Hello everyone, I recently flashed a sound mod onto my LG G2 running 5.0.2 Lollipop and now my sound doesnt work :(
I used this mod:

and flashed the Headphone6319.zip file using TWRP recovery.
Now when I try to play music it says "Sorry, the player does not support this type of audio file" even though it was playing perfectly before! PLEASE HELP!!!:(
