[Q] MZ604 Xoom Root

Rooted my Xoom earlier today and was wondering will the OTA update (if it's ever released...) will remove root and relock the bootloader? Or are OTA updates disabled?

You will get notification for the OTA but it will fail installation. You must not be rooted for the update to work. You can however be unlocked, this will not affect the update process.

Is there any way I can unroot since there is no stock image for the european firmware?

Stock European ROM is now on MOTODEV so managed to flash that and relock the bootloader. Thanks

OTA update wont run after going back to stock from MOD

Hi am having a problem after going back to telstra stock after being on rohans JB build 3. It was really bad at connecting on LTE so I wanted to go back to stock where I have less problems. So now the 4.0.4 OTA update is available which fixes the one of the main reasons I found a ROM, that stupid settings bar.
However when I reboot to install the OTA it just boots into TWRP (v 2.2.2). I cant manually apply update from within recovery. It just gives an error. If I reboot from recovery nothing is applied.
Android v 4.0.3, software version 1.89.841.9
Do I have to get rid off TWRP or find a RUU and and apply that image? Was there some boot locking thing I need to do through abd to get the OTA to work?

Pretty sure you have to relock your bootloader and run an RUU to get your phone to true stock. Then OTA. Although, if the RUU was based off 4.0.4 you wouldn't have to OTA. You can always re-ulock your phone after an RUU as long as you have your unlock token and/or super CID.
Did you just flash a stock ROM?
Also, pretty sure there are 4.0.4 stock ROMs out there that you could flash so you wouldn't have to relock your phone.

Thanks I restored a backup I made before flashing the ROM. Might try and find another ROM to see how 4G goes.

Fixing a connectivity issue on one custom ROM is not a good reason to go stock. I think the OTA needs stock recovery, so that is why you are getting stuck at recovery. Even if it works, you lose root. Its a step backwards, so why would you want to do that?
Just flash a ROM based on 4.0.4 from Development. You can pick a custom ROM, or a stock rooted one (safe to flash from TWRP), if you want stock.
If you are rooted, don't install a OTA or run RUU (unless you are trying to fix a soft brick). Good rule for any Android device.

[Q] Problems going back to Jellybean firmware with root.

I need to go in the opposite direction many guides explaining how to downgrade the firmware to attain root. Got my tablet back from RMA with Jb .16 on it and downgraded, rooted, installed rootkeeper, flash, etc with no problems. Now I can't get back to JB. Everything I'm trying is erasing the root. I'm using stock firmware and still locked device. Should I be waiting for the device to get OTA updates back to JB? Every time I check it says no update. Are there simplified versions of the upgrade firmware that won'tt do clean installs and erase everything?
This is basically what I've been doing
-downgrade to firmware and use debugfsroot with no problems
-install rootkeeper, do a back up of root
-transfer any version of stock JB to the memory card (I've tried it with renaming the file or leaving it and letting the OS detect the upgrade)
-go back into rootkeep or SU and root is gone
There a step I'm missing? I've been at this for 5hrs now and have no problem feeling sheepish if there is a setting somewhere I need to check on.

I suspected you do a full firmware upgrade which will wipe out your root (the one you download from Asus site is full firmware version), doesn't matter if you have OTA root keeper. You need to follow the incremental upgrade using dlpkgfile method can be found here: http://forum.xda-developers.com/showthread.php?t=1803090

Wow that was fast. Thank you. I think I've hit my point for the night in trying to get it to work. I've booked marked the page and will give this a shot tomorrow.

Update OTA after root

Hi , i have my one s rooted but i have recived one update message of one update.
For this my question is , How to update after root?
I´m trying install but every time i can do it , the phone goes to teamwin recovery.
Help me.

I can tell you my experience with TMO US 2.35.531.12 minor update. First, I needed to flash stock recovery. It didn't work with a custom recovery (mine was TWRP). Then I needed to revert HBOOT state back to "relocked." Then for this particular update I was required to unroot.
Not sure if these apply to you but apparently these are pretty common processes you may need to go through for an OTA update for HTC devices, even with stock firmware. For the 2.35.531.10 update I didn't have to unroot.

Must have to relock. Im rooted. Stock recovey. Ota wont complete. Unrooted, still wont complete.

Export stock recovery.img

Hello, I would like to know if its possible to take the stock recovery.img from my current ROM which is German Stock 4.4.2 and back it up for later use.
I want to do this because i want to root my device and then return back to stock recovery. I have already tried something, btw my bootloader is unlocked.
I installed thr official german 4.3, sideloaded the official german 4.4.2 and used cwm and rooted but then i looked in both zips of the stock roms and there was recovery.img only in thr 4.3 one so after rooting i flashed recovery.img which screwed everything, because another small official ota update, only 1.9mb which was already on 4.4.2 with 4.3 recovery and the phone booted normally and wanted to update that small ota update and after 1 min the phone restarted but it wouldnt go to the recovery and install the update it wpuld reboot over and over again
My question is how can i back up the stock 4.4.2 recovery.img for later use, thanks in advance for amy helpful posts

Hi,
I think the easiest way would be to check your ROM version and download the complete firmware from somewhere like FileFactory and that package should include the stock recovery which can be easily flashed back after you are done with the root.
