Connect to your PC via the Gigabit port of the router, set a static ip on the ethernet interface of your PC. (ip 192.168.1.254, gateway 192.168.1.1) 2. Attach UART, pause at u-boot menu. 3. Select "Upgrade ATF BL2", then use preloader.bin 4. Select "Upgrade ATF FIP", then use bl31-uboot.fip 5. Download the initramfs image, and type "reset", waiting for tftp recovery to complete. 6. After openwrt boots up, perform sysupgrade. Note: 1. Since NMBM is disabled, we must back up all partitions. 2. Although we can upgrade new firmware in the stock firmware, we need the special fit image signature of MediaTek and dual boot (hack kernel) to make u-boot boot it. So just abandon these hacks and flash it via the serial port.
