I have the same problem.

When I press side key 1 and side key 2 the green LED flashes and nothing appears on the LCD screen.

Please your expert help.

Probably the copy protection data in your radio has been erased by the official firmware.

The only solution is to use a hardware dongle programmer connected directly to your radio PCB, to erase the CPU and then install a patched bootloader which does not check the copy protection data
