look at my story:
PS3 Phat Console
Downgraded Using E3 Flasher
To Rogero CFW (This FW doesn't get games work (Black screen issue) and not compatible with some pkg.)
then went to TB CFW (This FW can only load some games and some games doesn't work.)
i let this about 8-9 hours to copying game 7Gb through filezilla. and i went to sleep.
in the morning i have check this also not work black screen issue.
i went to Kmeaw CFW after installation complete the ps3 restart and become bricked with YLOD. that's all.
