I have modded numerous xbox's before with no trouble using the spiderchip (via pinheader). I ordered some Xecuter 2.6 lites and on my first install (Xbox version 1.0) I hit a bump. The cromwell (Flash 3.0.1) bios comes up fine. When I try and load bios from CD (X2 4983.06 - same one I have always used) it looks like it flashes fine. It goes into flashing mode, the progress bars fill up, and the xbox shuts down. But when I turn the Xbox back on, it goes back to the cromwell bios. (Yes the flash protect is turned off). I have tried flashing both banks. I followed the X2.6 flash tutorial http://www.teamxecuter.com/biosimage.htm to the T and am about out of options. Anybody have any suggestions? Any help is much appreciated.
