Here is a great pack of brand new icons prepared by XDA member mikep1993. He calls it “MIcons Project”. The icon theme includes more then three hundred icon and icon base & masks to cover all apps on your Android device on MIUI ROM. The icon theme is compatible with both, MIUI V4 and MIUI GB . Since the project is still under development, be prepared to see more icons in the future. Download the “MIcons Project.mtz” from below and copy it to the MIUI/Theme folder on your internal SD Card. Open Theme changer app and click on Mixed tab, then apply the icons.
