I have a v1.0 Xbox, with a homebrew and I flashed the tsop along time ago, home brew is still installed w/disable switches. Now I just bought an X2pro, and want to beable to get on Xlive and stuff. Which BIOS if any can I put back on the TSOP if I didn't backup, to get on live. Theres another problem though since I've flashed tsop the homebrew won't boot, and I've double checked all the wires and I have good connection. If I can simply flash the TSOP with the 3944, 4034, or 4132 , and my manufacture date is 10-19-01, please let me which I should flash. Cause I wont get a second chance .

well just go look on irc for a normal bios

wierd that your modchip doesnt boot... somethings wrong there, should sitll boot to the bios on the mod
