You can become the root user of the Samsung Galaxy Tab 3 SM-T315T tablet when it is running on the Android 4.4.2 KitKat software updates by installing the CF-Auto-Root tool. The CF-Auto-Root installs and enables Chainfire’s SuperSU which is the same version of SuperSU that you normally get when you flash it from a custom recovery image. The hard part is getting it installed. The CF-Auto-Root tool needs to install a modified cache partition and a modified recovery partition which then allows for the enabling of the SuperSU.

Here is everything you need to root the Samsung Galaxy Tab 3 SM-T315T running on the Android 4.4.2 KItKat software updates.

Details We Should Know

  • Chainfire had the JDQ39.T315TDVUAMK5 firmware build number running on the Samsung Galaxy Tab 3 SM-T315T when he created the rooting file found in this guide. You do not have to be running on that same build number at all. As long as you have the Tab 3 that comes with the SM-T315T model number, and it is running Android 4.4.2 KitKat, then this guide should work for you.
  • If you follow the guide, and it does not work it is likely due to there being a new bootloader present in the firmware you are running. These cases are rare in our guides because of a new bootloader usually only comes after updating to newer versions of Android, but they can still happen. You need to let Chainfire know about the issue by leaving a message with the recovery image file from the new firmware on the CF-Auto-Root tool thread made at the XDA-Developers website, and Chainfire can update the file, so it starts working again.

Files We Need

  • Download the CF-Auto-Root tool for the Samsung Galaxy Tab 3 SM-T315T tablet when it is on Android 4.4.2 updates.
