I had problems with my EFS folder and IMEI.
Now i got it all back and running the Official Android 4.3 Firmware I9300XXUGMK6-DBT
But now i want to go back to custom roms ( Paranoidandroid ).
With the update to EMG4 Android changed the EFS folder.
That was the problem why i lost my IMEI.
What can i do, to get custom roms back !?
Everytime i flash ParanoidAndroid i dont get MobileNetworks.
