No, under absolutely no circumstances should anyone give to you their EFS information/backup. It's illegal for a start. You should have made a backup of your EFS, you're going to have to send it for repair.
^^This, exactly.

Hey Guys I need some help with Nv data (EFS )
The NV data baseband is I9500UBUAMDE nonetheless my firmware baseband is I9500UBUGNJ1
I think this is why my phone do not have a stable conection with cel-towers...
So I need to know, how to update the nv data without corrupt it?
Kindly regards,
AG
Just flash a stock ROM using Odin. This will ensure that the bootloader and modem match.
Already did it some many times... Without results...
The phone is missing the imei and MAC address?
No one is missing...
Phone signal Goes out and in.
However while the phone has signal. I can call and navigate on internet..
Do you need the efs folder?
If the phone has an imei, then it seems like the efs folder may be fine and something else is happening.
So flashes are successful in Odin?
Could the phone be blacklisted? Was it ever dropped? Tried a different SIM card? Tried our SIM card in another phone?
Ok, I have to be honest... I was on 4.4.2
I try to use galaxysim unlock. However EFS was v2 and I restore a v1 efs folder in order to unlock the phone. It works. However after upgrade to 5.0. It start to fluctuate the signal...
Note: v1 and v2 are versions in matter of security of the EFS folder...
That is how this how begins...
Did you restore the original version 2 efs? Do you have a backup of the original efs? If not, I'm not sure if an nvwriter will help.
I think I do not have one...
What should I do?.....
I'm not sure what to suggest. Maybe Google nvwriter and see if it works with your phone.
Yesterday I decided to Upgrade my S4 i9500 to 6.0, the rom is amazing (despite the amount of battery it consumes) but when trying to acces to the imei (*#06#) it shows 0049990106..... as you might notice not my imei, I did this EFS.img backup, via terminal but now I am not able to restore it via terminal, I rooted the phone but I just can't do it. i wonder If i can Write the imei via PC or APK since i have it wrote down in my phone bill but obviously now the warranty is totally void... so I have the efs but I can't restore it (it shows succed restoration but nothing happens, no imei change) and i have the IMEI number and i really need help what can I do?
If it were that simple to change the IMEI, then anyone could just borrow a phone from somebody, get the IMEI, and do some mischief with that IMEI.
Did you restore the imei to a stock ROM?

Take the device to a service center and have them fix it. You backed up the EFS partition, but nv_data, which contains the IMEI, is no longer stored there. Thus the IMEI was not backed up, which is why you can't restore it.
I forgot to take backup of my original EFS and now my IMEI 0 .
I tried some methods to recover IMEI
1) go back to stock rom and take efs backup but there also IMEI is 0 .
2) try to generate IMEI
Etc. Etc.
But I'm failed to recover my IMEI
Anyone knows how to recover IMEI ??
