Не удалось применить инкрементный OTA AOSP ⇐ Android

[Anonymous]

Мне удалось успешно создать добавочный пакет OTA, но попытка применить его не удалась.
Ниже приведены шаги по созданию добавочного пакета OTA.

Код: Выделить всё

1. $ Source...
2. $ lunch...
3. $ make -j32
//Flash the images in the device which are generated inside of "{root}/out/target/product//*.img" directory.
4. $ make target-files-package -j4
// this will generate the previously changed target file in "{root}/out/target/product//obj/PACKAGING/target_files_intermediates/" directory
Copy the PREVIOUS-target_files.zip to ${root}
- Apply the changes in the source
5. $ make target-files-package -j4
// this will generate the previously changed target file in "{root}/out/target/product//obj/PACKAGING/target_files_intermediates/" directory
Copy the NEW-target_files.zip to ${root}
6. ./build/tools/releasetools/ota_from_target_files -i PREVIOUS-target_files.zip NEW-target_files.zip incremental_ota_update.zip

Теперь применяю инкрементальный_ota_update.zip из моего СИСТЕМНОГО приложения с помощью UpdateEngine, и в журнале появляется ошибка ниже:
