If you want to have full privileged control over the Android operating system and the freedom to choose what to install and what to uninstall then you need to root the device. Rooting the Samsung Galaxy Tab 4 8.0 SM-T335 can potentially be done a few ways depending on what is available out there. Many devices that have a custom recovery image available can install it and then use the custom recovery partition for doing things like installing SuperSU.
While many people enjoy doing that, not everyone wants to have a custom recovery installed. For all those times there is the CF-Auto-Root for most Samsung devices that come to the rescue—a one-click rooting tool also developed by the same guy behind SuperSU.
- You must have the Samsung Galaxy Tab 4 8.0 tablet that comes with the SM-T335 model number to use this guide.
- You must have a computer running on the Windows operating system to use the Odin flashing tool.
BEFORE WE BEGIN
- Chainfire was running on the KOT49H.T335XXU1ANE1 firmware build number when he created the working rooting method found in this guide. You do not have to be running on the same firmware build number that he was running on when you flash the rooting file. The guide works for everyone running on Android 4.4.2 KitKat so long as you have the SM-T335 model number.
- If you flash the CF-Auto-Root tool found in this guide, and the Samsung Galaxy Tab 4 8.0 does not boot after the flashing you need to let Chainfire know by leaving a message along with the new recovery image from the problematic firmware on the CF-Auto-Root thread made on the XDA-Developers web forum .
- Install the Samsung USB Drivers  on the Windows computer so the flashing tool can understand when the device is connected to the computer.
- You need to unlock the Developer options menu and enable the USB Debugging  on the Samsung Galaxy Tab 4 8.0 SM-T335 tablet before the rooting is possible.

In conclusion, that is how to root Samsung Galaxy Tab 4 8.0 SM-T335 tablets running on the Android 4.4.2 KitKat software updates by flashing a version of Chainfire’s CF-Auto-Root tool that successfully installs and enables the SuperSU so you can install root applications from the Google Play Store and other third-party sources online. The SuperSU is available from the app drawer when the Galaxy Tab reboots, and it is already set up for you to grant the rooting permissions over the root apps that you choose to install. Even if you are planning on removing apps that already exist on the tablet, you can still download more apps to help you with that job. One of root apps that can contribute to removing system apps is the Titanium Backup app which you can find available from Google Play.
