afford new toys very often.

[edit] BTW, my goal here is to wipe it and start from scratch. I'm presently on stock OTA ICS

Has anyone else had this kind of problem?

when I boot to recovery, I can't mount /data or format it.

when I try to do a factory reset from within settings or from recovery, I just end up booting back into my perfectly preserved junk that I wanted to format, along with all the required PINs and passwords.

I cannot wipe this thing?!?

help? LOL

I've seriously been reading the forum for over a month, whenever i get the time, and this thread is the closest I've found to my problem and/or what i want to do.

If more details are needed, I'm more than happy to give them.

Thanks guys.

[update] found some other threads pertinent to this and it appears to be because I no longer have the original bootloader. If I flash the stock bootloader from fastboot, I may be able to do a factory reset properly. can anyone confirm this from experience?
[Acer Iconia A500] dibb_nz:

Hi guys, I'm new to this forum. Saw this post and was wondering will this work on official ICS stock rom? I just want to revert back to HC because when I updated to ICS through OTA I've been having SoD every single day. :crying: Did factory reset, still SoD even with nothing installed. My A500 worked like a charm when it was still on HC, just after I updated to ICS then SoD problem came. :( So far I haven't do anything to my tablet yet, it's still not rooted and no custom roms/kernel in it. So will this work on a non-rooted official ICS stock rom?:confused:
[Acer Iconia A500] drkalo:
You're on ICS stock bootloader and you need to use After OTA tool by gersma. This thread is quite obsolete and is for reverting stock HC 3.2 back to 3.0.1.

p.s. Don't forget to backup all your tablet IDs before flashing anything.
[Acer Iconia A500] jasenlee1984:
Thanks but if I'm not mistaken I need to get a official HC stock rom first. I saw vache's full package thread and I don't know which one is compatible with my tablet. My A500 build number is Acer_AV041_A500_1.031.00_WW_GEN1 any suggestion:confused:
[Acer Iconia A500] drkalo:
No, you've updated your official HC OTA to ICS - haven't you?. So - no need to do that. Using OTA Tool, you can root your tab, install custom recovery and later flash whatever ROM you like.
[Acer Iconia A500] jasenlee1984:
Yeah I updated from official OTA. Since now I'm in stock ICS bootloader and if now I want to go back to official HC stock rom. I know I will need a HC bootloadr in-order to do that. So can i just install the Bootloader HC V3.01 + Recovery Thor V.1.7.3 from AfterOTA, then root my A500 and simply flash back to the HC stock rom I've downloaded? Please correct me if I'm wrong. Thank you.

The reason I want to go back to HC stock rom is because I've been having sleep of death issue after I updated my A500 to ICS through OTA.

My apologies I didn't read your whole message. It took like 20 minutes. So it basically goes through the whole process and get's stuck at trying to load the image onto your tab to flash it? Make sure you running as an admin on your pc and if you are. How about microSD card. Not sure if you need one in there for this process. But I have a 32 gig FAT 32 formatted one in there. I remember seeing that 3.2 supported NTFS cards. If you did format it to NTFS try putting it to FAT 32? My gut tells me that you don't need a card inserted for this. But otherwise make sure you have plenty of free space on /sdcard.
[Acer Iconia A500] ve6rah:
I have admin rights, but I'm not the user "administrator", I have access to 3 computers, the one I tried this from (running XP) my desktop (running ubuntu) and a laptop (macbook air running OSX)

So I don't really have much other option right now...

As for a "usb issue" the computer can see the current running version on the tablet, it can put it in to APX mode, and I'm capable of transfering files myself, so I don't think it's the USB that's the issue.

Just a quick (newbie) question...

After I made through downgrading to 3.0.1 (from OTA 3.2), what's the next thing to do to get to 3.1 and get the rooted 3.2?

Can someone give the added step-by-step tutorial here.

Thanks.
[Acer Iconia A500] GamezR2EZ:
This would be alot easier if everyone just used the image vache posted for 3.0.1. That image WILL work for the locked bootloader. After you get back to 3.0.1 you can then root it then install CWM.

OP please update your guide, that is the much easier/safer option.

EDIT-

The actual link has been update. I pointed you to the wrong file previously

http://www.megaupload.com/?d=GR57P1NN
[Acer Iconia A500] drkalo:
That's method 2. Would you like me to remove metod 1?
[Acer Iconia A500] GamezR2EZ:
No that still uses an EUU.

The zip in my previous post is an update.zip FROM acer specifically to downgrade from 3.2 to 3.0.1. It will work after you get a locked bootloader.

After you do that iconiaroot would work, but there are other ways to root 3.0.1 as well. Anyway, it seems like it would be easier and quicker and platform independent.

Try it out
