So I plan to get a 6P as my next phone. I know the new Pixels are coming out soon but I prefer to stay a flagship behind for the sake of expense. I'm on a galaxy S6 right now. My main reason for getting the 6P is a desire to rooting and ROMing again. My question: is there anything I need to know about firmware version or updates that will make cause me problems when rooting. I found out this info too late with my S6 and after updating to the current firmware, unlocking the bootloader is no longer an option.
