Follow my instructions CAREFULLY.
o) Install this: USB and PC Charging Drivers - Motorola Mobility, Inc. USA
o) Download this: SamuriHL_HouseOfBionic(FULL).zip - 4shared.com - online file sharing and storage - download - Samuri HL
o) Unzip it to your desktop
o) Download this: http://www.mediafire.com/download.php?46xhqt61cnmj1df
o) Unzip it to your desktop (It will ask to overwrite files if you did it right. Say YES)
o) Plug your phone in to USB.
o) Shut your phone off.
o) While holding volume up and down at the same time, press power
o) Volume down to AP Fastboot and press volume up
o) run the RUNME.bat in the SamuriHL_HouseOfBionic folder on your desktop
o) Select option d on the first menu
o) Select option 2 on the second menu
o) WAIT and touch NOTHING until it's done
Follow these directions EXACTLY and you'll be back on 905.
Leave the phone in AP Fastboot. Open SDL.exe in the rsd directory, then click the ... and go to the rsd_scripts directory, and pick the HouseOfBionic(KEEPDATA).xml script. Click start.
Yes. Leave it alone until the phone reboots. If this doesn't work, you'll have to use the FULL FXZ which will wipe the phone. I'm guessing you have corrupt data on your phone somewhere. That's not really great at all and probably why the update didn't work so well. And the OTA update probably won't fix it.
