Go to the downloads section and download the "ozxflash software". Burn it to a disk. Then find some hacked X2 bios (4977 is best in my opinion). Then, make sure the bios is the correct size (1mb i think, don't try anything untill you confirm or someone here does though). After you have the right size, rename it to "bios.bin" and burn it to a cd-rw, with nothing else on the disk.
You should have
-ozxflash
-disk with only bios.bin on it
After, just load up the ozXflash software, it will open the dvd tray automatically (do not press the eject button), then replace the disk with the bios one. DO NOT CLOSE THE TRAY. It will automatically close after a minute or so (a message will display telling you not to close the tray). It will then flash the bios and power off. As long as your ship wasn't write protected, it should have been flashed and working.
