But this will not work.

Tyed with: openwrt-19.07.6-ath79-generic-tplink_archer-c7-v5-squashfs-factory.bin and

How can I fix this ?

Tyed to downgrade with: Archer C7(EU)_V5 200628.bin but the same Error Invalid file type.


or downgrade, seems fw1.0.11 supports direct flashing through web interface.

Then use the TFTP procedure as described in the link.
