Ok Slight Problem..... I follwed the instructions:
Extract xell-2f.bin from XeLLous_v1.0.zip and rename it to updslot0.bin
Copy updslot0.bin to a USB stick and put it in your 360
Start XeXMenu (or FSD), Navigate to the root of your USB Stick and run Flash360.xex
Press button B, press button A.
Follow on screen instructions to exit and shut down from Flash360 (do not exit via guide button)
Once console has shut down, remove power for at least 30 seconds to allow for a complete reinitialization of console.
Remove USB stick
Replace power and boot console via the eject button to boot into XeLLous.
This give s me a black screen on both pressing eject button & normal start up for NXE
Next i restore my original nand using NAND-X first writing Xellous the restore backup of nand.
Xellous is now installed but reports that DVD key is all zeros. ????
If I restore Xell & Original nand and then try to update using Xell I'm getting an error. "unknown hackimage version"
