Dont fret about it, really. It's not quite as smooth as I made it seem since you still have to manually switch some options, but it is abundantly clear what steps you must take and how to take them.

Just don't skim the steps like I first did, I think I almost bricked my phone before i realized what i was doing. Reading the instructions and doing precisely what it tells you is easier and simpler than you think, also helps a lot in not ruining 250$ of hardware
