How to Flash a New XBox 360 DVD Drive
Xbox 360 consoles are manufactured by Microsoft and use an internal DVD drive to read game and movie discs. These DVD drives are manufactured by several different companies, including Samsung, Hitachi, and Phillips. You may need to "flash" a new replacement DVD drive for the Xbox 360 if your original unit is defective or breaks. Flashing the DVD drive will configure it for use with the console and can be done in about 15 minutes.
Instructions
        1
        Disconnect all cables from the Xbox 360 and remove the faceplate from the front of the console. Lift the plastic tabs on the outer shell and remove the plastic casing from the machine. Unscrew the Torx size 7 screws and lift open the metal cover. Unplug both the power and SATA cables from the rear of the DVD drive and lift it out of the console. Replace it with the new DVD drive, and connect the power cable to the unit. Connect your SATA cable to the DVD drive and a free SATA port on your computer.        2
        Turn on your computer and open a web browser. Download JungleFlasher and run the program.

Click "Flash .BIN to DVD" in the program's main menu and select your Xbox 360's DVD drive. The program will flash the new DVD drive for use with your Xbox 360 console. dreambox dm800        3
        Turn off the computer once the flashing process is complete and disconnect your SATA cable from the DVD drive and your PC. Reconnect the Xbox 360 SATA cable to the new DVD drive, then close the metal cover on the console. Rescrew the Torx size 7 screws and replace the outer plastic shell on the Xbox 360. Return the faceplate to its original position then reconnect all external cables and accessories to the console. Power on the Xbox 360 and the replacement DVD drive will function normally.
Tips & Warnings
