CyanogenMod fans with the Nexus 9 have been deprived of their Lollipop goodness to this point, but no longer — the Nexus 9 is the latest device to receive CyanogenMod 12 nightlies. In case you don’t know, a nightly is a daily snapshot ROM of the latest changes.
It’s to be considered an alpha ROM as it often contains bleeding edge features, fixes and changes that might not stable. That said it’s a good way to get a taste of what’s to come if you absolutely can’t wait for the release candidates or stable releases to reach your device.
You flash it like you would any other ROM (here’s a handy collection of resource links if you’re not sure where to begin), of course, and you do so knowing that you’re responsible for anything that happens as a result. Take heed to that, and should you decide to go through with it the the download links will be waiting right here.
