But your linker needs a Scatter File (common in ARM’s armlink or Keil µVision). How do you bridge that gap?
Since .ozip files are encrypted, you need a decryption tool to turn them into a standard .zip file. Ozip File To Scatter File Converter
As manufacturers move away from proprietary Ozip to standard payload.bin (Android OTA) or super.img (dynamic partitions), the need for Ozip-specific converters may shrink. However, as of 2025, BBK phones still ship Ozip for stock recovery updates. Understanding OZIP and Scatter Files
[Revised] How to use SP Flash tool to flash Mediatek firmware But your linker needs a Scatter File (common
SP Flash Tool → Write Memory → Region: EMMC_USER → Address: (from a known working scatter).ozip2payload) convert Ozip into Google’s payload.bin, then payload_dumper extracts images, and finally payload2scatter creates the scatter. This is more complex but works for v3 encryption.Warning Regarding Ozip Conversion: 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. Always verify the device model number (e.g., CPH1859, RMX1851) matches the firmware before proceeding.
An Ozip to Scatter File Converter bridges the gap between proprietary packed firmware and open flash tools. While not trivial (due to obfuscation), it is achievable for many common Ozip implementations. The result is greater control over embedded device flashing, recovery, and customization.
