I was on 896 w/ KIN3TX. Then I followed these instructions to get to 902 (I know about the malware warning. It wasn't there when I did it) [Download] DROID BIONIC Fastboot Files (5.9.902), with flashing instructions. I'm sure if you searched hard enough you could find an image to go from 896 to 902 without using the link above, but I used it and had no problems.
THen: .902 Root Method (complete) + Safestrap. Features Th3ory Axi0m ROM
After that I installed axi0m and played around with Eclipse too.
Then today I did this 5.9.904 Update for Droid Bionic Leaked! - BIONIC - droidHIVE Forums
THis again: .902 Root Method (complete) + Safestrap. Features Th3ory Axi0m ROM
and also installed KIN3TX 901
If you having issues booting up I suggest doing a full wipe and also in Recovery go to "Format /system" and then install the ZIP again
