When I first installed the Xecuter 2.6 chip on my 1.6b xbox and tried to boot with chip disabled the power button flashed red/green. But with the chip enabled it went to the flash bios v3.3. I had trouble flashing the chip using a dvd so i decided to use ftp. So i flashed it with Xecuter 3 bios 3294. Now when I try to turn xbox on it just flashes red/green, with chip off/on bank 1/2. Can you tell me what's wrong and how to fix it.
