02. Install CWM Recovery and Root Phone

sudo adb reboot bootloader

Then

sudo fastboot flash recovery recovery-clockwork-touch-6.0.4.4-hammerhead.img

Just left to remember: Install libmtp

sudo mtp-connect

Forget that and install mtpfs

pacman -Sv mtpfs
yaourt go-mtpfs-git

You may have to remove reference to go.sh out of the PKGBUILD(I did at the time)

sudo mtpfs -o allow_other /media/temp
mkdir /media/temp/Internal\ storage/clockworkmod/romsanstuff
cp UPDATE-SuperSU-v1.65.zip /media/temp/Internal\ storage/clockworkmod/romsanstuff/
sudo fusermount -u /media/temp
sudo adb reboot bootloader
