Important Reminders before Flashing Galaxy S3 Firmware/Stock FROM

- Make sure that your Galaxy S3′s battery is fully charge.
- Stock ROM packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc.  before flashing no-matter if it is Full-WIpe or Non-Wipe,  just to be safe and ensure that your stored data are in  safe  if something went wrong during the flashing process.
- Remember or back up the APN settings of your device. ( This only done if you try to install the other region stock ROM.
- Use a PC or laptop that runs in Windows OS, with a good and perfectly working USB serial port.  Odin will not work on MAC OS.
- Use the supplied USB cable for your Galaxy S3.
- Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’.
- Do a “Hard Reset” if you have a lot of 3rd party applications installed from your phone, this is useful to gain a smooth flashing. (Just make sure that you already back up all your important files before resetting your device.
- Ensure that KIES is closed and not running in the system tray! Kies will interrupt and doesn’t like Odin, it will block you from flashing.

Step 2: Extract the downloaded I9300XXUGNH4 stock ROM

You need to extract the downloaded file which is packed in zip or rar files, so that you’ll get the tar.md5 file.

Step 3: Run and Configure Odin

Run Odin downloader Odin3_v3.07 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked, only  the ‘AUTO-REBOOT and ‘F.RESET TIME’ checkboxes are both remained checked.

Step 6: Reboot your Galaxy S3 into Download Mode

To reboot the Galaxy S3 into  download mode , you need to turn the power off.  After it completely shut off,  just  press and hold the Volume Down key,  Home button and the PowerON/OFF button simultaneously.

You should then prompted into a warning screen and asking you  to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Step 5: Connect your Phone to PC or Laptop

Once you already reboot the phone in download mode,  simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin.

Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Step 6: Load the binary .tar.md5 file

If the stock ROM is pack in One .tar.md5 file only the PDA, CSC and Phone modem are already included to it. Now, you need to just simply click on the PDA or AP button, then browse to the folder where the .tar or .tar.md5 you have previously extracted and then select and load it.
Just like this image below, I used Switzerland unbranded Galaxy S3 stock ROM on this guide, so it came as “ I9300XXUGNH4 _I9300AUTGNH1_I9300XXUGNA8_HOME.tar.md5″.

Build numbers varies on each product code, specific geographical region and network CSC (Consumer Software Customization) codes.

Step 7: Start Flashing or Installing the stock ROM

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finish.

Step 8: Watch out for the word PASS!!

When the Stock ROM installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s to remove it from PC or laptop USB connection.

Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
You can also do factory reset by dialing *2767*3855#.
Check and reconfigure your APN settings when data networks connection issues encountered. This only happens if you installed other regions stock ROM.

Possible errors that you may encountered, this is based on my own experience while flashing stock ROM on Samsung Android devices. These are just a few hints on how to resolved it.

Q: I got an error message that says “Set-up connection Failed” ?
A: 1. Check your USB connection from the phone to PC,
2. Connect to another PC USB port
3. Check and try to another USB cable
4. Re-install the USB driver.

Q: Odin just suddenly stuck in the middle of nowhere while in flashing progress, It isn’t responding at all?
A: Check for possible program that might interrupt the process, like disabling the anti-virus and closing any running programs.
Try to use another PC or laptop,

Q: I experienced bootloop or the phone just stuck on Welcome Logo (phone always stop at bootanimation) and it won’t boot normally?
A: You can fix it via recovery mode option, do this:
Boot in recovery mode
1. Press and hold Volume Up, Home and Power button.
2. Use volume keys to select, Up and Down and Power or Home key to select the option
3. Select Wipe Data/Factory Reset using the Home button.
4. Next select the Wipe Cache Partition
5. Lastly, select Reboot System Now to reboot your Galaxy S3 in Normal mode.

Q: My Galaxy S III is now soft-bricked, what should I do then.
A: For 3 years, never been happened to me soft-bricking my older phones using Odin, I was once got soft-bricks using ROM manager. But if somehow this happens to your device, here’s how.

If you can still access the phone in Download Mode, then you can recover it by repeating the flashing procedure again.
If not, that’s seriously bad. The only option is to send it to your nearest service center. Folks at service will recover it by forcing to re-flash the firmware via JTAG.

That’s it! you have now learned how to install Samsung Galaxy S3 stock ROM. You can use this procedure again and again, using any future stock ROM that only match with your device. But remember DO NOT use this method to downgrade your Galaxy S3 to any old firmware since the latest 4.3 updates has a new security policy guidelines which prevents you to downgrade. All other questions and suggestions are most welcome, just let me know by leaving a message on the comment form below.
