What Happenend?
KV was already banned
KV type was different from JTAGs version
Flashed the WRONG way

What You Need
Original NAND Dump renamed to UPDFLASH.bin
Working USB Drive
Computer
Screwed Up JTAG

How To Fix:
1. Drag the working updflash.bin into the root of the USB Flash Drive. (For noobs, it means dragging it to USB)

2. Turn off the JTAG system

3. Unplug ALL Cables from JTAG

4. Plug your USB into preferably the front slot of your JTAG, use the OPPOSITE slot you flashed in.

5. Connect the AV Cable

6. Connect your Power Brick/Cable

7. Plug your JTAG into Power Outlet

8. Turn your xbox Via the **Eject button thus starting XeLL**

9. Wait for XeLL to finish updating

10. Power Cycle

This Should Work, if not you need a Geek to open your system and connect your wireless adapter for your controller to a USB port with ExDrive.
