How to Fix "Not Registered on Network"/Wrong IMEI for Galaxy S3/S4/Note2

Posted By MrW0lf 20:20 98 , , ,  

This tutorial will learn you how to fix "not registered on network", wrong IMEI for :
  • Samsung galaxy S3 GT-I9300 model ONLY.
  • Samsung galaxy Note 2 GT-N7100 model ONLY. 
  • Samsung galaxy S4 GT-I9500 model ONLY.
  • Samsung galaxy S4 GT-I9505 model ONLY.
Before starting :
  • Backup your important data first just in case of this process corrupt your data.
  • Download and install Samsung mobile driver (Skip this if you already have Samsung Kies)  (Link below)
  • Download MODEM.tar.md5 file then unzip it only one time (Link below)
  • Download Odin3 then unzip it (Link below) Disable the antivirus software, Close Samsung Kies and disconnect any device connected to USB ports on your computer.
Flashing instructions :
1- Run "Odin3" as administrator, Click on PDA button and navigate to Modem.tar.md5 file that you extracted.
2 - Shut down your device and make sure your device is completely off
3 - Put your device into download mode by pressing and holding (Volume Down + Home + Power) buttons
4 - Press Volume up to continue
5 - Connect the device to your computer by USB cable and wait until you get a sign in Odin (ID:COM section) and "Added" in message box.
6 - Make sure re-partition is NOT SELECTED [Very important]
7- Click Start and wait a few seconds until you see "PASS!".

Notes :
  • Do not disconnect the cable or turn off the device while flashing
  • I am not responsible if something wrong happened to your device (use this AT YOUR OWN RISK)
  • Install Samsung Mobile Driver or Samsung Kies if you don't see a sign in Odin (Step 5)
  • This process takes maximum 1 minute
  • In some cases this won't fix the wrong IMEI or "not registered on network" message
  • If your device stuck in boot loop after downgrading, factory reset your device from recovery mode (Vol up+Home+Power)

    Mr Wolf I've got the same problem.
    How i got my IMEI null/null & Baseband unknown,
    I've had flashed the Pheonix Rom for my S4 I9505 & it was smooth and working like a charm and after 2, 3 months my phone reboots itself and i've got no service and my IMEI null. :S
    "And then again Sometimes my phone used to reboots itself and i've got my IMEI back again."
    And that goes again n again.
    and then i've flashed my device on Stock Firmware 4.4.2 and STILL THE SAME.
    Please Reply ASAP.

    ReplyDelete
  55. MrW0lf23 January, 2015 12:02

    STILL THE SAME. you mean rebooting or IMIE?
    After flashing stock FW did you factory reset, Flash the latest FW for your device cause restarting problem sometimes happened cause of some updates.

    ReplyDelete
  56. Haider Saroya23 January, 2015 15:31

    Rebooting.
    Yes i did Factory reset plus wipe cache partition.
    But this didn't fix my problem either.
    My device reboots usually and my network signals come and go. (IMEI null/null to 1/01)

    ReplyDelete
  57. MrW0lf23 January, 2015 23:33

    Flash the latest FW file for your device model
    If it doesn't fix it try this http://forum.xda-developers.com/galaxy-s4/general/fix-reboot-crash-problem-ng6-root-t2921584

Then i had no hopes and did'nt know what to do. Then i made an wipe/factory reset + wipe cache partition and IT WOOOOORKED :D:D:D:D:D

    i'm not sure whether your instruction or my proper workings made this. But it doesn't matter. The main thing is that your solution was the best and easiest and it solved my problem. Don't matter how much i thank you it is not enough.

    My phone's imei was gone after rooting it.... i tried alot of other guides but this seemed to be the only one that did the trick.

    I have simply followed all these steps as discribed above and flashed the ND1 file to my note 2... when odin said complete, my issue was fixed

    btw: when using odin with the note 2, turn off auto reboot, else the phone will reboot already while it is still flashing... just reboot it manually when it says PASS (only pass, no RESET or annything else)
    good luck

    man i was having the same problem but this is the simplest way to solve it .

    1. Download and Extract: Odin3 3.04.zip – 457.11 KB to your PC if you don't already have it.

    2. Download and Extract: Param_Bin_I9305.zip – 612.14 KB to your PC.

    With your Phone Switched Off, press and hold: 'VOL DN' + 'HOME' + 'POWER' to enter Download Mode.

    Connect your phone to your PC via USB Cable and start Odin.

    Check your phone is connected by seeing if a COM Port in a Blue box is present under ID:COM.

    Press the 'PDA' Button and select the 'Param_Bin_I9305.tar.md5' file you extracted from the Zip Archive earlier.

    Press the 'PDA' Button and wait for it to finish flashing. If successful, you will see a Green Box with 'PASS!'.

    Wait for your phone to reboot then go to your Dialer and press: *#06#. You should now see your IMEI and your Data Connection will be back.
