Step 5: Now launch ‘Odin Multi Downloader3-v3.09′ software which you’ve just downloaded and extracted. As soon as you open it, the ID:COM section (located at top left corner) in it will turn blue. Also an Added message will appear in the message window. This will confirm that your device has been connected successfully. But if it doesn’t turn blue then it’s more likely to be problem with the device drivers. So check whether you’ve properly installed device specific drivers on your PC or not.

Step 6: Now, tick against ‘AP’ button and navigate to the tar.md5 file from the firmware package & select it (The firmware file will look something like: I9300IDDUANE1_I9300IODDANE1_IN.tar.md5). Wait till Odin verifies the md5 hash. If it’s successful then there won’t be any warning message. Step 7: Tick the Auto Reboot option and F.Reset option located on the Odin window. Do not tick or un-tick any other option especially ticking Re-partition option may brick your phone. Don’t ignore these crucial precautions before going ahead. Step 8: After attempting everything as mentioned, initiate the process by clicking on the Start button present on the Odin window. You’ll notice that your phone automatically reboots itself while going through the process. Make sure that you won’t remove the USB cable until the process completes, as this may interrupt it.
