What is an OZIP file? An OZIP file is a proprietary compressed image format used primarily by Android OEMs (like Asus, ZTE, and older Motorola devices) for firmware updates and system images. It is often an encrypted or transformed version of a standard EXT4, sparse image, or ZIP archive. It is often an encrypted or transformed version
