First off, hello
for those getting a black screen, it happened to me too when i tried to put this on my friend's bionic. i told him to take it to someone we know, since he knows his way around a motorola better than me (HTC loyal, sorry). He was able to get it flashed earlier. the rooted bionic was on .902. I'll be seeing him tomorrow. I'll ask him if he could post any assistance for you if you'd like.
thanks for hearing me out
i got it rooted and was using safestrap.
