This took a few hours more than I had hoped, because it's both the first firmware on a new Android version as well as 64-bit. While there have been 64-bit builds of the SuperSU binary for a while now, they were untested until now, and unsurprisingly there were a few (minor) issues to fix before it worked properly.
As such, this root includes SuperSU v2.18, which is a special build for the Nexus 9, which you should definitely not try to put on any other device, nor should you put an older version of SuperSU on the Nexus 9.
I have not yet updated the CF-Auto-Root framework to be able to patch the kernels live (needed on 5.0) or support 64-bit, so this is a more manual root than usual.
It pretty much comes down do:
- enable oem unlocking in Android's developer options
- fastboot oem unlock
- fastboot boot inject.img
- fastboot flash boot patched.img
The included README.TXT is a little bit more extensive, but not by much, and if you don't know what the above does then maybe you shouldn't bother (yet).
Please note that many root apps will have issues with both Android 5.0 as well as 64-bit. There may also be more issues with SuperSU on 64-bit that I have not found yet.
Guess it's time to fix up CFAR and update the new How-To SU with all the 5.0 specifics. That'll all take some time, though.
