So I had to replace my old s4 with a new one because my other broke when i dropped it. So with his new one I got set up and then tried the MF9 system update, ( i believe this on is kitkat?) and half way through the install it just says error, then reboots my phone and in 24hours it says I can update to mf9 again. How do I fix this. I have already tried factory reset and there is no custom roms on it.
