F.A.Q.

ROOT! ROOT! Give me root or i'll die!!! Where root is???

Root has been removed from LineageOS builds, to allow people who are not interested in root access to enjoy apps such as PokemonGo or banking apps. A zip to re-enable root will be provided here. Other packages such as SuperSu, magisk or others are not supported and may cause problems

Why no nightly this week?

Build failed. Check again in 7 days

When do I have to wipe data?

You must wipe data only when you're switching from another rom or migrating to Snapshot branch from Nightly and vice versa. You don't need to wipe data when you update in the same release channe (this applies to 13.0 -> 14.1 upgrades too)

Will you add <insert awesome feature here>?

I won't. If you write it, submit a commit to gerrit, where it will be reviewed.

The LineageOS team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!
