Cannot root A501 with factory shipped Android 3.2

Hi all! My A501 16 GB had already installed Android 3.2 when I bought it. Initially I was thinking that maybe somebody updated it before I got it but now I think the tablet was factory shipped with 3.2. I followed different guides on how to downgrade to 3.0.1 or 3.1. People are reporting that they are able to downgrade after a too quick update to 3.2 without root. But on my A501 nothing seams working. I can install rooms from A500 with Android 3.0.1 and 3.1 but after the update the tablet restarts and right after starting only a red error message "Boot verified failed …" with the ACER logo in front, I consider this a bricked. Some other rooms I can't even install, the process stops before installing on the message "Booting recovery kernel image".
I am always able to repair my A501 with the available room of Android 3.2, but without downgrade I am unable to root. I am very disappointed because one week before I bought an A501 32 GB for a friend and that one was shipped with 3.0.1 and there was no problem to root it.
Currently I am convinced that my new A501 has a different boot loader which is not allowing me to downgrade or rather start another version.
Any help would be much appreciated! Within these circumstances I could buy an I-Pad also!

No root is available for stock 3.2 far as I know.

There is more A500 than A501 Users so I think there will a root for the 3.2 version after the official upgrade of the A500.

I have the same problem with my A500.
I tried to get back from the Official 3.2 back to 3.1 as I need root also but now have "boot verified failed" and can't load any other roms on there, including the Chinese one that everybody was using to un-brick their A500s.

a501 3.2
Hi,
There is no android 3.1 for the a501, only the stock 3.0.1 and then the latest 3.2
You need to downgrade to 3.0.1, root the a501 using iconiaroot and then install any of the various 3.2 roms out there.
You need to download Acer_A501_1.309.02_COM_GEN1_SD_update.zip
Just google it and you can get it from the filesonic link.
Rename it to update.zip, stick it on a microsd card and then restart the a501 holding volume up + the power button.
This should install the stock 3.0.1 and from there, as stated above, you should be able to use iconiaroot to get root access and then reflash with any of the various 3.2 roms.
Have fun.

Thank you, your help is very apreciated. I downloaded the rom and was able to install it but I ended up as many times before with other romes. After start instantly the message appears "Boot verified failed ...". Since this is a GEN1 version I fear I need a CUS7. Any Idea where I could get 3.0.1 for CUS7? Thanks!

Ok,
Try updating to 3.2 again using Acer_A501_0.000.00_4.017.03_EMEA_CUS7 (you need to google it, i cant post links as im new).
Once you are successfully booted into HC3.2, factory reset the a501 by either going to privacy - personal data - factory reset.
Alternatively, you can try the other factory reset method where you:
1. Switch off
2. Press Vol-up + Power
3. If display goes on: Release power but hold vol-up
3. Toggle Lock switch (On>Off>On>Off)
Screen will display:
Erasing Userdata..
Erasing Cache..
Then get the Acer_A501_1.309.02_COM_GEN1_SD_update.zip file and rename it to update.zip, out it on the root of a clean microsd card and start up your a501 holding the power button + volume up to install the stock rom.
This is the process i used to downgrade when i upgraded to 3.2 and realised there was no root access and it works fine on my a501.
Let us know how it goes.

I followed your advice but with the same outcome "Boot validated failed ...".

3.2 is using a new bootloader that itsmagic doesn't work with. For now, you'll have to stick with stock 3.2 (if it's still working for you). You cannot root these devices yet and you cannot downgrade them either.

Solution
Finally the solution is here: [TUT] Revert OTA 3.2 back to 3.0.1

[Q]Won't update to Android 3.2.1 over FOTA / need original stock ROM

So first of all my tablet is brand new and not rooted and I don't want to root it.
When I got it I could update it instantly from 3.0.whateverwastheversionatthetime to android 3.2 (build 7.006.01_COM_GEN1) but it won't go from there to 3.2.1 which I hear is available for my location (France) The update tool tells me that my firmware is up to date.
I've tried a factory reset as advised by Acer customer care services but it wouldn't change. Also no matter what I do (empty cache etc.) the market won't update to Google Play Store and I think the two issues are related.
So I have two (or rather 3) questions:
1) Does anyone know a way around to force the update? (I doubt it's possible but hey "l'espoir fait vivre")
2) If not can I install a stock ROM without root and NOT compromise the warranty?
3) Where can I get such a ROM? I have searched here and here but 3.2.1 is not on the first thread and the links on the second thread are broken, plus I want to make sure that the ROM is the proper one for my region and that comes the ICS OTA update I will have no troubles doing the update.
Thanks in advance to those who will answer.

1) No you cannot force an OTA
2) It depends - others have reported returning there acer with no probs -, i think someone has even returned it rooted and been ok. These things are fairly bulletproof, and really hard to 'brick'. As long as you can read, follow a few steps you shouldnt have any probs. The worse thing you can do is try 2 or 3 different methods all at once because something isnt working right. You're best to pick one and stick with it, if you have probs ask for help in the thread you got the rom from or start your own like you have here
3) The update.zip method from the first link you posted "should" work. Did you "decrypt" the file you downloaded before extracting the update.zip??
You could try timmyDeans v4 method- it will install a stock 3.2.1, it is rooted but you can remove root using the tools he provides. Beware though this will wipe all data so backup anything essential.
The update.zip method will leave your data and settings intact
As always the choice is yours, there are some really excellent custom roms out there - I enjoy the best of both worlds with a backup of my trusty stock 3.2.1, I flash to my hearts content knowing I can always go back to it when the OTA update is out!!! Oh the joys of root priveleges

Thanks for your input, I'll make sure to try all this when I get back from work. I've a few additional questions:
1) If I install a custom rom, will the OTA work from this ROM or, comes the OTA, will I have to restore my actual Stock rom and then proceed with the OTA?
2) I haven't tried the rom on the first link I gave because it is modified and I was searching for the original, pristine, untouched stock ROM for 3.2.1
I've seen such roms around here on xda for 3.2 but none for 3.2.1, if anyone stumbles upon one please let me know.
3) Since I'm still looking for a pristine ROM before trying anything else, I have a friend whose tablet (same brand and model) safely updated to 3.2.1, is there a way to make a rom from is gear? If yes, how to?
4) (related to 3) how can I backup my actual ROM, do I have to be a root user to do so?
THX again!

1. Typically, most people do not take OTA's when running a custom rom, as basically the OTA installs a totally fresh factory Rom. This is true with the 3.2.1 update, which contains a new bootloader. Usually, this means you lose root, and Recovery, then stuck with downgrading to get these things back.
Timmy Deans root tool supposedly maintains a back door method, which s supposed to protect root, in case of an OTA. No, I haven't used this method, as I run my own 501 roms.
2. Vache has a thread "full package and updates" in the 500 Dev forum. There are several factory Roms and Updates. You'll have to look. Chances are, he may not have the specific Com Gen version you want, but probably one close enough.
3. If your friend can get adb running, you can pull a "system dump", which will dump all files/folders in the system folder. The boot.img would be nice to get, but you can probably use the current one you have. Unfortunately, he already rebooted, so you probably can't get the original full update file. If he's rooted, you can use an app called Rom Factory, to get most of what you need. It's always a good time to become familiar with ADB.
4. Well, you can back it up internally, but it's sort of useless if you can't get into your OS You will need to Root, and install a custom recovery to keep your backup externally.

ok, as Moscow has pointed out, in vaches thread not all roms are listed. My stock roms (1.016.01 and 1.139.04) for instance weren't - so I spent the last hour or two trying the "EUU gen1" listed at the bottom of the page. Well, it actually worked!! It gave me an OTA to 1.139.04 straight away. After that installed i got the 4.010.40 to 3.2 and then the next 2 for 3.2.1 - 7.006.03 and 7.014.15. So its given me the correct updates for my country AND kept my data and settings too.
SO, since you're on a Gen1 Rom this should work for you too, but still no gaurantee you will get the OTA to 3.2.1, no harm in trying though
btw timmydeans method is a gen2 rom so you can rule that out...
---------- Post added at 11:25 PM ---------- Previous post was at 11:16 PM ----------
just came across this link for an update to stock 3.2.1 build 7.014.14 here - orignal thread here but you need cwm to install it....
unless you can make it into an update.zip???
but thats way outta my league,
moscow may be able to suggest something though

Thank you very much, your answers help a lot! Just a few precisions and I'll stop being a pain in the ass!

==> @ Moscow, when you say "lose recovery" does it mean I lose the green thingy with gears when I start with volume down and power pressed/ and when I reset to factory settings?
==> @dibb_nz your method is the closest to what I'm looking for, I also hope it will give me the correct updates for my country and since Vache is a fellow countryman it might just be ok.
Anyways thanks again, I'll give a thorough look to all of your solutions and try and do a few things tomorrow afternoon. I'll keep you posted in case this thread interests anyone else.

No, what I meant to say, is when you run a rooted "custom" Rom, and use a "custom" recovery such as RA Recovery or CWM, getting an OTA update, usually wipes that out, and installs the factory bootloader. Your factory recovery....cough cough.... will still be there.
If you are only concerned about stock factory, then don't worry about it. You;re ok. Your factory/stock recovery will be just fine
The reason we root and install custom recoveries, is so we can do 3 primary things.
1. Flash a custom rom
2. Create a complete system backup to our external SD card.
3. Get rid of pre-installed useless apps.
There are other things we can do with it, but these are the primary reasons.
When you have a default factory stock system, the only protection you have, is a factory reset (hope it works), and a couple other methods which require a touch more knowledge.
Anyhow, don't worry about your factory recovery. It's just fine.

1) Just for the sake of knowledge what's the difference between GEN_1 and GEN_2? (and GEN3 and CUS7 and EMEA_TMLP)?
2) @Dibb_nz when you tried with the stock rom from Vache, was it because you encountered the same no FOTA update problem as I did? Or just to try...?
3) Something's still unclear to me after browsing through the forums: If I get an unmodified stock ROM can I flash it with the stock recovery? (so without rooting) Or do I need CWM (so root is needed)
4) What's EUU? (on Vache's thread some roms are listed as EUU)

1. The Gen's usually signify regional based roms. More specifically language support, sometimes a wifi tweak, and maybe a couple other things. Mostly though, ComGen1's are for the US and probably canada, and offer about 12 different languages. TMPL is for East Europe mostly, with polish as the default language. All roms contain the english language as far as I know.
3. You basically can't install a full rom on an unrooted tablet without CWM or RA Recovery. You will have to run the update (decrypt the file, remove the update.zip)
4. EUU is a pc based install. Plug in the USB, set your tab to APX mode and run the EUU.
If you did the root, and install a custom recovery, then you could run just about all the full roms. Your custom recovery would be overwritten, and you would lose root access. You would have a stock tablet with the version rom you selected.
You can always wait a week or so. Am sure if the update has been pushed to your country, it's just a matter of time till you get it. It's common for the update process for specific roms, to get fully done in 2-3 weeks. It took well over a week just for users in california to mostly start getting updates.

Well the official release date for the ICS FOTA in France is May 3rd, so I'll wait until then but having other options and the know-how to take actions is always a good basis. (plus I'm really not the patient type ^^)
Stupid question but I'm guessing EUU needs root too?
and also APX means rebooting while holding power and volume - right?

I tried the EUU just to see if it would keep me on my regions OTA upgrade path.
Sometimes you can have probs OTA'ing if you aren't using the rom from your region.
But in this case it gave me the correct OTA's.
APX is Acer Download mode, where the OTA upgrades are flashed - this EUU will do it via your PC. Button push method (power/reset button) not required.
No, the EUU does not need root which is why I tried it out for you
You will need to be on 3.2.1 before you will receive the ICS update
I used this EUU from vaches thread -
EUUs_SBK_Acer_A500_1.016.05_COM_GEN1
late for work will check back later

That's really helpful thanks I'm downloading the same EUU you used and will try it today or tomorrow depending on how much time I have, will keep you posted!

Ok so I did the EUU install and it worked fine, the tablet then allowed me to upgrade to 3.01 and then 3.1 then 3.2 via FOTA without any problem. But once I reached 3.2, the update tool informs me that there's no update available and my gear is up to date
So my guess is Acer France are not pushing the 3.2.1 FOTA update anymore...
Any other explanation?

Glad to hear u got thru the EUU process OK, not so great u still can't ota to 3.2.1
Others have reported similar issues not sure if/how they were ever resolved. As moscow posted earlier,ota,s are not made available to all users in all regions, all at once, so it may be just a matter of waiting for the next "push cycle" to roll round.
At least you know you can always get back to stock if you ever decide to root and go custom There no direct root method for 3.2, just use that same euu to get back to 3.1 and use iconia root and Acer recovery installer from the market and you're ready to flash your rom of choice
Pls post back if u do get the ota - best of luck
rgds Donna

Yeah I was just browsing the XDA forums, contemplating the idea to rollback and root and then installing this
I wonder if it's worth waiting for the OTA... as for what you said about waiting for the next "push cycle" I've been waiting since I got the tablet and the update hasn't come yet, which is strange because the ICS update is due on May 3rd in France and I'd guess they'd have everyone up to date and ready for the update by now!
Rooting seems pretty straightforward and much easier than what it was on my Samsung Galaxy Spica: I found this
, a file called iconiaroot.apk on the sdcard aswell, rebooting your tablet while pushing the volume down button so its starts flashing the buggy honeycomb version.
Then start up the tablet again, rush to the market, download some file manager, with that filemanager explore your sdcard, and install the iconiaroot.apk file, once thats done, rush back to the market and download and install acer recovery installer. At that point you will have CWM (clockworkmod) installed.

is that all there is to it?
In any case I'll keep you posted just so it can help anyone with the same issue!

alsoe FYI and just for the anecdote: the reason I'm so cautious about everything and scared ****less of rooting is that the tablet is a present from my girlfriend for my 30th birthday, and she'll hang me with my guts if I brick it.

Ok I rooted and flashed the above-mentioned rom and it works! I'm now under 3.2.1!
Thanks to everyone who helped me! When the ICS update comes I will post here to signal how the FOTA went.
Thanks again!

Lol, good onya for taking the plunge! Yeh acer recovery installer is brilliant, along with iconia root, makes the whole process stress free.
Will be interesting to see if you get a notification for ICS OTA with that rom.
Can always flash one of the leaks if u get impatient??
Glad everything's worked out and yr g/f still talking 2 u
rgds Donna

thx! I will post here when/if I get the OTA. and my love life is safe thanksnto iconia root

okay so the ota has been rolling for over a week and a half now and still nothing for me

[Q] How-To Downgrade Official ICS to HC

After the OTA update to ICS on my 3.2.1 Gen 2, U.S. a500 (unrooted and unaltered at the time), my accelerometer seemed to stop working. (The curious thing about this is that the accelerometer will work only if i reset with a paperclip).
Factory Resets don't seem to do anything.
I want to go back to 3.2.1 HC, and then reinstall the ICS update, how do I do this? I am currently rooted on ICS via blackthunder.

Couple options;
1. check out some of the custom Roms which may have stable working accelerometer.
2. Use blackthund3rs apxflash tool in my sig 2 go back, I not done it but I'm sure if u asked on the thread sum 1 will help out.
Our builds hc 7.014.15 have not recd an ota yet, which may bode well for thinking that Acer may be working on a patch to fix the issues in the first release. All conjecture of course

please someone correct me if i'm wrong about this.......
things you need for this to work:
timmydeans v4 zip its about 400mb (the mirrors can be slow and erratic, if you want it i can pm you a better link)
Acer Drivers from Acer Support Download Page
a pc running win7/vista ideally, xp is a bit flaky

Your cpuid which you can try getting now - the downgrade wont work without it
open terminal emulator app
and type in dmesg > /mnt/sdcard/dmesg.txt
open the text file and look for androidboot.serialno=
this is your cpuid - write it down and keep it safe!!!!
you also need to enter download or apx mode manually via button combo, this can be tricky and can become
extremely frustrating!!! It involves pressing and holding in the reset and power buttons in just the right way
....but full instructions are given.
thats pretty much it, most of the process is done via your pc -
the cpuid and getting it into download mode are the most difficult part
there are on screen instructions all the way through to help you
i've attached an image of a "cannot detect your iconia screen" which you
need to get to first before you can enter download mode....some people have had real trouble getting this to come up -
but only because they're weren't following the instructions to the letter....

You will end up with a Stock Rooted 3.2.1 gen2 with CWM

Have you tried to restore HC boot loader on an ICS rom. Don't worry just download one of the update package from the following link. As you mentioned you were on ICS rom then try ICS update only as it will update boot loader back to ics. Decrypt the file using Acer decrypter on the same link. Place the update.zip on your externel SD and then boot in recovery. Let other recovery install the update file.

Hi all,
i have the problem that the A500 does nothing else but show the Acer logo.
The only thing i can do is use TWRP.
What did i try:
I tried flashing some roms using TWRP, also some older ones but no luck.
I tried using an empty SD-card and then start with Volume - and Power but no luck
What can i do...i am stuck...

Anyone? Still have a non-working Iconia 500...boohoo
Is it an option to flash it with Clockworkmod / CWM, reboot, flash it with an Acer ROM ?

Well, telling us you've "tried some other ROMs" and have had "no luck" is pretty much telling us nothing at all.
What ROMs -exactly-?
What -exactly- do you do in TWRP?
What version of TWRP?
-Exactly- what error messages do you get?
What bootloader do you have? Sounds to me like you might have the HC bootloader when trying to install a stock ICS ROM. This is not going to work, period.
If you want help, you've got to provide enough info to help you.

Hi FloatingFatMan,
thanx for your answer.
I tried TWRP v2.1.0 with following roms:
Acer_A500_4.010.42_7.006.01_COM_GEN1
Acer_A500_7.014.14_041.203.01_COM_GEN1
cm-9-20120708-UNOFFICIAL-a500
recovery-ra-iconia-3.17-
gnm
Today i updated TWRP to v2.2.0 using openrecovery-twrp-2.2.0-picasso-signed and tried the cm-10-20120730-UNOFFICIAL-a500.zip rom. Same problem, after system reboot i only see the acer icon (permanent).
Also tried cm-9-20120708-UNOFFICIAL-a500.zip but same problem.
What can i do?

There are three main ingredients when customizing a device:
1) BOOTLOADER
2) RECOVERY
3) ROM/KERNEL
You provided answers to #2 and #3....what about #1??? What BOOTLOADER are you on?

Thanks for your reply.
I never changed my bootloader so that will be stock i think.
Finally i managed to get it going again. The trikck was to use a 3.0 stock rom. That worked.
From there i now use ICS (stock) which is fine at first. I had not seen anything but the Acer logo the past 2 weeks, so the Acer ICS will do perfectly now.
But for later on: can i use CM9 or CM10 with default bootloader + TWRP 2.2.0?

You'll need the unlocked ICS bootloader. Civato made a great guide over in the DEV section.

OK to explain for you.
ICS and JB require the ICS bootloader to run. They will not run on the HC bootloader unless specifically modified to do so. Also, no HC ROM will run on the ICS bootloader. This is why none of those ROMs were working for you.
Flashing stock ICS has updated your bootloader with the locked ICS one, so you probably won't be able to downgrade to any HC ROMs, or use any custom ROMs anymore. You can, however, use APX mode to install the unlocked ICS bootloader which will enable custom ROMs again.
I don't recommend trying to install ANY custom ROMs now until you'd flashed the unlocked bootloader. Instructions for this are in the Development section. Read VERY carefully before proceeding and if in doubt, don't proceed.

Hi FloatingFatMan,
thanks for the explanation.
I think i will stick to the stock rom at first. The APX way is not without risk...but maybe in the near future...

I am having the same "stuck on acer logo" issue. I am totally novice when talking about how to flash to ROM and stuff. Can you please direct to me a simple "dummy guide" on how to flash back to factory rom and fix my tablet. I tried the hard reset by holding down volume up and pwr button and on/off button, where i see the 'erasing..." but it still goes back to logo screen.
Please help me with my situation. Thanks in advance.

Have a look at this video
That is an example on how to do it.

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!!
