I just finished a Matrix Infinity GD install on a PS2 V16 (or latest edition V14). I get the matrix screen, can get to the matrix setup screen, and can boot original discs, but I can't do much else. The seller, modchip.com, said that the chip came with homebrew firmware, but I can't figure out how to upgrade this sucker since I don't have a blue reset light like earlier ps2's. I've tried holding the power/reset button for like 2-3 seconds but nothing happens. Also sometimes it freezes on the matrix screen. Anyone who has gone through this, I would appreciate your help.
