If you were having troubles with gaining root access on the new Android L preview, struggle no more! Developer Chainfire has just updated SuperSU to work with Android L. He certainly wasn’t hanging around, the preview was only released last week!
If you’re running the L preview, just flash the ZIP through a custom recovery and when you reboot you will have the full power of root access. The update to the app is live in the Play Store now (v 2.01) but you’ll need to flash the ZIP to make sure you have the patched SU binary.
Of course you won’t be able to use Xposed yet as the framework needs updating to work with ART but there are plenty of other root apps which you will now be able to make use of. Go and have some fun!
