Can't use android pay after removing root
Turned out I had to re-flash firmware for it to work. Instructions for re-flashing firmware for my specific device (lg g3) were incorrect which bricked my device. Luckily I found that clicking the other action mode than the one stated did the trick and my device was un-bricked. Was a scary few hours. At the end though my lg g3 worked and all residue of kingroot was gone!
