I have a v12 Ps2 with the Infinity chip on it. I had firmware 1.38 I believe and decided to upgrade to 1.54. It booted the disc fine and it ran through the upgrade and said it was sucessful. I then restarted the Ps2 and all I get is a Matrix logo on my screen. I can't use the triangle+square buttons to get into the config menu and i cant boot backup games at all. I can boot original games just fine.
Is there a way to reflash this somehow? What are my options here.
