[Q] IMEI problem keeps coming back - Galaxy S III Q&A, Help & Troubleshooting

Hey there people, first I wanna thank you for great community.
So I flashed a new rom (like i do every week ), of course I always have an efs backup (ktool and ARIZA).
this time after the phone rebooted the IMEI just didnt work,(exist but doesn't work), I've been contacted with the carrier and send the phone to repair.(and flashed a carrier stock rom of course).
they said the IMEI is "****ed up" and they changed it with JTAG, don't know about board switching.. they gave me the phone with stock rom so I flashed a new one, this time when I did the phone just gone back to the old IMEI (the one that doesn't work), I gave it back to them and they changed the IMEI again.
now I would like to flash a new rom and I dont want it to get back to the old IMEI..
you think if I'll back up the new IMEI and then flash the new rom (the IMEI will just go back to the old one) i could just restore it?
or is there any way I could flash a new rom without it would go back to old IMEI ??

Instead of bumping posts go to the service centre .
Your question and what's happened is beyond my understanding .
Only your carrier / vendor / Samsung can lawfully change an IMEI .

I know that, and I did.
I've been contacted with the carrier and send the phone to repair.(and flashed a carrier stock rom of course).
they said the IMEI is "****ed up" and they changed it with JTAG, don't know about board switching
now I have a stock rom and I'd like to flash a new rom, don't want it to go back to the old IMEI

Two choices one flash new rom or two dont flash new rom .
You say the service centre changed your IMEI so you now have a new IMEI .
jje

yes they did. I have a new IMEI, one that works but they game it to me with stock rom, I'd like to flash a new rom, and every time I do.. the old IMEI is being restored, my question is if I'll back up the new IMEI and flash a new rom (the old IMEI will come back) I could just restore it from back up?
I didn't find someone with the same problem

What JJEgan is trying to say, I think, is that talk of changing IMEI is taboo in these forums. You would be better off asking your service centre about the IMEI reverting to the old one after some time. Not about the custom ROMs of course.

Yes in a way IMEI is not a topic that can go to far .
Real reply is the IMEI has legitimately been changed the user is looking for another user with the exact same situation i guess . But their is none so he bumps and bumps posts .
Why the f*** would old IMEI come back if its been legitimately changed .
So as i said flash your rom or go back to the service centre to clarify .
END.

004999010640000 again
how can fix yhis problem?

Restore your EFS backup. Lots of threads on here that tell you how to do this. No backup ? Then you have a fairly serious problem.
i dont have backup
No backup eh ? As I said, that's a problem. OK. I assume you haven't rooted the phone or put a custom rom on it & are still running stock firmware ?
If you are still running stock/haven't flashed anything, send it in for warranty service. No point taking risks around losing your warranty through flashing things now.
If you have rooted the phone/been flashing non stock firmware on it, there are several apps on Google Play which claim to be able to recover your EFS/IMEI, they might be worth looking at.
There are also many threads on here outlining methods you can use to try and recover your EFS/IMEI (do a Google search & append XDA to your search terms).
If none of these work, you can contact a member on here called Odia who might (absolutely no guarantees whatsoever) be able to recover it for you (for a small donation). But contacting Odia should be your final step as I doubt he'll even consider helping you unless you've tried everything else first.
Contact odia or go service center

[Q] flashing rom changes imei suddenly

Hi,
I have flashed about 50 different roms on my galaxy s3 and never had any problem with it.
Now suddenly when i flash a new rom i get the dummy imei 0049...... and i get blocked by my cell provider.
I flashed the stock rom and this helped to get my original imei back. So i taught well i can flash a new rom now maybe something went wrong. But again i got the dummy imei. So i flashed stock again and backed up my EFS. Flashed a custom rom and restored my EFS but i still get the dummy imei.
I really don't know what to do now. How can i flash a custom rom and keep my normal imei.
Already tried different roms and different android versions.
You were lucky the first time you switched to stock your imei got restored. You should've backed it up before hand. Refer this , it will help

From CM 10.1.3 back to stock ROM, IMEI failed

Hello!
Today I decided to go back to the stock ROM of Samsung S3 (international).
So, I downloaded the original from sammobile :
http://www.sammobile.com/firmwares/3/?download=16458
Went into the Download mode of my phone:
With Odin3 (v3.07) I loaded the .tar.md5 file which I just downloaded. (by the PDA ofcourse).
Then my phone restarted and just follow the steps as you just get your new Samsung S3, like account configuration etc etc etc.
Did the tutorial to reset the flash/binary counter, just worked.
After this, I was planning to install Whatsapp again,
THEN noticed I had no network signal , except WiFi .
Probably there was no signal when the phone already got started.
I checked *#06# for the IMEI, and there it is.. the 004999xxxxxxxxxx / 08 .
So, I've checked some topics and tried a thing that should repair the IMEI.
But no success!
When I installed CyanogenMod, they didn't told me to backup the EFS folder (or I just didn't see that at all!)
So, I followed this topic:
http://forum.xda-developers.com/showthread.php?t=1264021
Didn't worked.
I'm root again btw on the stock ROM.
Then I noticed I've a backup of my phone BEFORE CM. Made it with the CWM itself, which I moved later to my computer.
So, I moved that one back to my phone. and when I go to CWM Recovery and select Restore
It says:
Couldn't open directory.
No files found.
So, checking for that error, someone came up with moving the backup files to
/data/media/Clockworkmod/backups/
Did not work!
What to do?
I'm questioning myself now, even if the restore is going to work, will the IMEI be restored too?
EDIT: Monday it will be shipped to Samsung.
- Back to stock
- Reset flash/binary counter
- Unroot
- Wipe cache and back to factory
Couldn't get rid of the 0049 IMEI and 0000000 S/N
I'll keep this post up to date when I hear something.
No CWM does not backup efs....I suggest you go here http://forum.xda-developers.com/showthread.php?t=2393289 because they will close this thread soon due to this question being asked many times before
I've seen that topic indeed, then I will put it back with flash/binary count to No , and the status to Normal.
Hope Samsung will fix it then when it just doesn't work.

Flash via CWM. If you don't want to flash it via CWM you can also extract "modem.bin" file and flash as MODEM through your Odin.

Thanks for your reply!
I've set everything back to stock and reset the counter/binary to No , and the rest Samsung official again.
Today I went to the shop where I bought my phone, and they're going to sent it to Samsung.
Forgot to mention here that my S/N is also 0000000.
Let's hope that they will repair it.
I've red a news article, that Samsung has a new policy.
They now also repair rooted devices and even when a custom ROM was installed.
I'll find out when I got a message from the service centre.
When I know something, I'll post it here.
Thanks again anyway!
Should have tried your modem.bin

Doubt that but just in case do let us know if Samsung reject warranty .

Will do :good:
Did you read the IMEI / EFS post on the general forum?
I had a similar problem... to make the story short before CM 10.1.3 I was on stock MG4, after CM I decided to go back to my carrier's stock ROM (needed to send my phone for repair, USB port was faulty) and I noticed the IMEI problem. What happened is that Samsung decided to change the efs format with MG4 (July 13th) so any rom prior to that won't be able to read the efs.
If your rom is prior to that then you need to flash a newer modem (MG4 or later) so it can work properly.

Yeah, I must have red over that... But I tried fixing it spending about 10-12 hours on it, cuz of searching and read it carefully.
I had no EFS backup, stupid that the CWM Recovery didn't backed that up , and of course, stupid of myself :silly:
I will now wait if Samsung is going to repair it under my warranty.
If not, they will probably call me about fixing it for a price.. (If the article isn't true about repairing rooted / flashed devices)
Update 15-11-'13
Phone is repaired under warranty!
They reprogrammed the phone and did a software update. I'm not sure if this is the 4.3.
Can pickup my phone monday, because the shop doesn't receive delivery on saturday -_- ..
But at least, it should be working fine now.

[Q] Same IMEI, different Serial Number

Hello people, I will try to simplify and be concise on the problem/doubt I'm having:
Last week I decided to spice things up a little installing a custom ROM (was in 4.2.2, rooted) and gave a 4.3 custom ROM a try.
First flash was successful but didn't get any network. Went back to stock and all was fine (of course I had made previous nandroid and EFS backup). Second flash, during installation in AROMA installer, I ticked an option to update to latest modem. After that, I could only get emergency calls :S, even if I flashed back to stock. IMEI was right, S/N was right (I think), but no signal. It was suggested it could be a modem problem, but I still didn't grasp all the EFS v1/v2 format thing, was growing desperate and didn't want to screw things up more than already did, so, lastly, took the phone to repair service where they used BOX and my phone is all operational now on 4.3 stock build: XXUGMK6.
I want to learn from my "noobness" and am tempted to flash a custom ROM. As you would imagine, I'm still quite traumatized with the past problem and afraid I might screw things up AGAIN.
Now, I've noticed that, while my IMEI is still correct, the S/N is incorrect (not the same as written on the back), yet, my phone is fully functional.
could that cause problem, be it with EFS folder or modem, if I decide to flash a custom ROM again? Aren't IMEI and S/N suppose to coincide with what's written on the back of the phone?
I hope I explained clearly and wasn't boring! My apologies if my english isn't perfect.
Many thanks in advance!
Take it back to repair service, get them to put the right serial number back on it. Also make sure they didn't used the patched kernel and modem, to test flash the latest stock firmware or OTA update, if network is lost you'll know they didn't fix it properly.
Don't flash things you don't fully understand, read all the stickies before to do anything.

Many thanks boomboomer for your reply. Before any flashing happened, I thoroughly read and understood at least an 80% of stickies, read all details about the custom rom and familiriazed myself with all main reference and guides threads. I've flashed custom roms on previous phones I've owned. The loss of network connectivity caught off guard and was looking for a definite solution.
So, I should flash latest stock rom before taking it again to service? what really happens if phone shows different S/N? again, thanks.

[Q] Is it common for an imei to get changed when flashing a custom rom?

I heard when someone flashes a custom rom, the imei gets changed, is it normal, and is there a way to restore the original imei without backing up the imei ? want to sell on swappa, but imei says it got blacklisted, even though i have the original box for my phone any help is appriciated!
The IMEI does not get changed at all.

Also, any discussion regarding IMEI cleaning, is not allowed. You will have to figure it out yourself or sell your device as is. Try calling your carrier.
IMEI does NOT get changed. What could possibly happen is it getting erased and set to 0.

That will never happen with flashing ROMs. It could happen with a messed up ODIN flash or messing around in the wrong programs, But ROMs never touch the IMEI.

Yes sir. I understand. Since the user seemed like a layman, I didn't want to use all these terms, and used the word flashing ROMs
this is what's happening to me and my friends, I'll list it step by step to be clear about it
1) Get phone from t-mobile
2) Roots phone because we dont care about the warranty (imei is still the ones that came with my box)
3) Flashes custom rom (goldeneye, vision, etc)
4) Phone seems normal but imei gets changed to one that is not mine and is also a blocked imei, not sure if it was flashing the custom rom that changed the imei.
Odin back to stock ROM. Or use Samsung Kies to restore the phone's stock ROM. (Wipe cache and factory reset after you restored to stock).
