How to Restore MR3420 V5 OpenWRT to Original

  1. If the MR3420 is already bootlooped (I call it that for convenience) make sure to reinstall it to OpenWRT using TFTPD (you must already know how to install it via TFTPD because you have already installed OpenWrt before).
  2. If you have returned to OpenWRT then change the Original Firmware to code.bin
  3. Then change the connection of the MR3420 with the laptop using wifi (by default wifi SSID Openwrt)
  4. Open WinSCP and connect to 192.168.1.1, if it is already open please copy it code.bin to tmp folder folder
  5. If it has been copied then open PuTTY with IP 192.168.1.1 and type the following script
    cd /tmp

    press enter < pre>dd if=code.bin of=tplink.bin skip=256 bs=512press enter

    mtd -e firmware -r write /tmp/tplink. bin firmware

    press enter
