Second problem: I don't know if my boot loader is unlocked. The reason I think this is because when I used the manudroid19 toolkit to unlock the boot loader, it restores my system, but when I try to flash a custom ROM, nothing happens. People I've talked to say that its supposed to stay in fast boot mode for about a minute before it actually boots into TWRP, but nothing actually happens.
Third problem: when I press the root button in manudroid19, nothing happens. The cmd prompt just pops up for a split second then nothing. Plain out nothing happens. Root Checker says my phone is not rooted.
How would I resolve all of this?
