I purchased a Samsung s4 i337ucufnc1 in usa. Have the phone unlocked and am now in South Africa. I have tried to root it and think it is but the wifi is not working. Initially the data was not working and wifi was but after I believe rooting and countless factory resets. It has switched the other way data works and wifi says a security setting will not allow updates, the operating software is the 4.3 version.
I have not found many codes for the samsung s4 i337ucufnc1
how do i get the wifi to work again. Please
