How to Install Official Android 4.1.2 XXAMD3 Jelly Bean OTA on Galaxy S3 Mini I8190
- Download Android 4.1.2 XXAMD3 official firmware for Galaxy S3 Mini and save it on computer. Extract the contents of the firmware zip file to a folder on desktop and you will get a .tar or .tar.md5 file.
- Download Odin v3.07 and extract its contents to a new folder on computer.
- Power off the smartphone and boot into Download Mode by pressing and holding Volume Down, Home and Power buttons together. Wait until the "Warning!" message appears, and then release all three buttons. Then hit Volume Up button to confirm entry into Download Mode.
- Launch ODIN on computer as Administrator, as admin privileges are required to complete the installation smoothly.
- Now connect the phone to computer via USB cable. Wait until the message "Added!" appears in Odin message box. If the message fails to appear, then it could be an issue with phone's connection, or USB port or require re-installation of Samsung USB drivers. Once the device connects successfully, an "Added!" message appears on screen and you can proceed to the next step.
- Load the following files in ODIN from the extracted XXAMD3 folder, using respective checkbox options:
- Select the PDA checkbox, and click the file named '.tar.md5' (required)
- Choose the Phone checkbox, and select the file named 'modem' (ignore if the file is not found in the extracted folder)
- Click the CSC checkbox, and choose the file named 'CSC' (ignore if the file is missing)
- Choose the PIT checkbox, and click the '.pit' file. (ignore if there is no such file)
- Leave all the options in ODIN at their default settings. But, ensure that Re-partition option is unchecked and proceed to the next step.
- Hit Start in ODIN to begin the flashing process
- The firmware installation may take about 10 to 15 minutes to complete and then the phone will automatically reboot. Now the device will reboot for the first time, which could take about 5 minutes to complete. So, please be patient.
- Finally, when the Samsung logo appears, unplug the USB cable to disconnect the phone from computer. Once the device has booted up into the newly installed firmware, enter your Google Account login details and start working with its new features and functions.
- If a FAIL message appears in Odin or it freezes/stops responding: disconnect the phone from computer, remove the phone's battery and then re-insert it after five seconds. Repeat the tutorial from scratch and ensure that all steps are performed in order.
- If a PASS message pops-up in Odin, but the device gets stuck at Samsung logo or enters boot loop, then perform a Wipe Data/Factory Reset from Recovery mode. Here are the steps:
- Power off the phone completely and boot it into Recovery mode as follows: press and hold Volume Up, Home and Power buttons together. Release all three buttons after the screen flickers and wait for a few seconds.
- Select wipe data/ factory reset option and click Yes to confirm.
- Return to the main recovery menu and choose reboot system now option.
- Wait for a few minutes until the first boot completes.
- Enter your Google login details when the home screen appears.
