I know I should not post this thread because there are other threads with this problem.
Yesterday I was having issues with Sotmax_Ultimate_Stock_V23_XXUFME7_HD_AR ROM. It became laggy, pretty unstable bla bla bla so I decided to flash a stock ROM on my S3. After flashing I rooted my phone once again ( followed the chainfire guide CF-Auto-Root-m0-m0xx-gti9300.tar ) and went to sleep. After waking my I saw No Service and my IMEI went to 004999010640000 tho my serial number didn't change. Now I readed the whole forum and I only found the way to get back to original IMEI is to restore EFS Backup that you done. I never done an EFS backup. Everytime I was flashing different ROM I only did nandroid backup if something goes wrong and I would get bootloops or soft brick. How to get my Network working again so I could make calls and get my IMEI back?

After flashing a modem I had no network. I've checked and I have no IMEI. When I type *#06# the box is just empty.
I already restored an EFS backup I've made, and the EFS folder seems ok.
Also, the modem I flashed was the stock one.
Do anyone have an ideia of what can I do to recover my IMEI?
I think you have installed the wrong Modem driver, try to get the official one from other sources and try again.

Nope, it is the correct stock modem. I also reflashed my previous one and it still has no IMEI.
Modem has nothing to do with a lost IMEI .
Restore backed up EFS and or factory reset .
Fails try a stock rom flash .

Yeah, but I only lost IMEI after flashing the modem. I had flashed modems before (even this one) and never had problems, so something must had gone wrong.
Already restored a backed up EFS.
If I don't find any fix I guess I'll try a stock rom flash...
Type *#1234# and see if baseband is unknown. If so then flash another modem.
Another thing to check is that if stock samsung dialer is not working imei will say null.

If imei and serial number are not corrupted. Check your APN settings. You may want to flash stock rom to see if that works. Backing up efs folder highly recommended.

Try Ariza patch. Search XDA and downlowd apk. You may need to install the patch every time you update the software.

Dial *#06# in your phone's dailer and if your IMEI matches the IMEI on your phone's box or under battery then its something else.
If it says something like 0049xxxx or null or 0000... Your IMEI is corrupted.
In the case of corrupted IMEI you must have a backup of your EFS folder in order to restore it. If you have backed up your EFS then you're safe. If not.... Only Samsung can fix it for you, provided you have warranty left.
I had the same problem.. my IMEI changed to 0049xxxxxx by installing Custom Rom. Got it fixed for free by Samsung PM me if you want to know how.

I got this phone earlier this week I rooted it yesterday made a backup on titanium and clockworkmod I installed the rom and I had mobile data and i was stuck on emergency calls only. I flashed back to stock and the same issue is happening. I tried to flash a different rom and that time the setup wizard FC'd. I have no idea what I did wrong, this is the same stock rom and what I used to flash to my friends phone and his works fine. I have just checked what the phone thinks it's IMEI number is and it's different to what it says on the phone (behind the battery). I have tried to restore my data from titanium but its saying I never made a backup in the first place.
Any help would be greatly appreciated, this isnt the first time I've flashed a rom or rooted and I haven't done anything differently but somethings gone wrong and I'm stuck.

If you don't have a efs backup than its a trip to the service center.
If you have searched and read than you should have made this treat.

Hello lads. I have really really big problem with my I9300. I upgraded jellybean from 4.1.2 to 4.3, everything works perfect, but one main problem appears, I can't call, and receive phone calls. My samsung says that i'm not registered on network. I tried to install modems I've rooted device, and nothing happens. Today I decided to downgrade 4.3 to my previous 4.1.2. And surprise surprise, same problem Not registered on network. By the way my IMEI is normal. What should I do next? Any advices? Thanks

Hi.
Check for your Serial Number.
Go to, Settings, More, About Device, Status.
If it's 0000. It's corrupted. Also check for Baseband sometimes it shows unknown.
You have corrupted your EFS.
Backup your current EFS before you do anything from this point forward. You can try using PhilZ CWM.
Best bet is try to flash latest 4.3 Rom using Odin.

Same problem here. In my case, the problem is slightly different. the phone was a XXEMG4 that i had to downgrade to unlock and consequently recover IMEI. After recover IMEI (I didn't make an efs backup…) i upgrade to 4.3 and can't register on network.
I've been making a lot of research on the subject and i understand i should made a backup of the efs, but i didn't…. My question now is:
Is there any possible way to restore the efs module in v2 permanently, so we can flash another rom without losing it ?
thats the 1.000.000£ question for me

Your efs is corrupt, patched modem may enable it to again be read but will have to be patched reach time you flash new firmware/modem.

Makes no sense, you can restore a backup at any time. If you've already corrupted efs without making a backup then things can only get worse if you don't start making backups before you flash.
Lads. Now my IMEI and serial looks alright, but there's still one but. Internet is working with my SIM card, but I still can't call and send messages. In status:
Network: Meteor
Mobile network type: UMTS
Service state: Out of service
Signal strength: -99 dBm 7 asu
What should I do now? By the way, I've tried to reset factory settings, restart couple of times, when I'm trying to register on network, device says me TRY LATER. Oh, and when I turning my phone on, and PIN shows, it saying that my SIM CARD IS LOCKED, EMERGENCY CALLS ONLY
Sim locked to network ask your vendor to unlock .
After having S3 for some months, I decided to update it to 4.3.
So I searched online and saw some tutorials how to root and install costum ROMs.
I read few tutorials to be sure how to do that and after all went good and the ROM installed, One problem has rised: NO SIGNAL!
so I wiped all and installed a ROM STOCK.
After that the signal came back "half way". It's showing signal bars but I can't call to anyone, even after calling to my provider...
I just don't know what to do. Please help

well these tutorial you've read were either very bad or you haven't read them correctly, because probably you missed the important step of the efs backup. see therefor the stickies thread or the thousands of similiar questions here in the q&a.

That is your backup flash with odin
( When you flashed a custom rom it probably backed up your efs some roms backup by default)
I would just backup your efs you have at the moment just in case you have problems flashing. You will then be able to return to how your efs is now even though it is not fully working..
Or try this app >> https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool <<
The phone has to bee rotted to use ktool?
I also understand from the link you did about the EFS that there are two types of base bands and if I have an efs backup that I did on V1 baseband so I can't restore it on a v2 baseband, so my conclusion is to get back to 4.1.2... correct me if I am wrong

good that you found efs backup
yes you need root. or you use the recovery philz touch to restore your efs (then you don't need root, but a custom recovery).
well samsung roms based on 4.3 need efs v2, so you have to go back to 4.1.2 to restore your efs v1 backup.
if everything is working again, I would suggest you to use oding to upgrade to 4.3, because then everything should be updated correctly (but keep your efs backup, and make another one, just to be sure)
then you can try out again custom roms based on sammy 4.3
So what is the best option to restore it?
Because before I tried (while 4.3 stock rom was installed) the flash it with Odin but Odin always crashed when I was uploading it to Odin.
With kTool I tried before but when I am clicking on the button it says that it restored but he didn't asked for directory, when do I need to put it?
The same story with phliz, I also tried with this and he don't asks for directory, only asking whan the ending if the file-tar to bin...

Where is this folder located? I can't find it
and does it for xTool and phliz recovery destinations for teaking the recovery from?

I found the /efs. I dind't know that I need to use root explorer...
I exchanged the files with my back up and suddenly instead of 0049 IMEI I got 0000 IMEI.

Hmm... try installing another EFSv2 modem, then do the /efs copying part again.
Suddenly after so restarts, the IMEI got back
But... The SN now is 0000000000
You'll need to correct the permissions of the files you've copied. Try searching for someone who already did this and duplicate what they did.

Ok,
I tried something new. I flashed a new modem, backed up a full backup and then installed a costum rom 4.3.
the IMEI GOT BACK! And even the SERIAL NUMBER!
But I think the serial number is not good because he has 16 or 17 (I don't remember) digits (numbers and letters).
But still i have signal bars but can't make or receive calls he says: "No registered on network"
For the finalle, I tried ARIZA patch but he Is stuck on 0%...
here I stopped, I really don't know what to do.
Don't use the Ariza patch once you've got your IMEI and SN back. Maybe try flashing a new stock version of Android with a EFSv2 baseband so as to not go through the copying fiasco.
