    try hold the reset button for about 10s.
    it's a pity that void the warranty if the router is defective after updating the third-party firmware,

    Hi,

    Sorry to hear, as for the OpenWRT - especially the Huntsman firmware is great - is normally does not cause your route to be bricked. Try the following:
    At the back of the router (next to the blue WAN port) there is small reset button.
    Step 1: Press and hold the reset button for 30 seconds then while still holding the button, disconnect power.
    Step 2: Keep holding the reset button for another 30 seconds then plug the power back in and continue holding the reset button for another 30 seconds
    Step 3: Release the reset button and let router boot.

    This is called the 30, 30 ,30 second reset :-)

    Let the router boot and after a while you should see a TP-LINK_########## wifi network from your PC or Laptop. Have a look at the bottom of your router there is a big label. At the bottom right of that label, there is a SSID and a KEY. This is your routers default wifi - use that key to connect via Wifi to your TP-LINK_######### wifi. You should now be able to access the config page of the router by either 192.1681.1 or 192.168.0.1 webpage (might have to give yourself a static ip. Load the first release Firmware from TP-Link back onto your router and all should be back to normal. No you can try to load the OpenWRT firmware again or stick with TP-Link firmware.

    BIG NOTE!
    Before loading the OpenWRT Firmware, you HAVE to reset the TP-Link Router to factory default !! Otherwise you will have this kind of problem.

    All the best

    MR3420 is a great router, have been using it for almost a year. The original firmware has some problems because when it switches from WAN to 3G it sucks there. The fix for me was this tutorial Fix TP-Link TL-MR3420 v2 3G/LTE Failover . Since there the routers works flawlessly.
