The current iteration of CF-Root for the Galaxy Note 2 has been named CF-Auto-Root and comes with some key caveats along with the typical installation notes:
The previous root methods via recovery broke the CACHE partition, causing issues with Triangle Away and Mobile ODIN. This release of CF-Root is preliminary to resolve these issues.
This is a one-flash-root thing which automatically installs root, then returns your device to the stock recovery. This is required for OTAs and some DRM-style apps
Installation and usage
Flash the CF-Auto-Root package as PDA in ODIN (details on how to do that are in next post), and your device should reboot into a modified recovery (signified by a large red Android logo) and it will install SuperSU for you and restore the stock recovery, and reboot back into Android.If you don’t get to the red Android logo, boot into recovery manually (“adb reboot recovery”, or boot while holding Power+VolUp+Home).Using this root increases your flash counter. You should run Triangle Away (see below) after rooting to reset the counter. Note that if you want to run custom kernels or custom recoveries, your flash counter will be set to 1 at every boot. Either configure Triangle Away to reset the counter at every boot (Play version only) or only reset the counter when you need to go into warranty.
