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
Currently running exactly that. Only ever had minor problems with closing certain resource intensive apps (sometimes they hover on screen when switching between apps) although very rarely.
Otherwise, couldn't be happier.
Installing was just following the website instructions: press to unlock bootloader -> press to flash image -> press to lock bootloader.
Bro just pay attention bro just focus on what you're supposed to be doing bro
