Rooting your Galaxy Note 4 running Marshmallow can seem like a daunting task at first glance but fear not! We've got you covered in this step-by-step guide that will walk you through the process of rooting and installing TWRP on your device.

Before we dive into the nitty-gritty, make sure to check if your Galaxy Note 4 is compatible with our root method. You can find a list of supported devices at the bottom of this post. It's always better safe than sorry when dealing with complex procedures like rooting!

Rooting allows you more control over your device and gives you access to custom ROMs, apps that require root permissions, and much more.

Here are some things you should know before starting:

1) Rooting voids your warranty: Once you've rooted your Note 4, any damage caused by following these instructions will void the manufacturer's or carrier's limited warranty.

2) Make a backup of important data first! This process wipes all apps and settings from /sdcard/ and internal storage. Be sure to back up everything before proceeding.

Now that we're on the same page let's get started!

Step 1: Enable Developer Options

To access these hidden options, go into Settings > About phone> Build number and tap it seven times until you see a message saying 'You are now a developer!'

Next, return to Settings > About device. Scroll down till you find 'Build number' again then long press on it for about 5 seconds until an option called 'Reset all settings' appears below.

Step 2: Enable USB Debugging

Now go back into Settings > Developer options and enable 'USB debugging'.

Also make sure that your phone is connected via a micro-USB cable while following these steps as we'll need to use adb commands later on!

Step 3: Install Android SDK Platform Tools & Fastboot Drivers (Optional)

If you haven't already, download the latest version of the Android SDK for Windows/Mac from here. Once installed, navigate through the folders until you reach 'platform-tools' or simply type 'cd platforms/ tools' in your Command Prompt / Terminal.

Next up is downloading and installing fastboot drivers if they weren't automatically downloaded during installation:

- For Windows users only: Go to this link & extract contents anywhere on PC. Then right click on Computer > Properties (Win7+) or This PC (8+)> Device Manager> Portable Devices/Other devices until you see your device under 'Android Composite ADB Interface'. Double-click it, then select 'Update driver' followed by browsing for the extracted fastboot folder.

Step 4: Flash TWRP Recovery

Now that we have all necessary tools set up let's flash TWRBoot recovery onto our Note 4!

1. Download SuperSU zip file from here and transfer both files (Twrp.img & Supersu.zip) to your device’s SDcard or internal storage.

2. Boot into fastboot mode by holding down Volume Down + Power button while powering on.

Once you see a screen with an Android robot, press volume up once then connect your phone via USB cable again using OTG adapter if needed:

```

adb devices

```

If everything is working properly, you should now see your device listed under 'device' section!

Step 5: Install TWRP Recovery

Now that we've got our Note 4 in fastboot mode and connected over USB, it's time to flash TWRP recovery onto the device!

```

fastboot boot twrp.img

```

This may take a few seconds depending on your computer’s speed so be patient! When you see the TWRP Recovery screen come up press 'OK' then select 'English' as language before proceeding further down below...

Step 6: Flash SuperSU & Re-root

Now that we've got our Note 4 rooted with TWRP recovery installed, let's flash SuperSU and re-root it!

1. Go back into recovery mode by pressing the power button for about 5 seconds until you see a menu appear.

2. Select 'Recovery Mode' from there then navigate down to 'Install > Install Image...' at bottom right corner of screen:

```

adb sideload /path/to/supervi6-6.0-20150601-TAR.md5

```

This will flash SuperSU onto your device! Once finished, simply reboot into normal mode by tapping the power button once then wait for everything to load up again.

Congratulations - you've successfully rooted and installed TWRP on your Galaxy Note 4 running Marshmallow!
