[Q] What is required for OTA to succeed? topic

Hi. I am rooted, have installed a few root apps (Lightflow, AdAway) but made no other changes (no custom recovery, have not disabled encryption...)

I wish to take an OTA update. I understand that OTA won't succeed if I have made modifications. Is is sufficient to do a full unroute in SuperSu? Or is will the OTA still fail? Anyone have experience? Thanks!
