Firmware version 4.02.6 is an official Radioddity firmware not the OpenGD77 firmware.
However, this sounds like the feature (or bug) in the official firmware which I'm afraid prevents the firmware being updated again, without taking the radio apart and uploading using a hardware programmer connected to pads on the PCB
Sir,

Thank you for the reply.

I suspected as much.

You are not the first person who has encountered this problem.

I have replied in detail to someone else about how erase and reload the CPU (MCU) chip by connecting to the SWD pads on the PCB

Its not a difficult job, but you would need to buy a programmer dongle to do this.
