[Q] Returning Xoom Back to Stock

Can someone please outline the steps needed to update my wifi Xoom to the latest 3.1 update? Currently, my Xoom is rooted, running the Timat Kernal v. 1.1.6. I’m assuming I have to return the Xoom back to stock. I’m just wondering if someone could point me in the right direction.

Can you afford to lose data? Do you have an OTG USB Host Cable?
If you have USB OTG cable, you can download the wifi xoom (US Wifi xoom) from the link in my signature
If you don't, you still download the wifi official update zip file from link in my signature, but to follow steps here:
http://forum.xda-developers.com/showthread.php?t=1073884
(I prefer this link because you no need factor reset following this and you know what are being flashed EXACTLY.)
Then you can apply the overclock kernel (not tiamat or brd's, but TDR's oc kernel)
http://forum.xda-developers.com/showthread.php?t=1079972
Above two major steps make my US wifi xoom scream and happy. But I do acknowledge the relatively long process you need to do following the 3.1 upgrade in step 1.
If you don't care losing data and you want to go back to stock and unroot completely... go to this place to download official us xoom stock images
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
Good luck and do remember back up your data when you play with fire =)

I'm running that OC kernal now. Makes the xoom much more media friendly i.e. streaming movies and videos is a breeze.

jiwengang,
Thank you so much for replying. One last question.... If I return to stock, will I be able to re-root the Xoom, or do I have to go with a customized Kernel in order to root?

If you return to stock and apply 3.1, you will not be able to root currently unless you have a wifi only xoom

Yes you need to root at the process of flashing following the link in my reply above.
that meaning flash cmw recovery also. but kernel will be stock.
just a note that if you root your xoom, you can't rent movie from the market.

[Q] Returning to stock [i9020a]

I just wanted to make sure that I understood the process of returning my phone to stock before I make a mistake.
All I've done since I purchased the phone was root it and unlock the bootloader. I have not loaded any custom roms.
So If I understand this correctly I need to:
1) Flash the Stock Image (which should include the stock recovery?)
2) Use fastboot to lock the bootloader
The reason I'm wanting to return the phone to stock is to receive OTA updates. I never use any apps requiring root, and don't plan on loading any custom roms.
I never did find a 2.3.4 stock image for the I9020A..

you should actually be able to get ota updates no problem. it'll just remove root every time you update.
it's probably not a good idea to lock the bootloader though cause if you ever want to unlock it again in the future you'll have to wipe everything from your phone. your best bet is to just flash stock recovery so you can install the update
i'm pretty sure that works, but hopefully someone else can verify just so you don't get some bad information lol

I heard the same thing about OTA updates. If you're phone is rooted and you're using the original rom, you'll get the update but you'll have to root your phone once again.
I haven't tried this myself so I cannot verify it.
It's just the word on the street, you know!

you need stock everything, so stock kernel, rom, radio, etc... the op should be fine to update if they flash stock recovery though. rooting is simple from there

Sorry forgot to add that to post... since its unsigned you need to flash via ClockworkMod Recovery.

Thanks kibmcz ! I'm a n00b when it comes to this but when you say flash via ClockworkMod you mean get into clockwork recovery mount the usb, transfer the zip onto the SD card and then <<Install from zip>> ?
Is that the method?

Thanks again kibmcz, so I just completed the flash, then did a fastbook oem lock.
Seems to be working fine except for one thing...
When I go into settings and hit Sound I get a Force close when I try and select a new ringtone...
Should I try reflashing again?

Didn't happen on mine (In fact im using a self rooted rom based on that exact stock zip) try doing a wipe in stock recovery.

after flashing that does it take it back to out of box condition?
reason i ask is because i bought a already rooted and unlocked one here from market place and i want to return it to stock firmware, radio, kernel and such to recieve OTA updates and what not.
your info is greatly appreciated

Using my zip yes... it flashes Bootloader, Radio, Boot, System and on first boot (and any other time recovery changes) Recovery is flashed. All you got to to is lock the bootloader and that wipes user data and usb storage.

hey man i appreciate you coming forward with a solution, ive yet to recieve the phone but wanted to prepare.
my goal is to flash everything back to stock and start completly over whereas i have no clue what method was originally used to root and unlock the bootloader.
when the time comes hope you dont mind a PM if i have any extra questions.

Just did the method using the stock ROM provided by kibmcz "thanks BTW!"
Phone is back to stock, working like it did when I first bought it. Had a little trouble with some Force Close issues but did a factory reset/data clear of the cache and all that before re-flashing, and it seems to be working Vanilla!

Xoom bricked

Hi there everyone,
I have a huge problem. Last night i bricked my xoom. I was following a tutorial on this forum. and after unlocking the bootloader it told to flash a file called boot.img after doing so and typing fastboot reboot, the device wouldnt start behind the motorola logo. i tried allot of thing and also did flash some other stock android 4.0.4 boot.img files now with the last one mentioned i managed to get the xoom (wifi) to boot a little further. because the ripple movie with the motorola logo is shown. but it stucks at that movie.
Does anyone know if i can flash an image on the xoom that will atleast fix the problem of not rebooting so i can try another tutorial.
I have searched the internet for solutions, many of them linked to threads on this forum. but almost all download links in these tutorials are old and broken.
Can someone please help me unbrick my device? And maybe a link to a good working unroot tutorial for my xoom wifi with android 4.0.4.

Try get back to Stock.
Download from HERE
and do some OTA updates afterwards so everything will be up to date.
Then wipe and try again from scratch..
Worked for me perfectly just a few days ago.

If you can still get into fastboot, then its not bricked.
Get some stock images and flash them via fastboot and you'll be fine.

Indeed it worked. i downloaded the official images and flashed them im on android 3.0.1 again and all seems to work just fine now.
Next problem is i cant find a descent tutorial on this forum how to root the xoom. all download links are either removed due to copyright issues or the links are just broken.
How does it work actually?
1. I unlocked the boot loader wich is very easy.
but then? Do i need to flash a rooted image over the existing? i dont really understand how this works. I rooted my Desire HD with a good tutorial in minutes. Not many people seems to really know how to root the Xoom.
Also i would like to know if the different tutorials are for different android versions or can i aply all tutorials of rooting when i stay on android 3.0.1?
I also tried to flash a recovery.img to the recovery partition and press volume down 3 seconds after the moto logo apears but when i do i get an android robot with a big " ! " on his belly and it takes 5 minutes to load the menu. when im in it tells me there is no sdcard present when i try to flash a rooted rom (zip file).
Is there someone reading this thats willin to explain to me how to do a root the easiest way? Please if links are posted be sure everything on that thread is working. Im pretty sure i will pull it off with some push in the right direction.
Thank you!
(edit) omg im stupid, offcourse the sdcard wont work... it never worked at 3.0.1. on the xoom. can i follow this tutorial:
http://rootzwiki.com/topic/451-how-to-root-the-wifi-only-xoom-301/
Could someone read over it and see if this is a good tutorial? last time i flashed a boot.img the whole xoom got stuck... is that because i had the wrong boot.img on the wrong android version? or should boot.img always work?

Do you plan on flashing to a custom rom after rooting? If so, you can just skip rooting altogether.
I say this because I'm not particularly familiar with that rooting method you linked (though reading through it, it makes sense, all its doing is pushing the necessary files for root access to the xoom via adb). I used a rooting script flashed through a custom recovery over a year ago - unfortunately the download link seems to be broken (I might have a copy at home).
So there's a few things you can do:
1. If you just want a custom rom - download the rom zip file and store on your device. Flash TWRP (my preferred recovery) in fastboot. Boot into TWRP and flash the rom zip file.
2. If you want stock OS root access -
a) Follow those steps you linked and see what happens. If things go wrong, you should be able to just flash those stock images again.
b) Wait for me to get home and see if I have the root script. You'll need to flash a custom recovery though in order to use it.

Ok thanks for your answer. Ill try to unroot with that method flashing directly to the recovery.img i also know now what i did wrong. i flashed the recovery.img not to the recovery partition but to the boot partition LOL. thats why the xoom didnt boot anymore
I see allot about Nightlies Eos, 4.1.1. is that a good rom? Does it look like the stock version?

eos 4.1.1 is simply awesome and its also pre rooted' so your bootloader is unlocked, all you gotta do now is install twrp recovery via fastboot ( my preffered recovery) then flash eos via recovery

EOS is a pretty AOSP rom. No theme, though you can apply one if you like and change a few colors. There are various toggle additions you can add that make the user experience much better. It also comes with an overclockable kernel and is very very stable (despite being a nightly) The team has been supporting the Xoom for over a year and is very committed to the Xoom.

As for flashing, just gotta make sure your text is good before hitting the enter key. Recovery flash should look something like this:
fastboot flash recovery recovery.img

Some instructions for flashing can be found here
While that page is specifically for locking and flashing to return to stock, the commands are universal for fastboot. Hell, if you wanted to, you could manually restore a nandroid backup via fastboot and flashing images.

One way is to use fastboot to flash the latest 4.2 stock ROM. The bootloader is also upgraded in the process. Then you flash the 4.2 TWRP and whatever ROM you want from there.

I've used fastboot before, but a little more info - where can we find the 4.2 stock ROM? I followed a few links off this forum that took me to ASUS support page that stated you must select your OS (which there was no option).
Is there a thread dedicated to this?
I'm sitting on CleanROM (my Aunts), and over time, I guess this thing runs like a pig (so does my mom's stock 4.2 tablet). I am looking to make these two devices actually useful again.

OK, so with this 4.1 modded tablet, if I take the latest version of 4.2, grab the blob, and do the following:
Code:
fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 reboot
Is that going to work, or am I going to end up with a brick?
I know that there has been some warnings on upgrading to 4.1 with 4.2 files, so I want to double check before I make a bookend out of this thing.
EDIT: Pulled the trigger - worked out fine. Now I will install a recovery and we'll be good to go!

Update from 4.1 to 5.0

Hey guys, posted in a few threads but starting a separate thread to keep my issues out of them.
Anyways, my tablet is out up date and I havent kept up to speed on the last 2 years worth of developments. So im looking to upgrade my rooted and unlocked tablet on 4.1 to the 5.0 rom. My twrp version is 2.3.3.0.
How would i go about updating to a 4.4/5.0 compatible bootloader and recovery?
Ive been advised to update the bootloader, but should i flash the boot before the updated twrp or the other way around? While we're at it, I've noticed the nvflash tools. I'm assuming doing the nvflash stuff would help me recover from any possible bricks?
Any help would be appreciated.

Then unpack the zip and there will be another zip unzip it you will find a file called blob ....
Flash this blob from fastboot ...

Thanks for following me around my 3 posts, lol.
Quick questions:
1. Should I flash the bootloader BEFORE flashing the updated TWRP? Or does the new TWRP get flashed before the bootloader.
2. When I flash the new bootloader, will i still be able to run 4.1 on the tablet (i.e. is the new bootloader backwords compatible?)
3. Will the NVFLASH stuff help me in the event that I do mess something up? Seems like it supposed to be a brick-proof safety net in case something goes wrong.
thanks for the help man!

Thanks Josh, I think I know what to do now:
Step 1: Set up NVFLASH and get my backup files.
Step 2: Flash the 27.5 Bootloader using fastboot.
Step 3: Flash TWRP openrecovery-twrp-2.8.1.0-tf300t.blob
Step 4: Wipe system/cache, etc
Step 5: Flash Katkiss 5.0
Is this correct? Am i missing any steps in there?
Looks like you're not on hangouts right now, shoot me a message if we can chat. [email protected]
