Need advice re: bad flash
I recently purchased and installed a Matrix Infinity (not from an official retailer, but it looks exactly like the real thing) in my v4. When I started it up, the Matrix logo appeared and I was able to load DVD+R backup games. I then loaded up Free HD Loader and attempted to flash the chip. The flash utility returned an error and couldn't flash, so I restarted. This resulted in a black screen.
By holding the reset button in for a second, the PS2 booted normally but with no matrix logo. It could play retail DVD games, PS1 games, and PS1 backups. It wouldn't read the Free HD Loader CD-R anymore, nor any other Matrix Update CD-R's.
I've taken it apart and double checked everything, but something tells me it's not the wiring. Otherwise, why would it have started up the first time? I'm thinking my chip is in some unrecoverable state.
Basically I need advice: do I continue to troubleshoot the install, or by a new Matrix Infinity (this time from a reputable site)?
