    I really searched about my issue all over internet and tried everything, include ARIZA patch, 9 steps recovery and etc.. Please, someone help me.

    So here's the deal. I bought my SGS3 from second hand, everything worked perfect. One day I noticed a little lag when you unlock phone (i mean press lock button on the side). It took about one sec to phone response. I thought it was old firmware fault, so I wanted to make an update. Phone was rooted, so I couldn't make it through Kies or android. I was a noob at these things, so I googled and saw that I could make an update via Odin. So I did. I downloaded official firmware from, flashing went good, phone turned on and everything worked. BUT! I couldn't acces my network, 3G, make calls and sms etc. (and everything what is accesed via sim card). After hours of googling, I came with conclusion, that my IMEI is not original. unfortunately I haven't made an EFS backup. Then, I spent about week trying to work it out. I tried, i think, all tutorials on the net.

    Could someone try to help me?

    Now IMEI starts with 0049..
    and SERIAL NUMBER is all zeros 0000000

    Welcome Trewit!!
    Sorry about your issues here and I don't know if I can be much help, but what carrier are you on?
    And are you sure that you flashed the correct firmware?

    I would assume that after the firmware flash, you are now unrooted?

    Thanks for replies guys. I use TELE2 carrier, I'm from Lithuania. I think I am sure, that firmware is correct. I downloaded SEB (Baltic) region. Currently now, Im rooted again, because I tried some tutorials.

    I am sorry to hear this but I'm afraid you may have an insurmountable problem without and EFS backup. There may be a remote chance that the phone was previously equipped with a custom ROM that made an EFS backup prior to flashing - have a look on your internal SD partition, look for efs_backup folder or something similar (if you haven't already got a file explorer get one of the free ones from Play Store to find the folder).

    Other than that I think it's going to be impossible to get the IMEI back. One minute hope that may be lurking around springs to mind; over at XDA developer forum I think I've read about someone manually changing a database (xml) record in the system partition manually with the phones' relevant IMEI data (presumably from under the battery). Sorry that I can't offer any more help - good luck!

    Do you remember what ROM you were using before you went back to the official firmware?

    I have EFS backed up but id have no idea how to restore it if anything went wrong. Anyone got a guide?

    Since you're on an S3 K-tool from the Play Store will work fine. Just run an initial backup with and save it to your external SD. If necessary, you can restore from that in the future. The alternative is efs backup pro, which you can pick up over at XDA forum and which is really simple to use in Windows. You don't even have to go into download mode to run it - just connect your device and wait for it to be recognised, then run the executable (*.exe) and follow the on-screen instructions.

    P.S. just found this which is a definitive guide and easy to follow (works pretty much for all recent Samsung Galaxy devices - - courtesy of Droidviews.

    Hey, thanks for a good advice, I appreciate that! Although, I just came with compromise and sent it to nearest phone repair company. They fixed it after 2 hours, so they obviously did it with z3x or octopus box. They charged me for about 15 euros. thanks anyway ;)

    I bought it with official firmware, as I said, from second hand

    Just remember, next time you flash any ROM ... backup EFS!!!

    Have identical problem. Does anyone not have a EFS backup that can be used and then I can maybe edit it and change to my own IMEI number? Is this possible?

    This is a good idea and worth trying first, had the same issues with a Note 2 after an official FW update, only rolling it back sorted it.

    Weird thing was the Note 2 was fully stock, either O2 or Samsung (I'm guessing O2) dropped a bollock on that one.
