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.

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???

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 did the trick!
Thanks for the heads up
Will this work?
Currently on HC boot loader and flexreaper ics.
1. Use Acer recovery to load stock HC 3.1
2. Use Acer recovery to load stock recovery.
3. Ota update to ice or flash update.zip
i choose full system restore since i backed up the stock system in CWM before flash custom rom. after a full system restore i simply open up the acer recovery app and choose to flash back stock acer recovery then unroot.
Oh yeah, forgot I had cwm backup of rooted 3.2. Will that work?
if it's your original stock system, it would definitely work. there is nothing better to OTA to ICS with with your original stock system. but you definitely needed to get into acer recovery installer to flash back to acer stock recovery. some said there is no need to unroot and it would OTA fine but i unroot it any way. better to be safe.
I had already done 3.2 ota before rooting using timmydeans method.
Bummer. MD5 mismatch on my first nandroid
At this point with a corrupted back up, i think your only option would be to go back to square one and try out stock rom to see if they would let you update.
if you are familiar with APX mode and nvflash. you could download the EUU from vache to get back to HC 3.01. See if acer would let you update at 3.01, if no then you could try to flash Acer_A500_7.006.01_COM_GEN2(US) or the Acer_A500_7.006.03_COM_GEN1(other country) stock rom via the good old method of update.zip. first link is vache thread with acer stock rom. second link is the guide to flash euu and wipe all the data (so back up all stuff and download the EUUs_SBK_Acer_A500_1.016.05_COM_GEN1 from vache's thread and follow the guide on second link. Don't forget to replace the UID with your own UID after extract the EUU file. if you have no idea what i am talking about, i would say DON'T DO the EUU.

Hi cris8599, for what you said, I think you already update your tab with OTA, it's that right?
Can you tell me how do you unroot your iconia? did you had any problem while updating?

yes, been updated to OTA ICS since April 28th to rom Acer_AV041_A500_1.033.00_PA_CUS1. 3.01's unroot is easy simply click GingerBreak and choose unroot. i am not sure if 3.1's iconiaroot-1.3 is easy as gingerbreak.

From yr tabs ext.sd card with stock update.zip from vaches thread or buggy Chinese rom
An EUU via PC from same thread
Timmydeans v4, EUU based hc 3.2.1 gen2, full stock, rooted, cwm
The EUU can be used on either boot loader, not sure if same goes for update.zip
I had thor v14.2 and thor touch recovery 1.7 on my a500. Read whole bunch of threads regarding return to stock, unlocked bootloader, and corrupted recovery stuff but couldn't find the exact steps of how to upgrade to stock ICS.
Anyway, here is what worked for me:
1) on thor v14.2, download/install acer recovery installer
2) install stock recovery
3) factory reset (I didn't care about backups)
4) download HC 3.2 (Acer_A500_7.006.01_COM_GEN2) from -
http://forum.xda-developers.com/showthread.php?t=1113878
5) copy update.zip to microSD
6) vol- + power to enter recovery and flash update.zip
7) now a500 is back to stock
8) OTA update multiple times from 3.2 to 3.2.1
9) install Acer Update Enhancement
10) OTA update to 4.0.3 US version (Acer_AV041_A500_1.033.00_PA_CUS1)
After getting ICS US version, I found that only four languages are supported now. So I downloaded EU version (Acer_AV041_A500_1.031.00_WW_GEN1) from -
http://vache-android.com/v1/index.php?site=files&file=151
and flash it over. Now I have my language on a500 and it runs pretty smoothly.
I used acer recovery to install stock 3.1 HC Rom with Root. Installed stock recovery, then applied update.zip to get to ICS 4.0.3

Wrong thread....disregard
I want to root my N7 directly from Linux, but I don't want to replace recovery with CWM. I like CWM on my phone, but I understand it won't allow OTA stock upgrades which I expect will be important for a while on the N7.
I've already unlocked the bootloader, but I haven't seen any instructions for rooting from Linux without replacing the standard recovery with CWM.
Can't you just flash CWM, root, and then reflash stock recovery?

There won't be any OTA that is not quickly (if not before it is released) will be available is a flashable download on XDA and other forums.
You are not going to miss anything.
You can as already posted, reflash the stock recovery, but again, whats the point.

Where would I find the stock recovery?
Hi,
I have a rooted Nexus 4 with android 5.0 lollipop build LRX21T.
I have TWRP recovery installed version : v2.8.0.1
The device id rooted via placing the zip file in the device and flashng it via TWRP recovery.
But i am not able to update to android 5.0.1 via google OTA update.
Everytime i try to install the 5.0.1 OTA it goes to TWRP recovery.
I found that the downloaded OTA update file is placed in /cache folder , so i try to update it manually but failed as it shows some update partition error.
"E: error executing updater binary in zip '/cache/e93b********************.signed-occam-LRX22c-from-LRX21T.e93b****.zip"
update partition details.....
I think i am getting this error because the device is rooted.
Can someone guide me how to update my device..and if this because of the rooted device how to unroot without going back to stock.
Thanks in advance....
You can't flash the ota in twrp. You have to be 100% stock recovery, system, kernel, and radio. Flash the stock recovery with fastboot then try the ota.
Sent from my Nexus 9 using XDA Free mobile app
I flashed the stock recovery the OTA update continued in the stock recovery , then it showed a error....and i had to restart the phone ...now the ota update has disappeared with the phone still in android 5.0 ...Can you tell me how to get the OTA update back...?
1)Does the error came because the phone is still rooted ?
2) If so how do i remove the root with returning stock .?
3) also if i root and return to stock will it wipe my phone apps and their data...
Now i got the OTA update downloaded manually on my laptop and and booted into stock recovery to try to sideload the zip it gave me the error
"package expects build fingerprint of google /occam/mako:5.0/LRX21T or google /occam/mako:5.0/LRX22C user release keys; this device has google/occam/mako:4.4/KRT160 user release keys .....
This is weird as i am running android android lollipop 5.0 LRX21T and not android kitkat....

Try flashing factory image.
The OTA will flash only on the stock recovery it won't work in any modified/custom recovery. So flash stock recovery first then you are good to go.
Edit: You may also try flashing the factory image, u may lose your data while doing that
Head to https://developers.google.com/android/nexus/images and download the latest image, flashing procedure is explained there too.Its not compulsory to lock bootloader afterwards BTW, its personal preference.

Actually i dont want to flash stock as i will lose all the data in the process....
Any other way....?
If there is no other way could you please suggest any tool kit which will backup all data including sms ,contact, call logs and all app data and /data/media folder. in one go ...?
use advanced backup from twrp backup menu and select data only to create a nandroid backup of data only
you can also use titanium backup to backup to choose what to backup and restore it afterwards but it will need root again.
sync your contacts with google server
Flah rom in fastboot
Download factory image, flash system, bootloader and recovery manually. You won't lose your data.
You need stock recovery to proceed flashing the OTA, custom recovery won't flash the OTA, i don't think being rooted is the issue Just flash the stock recovery to solve the problem.

Rooted IS an issue. You can't be rooted and apply the OTA file, it will fail every time. As a previous poster has said, the phone MUST have stock bootloader, recovery and be not rooted for the stock OTA's to apply. If they see any modification during the process, they abort. It's been discussed many times.
