Samsung Galaxy Tab 4 8.0Is the allure of becoming a root user tempting you? You are not alone. Many people are becoming root users of the Android operating system each day so that they can run more apps. There are many thousands of apps waiting to be installed on the Google Play Store that cannot run without root access. The root apps can do a variety of things—from changing the way the UI looks on the display, to helping you save more battery by reducing the stress put on the hardware. There are even apps out there that can help you remove the system apps that are running on your Samsung Galaxy Tab 4 tablet already. In addition to browsing the Google Play Store for these root apps, you can also find many other well-known root apps from developer websites—although, you need to be more careful with what you choose to install and where you decide to install it from when downloading from outside of Google Play.

Anyone who wants to change the way the navigation bar on their version of Android looks can try installing the Ultimate Dynamic Navbar. With the Ultimate Dynamic Navbar installed correctly, you can run one of the most magical navigation bars around. It lets you adjust how the navbar is displayed in according to your settings. The settings of the Ultimate Dynamic Navbar even allow you to change things based on what time of day it is running.

Here is everything you need to root Samsung Galaxy Tab 4 8.0 SM-T330NU tablets when they are running on the Android 5.1.1 Lollipop software updates so you can install awesome root apps like the Ultimate Dynamic Navbar:


  • You must have the Samsung Galaxy Tab 4 8.0 with the SM-T330NU model number to use this guide. Flashing the wrong version of the CF-Auto-Root tool for a particular model number means it is going almost always to get bricked. You can find out the model number of the Samsung Galaxy Tab 4 8.0 Android tablets by tapping on the Menu > Settings > About Device > Model Number.
  • You must have a Windows computer to follow this guide because the Odin flashing tool only runs on a Windows environment. It is possible to set up a Windows virtual machine from a Mac or Linux computer if you are desperate.
  • The CF-Auto-Root files can often work for multiple versions of Android, but they can often need updating also. That is why we make our guides based on Android versions. We only recommend following this guide for the Android 5.1.1 Lollipop software updates.


  • Chainfire was running on the LMY47X.T330NUUEU1BOI1 firmware build with the Samsung Galaxy Tab 4 8.0 SM-T330NU tablet when he created the rooting tool (A unique version of CF-Auto-Root) that is available in this guide. You do not need to be running on the same firmware that he was running when he created the rooting file. You can be running on any firmware as long as it is part of the Android 5.1.1 Lollipop version and you are using the Samsung Galaxy Tab 4 8.0 that comes with the SM-T330NU model number.
  • Unlock the Developer Options menu on the Samsung Galaxy Tab 4 8.0 SM-T330NU if you do not have it unlocked already by tapping on the Menu > Settings > About Device. Now look for the Build Number area and tap on it with your finger at least seven times. Do not stop tapping until Android gives a message on the display stating that you are using the device as a developer.
  • Enable the USB Debugging Mode on the Samsung Galaxy Tab 4 8.0 SM-T330NU if it is not enabled already by tapping on the Menu > Settings > Developer Options > USB Debugging.
  • Install the Samsung USB Drivers on the Windows computer for the Samsung Galaxy Tab 4 8.0 before you get started with the guide so the Odin flashing tool can detect your tablet.
  • Some Android updates can bring new bootloaders with them that stop CF-Auto-Root from working temporarily until Chainfire updates the files. These times are rare in our guides because new bootloaders are usually only present when a new version of Android arrives. Nonetheless, if you find your Samsung Galaxy Tab 4 8.0 not booting after flashing CF-Auto-Root it is likely because the file needs updating. Chainfire asks if you can leave the new recovery image found in the new firmware in a message on the CF-Auto-Root tool thread made at the XDA-Developers website for him to see so he can then use it to update the file.


  1. Download the CF-Auto-Root tool for the Samsung Galaxy Tab 4 8.0 SM-T330NU running Android 5.1.1 Lollipop software updates.
  2. Open the Downloads folder on the Windows PC and extract the rooting file to the Downloads folder, so the Odin flashing app and the CF-Auto-Root tool file are both now in the Downloads folder.
  3. Double-click on the Odin flashing tool executable file (.exe) and it opens on the computer.
  4. Boot the Samsung Galaxy Tab 4 8.0 SM-T330NU tablet into the download mode and then connect it to the computer with the USB cable that you use to charge the battery.
  5. Check the Odin flashing tool user interface brings up an added message and the ID: COM port lights up a yellow or blue color. (These two things means that the Samsung USB Drivers are working).
  6. Without changing any of the default settings, click on the AP button and then browse through to the Downloads file where you extracted the rooting file and select the MD 5 file to upload to Odin.
  7. Click the Start button from Odin and the rooting begins.
  8. Wait until Odin returns a green box with a pass message inside it before unplugging from the computer.

In conclusion, that is how to root Samsung Galaxy Tab 4 8.0 SM-T330NU tablets running on the Android 5.1.1 Lollipop software updates by flashing Chainfire’s CF-Auto-Root tool—a one-click rooting tool that is available for most Samsung smartphones and tablets. The CF-Auto-Root tool just automatically flashed the SuperSU on the tablet, so it is installed and enabled and thus allowing you to install the applications that require root access before they can run.

    I’ve installed files using current Odin for my Tab 4 8.0 Wi-fi model and the tablet becomes unusable once complete. Continuous messages of ‘TouchWiz not responding’ along with at least 6 other programs not responding. I can get into Settings from quick menu but cannot get into apps.

    I’ve successfully reinstalled stock for now but still want to root device. Any ideas?
