I will need some easy-to-follow steps if at all possible. I'm in need of being able to backup apps, contacts, data/pictures/etc before I flash anything (I assume I will lose all of them). I'd love recommendations on a good ROM to suit my needs too. I guess I'm feeling a bit overwhelmed and not sure what I can do and then exactly how to go about it without losing anything or bricking my phone.
current build: I545VRUEMK2
Thank you in advance for your patience and help!
