Flash your official firmware by downloading it from sampro.pl or sammobile.com, flash it with PC Odin under PDA tab.
After you done, don't let reboot your phone, goto recovery by pressing vol up+ menu key then power key(continuously hold it until your phone restarts, might be 4~8 secs.) Then check 'Wipe Cache Partition', and then reboot phone.

You've EFS backup as you said above, restore efs separately from recovery (Use Philz touch) in which you've to choose 'Custom Job' to restore EFS Contents. Then flash any rom you wanted to and then just wipe the cache partition, wipe Dalvik cache and you're done.

And if above method won't work give a try with Mobile Odin Pro follow procedure which I've posted above.
Here is your official version: http://www.sammobile.com/firmwares/3/?download=25809

Nope... You've to flash a specific (your area/country) firmware to make your modem work. Otherwise you'll not get IMEI back. You've made a EFS backup, right?

Restore your EFS first, then flash any AOSP, CM based rom. At end wipe cache partition and Dalvik cache. Then reboot phone, wait don't setup your phone yet, again reboot your phone into recovery mode and then again clear cache and Dalvik cache and then reboot.
Use Philz Touch recovery, first must do 'Wipe data >> Clean to install a new rom'. I recommend you to use AOSB rom.

there's nothing you can do now. You have to use z3x or any other similar box to get ur imei back (rebuild nvdata). Even after having the correct IMEI you won't be able to make calls/texts/data (not registered on network error). The modem also needs to be patched by the box. If u don't have a box then take it to a phone repair shop. they'll fix it...but it's not permanent...the next time u flash a ROM you'll lose everything and take it to the shop again. EFS restore brings back the IMEI but the modem needs to be patched everytime u flash.

Hey @driqbd, I got the z3x box from someone, (Abid from Jeddah, Saudi Arabia, official z3x seller) what should I do now? Is there any tutorial in YouTube that can help me to fix the problem?
