Sorry for the REALLY late reply. As for 2.2.2, I am not sure. I have 2.2.1. If I were you, I would double check through all 13 pages of the ROM sticky. You could always use this method THEN run Basix. http://androidforums.com/indulge-all-things-root/335191-r910-r915-odin-thread-return-stock-now-r915-files.html This will return you to the original firmware the phone came with before 2.2.2 was released.
