I just installed a X3CE in my v1.0 XBOX. The first time it started, it came up with the flash bios 3.0.3 screen. I selected http and installed X3 3294.bin, and it successfully flashed eprom (displayed yellow bar, green bar, then turned itself off). When I turn it on, it beeps and won't boot. If I hold in the button it will boot into the microsoft one with no problems.
I also tried installing from the backup rom and get the same results. I've tried flashing to both banks with the same results. I also tried flashing without the front display connected.
