Hi, I bought a 2nd hand C7 V2 hoping to install pcwrt lite and checking it out before going premium. But I can’t get it to install, and any help would be much appreciated. I tried the webgui and I get an error of 18005. So I’ve tried TFTP on my Mac using the Transfer app from https://www.intuitibits.com/products/transfer/, which works when I’ve configured a manual IP 192.168.0.66 and it transfers and the router restarts, but it’s still the tplink firmware. Any ideas
