This is a tutorial I'm making to help you guys get your jtag xbox back up and running from a bad kv/christmas lights. I'm not sure if this has been released before so please don't flame. Requirements: 1. Extracted flashdmp.bin from flash360 2. Xell 3. Usb flash drive Steps: 1. Re-name your flashdmp.bin to updflash.bin 2. Move the newly named updflash.bin to the root of your usb 3. Plug the usb stick in your xbox 360 4. Pull out the power cord from the back of the xbox 5. Wait 30 seconds (MAKE SURE YOUR USB IS STILL IN THE XBOX AT THIS POINT!) 6. Plug your power cord back in and turn on your xbox by ejecting the disc tray/starting up xell 7. Wait about 2-4 minutes for xell to finish and restart your xbox 8. Now you have a fully working jtag xbox if you followed the steps correctly!
