so , i was trying to root my device
when i was in twrp ( last version ) , trying to install supersu . and the "Swipe to unlock" message appear
but i can't swipe
tried to turn off the device , but it won't turned off
after a minutes , the screen turned off
so i tried to press the power again , still in that screen and message and i can't swipe
if i plug it PC , it recharge

i heard if i press and hold the power button under strong light it will recognize or something , not sure if that a joke


its seems the screen not responding
