    Extracting vendor files for Pixel devices

    + +

    This section is specific to Pixel devices. The emulator and generic targets don't + require extra vendor files.

    + +

    Many of these components are already open source, but not everything is set up to + be built by the Android Open Source Project build system. Switching to building these + components from source will be an incremental effort. In many cases, the vendor files + simply need to be ignored and AOSP will already provide them instead. Firmware cannot + generally be built from source even when sources are available, other than to verify + that the official builds match the sources, since it has signature verification (which + is an important part of the verified boot and attestation security model).

    + +
    +

    Pixel 5 and earlier

    + +

    Extract the vendor files corresponding to the matching release with + DEVICE and BUILD_ID replaced with the + appropriate values:

    + + 
    vendor/android-prepare-vendor/execute-all.sh -d DEVICE -b BUILD_ID -o vendor/android-prepare-vendor
+mkdir -p vendor/google_devices
+rm -rf vendor/google_devices/DEVICE
+mv vendor/android-prepare-vendor/DEVICE/BUILD_ID/vendor/google_devices/* vendor/google_devices/
    +
    + +
    +

    Pixel 6 and later

    + +

    Starting with the Pixel 6, newer generation devices use the adevtool project to + extract files from the stock operating system. +

    + + 
    cd vendor/adevtool/ && yarn install && cd ../..
+vendor/adevtool/mountimages.bash DEVICE BUILD_ID
+sudo vendor/adevtool/bin/run generate-all vendor/adevtool/config/DEVICE.yml -c vendor/state/DEVICE.json -f vendor/adevtool/dl/DEVICE-BUILD_ID-*.zip -s vendor/adevtool/dl/DEVICE-BUILD_ID/mount/
    + +

    OTA firmware extraction is currently a work-in-progress on adevtool. + android-prepare-vendor is being temporarily used to make the process easier.
