Help returning my A500 to stock

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???

Thank you but that was the original method I used to downgrade and is the rom that CWm restores to from my back up.
The problem I have is upgrading via the system update.
I am currently trying to do it via a different SD card.....

there are some roms around, but you'll need a good knowledge of search button
Here's one, there are more but keep in mind they are near stock rooted roms: http://forum.xda-developers.com/showthread.php?t=1313757&highlight=stock+rom+rooted&page=1

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.

Just do this http://forum.xda-developers.com/showpost.php?p=20680452&postcount=137
It will fix your issues, guarantee it. Just read the instructions in the readme.

From what I understand, Acer Recovery flashes the US version of stock recovery??
My tablet is a UK one. I did try this before a ALMOST bricked it. I managed to recover it using a previous backup I had made.

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.

It's serious: I need help... flashing stock A501 rom

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.

Why not give HC the flick and upgrade to a custom ICS rom?

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

Nexus 10 does not boot after Update

After attempt at installing software update to Nexus 10 tablet will not boot. Have wiped Cache and even then did a factory reset. Nothing. Google appears and then twirling colorful dots and nothing. For hours just twirling dots., Samsung and Google and Best Buy geeks says nothing they can do. No longer under warranty but very upset since tablet was working great until update. I am not very tech savvy but can anyone help or do I just have a new paperweight? Thanks for any advice.
I have not made any modifications to the tablet.

Just flash the newest factory image. Get it and the instructions to flash it from here:
https://developers.google.com/android/nexus/images

yes flash the newest image

After getting a notification of the latest update I went and rebooted for the update to install but it went to the twrp recovery and nothing happens, is there a way to install the update?

as a newbie .I'm not allowed to reference your link !!
I rooted my nexus 10 using xda instructions., installed CWM. All good. I tried backup and recovery and screwed something up in recovery. Got stuck in recovery mode reboot loop. Many gyrations, no fix, so I tried factory reset. Still no fix.
I decided to install a new version of the OS using the Mantaray tar you reference above. UBS connecting and fastboot. All messages look good. Now I have the problem reported in this thread. Stuck with flying balls and no boot. Very interested in any suggestions you may have.

So you keep just boot looping into twrp, right ?
Did you try installing a custom ROM through adb or just connecting your device?
If it keeps boot looping you gotta to wipe the full storage.

No, on a normal reboot or a shutdown/restart it's fine no problems there but when I try to install the update via system update it reboots into twrp. I attach a pic of my system.

Oh I see, well, you should just flash a custom ROM or if you want to stay with official factory images, you should just follow instruction there:
https://developers.google.com/android/nexus/images
What you do need is just have fastboot executable once you are into the bootloader.
You can easily access the bootloader from twrp : shutdown > reboot into booatloader

Cool thx for your continued help :good:

The problem is due to your attempting an OTA update with a custom recovery (TWRP). You can only do OTA with stock recovery. Once you are in this situation, your easiest way out of it is to simply apply the latest factory image using "fastboot", but this will also wipe your user data so backup any photos, music, etc. before you start. You will also have to reload programs from Playstore once the new image is installed.

HELP !!! Bootloop after OTA update.

Hi, I downloaded the last update in OTA but after reboot I'm stuck on the boot animation.
I'm on the stock rom, never updated since I bought the phone in august.
I'm root and of course my bootloader is unlocked. I have TWRP that I managed to reinstall with ADB Sideload after this f***ing update get me back on stock recovery.
Now I keep trying install Roms (Official and customs) via ADB Sideload. Each time it look like the install is successful but then TWRP tell me "no os install, are you sure you want to reboot". Then I'm always stuck on the boot animation (at least it's the animation of the rom I tried to install).
Before I tried to update via OTA the 1st time I made a backup with TWRP but now all my files have been replaced by files with random letters ans numbers, so I can't even restore my backup and I'm affraid I lost everything I had on my phone.
What should I do now ?
Thanks for your help

as i said, after flashing a rom it tell me "no os installed".
by factory reset you mean format hd ? i'd like not to loose everything.

Then you have to format it and then you have to install the stock rom.
