downgrade back to kitkat. then use my guide to sim unlock (or if already sim unlocked use guide to get MF1 Modem that is susceptible to T-mobile hack) then follow the guide you listed. then once you get that far use my method to upgrade to lollipop while keeping the MF1 modem... that should work. let me know.
