Sorry for the brevity. I am using my father's cursed iPhone.
You need root
You need a custom recovery
It is not necessary to be on 4.2.1
Good Luck!!!
Thank you for the advice. Already unlocked,rooted with twrp, but decided to try ocean browser first and it FLIES compared to chrome. Trying to fix another issue I found this morning with games shutting down completely before moving on to trying this browser which I'm sure is awesome!!!!!
