Flash instructions:
  1. 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. Execute the following operation to open nc shell:
     https://forum.openwrt.org/t/tp-link-china-routers-rce-vuln

  3. Download the preloader.bin and uboot.fip, host them with
     the HTTP server: python3 -m http.server

  4. Replace the stock bootloader to OpenWrt's:
     ln -sf opt/game_acc/rootfs/bin/busybox wget && cd tmp
     /wget http://192.168.1.254:8000/openwrt-mediatek-filogic-tplink_tl-7dr7250-v1-preloader.bin
     /wget http://192.168.1.254:8000/openwrt-mediatek-filogic-tplink_tl-7dr7250-v1-bl31-uboot.fip
     dd bs=131072 conv=sync of=/dev/mtdblock15 if=openwrt-mediatek-filogic-tplink_tl-7dr7250-v1-preloader.bin
     dd bs=131072 conv=sync of=/dev/mtdblock15 seek=44 if=openwrt-mediatek-filogic-tplink_tl-7dr7250-v1-bl31-uboot.fip

  5. Download the initramfs image, host it with the tftp server,
     and restart the router, waiting for tftp recovery to complete.

  6. After openwrt boots up, upload sysupgrade.bin to upgrade.
