I have read we can use tmobile roms, will this still enable me to get signal, wifi etc. Also will it install knox, I ve heard scary stories about that. Can someone lead me in the right direction . pretty please
Tmobile 4.3 roms are your best bet but you'll need to have a custom recovery flashed as well as root. These custom roms dont come with the KNOX bootloader and most have been debloated, so the KNOX apps have been removed as well. Lastly, flashing the Tmobile 4.3 roms shouldn't change your signals or wifi or anything like that, though anything is possibile when you flash a rom.
There are some reliable 4.3 Tmobile roms in the first post of this thread that I have tested myself. You can flash one of these or go to xda and try some of them for yourself.
