Have you tried flashing stock?

Not yet. I will get it done now. Will report any results

Flashing stock doesn't help. I have flashed the N9005DXUGNH1 firmware, both the imei and baseband remain unknown.
Now I'm using the mokee rom

Uhm. NO. Samsung does not blacklist any IMEI's just because we are rooting/flashing our handsets.
A blacklisted IMEI will not be null/null, a blacklisted IMEI will be the original IMEI.
This is some kind of software fault (Or ofcause HW)
Try to reboot into recovery, do you get failed to mount /EFS?
Best regards

That instruction is for T-Mobile Note 3.
On Note 3 International version the partitions may be different, so doing that may mess up with partitions and may brick the device.
Be careful.

Yes, but the EFS partition may be different.
In that instruction, I see the EFS partition is mmcblk0p12.
But on my Note 3 N9005, the EFS partition is mmcblk0p11.
So just a warning.

I believe that updating from 4.3 to 4.4.2 will not change the partition structure.
The partition structure is device-dependence, and vary from model to model (N900T vs N9005).
@ OP: you can follow that instruction, but you may need to replace its efs partition (mmcblk0p12) to your efs partition (mmcblk0p11, if your device is N9005 international version, as mine).

4.3 Bootloaders can't boot KK ROMs, which is how I came to that conclusion - and vice versa.

Need Help! Unknown Baseband, Null Imei

Hey guys,
So I am a beginner here, had no idea what I was doing and somehow I ended up messing up/bricking my S4. Long story short, after several days of messing around with it, I was finally able to take firmware through ODIN back to stock.
The issue is: The phone still does not recognize my sim card, when I check baseband it says Unknown, and IMEI is Null/Null. After further research, it seems that this has something to do with EFS. Unfortunately, I did not back up any such files since I have no real idea what I am doing.
Can anyone help me out with this? Galaxy S4- SGH-I337, NB1.
I just need the most simple fix to get phone working again.
Thanks.

Get a s4 from a friend and make a back up of the EFS. That's how I have heard people make it work

Maybe this can help you.

The only issue with that is they want me to back up and restore the EFS. I did not back up my EFS initially so I feel it is too late for that.

This may be hard, But if I did find an EFS for I337 online.. How would I go about putting this on my phone?

With EFS restorer Express

I thought each phone's efs were unique to that phone?

Did you ever make a nandroid backup at all? I know twrp backs up the efs hopefully you have that somewhere.
There is an app in the playstore that will give you your efs info using other info. It's called meid converter. Good luck.

It will tell you your imei, and other info that you might be missing. From there you will have to try and figure out a way to reinput them manually. There was an app called anycut that worked great for things like this back in the gingerbread days. I'm sure there are ways to do it in terminal emulater now hopefully a more knowledgeable user can help out with that part.

Still cant figure out what I should do here. Any further ideas?

I have tried changing the firmware via Odin several times, and I am still having the same issue! Can someone please instruct on how to get the baseband and IMEI back if it was never backed up in the first place.
Thanks!!

[Q] [i9505] Galaxy S4 Baseband and IMEI: Unkown

Hi,
I've been having problems with my 4 month old GS4 lately, mainly because I was not able to make or receive calls and texts. I looked up my problem, and eventually traced it down to a unknown baseband and IMEI problem. Sure enough, my baseband and IMEI was missing. I researched and found out that you need to backup your EFS folder as it may have been corrupted, unfortunately I was not able to do so. I even tried factory resetting my phone to stock TouchWiz, hearing reports that a hard reset can fix the problem; unfortunately, I'm still missing my IMEI and Baseband. All help is appreciated
This Phone was/is rooted, and has been flashed several times with custom ROMS.
Thank you in advance.

If the problem started without you flashing or doing anything else, then you have a hardware failure. Your emmc chip is probably broken. Bring it to a service center.

I'm not so sure really. I flashed Cyanogenmod and it was working fine, I could make and receive calls. However, my SIM card died and I had to replace it. That was when I noticed the problem.
EDIT: Okay, I failed to read completely. I kept reflashing nandroid backups however, after experiencing problems unrelated to this.

It might be, since my efs folder have nv_data.bin but i can't tell for sure since i'm still a newbie here.
Did you try searching for efs backup on the phone? I know some roms do automatic backup after flash so it might be left there somewhere.

I can't say for sure. My IMEI and Baseband was visible when I was running CM11. My SIM died eventually, so I had 0 service after that for about a week. During this time, I flashed AntaresOne's Unofficial cm12 5.0. Maybe it was corrupted when I flashed it? Anyway, My efs folder appears to be missing files aswell. I can't seem to find nv_data.bin perhaps my efs folder really is corrupted?

[Q] IMEI null/null, No SIM card - unable to find fix

Hey, I started flashing custom ROMs to my S4 (GT-i9506) about three months ago and everything was okay, but just recently I tried to return to my stock i9506 4.4.2 ROM and i succeeded in doing so, but afterwards I noticed that my S4 wasn't recognising my SIM.
At first I assumed it was a faulty SIM card (my SIM had multiple scratches on it), so I bought a new SIM card and yet the problem persisted. I tried to make calls and etc but my phone retuned an error stating, "Mobile network not available". I decided to check my settings and I noticed that my Baseband Version was labelled as "unkown".
After seeing this I searched for solutions online and came upon S4 service codes, I used the "*#06#" code and it returned a message saying "IMEI... null/null". Yet again I searched for a solution and came upon none to help me
I soon found out that my problem had something to do with the EFS parition in my phone. I re-rooted and installed ES File Explorer and opened up my EFS folder. In her everything looked ordinary, but then I noticed that my .nv_data file was missing, which, if i remember correctly, is responsible for important functions such as the IMEI and Baseband
I tried every solution I could find online and nothing fixed my issue - I'm only writing this as it's the only option which doesn't require me to go to my local Samsung Experience Store.
TL;DR
My GT-i9506 doesn't know its own IMEI and Baseband version and I'm all out of solutions at this point.
Am I better off going to the Samsung Store?

IMEI no longer inhabits the EFS folder, so you're not missing anything. Flash the modem for your ROM again through Odin and see if that corrects the issue. If it does, use Wanam's EFS Backup to properly backup the hidden partitions where the IMEI is now stored.

Flash the latest stock lollipop rom for your device and you will be fine. Sounds to me you were on Lollipop stock and you downgraded to Kitkat.

Tried this too, but failed also

I don't know which of the hidden partitions the IMEI is stored in. I only know where it's not, and that's not in the EFS folder. However, based on the partition names, the IMEI is likely stored in any or all of the following partitions: m9kefs1, m9kefs2, m9kefs3. While unlikely, it could also be stored in the following partitions: modemst1, modemst2.

Hi, I used to use Optimus G, it has IMEI in m9efs* and Modem in modem, modemst*. I never had IMEI problems but on S4 it is really scary. Will backing up EFS in TWRP, manually dd'ing EFS, modemst*, m9kefs* block10 make me stay on safe side?

Just use Wanam's EFS Backup tool. It backs up all those partitions, so no need to run commands in a terminal.

Need EFS Backup of WORKING Nexus 6P

Google will not admit this but there were major security flaws in factory images before jan,2017.

They patched it in Jan. But effected users like us(who got effected on 2016) got proper fu***.
The result : NO SERVICE but detects sim card.
Kindly.....Plz....plz...plz....make a copy of your efs and provide it in this thread. Please also mention what factory image/build number u are using.

No one will give you his EFS backup because its unique for each phone..so you cant use someone else EFS on your phone...

Hey,
When the IMEI is corrupted on the software side, it still shows up using:
fastboot getvar all
So the IMEI is somehow corrupted on the EFS partition. How, I don't know. Seems like the EFS acts like a bridge between hardware/software. Of course, I could be wrong...
Some have tried but didn't succeed. Now, it's not the first time I see someone using another EFS backup and getting his IMEI back. I don't know why it would get "their"" original IMEI instead of the one included in the EFS backup either. But i guess they must all lie saying it fixed their device.
Cheers...

I have restored EFS using a backup from someone else's device EFS. It did not change my original imei.

Down do it. The efs is device dependent. It will contain things like your imei. So even if restored on another device it will end up causing issues due to the same imei on different devices. It can also make it so things like WiFi don't work

Okay thank you, I had no clue about efs so I'll take your word on it.

Guys can anyone share efs so that I can restore and save my phone..I Have no signal ispitevof detection sim card...it shows no service.. But when I use jio it shows full signal..kindly help..

I had similar problem with my OnePlus X. Apparently I was saving and restoring my efs partion with every twrp backup which eventually caused it to become currupt. Thought my phone was toast until a friend on telegram suggested deleting modem1 and modem2 files with adb commands. Sounded more destructive then good but it actually worked sim was reading again and got full use of my phone. It's good to make backup of efs but only once. Not sure if this is the fix for every phone but works with OnePlus and Xiaomi.
How to Fix EFS from Bootloader Mode using Fastboot commands
Setup ADB and Fastboot on your PC.
Enable Developer options & USB debugging on your Android device.
Connect your device to the PC and open a command window on the PC.
Issue the following commands one by one:
adb reboot bootloader
fastboot erase modemst1
fastboot erase modemst2
fastboot reboot
