Hi, I messed up with my IMEI code and I'm trying to get the original one back. Anyone have an idea please? I found on the internet that it's stored in /efc partition, how to access this partition please?! Thanks !
Some updates:
On others phones, IMEI is located in either efs or persist partition.
On samsung devices a file called nv_data.bin seems to be the one including the IMEI.
Some guides I found: http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 and http://forum.xda-developers.com/showthread.php?t=881162
I still can't find where is the IMEI located on Nokia X devices.
I have a backup of all my partitions using my own guide http://forum.xda-developers.com/nokia-x/general/tutorial-how-to-revive-dead-nokia-x-t3000903 (second post) and searched for my IMEI code using hex editor in all files but I can't find it; maybe it's encrypted or hidden something like that...
When I backup my full internal mmc storage, I can find my IMEI (the one I need to change to my true IMEI). I mounted the img as RW and replaced all the IMEI found with my real IMEI. I flashed again the whole storage using "dd" command; but nothing have changed....
Some questions:
Does Nokia X have efs partition?
What is the persist partition on Nokia X?
Is there an nv_data.bin file on Nokia X? I already searched for that using shell and find command (busybox) and I can't find it.
Please if you have any idea tell me, this will help many many other people facing the same problem ! Thank you !

Good evening, everyone!
I've recently bought SGS IV Mini LTE with broken EFS and nulled IMEI (showing only true IMEISV), being aware of the fact if broken/lost IMEI. Since previous user wasn't caring enough to try to restore his phone and bought another one straight away, I've been able to buy this little slightly programmatically damaged piece of magnificance for a really low ammount of money.
Questions:
Where is EFS/NVData/IMEI located in phone?
How to disable write protection to important root folders like /dev?
Based on my previous adventures with android phones with broken efs'es I thought i could just get an efs backup of another I9195, hex-edit IMEI to my phones IMEI and restore it to my phone, but i ran into several setbacks. Firstly, efs partition doesn't contain IMEI anymore, which made me wonder, how the hell previous user did manage to null the IMEI, moreover taking in consideration the write protection (not sure if term is correct), which manifests itself as original file restorer after phone is restarted. I tried to override this in several ways, like changing premissions using ES File Explorer. Even just pure deleting of files results in no luck at all, files restore after phone restarts. I guess changes were never written in memory. Or there is a service which restores everything from hidden backup folder on start of OS. Also I tried every free tool there's avaiable. EFS Qualcomm tools, NV reader/writer, etc. Also tried to hex-check backup of every avaiable tools efs for IMEI using different search methods(using another S4 Mini LTE for IMEI location), like searching for Hex converted query, no luck. Any suggestions
Anyone?
Hi
I checked on my phone via adb if I had a efs partition, but it seems nothing is under /efs on the phone
Is it possible to create a new efs file if I have the IMEI code and I guess I could find the phone MAC code in my router since I used wifi before I broke my phone.
So, Have
- IMEI code (found it at google dashboard)
- MAC
Possible to create and push a new efs image to the phone? If so how?
Cheers!
No.its not possible to create a new efs image.
Although it is possible to repair imei using uart box method,but I am not sure of that.

And how do I do that? I took a EFS image copy to my computer, and when I do a cat command on that file, I can see that there is allot of things in that file even though I cannot mount the image. I searched it for IMEI and found some occurrences in the file together with allot of microsoft references etc. Would you know how to fix an broken efs.img file?
Cheers
That method utilises a special hardware called octopus box or z3x uart and also a special cable that has micro usb at one end and rj45 at the other that goes to the box.You can try asking from third party repair shop,they should have the hardware.
The efs.img wouldn't mount on a pc.If you have an efs image then why dont you restore imei using that.On pc,acessing efs.img would deem it as a corrupted image file.
Hi All, we are working on unbricking HTC Desire HD and need the partition info and partition backup from a working DHD phone to move forward. If you have a working rooted DHD, you may help us on any of below. Thank you!
1. if you rooted your phone by using gfree, then as this page (http://forum.xda-developers.com/wiki/HTC_Vision) in section '6. Backup and cleanup' it mentions the gfree can backup part7backup-.bin, etc. If you have those backup files, can you please send them to us.
2. with your working phone, you may retrieve the partition info as this post (thanks E:V:A), can you post your partition info output, as well as your carrier name and ROM info. Other info like recovery type/version, HBOOT display (which shows S-ON/OFF, Radio version, etc) and CRC's are also helpful but optional.
3. If you phone's microSD has 2G or more free space, and you has some Linux and ADB knowledge, you can backup the whole internal memory of your phone to a file on SD, then pull the file over to your PC, and upload somewhere and share with us. See This post (thanks TrevE) for details. Please note this type of backup file has all your phone memory including the IMEI number and your user data, so please don't share it in public. You may use a HEX editor to search the backup file for your IMEI number and mask it (I don't know if it is encoded or encrypted somehow). If you can trust me, please upload your backup and PM me the download link.
4. If you are a developer (know python and has Linux or Windows with Python), you may try to run the attached script to pull the partition info and backup partition by partition as this post (thanks darkspr1te) . However, the post and script was not coded and tested for DHD so you may get error and need to edit the script to make it work with DHD.
Thanks for you help!
Anyone??
You wouldnt know when you would arrive in a QHSUSB_DLOAD situation.
I'm not a tech. So if i wrote something wrong, care to correct.
I lost me IMEI of S4(T-Mobile)- It just shows "/06" after dialing *#06#.
So i was just wondering (after checking the "NAND erase" in odin and accidentally deleting my efs folder) if any how i can get the "nv_data.bin" file.
I know most people might be thinking, "Why to give away my own IMEI data to some random stranger.".
Just for a fix, and wandering here and there. I thought i just need the framework of the file.
Found this link

Maybe if someone be kind enough to edit their Backed up "nv_data.bin" and replace their original IMEI with any random numbers from the file using the above method and post it.:angel: I might be able to get my phone to work again.

And if possible please someone share the screenshot of the backed up content of EFS folder.
Please Help. It might be able to help a lot of people.
ThankYou!
Try a clean flash of a stock rom. I have not tested on the SG4 but it has worked on different models. It may rebuild it for you.

Hi all,
My Samsung Galaxy S9 (SM-G960F) shows IMEI “Null”. This prevents it from recognising it has a SIM card.
* Device is rooted. “no verity” blob installed.
* LineageOS installed successfully.
* No partition backups were done; I wasn't aware of “EFS” or anything like that when I started the procedure.
* Using a root filesystem browser, the ‘/efs/’ directory is apparently empty.
I know the correct IMEI (it's printed on the back of the case). How can I record the IMEI into the device so that it knows its own IMEI and uses the SIM card?
Does this require generating an EFS partition (if that's the correct term)?
I have the correct IMEI. How can I write that to the device so the operating system can read it and use it correctly?

Did you solve the problem and how?
This happened to me with one old galaxy s3 phone and at the time, there was no way to fix it. At least not for free. I also downloaded those tools that the service technicians use, I found them illegally and they didn't succeed either. And here, too, no one knew the way. Maybe there's a free way now, I don't know.
