Holy Cow... after days of trying various methods I finally got my Bionic rooted. with the forever root from rootwiki. Gotta love the Su status. not sure how to tell if the forever root stuck and will hold for the next OTA. The method did work on my phone with 5.5.893 (no prior root) OTB. I just can't seem to get the data from my SD card I took out from my Droid X. The apps on that SD card go back to the OG Droid days in 2009. anyway I'm happy to finally have my phone rooted again.
