I have a TP LINK Archer C7 v2. It was running 19.07.3 and I downgraded it to 18.06.7 using
openwrt-18.06.7-ar71xx-generic-archer-c7-v2-squashfs-sysupgrade.bin
After flashing 18 the wifis were down, tried also eth and nothing.
So I guess it bricked somehow, I've tried with the tftp recovery but no luck. This is what I'm doing:
set pc ip to 192.168.0.66/24 (tried also with 192.168.1.66/24)
start tftp server with ArcherC7v2_tp_recovery.bin (I'm using openwrt factory image here)
turn on the router while the wps/reset button, holding it until the wps light turns on
Nothing happens, I'm not seeing anything logged in the tftp server (tftp32)
When you turn the router on for a normal boot, does the system LED blink fast, then slow, then come on steady? That sequence means that OpenWrt is doing something. After OpenWrt boots try a reset to defaults by holding the reset button for more than 5 seconds then release it.
To do a TFTP recovery from Windows, make sure Windows Firewall and any third party firewalls are disabled. By default they will block the TFTP request packets to your server.
Turns out I installed another tftp server before installing tftpd32 (solarwinds), I think that wasn't working and left a service running that conflicted with tftpd32. Uninstalled the other server, rebooted, and got it working.
