Support for Cudy WR3000

So serial console is your only hope then. Look for the steps I've did

and then load image openwrt-23.05.0-rc3-mediatek-filogic-cudy_wr3000-v1-initramfs-kernel.bin via tftp

Then when Your device is booted You flash openwrt-23.05.0-rc3-mediatek-filogic-cudy_wr3000-v1-squashfs-sysupgrade.bin
