There is a root method available for the VRUEMA7 Build that does not require you to wipe your device or flash ROMs, but it does not have an unlocked boot loader (source & credit to: http://forum.xda-developers.com/showthread.php?t=2380325)

STEP 1: Download all three files from the first step from the source above and install/extract as necessary.

STEP 2: Insert a microSD card (exFAT format REQUIRED) into your device and connect it to your computer as a media device.

STEP 3: Move the extracted files and folder from the Root Exploit package onto the root of your microSD card. Do not put them in ANY folder.

STEP 4: Open the Android Terminal Emulator App on your device and run the following commands hitting return after each line:

    cd /mnt/extSdCard
    ./pwn
    ./script.sh

After the second command you should see the '$' change to a '#' indicating root access. The third command will make root access permanent.

STEP 5: After the above commands have run, you can download and open [SuperSU][1] and check for binary updates. At this point you should be done and you can open an app that will request root access to test this.
