I got a Galaxy Note 4 from my father and it is the AT&T version. I think it's been already rooted since I can use other networks besides AT&T on it... But there are some AT&T stock apps/bloatware on it which I can't seem to get rid of. Is there a way to or is there a ROM I can flash on it? I heard there were no ROMS for this. And if there is a way to upgrade the PHONE from lollipop to marshmallow. Thank you.
