Motorola Droid users rejoice! xda-developers forum user Dan (@djrbliss) has managed to root the Motorola DROID RAZR M, Atrix HD, the Photon Q, and the upcoming RAZR HD with an exploit called MotoFail2go. The RAZR i appears to be included, although the developer notes that additional hacking might be needed, involving replacing some of the binaries with x86 versions if your attempts fail.
The entire root process looks like a one-click operation, with the exploit requiring you to press some buttons along the way. You’re going to need a Windows PC for this, the latest Morotola USB drivers along with the Motofail2go_windows.zip exploit.
As always, back up before you proceed.
