Migration to OpenWrt:
- Download the RSA-signed intermediate firmware from the Cudy website: `openwrt-ramips-mt76x8-cudy_wr300-squashfs-flash.bin`
- Connect the computer to the LAN and flash the intermediate firmware via the OEM web interface
- OpenWrt is now accessible via 192.168.1.1
Revert 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
- Power on the device and hold the reset button immediately after the first LED blink
- The recovery process will start
- When the recovery process is done, OEM firmware is accessible via 192.168.10.1 again
General information:
- No possibility to load an initramfs image via U-Boot because there is no option to interrupt U-Boot
