This comprehensive guide explains what these files are, why you need to convert them, and provides a step-by-step walkthrough to get the job done safely. Understanding Ozip and Scatter Files
Converting Ozip files to Scatter files involves decrypting proprietary firmware. The generated Scatter file allows read/write access to partition images (system, boot, recovery, etc.). Use extreme caution when flashing files via SP Flash Tool using a converted scatter file. Flashing incorrect partitions or files intended for a different model variant can permanently brick your device.
