How I fixed a generic IMEI without any /efs backup on my I-9500

Hello all,
I would like to share a method that solved this tricky issue with my S4 GT-I9500. While flashing with some new ROMs, I ended up with a generic IMEI on my S4. I read everything I could find here in XDA foruns, and no method worked for me. This one below, from fellow colleage douglasgalves at brasildroid foruns saved my phone. Here the link to the original post (portuguese only, sorry)
http://brasildroid.com.br/discussoe...efs-resolver-esse-problema-11.html#post299796
The method is quite simple, and althogh it does not make complete sense (why Trinida Tobago for example) it worked for me! Here it is.
1. You have a I9500 with a generic IMEI.
2. Install a official stock ROM with ODIN. Not any Stock ROM, but specifically Trinida & Tobago April 2013 ROM. You can browse it on Sammobile, or also get it from this link on XDA -> http://forum.xda-developers.com/showthread.php?t=2257645
The ROM I used is:
Build Date: 24.04.2013
Region: TTT (Trinidad and Tobago)
PDA: I9500UBUAMDK
Changelist: 534999 Android: 4.2
3. Once installation is finished, disconnect the cable;
4. Reboot to recovery and wipe data and cache;
5. Install KIES on your PC and let it update to its latest version.
6. Once KIES is updated, connect your S4 to the PC, no need for USB Debug, etc, just connect it.
7. KIES will detect it and say a new version of firmware is available. Perform the update. It takes a long time.
8. Once the update is finished, you get a dialog in KIES asking you to disconnect and connect the cable again, with a confirm button "Confirm". This is the moment it fixes your IMEI. One more reboot and voilà, your IMEI should be back.
I have no idea how/why this worked, if someone more experienced can explain, I would like to understand.
Also, no idea if this would work on other models, with a different ROM, or on a Mac instead of a PC, or with steps on different order. All I know is that, by doing exactly this, I gave life back to my beloved S4.
Now, off to make some 5 backups of the /efs folder before flashing ROMs again.
Good luck there with your generic-IMEIed S4s!

Did some more tweaking to try to understand what happened. Hope some guru can jump in and help me.
1. After I recovered my IMEI, I installed Philz Touch 5.11.2. It went well, I rebooted in CWM recovery, then chose Reboot->Root. It rebooted the phone. Then I went to make a backup of the /efs folder with Root Explorer, and discovered that despite it looking as rooting went well, the phone was not rooted.
Question 1: Why does Philz did not get to root the device? At that stage the firmware version was MG9 for region TTT (Trinidad & Tobago). Is that firmware somehow imcompatible for Philz to root?
Then ...
2. I flashed Firmware for Colombia with ODIN (my phone was bought in Colombia) from April, version UBUAMDE. Got Generic IMEI again. Then followed the same procedure from post 1, and got my IMEI back with KIES. The strange thing is that on KIES, my phone still shows as TTT (Trinidad) after that.
Question 2: It looks like more than the ROMs, it is the last step on KIES that recovers the IMEI. Is it so tha ODIN may be screwing up the IMEI?
Question 3: why I keep with my phone showing as TTT? Is that a problem?
3. Then I flashed the ChainFire recovery. Strangely, this went well and rooted my phone, so it may be something with Philz. I again flashed Philz and it installed well.
Question 4: may I get any problems by using Philz but having rooted with Chainfire?
Thanks a lot for any clarification you gurus out there can give me!

Thanks
You've given a considerable amount of hope to those that are stuck on the genereic imei. Thank you for providing this solution.
However, I am stuck:
After using ODIN 3.07; clicking nothing other than PDA for selecting the firmware you said to download: Hotfile:GT-I9500-TTT-I9500UBUAMDK-1366814146.zip The firmware was successfully installed.
Then before the boot completed, I went into recovery and wiped data and cache. The phone restarted and it booted up, Kies was already updated to the latest version. So once the phone booted up, I connected the phone to the computer and kies displayed this message:
Your device's current firmware version is not supported to update firmware via Kies.
Current firmware version: PDA:MDK / PHONE:MDK / CSC:MDK (XXX)
How can I go about resolving this issue?

As I said in the second post, I also got successful using the ROM for Colombia from April.
I would sugesst you to go to sammobile's firmware database. Download any older ROM which supports firmware via KIES (there is an icon showing that over there) and do the same procedure. It looks like what really solves it is the final step in KIES.

I think this is due to flashing Previous Version of Modem (Its Including in Stock Firmware). When You flash Previous Version of Modem, Somehow IMEI retains. Here are some facts:
1) When we try to Flash any MOD of any dev then its depend on which Modem (i.e country's Firmware) the dev is using.
2) After flashing the MOD, Our IMEI becomes Fake.
3) Flashing Previous Version of Modem take back the IMEI.
In your above method you did the same. You flashed the Whole stock firmware but too old by date. After flashing, it retains.
BTW, have you checked your IMEI after flashing the Firmware using ODIN.? It was there.? was it Generic.?

Notice that I never refer to mod ROMs. I got a fake IMEI by flashing stock ROMs with ODIN.
Even during the recovery process, when I flashed the old stock ROM, the IMEI is not back. It only gets back at the last step with KIES.
When checking the IMEI after flashing with ODIN I get always the generic 499 IMEI.
Looks to me like something not going well with ODIN and 9500.

Flashing ROM from ODIN given you Fake IMEI.? This is something strange. We all flashed from ODIN & never got that. BTW, If its like that, I would recommend above ^ ^ your steps but wait...... Did you flashed any other country's firmware.?

It is indeed strange Disturbed, but I can reproduce it. I flash for example, April ROMs (happened with all countries that I tested, Trinidad, Colombia and Brazil), the IMEI gets generic. It is not that the /efs folder is deleted. It is there, it is just that somehow, the IMEI does not get correctly read from the files that are there.
It only gets fixed after KIES updates the ROM for the latest one, and only at the very last stage where KIES ask to disconnect/reconnect the cable.
I first get into trouble when after flashing CWM Philz, I tried to restore stock ROM.
I live in Brazil, but travel very often on business to Colombia, and bought the phone on a good sale. That is why I am trying different countries, but the problem first happened when re-installing Stock ROM for the first time, and at that time I was just using the ROM for Colombia.
Only when things got bad (generic IMEI) I tried other countries ROMs, modems, etc, and finally got to this method that fixed it for me.

Hi have you taken a backup of the EFS and saved?
U are a lucky guy u hv it all this working
As per what i know possibly there will be 1 more folder in the system root other then efs main which has imei details etc which must be corrupted and takes place while flashing so u have fake imei
Also check do u have any lockscreen issue???
I m telling this coz I was mad solving imei issue for 2 days with note 2 just a week ago

*FIX*
I had the same problem, so I did the following to fix the problem:
Root the device,
Install CSC Changer,
Select the CSC which matches the firmware you are trying to update,
Then start the guide above again from the beginning (including reinstalling the firmware through Odin, even if you are currently using it - to remove the root...)
and now Kies is updating my device!
*UPDATE*
IMEI is not fixed...

Thank you for your suggestion.
I've tired CSC Changer, but to no avail. After changing my CSC to TTT, the phone is restarted, and I put it in download mode; follow all the steps above, but I still see XXX on KIES.
I even tried changing my CSC by opening Preconfig via android terminal emulator, but I still see XXX on KIES.

Please note that KIES does not require Download mode, just connect the phone to the PC running KIES. Maybe it is that, I don`t know.

Hey 123hiten, I had no lockscreen issues, only Generic IMEI. Solve it with KIES.

So now I have tried this solution in many different ways,
even though kies does update the FW, it doesn't restore the IMEI,
So on several occasions after updating and not see'ing the IMEI being restored
I put the old Columbian FW back on and restarted the process following every last detail exactly as stated but to no avail....
So I can only conclude that this solution must not work for the I9500 (Exynos S4)....

It is really frustrating when a solution works in some cases and not on others. Sorry to hear it did not fix it for you. But for my I-9500 it fixed it perfectly. I do not know why :/
One thing I may remark: the IMEI only came back on the very last stage, when after finishing the upgrade to latest firmware in KIES, I rebooted the phone, disconnect the cable, connected it again and pressed "Confirm" on KIES. At that exact point it fixed it. I did not have to do anything with CSC.

I did exactly as you said but the Kies button said "OK" not "Confirm"...
and the only reason the CSC change was required for me was to allow my device to be updated by kies (if your device was from Columbia & you updated it with that fw that may be why you didn't need to change the csc... as the csc was already the Columbia csc)

Device is from Colombia but somehow it let me update via KIES using the TTT rom

@partimer, I am curious, what app or program did you use to backup your IMEI after restoring it to its original form or did you just copy the efs folder.
Thanks.

Copy the efs folder using root Explorer to the Sd card. From there I created a tarball and backed it up to my file server and cloud.

From my time on the S2 I had efs problems too. It was established that the IMEI number is individual to each device and is not included on any firmware be it stock or custom. Several roms now automatically create backups when being flashed so it's worth exploring your system to find any backups.

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.

[Q] sm 900, null imei and unknown baseband, no backup of efs or anything

hello guys,
i have sm-n900 galaxy note 3, my problem is that i rooted the phone before 4-5 months, at that time it wasnt successful so i flashed stock firmware ( N900xxudna6_n900odddna3_inu ) it was all working well for 4 months, now last night , i wanted to root it again, so i tried by flashing ( cf-auto-root-ha3g-ha3gxx-smn900.tar.md5 ) but it got stuck on screen "firmware upgrade encountered and issue, plz select recovery in kies and try again". so i again flashed back ( N900xxudna6_n900odddna3_inu ) and my phone started up, but no i dont have any signal, it says null imei and unknown baseband, i donno what i m supposed to do, i dont know what efs is or anything, its so complicated and confusing, sm 1 plz help me in simple ways.
P.S : i know there are lots of threads regarding this, but i have very little knowledge about rooting and stuff so i cant understand those technical words, so plz help me,

Search the storage for any backup...

try one of the latest firmwares. if dont solved, no solution. you can send to service. if no warranty sptbox or octopus box fixed it with super imei operation. it cant turned back original imei at this time.

I had the exact same problem when i installed the Stock S5 Final for Note 3 on my phone. Everything appeared fine at first, but i had no sound and the phone was rather laggy. Checking out the baseband and IMEI gave the whole null etc. Even flashing back to stock didn't sort it out. I too had no backup and the sorts, as i'd just bought the phone and wanted it rooted and running custom roms (fortunately i know how to root/flash well). Do you have any sound when booting the phone up? If not, then it looks like you may have the same issue i had.
What sorted it out for me was flashing the newest modem. As soon as i flashed the latest N9005 modem (I have the International Note 3), all started working well and the IMEI returned. I'd suggest trying that route if all else fails. Flash the modem in Odin, then return straight to download mode again and flash the modem again. That usually makes sure it flashed properly.

[Q] Galaxy S5 b0rked using ODIN. IMEI lost. HELP!

Hi All
I have an Exynos Galaxy S5 (SM-G900H), and I done an ODIN update on it and it completely borked up the IMEI so it cannot be used on the network, and I cannot use Kies/Smartswitch to do a recovery as it rejects the serial number for some reason.
Is there anything I can do? I don't have a backup, and I can't seem to root it using towelroot. It's still running KitKat, not Lollipop.
I also tried multiple G900H firmwares but it borks up when flashing hidden.img but was able to get it going when a site suggests extracting the hidden.img and flashing it. The phone works, but the IMEI info is borked and I don't have a backup of the EFS.
Is the phone totally frigged and I would have to hock it on eBay as parts? I'm not sure if sending it to Samsung would help as that phone is a grey import. Do I have any other options?
Thanks in advance.

Anyone???

You tried to install the stock firmware ?

Yep, sure did, downloaded stock firmware from SAMFIRMWARE for the G900H. Tried Asian roms, Middle Eastern ROMS. I even tried a PIT file, but still no go.

I wonder why people won't reply. All I want is the original IMEI back, not this 0049 IMEI that seems to occur. I guess the phone is cactus and has to be sold for parts? I have tried everything under the sun to try and get it working from flashing ROMS, even tripping KNOX and rooting it.

Without backup you can't get back ur imei the only way is flash CERTIFICATE end QCN with octopus box

EFS folder is in the root section once you delete it , it does not really come back by flashing roms as rom flashing does not touch that folder. Once its corrupted there are different ways to get it back but you need special devices for it like mentioned earlier "octupus box" is one. Try to find a professional repair shop which also repairs software. Maybe they can help you. Samsung service centers also sometime repair IMEI if you have original purchase receipt and your phone isnt rooted...but you can still try. I messed up my Galaxy Alpha and instead of selling it for parts it sold it as a "Demo unit" with everything working but calls. Someone might use it as music player or a camera.

I have the same problem. SM-G900H made in Vietnam. Anybody may help me? Thanks in advance.

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
https://www.blogtechtips.com/2017/06/24/easily-restore-samsung-device-firmware-with-smart-switch/
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.

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?

"...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.

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

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!
