Migration to OpenWrt:
- Download the RSA signed intermediate firmware from the Cudy website:
  `openwrt-ramips-mt76x8-cudy_lt300-v3-squashfs-flash.bin`
- Connect computer to LAN and flash the intermediate firmware via OEM web interface
- OpenWrt is now accessible via 192.168.1.1

Revert back to OEM firmware:
- Set up a TFTP server on IP 192.168.1.88 and connect to the WAN port (upper port)
- Provide the Cudy firmware as recovery.bin in the TFTP server
- Press the reset button while powering on the device
- Recovery process is started now
- When recovery process is done, OEM firmware is accessible via 192.168.10.1 again

General information:
- No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot
