[Q] Need help to repair my IMEI I5800

I need a help in repair my Samsung Galaxy 3 i5800, I have unlocked it more than a year ago and I have backed up the efs folder before doing it, and it was working perfectly till some days ago.
Suddenly, it doesn't connect to the network and I can't use it any more, so when I checked I have found the the IMEI is composed of zeros only!
So I wanted to restore the nv_data.bin but I have found that it was deleted from my pc!!!!
So currently I don't have the original files, so how can I do it?
Any help is really appreciated.
Thank you all.

Not Register in the Network

Do you see your IMEI number if you type *#06#?
Did you backup your EFS folder? It may have gotten corrupted somehow.

Yes i see it, it starts by "0049.....". It's strange, because my IMEI number in the galaxy S4 box aren't the same. In the box, the IMEI number start by "357....".
For my EFS folder, i don't have a backup :s

Oh dear, your phone has had it. You have a corrupt IMEI number.
This recently happened to my Galaxy S3 (IMEI also changed to 0049...) and after days of various members of XDA trying to help there is NOTHING you can do to fix it if you haven't backed up your EFS folder.
Go back to stock and send it off for repair. Mine is back at Samsung as we speak
Lesson learnt - ALWAYS backup your EFS folder!!!

Gona try it when i arrive home.
My hope is not lost.
Wierd thing is i instaled the stock SM-n9005 rom from my country and it wokred a week later tested on another live demo and he made it turn it on and after a couple of minutes, when searching for wifi networks he just crash and restart.
gona try it and i will tell you

How did u get demo phone in your hands?, was it stolen? i work in a phone shop and there is no way to get them unless you are official retailer plus they dont meant to be connected to cellular network....

IMEI alteration is illegal in most places and not allowed to be discussed in the forums.

[HELP] I9505 has no nv_data in EFS

Hello to all. I'm trying to fix my friend's s4 i9505 because it shows that it's Baseband is Unknown and IMEI is null/null.
He told me the baseband and imei changed when he upgraded to 4.3 using wifi.
I have tried to flash stock rom but unfortunately the phone is in 4.3 so no downgrade.
I have tried flashing different modem.bin but still no avail.
He did not back up his EFS folder before upgrading to 4.3 but I still looked at the folder anyway.
I noticed that inside the EFS folder, there is no nv_data.bin and md5 file which is I think needed for the IMEI.
Is there a free way of recovering these files?
Is this a hardware failure?
I tried the different methods on recovering IMEI in the forums but all of them involves those 2 files so I can't continue.
I have another friend who has a i9500, can I copy and use his nv_data files? (He is willing to do it BTW to help my friend)
FYI: WIFI, Bluetooth and other functions are OK. It's just the call an text function which do not work.
Currently in JB 4.3 XXUEMJ5
No more warranty on the phone.
Any help would be greatly appreciated.
Thank you for taking the time to read our problem.

This phone isn't that old! I have only today contacted Samsung as there is nothing in my EFS folder, they are sending out a jiffy bag for me to send the phone to them to repair under warranty!
Be careful talking about swapping efs partitions from phone to phone as the mods in here get funny about it, I would try contacting Samsung to return it if you can? When did you get it?
I would suggest you do the same. I can't fix mine either.

Should I try this too? I've just seen on Samsung website that mobile phones are covered for 24 months. I've only had this 8 months.
It's weird I have imei number when I type *#06# but nothing in efs folder!
Sent from my GT-I9505 using xda app-developers app

Thanks for all the replies. I tried to check it with my local technicians and all of them told me that my main board needs to be replaced.
I didn't know that a software mishap can result to a hardware failure to the extent of changing the main board.
I have tried flashing the recommended modems above but unfortunately still does not work.
I have noticed that when I type *#1234# in the Phone app, It shows me the AP and CSC and that is all written in the screen. No word modem and no modem version.
When I try to flash a firmware or a modem it says it flashed successfully but when I check the phone, still no service.
Again, wifi, bluetooth and other phone functions are working.
Technicians told me it is a "no service" unit and "cannot be fixed by software" because I have a "broken baseband/modem".
Is there really no hope for this unit?
Again any help or info is welcome.
Thank you for reading friends.

What do you want anyone here to say if you've been told by someone qualified that it needs a motherboard replacement ? In some (many ?) countries, this would be fixable by 're-writing' the IMEI to the device (either by a Samsung service centre or other repairer), but if that's not possible for whatever reason in your country & the way they fix it is a motherboard replacement, you don't really have any other option, do you ?
Edit - Attempting to move EFS files between devices normally ends up in both being blacklisted. Not recommended.

Hello,
I have exactly the same problem, with the i9505 phone version, do i have to change the motherboard or it can be fixed the "soft way"?

Hi. I think you'll get more help if you ask your question in A-Series 2017 forum. There you'll also find TWRP and root for A520.
The files you refer to is probably the nv_data.bin in /efs. I've read it should be possible to restore imei somehow by using hex-editor but I have no experience in that. I also know some older models had a "hidden" menu where you could perform a NV restore but I don't know if it's possible on newer devices.
Anyway, I wish you best of luck to restore your IMEI and hope you'll find someone who can help you more.
