I've had the same flashing problems as you. Progress went to 25-50% and hung. So I flashed it with X2 4977 (previous matrix install) booted evox tried to flash but didnt work until I added to evox.ini (Flash = 0x01AD,"XECUTER 3",0x100000) but it still fragged when trying to boot from a >1024k bank. I did get M8 to work though, but what the hell is it for? So I resoldered my LPC ( thread
) and presto! X3 config live was on the screen. Then I changed my video settings and had more probs, but thats another story, hope this helps.
