any suggestions on how to fix this? updated to the Mar 2020, extracted the boot image, patched in Magisk, flashed, and rebooted like I have done with the previous updates, however once the device is booted up all I get is a black screen! device is still responsive as pressing the power button brings up a menu allowing me to shutdown or reset. flashing a non-modded boot allows me to use the device normally again. help!
