Upgrade Samsung Galaxy s-advance to official jellybean v 4.1.2

Upgrading Samsung galaxy s advance from phone is easy. If your device is currently running on official gingerbread rom, and you havent rooted it then follow these simple steps below:
But i recommend backing up your phone. Backing up contacts, messages, apps, and other necessary files is a must if you donot want to loose it all. Then head to the steps below:

• Go to the settings of your phone,
• scroll at the end where you will see About Phone
• Head inside and there you will find Software Update

Your phone must be connected to a working network. It will check for the available update and will start downloading the necessary update files. Donot switch off or take out the battery. After downloading, the phone will automatically restart and will start applying update. After successful operation, your phone will reboot again and have jellybean update installed. You can now enjoy jelly bean on your phone. I recommend you do a factory reset heading toward Settings->Backup and Reset and reset your phone.
Thats it.

If in-case the above step is not working and you somehow fail upgrading your phone to official jelly bean firmware, then you can try again using the next process. The following process to upgrade your galaxy s advance will require a working connection, some software that im gonna mention you and provide you the download link, a PC and the USB cable of the phone.
