Bass Boot Options

Android 16 Lineout. Screenshots and steps on these pages were taken on Bass: Lineout (Lineage 23.2 / Android 16). On Android 14 (Lineage 21.0) the same tools can look different, sit in a different Settings place, or be missing from that image entirely.

Bass Boot Options is the menu on the black GRUB screen before Android starts. It is not an Android app.

What it is for

Aaropa / Bliss-style installs often show only a short list (Android, Recovery, Advanced). Bass can add a fuller list: tablet, desktop, kiosk, and related start modes. You pick one with the keyboard (or timeout uses the last / default entry).

How to use it

  1. Power on (or reboot) and watch for the boot menu. Press a key if the menu would otherwise hide.
  2. Use the arrow keys and Enter.
  3. Choose the mode you want for this boot (names vary by image: Tablet, Desktop, Kiosk, and extras).

If you changed Boot Config and the device misbehaves, pick a known-good entry here, or Recovery if you were instructed to.

You will not see this extra submenu on images that were built without Bass Boot Options.
