i was upgrading my sgs2 to 4.0.3 i messed-up csc file with other file
now my imei is 00499010640000
A search would have yielded you *many* threads detailing how to possibly fix corrupt/missing EFS/IMEI details.
This thread might be of help.
Please don't ask me the why/how/where of this process. I've never had a problem with my IMEI (at least not a permanent one that wasn't fixed by a reboot) & backing up my EFS is part of my weekly (and any/everytime I flash a new rom or kernel) backup routine.
my problem is not yet solved :'(...is there any other way to get my IMEI back???

what to change in that efs folder
Hello People
Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.
I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.
Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.
I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?
Many thanks.

Flash a patched modem and kernel from here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << see if that works if it doesyou will always need to use the patched files.
Thanks tallman43! I'll try that. Also, I noticed now that the EFS folder is EMPTY :/. and the backup .tar I made with CWM says it's 0 bytes? wtf?
still, in phone info, imei and s/n are there. weird?
THANK YOU

Your recommendation worked like a charm. My signal is up and running normally. MANY THANKS tallman43.
Lastly, even if I sometime I decide to try out a custom ROM (unlikely at the moment, but who knows?), I still have to flash patched kernel&modem? or in case of factory reset (I will be selling the phone soon) ?That custom really messed up my phone...

I would still like to solve the problem at its roots: to fix the "not registered in network" problem whenever factory reset or stock ROM flash via odin is done. That is simply not normal. I might be selling the phone soon and the new user won't most probably know he/she would have to apply a patched kernel or etc.. ( let alone about rooting the phone).
Basically, bring the phone back to it's original sound state before I tried out the custom ROM. What can I do about that?
Hope I'm not being annoying.. just trying to get to the bottom of things

There is nothing you can do without your original efs backup.Only a service repair can fix it.

Understood. I think I have the original EFS in my SD, though I tried replacing it once and it didn't work out... I suppose I'll have to make do. Thanks for everything man
Flashing modem with Ariza patch was bad idea. Your efs folder is screwed up now and you are addicted to constantly flash this dirty workaround.
If anyone have problems with registering in network please check your device serial number first. It must be the same as on the sticker under battery. If it's not then type *#0011# and check info under IMEI CERT. If there is FAIL info then you should use any box ie Z3X to correct phone's serial number. It takes only few minutes and is cheap. It's better long-term way than patching and permanently destroying your efs informations.
If you have backup then you should flash normal modem and restore original efs partition. Then find any GSM service center with box and tell them to fix serial number. It shouldn't cost more then 5-10 dollars.

I have never flashed the Ariza patch nor have I even mentioned it on my previous posts explaining the problem. Fixing the s/n issue is indeed adviseable, but paying to correct s/n using box here where I live is ASTRONOMICALLY expensive. They should answer for never having fixed it, but they won't. Here is a hell of a lot more than 5-10 dollars, unfortunately.
Believe me , I'm no happier in applying this sorry fix every time I want to factory reset or upgrade, etc; it's the only option I have left at the moment.
Those files you have flashed, I mean kernel and modem are patched with Ariza's method. It is called Ariza patch and it is latest solution you should take to resurrect your phone because it is a destructive one.
Sorry to hear that you can't repair it as it should be especially if you want to sell this device.

May i ask a few questions about your problem?
Which version were you using when you desided to use a custom rom?
Was your phone ever rooted before installing a custom rom (when you were on official)
Did you upgrade your phone before? (Official via ota or odin)

I was on 4.2.2 leaked version ROM some guy installed at a repair service some time ago when the phone belonged to my mother. I was actually rooted using the CF AutoRoot method, with Philz CWM recovery. I decided to change to a custom 4.3 without having changed first to a stock 4.3.
The problem came when, within the custom ROM's aroma installer, I ticked an option to upgrade the modem to some build I can't remember now and my signal became screwed up. I informed this in the developer's custom rom discussion thread about the issue to which he replied that the problem was that the EFS folder tried to convert from v1 to v2 and failed (this was when I learned of the whole efs version folder change since build XXX (don't remember).
I download a stock unbranded 4.3 ROM and flashed it via ODIN, believing that would solve the issue; it didn't. Finally, I became desperate and took it to a repair service where they used box. Apparently, late did I notice s/n was not the same as the one in the back of phone. I'm guessing that would solve the problem? I don't know.
i am sorry for your loss . i wish you had all that info you learned before a try and fail. now that your imei number is a clon number, and once a box tempers with that you cant go back even if you have your orijinal efs folder or backup. you should always have that 2 patched modem and kernel files on your sd card just incase. you can use custom 4.3 with the patched files and get a signal but you will always have some lags after some time because of the kernel. and lucky you samsung stopped updating s3 officially because patched files are only for 4.3. if you dont have a desire to use custom 4.4.4 kitkat roms then you are good to go and when it comes to sell the device, the price will be much lower then an original s3.

Well, actually, IMEI didn't get cloned; of that I'm certain. IMEI is just the same as it was before I took it for the first time to repair service. It was the S/N that got changed somehow. Should I get them to correct the S/N, and use the original EFS folder (I found it, i think), would that correct all problems?
S/N number is the same with imei number as when you dial *#06# . And as i said before you cant go back even if you have your original efs folder. Dial *#06# and check your imei number from an " imei check site " you can find on google search. That will tell you what i mean.
There are: IMEI, device serial number and Android serial number. First two numbers are on the sticker in battery Bay. They must be correct because are used to authorize IMEI certificate.
Samsung's IMEI begins from 35.....
Serial number usually from RF......
If you see serial number in HEX format in phone's info section, something like f1abcadef1.. than it is android not device serial number and this mean troubles with authorize SIM card in operator network, even if it shows proper signal power.
I don't know there is any secret code to display serial number but there is plenty of phone's info apps in playstore which displays this alphanumeric string.

Hey guys,
Sorry in advance for what is no doubt something that's came up a few times in the past (as is clearly evident by the posts). I've spent a long time trying to get around the issues with this thing so hopefully I can explain what I've done so far which might help.
So, basically -
My brother had an S3. The screen broke (glass only) and he asked me to repair it. This was a few months ago. Inbetween he moved to using a Windows phone and had the S3 sitting around until he eventually decided to hand me it to repair a couple of days ago.
Now, the phone was working flawlessly prior to him turning it off and switching over to the Windows phone. The S3 sat dormant for a few months, battery out.
When I went to turn it on to test the screen and buttons to ensure that's the only fault, it wouldn't get past the boot screen.
No huge deal there.
Upon checking in recovery it was unable to mount the EFS partition. I managed to get round that.
It still wouldn't boot, so I flashed a new ROM and it booted up fine however was in "Factory mode" with IMEI starting 0049.
I've done a fair amount of searching and came to a few conclusions but essentially :
How I don't know but his EFS folder was competely corrupt and essentially contained few files, none of which were IMEI related. I have no clue how this has happened but it has.
I've managed to get the phone working ALMOST flawlessly by restoring a stock EFS backup IMG using kTool, I HAVE the phone's IMEI and serial which are printed on the phone itself. Only issue now is that the phone can't connect to any networks - because the IMEI is a default.
So, I've dug around in the stock EFS backup IMG that I was able to find (which has got the phone working great, minus mobile networks) and found that the IMEI folder contained a file "mps_code.dat". Upon opening this file it's basically empty. I assume this is because it's a stock EFS I located.
Does anyone have any clue how I can input the IMEI into this file? I tried to decompile the IMG, type it into the file and save, then recompile the IMG however kTool doesn't recognise the newly created IMG file and crashes, then restores the phone. Is there a specific tool I should be using to make the IMG and can someone root into their "mpd_code.dat" and tell me the format that it needs to be in? (I don't need or want any IMEI numbers, just the format that the file is. Just open it in a text editor through Root Explorer (root\efs\imei) and star out the IMEI if you can).
Just to clarify before anyone jumps on it - I'm NOT looking for the file(s) OR the IMEI numbers on anyones phone with that request. Simply the format in which it should be in. I'm simply trying to put the IMEI for the phone ONTO the phone so it'll recognise networks and work as it should. Everything else is absolutely fine now.
So just to clarify the options I've boiled down to :
Recompile the efs.img with the correct IMEI within - if someone can tell me how that'd be great - then restore it on kTool.
OR
Edit the on-phone mps_code.dat with the correct IMEI but I need the format (if someone could peek at theirs that'd be great).
Thank you in advance all and sorry for the story! If I manage to get this to work I'll upload a tutorial with all the relevent files required which I know will help a lot of people.
Cheers
Mine mps_code.dat have 3 letters in it i-e 'TNL' which is csc i think. And imei is in efs1 and efs2 partition you can see in pit analysis thread google it if you don't know anout this thread.
Only thing which you can do is give phone to repair shop they have boxes and tools which can write imei. Or take backup of efs1 efs2 and efs of other phone and restore it in your phone.you do backup/restore using partition backup app in playstore by wanam.
Thanks for your reply. I will try to locate someone else I know with an S3 and pull their EFS - hopefully something will happen that's of benefit.
In the meantime, I'll focus on this as hard as I can to get it sorted. I've managed to go from having the IMEI reading as a random 0049 one, to "Null/Null" which means it HAS been written to (or does in my mind), just with nothing rather than the correct number.
If I get anywhere I'll update this thread, and if im successful in the repair I'll create a How-To based on what I did.
Cheers
I can repair your device. Had the same problem with my mothers phone.
The problem is that samsung changed the style of the efs format years ago and the S3 was falling in this time.

Hey mate,
Want me to PM you?

I had the same problem days ago and I couldn't connect to sim network.
What I did was flash stock rom using odin and then a custom modem and a custom kernel I found in the internet. At the end it gave me a normal imei number (not the [email protected]%) but it wasn't my original imei... nevertheless it can connect now without any issues .

Hey bro,
Do you remember specifically what ROM, kernel and modem you flashed? Ive tried this with no luck so interested in trying your combination.
Cheers
Ok guys this is exactly what I did:
1- backup all your data.
2- download a stock 4.3 jellybean rom from sammobile (I used the Trinidad and Tobago version because I live in Mexico but that shouldn't matter), autoroot cf for i9300 4.3 from their website and twrp 2.8 recovery, again from their website.
3- download this especial kernel and this modem:

https://www.dropbox.com/s/tky93zds14kt1hz/Patched_XXUGMK6_modem.zip.zip?dl=0
4- Proceed to flash stock 4.3 rom using odin 3.07.
5- After stock rom is installed flash the root cf file and recovery tar using odin.
6- Now that you have a rooted stock rom with custom recovery proceed to flash both the especial kernel zip and the modem zip using twrp recovery.
7- You should now be able to connect network.
Good luck.

Thanks bro, will try that in the morning!
Hey mate,
I started the process of this today, using a stock samsung FW that I updated to using Kies.
Unfortunately the end result is the same, 0049 IMEI number.
What I'll do is I'll download the T&T 4.3 from Sammobile and see if that makes any difference.
Thanks again,

Hey hey,
Right unfortunately all of the above doesnt solve any issues im having with the IMEI.
What I'm ultimately trying to do is find out a way to fix this, without having to use third-party hardware or a samsung service station.
The real reason is that I don't think the average user should have to go that extent to fix this - it's ultimately Samsung's fault.
Android is designed to be customisable allowing users to go up/down versions as they please (provided it's compatible with the hardware of their phone).
Just a thought -
is there any possible way to "bake" the old style EFS into a newer rom?

Hey All (that are viewing this).
The above procedure didn't work. I have managed to get the IMEI to change from 0049 to NULL/NULL and back again at will using a blank EFS restore file that I've got, however can't figure out what and how to change the files WITHIN the EFS restore to the correct IMEI etc.
I'll continue my search and if I come across anything, I'll let you all know on here and create a How-To.
Cheers
Hey all - just a quick question on this.
Does anyone know how to modify the server to which a program points to check for user credits etc? There's clear reason I'm asking for this, however for obvious reasons I won't elaborate further right now.
Cheers

I have a samsung galaxy s7 sm-G930F which is bricked. no imei anymore and no efs backup. can u help me fix it?
Ok so recently I was successful to root my SM-J110F (Vodafone, AUS).
I had found a forum on xda for a custom ROM for SM-J110M.
(link) - https://forum.xda-developers.com/android/software/rom-cleanertlite-os-j1-ace-t3585567
I flashed the ROM using TWRP and it worked.
However sadly, the ROM isn't really that great. The IMEI shows it's "null / null"
so I cannot fix it. The forum hasn't been active so I cannot get a response from the person who made it.
I was wondering if there is any way to fix it and I know I have a custom ROM for SM-J110M but I just want to know if it can be fixed.
Also, since I installed the ROM, the phone says it is a SM-J110M. I was wondering if I could flash in a stock SM-J110M ROM from SamMobile. I tried flashing it using ODIN, but it didn't work.
I really need your help, because I want to stay in 5.1.1. otherwise I'm just going to have to go back to 4.4.4. which is really old.
Problem can be solved and to fix that problem you need manualy to write IMEI and Serial number .
To write IMEI , and S/N you can use Octoplus but Changing IMEI or S/N number which doesn't belong to you is Ilegal so do at your own.
Here is steps for you to follow.
https://www.youtube.com/watch?v=F5k-jKCruv8
I have replaced my S3's broken screen with a new one. The think is now i have "baseband unkown" and "IMEI unknown" and i can't make any calls. I have no network. I have read numerous threads here on xda and elsewhere but nothing seems to work. I haven't backed up the efs folder nor the IMEI. I don't even have the original screen with the IMEI on it. (If i only i knew back then) . I don't even know what version of I9300 i have. I think is the Exynos one. I have installed many Stock roms with different firmware and custom Roms but nothing works. I even tried to flash different modems but still nothing. Is there a way to find my IMEI and restore my baseband? Now i am on lineageos 14.1.
There is only 1 model of the GT-i9300.
If you flashed the latest stock ROM with Odin and the imei does not reappear, it likely that the EFS folder has been corrupted. This can be corrected by flashing the phone via jtag but you will need the original IMEI.

So basically it's a lost cause. I don't have the IMEI. Is there a way to read the IMEI that is hardcoded on the board?

Not that I know of.
Do you have the original box, receipt, or cell contract? The IMEI is sometimes printed on these items.
