Hey guys, just registered to post about a problem I've encountered with my galaxy s3 i9300. I rooted my phone and flashed cyanogen mod 10.2. After this everything looked good but then I realised that my mobile network wasn't working. I searched around the web for a few weeks now and found out that the problem was my imei number. My IMEI number changed to 004999010640000 from the official number under my battery and I couldn't find out how to restore it. Apparently I should have backed up my EFS folder before the rooting process but I didn't know.
Is there any way to restore my current IMEI number back to the official IMEI number without the EFS folder?
I'm new to this sort of stuff and I would really appreciate it if somebody could tell me something about this problem..Thanks in advance!!

ill share my experience with you, but i can't guarantee that it will work for you. I was on a Samsung 4.1.2 ROM. I flashed a Samsung 4.2.2 ROM, which had a modem change option (cant remember which one i selected). The result was my IMEI being change to 004xxxxxxxxx as well. I reflashed the 4.1.2 ROM, my IMEI went back to normal. Then i reflashed the 4.2.2 ROM and selected "do no change modem". My IMEI stayed normal when i reflashed the 4.2.2 so i assume it has something to do with the modem.
You change yours by any change?
Don't know if this will help you, maybe someone with more experience can.

Hi guys,
I would be grateful if anyone can help or point me in the right direction to resolve the IMEI issue with my P7500.
I have no idea why the IMEI number on tablet (IMEI number: 0049....00, as provided by about->status) is different from the IMEI number written on the back of the tablet (first few digits 3577...). Please note that the IMEI number written on the back of the tablet and on the original box match!
My tablet is still under warranty and I have only flashed custom ROMS and used odin to flash original ROMS.
Any ideas or suggestions please?
Thank you

Did you backup EFS folder? after rooting it's a must.
Try to flash original rom for your tablet, and if your imei is the same(0049....) only service center will rewrite back your original IMEI)- but this is not cover by your warranty....
Hey,
I have a question regarding serial number. I am currently using Official ICS 4.0.3, CSC = COA, the IMEI is displayed correctly, but it looks like the serial number that is read by Android is totally different than what is displayed on the sticker on the back of the phone. It is something like 0019...
Does this mean that the /efs folder is screwed up? Note that I used various ROMs in the past: DarkyROM, ICS 4.0.4 ROMs (where serial number was displayed 0000...), Samsung Jelly Bean Leak, CM9 and CM10 - based ROMs. When I revert, I always flash an Open Europe full wipe Gingerbread version (XXKL1) and then incrementally update to the version with my corresponding CSC.
When I connect the phone to Samsung Kies, it is able to read the phone, it says this is the latest update (4.0.3), but I kinda find it hard to believe so I am curious whether it's S/N screwed up. Also, when I looked on Sammobile.com, I managed to find downloadable 4.0.4 OTA files for Cosmote Romania (COA).
Some threads mention flashing bootloaders or flashing official ROMs. I already did flash official ROMs but never dealt with bootloaders so far, so before I do anything, I would like some help if anyone can provide me with some specific information regarding this issue.
Furthermore, this may be important for future potential warranty service and this may help other people with similar issues.
Thanks a lot!
You have a question?
Isn't there a special section for that?

Yeah, I noticed after, sorry, if the Moderators can move it, that would be great, anyway if you know the answer, that would be great as well.
hi
same here, also wondering why the S/N on the IMEI Sticker on the back of the phone is diffrent than the S/N that show up under Settings>About Device>Status>Serial number. the imei is the same. (GT-9100, 4.0.3). there is another way/code to find the S/N ?
I noticed that N7100 and GT-I9300 IMEI and S/N that displayed on the back is exactly the same as the android shows.
thanks in advance
i have Samsung Galaxy s2 gt-i9100(rooted) and suddenly my network signal was missing. and i dialed *#06# and display no imei and unknown baseband . so how to solve that problem?
gt-i9100
android version - 2.3.4
baseband - unknown
kernal version - 2.6.35.7-i9100xxkh3-cl479037 [email protected] #2
No EFS backup ? Try flashing some stock roms. If that doesn't work, service centre or local mobile repair shop; they have equipment to write the IMEI back to the device.
Yes sir i have i have tried to restore but it didnt work
neddinary
Sir give links to flash rom
plz
Samfirmware. No, I'm not going to give you a direct link; did your last slave die of overwork per chance ?
same problem
what firmwere should i download if it dosnt show up any baseband version????
Did anyone gotta solution?? :crying:
Try all the firmwares for your country/carrier (not 4.0.4 though, just in case you flash & forget then do a factory reset. If you've flashed a couple of those & your IMEI hasn't returned, it's fairly safe to say it isn't coming back; take it to a local mobile repair shop, many have the equipment to re-write the IMEI to the device fairly cheaply.
Did you manage to sort this? I was asked to look at a friends S2 which was showing no IMEI number, and I managed to sort it....

Spill the beans then; what did you do to fix it ?

Ah.... this fone was completely stock, still running Gingerbread 2. whatever!!
So.... all using Odin....
I updated-no joy
I rooted-no joy
I flashed newer custom ROM-no joy
Then, I tried flashing Stock 4.1.2, and away it went!!
IMEI number replaced, fone now working, friend well impressed!!
The files are I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar.md5
I'm not sure how to post a link (perhaps someone could show), I got them from YouTube, but have them if anybody needs them.
But if you Google for that, and you're on UK S2 I9100, you should be fine!!
Hope this helps some people, please bear in mind the usual : "I cannot be held responsible for any damage caused...."

Read this thread: [REF] IMEI / EFS - Know this stuff (i9300) - including "no network"
If you don't have an EFS backup, and you already tried to odin stock 4.3, then you should take it to a phone repair shop.
You already got the correct answer in the last thread you started, don't start duplicates.

Please do not open multiple threads for the same issue. Thanks.
2 months Back: My brother in the name of rooting and making my galaxy tab s3 better he bricked the tab. I wasn't sure which firmware he was on and the ODIN Singapore firmware was not accepting so I used the latest firmware from the UK and restored my tab.
Present: I suddenly wanted to check the IMEI out of the blue. When I checked I couldn't find the IMEI in the phone settings so I installed my phone info app from playstore to see if it is picking up IMEI. To my surprise, I can't find IMEI there too. How to restore original IMEI?
Tab model is SM-T820.
If I were to leave it out just like this would there be any issue?
Would love to hear a solution.
