Here is a test file for the 940N v6 BR.

TFTP flashing as follows (mostly as root user):

- on ubuntu 16.04 machine, apt-get install tftpd-hpa
- in /etc/default/ create file tftpd-hpa containing:
TFTP_DIRECTORY="/tftp"
TFTP_OPTIONS="--secure --create"
TFTP_ADDRESS=":69"
TFTP_USERNAME="tftp"
(note I saw other "help" posts where the above were smart quotes Sad, or were only single-hyphen options Sad, or were a backslash on the directory Sad, all of which were gotchas, be careful with copy-paste!)
- mkdir /tftp
- put factory-to-ddwrt-us.bin into that folder, renamed to wr940nv5_tp_recovery.bin (probably -eu.bin would work too, renamed the same)
- chown -R tftp:nogroup /tftp
- disconnect from wifi, use LAN wire to LAN port of router
- in networkmanager, modify existing or add a wired ethernet connection, on Ethernet tab pick a Device: eth0 or whatever it offers you; on IPv4 Settings tab, method: Manual, address: 192.168.0.66, netmask:24, gateway: 192.168.0.1 (some pages said the router will be .86 but I can't recall if I tried that for gateway), save and enable that connection
- service tftpd-hpa restart
- power off the router, and while holding pointy thing/paperclip etc on the reset button, power on the router, still holding reset button until the padlock LED comes on (about 3-5 s)
- wait a bit for router to fetch .bin file by TFTP (I don't know how long I waited or which LEDs changed in this time; also I couldn't find if or where the TFTP server was logging this access on the laptop)
- in networkmanager, change back to the automatic (DHCP) wired connection or enable wifi
- browse to router at 192.168.1.1, should see dd-wrt interface now instead of tp-link branded interface
- change default password, wifi password and all other dd-wrt features for which you did all this Smile
