Hey guys, I was just wondering if anyone knew a method to root a Galaxy S5 on ATT and install a stock KitKat ROM. I can't root it using TowelRoot as it just says my phone is unsupported and I also can't find any stock Roms. Thanks guys!
Unless the S5 has a kitkat rom from Samsung then your closest rom to stock is cyanogen mod.
