You will also have use an at least Intel Pentium 1.8 GHz processor, to have minimum 1 GB of RAM, at least 500 MB of free hard drive space and a screen resolution of 1024 X 768 (32bit or above). It is also necessary to install Net Framework 3.5 SP1, Windows Media Player 10 or later, ActiveSync(Windows XP), Device Central(Windows Vista) and DirectX 9.0C. Download and install Kies. Close all the running applications from your cellphone and put it into idle mode. Open Kies, let the application detect the phone, go to Firmware Upgrade Initialisation menu and follow the onscreen instructions for a successful firmware upgrade.
