Things You'll Need
Instructions
Open the 360&'s case by unhinging the plastic casing from the 360&'s metal cover and removing the Torx size 7 screws with the screwdriver. Unplug the 360 &'s DVD drive from the motherboard and plug in the SATA cable from the computer to the 360&'s DVD drive. This let you flash TSOP files from your PC to the console.
Turn on your PC and open your web browsing program. Download JungleFlasher (see References) and install the freeware application when the download completes. JungleFlasher is currently the only application that can replace TSOP on your Xbox.
Open the JungleFlasher application and choose the console&'s DVD drive from the drop-down bar. Select "Edit TSOP" and click "OK." The JungleFlasher application will copy the console&'s TSOP file for modification on your computer.
The JungleFlasher program will make an altered/edited TSOP file for flashing from the computer to your Xbox&'s DVD drive. Select the TSOP file you want to flash to the console&'s DVD drive and click "OK." JungleFlasher will copy the edited TSOP file to your Xbox&'s DVD drive.
Return all screws and reassemble all console and computer hardware before turning the Xbox 360 console on again.
