i have this assert failed with the userdata as well.
i've wiped data / cache and rebooted. reran Option 1. still getting the userdata Assert Failed error.
This is where I had to use Option 2, then reboot, you will see a green guy with a loader, screen goes black, dont pannic, hold vol -+ and power, screen will flash turn on and boot into recovery, reset/data Note: I didn't lose anything, don't reboot yet, do the update.zip and wait 10 min and when (its) done, reboot and finished, all my stuff was found, its working good. If anyone has 4g issues, apply "motorola patch Restore Connectivity Settings - Motorola droid Razr"
