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

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)

  29. 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!!!

  31. 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.
