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
Colombia
GT-I9500 Galaxy S 4
PDA: I9500UBUAMDE

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.

[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.

G928F bought with frp,no imei after frp reset. Help

hi, short sad story:

Please One of main forum rule is dont bump threads. I know youre in a rush because u wanna know whats going on on your phone but keep this in mind.
My suggestion. Get Samsung Kies, hook up your Phone in Downloading mode and do a total restore. If this will not help you can also try samsung firmware downloader and flash everything custom to stock via Odin. Try first method if this will not help, pm me. If the hole thing will not work i think your EFS partition is bad or corrupted maybe.

I had a similar problem, the only way I managed to fix it was by using Samsung smart switch. Here's how:
I am not responsible if this ends up destroying you phone
1- download Samsung smart switch to your pc http://www.samsung.com/us/smart-switch/assets/downloads/Smart_Switch-PC_setup.exe
2- Put your phone into download mode ( Turn off your phone, press the volume down + home + power button together and then press the volume up)
3- connect your phone to your pc via USB cable
4- open Samsung smart switch
5- on the top right there is a option button click on it
6- now click on emergency recovery
7- now click on device initialization tab
8- now enter your model name. For example: SM-G928C
9- now enter your serial number. You can find this in your box.
10- after that agree to everything and it will start downloading your original rom. This will take a while.
After that hopefully you phone will boot up.

allready tried everything you writte. didnt help. but thank you guys for helping

thanks for help grsjohn, i havent fix efs yet. because i dont have so much time. just reading a little a day about it. i havent any efs backup or something.
can you tell me little more about efs? can i flash efs or recovery it without box? if its hardware, how you fix baseband? i tried only apps what need rooted device to solve this problem(with no luck). nothing else yet
thanks guys for help to solve the problem
grsjohn said:
Hello, I had many phones from clients with your issue, it's a hardware issue, baseband got damaged, if you flash different firmware versions and fix efs an result is still baseband unknown for sure is hardware issue. Probably guy from who you bought that phone knew about this problem, baseband cannot get damaged after frp reset, I do this kind of operations often and never had problems

Samsung Galaxy Sky J3 SM-S320VL TracFone not flashing....

Here is the issue. A friend of mine had gone a bought a Galaxy Sky SM-S320VL from TracPhone. And had been using the phone without any problems until a couple of weeks ago. Then he decided to do a Factory Reset. Instead of doing the software reset, from with in Settings, he went and did a HARD Reset without unlocking the google account. And guess what, he can't remember the account information for that phone. And came to me to reset the phone. (As I had to deal with this problem in the past with other people and their phones.)
I have downloaded the only stock rom I can find for this phone and flashed it with Odin3. But for some reason the flashing of the rom is never done. By this I mean, the phone downloads the rom as Odin sends it. Odin reports a Success with the flashing. But, when the phone reboots. The system has not been reset and FRP is still active.
I have flashed only the AP, and the phone reboots directly into setup and shows a message about an unauthorized Factory Reset.
I have flash all 4 files in the ROM set (BL, AP, CP, and CSC). and Odin states the flash was a success. The phone reboots, goes to recovery and states Starting System Update. Goes so far into the update, then stops and shows Erasing. After a short time of showing Erasing it reboots to setup. Where again the phone shows the message about authorized Factory Reset.
I have used Odin3 v3.9.0, v3.11.1, v3.11.2, v3.12.5. And I have updated to the latest USB drivers from Samsung.
So my question is this. Has anyone had come across this behavior before? And how can I get past this?
The phones particulars:
Name: Samsung Galaxy Sky
Model #: SM-S320VL(GP)
OS v: 6.0.1
Firmware #: S320VLUDU2APJ3
Model #, as reported by Downloader: SM-S320VL
Note: As a strange side effect of when I flash all 4 rom files. For some reason once the phone has failed the system update, erased and has reboot. I have complete access to the phones User data area from within my computer. But, I am unable to access the phone with adb.

Hey folks,
I'm having the exact same issue as the OP. Odin does a successful install on the phone but I get the unauthorized reset message and then Wifi does not work when prompted on the next screen.
Is there a tracfone version of the rom or a fix that anyone here knows of? Thanks!

@drasnah
I have yet to get any kind of reply from anyone on this. Either now one knows, and is not stating so, or doesn't care.

I have seen the wi- fi fix in another thread.
Modify /system/build.prop:
ro.securestorage.support=true to false
Hope that helps!

First this is not a wi-fi problem it is a re-flashing of the rom problem.
Second, I do not have access, root or otherwise, to any of the system files on the phone.
Third, with the first two in mind this possible solution is of no help.
Fourth, Re-read my original post. I have given complete detailed information as to what I have access to and what I have done.

Can someone send me a download think for this phone i downloaded one but it won't flash it keeps failing

This device has been locked down by Tradphone and Samsung. It gives errors flashing even the correct stock firmware. It's a piece of garbage. NEVER buy anything from Tracphone. Garbage company. You'll never fix this issue. Only pushed updates will flash via software from sammy and tracphone that is built into the rom..

Not sure if that's correct? It depends on the firmware and odin version being used.

Post more details on the error, screenshots, firmware and odin version used.

Need to know if works. Or if needing to settle for a different route.

J3 sm s320vl... tracfone root availability? Just bought phone hopefully got a good one to root? Or maybe someone knows who maybe be able to... please help

No updates? Interested, I have the same phone.

There is no solution for this phone. It will forever be a Trac-phone.
Yes, it nice to imagine what could had been. If there was a fix for the locked bootloader. Its encrypted, and is highly unlikely to be broken by anyone.
Do not flash the boot.image that some people have suggested
Although that method works on some devices such as the AT&T Samsung Galaxy S5. In this case flashing the boot.image from an unlocked device does nothing but places the phone into an even more precarious situation, that makes it unusable even as a Trac phone.
While its true that this very low budget phone could had been decent with a custom Rom ,
You will not be able to get it working.
I have one that belonged to my daughter a couple of years ago and I managed to get it boot into the system again.
Its only function is as a calculator, or preschool game, the cellular reception and Wifi connections are highly unstable and will not stay connected.
Now it serves as my nieces play toy. I would donate to some poor person at the Salvation Army it if it was useable.
By the way, for anyone reading this.
If you have an old phone that is useable. You could dramatically help a Homeless people, by gifting them with a phone especially, if it has some minutes on it.
This gift will help them schedule job interviews, doctors appointments , etc and you will feel good knowing that you helped someone in need.
I have done this before, and will be dropping off a Blu phone, and Kindle Tablet this week.

I have permissible SE Status but can not achieve root on this device. Also, I have not found that anyone has had success rooting this exact model.
To be clear my device is the 2016 TracFone Samsung Galaxy J3 Sky model : SM-S320VL
Build S320VUDU1APG2
Hardware Version S320 VL04
I have found reports of people with S320VLUDU2API3 stating that the were able to achieve root and then assumed that it must also be possible with S320VUDU1APG2.
I am usually the guy that can figure these things out, very often before others. But I have had no success gaining root on this device using published methods. Also, I have not seen one example of someone with this identical device who gained root.
You are apparently the Wizard of these Samsung phones, so if you know of a definite way to root it, please point me towards the solution. I would really appreciate it.
I would love to root this phone, get it working again, and gift it to lady who was beaten by her husband and she is now living in a homeless shelter with her two children. She could use a phone to help with her job search. She would appreciate it.
At the moment this phone can will not keep a signal and I can't attempt the build prop solution without root.
Thank you.

See the thread below. Root was gained, albeit temporary. However I believe this is due to kernel panics which may be solved by a few build.prop edits. We had to do the same on the J327T1.
https://forum.xda-developers.com/galaxy-j3-2016/help/samsung-galaxy-j3-sm-s320vl-rooted-t3561762
Also if you firmware S320VUDU1APG2 then why not just update it to the firmware that has been reported to work?

I have found one these phones left on a table of a food truck area, screen was cracked - the device was only getting the android guy with triangle on it, I done some research and found the stock rom and flashed it with odin; as some have mentioned in comments above I also experienced wifi issue, so I thought I had installed incorrect rom - downloaded a different one this was a combination file that was the factory repair rom used for testing the device, but wifi worked - it wasn't a fully working telephone it didnt have the app store, well it really didnt have any apps, but I found I could copy over apk files from my PC to the device and then install them, so the phones not completely useless or junk --- it could be used for something. I myself am using that device as a security camera using IP CAM app works great. I was actually using this device for quiet some time as my roku tv remote, because my actual roku remote grown legs and walked off... i havent tried this, but I am sure you could install a launcher apk such as "apex launcher"
well i wasted enough of your time today...

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

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

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?
http://www.mediafire.com/file/a2fdo0xm9nat5jt/N910CXXS2DPJ3_N910CZTO2DPE2_ZTO.zip - this is marshmallow
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!
