i9300 imei is 0049 (confused with too many methods) - Galaxy S III Q&A, Help & Troubleshooting

I am trying to repair my nephews i9300 with imei showing the fake 0049. I have been using smartphones for a decade now and it usually takes about 4hrs to 2days to solve a problem.
The first few things i read were the *#4636#* code which was not working on 4.3, so i flashed 4.0.4 but after flashing i realized it was not for reparing imei so i did not go through with it.
now the problem here is that 1), there is a galore of methods for fixing this 2), i dont wanna do anything too risky and brick the mobile of my nephew.
If it was my own phone i would have been done trying about everything by now but i am still reading around to see the surest and relative fix to my dev/prob.
Btw unlike from what i have read, his Imei got corrupted while he was asleep not flashing any custom roms etc.
Atm i am downloading the XXUGMK6 and will go through with flashing it before i install XXUGMK6 Modem.zip
XXUGMK6 Kernel.zip.
(i could not find the firmware for my country btw currently downloading one with OXA at the end.)
I hope it works out but any clear advise would really be helpful here.
Thanks.

@the boy plunger: I guess, there's no efs-backup.
What modem is actually installed?

No backup, im currently flashing xxugmk6, let me get back to you.
.

Baseband is now i9300XXUGMK6. (thats the modem?)
Tried this method
http://www.androidveterans.com/solve-registered-network-galaxy-s3-i9300-issue-restore-imei/
First time with only PDA option, after ODIN was done, it gave me null/null IMEI, after flashing the patched Kernel and modem it went back to 0049. I checked CSC with *1234# and it was UNKNOWN.
Tried again with ODIN with PDA,CSC and Modem this time. After Odin the IMEI was 0049 instead of Null. After patched files flashing nothing chanded. (though CSC shows in *1234# menu).
Used this for flashing in Recovery.
CF-SGS3-CWM-v5.5-v1.2.zip

@the boy plunger: settings…info…baseband views your modem.
MK6 isn't actual, neither build nor modem. So try to update via OTA or KIES. (If they deny, you've to reset counter & status by TriangleAway first.) There's a little chance, that you get your IMEI back during update. Otherwise, let it repair by Samsung-service. All these witchy IMEI-procedures are either outdated or didn't work generally.

I am at 4.3 currently will it update any further from Kies?

Btw 1 thing, He said he woke up in the morning it was saying "NOT REGISTERED ON NETWORK". He dint do any flashing or anything.
I think phone was working with the fake IMEI (0049) for more than a year and just stopped working when casue conflict between Wifi and Network radios etc.
What if i goo back to 404 and try the *#4636#* or similer methods?

Going back to 4.0 is worthless. IF there ever was a valid IMEI/efs-package, you messed it up in the meantime.
Either update-procedure repairs or service-center or going on without telephone-functions.

What about these methods?

@the boy plunger: these are the witchy things. I only read about and didn't try, so go your way.
Maybe, the patched modem helps.

[Q] Is it possible to patch 4.3 modem?

Hi, can modems for 4.3 be patched? I know that currently Ariza patch supports all 4.1.2 except ones with MG4 modem because it uses the new efs v2, and i am asking that because i'd like to upgrade from 4.1.2 to 4.3, but, i got to have patched modem, because i'll get emergency calls only, so, is there anything yet to succesfully patch efs v2 modems on 4.3? Thanks in front.

No, everything is fine with imei and serial number, the thing is, my phone is repaired with z3x box, and now i can only change 4.1.2 roms, and then patch them with ariza patch (only 0.4 working) and i cannot use efs v2 roms/modems because i will have Emergency calls only (i will have the signal, imei, and serial number), so i have to patch modem to connect it to network (it says succesfully conected to network, but emergency calls only), i have read that i can patch with zuluman, but i am not 100% sure about that.

Man if you have z3x box everything is allright im not sure why u needed ARIZA patch anyway. It's only for S/N 00000.
But if you're looking for patched 4.3

The thing is, z3x currently patches and fixes only to 4.1.2, when my imei gets broken i have to downgrade to 4.0.4, patch, then upgrade again to 4.1.2, z3x doesn't support 4.3 android yet, and the thing is, when rhe phone is repaired with z3x, every single time when rom changes, or just reflashes, i get Emergency calls only, and i have to use ariza patch to reroute modem, and if you understand, i don't want to have risk fixing my phone again if something get's messed up, i'll look up to the thread you gave me.
P.S. i have read that ARIZA patch doesn't fix SN 0000 but only network issues like Emergency calls only after flashin (that says in one thread that has tutorial).
Edit: About this thread you gave me, i tried flashing stock XXEMJ9 and MK6, tried with both, patched MG4 modem, nothing, emergency calls only, also tried zuluman modem patcher v2, extracted original modem.bin, patched, also nothing, Emergency calls only, i am almost sure that z3x has messed something up, like i am stuck forever now, i'll consult with some specialist in service center
Same here...but z3x can now works with 4.3...i have the new repaired efs backed up..so no problem if IMEI gets messed up...but everytime i flash a new ROM, even if the imei is correct..it won't connect to network..so i need to take it to the repair shop and patch the modem. The guy who fixed is really pissed off at me
Should've taken it to samsung service centre(they asked 2500 in my local currency but the shop did it for 1500) Oh..the price i pay for being cheap :/
Sent from my GT-N7100 using XDA Free mobile app
update : i don't have to go to the shop anymore...i do it at home. the patched modems created with modem patcher v2 work fine. everytime i flash a rom (always stock) the imei stays correct but the "emergency calls only" appears. PC Odin doesn't let me flash the patched modem for some reason. so i root the phone and install mobile odin and flash patched modem with it...and voila!! everything works just fine! i'm running 4.4.2 ....hope this process will also work when the lollipop update arrives.

I9300 IMEI / Serial Number Wiped after upgrade

Hi there I have a I9300 (International Version) of S3
So I'm just getting straight to the point
I had bought a s3 from a private seller from ebay and it was running 4.1.2.
I have a bit of experience in using Odin and I had downloaded some UK BTU android 4.3 version from sammobile.com which I usually use to update my phone.
But today if went wrong
I never did root because I never did like it and never made an efs backup
I had flashed I9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5 file to my phone and everything went perfectly fine
BUT THEN!
I tried calling some of my friends and I noticed that my sim wasn't being recognised
It didn't take long until I realised that my IMEI number had been to some random 0049***** number (I had found out that this was generic and was'nt my real IMEI Number)
I had then checked the IMEI number on the back of the phone and it did not match what was said in my phone settings
I have now clocked that it was the 4.3 android which was screwing me up
I have never installed any custom roms .etc and have only ever installed official ones from sammobile
So why would my phone's EFS get f***ed up and I also did'nt do any in Odin like phone efs clear
My phone had also ran out of warranty so I can't play dumb either
I have researched and found that it is possible to edit the nv_data file.etc like on http://forum.xda-developers.com/showthread.php?t=1804117
I have also tried downgrading but now odin wont allow but probably has something to do with samsung (downgrading policy)
I have also NOW made a backup of my efs folder and my phone is fully functional but my IMEI AND my SERIAL NUMBER was changed
Be honest do I have a realistic chance of recovering my phone or would I have to shell out of repairs and if so how much would it cost?

I have unfortunately tried this and I have realised that some of the phone data in the s2 is different compared to the s3
Also just one question if I could downgrade back to 4.1 would I get my IMEI back?

Sorry for the wrong link.
Maybe this?
- Try to reflash latest 4.3 for your country (this will most likely solve the issue if your efs is not broken)
- You can also try the methods in the link (there are many)
In my limited experience; downgrading to 4.1.2 after 4.3 gave me bootloop and it can't read efs2 (from 4.3)

[Q] Flashed Stock Rom 4.3 via ODIN, can't make/receive calls

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.

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?

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.

Restoring IMEI after corrupt EFS

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.
So if you need help, i can help.

Hey mate,
Want me to PM you?
Thanks
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

sch-i545 Baseband unknown, IMEI Null

Hi all
Just want to say I've been using XDA for a very long time, back to the OG Droid days, and wanted to say thanks right off the bat to those who are more skilled than I and for the help posted.
I recently aquired a sch-I545. The phone is in excellent condition, the only issue was that it was missing the IMEI, it's on the phone sticker, just not software. The baseband is also unknown. I knew this when buying it, that's how I got it so cheap. I figured that the guy had tried to flash it, and just didn't want to own up to it.
However, I have hit a wall. I've tried flash a stock rom on it so that I could root it and gain access to the EFS folder and see if I could modify anything. When I did, even though there was an EFS folder there was nothing to modify. I then heard about flashing a modem.bin to see about correcting the baseband and possibly the IMEI. Though I was rooted I didn't have a custom recovery, as of yet. I went to install TWRP via Odin and it starts the NAND write and then Fails.
So at my wits end I took it to a local shop, hoping that they might have better experience with this and I got the phone back today, with the Software Update Failed screen. I asked what was up, and was told that since someone tried to flash it, they erased the IMEI and they couldn't correct it. Asked why they gave me the phone back with the screen and was told that they too tried to flash with ODIN and it failed.
Luckily I didn't have to pay anything, but I think they just borked things up to and didn't want to own up to it lol.
SO....here's my question.
Can I flash a stock, or rooted ROM to this puppy that already has an IMEI and Baseband, and then Modify the IMEI to the correct one that is stickered on the phone? If I can, what search parameters should I look for? And is there a particular version of ODIN I need to use?
If I can't flash a ROM that already has a baseband and IMEI, how can I go about correcting this issue if ODIN doesn't want to write a custom recovery?
Thanks
You'll need Odin software and the correct factory image for the phone. There are a couple different builds so make sure to get the right one. If it's an MDK device and has never taken an OTA you're in luck. It can get TWRP on it after following the process. If it's later than MDK no TWRP. Search here and you'll find a thread explaining how to do it all.
Is there any way to tell if it's MDK after I flash the correct factory image? I have no clue if the person before updated via OTA.
