So today i remember holding down power+vol key down and got install custom rom, me being a noob i press vol key up for Yes, not knowing that it will give me custom Device status, i never Rooted my phone nor unlocked it, just was curious what it will do... well now i cant update my phone because i get and error Update, it gives me Your device has been modified. Software updates are not available?? any way to revert back to normal?
