Here are some quick notes from my dashboard update on my RGH Xbox 360

I am upgrading to dashboard 17489 which is the latest as of today.

Software needed:

  • Simple 360 NAND Flasher
  • xeBuild GUI

Lets do it:

  • Fist put the Simple 360 NAND Flasher on a USB key and run it on your Xbox from XEXMenu.
  • Backup your existing NAND (It will make a file called flashdmp.bin).
  • Open the flashdmp.bin in xeBuild GUI.
  • Make sure to have your CPU Key handy.
  • Make sure the latest dashboard is selected (17489) as of today.
  • Create update NAND (updflash.bin).
  • Copy updflash.bin to USB in the Simple 360 NAND Flasher folder.
  • Use USB in Xbox and run Simple 360 NAND Flasher again.
  • This time it will ask if you want to update the NAND since it detected the updflash.bin file.
  • System will reboot on its own. Check and make sure the dashboard updated.
