Same situation here. Stock ROM and Rooted and S-off. Constant nag to apply the OTA update but not working. Looking for a way to do it easy. How should I proceed? Don't want to wipe the phone and create all my settings again if possible. Can I reverse S-Off and apply OTA update somehow?

I've summarized how it worked for me somewhere on the last page of the posts.
