After doing some research and apparently not doing enough, I have killed my xbox360, it wont boot either standard xbox dash or NXE/Freestle, just comes on and the power light stays lit, no video. I was researching Xbox dash updates through xbox live and ran a live update on the regular nand side, standard xbox side( I have a demon and coolrunner running), blue switch off. It updated, it shut down and I expected it to come back which it did not. I thought oh well, I can always boot the coolrunner side to fix it, but that doesnt boot either. I have a deamon phat zephyr and coolerunner install with the switch on the front. I can access my Orig nand and deamon chip via usb and jrunner, I have my cpu key. What can I do to get functionality back to my unit? It wont boot either side. Am I screwed here?
