A

AC Question

I have lg g3 more than a year, android 6.Last night I rooted it and installed twrp with TWRP manager after that it asked me'do you want to go recovery mod', and I taped yes, suddenly it turned off and did nothing.
I tasted a lot of ways, for example I put out battery,sim and sd card, after that connected to charger and after it showed error logo I pulled battery and the screen got dark with LED off.
please helPPPPP
