How do I root Android Lollipop developer preview? How can I best root the new Android Lollipop developer preview? Chainfire's original SuperSU binaries don't seem to work:

  There is no SU binary installed, and SuperSU cannot install it. This is a problem!
  
  If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device!
Right now the only officially supported devices for the developer preview are the Nexus 5 &amp; Nexus 7 (2013).

Chainfire has issued updated SuperSU binaries that allow rooting, but the recently updated developer previews seem to have broken this, resulting in the SuperSU binaries not being recognised. 

Fortunately, Chainfire has responded with a quick fix: flashing a custom android kernel.

Simply flash the modified kernel in fastboot then the SuperSU binaries zip and your device should be rooted.

EDIT: Some users have reported issues with the kernel Chainfire provided. Try flashing this one instead.
