The wifi button is greyed out on my Samsung galaxy S3

[AC Question]

My samsung galaxy S3 won't connect to my wifi. It's just greyed out and keeps saying "turning on" I've tried factory resetting it and erasing everything and even after the factory reset it's still greyed out.

Sounds like a hardware failure if a factory reset didn't help. Did you factory reset it in recovery mode? You might try going into recovery and wipe/delete the cache partition, and then factory resetting the phone again. Not sure if it'll help though.
