I'm in big trouble...

I was on Cyanogenmod 10.2 for a long time, but yesterday I choose to upgrade to CM 11. I did a backup in case thing went wrong and did the update. And it did.
After update I've started my phone and I had no service/reception. So I went to restore my backup. I did this a few times so I was pretty safe about it. When I've tried to restore my backup, didn't work. The restore file didn't do anything but it clear the access to CM 11.
After that started a lot of research on the web for solutions.
I already tried to flash the firmware to stock, using the firmware from Sammobile. Now I get the no IMEI error.
I can't find any EFS folder or backup folder. I can only find the EFS folder but it's empty. I've used the Root Explorer to try and find this folder, but can't find it.
I already read some topics about the same problem but I can't find any solution that work for me.

Can you please help me?
Thanks
