Yes. But donor is a bin file on the STM32 radios
Ah, yes, true.

Firmware validity checking will be part of the next release.

Hi,

I just ran into the same issue with a white screen after installing the latest stable version for the uv-380. I used the latest CPS as well :(

UPDATE: I was told that it was a ribbon cable issue. I was doubtful since the radio worked before the firmware updates, none the less I opened the radio, reset cables and everything works jsut fine. I was puzzled how a radio sitting on a desk would work one minute and stop the next when all I changed was the firmware. I am starting to believe that there is a tiny "Neo" moving from the computer world to the real world in this radios using GD77 to travel in and out :)

When you plug in the cable to update the firmware there is a significant force applied to the PCB and things move slightly inside the radio. A connection that is only just working could easily be disturbed and stop working.
