In this tutorial, you will learn to revert  TP Link TL-WR841ND router running Linux based custom dd-wrt firmware back to original factory firmware. The advantage of running factory firmware is that it is lightweight and gives you better performance. This procedure requires you to have a Windows OS computer. In addition, it also requires you to have TFTP server software installed.

Step 1: Download original router firmware file from TP Link website:
https://www.tp-link.com/no/download/TL-WR841ND_V9.html

Step 2: Extract the zip file and rename the .bin firmware file to wr841nv9_tp_recovery.bin and place it into a folder called recovery.

Step 3: Download and install TFTP server from the following website:
https://sourceforge.net/projects/tftp-server/

Step 4: Connect Ethernet cable from router LAN port to your computer's LAN port, disable wifi. At this point you will lose internet connection, this is how we want it.

Step 5: Manually change your computer's IPv4 address information to the following:
IPv4 address: 192.168.0.66
Subnet Mask: 255.255.255.0

Step 6: Launch the TFTP Server software and select the current directory to be the recovery directory containing the wr841nv9_tp_recovery.bin file and for the server interface select 192.168.0.66 option.

Step 7: Power cycle the router and hold the reset button for up to 4 seconds.

Step 8. Wait for a few seconds, the firmware will be loaded onto the router and the router will reboot automatically. Note that this process may take up to 2 minutes, do not turn off power during this process.

Done! At this point, you should have your router back to original factory firmware setup, you can confirm by visiting http://192.168.0.1/ to verify it. This same procedure applies to unbricking your TP Link TL-WR841ND router.
