Heres the story, recently I rooted my AT&T SGH-i935 and it was fine. I tried to install CWM and it didnt work so i figured to unroot. As i did, my wifi no longer works. As in i cannot connect to my home wifi because it always says 'scanning'.
After I while i just flashed the stock firmware 4.4.2 and my phone was as good as new, but the wifi still doesnt work but my mobile data does. After surfing and reflashing i have come to various conclusions:
-my phone is in factory mode as i flashed the stock firmware of 4.4.2 using the links provided by XDA
-I need to turn off factory mode to have wifi capability
-to do so i need my EFS folder
-I have no contents within my EFS folder and i have been trying to find a way to restore it
-I have tried EFS pro but it says it cannot find the mount point
-I have tried various ways to restore EFS and or to mount it
If anyone can provide feedback/advice/anything it is much appreciated. More experienced users I hope you can look after me!!!
