FAQ

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

First of all do not flash any supersu/superuser/superman zip package to get root. Go to Settings>Developement Settings>Root acces > Apps Only

Are these gapps <insert random gapps package here> working with cm12.1?

Use the suggested package

Why today I got no nightly?

There were a build error or it means there's something wrong with the rom and I've choosen to stop nightlies until the problem gets fixed

Why is TDB not working / supported?

Official CyanogenMod support requies Encryption support. With TDB we can't have an encrypted userdata partition, otherwhise one system will be able to use it and the other won't

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 channel.

Why no <insert miui feature here>?

Because this is CyanogenMod

Will you add <insert awesome feature here>?

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