i have same problem
:crying:

If I were experiencing this, with my limited knowledge, I would flash with Odin back to stock mdc and do a full factory reset. If after that there wasn't any network connection, I'd call Sprint customer service number from a land line and ask them to walk me through programming the phone properly. I'd probably tell them the phone kept freezing up so I did a full factory reset and now the phone refuses to connect on the network. Maybe something unknown happened and something got erased during the reset and needs to be entered manually again. I'm not saying this is what you need to do but I'm saying that this is what I would do if it happened to me. I do not claim to know what I'm talking about either but it sounds like the most logical thing to me to do.

Because we didn't get a full restore for this it may be an issue.
I'll see if I can make a better package to hopefully fix that.

Bump, is there no fix for this yet?

This is why you do a efs back up

Try This
In the meanwhile,
Read this.its for an S2,but the same concept applies.

Solution
Just flash old MDC tar such L720VPUAMDC_L720SPTAMDC_L720VPUAMDC_HOME.tar.md5
You should get signal back
then use DFS Tool to restore MEID & ESN & IMEI if you lost then.

Agreed. Whenever I have imei problems I reflash the modem, when you do this it rebuilds the NV files and such.
If you still feel like you need the Service Mode Menu you may need to navigate to efs/carrier/ and edit the hiddenmenu file with a text editor to ON instead of OFF . If this doesn't work then google the subject and you will find your answers.

Note n9005 imei 0/01

Hi
I updated my Note 3 (N9005) with firmware from SamMobile. Now everything besides calling works, and I have IMEI 0/01.
I don't have EFS back up, is there any way to repair this

You posted in the wrong forum.
Without a EFS backup you are officially screwed. Contact Samsung support center seems the only solution (unless anyone is stupid enough to give you a backup of their EFS partion containing their IMEI code)
Good luck

N9005 EFS Backup
Hi
Would anyone be kind enough to share their Note 3/N9005 EFS backup so that I can try and get my handset working again
I do not have access to a local service centre in my part of the world, and the only option would be to send away which will probably take weeks where I am as I have to send it to another country.
Please help
RajSE

gud luck

Do you have .nvbak file in your Efs folder.?
Have you tried emergency firmware recovery in Samsung Kies?

SN changed
Hi guys i have searched high and low, My N9005's serial number changed after flashing a rom and when i restore a backup up of my EFS it doesnt correct the problem. Is there any way of reinserting the serial number back into my phone in order to get it to start working again?

Have you downgraded recently?
Older modems cannot read the efs folder after you have upgraded th re n downgraded because the format has changed.
Sent from my Galaxy Note 3

Yeah I downgraded but when I read a few threads on here I upgraded to the newest firmware for my handset using odin. Strange things are happening everything else works but it keeps saying emergency calls yet it connected to my carrier to get apn settings and immediately went straight back to emergency calls, plus my serial number in settings are different. I'm totally baffled by it

[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!

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"?

You need to backup efs before doing this type of activity, however you can try chimera tool or z3x box to repair your imei on this exynos version.

@irfanbd94: You should have posted your comments to your thread instead of this one.
Take your phone in for service. Trying to transfer the IMEI of a defunct phone to your working phone is illegal, period. No discussion of how to do it is allowed.
