GrapheneOS

Installation

Just follow the official guide at https://grapheneos.org/install/.

If you use the Web installer use a classic installation of your browser instead of flatpaks or the like. Consider also to run it without an external sandbox like firejail.

To enable non-root flashing with a distribution other than Arch Linux/Debian based, you can directly install the source of the android-udev packet from Arch Linux as long as your system isn’t too exotic:

git clone https://github.com/M0Rf30/android-udev-rules.git
cd android-udev-rules

sudo install -Dm0644 51-android.rules /etc/udev/rules.d/51-android.rules
sudo install -Dm0644 android-udev.conf /etc/sysusers.d/android-udev.conf
sudo systemd-sysusers
sudo gpasswd -a "$(whoami)" adbusers
reboot

Settings

• Use a secure PIN (or password).
