Process should be the same as below but take note: in order to fix reboot looping problem, you need to installs the ME6 rom, then the Kernel and do a factory reset or upgrade to ME7 and skip the kernel since the kernel is for ME6 and not for ME7.
you can root ME7 by following this step:
download the following Zip file and extract it,
MediaFire - Online Space for your documents, photos, videos, and music.
flash cofface_I9500_cwm_recovery_en_new.tar using odin, and when the phone reboots copy both files: stupid_root.zip & Superuser2.apk to your internal storage and then reboot to recovery holding vol-up + the home and power buttons, the phone will reboot to CWM, then choose from the menu: install zip from sdcard, and then choose zip from sdcard, and flash stupid_root.zip, when you're done flashing reboot, after booting up go to your device's internal storage and install suppersu2.apk, now your root!

Root Samsung Galaxy S4 SHV-E300L (Korean LG U+)Stock version that came out of the box and NOT ME6 Version
First of all I don't take credit for the Root Materials nor the procedure, I just have balls to try this on my Korean 32GB S4 (SHV-E300L) since there aren't seem to be anyone posting Root method for this version.
Download the Files here: FileSnack | Easy file sharing
Please inform me if link is broken
DISCLAIMER: I am not responsible for damaging your phone by doing this, Root at your own risk
But I Rooted my S4 without any problems with this procedure.
Procedure:
Make sure:
Your At least 80% Battery Remaining
You have Samsung USB Driver for your Samsung Galaxy S4
Enabled debug mode in system settings
Step #1: Download all the necessary files mentioned above and unzip them on a separate folder at convenient location
Step #2: Save the file CWM-SuperSU-v0.099.zip in you external SDcard
Step #3: Put your Samsung Galaxy S4 in download mode by button combination (Volume Down + Home Button + Power Button).
Step #3: Plug-in the USB cable in your device.
Step #4: Launch Odin3 in your computer, connect your device in your PC and Odin3 will automatically detect the connection and will indicate a COM port on the top.
Step #5: Under PDA tab, select Cofface_19500_cwm_recovery_en_new.tar to flash the recovery. Dont touch any other settings and also make sure that Re-Partition is unchecked. Hit the start button to begin the flashing process.
Step #6: Once the flash is complete, the device will restart, after the restart turn off your device again.
Step #7: Reboot the phone into CWM that you recently installed by pressing Volume up + home button.
Step #8: In recovery menu, Choose install zip from SDcard, press power button.
Step #9: Choose zip from external sdcard press power button and look for the CWM-SuperSU-v0.099.zip. Once done, just go back to reboot phone and you'll have SuperSU installed with a rooted device.
Now You can create a backup from the CWM and save it in your External SDcard and try out Custom roms (compatible to SHV-E300L)
UPDATE: THE ABOVE ROOT IS FOR STOCK FIRMWARE THAT CAME WITH S4 SHV-E300L (Not the ME6 Firmware)
If you have updated with Kies and have the ME6 version the above root won't work.

If youhave ME6 Firmware, you can flash the Me6 Kernell via odin, once done do a factory reset of the phone and don't restore from a backup. You can install SuperSU afterwards but basically the kernell itself is already already rooted.
