My phone wifi won’t activate and I allready firewire it with odin and a factory rest after that, is there anything I can do?

Are you using a custom firmware? If so that could possibly do it. Other than that if it isn’t turning on and you’ve tried a factory reset and you’ve re-flashed the phone then it could possibly be a chip in the phone that either needs re-soldered or replaced. Might be best to have a repair shop look at it. Same goes with the bluetooth. Wifi and bluetooth commonly share a chip inside the phone in Samsung phones.
