Bootloader should be unlocked . Ensure you are on the correct firmware that is listed above. I have extracted and compressed the file that is needed. It has been tested and working. This should be installed using Odin 3.14.4 and flashed in AP slot. Once you have correct firmware flashed on device, turn off device, open Odin, put device in download mode, add boot.img.tar to AP click start. After flash completes device will be rooted. Setup device install Magisk Manager follow prompts.
WARNING...THIS PROCESS WILL REQUIRE A FACTORY DATA RESET ONCE COMPLETE. MAKE SURE TO SAVE OR BACKUP ALL IMPORTANT FILES.
