Recently my ps3 has stopped playing discs I tried updating it and at 99 percent it gives the error. I've tried a new ribbon cable and putting the daughter board in different drives but nothings working. I'm not sure if the problem is on the daughterboard or the motherboard . Before I tried updating it the drive would accept and spin discs but the game wouldn't launch on the XMB and just keep spinning the disc until I ejected it.
