        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
