I'm being a bit nooby here - have lots of experience flashing with Samsung's, but not much with HTC.
I have an unlocked M7, however it was originally locked to EE. (UK). As such, it's still suck on 4.3.
Is it possible to fully convert my phone to the unlocked version of the firmware so that I can receive OTAs? I've read about roms needing to match the version listed on hboot if you're S On (I am) but can't figure out whether it's necessary for functionality, or just for warranty purposes.
Sorry if this is covered already - we all know how great the search function works here...
Cheers for any advice!
