Not a well known device......

Did you back up your EFS folder before flashing a custom rom on it??

You may very well need to flash a stock rom back on the device. Check your firmware here - http://www.sammobile.com/firmwares/2/

Not sure if this is going to help either - https://www.youtube.com/watch?v=Pai4BH3AWq8

Did you try reflashing the stock firmware?

If I am not mistaken, this is one:

This firmware is also the same one that comes up on sammobile. Looks like the only one at the moment.

it worked and i can see my imei and my sim card is working fine now
BUT its tuck on factory mode and my only problem with that is the wifi as if I turn off my phone or try to connect to an other wifi it turns off and doesnt work unless i factory reset :/ tried going to the efs folder to turn off the factory mode but the folder is empty .. and when I go to recovery mode to reset the phone it says FAILED TO MOUNT EFS FOLDER or something like that
