I have tried Framaroot, Universal Android Root, IRoot, Z4Root, TowelRoot and obviously, kingroot. I also attempted to try chainfire's auto root but could not find a compatible file to flash for my device. Here's the link to chainfire's list of compatible devices Chainfire Auto Root
Here is the screenshot of my device software info
You should try rooting with TWRP.
Download TWRP Odin flashable here
Download Odin here
Boot in download mode with POWER + HOME + VOL DOWN
Connect the phone
Flash with Odin 3.10.7. Select the downloaded file using the AP slot. Uncheck Auto-reboot.
Reboot to recovery immediately after flashing using POWER + HOME + VOL DOWN, as soon as the screen goes blank change to VOL UP whilst still holding the other buttons.
TWRP should now boot
Flash the file below in twrp.Â
DO NOT LET TWRP ROOT YOUR DEVICE WHEN IT ASKS FOR. USE ONLY THE FILE BELOW:
Root Chainfire SU
NOTE 1: FLASHING CUSTOM STUFFS VOIDS YOUR WARRANTY. AND THIS WILL TRIP THE KNOX FLAG.
NOTE 2: ENABLE OEM UNLOCK FIRST OR YOU MAY ENCOUNTER 'BLOCKED BY FRP LOCK' WHEN FLASHING.Â
Settings > Developer Options > OEM Unlocking
