Step To Install firmware updates for Samsung Galaxy S3

 1. At first, make sure you have installed the drivers correctly on your PC.

2. After download files, you need to extract them all in one specified folder.

3. Now, Switch Off your phone completely and start your device into Download Mode by pressing and holding the ‘Volume Down + Home button’ together, and then press the ‘Power button’ till you see the Android Construction logo. Once again press ‘Power Up’ button to confirm.

4. Open “Odin.exe” and connect your phone in download mode itself. If your phone is connected successfully the one of the ID:COM boxes will turn yellow or green in color.

5. Now connect Galaxy S3 to computer with USB cable in Download Mode. When Odin detects the device and a pop-up message reading "Added!" appears on screen, the ID: COM box will turn yellow with the COM port number.

Note: If the Added message fails to appear, then try re-installing USB drivers or changing the port on computer.

6. In Odin, click on AP button and select the firmware file (I9300XXDLJ5_I9300ODDDLI7_INU.tar.md5) with .tar.md5 extension.

• Click on 'CP/Phone' and select file named 'MODEM'. 

• Click on 'CSC' and select file named 'CSC'. 

• Click on 'PIT' and select the .pit file.

Note: Ignore the last three steps in Step 7, if the file is not found.

8. Now choose Auto Reboot and F. Reset Time checkboxes in Odin. Leave the Re-Partition option unchecked.

9. After ensuring that Step 7 and Step 8 are done correctly, hit the Start button in Odin to begin installing the firmware.

10. After the firmware is installed, a PASS message with green background appears in the left-most box at the top of Odin. Galaxy S3 will then reboot to the Home screen. It is now safe to disconnect the USB cable and remove the phone from computer.

Galaxy S3 is now running I9300XXUGND2 Android 4.3 Jelly Bean official firmware. Head over to Settings >> About Phone to verify the firmware installed on the device.
