I'm newbie and trying to learn about OpenWrt-project. First I want to test OpenWrt on my old router (AVM FRITZ!Box 7330), which I do not use anymore. The page says that it supports version 19.07.1, but I can't find any install image on it. Only OpenWrt Upgrade.
Which image should I install first?
You mean, I can upgrade FritzOS from manufacturer to OpenWrt?
Are the installation steps the same like I would use the install image instead or do I have something to consider?
