Cannot access my router after running sysupgrade

Hi ! Recently I have installed openwrt in my archer c6 using GUI method . then I ssh to my router and transfer update bin file using scp command and when I was running sysupgrade command I accident turnoff my router when it was updating . Now I cannot SSH into my router . how can I proceed further ?

ssh command is returning error No route to host

Sysupgrade or opkg update?

Archer C6s

Sysupgrade ( My bad)

then you'll probably need to do a TFTP recovery.

I should run tftp at right?

depends on your version of the C6, but it appears to be 66 for the v2.

I am trying tftp and capturing packets using wireshark . There is no tftp request from my router
