[UNSOLVED] Unknown IMEI/Baseband

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.

Sad enough this folder does not exist in my phone....
Have you had any idea if Samsung would fix this in Malaysia..? Or how much would that be.
I spent like 10 hours trying to look for a solution but >"<

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.

never thought deodexing gonna brick the phone.. ive deodex once without any problem.. without any doing backup before that.. lucky me.. huhu
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!

[help needed] dead network & blank imei ???

Hello everyone, i recently buyed a used samsung galaxy r. Its in good condition.
But it has one serious issue ie, no network & blank imei number.
I browse google whole day & found that this happening becoz of corrupted efs, i checked efs folder via root explorer, there is no imei folder in it :banghead: i also tried efs backup but nothing done.
Why this issue happening, is there any one who can help me out to resolve my no network issue,
I also went to nearest service center, they told to change the board which cost around rs8500 (indian).
Help me frnds, my galaxy r is without network & blank imei ?????
My last hope is XDA!

Help ???

You cannot fix it without the original EFS. You could ask the seeker if he/she has a backup of the folder. Except restoring the backup, only SSC can fix it.

The problem is maybe with just the nv_data.bin file, you may check out this thread.

Thanks for help, but will this work ?? But in my case there is no imei folder inside efs will other galaxy r efs backup will work????
I will try this & plz support me

It makes no sense to create an EFS backup of an already corrupted partition. Also, the imei folder has nothing to do with the actual imei number. It is stored in the nv_data.bin file.

Actually Sir, I format my system partition with odin and flashed stock gb rom 5 to 6 times while resolving my issue, and at time i accidently deleted the contents of EFS folder & reboot but still no network & imei..
So i again flash stock rom via odin & all EFS files(nav_data.bin) again automatically generated, is this normal ????? but no luck to restore my imei & n/w ..
Below is the screenshot of my phone

Yes, the file is generated automatically, but it doesn't know what to generate. So it either generates a fake IMEI or garbage I assume. We would need to know about the internals of the nv_data.bin file to fix it. You have to take it to SSC or someone who knows about the details.

Above method is not working.. any helps please..

Visit Service center of samsung. They can only help you now.

Hey, i jst wanted to know out of curosity...

No it doesnt backs up efs folder..hence we need external tool to backup..
CWM only backs up system,data,cache folder and kernel..

Thankyou all !!! Finally i got my samsung galaxy R i9103 from nearest service center, blank imei & no n/w issue is now solved. They told me that they change the motherboard of my fone to resolved imei & no n/w problem. & also got updated to 4.0.4.

Follow this thread to backup your efs partition.
You r on ics right now, i recommend you install CWM and flash ardatdat_i9103_ics_kernel_v4.zip first.
For Awesome Rom, visit this and download latest nightly build.
Download gapps from here.
For Installation Method, visit this thread and follow Procedure II..
Happy Flashing..

(SOLVED) Help Restore Lost IMEI & Serial No (SM-G920FD)

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

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 .

Elephone U Pro IMEI and Baseband thread

Lost IMEI and Baseband on your U Pro.
lets search for a solution.
forword:
if we flash the 2080227 stock rom we will lose the IMEI and Baseband information in Settings.
the IMEI and Baseband is still there its just that it dont show in settings anymore.
Why:
stock rom 20180227 contains all images of the official Stock Rom as dump.
also modemst1.img and modemst2.img. in that images are the imei information stored.
baseband information is stored in fsg.img
but why it dont restore also the imei info in settings ? maybe its region related. we dont know that yet.
lets Discuss and find a Solution/fix for that

reserved
here i will post the possible solution ..............
1.
This will restore the IMEI numbers into settings for slot 1.
Slot1 and slot2 will be similar then.
1. Install xposed manager APK. You have to have root for that.
https://xposed-installer.de.uptodown.com/android
2. Download in the app framework v90.beta3 and install it ( all in the app)
3. Download this app from playstore (IMEI changer)
https://play.google.com/store/apps/details?id=com.vivek.imeichanger
4. Your imei is written on your u pro box back cover.
Enter the IMEI in the app. Save it and reboot.
Done!

In ~2hours I will know if the other fix I found will work

Maybe helpful information:
For me without any changings the IMEI isn't gone. With *#06# I see two IMEI
I'm on eragon 4 but I've had to make a factory reset after update from 3 to 4 (there were some problems like system settings not working)

I guess the problem of losing the IMEI was caused if someone flashed the stock rom 0227. It was overwriting modemst 1 and 2 where the IMEIs are stored. Eragon doesn't do that.

I have found appropriate tools (also via xda), which perfectly fulfill the task...
QUALCOMM smartphone write IMEI tool 1.01
QMSL IMEI and SN writer 1.4
But apparently the tools do not support the chipset, or I have not yet found a way to use the tools accordingly.
If someone has experience with these tools…
Thanks in Advance

Already tested them a few days ago. They don't work.
Feedback of my progress so far:
I use NV ram tool to try to restore IMEI.
I was able to build IMEI but it did not flashed it because of a driver (diagnostic mode) problem.
I just have to find the right driver. Lol.
Sound funny , but I have around 100 different diagnostic drivers for Qualcomm devices.. one is the right one I hope ....

all the best man to succeed, we are with you

Been looking through XDA threads hoping to get some ideas on missing IMEI thing. I'm also trying to run a NV Backup using the QFIL program and up to now I wasn't able to do that, the blue 'start' button was always disabled(diagonal gray stripes) with the COM port and diag driver ON. I think, the problem is related to the lack of IMEI/ESN etc.., because today I hooked up my spare Moto G4 Play and got the NV bckp from it. Then, after that, I actually had a little success with Upro, I used the same diag driver which poped-up with Moto, HS-USB 9091 (instead of 900D), it's also a Qualcomm driver, found it on my desktop(uncheck: show compatible drivers to see it) Not a total success but, at least I could start the bckp. It failed, still, I've never gotten this far. Can you try and see if you're able to get the NV backup w/o IMEI#?
Is there a way to somehow convert to text the .qcn files? How about editing it, if that's possible then the imei could be written into saved files and fed back into the phone using 'restore'. Just saying, am clueless on that.
Ok, here is that link from another XDA thread and you'll find two screenshots below:

https://drive.google.com/file/d/1xawPNNMCD39nzQJaoBfwwnf0zVFCwQTA/view?usp=sharing

I am ready to try the IMEI edit on my Upro. I was dry practicing today on .qcn files extracted from Moto 4g Play, navigating the .qcn with this editor http://mh-nexus.de/en/hxd/ , finding the proper columns and rows, playing with hex./dec. conversions guided by this: (watch?v=zn_D6TEFABQ)
But I'm still missing the most important element: the actual Qfil generated .qcn backup files from my Upro, can't get it. You guys have any suggestions?

Its a placebo fix or better only a solution for fake/anonymize the IMEI for apps only!
If the provider needs the IMEI to connect to his network it is not working!
With a app on phone you can not bring back the IMEI, its stored in the NVRAM.
You have absolut no write access to this "partiton" on a running system.
for real restoring you must flash it!
