Hi! I have just recently rooted my samsung galaxy s4 i545vruemk2 with saferoot. The main reason i wanted to root my phone was so that i could flash a custom rom, (stock 4.2 jellybean) but i do not know how. The bootloader is unlocked. Also if anyone could refer me to any good stock 4.2 jellybean roms that would be great! Thanks! P.s. i am only 13 years old so this is new to me
