I just tried OTA update and it said it "could not verify" - after some research seems I have to remove root. But I dont want to have to wipe my phones data.
Is there a way to remove root without wiping data? In superSU, there is a "Full Unroot" option but will this actually remove root so I can update?
OTA update generally removes root. But you should be able to root again with the same procedure. The full unroot option in SuperSU does actually what it says and will fully unroot your device allowing you to update the firmware.
Just give it a try.
