My problem started when my slim with the unlock PCB v1.0 received the open tray error, and yes I tried every fix. To start things off I then bought a new laser thinking it was the laser. Then after that failed I tried replacing the drive. No luck! I was then convinced it was the PCB board. So decided to order the V1.1 Now after installing the board my disc tray won't even open. When I flashed it I flashed it with LT 3.0. I am really stuck here. Please someone help!!!!!
