Anyone know if it's safe to update to global 8.1 straight from the Three UK branded 7.1.1 version?

How do I install this on a three branded handset only got phone today so if Any one could post a guide I'd be most appreciated
Download the Global Rom and unzip it. Make sure ADB and fastboot drivers are installed on your PC. Open command prompt with Administrator Privileges. Change directory to where you unzipped your rom, type ADB reboot bootloader, run the command flash_all.

Edit: make sure you have usb debugging enabled on your phone

This will show you the exact process mate. Yes this will update with razer instead of three. You won't have to hang around for three to release updates

Love this phone but Substratum/Andromeda still doesn't work on 8.1, still a conflict with Razer theme engine? Any way to disable Razer theme engine under root and enable substratum?!?! Or any other way short of flashing LOS, which I tried and failed to do?
