Hi, do you know how to repair this problem?
I tried to search anything that could help me, I founded Z3X samsung toolbox to repair IMEI, tried to flash stock firmware, tried flash separate modem.bin none of these solutions helped.
Problem started when I install LineageOS 15.1 from stock firmware A310FXXU4CRG2
I tried Factory Binary ROM and repair IMEI with Z3X SW, but it told me that I have unsupported EFS and it cannot detect modem on this phone.
If you have any idea to fix this, please let me now.
(I'm new on forum, sorry if I missed something)

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!

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"?
Hello guys
my problem started when I tried to upgrade from 4.4.2 (KitKat) to 5.0.1 (lollipop), I tried first to upgrade using Kies but I just didn't work it recognized my phone and downloaded the firmware but couldn't install, so I went to the other option "odin" I flashed the firmware for my region for my phone yet when it turned on I had a very week signal.
when I tried going back to kitkat I had no service at all and lost my IMEI and baseband, then I tried different regions of lollipop and kitkat, but still nothing, and I thought I lost my IMEI and that I need to write it manually using this box (I don't remember its name) until yesterday when I flashed a Turkish kitkat which restored my IMEI and baseband but still no service, then I backed up my efs folder and went on trying every modem in this thread http://forum.xda-developers.com/showthread.php?t=2192025
I tried everyone of them some gave me "no service" others "emergency calls only" and a third group didn't even recognize the sim card however all of them changed my IMEI to either NULL or the fake IMEI.
now I tried to restore my esf folder but it didn't work, so I thought to re-flash the Turkish firmware (which retrieved my IMEI and serial) but also didn't work and now I still have a fake IMEI which is weird because it worked before.
I tried every method every solution and nothing worked
I even contacted Samsung who told me that it cannot be fixed in Europe cause it is an international model and has to be fixed from where it was bought (Jordan)
and now um feeling really hopeless
please help

GT-I9500 - Corrupt EFS Folder, wrong number
Hi guys,
I have the GT-I9500 (South Africa) with the following:
PDA: I9500XXUAMDK
Phone: I9500XXUAMDK
CSC: I9500OJVAMDK
My problem started after I mistakenly flashed a custom rom (using Odin) which was not intended for the model GT-I9500, but rather for model GT-I9505, after that I realized that my IMEI number had changed from the correct one to (004999010640000). Since then, I have tried a whole lot of different approaches to try and get this resolved (Flashed official ROM, tried QPST, e.t.c...) I am still sitting with this problem, and in the process of me trying to resolve this, i fear I may have corrupted my EFS folder and well.
Can anyone please help me try and resolve this problem and restore my correct IMEI number to my phone.

I wiped my efs by accident, if you have a backup of your efs or a nandroid backup (can extract efs from nandroid backup) restore it. I didnt so i swapped my motherboard out, lucky i had a spare s4 with a broke screen to get one out of. Good luck

I never heard of anyone who lost their IMEI after they flashed a custom rom. Not even if they flashed a custom rom for another device.
You flashed a 4.2.2. firmware. That's probably the reason of the incorrect EFS. Flash latest Lollipop stock rom.
If you still don't have your normal IMEI back then it is caused by the things you did trying to "fix" it certainly not by the wrong custom rom.

It happend with me. i try changing imri with z3x samsung tool but didnt work for me...nd I dnt have efs backup..I also flash many firmware of kitkat,lollipop,jealybean, and also modems but its wont help me....
Try this thread http://forum.xda-developers.com/galaxy-s4/help/imei-null-fixed-t3008035?nocache=1
I try so many solutions but failed, i thought i had to spent a lot òf money for restoring lost imei. After reading that thread and follow the instrucstion, everything is working fine and i did not spend any money at all.
My experience: Firstly, downgrade your i9500 to andoid 4.4 (should be 4.4 Samsung Stock Rom) and then flash the attached file via odin. Done!

Flashing a custom rom does nothing with your efs. It can't even touch it because the efs is in a different partition. If you can't even fix it with a z3x box, then it's probably hardware damage unrelated to the flashing.

Hello everyone, recently I've flashed the Superman ROM V.3.0.1 and everything was fine until I went to general settings on my phone and saw my IMEI is now UNKNOWN. I know this thread may be already solved, and yes, these days I was looking for answers for my problem but I need to know for sure what alternatives I have to recover my IMEI. I have to mention, my phone is 100% original, it has its own IMEI from the beginning, not a copy or MTK device. I saw some sollutions based on some kind of programs to restore manually the IMEI with a command, and this method for me it's not like the best thing to do in this situation..
When I am dialing *#06# I receive the following information: " SM-G935F is not supported on showIMEI ".
I've checked through TWRP ( version 3.1.1.0 ) the partition EFS, is still there ( it has 2mb ). What do you guys think about this? Flashing the stock ROM from sammobile may solve my problem? What alternatives do I have?
Thank you!
