S-OFF. Those five characters represent the world to power users. They represent the ability to do whatever you want, whenever you want, without the OEM holding you down.
For many a GSM EVO 3D user, those few characters seemed unattainable. HTC had locked the HBOOT and downgrading seemed impossible. As the months passed, hope seemed lost…
Fortunately for them, a clever chap by the name of navrasis refused to give in. After much research he cracked the code, err…blocks in this case. You see with a little creativity (and a hex editor) he managed to beat the system. See for yourself here.
A word of caution though, this mod is not for the faint of heart. Any time you mess with things on such a low level, you take a chance of bricking your device.
So rejoice EVO 3D users: you won._________
