Please help , WiFi won't turn on on my m8
I've had this problem 2 remembered times I believe, once when first going to Kitkat on my Jellybean Galaxy S4 and once when I updated my custom ROM to the newest version on my M8. Have you recently flashed a new ROM or update to your phone? If so then the only thing I can recommend you at this immediate moment is to either try re-flashing it or reverting back to what you were previously on. I searched for quite a while on how to solve the "WiFi won't activate or endlessly activates" issue and never did find any solution. Anyways there may actually be a 'better' solution to this but I never found it, if there is then someone else will reply with it.
If that is not the case and your issue lies elsewhere then please further explain your problem and what you did leading up to it to cause it, thanks!
