Amiko spiel blocked

Good afternoon!
I have here an amiko spiel, which is blocked, it connects normally but then it stays in a state that does not let me do anything, nor go to the menu, nor change channels, nothing!
Can someone tell me what tool to send the firmware for rs232?
greetings


PS: Or if there is a way to boot the device and send the firmware automatically with a USB stick?

After some research, here it is:
The software to upload via rs232

UARTUpgradeToolv2.2.8.126.rar

And even easier, by pen usb:
Put the firm or backup on a pen.
Rename to ROM.bin
Switch the receiver on the back button with the channel + button pressed (front panel)

Anyone know which channel editor for amiko spiel?
