All right folks. I have an iPhone on iOS 18.1 and another one on iOS 18.6.1 that can be potentially updated to iOS 18.6.2
My knowledge has it’s limits, especially when it comes to using the terminal and its commands, but I’m not completely dumb, as I sometimes use it (last time I did, using the ping feature to check packet loss on a local network) after copying the commands properly.
With my Mac (on macOS 12.7.6) and a USB to Lightning cable, and your help if you’re interested in digging a bit more about this, I can try to follow the steps and replicate the behaviour on each of the versions. If it’s not too complicated, that’s it.
