How to Update Galaxy S3 I9305 to Official Android 4.1.2 Jelly Bean with XXBMA3 OTA Firmware
1. Extract the downloaded XXBMA3 firmware zip file to a desired location (preferably desktop). Now, the extracted folder will contain a .tar file and some other files.
2. Extract Odin zip file to get Odin3 v3.07.exe along with few other files.
3. Switch off your Galaxy S3 phone and wait for vibration (about 5 to 6 seconds) to confirm complete device shutdown.
4. Place the phone in Download mode by pressing and holding Volume Down, Home and Power buttons together until Samsung Galaxy logo appears on screen. Wait for a few seconds until the phone enters Download mode.
5. Launch Odin3 v3.07.exe (locate file in Step 2), as an Administrator since Admin privileges are required to complete the flashing process.
6. Connect the Galaxy S3 I9305 to the computer with original USB cable. A message reading "Added!!" will appear in Odin's message box at the bottom left of screen. If the message fails to appear, then try another USB port (preferably the one at the back of the computer). If all else fails, then just reinstall USB drivers for the phone on computer. When the successfully "Added!!" message pops-up in Odin, proceed to the next step. At this point, the COM port with a corresponding number turns Yellow if you successfully added the device.
7. Choose the files from I9305XXBMA3 folder [check Step 1] in Odin using respective command buttons:
- Click the PDA Button, and choose the .tar file named 'Code'
- Tap the Phone Button, and choose file named 'Modem' (ignore if there is no such file)
- Hit the CSC Button, and choose file named 'CSC' (ignore if such file is missing)
- Tap the PIT Button, and select the .pit file. Use this file only if it is found among extracted files in step 1, otherwise ignore it.
8. In Odin, make sure Auto Reboot and F. Reset Time options are selected. The Re-Partition option must be chosen, only if you are using a .pit file in previous step.
9. Verify everything in Step 7 & Step 8 is done correctly. After confirming, hit the START button to begin the flashing process.
10. Once the firmware flashing completes, the smartphone will reboot automatically and a PASS message with green background appears in the left-most box at the very top of Odin. Now, disconnect the USB cable from computer and boot up the device into the newly installed firmware.
Galaxy S3 I9305 is now running Android 4.1.2 XXBMA3 Jelly Bean official firmware. Go to Settings > About Phone to verify the firmware version installed.
Note: If the Galaxy S3 gets stuck at booting animation after Step 10 then boot into Recovery mode (press and hold the Volume Up, Home and Power buttons together).
