I downloaded and unzipped Lunix3-4K_3.0 Firmware.
I inserted the UPDATE folder in USB
I turned off the receiver, USB inserted in the receiver
Handset on: at the desktop message I pressed the power button on the front panel (on / off) of the handset.
It shows me that the installation is starting. It appears on the display of the "Booting ..." receiver and it stays that way, nothing happens anymore.
What else can I do to unlock? Thank you.
I can't put an image, I don't have access to the MENU.
When installing the same as Lunix3-4K_3.0 Firmware is not installed.
Is there no RS232 unlock procedure?
