Pre-Requisites
Do not proceed further with low battery power. Charge your Galaxy S2 I9100 at least up to 60% as a lack of battery power can increase the chances of interruption during the flashing process.Take a complete backup of all your important phone data and settings including your contacts, apps, messages, call logs, memos and APN settings, etc. before moving ahead. This is necessary as everything gets wiped out after flashing this firmware update. Install mobile-specific drivers on your PC to detect your Galaxy S2 I9100 when you connect it to your PC. You can install the drivers from the Samsung Kies CD which you’ve got at the time of purchase or just manually install them from the link given below.
