Anyone else checking this over and over like I am?
you can use the update.zip method which is around the forums [HOW TO] Install the leaked Android 4.0.4 ICS build on the Droid 4 (XT894) or use the fastboot files ICS Fastboot. both will get you to the ICS ota, the second option MAY erase all data.
You do not have to be rooted to install OTA updates...which is what all the leaks have been....OTA updates not approved by Verizon/Motorola.
Leak .217 was finally approved and is the official OTA update.
nope this does NOT require root, you take the update.zip file and follow the how-to, root is OPTIONAL, i know this as i had done this myself on a prior leak where i was not rooted.
