I have installed my modchip appropriately (triple checked it) and while trying to flash the bios, the status bar got about 1/3 of the way complete and then locked up. I let it sit for about 5 minutes, while nothing happened, before shutting off my XBOX. Now all it will do is FRAG. I have tried a couple of tricks I've seen in other forums, such as holding down the power & eject button for >1 seconds and I've also tried holding down the white & black buttons on the controller. Neither solution worked. Can someone please help?
