I just followed the Method 2 even my battery was 55%.

My Tablet is now back from Factory Setting.

It took me 10 mins to do it (after thinking for at least a day to decide to do or not) and now from unrooted 3.2 back to 3.0.1 and now, already rooted and will continue the process later when I get home.

I'll be waiting for the tutorial on step-by-step how to achieve the rooted 3.2.

Thanks for drkalo for the updated post on page #1. - and Yes, please remove the Method 1 because it's very easy to do the Method #2.
[Acer Iconia A500] jyams:
Me thinks you just need to download one of the 3.2 roms with a kernel and wipe and flash through CWM. I have had my a500 for several months but finally took the plunge yesterday and left the stock 3.1 behind. Was rooted but never had left the stock install. So, went with Taboonay 2.1b (Honeycomb 3.2) and Richard Tripp's 3.4 kernel and am very happy. Running at 1.5ghz overclocked and smooth as butter. Also did the Asus Transformer Netflix patch and Netflix works great too! Be sure to use this version of the Netflix app. Liking this alot, plus, not waiting on Acer to send us a 3.2 update that can't be rooted LOL:).

Success on Downgrading, Rooting and Installing Taboonay 2.0 ROM

I think there's no need for my requested tutorial.

I managed to make my ROM installed after downgrading to 3.0.1 and now, I'm using Taboonay 2.0 after I flashed and wipe some couple of memories and others.. then installed it and after a few minutes, VIOLA! I'm now Taboonay ROM, v3.2 and Rooted!

Here are some screenshots of my tablet:

PS. Edit : It works after some fiddling around.

what i did was deleted ADB file in temp and deleted if there was a second process. and then the process started. now im on taboonay 2.1b super fast than stock 3.2 and many features. especially now i have root :) thanks to all the devs for making this happen

Root install prob

1st many thanks for this idea.

This is what I have done:

1- copied the update.file to the ext sd

2- off and on the iconia with volume (-) then update process completed in 1-2 minites

At the end no way I could intall root.

Also I had message error "android.process.acore"

4- to get rid of this message I get an update.zip file from ROM 3.1

5- Updated the iconia the same as above. The problem disappeared.

But unfortunately I still could not root and this is big issue now.

Any help?

Thanks again
[Acer Iconia A500] GMC7000:
As someone who just bought their A500, came home and updated it to 3.2 without reading about it online, thank you!!

Being a longtime owner of an Xperia X10 phone with their tighter-than-fort-knox bootloader, you can't imagine how frustrated I was to go online and find out I had just inadvertantly locked the bootloader on my Iconia. I used the first method (the second method mentioned gives the file, but being somewhat new to all this, I wasn't quite sure what to do with it once I had it) and it worked perfectly. Now I'm going to see if I can overclock this thing.

EDIT: After I figure out how to root it, that is
[Acer Iconia A500] kekinash:
I used yesterday the file to revert back my iconia without problems. It worked and I was able to root the iconia again. My steps were:

Use the file to revert back the iconia. I didn't allow to reboot after the flashing, and I flashed the stock US 3.1, after that I let it boot and I was able to root again. So maybe the trick is not to let the update to reboot the tablet and flash the 3.1 OS version immediately.

By the way I'm again on 3.2 stock unrooted, I don't feel I need to root it right now. The only thing I hate is ads, but most applications I have I bought them, so not so many ads for me. I least I know I have a way back if needed. A BIG thanks to Vache for the file.
[Acer Iconia A500] GamezR2EZ:
Please use iconiaroot1.3 from sc2k. I have confirmed this method works myself.

The acore error is expected. Its an (intentionally) unstable ROM.

My question would be how you installed the 3.1 zip without rooting. You would have still had a locked bootloader. It should have given you the error "Boot verification failed" or something along those lines.
[Acer Iconia A500] samaliset:
I got the update.zip file from here: http://xdaforums.com/showthread.php?t=1113878 , Full Package / HoneyComb 3.1 / Acer_A500_4.010.42_EMEA_GEN3 : http://cdn.acer.futuredial.com/Acer_...1_036d89ae.zip

I did try the iconiaroot1.3 but refused to install. I think the method I am using is not the right one and as you suggest the bootloader is still locked.

I'll try again and see if I can find a way to root since it is essential for me presently.
[Acer Iconia A500] kekinash:
Can you try my steps? Don't let the tablet reboot after downloading with Vache's update.zip file, just flash again the 3.1 update file and then let it reboot. Then you can root it. Not need to boot into 3.0.1 and root it. It's just a step to reflash the unlocked bootloader.

It worked for me using the Stock US 3.1 rom
[Acer Iconia A500] GamezR2EZ:
What did the refusal to install message read?
[Acer Iconia A500] samaliset:
When I install it I get the message "a problem occured when analysing the kit "
[Acer Iconia A500] GamezR2EZ:
Try redownloading the package.

How are you installing this, with adb or on the tablet itself?
[Acer Iconia A500] samaliset:
Sorry, do you mean to download from here: 1. Download and unpack the archive provided by vache here.

I could not download it every time I try a new windo try to open the it freezes for a while after which the new window opens with plenty of caracters and get my Firefox to freeze.

I don't know what to do. Can I get this file from some where else?
[Acer Iconia A500] samaliset:
I found some thing like this : \VID_0502&PID_3325&MI_01\6&77ff523&0&0001

I added edited it like that:0X06&77ff523&0&0001 and copy/past it in the EUUS window, but I get the message: CPU ID bad format

Did I do some thing wrong? sure, but what?
[Acer Iconia A500] GamezR2EZ:
The 3.0.1 actually still flashes the locked bootloader.
[Acer Iconia A500] kekinash:
It's weir because I done all the procedure, and the use market acer recovery installer application to flash cwm, and it worked without any problem, I took it off because my tablet is encrypted and I have no use for cwm.
[Acer Iconia A500] wlk0:
You mean the Acer_A500_1.145.05_COM_GEN1 you linked a few post above ?

This is indeed quite odd, the Instruct_record.txt file mention the ROM was built 2011/08/29 (even though the build.prop is dated may 2011).

Could it be Acer is repackaging even former updates with this bootloader to avoid people using CWM/itsmagic ?
[Acer Iconia A500] GamezR2EZ:
Its 3.0.1 so of course you can. The recovery isn't locked.

The offending lines are in the updater-script. They are

package_extract_file("bootloader.blob","/tmp/bootloader.blob");

run_program("/system/bin/dd","if=/tmp/bootloader.blob","of=/dev/block/mmcblk0p4");

It flashes to the bootloader partition.

It just makes everything more.... difficult. Its only a soft bootlock though.
[Acer Iconia A500] wlk0:
Yes, I figured this, but this wasn't really my problem :)

I WANTED it to flash the bootloader, hoping it was an image from an earlier version (the one itsmagic can fool).

This would have been less destructive than using EUU's.
[Acer Iconia A500] samaliset:
A little news, I followed your recommendation by reloading and installing the 3.01 rom then rooted it and now I have the 3.2 Rom Honeyvillain working fine, except the message com.fd.updater popup. not that big issue compared to what I had.

[Acer Iconia A500] steal25:
First off thank you for the tutorial!! I keep getting the error "EUUs stop working" that happens immediately after runningPBJ20upgrade.exe as administrator. after that nothing happens. What am i doing wrong? thank you in advanced for any help with this.
[Acer Iconia A500] wlk0:
Is it still possible to use this EUU if the tablet is manually started in APX mode ?

It seems it try to use abd/USB to detect the current version, then request a reboot in APX mode, but if the tablet is fully bricked, it's likely not possible to enable USB debugging.
[Acer Iconia A500] GamezR2EZ:
Yes you can still flash all of that with only APX mode. It is quite a bit more difficult though. You still need your UID. If you have that, send sc2k a PM with the UID. If you do not have that you can get it with wireshark attached to your usb port. But like I said it will be more complicated.

[Acer Iconia A500] lechuckthepirate:
Hi... great tutorial there... I have a few questions before going on, though...

First one, is there any problem with not being an USA official ROM the one that's currently in the tab? I mean I have official OTA 3.2 but I live in spain, so I guess it's European version...

If there is no problem with the 1st question, what version will i get installed after the process? USA 3.0.1 or my zone's 3.0.1 ? Can that lead to problems with GPS/keyboard locale and stuff like that ?

Another one, can this procedure break future OTAs ?

and finally... is there risk of bricking the device? I mean, I am experienced in rooting and flashing android devices since I had my first G1, but normally all the procedures have come very straightforward... is this a risky one or it should work ok in normal circumstances ?

Cheers!!!

I am looking at "Boot verified failed.... Because I don't own a Windows device in my household, I tried to do the update.zip through stock recovery. Obviously a no go! Any idea of how to get back to 3.2 so I can start this process over again.

Finally, someone came by with a Windows machine and now I am back to 3.0.1. So once I am rooted, is there any easy path to move to 3.1 (I know that I have no love coming under 3.2) and still remain rooted? Also, granted I am going to jump back to to primee as soon as I get root going, but is there a way to make sure that I don't automatically get OTA updated, so I won't find myself suffering 3.2 again? As a last question, I was setting up CW bootloader and it asked with model "phone" was I using! The Acer Iconia is not listed, so what should I use?
[Acer Iconia A500] tresed:
if you want the 3.2 but with root, and do not receive updates, you can try the taboonay 2.1b ... works very well, important, in my opinion, is to start from a clean installation

[Acer Iconia A500] wlk0:
Now I'm lost.

GamezR2EZ mentioned this update was still flashing a locked bootloader here.

So it is working or not ?
[Acer Iconia A500] drkalo:
Well, I have not tested this method but I don't think he meant this archive in the post you linked. Actually the archive in the first post worked for many people, including people from http://acer-a500.ru/

May be GameZR2EZ needs to be more clear on his statement. I didn't understood either what he meant.
[Acer Iconia A500] wlk0:
Great, it is excellent news then :)
[Acer Iconia A500] GamezR2EZ:
The bootloader reads bootloader.blob (which is actually dd'd into the cache partition [mmcblk0p4]). It uses that to determine if the update or kernel is from acer or not. The bootloader itself never actually changes. To flash that you would need nvflash. As far as I am aware, the tegra chip protects that area from writing unless in APX mode.

My original statement was referring to the update.zip that contains 3.0.1. The one that can be flashed from the sd card with a stock 3.2 tablet, not the EUU's you have listed.

Technically Acer did release a "locked" bootloader with the tablet. They just didn't implement it very well. I thank the developers for that. Some call them stupid for doing it the way they did. I'd like to think they were smart enough to help us out by implementing a severely flawed boot sequence.

To test out what I am saying here, you can flash the stock honeycomb 3.2 rom (Acer_A500_7.006.01_COM_GEN2 for instance) with only removing the bootloader.blob and it would be "unlocked" still.

Whatever the situation, at this point Acer will not be able to stop anything because the EUU's actually implement nvflash tools which allow a completely zero'ed out nand to be reprogrammed (I have erased my chip looking for bad blocks, and recovered). So nothing they can implement through an update can stop you, don't worry.

It doesn't touch the userdata partition last I checked. It shouldn't delete your data. I have not tested that though. I always recommend a backup even if you know your data will be safe.

The first one listed WILL delete your data.

That's the same process but the Step #2 is the easiest way.

So I am trying to use the Method 2 to get a version that at least boots, but Im always getting the android exclamation mark. It doesnt want to load the 3.0.1 update from method 2. Any suggestions?
[Acer Iconia A500] GamezR2EZ:
Check a couple of things.

1. You extracted the update.zip from the main zip file.

2. Your SD card is in FAT32 format.

3. The zip is named update.zip and located on the root of your sd card.

[Acer Iconia A500] GamezR2EZ:
AFAIK Acer hasn't changed up anything and has no plans of changing anything bootloader wise. Besides, none of this really relies on the bootloader as the Transformer does.

So yes, one way or another we can root your new Iconia!

[Acer Iconia A500] GamezR2EZ:
2. Extract the update.zip from it and place it on your external SD card.

Extract the package. No renaming required.

Thats a big problem. If you cant boot into recovery, youll have to take a very long way around. Whatever issue you are having with the recovery, solve that first. There are multiple threads detailing different problems with booting into recovery, do a search for your issue.
[Acer Iconia A500] zijia3721:
After extract the package so it will be just a folder? and put the folder inside the external SD?

My situation now is that i can boot in to honeycomb. But i just cant boot into recovery when holding power down + power..it keeps stuck at 'booting recovery image'...

i googled found that using SDK might solve the problem but i just dont know how to use is..:confused:

@GamezR2EZ apologize if i have sent you multiple pm please ignore it.
[Acer Iconia A500] zijia3721:
so i have finished the process on method 1 and it show PASS on the acer logo. but it just stuck at there. so i rebooted it but it stuck at the acer logo again. What to do next?

thanks in advance!
[Acer Iconia A500] GamezR2EZ:
It shows PASS as long as it successfully uploaded the bootloader, that doesnt really signify anything, sorry.

I would try the process again, it should take about 10 minutes to upload everything. If it's any quicker, something went wrong.

Now about it not booting. Are you getting any red lettering, boot verification errors? If you aren't, that tends to point toward a corrupt boot.img/recovery.img. It that's the case, try re-downloading the EUU in step 1. But again, you should be getting some red lettering (or it should be working).
[Acer Iconia A500] zijia3721:
It just showing ACER logo when i press power button without anything else. And it just stuck at there.

it does took lesser than 10 minutes to pass the process.

but now i just stuck at the ACER logo. how do i re-do the method 1 again? It need to be boot into the system right?

Sorry for my poor english. Thanks for your reply!

Hi,

I've tried method 2 (because if I don't have to reinstall everything, that'd be a huge bonus!) - but it doesn't work...

I have the SD card (in Fat32) with the update.zip in the root. When I start the tablet (with the Volume Down key held), it reads the update.zip from the SD, goes into the screen with the Android logo with the exclamation mark, for a minute or two. Then reboots, back into 3.2.

What am I doing wrong now?
[Acer Iconia A500] GamezR2EZ:
Make sure you extract downgrade_not_stable.zip. You will have a file called update.zip

Place that on the root of your sd card. Remember extract, not rename.

Also, try a different sd card as some have issues.
