Things You'll Need
Instructions
Plug in the SATA cable from your PC to the 360&'s motherboard SATA connection after removing the console&'s case. Do not disconnect any hard drives from your PC&'s SATA ports, as this will cause your operating system to fail to boot up correctly. Use a separate SATA port on your PC to connect the 360&'s motherboard.
Power on the computer and run your web browser of choice. Download JungleFlasher and install the application.
Run JungleFlasher and click your Xbox 360 motherboard from the drop-down menu. Choose "Edit EEPROM" and select "OK." The JungleFlasher program will copy your Xbox 360 motherboard&'s original EEPROM for editing on your PC. The JungleFlasher application will create your altered EEPROM for "flashing" or copying from the PC to your console via the SATA cable.
Choose the EEPROM file you want to send to the Xbox&'s motherboard and select "OK." The program then will write the EEPROM file you chose to the motherboard via the SATA cable.
Completely reassemble the Xbox 360 before powering on the console again.
