This method works great.
I installed clover to usb then stuck my kext from my extra folder in to the efi kexts folder and dsdt.aml in to root of usb.
Rebooted from usb and took not of the s/n it gave me + 1 to 6 in numbers added it to the config.plist and rebooted with usb stick
Imessage then gave me an error about i could not use this apple id contact support.
I signed in on my iPod then retried and bingo all working fine.
The bonus is now when i boot into chameleon its stays logged in as i had boot1 error trying to install clover to my hdd
in plist file
