I had the same black screen after flashing two GD77s with the beta firmware, but I think I figured out the issue!
On both of them flashing the beta firmware seems to have turned "Safe Power On" to ON. Unfortunately, when you turn on the power there is no indication of what is going on since you get a black screen so it looks like it's bricked.
To fix it all I had to do was hold SK1 while turning the power on and then go to "Options=>General Options=>Safe Pwr-On" and turn it OFF. After that they both worked fine.

My Baofeng DM1801 with the beta update stop working (bricked)and no sign of life.
The procedure that worked for me was to remove the battery and then press sk1 and sk2 and then insert the battery back, in this way, the green led turned on and the radio came back to life..

Press SK1 while powering-on, the setting "Safe Pwr-On" is enabled. https://github.com/LibreDMR/OpenGD77_Us ... e-power-onpu7olw wrote: ↑Fri May 26, 2023 12:14 amMy Baofeng DM1801 with the beta update stop working (bricked)and no sign of life.
