IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to verify that their devices meet the following requirements.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and ensure the USB Debugging Mode is turned on.]

3) As the tutorial might wipe out all data of the phone, create a backup. If the device is having any custom recoveries such as ClockworkMod/TWRP already installed then back up data using the recovery.

4) The battery of Galaxy S3 should have charge above 80%.

5) The device should be factory unlocked and not locked to a particular carrier.

6) The phone will lose custom ROM with the installation of official firmware. Also, it will lose custom recovery such as CWM/TWRP which will be replaced by stock recovery.

7) The device will no longer belong to a rooted version once official build is installed.

8) The Android 4.1.2 XXEMD3 Jelly Bean works only on Samsung Galaxy S3 GT-I9300. As flashing this on any other variant might brick the device, verify the model number of the Galaxy device by navigating to Settings>> About Phone>> Model number.

Steps to install Android 4.1.2 XXEMD3 Jelly Bean on Samsung Galaxy S3 GT-I9300

Step-1: Download Android 4.1.2 XXEMD3 Jelly Bean official update for Samsung Galaxy S3 to the computer

Step-2: Extract the downloaded firmware zip file to get a .tar.md5 file with some other files

Step-3: Download Odin v3.07 which will help to install the Jelly Bean firmware. Extract Odin zip to get Odin3 v3.07.exe along with few other files

Then press the Volume Up button again to continue to enter Download Mode

Step-5: Run Odin3 v3.07.exe as an Administrator

Step-6: Connect the Galaxy S3 to the computer using USB cable while it is in the Download Mode. Wait until Odin detects the device. When the phone is connected successfully, the ID: COM box in Odin will turn yellow with COM port number. Also, the successful connection will be indicated by an Added message in Odin.

Note: If the Added message does not appear, then try the USB port at the back of the computer. In case that too does not work, then re-install USB driver.

Step-9: Hit the Start button in Odin. The installation should begin now and would take few minutes to complete

Step-10: When the installation process is completed, the phone will then restart automatically. Soon, a PASS message with green background will appear in the extreme left box at the very top of Odin indicating successful installation. After the home screen appears on the phone, unplug the USB cable from the device to disconnect it from the computer
