Done on a Xenon without a problem just followed directions in here.

Launch FLASH360 on XBOX from USB key and make a full nand backup (button X)
then on PC launch Easy FreeBoot
Click Create Image
Open saved nand backup
Enter your CPU key
Easy FreeBoot will finish and create a Updflash.bin
Copy Updflash.bin to the usb key (i´ve copied to the root of the usb pen)
Gone to XBOX, launched XeXmenu 1.1 and then runned FLASH360 Xex
Button A (write updflash.bin to Nand)
Button B (Raw Flash without keeping current kv/config).
ignore the warnings ("WARNING: Keyvault encrypted data check mismatch" and "WARNING: Your current nand is not the ZeroPaired."). Pass this with Start button
Pressed A after the 2 warnings to continue with the flash
Wait until it´s flashed
Back
Back to Turn off Xbox 360
It turn´s off by it self
Remove Usb pen
Remove power cord and wait 2 or 3 minutes
Press power button
Now configure language and resolution
Will ask about an update, just press OK (Don´t know if this happens without a live profile, mine is for avatar items)

Anyone noticed the temperature is lower?

Used some posts on this forum, so thanks to those people.

PS: I do have a original nand but i´ve chosen to use the backup made by flash360 as my original nand had CB 120 and freeboot 9199 had Cb 121. So just used what was working this months.
