Current Dashboard: 16202

Things you will need:
-XeBuild GUI 2.088
-Backup NAND
-CPU Key
-USB Flash Drive (Formatted to FAT32)
-Flash360(if you don't have your NAND backed up)

Instructions:
Skip to step 5 if you already have a backup NAND and your CPU key
1. Boot into XeLL (with the console turned off, press the eject button)
2. Copy CPU key down onto notepad (if you are connected via ethernet to your network, simply type in the IP address and then copy the CPU key from there; if you are not, manually copy the code)
3a. If you are connected to the network page (for XeLL), click "download" next to the "Raw Flash" section
3b-1. If you are not connected to the network, run flash360 on your Xbox (place on USB drive and launch using XeX menu, FSD, etc)
3b-2. Press X to backup your NAND
3b-3. Once completed, exit the application
4. Power down the Xbox (and remove flash drive if you used flash360)
5. Launch XeBuild GUI 2.088
6. Click open next to source file and select your flashdmp.bin
7. Click save next to output path and select the root of your flash drive (save as updflash)
8. In the keys section, paste your CPU key
9. At the bottom right of the screen, press check KV (this makes sure the CPU key is correct and will properly build your image)
10. In kernel version, select 2.0.16202 (if not already selected)
11. Double check build type, motherboard, XeLL, and SMC Hack (JTAG ONLY)
12. Press "Generate Hacked Image"
13. Once completed, unplug your flash drive
14. Plug your flash drive into the Xbox (with the console OFF)
15. Boot into XeLL (press eject button with the console off)
16. The image should begin to flash (rawflash v4 initiated, etc)
17. Once complete, power down the Xbox
18. Unplug flash drive
19. Power on the Xbox
