I have been trying now for two days to root this tablet w no luck. Between locked bootloader and firmware I can't downgrade all ive gotten was vacant 'not found' files that I flash and run me into a bootloop or stuck on Samsung screen. I have soft bricked twice already using .tar files for other models because I can't find a philz touch or a twrp or a kernel that matched my build and model number so I can downgrade to KitKat and root. I did find stock ROM was able to get back to a recovery boot which was gone altogether. Any help would be much appreciated.
