Hello everyone! So as in an earlier post i had a list of questions regarding the PS3 Jailbroken etc etc. So i purchased a Jailbroken ps3 with Cobra CFW on it and is at 4.46 CFW and I kind of want rebug instead with a higher CFW. The problem is I have no idea if the system is CEX or DEX and how can I update from COBRA CFW to REBUG CFW without bricking my unit? How do i find out if i have CEX or DEX. Where can i find a decent tutorail on installing a PS2 classics PKG successfully to play PS2 ISOS. Any help you folks can give is greatly appreciated.
