I've found out that even this particular entry level router supports anti-bricking, so there's no need for soldering, unless of course you are modding. The method I used is the following: Set up a tftp server on your PC and verify if it works correctly (configuration, permissions, firewalls, etc.) Rename your target firmware to wr740v4_tp_recovery.bin and copy it to your base folder (by default /tftpboot). I tested with openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-factory.bin r43602. Set up the following static IP for your PC: 192.168.0.66 /255.255.255.0. If you're not sure about the firmware name on a different model, start a packet sniffer on your PC ( tcpdump -i eth0 -n -l ) and look for the name in the RRQ message. Preferably disconnect WAN from the router Connect the PC to a LAN port Power off the router Press and hold the reset button Power on the router After the leftmost (power) LED and the rightmost (padlock) LED turn on alone in a few seconds, release
After exchanging mails and phones, they promised calling back. They never did yesterday, though thankfully the domain is now out the status of closing down. Mail delivery is now operational and the site is hosted once again.
