В чем разница между прошивкой шлема по воздуху (OTA), вручную, и через веб-сайт Meta?

Здесь мы попробуем окончательно прояснить вопрос, по поводу которого сломана не одна тысяча копий: как же все-таки лучше и безопасней прошивать шлем, по воздуху, через официальный источник, или вручную, заливкой файла непосредственно на шлем командой adb sideload update.zip?

Разбор пойдет только в контексте шлемов Meta Quest, поскольку со смартфонами чуть более другая сиуация.

Итак, в чем же разница?

Краткий ответ: ни в чем. Этим можно было бы и ограничиться, но, боюсь, такой ответ никого не убедит. Поэтому далее будут пояснения.

 

Давайте начнем с того, что, собственно, представляет собой прошивка? А точнее, процесс прошивки.

Он происходит в несколько этапов:

  1. Отправка файла прошивки на шлем
  2. Проверка файла прошивки на целостность и на соответствие сертификатов и хэшей.
  3. Передача файла прошивки процессу update_engine
  4. "Потрошение" файла прошивки на блоки/разделы
  5. Проверка хэшей каждого "распотрошенного" блока
  6. Создание снепшотов (копий состояния) системных разделов
  7. Обновление системных разделов в неактивном слоте
  8. Проверка обновленных разделов на корректность и целостность
  9. Слияние снепшотов с системными разделами
  10. Выполнение нескольких проверок загрузки с обновленного слота
  11. При успешных проверках переключение на обновленный слот
  12. Штатная загрузка системы с обновленного слота
  13. Обновление другого слота.

Следует отметить, что это очень упрощенное описание того, что происходит при обновлении. Подробней можно прочитать здесь: https://source.android.com/docs/core/ota/ab?hl=en

Я намеренно не стал разделять способы ручной и "воздушной" прошивок, так как по сути, они отличаются всего лишь методом доставки файла прошивки на шлем. Это пункт 1.

При OTA прошивке файл прилетает по воздуху (Over-The-Air), а при ручной - доставляется по кабелю командой adb sideload update.zip.

 

Подчеркну: команда (и он же режим) sideload - это доставка файла на шлем, а не его прошивка. Проще говоря, это фактически команда copy или adb push в контексте Андроид, но специализированная. А вот после передачи файла прошивки на шлем, им занимается уже непосредственно процесс update_engine. В обоих случаях, как при OTA, так и вручную.

 

И потому не имеет значения, каким образом файл доставлен на шлем, его целостность и корректность в любом случае будет проверена дважды перед началом прошивки, а также несколько раз непосредственно в момент прошивки и конечно же после прошивки, с помощью drm-verify.

 

Еще и поэтому не шлем невозможно залить кастомные прошивки, т.к. уже на этапе проверки файла он будет отброшен из-за несовпадения хэшей.

 

Картинка, иллюстрирующая процесс начала прошивки:

Есть еще один несложный способ убедиться в отсутствии отличий - достаточно скачать со шлема bugreport и заглянуть в лог-файлы update_engine, по ним отчетливо видно, что прошивка в обоих случаях проходит одинаково.

 

Кладу под спойлер логи от update_engine:

Сдается мне, многих интересует вопрос: почему везде утверждают, что при ручной прошивке шлем окирпичивается чаще?

Отвечу так: это заблуждение. Все подобные аргументы в стиле "мой знакомый поел огурцов и умер. Огурцы смертельны". 

 

Также существует еще один момент связанный с региональными особенностями, это объясняет, почему многие сервисники склонны думать, что ручное обновление приводит к кирпичу.

Дело в том, что русскоязычный сегмент пользователей шлемов чаще обновляет шлем вручную, просто потому, что серверы Меты заблокированы в РФ и это затрудняет обновление прошивки по воздуху. Если взглянуть на западный сегмент пользователей, то там ситуация с точностью до наоборот, достаточно зайти на Реддит или форум Мета - создается впечатление, что шлемы окирпичиваются только при прошивке по воздуху.

 

Нет никакких статистических данных о том, что ручная прошивка более опасна, чем воздушная. Я читал Реддит, форум Мета, 4пда и другие форумы - там полно сообщений об окирпичивании при обновлении по OTA, и их намного больше, чем при ручной прошивке.
