1. Is it true that downgrading is only working with PS3 that already had fw <3.50 installed ?
2. Are PHAT (256mb NAND) the only ones that lose bluray playback or SLIM ones are affected too ?
3. Those who already where at firmware like 3.41 and do a backup of dev_flash2 & 3, downgrade and lost bluray playback, if they restore those files are they able to have bluray again or not, cause some say yes, some say no, what's the final word ?
