Xbox 360:NAND Recovery using a Donor NAND

In the event that you lose your original NAND dump, you can create a new one called a "donor NAND".

JRunner
JRunner With Extras is maintained by Octal450 with work from various community members. JRunner has the function to create a donor NAND for any console with only a CPU Key and a LDV (Lockdown Value) of the particular console.

How To Locate Lockdown Value
LDV can be found by booting XeLL and counting the number of "f" characters in your fuses from lines 7 to 11.

Process

 * 1) Open JRunner and click the "Nand" tab, then go to the "Create Donor Nand..." tab.
 * 2) Select your motherboard type, click "Ok".
 * 3) In the Xebuild portion of the main JRunner application select your dashboard and glitch type.
 * 4) Click "Next" in the donor nand window, paste your CPU key in the field.
 * 5) Check "Donor Keyvault" if you do not have your original keyvault. Note this will effectively make your console act as if it is banned. Click "Next".
 * 6) Enter the Lockdown Value in the "LDV" selection, and leave "Donor SMC Config" checked.
 * 7) JRunner will confirm the information you have entered, and ask you to click the "Finish" button.
 * 8) JRunner will then generate your donor NAND. The NAND will be located in another folder with numbers as the name, the specific folder can be found in the JRunner log.
 * 9) The NAND can then be flashed using XeLL or any homebrew NAND flasher, as well as hardware flashers.
