Well something went really wrong and i have a corrupt IMEI/EFS partition.
so i followed this and this threads to restore my EFS partition.
But for some reason, my IMEI number / EFS partition is not being restored. Also my mobile network (not able to make and receive calls/ no mobile data) is not working.
Please help ASAP My N7100 is still under warranty but i tripped the knox counter.
Also i am able to go into bootloader mode but odin is not recognizing the device. I installed kies and it is updated.
edit - flashed official stock rom via mobile odin so that i can take it to samsung service centre. But as a last resort, still searching for methods to restore efs.
If anybody still has any suggestions or help, please please comment here.
Thank you vry much,..

i tried this tool but its not working..
the tool shows that there is some data transfer, but nothing is happening in my phone.
just to confirm..how much is the size of a properly working efs.img file ?
mine is around 20,048 Kb
It's 20 mb the image, besides I doubt that you can do anything without a XwZ BOX,which will cost you over $100 so my advice is that you take it to a dealer for a repair , that's if you don't have an EFS back up, however I'm not sure if the things are easier if you have a back up either, since it didn't work for me.

Just a question... How did you make the efs backup you have? Size should be correct
If you remember how did you make backup, it'd be easier...
Have you got just a backup? The file you're using could be a corrupted file...

Yes the dealers can fix it, will cost somewhere between $30 To $40,at least that's the way the things are where I live. That is why I'm gonna keep my Note II on 4.1.2 until it dies away and will get THIS biggi and forget about Samsung alltogether,I have learned my lesson the hard way..

I claimed the warranty..service centre guys fixed it for free.
They replaced the motherboard..costs around 9000 rupees in india without warranty
And guess wat ! They even reset my knox counter
My note 2 is now like a brand new device.
But thanks a lot guys; for all the help u provided in this thread...appreciated .

my note 2 was dead on Samsung logo after i have update your zip it open but every one should be a wear cuz it is a Dummy version any one should not use it if he don't have a efs backup to restore
Hey Guys!
Firstly, I know this same thread has been made for other devices. Most of which have solutions, but these do not work for me. I really need your help with my problem!
The Problem: My GN3 has lost its IMEI, the EFS folder might have gotten corrupt somehow. But by a stroke of bad luck, the IMEI turned to unknown and no methods seem to solve this.
Thus far I have tried changing the IMEI with NV Tools and EFS Pro. None of which work, I tried generating a new file and flashing it on, that did also not help.
It was stock 4.4.2 Samsung, rooted. We sent it in to a service center, but since Knox now says 0x1 they want to charge us R3500 (~$300) to repair it.
Upon inspection, I noticed from my EFS folder that all files starting with 'nv' was gone. SO I copied these from my rooted Note 2 and placed them in the folder. Idea being that I could just change the IMEI using NV Tools, as it didn't work otherwise. This however did not work.
The only sollution I can think of, would be for someone to make a backup (using TWRP or CWM) of their EFS folder, then for me to restore it and then change the IMEI with NV Tools.
I promise I did not steal this phone, and it is not blacklisted or anything. Ill send any who might help me a picture of the IMEI on the back of the phone + the original box and the receipt if they doubt me.
I DON'T WANT YOUR IMEI NUMBER, but I need a full Note 3 EFS folder with the original files, so I can attempt to fix mine.
If anyone has a different solution I'm all ears, and up for anything.

I have done that, all it has done is increase the flash counter from 1 to 2. And remove my root. The EFS is broken (somehow) and I can't figure out how to fix it....

Ok, what I found out as a solution was to delete EFS folder. Android will rebuild it! BUT: My EFS and Baseband are still gone. I reflashed stock (again) using Odin. No Dice. My NV_DATA, NV_CORE ect files are gone!
And IMEI isnt coming back.
If anyone has a spare EFS backup, or a script or something that i can flash to make my device have those files again I would appreciate it very much.

The following might be uotdated but no harm to try anyway(Can't copy the link so i copied everything)
1. Install Stock firmware via Odin, then re-run auto-root (to regain root of course)*
2. Install TWRP 2.6.3.2 via odin, reboot to recovery.
3. Do an "adb shell" when phone is in recovery mode to run commands via TWRP.
From the ADB shell: Wiped the EFS partition with the following command:
mke2fs /dev/block/mmcblk0p12*
mkdir /efs
mount -t ext4 /dev/block/mmcblk0p12 /efs
(the last two commands probably did nothing, but thats what I did anyway)
Do a factory reset, reboot system

I honestly can't remember, I think I just flashed TWRP and wiped the partitions he said to wipe. Then did the reboot.

The rest are quite straight forward
so updated from 4.2.2 to 4.4.2 to 4.4.4 to 5.0.
I didnt check each step, but I have no network access now. I get the circle with the line through it. The phone works perfectly, but no access. EMEI is there, etc etc
I've searched for hours and found no solutions.
ive odined back 4.4.2 but cant get back to 4.2.2
current baseband is I337UCUFNB1
any help would be super super appreciated.
thanks in advance
so I've got a network signal card until I put the sim in.
IMEI, # - everything shows up in the right place. Just no signals available.
No networks showing available.
Anyone??
Check your apn settings. Make sure they're correct for your carrier.

I think this phone is now dead. I need to repair NV, but have no way to do it unfortunately
essentially the phone gets the circle with line thru it. flashed every modem under the sun. not an apn problem. Phone just can see different networks for some reason
problem is NV files, but there is no way to correct issue I dont believe

I feel for you OP, I accidentally deleted my ESF 1/2/3 via service menu (I made a back up via service menu but don't think all the files are there.) A lot of things in my settings are set to "unknown" now. If you find a fix please share it with me, I'm hesitant to try anything else on my S4 since I've already managed to mess it up, but at the same time I guess there isn't much else to lose.

I bought this phone for $50, so even if I can't fix it I'm not out that much money. I'm looking into EFS tool, but since I don't have a back up, I don't think I can restore it.
anyone with efs professional willing to backup your nv file and send it to me??
could try and write over mine and see if fixes signal

Hello guys, I need a lot of help was messing on the Internet from my Galaxy S5 G900M when he crashed and got warm,
I removed the battery called him but was no carrier signal after prsquisar discovered that my EFS is missing files:
.nv_core. bin
.nv_core.md5
.nv_data.bin
.nv_data.md5
.nv_state
I have little money when then pay for repairs to the box is in final plan at the time,
I researched many posts with repair attempts here Forums new and others over the Internet to 3 full days without success, what do you think is like me rebuild these 5 files on my device?
vi whose other older models (Galaxy S4) with a program, only it does not support my model!
Obs:
My S5 was before the problem with the Rom xXx No Limits 5.7 + Boeffla kernel + Root
I've tried to go back to several versions of the stock roms and did not work!
Thank you guys
I also have the same problem with my G900M
It would be very good for someone we help.
My friend, any progress tell me.
i dont want to bother or anythin, but for u to recover the efs file is more or less impossible.... the only way would be if u would have made a efs partition backup trough twrp, since i bet u didnt made one, ur phone is now more or less just a tablet with no usable phone stuff
Hope this helps! Best of luck

I have SM-G900F and in efs partition I don't have this files above too, but i have IMEI in phone and it works good. I think the Galaxy S5 have a special version of efs partition. I can send you my dump of efs part. (efs.bin file, maked by dd in adb in console on PC ) if you want. You can send me your dump of efs to compare this. It is surprise for me why I dont have the folder "sec_efs" like you.

Hi there. I tries to restore my efs backup after flashing stock ROM,but didn't knew the backup itself was corrupt and my phone has no network, no imei and unknown baseband.
Google will not admit this but there were major security flaws in factory images before jan,2017.
Read for yourself below article.
Link: https://www.google.com/amp/www.tech...d-nexus-6-patch-fixes-modem-vulnerability.htm
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...

Really?? Thats a big news for me its no problem do i know him or not.. How can you use someone else EFS/IMEI.. it would be 2 phones with same IMEI number..maybe it will work, but its like you use someone else ID card and present it like its yours..

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
