okay so i had to switch my old pcb to new one, cuz i broke it while flashing... the guy who sold me the pcb flashed it with my dvdkey (he's professional) (i had to solder the pcb to my drive) but now, when i turn xbox on, it opens the disc drive automaticly, and when i click eject to close it, it closes it but after like a second it opens it again and shows a red light in the drive for under a second (the drive is upside down atm)

whats wrong with it, and how to fix? please help

edit: also when it opens the drive it says on the screen "opening" and when i click eject to close "closing" and the green light is flashing on the xbox

It is likely that you either mixed up some wires, or bridged some solder. Check that your wires are in the right order, and recheck your soldering with a multimeter. Look for images on google or somewhere for reference to the order of the wires. I'm at work, so I can't provide links.

Good luck!

i'm assuming you are talking about a slim drive, check your wires, also check if u broke the tray status switch.

im talking about liteon phat drive
