Sorry it not my native langue) its about making screenshoot instead of photo)
sorry for inconvenience, I`ve made this not on my Mac (so I made a photo)
Just copy/paste the text into your post instead of taking screenshots from it please.
The C6 v2 EU only has 8 MiB of flash if the wiki entry is correct. You will not be able (and should not try to) install anything relying on OpenSSL. If OpenVPN can use mbedTLS e.g. you might have more luck. You'll also need to integrate the packages into your image to save space, e.g. with an online image generator, installing them through opkg is less space efficient.
Reason i was trying to upgrade was because original soft was freezing couple times a week. Which was annoying. Can You help me unbrick my device? I'm still able to connect via ssh.
Those are old instructions. Since this model is now included in 22.03, there is no need to use snapshots or install LuCI separately. Use the 22.03.2 image linked on the device page (see Boromini post above for link). Install using sysupgrade -n so it starts with a blank disk and default configuration.
Note that there are two versions of the C6v2 depending on the country of original sale. The EU or RU versions are 8MB but the US version is 16. Be sure to use the proper build for your hardware. The country code is on the bottom label next to the model number.
Ach yes. I didn't realize that the availbe space is huge. Almost as big as floppy disk. I've already wanted to use this router as part of wifi mesh. But since I have availbe 56KB of free space i can't install wpad-mesh-openssl. So This router won't do their job. I'm looking around about archer c7
if you use it as an AP, use the online image builder, to remove all the wan related packages, like firewall, ppp*, dhcp client (if you use static IP) and dnsmasq, to free up space, and (try to) add wpad-mesh-openssl instead.
You are awesome!
