I just installed an Xecuter 2.6 modchip in my xbox, and I tried http flashing it with a 512kb X2 4977 bios file. The flash protection was off, it was set to bank one, and I uploaded it and sent it to flash, and it gave the Unknown Flash! Halting. error, so I reset my xbox, and now all I get is a FRAG, or sometimes, it turns on and just stays orange... Any ideas whats going on here?
