Can not root and Update OTA again after unroot. - Thinkpad Tablet General

When I rooted ,I backup and delete some some flexT9 input file, then I find out I can not recive SMS after root .
So I unroot ,now I get OTA update but it's says error about I miss some flexT9 file.I can not restore file without root.
Now I can never root again ,and I can not even UPDATE OTA because system fille ar change.
What can I do NOW ?

Especially if its still on warranty, send it in saying that the OTA2 failed. If enough people do it they'll release a flashable system image, I'm sure...

Issues taking OTA on ATT G2, stock recovery

So I just tried to take an OTA and it gave me an error on the install screen then rebooted. Upon restart it gave me a message saying my device was suspected of rooting and that no OTA will be taken. All I've done is root, install root Explorer and titanium and hidden a few apps. Recovery is stock so I'm on the stock ROM. I really have no use for root so I don't mind if I lose it.
Should I just uninstall superuser or do I need a factory reset before I can take an OTA?
I have AT&T G2 rooted and stock recovery. I took the OTA update and all went fine and I didn't lose root either. All good on this end other than not knowing what was in the update.
EDIT: I now know what was in the update lol! A quick google search usually answers most question

OTA and root

Just read if you are rooted, or have modified any system files, the update will fail. So if you go the ota route, go to stock first.

Hi,
I have managed to root my device (S-5360) with update.zip method. SuperUser got installed.
Now by mistake i have touched Check For Update.. and it downloaded some updates and ask me to install.
I have postponed the install.
Is it possible to delete that update file and remove the notification from my notification bar..?

Unable to install OA 6.0.1

hi,
I have a rooted moto x play (indian version)
I downloaded the OTA update, which reboots to recovery and fails. I use twrp as recovery.
And then it keeps failing. I want to install OTA update but don't want to reset my mobile.
Screenshot. ( boot loader is unlocked)
Maybe do a search prior to posting about installing an ota when rooted and running a custom recovery. There's more than a few threads regarding this specific situation.
All you're really doing is cluttering the MXP threads with non needed threads.
I'm not even going to help you out because I hate spoon feeding people who can't even or are to lazy to do either a search on XDA or google.
I did try searching for. no help
can anyone help?
Rooting means you're modifying the system. The system will not be like before. You may be able to download the update but that won't get installed. The modification of system files won't allow you to patch them with the OTA update. So the only way is to flash the firmware manually
since Lollipop, Google doesn't let the OTA install on top of a modified system. (any modification at all). If you were rooted, and you unroot, the system is still considered "modified".
you want to install an official update from your manufacturer, the recommended process is to first return your device to completely stock including replacing TWRP with a copy of the stock recovery.
If you have nandroid backup before install SuperSU, first flash that and flash stock recovery and boot into stock and get ota and flash then you can re root and flash recovery again.
