In the ongoing effort of having root on 6.0 as streamlined and seamless as possible, SuperSU v2.61 BETA was just released.
I've just uploaded v2.70 to the Play Store, which removes the 500px-supported upgrade to allow pinning for 7 days.
I've just uploaded a new version of LiveBoot to the Play store, which should start updating in a matter of hours. Alternatively, you can grab it from the thread on XDA ( http://forum.xda-developers.com/android/apps-games/liveboot-t2976189 ), which is also the place where your questions should go.
I posted some boot images (and basic how-to to make your own) for all the 6.0 Nexuses and a special installer ZIP (TWRP) for SuperSU on XDA.
I have just uploaded a new version of CF.lumen to the Play store, which should start updating in a matter of hours. Alternatively, you can grab the latest version directly from the XDA thread ( http://forum.xda-developers.com/showthread.php?t=2711912 ).
There's a new test version of CF.lumen available at the link in the box below.
I have just uploaded a new version of StickMount to the Play Store. It should be available for download within a few hours. Fixes a number of issues with M.
I just uploaded the new version to Play, should start rolling out in a few others. You can also grab the APK from the XDA thread here: http://forum.xda-developers.com/android/apps-games/placeholder-t3050998
