hi all
my problem its the classical no nv_data.bin on the /efs section , the one i found its on efs/root/afs/settings but its BLANK nothing on the file i soft brick the phone several times and restored again and again and nothing.
i use the metode using the package T595VUVKF1 and the froyo PDA.KD1 and
are any way to make a full format of the ramdisk to make a fresh install?
i ask this because the section ROOT of the efs NEVER dissapear allways its there.
T-molibe T959v
Did you make any previous back ups on your phone?

Well.... Sorry I suggest searching XDA through GOOGLE and read the other hundred posts and suggested fixes regarding the issue. Try the different methods mentioned. There is one guy 'ODIA' that I have read, and seems to be the only one, who can fix this issue. But you have to pay him, give him access to your computer and the sensitive info on your phone. I tried helping somebody with about a dozen methods and none of them worked for him. But he had a null IMEI (all 0's) and his phone still worked.

One option is to flash to complete stock and take your phone to T-Mobile. Tell them it happened when using Kies mini to upgrade to GB. I read over and over that it has happened to people during that process which would not be your fault and they should help you fix it.
Good Luck!
ty for you time
i didwhat you say and they ask me if i have a phone line whit them ofcourse i dont so they say " just clients can have help from us , and i recomend you to TRASH that phone its TOO OLD!!!!!"
so ive make a guru thing transplan a nv_data.bin from a galaxy ACE to this and see what happend .
Please use the Q&A Forum for questions &
Read the Forum Rules Ref Posting
Moving to Q&A
LESSON LEARNT (for everyone): Please make sure to do a complete EFS backup before you do anything or you will end up like me!!!
So yeah I flashed Deodex_LF2_Cwm.zip yesterday, trying to deodex my DDFL2.
And following that I experienced total loss of mobile signal, baseband, IMEI, IMEI SV, and phone (*#1234#).
And I haven't been seeing this kinda thing to come, I did not back up EFS. (Yeah brilliant me)
So I tried a few of these:
[GUIDE] Recover your IMEI in 9 steps
Repair IMEI using EFS Pro
Reflashing from latona.pit then XXKPE; for a few times
Flashing stock ROM for Malaysia region (Froyo and GB)
Flashing various Modem.tar (DDLE1, DXKP7, etc) via Odin3 at different ROM levels (XXKPE, DDLF2, even CM10A4)
Restoring Nandroid backup from other SL user (Thanks Rich'Dawg')
But nothing worked so far yet.
Now that I checked the /efs folder is empty and there is only a folder named lost+found.
Some websites said about fixing IMEI for small fees but in cases of blank IMEI (*#06#), chances are only 30%.
And my last resort would be getting it replaced in Samsung service centre or any repair shop, which I suspect that the motherboard would be more expensive than some simple new Android phones.
Leaving this forum for the moment as to collect more money to get a new phone . . . :crying:
Lastly, thanks for all the input. Greatly appreciated.
Do you able to call anyone. ? if yes then no need to change anything. if no then you should search for imei solution on xda. there is some tutorial for fake imei.

no idea of how much it should be.
but a idea to help you,
1st idea:
go in recovery and fix permission.
2nd idea:
you said you flash Deodex LF2 in CWM, it should not touch efs folder. so, very high change of your nv_data.bin file backup still good.
OK. use any file browser look in the efs folder, see if the below file still exiting, (they are hidden file)
check on the file date. is the date older than the date you flash the zip, if yes, this is the one original from your phone.
the file name start with a dot
.nv_data.bak - ( this is your imei backup file) copy and rename the .nv_data.bak to nv_data.bin and set permission and change owner.
.nv_data.bak.md5 - (delete this file first)

Fixed permission.
I found one .nv_data.bak dated year 1994 , which I think came in when I was trying to flash some efs fixes i found in XDA.
Without much hope I tried what you said, but still nothing happened. IMEI blank, baseband unknown.
Is it possible to have the mobile phone repair shop with RIFF or Jtag or some box thingy to have this done?
i think you must change the motherboard

Mate, do you like JellyBam V.1.3.0? Because that's the only Nandroid backup i have in my phone. I was thinking to upload it to my Box account for Emergency Backup if i don't have my computer. If you like, i can upload it for you, but the size of the backup would be nuts, it's 850 MB. It's up to you.

a friend of mine ran through the same same problem and i think he did some sort of repair from a shop but later we came to know that the backup can do the task not sure whether that work or not but u can give it a try,, BEST of Luck with that..... Hopit Fix the Issue
Good luck sir! As far as I know, if you would choose to replace the motherboard from repair center, it would cost you more or less 80% of the original price of the phone. So it would seem that you have to buy a new one. I hope that a nandroid backup (as stated above) would solve the problem. God bless you! Think positive
i have the same problem and tried those solution the TS tested and still no luck, i wan't to try those nandroid backup but can't find any.

try other people's nandroid and see.. i dont think it needs a specific emei or what so ever.. as long as its a backup.. goodluck..
the problem is we can't find someone to lend us their nandroid backup.
I did it!
Bro, try use Efs Pro, http://forum.xda-developers.com/showthread.php?t=1308546
Try the new version, you can choise Qualcom version, write you IMEI number, go back to initial and do NV Restore.
My SG Fit go back to life (after maybe 4 months with 0000000000000 Imei). :good:
I´m very happy
Hope it work for you! Good luck!
A while back i decided to downgrade my stock 4.3 to 4.1.1 in order to try to unlock it from carrier... the thing is i lost my IMEI and Serial Number
The good news is i have a backup of my EFS folder (only copy-paste with "root explorer" app though... no ".img" file sadly), but I understood that the most important file is "nv_data.bin"
So... my problem seems to be like this: http://forum.xda-developers.com/galaxy-s3/help/successful-imei-repair-i9300-backup-t2544109
but only the last step (put back the nv_data.bin, delete backups of bad nv_data.bin, reboot and magic)
The sad part: it doesn't resolve anything because everytime I reboot the phone it recreates the "nv_data.bin" even if I restore the original one (the one i had before downgrading)
Can anyone help me please :angel: ?
I have also tried as seen in other posts to change it's owner into radio:1001, unfortunately it still recreates the file after reboot.
I am currently trying to go back on 4.3 to try to restore the nv_data.bin on that verison (but i don't think it has anything to do with the android version)
Anyone encountered this problem or knows a solution ? Thank you !
Hi,
I see you've already asked about this in the appropriate section for your device. Xda Assist is here to help navigate the site, not for support.... And you found your way already. ?
Thread closed.
Hi, can someone guide me as to how I can restore my lost IMEI - Serial No back to stock? using SM-G920FD (duos)
Kindly refer below to the details of my problem and actions done.
How the issue happened
1. I'm currently on stock firmware of SM-G920FD (COH8). (Local copy of COH8 flashed via ODIN)
2. I received an OTA update (COI9) and installed it. Phone works perfectly fine.
3. After doing some tests on some kernel (arters97's kernels), I have decided to revert back to stock firmware since the kernel uses Note 5 gpu driver (not knowing that someone has prepared a flashable zip for S6 flat/edge) :crying:
4. I use my local copy of COH8 and flashed via ODIN. The flash failed thru sboot.bin - that tells me the bootloader is outdated on my phone *ugh.
5. I downloaded COI9 firmware from samfirmware site and flashed it via odin.
6. It is now stucked at first samsung logo. After going to recovery it says cannot mount /efs
Fixes I made
1. I dont know much stuff with efs thingy, that's why I didn't do a backup for it.
2. First fix, (this is the worst step I ever made - that costs me into this big trouble) I installed a "something" application that requires me to format the efs partition. Well done to myself, the app successfully wipe it all without backing up efs .
3. Now the phone is stucked to samsung first logo. Period. Even Reflashing stock via odin failed. Realizing the efs files are all messed up.
4. Now, after searching thru forums, Ive come into this adb command by running this, .
/system/xbin/su
mke2fs /dev/block/sda3
mount -t ext4 /dev/block/sda3
After doing this, Ive been able boot into device, I have a working WIFI, a valid ip address.
a. no bluetooth address
b. no imei for both sim 1 and sim 2
c. Incorrect Serial Number
d. No network of course
After deep searching thru xda, Ive come across with nv_data.bin editing thru Hex Editor. It could probably return my IMEI and Serial No back to normal(i still have the imei no & serial at the back of my phone ).
Perhaps, the only way to fix this will be on a repair shop to fix my imei. I doubt my samsung warranty would help since Im constantly flashing stuffs on my phone.
Can someone share me their full EFS folder zipped with Galaxy S6 SM-G920FD / G920F (probably a single sim will do) so I could compare and edit my own imei that would be a great help and I'll give a feedback asap.
Hoping someone can help me on this. Thank you
Anyone?

There is loads of information on the forums to recover lost IMEI. Did you try flashing a modem and bootloader update. This should generate the efs folder with nv_data.bin. You still may not have the correct IMEI and serial in the nv_data.bin, but at least you can edit it.
Search the forums I have seen loads and loads of tutorials for this problem.
Not many people are quick to give out there IMEI.

No, modem and bootloader flashing does nothing.
I do already have a pre-generated-stock nv_data.bin from my efs folder.
Can you give me an example of a working thread that requires editing of nv_data via editor that works?
The problem is that their issue has worked specifically on their device, none of the Galaxy S6 users were able to do that afaik. Almost a week since i started searching for answers but to no avail.
For example this, the thread below says that I should goto this address [offset] 00188008 but in my Galaxy S6 nv_data.bin, the file is only up to 000FFFF0 offset?? That's why I need help from others to at least share their fixes or comparison of this thread below with their nv_data.bin file. If there is similarity. Forget sharing your imei to me, but maybe you can consider how am I supposed to do that fix on the other thread.
Thanks
http://forum.xda-developers.com/showthread.php?t=881162
Or if someone can find their IMEI code in nv_data.bin, kindly share to me the offset (location) of the IMEI in hex editor. That would be a good start. Thanks

I can't remember exactly the offset location but I have seen it on my phone a few weeks back. I do remember seeing a few tutorials on YouTube. I will take a look tomorrow and if you haven't it solved by then I will help you fix it....
Thanks, hoping you could help me on that.
Something is weird on how efs is generated. I backed up the messed up nv data from efs folder. Then I deleted the contents of whole efs folder then reboot.
When phone booted, to my surprise I notice that it still generated the contents of efs. Then I compared the Newly generated nv_data to my backedup nv_data. No difference -_-. Still incorrect imei was given to me. 350000000000006 format both for sim 1 and sim 2.
Phone Info app says that my imei info (www.imei.info) was from an apple device rofl.
Since its giving me same and same imei and no product code/serial code
I suspect that my IMEI was generated from embedded hardware/chip??? But i think its not possible to mess any of the hardwareparts from flashing custom roms/zips/stock firmwares alone?
Hmm I think there's no chance for it to recover? since it is always giving me Generic Imei
One user says that it could be the hardware is somewhat corrupted or cant be modified blah blah

You showed your edited IMEI on your phone, but you didn't share how ?
I think this is what Im looking for, but HOW???
1. What is that cert file? Can it be installed via phones system files?
2. Does it need third party app and a toolbox hardware to buy and install? It smells like its for technician part already :|
3. Since it needs key cert, how can I generate this? Thru the 3rd party also?
But FYI, Im not into modifying IMEI as it illegal, what I wanted to do is to restore my device's IMEI found at the back of my phone.

You have now lost the IMEI
If you still have flash the firmware is invalid
I think no way to restore the original IMEI
If change IMEI is illegal in your country, it would be a sad thing
ugh. Based from your pictures, you used 3rd party hardware tool and app something like octopus box and the likes.
You're telling me to give this to technician, as it is the only way to fix my issue?

What I wanted to do is to change my IMEI to stock IMEI (printed on my phone) so that it can connect legally to my network provider. If your way is good, maybe you can help me how to change my IMEI
Changing IMEI i.e., frying someones IMEI to hacked/stolen/blocklisted phones are definitely illegal.
Back to my issue, did you send your phone to technician/ did you have the box tool to flash cert files to your phone?
Hope you can help me thanks

Yes the octopus can do it
------------------------------------------------------------------
My English really bad, I speak a little bit more simple
If you don't have a backup EFS and your mobile phone and lost IMEI.
The solution is to use the BOX to write a new IMEI so that you will get a new IMEI
You write a new IMEI may and other mobile phone to repeat After doing this You will forfeit the warranty In addition to Will not affect the normal use of your phone
Samsung CERT is unique And only CERT must be the truth

Well still thank you for the replies, only repair via technician is the only way . Requesting for mod to close the thread. No way the imei can be reverted back via EFS - NV way, flashing stock modem, backing and restoring efs, mke2fs thingy, flashing stock firmware and so on.
There is part on the chip of the phone that literally erases the phone info for my s6.
If any can give other ways before I let go HAHAHA, but please refrain from efs,nv_data,flashing stock stuff, as the firmware doesn't have to do with restoring efs. Only the hardware device stores efs info for our phone.

If your phone is KNOX 0 x0
Then you can look for samsung to solve for you
I wish you good luck, my friend
Thanks , haha but my knox is 0x1 already
Tried to bring it to a legit 3rd party technician and they assigned a new IMEI for my phone and its working fine now.
imo I brought it first to Samsung and tells me that my warranty is void, but they can fix it via hardware replacement and would cost me at around $350. Lol no way!!!
For those who tried to do anything when all methods do not work, frustrations etc. This is the quickest way to restore it.
But thanks for the info I got from XDA members, now Ive learned that the first rule should be applied whenever possible before its too late.
To all other Explorers/newbies/Risk taker out there. Remember this one word.
BACKUP!!!!
Thanks.

Stupid to give out your EFS with potential to clone your IMEI.
Anyway EFS is individual to each persons phone as is IMEI.
Any illegal methods of cloning IMEI are not allowed on XDA .
