1. Rename theme to “update.zip”
Themes usually come in .zip format showing its title. Download a theme you like and rename the file to “update.zip” (right click file > click “Rename”)
Tip: If you want to store several themes, keep them with original file names in a folder named “Android Themes.” When you desire to load a theme, you can copy it to the SD card first and then rename the copied file to “update.zip”
