OK. Did a forum search and a Google search. I understand what Kies is but is it really necessary? Can connect via MTP now so no issue there. Did notice that latest firmware update fails (twice now) without kies. Will either kies or the update break root? (am doubting but am curious!)
thx
Kies is just syncing software and applying an update will remove root. All you have to do is reflash the root.zip file in recovery and then update the su binary using the superuser app and you are rooted again. Kies isn't necessary you could update manually, that is if you can find the update file somewhere to download to your sdcard, then run it as an update through recovery.

back at 4.0.3 on my galaxy tab 2 10.1 i rooted it via odin. when i updated it yo 4.0.4 i didn't have root access anymore but Superuser or superSU was still installed. whenever i opened it and tried to uninstall it, it wouldn't do anything so when the jelly bean update came out it i updated it and Superuser/superSU was still there. i have tried factory reset and still wouldnt work, when i check the update button it says your device has been modified software. updates are not available. (check this thread if i left out any info http://forum.xda-developers.com/showthread.php?t=2101392) then i saw that we have CF autoroot. i flash it Via odin and the first time it didnt do anything. it removed the Superuser or SuperSU app but looks like im not rooted. i have checked some root checker and all of them wont respond they keep saying checking for root only one root checker said i had root but was really fast and didnt look like it was a legit root checker. should i flash CF auto root for a second time?
If i were you, i'd probably start fresh. Factory reset - go in to download mode and flash a stock rom of your choice through Odin. (do a backup, just in case)
i tried to install update 68, the shield reboots get me to the screen with the android on its back, select the update install, then it errors out?
is the device being rooted causing the issue o the bootloader.
also if this or any small update installed correctly would i lose my root access,
if i lose root, will i always have to start from a factory rest and lose all my information to root it again.
thanks
An unlocked bootloader is not the problem. If you somehow modified the system image ( like rooted/removed apps, integrated updates into ROM, installed custom recovery or something else) the update process will fail because of it. That might have to do with the fact its an incremental update which checks if it is modified/rooted and/or will update apps which aren´t there anymore.
One way to solve this is to backup your apps and data. Then flash stock recovery and stock image via fastboot and install all updates from the beginning.
The other way is to go to Nvidias Support Page for the Shield. Then download the latest Update for it. It´s an sh package which needs to be extracted under Ubuntu or special tool for windows. Then you can flash the newest image and recovery directly with fastboot. Didn´t try that.
Hope i was able to help you.
Hey. I was wondering if you could help me update my phone to the latest ota update. I'm rooted and have xposed installed, and anytime I try to update the zip fails to install. I've also tried removing xposed, but it still didn't work.
Any suggestions?

Use search, you can't use OTA on a rooted phone as rooting alters system files that the OTA expects to NOT be altered.

In another thread they told me that I can update if my phone is rooted and with stock recovery.
What you can do is flash a custom recovery and then after copy the outs file from /cache to your PC. On your PC modify the updater-script and repack the zip file and flash it on your phone through custom recovery.
You can even unpack the contents of OTA. zip and manually copy it in your /system and fix the permissions.
So I unrooted my Shield Tablet a while back without changing the stock recovery, and found out that whenever I try to install an OTA update it shows an error during instalation, rendering me unable to aquire the 2.2 and 2.2.1 updates. Already tried unrooting it, locking back the bootloader and so on. I can still sideload updates to the tablet but would like to gain back the convenience of OTA updates. Has anyone encountered similar issues? Could anyone help me fix this issue?
Saw the probable solution on another post.

In these forums somewhere I read that the unroot was done using Super su's full unroot option. However it apparently left behind a few files that caused the OTA to fail. So what he did was to uninstall Supersu, reinstall Supersu and update the binary. Then use full unroot function... Maybe it will work for you if you have unrooted using SUpersu...
Unrooting, locking the bootloader, and flashing the stock recovery doesn't allow you to take OTA's.
There is THIS thread, providing OTA files that can be flashed in TWRP or CWM. And are official files from Nvidia.
You have to flash these every time there's an OTA, or just flash a full stock image through fastboot, and never root or flash a recovery.
I'm having similar issues. I was rooted with CMW recovery but unable to install OTA update. I unrooted, and did a factory reset of the OS.
I tried to install stock recovery 2.2.1 (found on another thread here) with adb sideload command with the following result:
"cannot read "update.zip" (I tried the original filename and changed it to update.zip. Neither worked.) To test adb, I installed Supersu via the same method.
Trying to install the OTA update I receive the following:
Invalid command argument
Finding update package...
E: unknown volume for path [@/cache/recovery/block.map]
E: Can't mount @/cache/recovery/block.map
Installation aborted
I do apologize if I've missed something. Some of the other threads I've been using to learn are many pages long. Any help is appreciated.

It depends on whether you're using SuperSU or Magisk.
To unroot if you have SuperSU, open SuperSU app, then open its app settings, find the setting that says something like "cleanup for unroot and uninstall". That will remove the su binaries and uninstall the SuperSU app.
To unroot if you have Magisk, use the Magisk uninstaller.zip(might cause bootloop which then requires flashing stock firmware via Odin)
Or you can just flash the stock firmware via Odin to remove root. You're going to have to get rid of TWRP also which would require you to flash a copy of stock recovery to replace TWRP. Flashing stock firmware via Odin will replace TWRP and remove root all in one shot, no need for extra steps or tricks.
Then you can do the OTA update.
OR
An even better option is as follows.
The OTA update might even be available to the public to download, if so, you can download the update manually(not via OTA) then flash the update via Odin, this will replace TWRP, remove root and update the device all in one shot. This way, you won't have to do anything except flash the update and you're done. No need to replace TWRP and unroot before doing the OTA update. This method skips all of that and gets you the update without having to do all the extra work. You'll have to root the device again and flash TWRP after the update has been applied.
If you choose to do the OTA instead, make sure you are completely unrooted and are back on stock recovery, you can't have root or TWRP when you do the OTA, it will not work that way.

Is the things still the same... namely unrooting will not return KNOX and can not use Samsung warranty?
