Currently I have installed the firmware for i317M Telcel (MK5) and want to know if it's worth upgrading to the new firmare KitKat (NF1). I have already activated Knox counter, but I read that if I update to the new firmware I can not use custom ROMs or stock that are not based on that firmware.
So worth the full firmware update or do it for custom ROMs and manually update the modem?
