It is not possible to *repair* a lost IMEI on GS4 i9500

For reasons of brevity on this post, I ended up with a generic IMEI on my Samsung S4 i-9500 while flashing Philz CWM and then the stock ROM back. After extensiverly combing all possible threads on the subject, my conclusion is that there is no way to repair a lost IMEI on this phone when one does not have a working backup of the /efs folder.
I tried all possible methods:
- Flash stock ROM back
- Delete /efs and reboot
- Try to fiddle with copying .nv_data to .nv_data.bin
- EFS Pro to recover from an /efs I had. I noticed this was already the one with the generic IMEI
- Flash the modem twice
- etc.
Is that really the conclusion? It is not possible to repair a lost IMEI on GS4? On other phones people usually get it back when reflashing stock.
Does GS4 has some trick done by Samsung so that IMEI is not recovered?
I thank upfront whoever can enlighten me on this topic.

Either buy a RIFF box & A) Pay for something you'll never use again & B) Bork your phone to the point of requiring a motherboard replacement if you get it wrong or take it to a local mobile repair shop/someone who already has one & knows how to use it and have it fixed properly for half the price of you buying your own/without the risk.
Do the smart thing.

Thanks for the reply, so then it is really impossible to recover. Is that always the case with other models or firmwares? Can a Samsung service center repair it, even with a cost out of warranty?

From all the posts I have read in the last two days, this one gave me more hope, as it keeps saying that restoring an older ROM may help.
It is not that I have an empty /efs. I have an /efs that I backed up, but after I noticed the fake IMEI issue. Can it be that somehow this /efs still contains what I need and is just not recognized by the stock ROM I am using?
This is the data about the stock ROM I am currently using, my phone is a GT-I9500 bought in Colombia, from carrier Claro, factory unlocked, no contract (I suppose all 9500 are like that). I flashed the Stock ROM following this guide, using the stock ROM files listed there http://forum.xda-developers.com/showthread.php?t=2265477

GT-I9500 Galaxy S 4

Yep. Sometimes flashing stock roms restores the IMEI where it's a case of it disappearing temporarily. But you've already tried that, and if this was the case with your situation, you would have fixed it already. I mean, you can flash a bunch of stock roms & maybe you'll get lucky, but it almost always returns with the first stock rom you flash in these cases.
If you have an EFS backup that you know is 'good' (I.E you verified its integrity with something like kTool when you made the backup), then you should be able to restore it with kTool/similar. If you've tried that & it doesn't work for whatever reason, the backup is obviously bad.
I would be very surprised if a Samsung service centre didn't fix it if you paid them. However, you will possibly find that a local mobile repair shop who isn't an authorised Samsung repairer will fix it more cheaply (that's certainly the case where I live).
I noticed you tried to restore the backup with EFS Pro (don't know why people insist on using this app, maybe it's the 'Pro' in the name ? I don't think I've seen anyone on here successfully restore with it), try with kTool (search here/Google Play).
What you do from here is up to you, but if it were me (having tried the things you've already tried), I'd be biting the bullet & getting it fixed tomorrow, because you can try a bunch of things that won't work & you'll still have to get it fixed in a week/whenever.

This works! http://forum.xda-developers.com/showthread.php?t=2432758

Please Help !! Not Registered on Network. IMEI problem ??

Hello,
I have an S4 GT-I9500 and suddenly am having the "Not registered on network" issue. That is: I cannot receive or make phone calls and SMSs, all the rest of the phone is working OK (including Data Connection 2G/3G, which is confusing for me).
I am on stock rom Android 4.3, Baseband I9500UBUEMK1.
I think that the problem is related to the fact that a few days ago I have rooted the phone, and installed Titanium Backup to delete samsungs bloatware. However, after all deletions (I think that I have deleted only safe things), everything was working perfectly, but suddenly today I noted that I cannot receive or make phone calls.
I have read many many threads in this site, but I am still confused on what is the cause and the solution. I have checked the IMEI, and have found that the IMEI in the back of the phone is 3571****, and the IMEI reported by the phone´status is 35299****. I can´t understand what might have changed my IMEI.
I went with ES File Explorer in root mode to the beginning of the filesystem, and have found the EFS folder ... there are many folders and files in it.
I don´t have a previous backup of this EFS folder, but I have read that there are some cases that the IMEI is recovered doing some procedures...
Please help me !! I don´t have experience flashing ROMS or modems but if there is hope ...
Thank you very much.

Something similar happened to me some weeks ago, but my case was different because I lost my imei but it was a generic one, (started with0049..) Everything was fixed when I installed a stock firmware through odin. Go to sammobile, download any firmware suitable for your model and flash it following these instructions: http://forum.xda-developers.com/showthread.php?t=2265477

Thank you for your answer. Do you think that is better to go flashing directly, or a factory reset should work also ?
Am I going to have any problems with the fact that the phone is now rooted, and (I think) with Knox in "non-stock" ?
Thank you.

I don't think factory reset will work, I'd flash the firmware. Flash a stock one, through Odin.
As regards knox... If you rooted the phone you might have knox warranty void 0x1, it depends on the bootloader. When you enter in download mode you will find out. If you still have knox0x0 or nothing displayed it means that warranty void was not triggered. Anyway flash the same firmware that you have now. You can find it in sammobile web page. Hope it works!!!!!

Well, finally I went with the phone to a repair technician who fixed the IMEI problem using a Octopus Box.
The reason the IMEI was altered is still unknown.

Of course, no efs-backup available (i did one months ago right after rooting/knox-tripping, but it got lost during flashing/wiping/sd-formating) :crying:
/efs has a file in /efs/imei, but i cannot find a nv_data.bin, should the note3 really have one? Would someon be willing to share an imei-scrubbed /efs-backup? I know it will not work this way, but at least we would have a starting point...
As far as i understand it, there is some sort of a certificate for the imei on /efs, maybe it could be fixed by entering the devices *original* imei into nv_data.bin if that certificate is still there...?
So far, i think every one had knox 0x1, another push from Sam to discourage moding ?

You seem to have used the correct image but indeed it seems something wrong happened during the upgrade
On N9005 the IMEI is not in the EFS partition, it is in a separate partition (with a backup), it don't remember right now so you will have to search around a little, something like partitions 11 to 13 and 17 to 19. I doubt that those partitions from one phone can be of much use on other phone.
EDIT:
have you tried to write back the previous ROM?

I wondering if my N9005 wasn't a fake.
After analysis :
S/N is fake, not recognize by Kies
RAM => 1.72 GB
I got Odin files separated, but, no way again.
It's curious because everything else seems fine, even sensors.
If I try to uses imei changing solution, will my phone back ?

Yes, that the first thing i tried, didnt change anything, but i stayed on NB1. After i read your posting (that the IMEI isn't on the EFS partition) and snooping around Android, it really looked more like a broken baseband instead of "just" a missing IMEI. I did a lot of things (like EFS-Clear and NAND-Erase in odin), but at some point i remembered that i region-unlocked my note3 with Chainfire's tool, so i region-re-locked it, upgraded to NG2 with odin, and preso, working note3 :laugh:
So i can't be sure, but if the other people with broken phones also have used region-unlock, this could point in the right direction :good:
Thanks a lot for your help!

How do you region-lock it?

Did you update from 4.3 to 4.4.2 ??
I did update on n9005 from 4.3 to 4.4 and same problem as yours, I didn't have efs backup or anything.
Flashed all the roms and modems on 4.4 but no avail. Then I found 4.3 modems from xda and flashed 4.3 modem on CP in ODIN and baseband came to.
n9005 4.3 modems: http://forum.xda-developers.com/showthread.php?t=2475714
Your first priority now is to RECOVER BASEBAND. Everything else will be done after that. No baseband, no repair.
Mine is fixed now btw, did it yesterday!

With the same tool from chainfire, it has an option to reinstate the lock. It's probably a good idea to do this on the same firmware as you unlocked it (if that's an option, if you're come from 4.3, it's not, in my case i did it on 4.2.2 and the new firmware is also based on 4.2.2)...

[Q] My Galaxy GT-I9505 is dead

I wonder if anyone can suggest a remedy for my little problem, apart from throwing the phone in the bin.
My gt-i9505 recently stopped connecting to my provider and is showing a no service message at the bottom of the screen and a round circle with a line through it at the top. Samsung repair center say that the main pcb has failed but refuse to repair it saying that the phone was not destined for sale in the U.K but was intended for the Asia market.
My thoughts are that it cannot be the main pcb as the phone boots up o.k and also finds a satellite signal ok, the only things not working are the wi-fi and phone signal. Would I be correct in saying that these items are modular and can be swapped out? It may be a delicate job beyond my capabilities but if these parts are replaceable I do know someone that can do it.
It's a pity to dump the phone as it is only 12 months old and as new condition, so any suggestions or help would be gratefully received.
The phone is running the latest kitkat 4.4.2 ind is fully stock.

Bad efs folder. Is your imei and baseband correct?
Use/ask someone for a z3x box or a jtag.
"If someone helps, never forget to hit thanks ? "

Thanks for the reply, it's much appreciated. Yes my imei and baseband are all o.k. so I don't think it's the efs folder. The phone has never been 'played with' due to the knox problem negating the warranty. I have however played with an I9000 with many successes.
I also upgraded the phone to the latest version GNG8 hoping that this would cure the problem but that didn't work either. What would using a z3x box or jtag if it is a hardware fault?

Well as @MAX 404 once said...
The efs folder, even if shows the correct values, can go bad.
Before going too technical, did you try flashing the latest modem for your phone?
Do it too but before proceeding take an efs backup. (Many ways, many playstore apps to take efs backups)
Hardware fault. Unlikely in this case , but cannot be ruled out altogether.
Z3x box is a multi utility box which has the power to bring devices back to life and writes the imei codes and stuff properly once again.
And a JTAG + Z3x box have the ability to bring an almost dead mobo to life.
You can read more about it on xda, how z3x has saved lives. I wont say buy one, but you can always ask if someone has it.
"If someone helps, never forget to hit thanks ? "

Thanks once again for the reply. What I flashed was the newest software, I9505XXUGNG8, for the phone downloaded from the SamMobile firmware page which I thought contained the newest modem. I will however download the relevant modem and reflash. I will also ask around for someone with Z3x box, as I will be away from home now until Wednesday next I will be unable to reflash modem until then but I will report back as soon as possible with the results.

No. Just flash the modem via recovery (if a recovery modem file exists) or via odin.
After you flash keep the phone off for 30secs or more..and then turn it on..
See if anything improves..if nothing improves then just data wipe the phone..
"If someone helps, never forget to hit thanks ? "

I have now re-flashed the kernel inclusive of the wi-fi fix from this thread here
Code:
http://forum.xda-developers.com/showpost.php?p=50965837&postcount=2627
and the phone now connecting to the internet successfully. The circle with a line through is still at the top of the screen and the phone is still showing the no service message. With a sim card in place the network is showing as unknown, service state is showing as out of service but the phone number is showing correctly as is the imei. I will have a look around for someone with a Z3x box to see if they can help.
Thanks for all your suggestions.

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance

Anyone??

under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware

at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Maybe restore the efs from recovery, if you have a backup that was working.

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.

Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?

"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin
https://zfirmware.com/download-samsung-repair-firmwares/
5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

If something does not work, why do you give up so easy?

https://androidfilehost.com/?fid=24269982087001472 - this is for lolipop
Put the phone in download mode, open Odin and try.
And try the smartswitch also.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!

Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!
