Hello, i have a jb ps3 (CECHA12), that has a non-working bluray drive. it is currently on rogero cfw 4.40 ver1.03. it plays games without any issues, be internal or external hds.
recently, i was able to acquire another ps3 with the same model (CECHA12), it has ylod, but has a working bluray drive.
i tried to swap the bluray drives since i thought they were the same model anyways, now all of my games on my working ps3 is not booting properly, even multiman.
it just goes in black screen. i thought the cause was the bluray drive so i switched back the non-working bluray drive, but it is still the same - boots up properly, but upon launching of games or multiman - no display, just black screen. and it does not recognize the working bluray drive btw.
i read somewhere that i should downgrade from 4.40 to 3.55 in order to re-marry the bluray drive. i read about the method, but on one part, it says i should enter factory service mode, and for that i need a flasher - which unfortunately i don't have.
any help would be appreciated, please point me to whatever files do i need to download and install to fix this issue. thanks!
