Now that a couple days have passed, I want to add a couple of disclaimers for anyone who may be new to this thread. Also, thanks to Synthoid at XDA forums for posting the original file which was copied from an OTA push to his Bionic.
First of all, the 5.9.902 update file below in post #10 is only for people who are currently on version 5.5.893. If you are on the leaked 5.9.901, have a look at
post #38 of this thread at DroidForums.net which has been reported to patch you up from .901 to .902 without having to go backward.
Secondly, root is not required to flash the update. However, if you are rooted, you can most likely retain root through the upgrade -- but you MUST perform the Forever Root steps in order to do so. See
this page for manual instructions or use one of the automated Forever Root methods posted throughout this forum.
Lastly, if you are new to this sort of thing, please know that flashing manual update files like this is not supported by VZW or Moto, and will likely void your warranty. You do this at your own risk, and neither VZW, Moto, or I are responsible if anything goes wrong. I will attempt to answer questions though.
Oh, and if you need instructions for flashing the file, see post #26 below.
Have fun.
