Yes, PinePhone itself is a new device in testing stages and isn't shipped with a default OS yet. I did my research, but it's fair to be precise. Old Maemo is based on Debian. Updated with installation instructions. https://leste.maemo.org/PinePhone#Installation Build instructions are here: https://leste.maemo.org/Image_Builder In other news, the sha256sum on the .xz image doesn't match its corresponding .sha file. Also, it would be helpful if it was named .sha256 so I wouldn't have to guess. The sha256sum on the .tar.gz image does match. And I dd'd the .tar.gz in the usual way, but it did not boot. Neither did untaring it work. What am I doing wrong?
