Ok, it will be quite a long story, but I will appreciate it if someone can help.
Basically, a friend has a 60 GB PS3 that wasn't used for a long time (was on firmware 2.xx). Last time we played it, it worked fine (months ago). Today he brought the PS3 so I can install it a CFW. I upgraded the firmware to 3.55 then to 3.55 Kemeaw. We decided to check out if it worked fine, and we noticed that it wasn't detecting any type of disc (CD, DVD, BD (games, movies, music)). Then I tried opening Iris Manager and gave a problem about the payload not working. So I decided to change the firmware to 3.55 OFW again to test the drive. The drive still wouldn't read any type of disc. Does anybody knows if the drive is 100% dead? Or is it another error? I remember someone said that if the drive was dead, you couldn't change the firmware.
