Samsung S5 Neo Wifi slider stuck "Turning on..."

A

AC Question

So as stated in the title yesterday after changing from one sim card to another which requires taking the battery out my Wi-Fi will not turn on. It either shows the slider in the on position but not green like it should be, just faded out and the writing beneath says Wi-Fi turning on... or it is set in the OFF position and still says Wi-Fi turning on....

This is incredibly frustrating as i have :
Turning phone on and off (obviously)
Taking the battery out
Turning on without Sim/SD
Turned on with the previous SIM used
Reset Settings
Factory Reset
Rooted Phone
Downloaded Root explorer and tried deleting/renaming /data/misc/wifi/wpa_supplicant.conf.

I have looked everywhere online and tried every solution i can find and NOTHING has helped.

There must be someone out there with the same issue and hopefully a remedy?
