K, I now have a new chip! And guess what turns out I did not need it, because after all that I had been installing the chip the wrong way round. Dont ask me how and why, I'm just stupid and waisted more money.
But now when I put either of the chips in the xbox goes through this code.
1) Boots up, flashes green, turns off (no video)
2) Boots up, flashes green, turns off (no video)
3) Boots up, keeps flashing red (no video)
This all happens after just pressing the on button once, also it starts up normally with the mod chip disabled! What could all of this mean, I looked at all error codes and it say something about a bad epprom. But with two mod chips?
But I have checked my soldering and it all looks pretty tight!
Thanks!
