Depends on what version of raincoat your gamesave contains. If it is v0.5, it will flash when it is executed. If it is 0.7. you will need to use telnet to issue the commands to the xbox from a PC. In windows 7, telnet may be disabled by default. To enable it go to the control panel (category view) and then select programs. Then select
Programs and Features. On the left, select "turn windows features on and off". When the window pops up, select the check box for telnet client.
When you hear the sounds on your xbox go to your computer and change IP address to 192.168.0.1. Telnet to your Xbox using IP 192.168.0.64. Login with root and password xbox. To get the raincoat directory, "cd /media/E/UDATA/4d520017/62D648EBF155/raincoat" (without quotes). copy the raincoat config, "cp raincoat.conf /etc/raincoat.conf", and backup the current/original bios, "./raincoat -r originalbios.bin".
Flash the TSOP with the raincoat flash utility with "./raincoat -p bios.bin". Once this is done, get the AID 4.52 ISO and burn it to a DVD. Boot that on the xbox and use it to install the dashboard of your choice. I recommend either UnleashX or XBMC.
