I installed a Matrix Infinity chip on a V4, I tested it & played my PS2 originals/backups fine. I gave it back to my friend and he says it stopped working. I have it back now and it wont play anything. All I get is RSOD for originals/backups and PSX games just come up with audio.

I opened it up and noticed my B connection had come loose. I reconnected it but still get RSOD for PS2 originals/backups.

Any help is appreciated.
