Default Sprint Tab 3 SM-T217S B8

i am looking for a Rom that truly works on this tablet i have tried a few different ones and they all seam to have there own problems but all of which i have tried share one problem and that is that the screen flickers constantly and i cant stop it not matter what i try i know this is probably a long shot considering i couldn't find any myself but if there is anyone out there that has a Rom that really does work and doesn't flicker or have problems with WIFI please tell me about it so i can get off of this stock Rom that i have. Thank You
