Question [Q] Failing OTA update after unroot(.108)

Hello!
My phone can't seem to accept the OTA file, even after I've unrooted it. I don't have custom recovery and I have a locked bootloader.
The error message is "The file could not be verified" which I supposed was because of the root, apparently not.

Anyone know what's up? It's the standard C6833.

It`s because Rooting changes sone Files. Just back up your Data and use the Update Centre for reflashing

Alright I understand, I thought a unroot and removal of supersu would suffice.

Update center, that's the Sony PC companion yes? Won't I loose all my data?
Even with a backup, don't I have to set up the whole phone again? As if I would flash a ftf?

yes whith this method you loose the Data, but you can also try to flash an FTF, which should have the same effect. You just have to set some Files to the state bevore rooting or wait till you get the Update via PC Companion or update Service. I think the best way for you is to wait till PC Companion shows you the update.
