I uploaded on my brand new router via tftp the recovery.bin image downloaded from here https://downloads.openwrt.org/snapshots/targets/ramips/mt76x8/openwrt-ramips-mt76x8-tplink_tl-mr6400-v5-squashfs-tftp-recovery.bin
The router boots but there is no wifi. I can connect via ethernet and I get a 192.168.1.x IP assigned by the router. The GUI is not responsive but I can connect via SSH on 192.168.1.1 (root, no pass).
I tried running sysupgrade from SSH, both with the sysupgrade.bin firmware and with the recovery.bin firmware but that does not solve the situation.
I also tried reinstalling the recovery.bin firmware via tftp but the results are the same (no wifi, ethernet, DHCP and SSH working).
Does anyone have any suggestions on how to rescue this partially bricked router and install openwrt successfully?
Thank you.
