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

Posted By MrW0lf 20:20 64 , , ,  

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)

  32. I have a SIII GT-I9300. IMEI was corrupt after a failed rom upgrade. Been trying for months to fix the problem. Don't have access to a "box". Have done lots of rom writes to see if it would fix IMEI. No joy. Tried your Modem file and it worked first try. Thank you very much!!!

  33. Working With S3 Thanks

  34. I don't know really how to thank you, after I downgraded my SGS3 from 4.3 to 4.1.2 I lost the IMEI and it gave me a fake one, with this tool I succeeded getting my original IMEI back ... (A donation will be released soon :D) Thank you.

  54. 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. 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. 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. 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

    ReplyDelete

  58. Well, thank you so much.
    As far as i know flashing the latest FW won't fix thi IMEI issue.
    But let see as i'm about to flash UK BTU 4.4.2 I9505XXUGNG8.
