[Q][Help]EFS lost! Please help me!

Hi everybody.
I've Installed some days ago a custom rom.
Everything is working fine, but I've seen that my IMEI is changed with generic 00499901064000
even MAC ADRESS is not availlable.
But it seems that everyting is working fine.
Now, I don't rember if I've a EFS backup.
There is a way to rebuild or recover it? (either with that without EFS backup. (I've cell box with IMEI shown)
I've seen that I've a taz file of EFS backup in my SD folder, but it is only 85 byte large.
Thank you very much for help me.
