Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port. It sets new standards for speed, flexibility, and simplicity. And it’s on MacBook Air, MacBook Pro, iMac, and Mac mini.
HTC Thunderbolt is one of the toughest device to root. The XDA developers team member dbzfanatic has developed a utility Easyroot + S-Off that makes Thunderbolt root process very easy. This will only work with firmware versions lower than version 1.12.605.9.
