I followed the instructions on the team xecuter and xboxscene for flashing the bios. I did as told and dowloaded the bios from xboxscene from the legal bios is gave for xecuter modchip. I have the xecuter 3 chip with xapter. Put the bios and dummy file on the CD and burned as the insturctions said. Put it in the xbox and everything flashed fine and shut down. Now it will only start in the MS mode. When try to start with modchip I get a couple of on/off shutdowns and then flashing red/green. The bios I used said"cromwell customized version with the xecuter 2 modchip and to be used freely by others. V3.0.3. Any suggestions????? Please help!!
