Do you have EFS backup ??
You can restore it if you have and your phone imei would be restored.

One us a bigger text two read the multiple identical posts for a solution .
The basic answer is to restore your backed up EFS folder as that is the first step .
Second try factory reset or flash stock firmware .
Fails then its a service centre repair .

[Q] SOLVED Phone stuck on emergency calls only?! (Blocked IMEI)

Yesterday on my way to my cabin my phone stopped connecting to network. I can't call, send messages and can't use mobile data. I tried to which sim card with a friend, but that didn't work. Is my phone damaged or is it just an error on the network?
Sent from my GT-I9300 using WIFI
EDIT: After flashing Xperianze ROM my phone had got the IMEI of a stolen S II in Kenya. Since the phone which had this IMEI was stolen it was blacklisted. So if you find out that your IMEI is changed simply use Kies to flash stock. Then your orginal IMEI is going to be restored!
Use these two links to check your IMEI:
Link 1 - http://swappa.com/esn
Link 2 - http://www.imeidetective.com/
Do check on both sites!

No cellular network "Mobile network not available" !!!

I have galaxy s3 i9300 and my problem is no mobile network on my phone so i can't make calls or even open mobile data.
What i did:
I was using CM12.1 android 5.1.1 everything was ok for months but i faced a problem after that time which is "can't open mobile data" i thought that the problem is from the Custom ROM which is not stable, so i decided to downgrade to the official/original stock ROM android 4.3 Smamsung Career, but the issue still existes or it became more deep i don't know what's wrong with it. there's a signal of network connection but when i call it says "Not registered on network". I did the network settings and search for operators automatically but it didn't work also. at the end (currently now) i decided to back to the custom ROM but the problem still there so i don't have no cellular network or data mobile plan.
What i think:
I think that the EFS partition touched Note: i still have the IMEI
So please can anybody help me?? i'm reallyyyy neeed heeeelp

I was wrong my s3 was bricked and it is not the EFS partition that has been touched "beacause the IMEI still there" but the problem is that the Serial Number i have it BUT when i updated to cyanogenmod the OS gives me a wrong serial number so that's why it told me "Not registered..." so i'm needing to inject the true SN in my device. So how can i do that with Z3x Box? thanks

Have u tried restoring With Samsung Smart Switch
No i have not tried
Try restore it with Samsung switch, if not you'll have to find a way to change the imie no. Back to its original otherwise your network won't register the phone to you.
I got the same problem... I guess the IMEI has been altered or the update failed... i tried to downgrade to 5.1.1 but impossible. :/

This problem occurs with phones that had imei changed, only way to fix it is to write certificate again and fix baseband, who need this can contact me via pm, I have professional equipment to do this remotely

Wrote you a PM
Why inte wolrd does the imei got changed? And how do i fix it. Had a full backup with twrp saved on onedrive, phone and main pc all where brocken even tough i usef the backups several times.
Twrp could autobackup efs everhtime its so small guess they dont care about their people. Yeah i know my own fault but would be obe line of code for them.

Please check if imei and serial number are both shown when you tap *#06#, if you have both seems your phone got blacklisted on imei from software, only writing a valid certificate will solve your problem

I'm having this problem too. I see the imei and the serial number. Does this mean the phone is blacklisted?

I'm also having trouble. I bought my phone out of an independent shop, on purchase they told me it's not possible to update, and basically got the phone at a bargain. But, I have been doing digging. My guess is they have bought a blacklisted phone and flashed a cert to fix it. So my question is.. what is a cert? Does it contain the imei info, and is it tied to the software version the cert file? And will it ever be possible to flash a MM rom. I have tried and it won't go past the Samsung logo, only 5.1.1 Roms work :/
