Did you know the build no of your phone? And What actually happens to the phone before flashing the firmware?

do you remember the original build number of your device before flashing?
what was wrong with the device before you decided to flash?
and is the phone totally dead (no screen lights) OR powers on, screen lights show up, you hear the boot sound but no display?

the original build number is KA7O-H8024DEFGH-O-181012V157
the problem before I flash the firmware is if I let the screen goes off it will not show image on screen until I restart it by long pres the power key
the problem after flash is it will power on but will just show light

there's firmware for the build number you posted @ https://www.hovatek.com/forum/thread-24299.html ; try flashing the same firmware build
might be a bug from that rom, esp if you upgraded the phone
when the phone shows light, does the light go out upon releasing the power button OR the lights remain on and you hear the boot sound?
