Piece of cake! ...er, gingerbread
I've had my Razr a month (build date 11/2011), scoured all the forums for rooting "gotchas", and finally rooted last night.
Followed the instructions in the first post on this thread, and was done start-to-finish in under 5 minutes. Nary a hiccup! I even shot a video of the process on my Droid X. Sadly, it's not worth watching, because it couldn't focus on the Razr screen shots NOR the laptop screens, so the details of the operation are lost.
Used Titanium Pro to backup the X, and I would "like" to think I can restore to the Razr, but I suppose I'll have to download my 53 apps from the Market all over. Unless I could put the 16gb SD card from the Razr in the X and do another backup, then put the 16gb card back in the Razr to restore?
Would that be possible?
