Bad Magic Number

Hey! I own an Archer A6 v2 which is identical to the C6 v2. I had the same problem as you, though I flashed it through the web interface.

The core principal is the same: start with the 24.10.0 image and then go down version by version until something gets accepted. I got 24.10.0-rc6 to flash this way.

Or maybe you've set up TFTP incorrectly? Did you connect a network switch?

See this page: https://openwrt.org/toh/tp-link/archer_c6_v2#installation

You wanted to get rid of Openwrt, why are you trying to flash it again ?

How did you un-flash Openwrt, you posted it didn't work for you.

24.20 has currently broken wifi on C6V2, so better start at 23.05.5
