No need to flash EFS , just write MODEM from stock firmware and patch cert again,to avoid every time Unknown baseband issue,use old z3x ver.,coz new ver. Might have some bugs....

Download Factory Binary File for your model and 5 files firmware from z3x or from other sites.
Start phone in Download mode and install Factory Binary with help of Odin. once it flash complete. the phone will boot into factory binary mode. and will try to restore factory functions.
if it still show message "CP: uknown CP" then flash back to original firmware.

1. Root your Phone
2. Install Root Explorer and grant Super User Access
3. Open EFS folder and delete every thing Except "Factory App and prov_data"
4. Reboot your Phone, if it gives you some error, ignore its normal.
5. Flash Factory Binary firmware again, now it will restore everything to default regarding Modem.

if you can see your IMEI after this, flash your phone with original firmware and enjoy.

hit thanks if it works or for more help PM me.
