The new CM13 Nightly based off of Android 6.0 Marshmallow is now officially compatible with Samsung Galaxy Tab Pro 8.4. It is still quite early for CyanogenMod developers to release any sort of release candidate but in order to show case their work and give users a good test environment, they have released CM13 Nightly builds for a handful of devices. The new CM13 follows the latest Android 6.0 Marshmallow standard which brings some major changes on it’s own. Also, CM has upgraded their own tweaks such as the new Theme Engine. For loyal CM users, if you are currently running official CM12 or CM12.1 than you can easily upgrade without wiping data. Our tutorial given below will list all of the steps required for updating your Samsung Galaxy Tab Pro 8.4 to CM13 Nightly Android 6.0 Marshmallow custom ROM. Not necessary, but it would be better if your tablet is rooted and has a custom recovery installed.

A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat and Marshmallow.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model. And also make sure you have an unlocked bootloader (except Samsung).
