how to unlock my phone when it is flashed with unauthorized software

[AC Question]

ok so i rooted my phone with kingroot and then turned my phone off. when i tried to turn it back on, a screen came up with a yellow caution sign with words under it that said your phone has been flashed with unauthorized software and is locked

Reflash your stock firmware and STAY AWAT from King root if you want to keep a reliable device.
