null imei i9505

hello
i have null imei on my galaxy s4 i9505
how i fix this ?
thanks
Perform a search on EFS, EFS backup and restore on S4, and how to restore if you have the EFS backup already. If not, I guess service center is the proper way to go.

Efs

Is the efs swappable between devices? Say my friend back ups his efs. can i then restore his backup if we both have the vs980?
No, efs is unique to each device.

HELP! Null/Lost IMEI after flashing CyanogenMod.

Looking for EFS folder of G360HU for restoring my phone. Or help me to restore my IMEI.

IMEI=0 after restoring external backup

Hello, a friend had IMEI 0 and restored the efs and persist backup from another device and now he can't restore his IMEI, even after flashing lastest pie stock.
Any ideas?
Congratulations!! Flashing another persist and efs backup is the safest way to loose your IMEI.
If there's no backup of it's own (and I guess there isn't) he won't be able to restore his IMEI.
The /persist partition holds a little binary which is unique for each device. It's impossible to recreate it.
