After much google searching I found this page:
. I hope posting it here is OK. This is my 1st post in the forum. Anyway, after flashing with TWRP, I found that everything was working. You have to reinstall all your apps (at least I did) so backup your apps first. I did a total backup to SD before flashing. Myself; I was hoping for a more stock 4.3 experience. CM 10.2 was impressive though, just not what I was hoping for.
HOPE THIS WORKS FOR YOU! KEEP POSTING YOUR RESULTS!
Device, Razr M XT907 4.1.2 updated stock, rooted running TWRP recovery.
