JFWChanger is another Jiggy application that will let you change your firmware to just about anything you like. When you start the app, you have 2 buttons, a custom firmware and a preset. The custom firmware let’s you set any firmware version you like, even with build version. The preset let’s you chose any already existing firmware, ranging from 1.1 to 2.0.
