To all : please consider that for restarting the device wifi should be off. the activation of wifi should be after you see your sim provider on the screen.
I suggest to flash your rom with wifi fix .
the procedure ;
1-unzip your downloaded Rom zip file to a folder
2- download and copy WiFix_1.2.apk
3-zip the files again
4- flash your Rom with desired zip file.
5- now you have your wifix pre-installed
keep in mind to turn off Wifi before restarting device. and turn it on after seeing the provider name .
HOW EVER SINCE THIS PROCEDURE MAKES WIFI FIX A BUILD IN APP, IF YOU FORGOT TO TURN OFF THE WIFI BEFORE RESTARTING. AFTER BOOTING UP, TURN OFF YOUR WIFI AND SIMPLY CLEAR THE CACHE AND DISABLE AND ENABLE THE WIFI FIX FROM SETTING > APP > ALL . RESTART AND WAIT TILL YOUR DEVICE RECOGNIZE THE SIM PROVIDER AND ENABLE THE WIFI, NOW YOU ARE GOOD TO GO .
I TEST IT and it works great
