Android 10 OTA update: Internals introduction
summary
Research reconstructs AOSP OTA internals for a Qualcomm Aurora BSP and produces a working full A/B seamless full OTA flow rather than incremental or legacy updates. The build traces make/soong/ninja targets to produce target_files.zip and then runs the python packer and payload_generator delta compression to emit update.zip whose largest artifact is payload.bin 1.8 GB. Development uses Ubuntu with Double Commander and VS Code, inspects update_engine protobufs, and validates that the engine streams to the non‑active slot and runs as a regular process.
