How to: Verizon DROID 4 98.72.18-9 or 98.72.18-8 root – latest OTA update

Good news comes to Verizon DROID 4 owner, in January 2014 a new software update has been pushed out to these QWERTY smartphone from Motorola, the OTA update come with software version 98.72.18-8 (98.72.188.XT894.Verizon.en.US) and 98.72. 18-9 (98.72.189.XT894.Verizon.en.US).

 

However, don’t expect too much in this update, since there’s no KitKat update, it’s still on Jelly Bean. But definitely, this software update will remove root access on the DROID 4. Actually, we can retain root on this smartphone by using the Voodoo root keeper before taking the OTA, many users on xda successful with this, although some also failed.

Prerequisites

        The only thing I did different from what was stated is that I downloaded MotoCast along with the USB drivers. Apart from the cleanup snafu, it went fine.

    It seemed to hang up on the “Cleaning Up” portion of the script, but ADB Shell requested SU. I allowed, went into SU, then updated the binaries. As soon as it was completed, it rebooted and completed the exploit. Thanks for the help devs! Keep me up to date on the bootloader problem and I’ll do the same.

    Is there any way to reroot my Droid 4 that has a broken USB port?

    Long story short: I was messing around with iwconfig and trying to increase my Wifi Tx power and somehow ended up getting into BusyBox and unrooting my phone accidentally in the process

    Before you ask — I charge it wirelessly with a special case and charge pad I had to order
