@sergeBa
did you flash modified FW via GUI or recoveryloader?
I have opened AirLive FW by means of the HEX-editor, have found line OVS_RUS021 (it repeats five times) and have replaced it on DDC_RUS021, have written down changes. After that it is possible to load under the instruction:
1. Please power off the device.
2. Push backup and shut down reset button don’t release then power on.
3. Still not release button, then see the usb1,usb2,status/backup, hdd status LED light or not? If it light,
then release the button.
4. If so, then use the DOS command line also put the new firmware on your computer c:\ folder
tftp -i 192.168.123.254 put FW.bin (use the new firmware)
5. After done then reboot.
I think as on MGB111 it will work. Only it is necessary to define a line for MGB111.
