I have a s4 mini , I update it with kies , but wifi don't turn on, wifi not work
Check if you can update it again, if not, you have to download Odin and flash a new ROM, twice if it happens to you again.
yes I need orjinal rom, can you help me ?
Flash anything with ODIN will trip Knox if you have knox.
Do a factory reset after the KIES update and see if it helps.
