Worked here just fine. The only thing that got me was the MYGROUP in all caps. My fault for not reading the instructions closely enough. I actually had to use it about 5 times because I was trying to flash my Bionic to cricket, screwed it up a few times and had to factory reset a few times. Funny thing was when I did the factory reset before the successful flash I'd lose root. After it was successfully flashed to Cricket I had to do a factory reset and the root held. Thanks for the easiest root ever, I think this was even easier than the old GingerBreak exploit I used on my last phone, an Optimus C.
