Do not update to Android 13 on 6th generation Pixels before installing - GrapheneOS yet. It will be a couple weeks before GrapheneOS is ported to Android - 13 and you cannot install Android 12 firmware once you've updated to Android 13 - and therefore cannot install an OS still based on Android 12.
+If you have a Pixel 6, Pixel 6 Pro or Pixel 6a updated to Android 13, + you need to install Android 13 GrapheneOS from our Beta channel instead of Android + 12.1 GrapheneOS from the Stable channel. It's not possible to downgrade from + Android 13 firmware to Android 12.1 firmware and the installation script will + report an error. Beta releases are the same kind of production releases as the + Stable channel and installing a Beta release still defaults to receiving updates + via the Stable channel.
