HowTo: PINEBOOK Pro with Debian GNU/Linux 10 or Devuan GNU+Linux 3 using mainline kernel and u-boot

I have written this guide to outline how I finally managed to get the official version of Devuan GNU+Linux 3 or Debian GNU/Linux 10 installed on a PINEBOOK Pro. It shows how to achieve this using official mainline u-boot and kernel from upstream (no unofficial patches) and without using third-party repositories. However, it does use self-compiled (unpackaged) versions of u-boot and kernel as tweaking their default build configuration files is currently still required.

Installing Devuan GNU+Linux or Debian GNU/Linux on ARM64-based SbCs that are not officially supported

If you want to self-host stuff at home using an ARM64-based board running Linux, both Debian GNU/Linux and Devuan GNU+Linux are excellent distribution choices.

How a single unprivileged app can brick the whole Android system

This article is highly subjective and only states the author's opinion based on actual observations and “wild” assumptions. Unlike stated in the title, it might apply only to LineageOS and not to the original AOSP. Better explanations and corrections are warmly welcome! Motivation After updating an App from the F-Droid store (OpenCamera), my Android device was completely unusable. In this state, the only feasible option for a typical end-user to recover the device (who does not know how to get to safe mode in order to remove or downgrade the app [5]) would have been to wipe data in recovery, loosing all data.
