well, this is cool. i'll stick with 3.55 for a bit until a confirmed (near) flawless release comes out that has less than 1% brick. i think i might just try to use the keys to patch newer games for the time being
Seems like Rogero will soon be releasing a brick-free version with bug fixes.
Today he said: Please anyone with a hardware flasher and a machine that bricked while installing the CFW then you have un-bricked it, please contact me.
Because what I need to fix this weird problem is someone who already have a flasher, a PS3 that bricked, so we can fix it, then replicate the brick, then re-fix it, and test another version of the CFW4.21...
