If you’ve ever downloaded official firmware for an Oppo, Realme, or OnePlus device, you’ve likely encountered the dreaded file. While convenient for stock recovery updates, OZIP is a closed, encrypted archive that standard tools (like 7-Zip or WinRAR) cannot open.

Converting an OZIP file to a Scatter File is not trivial. It is a delicate process of decryption, decompression, partition boundary reconstruction, and address mapping.

Move your downloaded .ozip firmware file into the same folder as the Python script.

To get a scatter file from an OZIP firmware, you must first decrypt the OZIP into a standard ZIP, extract the raw image files, and then generate or locate the scatter file. Step 1: Decrypt OZIP to standard ZIP

This is widely regarded as the most stable and high-quality solution for reversing the encryption. It works by identifying the "OPPOENCRYPT!" header, decrypting the data, and converting it into a flashable format bkerler.github.io .

The proposed OZIP to scatter file converter will be a software tool with a user-friendly interface. It will support the following features:

to generate the final Scatter file and raw images for flashing. Step 1: Decrypting the OZIP File

Ensure Python 3.x or higher is installed on your system and added to your system's environmental variables (PATH).
