Hi,
atm, I have an A501 with CWM-based Recovery v5.5.0.x(thor2002ro rev1.7) and Android 3.2 (EMEA CUS7 - Germany).
My Tab tells me that there is an update, which I downloaded and tried to install. However, after a few seconds an Android with a red exclamation mark appears and the installation of the updates aborts.
So, I want to remove CWM Recovery and root and return to a stock rom. However, that seems impossible. I downloaded the Acer Recovery Installer App but this one offers me a USA A500 stock rom - but I need an A501 rom because of 3g.
When I try to install this one (http://forum.xda-developers.com/showthread.php?t=1234039) I decrypted before, CWM tells me
"Installating update...
Installation aborted"
So, this does not work either.
I am really desperate because I have to revert to a stock rom...
Can someone please, please, please help me out?

The update has overwritten yr custom recovery with the Acer stock recovery. It also checks yr system files if it ain't completely stock it will abort. being rooted can also affect the update.

Thank you a lot for your answer!
Yes, I did install cwm again from acer recovery installer, but that did not change anything.
Unfortunately none of the roms offered on xda work, they all abort in cwm and I don't know why.
I would prefer to go back to a stock rom with stock recovery because I want to give the tab to someone else.

Yeah, you may have difficulties flashing full packages via CWM. Especially if you didn't decrypt the rom first.
I've got a few 501 roms you can try. All HC 3.2.
One of them, is an ATT full package update which will probably work for you. Just pull the update.zip out of it. Put it on your Ext SD card, and boot holding PWR and Vol+. This will force it to install update.zip from the SD card.
Any rom you use, you have to decrypt it first. Some try renaming the rom to update.zip, and some have success using this method.
Like I say, it's an AT&T rom, but is probably really a ComGen 1. So it should have decent language support.
If you're interested, I can throw them up on a server tomorrow.
But I tell you this first, before you go messing around with these things. GET YOUR UID Number first, and write it down. You can get instructions on UID in the Development Forum, 1st page usually. It's easy.

No probs!!
U must use a "update.zip" , decrypted first as Moscow said, and booting into recovery via button combo may help too,
also remember to remove the zip file off the ext. sdcard when you are done!!
....good luck

Hi
I'm going to update my a500 to 3.1
I have unrootedmy device but how to remove CWM completly????
Please help
Why don't just update via CWM:
http://forum.xda-developers.com/showthread.php?t=1154492
1) re root your device
2) go into acer recovery installer and reflash to the backed up recovery (or do the stock recovery for your version)
3) de root.
I had to do this to get my update to work.
Do you know where can I find stock recovery for my version?
I have Acer_A500_1.139.05_COM_GEN1
thank you!

When i installed ARI, it backed up my current recovery. When i went back into ARI, my old recovery was the first option. Sorry, explanation sucks, i don't have screenshots for you. I know there are threads with most of the software/firmware elements of most of the different versions, maybe do some digging? This would be the best place to start: http://forum.xda-developers.com/showthread.php?t=1126364
Look in system/etc for a filed called install-recovery.sh. if its there change its permission from 444 to 544. Then reboot normally. It'll overwrite cwm with your stock recovery.

Hi Euclid, are you able to post a copy of that install-recovery.sh file? I don't seem to have it in my system/bin anymore
...That is assuming the file is not unique to each device??
I'm thinking the reason my OTA update wouldnt install is because i dont have the stock recovery menu.
Thanks!
I really don't get why everyone is spazzing over this... If you've already taken the steps to root and install CWM in the first place, why not just install the stock 3.1 image that's been provided in the dev section? It's 100% stock, no need to wait for Acer to stop twiddling their dangly bits...
Floatingfatman, that is exactly what I did, and it worked perfectly. Good advise!

Yeah thats what i ended up doing to update it to 3.1.
Reason i want it back to stock is that i couldnt update via OTA at all (downloads fine but install fails at ~20% with the ! in a red triangle).
I was hoping by restoring it to stock the OTA would work, and so any future updates could also be done via OTA as opposed to finding a workaround each time.
Other than that, it's working just fine for now.

Never mind. Problem solved.
I need some help unrooting and returning to stock. I rooted the device using the method of returning back to 3.1 and flashing the unstable rom then installing iconia root then acer recovery to install CWM. After rooting I did not make a backup of my device so I have lost the original rom. This is an Acer Iconia A500 with 8gb internal storage bought from Best Buy on black friday. I've read through many forums in the development area but since I have not posted enough times I can not ask a question there. Any help would be greatly appreciated.

Basically, when you run a full package stock rom, it should put your tablet back into stock condition. This will remove the custom recovery, just like it did when you downgraded.
You can find a list of the stock roms based on region at this link.
http://forum.xda-developers.com/showthread.php?t=1113878
Vache put some instructions there, and it's pretty simple.
Sorry, I'm new, and have the same question.
I am confused, for clarification ....
If you are unrooting and have Clock Work Mod Recovery what do you have to do?
I used Acer Recovery Installer from the market to install clock work mod. If I am unrooting and returning to sock, should I use the option to install "Stock USA 1.41.07_COM_GEN1 recovery" before flashing and then use the power/up button combination? Is it Ok to use Clock Work Mod to install one of the stock roms from the SD card or will Clock Work Mod cause a mess?

Vache has simple instructions on that page. As you read, it says to extract the update.zip file, put it to sd, then hold vol- and pwr. It should flash the rom, That's for the update zip..
However, I would use one of the full set roms.
When the stock rom runs, it should overwrite the CWM recovery, and re-instate the factory bootloader.
Here are the instructions direct from Vache's page for full rom.
"Here are some full packages, updates and EUU firmware from Acer OTA server and from some magical sources.
Full package and updates should be flash via the recovery.
EUU version are working in APX mode with nvflash. (you can enter in APX mode by booting the tablet with Reset / Power pressed)"
Now, what other recovery do you have to flash a full rom?
NOTE: I have not and have no plans to revert to stock. So I've never done this. You may want to post a question also in that thread to see if you can get any extra info.

You could also use the Downgrade tool with the original downgrade images. The original downgrade tool will put back factory recovery and factory stock. This would be everything you need to be totally stock. Once you get to stock, then you can just apply the OTA's if that's what you want. Or are you trying to get to stock and then root?

Yeah, I keep forgetting about your tool.
I think they just want to get back to a stock condition without cwm and root.
You may want to post a link to the tool.
Finally got it. Used the Acer recovery tool to flash Acer stock recovery image and then extracted the update zip from the full package and put it on my SD card (made sure it was the only zip on the card) then redooted into recovery by holding down the volume up key and the power button. Update flashed and all is back to stock. Reasons for doing this were that I could not find a ROM that seemed like it was a real improvement over stock. My favorite would have been Thor's ROM mostly due to the ice cream sandwich tweaks and the ability to clear the recent apps drawer. May go back to root but wanted to know how to get back if necessary. Thanks for all the help.

Glad it worked for you!
Vache should be a touch more clear on "which" recovery to use for the full package
Although it seems people used both CWM and Acer Recovery. (he just states "recovery")
Glad you cleared that up

@sydeu, you probably want to run Acer_A501_4.037.01_EMEA_TMPL. Note this is for the 501 so not sure if you are looking for a 501 or 500 stock rom.
I run it on my 501, and it has svetski lauguage support.
I think you can use any of the EMEA roms. You can unpack or decrypt the roms before flashing, and check the ldb files (system\usr\xt9\databases\ldb\) You should see an ldb that usually starts or contains "Sv". I think these are related to the keyboard, but it will have system support for the language.
Not all roms and updates are listed there, those are just the ones people were able to find. So get the one that's closest to your needs.
I downgraded my unrooted A500 on 3.2 to the "unstable" 3.0.1
I then rooted it and installed CWM.
Then I made a back up on CWM before flashing another rom.
It worked really well except a couple of bugs (No audio on HDMI and reduced battery life)
I know beggars can't be choosers but I would prefer if EVERYTHING worked.
So....I restored my A500 from the backup of 3.0.1 via CWM with a hope to just returning it back to factory settings and returning to an unrooted 3.2
However, when it tries to do the system update it fails.
I have tried the factory reset and then tried again to update via system update but still fails (I get the blue honeycomb bee with exclamation mark)
Can anyone point me in the direction of a stock 3.2 rom that I can flash via CWM?
or even better, one that means I wont lose root???

This happened to me.
You need to install Acer Recovery from Market and flash the Stock recovery before it will let you update with system updates.
Here is a link to stock rom using cwm but it says its not rooted:
http://forum.xda-developers.com/showthread.php?t=1429199
Since this looks like it keeps cwm in place you should be able to download the flashable version of super user and root your device through recovery.

I tested this out with both the transformer and slider. No need to do anything complicated.
ASSUMPTION:
You have CWM installed.
INSTRUCTION:
(1) Download the latest firmware from asus website.http://support.asus.com/download.aspx?SLanguage=en&p=20&s=16&m=Eee%20Pad%20Transformer%20TF101&os=32
(2) Unzip it. Inside, you should find another zip file. Place that zip file on your micro sdcard.
(3) Plug in your micro sdcard. Go into CWM.
(4) Wipe data/ factory reset, wipe cache partition, wipe davik cache.
(5) Flash in the zip file you just got from the asus website.
(6) Once restarted, you will be back on non-rooted stock rom and stock recovery.

With CWM recovery you can flash ROMs.

Download and install this app. Run the app and grant superuser access. Then flash the custom recovery. This will install cwm recovery. Then go to the development section and browse the custom roms. Download the rom of your choice, place on sd card, boot into recovery (shut down, then hold the volume down key and power key, then when prompted on screen, press the volume up key) Before flashing a new rom, u will want to do a full wipe first. (back up any needed data first) You will want to install from zip file. Choose the rom you downloaded, and now you have a custom rom installed.

This worked perfectly and it fixed my USB issue from flashing the repacked ICS update. I love that Asus made the App Backup tool so I could just restore all my apps without Titanium!! So awesome!! Thanks again!
This isn't working for me? when i install the .zip from the asus website it says its completed installation but when i boot the tablet back up nothing has cahnged and CWM remains ??? is it because i have a tf101g?

Will this work if I flash the German over rooted ww-version?

THIS IS FROM EAZYTERRYS
The real answer is if you have ICS, to install a custom recover or custom kernel you must have an unlocked bootloader.
The following resources are related to the new bootloader, a quick read of the OPs of the first two are highly recommended, even if you install with the third link. (This is to have a highlevel idea of what you are changing on your device, as it will help you find what you need to look closer at in future if something goes wrong, or possibly prevent a problem in the first case) bootloader thread civato's guide Afterota tool (windows users bootloader install tool)
If you already have the unlocked bootloader installed, but can't boot into recovery:
This is likely because you have a stock ICS rom overwritting recovery with the stock recovery in every boot; either use fastboot or (if you have root) a program such as acer recovery installer to force the install of a recovery and immediately reboot into it. (Most bootloader installers will also install a recovery that you can immediately boot into)
Once in recovery you can backup/restore/or install a rom modified to prevent the overwrite of recovery. (More advanced users can stop this from adb by removing some files)
Personally I use a lightly modified version of the stock rom you are using now: http://forum.xda-developers.com/show....php?t=1661492
it ought to be safe to do a no wipe update to that and receive a more expected environment with a custom recovery, optional custom OC kernel, and busybox support.
However if you explore the dev section, many other (both more and less modified) versions of ICS roms exist. Themed and otherwise. So feel free to explore.
