Re: mobile data icon
Is your problem with an icon or the widget. To get back your widget, you should be able to hold down on the main screen and find it there. If this wasn't your case, I don't know the problem.
I'm sure the problem is as basic as just trying to connect to the Wi-Fi by getting the WPS key. Hopefully that should work. I can't think of anything else.
I also feel sorry for you, that you had to reset your phone and lose everything.
So basically, whenever I try to type in my password, the keyboard won't come up. I've already tried safe mode and hard reboot. Are there any other methods beside resetting the phone?
