    I updated to JB. Had root tried to keep it with Voodoo root keeper but lost it. No surprise there. Had things frozen with TB. Now I can't get root back. I probably need to do a reset either wipe cache or data via fastboot. One more twist, I live in Alaska with Verizon running piggy backed local carriers. My question is if I wipe cache or data via fastboot will I need to re-active my phone on Verizon? Thanks.

    If you just want to get root back, download and install the Razrblade utility onto your computer, then plug your phone into your USB port and follow all instructions. It will root your phone and you won't need to SBF.

    Finally got back root. I had to do a factory reset then re-ran the exploit and it worked first time out.

    Thanks for all the help.
