Update the Medion to latest firmware from within the NAS web interface if possible.
You will need a serial connection and terminal console software on your PC (see the "Serial" section) between your PC and the Medion.
This worked for me - PL2303HX USB To TTL RS232 module and firmware version 333, the driver is available at http:// bit.ly/prolific333
An ethernet connection between your PC and the Medion, with your PC's ethernet interface set to static IP 192.168.50.2
A TFTP server on your PC, serving the initramfs-uImage
The image files. From https://downloads.openwrt.org/releases/19.07.3/targets/oxnas/ox820/
openwrt-19.07.3-oxnas-ox820-mitrastar_stg-212-initramfs-uImage (rename to initramfs-uImage as dots confuse the TFTP transfer)
openwrt-19.07.3-oxnas-ox820-mitrastar_stg-212-squashfs-sysupgrade.tar
openwrt-19.07.3-oxnas-ox820-mitrastar_stg-212-squashfs-ubinized.bin
Open the serial connection and power on.

saveenv
setenv serverip 192.168.50.2
setenv ipaddr 192.168.50.1 (use direct ethernet cable between PC and Medion )
