We have been working on this for a few days in the dev forum, and we've always run into the same issue: makeself fails to properly rebuild the modified elf into a proper self.

I'd like to compare your self with our attempts.
Working hard on UberCFW, incorporating NTFS, sub-free NetFlix and Blockbuster, PSN cheat system with built-in swearbot and MAC-spoofing, Adding MKV, RAM and BIK movie support, and Xbox360 emu*.
