I have (had =) ) a bricked Archer C60 V2 AC1350.
I readed a lot about TFTP method to debrick the router but, both under Windows or Linux i couldn't make it work, in any way.
I do a verbose tcpdump and i see:
SRV linux-2qx8.local.:22 0 0 (259)
So i simply changed the TFTP server port to 22 instead of 69 and... all debricked just fine !!!
I never found this info anywhere... so i hope could be useful for somebody.
As "recovery image" i used the "openwrt-19.07.0-rc1-ar71xx-generic-archer-c60-v2-squashfs-factory.bin" renamed as "tp_recovery.bin"
Maybe "port 22" could work also for other TP-Link routers.
