please need help very urgently. i was trying to install a custom rom in my phone today. unlocking bootloader was successful, installing twrp was successful too and i was very happy. when i tried to boot into the recovery it turned off and never booted. tried restarting (volume up+power button), pressing the power button but nothing happens. it's still in the "off" state. please don't think it is a bootloop. the phone doesn't turn on and i can't see the logo. seems like it is permanently turned off
