Once you have obtained a kv.bin and its corresponding cpukey.bin , there are two main ways to "download" or install them onto your console: 1. The Stealth Server Method (Easiest)
The unique "fingerprint" used by Xbox Live for authentication.
If you have an unbanned spare console, you can use tools like J-Runner With Extras to dump its NAND and extract the KV_dec.bin .
Place the kv.bin and cpukey.bin on the root of your console's hard drive ( Hdd1:\ ).
