What is cache data android recovery

Ликбез по Recovery и вайпам для новичков

(1) Recovery (кастомный)

В двух словах, CWM, TWRP – это альтернативные рекавери (recovery) для Android устройств. Обычно их устанавливают по инструкции после разблокировки бутлоадера. С их помощью устанавливают/обновляют прошивки, патчи, гапсы и прочее.

Немного банального (азы):

— Install — установка прошивки и прочих файлов *.zip (update.zip, gapps.zip, lineageos.zip и т.д.)

— Wipe — очистка данных (подробнее об этом поговорим ниже)

— Backup — бэкап системы (с возможностью выбора нужных разделов), в дальнейшем при необходимости (проблемах) можно будет воспользоваться этим (созданным заранее) бэкапом.

— Restore — собственно команда отвечающая за восстановление системы из бэкапа (если таковой был сделан).

— Mount USB Storage — монтирование флешки, подключенной через OTG. Обычно это нужно для подключения устройства к ПК прямо из рекавери (twrp), например чтобы скинуть другую прошивку, гаппсы и прочие файлы.

— File Manager – менеджер файлов.

— Reboot — перезагрузка устройства

(2) WIPE

— Wipe Factory Reset — это совокупность нескольких вайпов (wipe data, cache и dalvik cache) по простому сброс до заводских настроек. Сотрутся все программы, обновление системных приложений, аккаунты, смс, вызовы, телефонная книга, настройки программ и системы. Получаем аппарат как с магазина, кроме оставшихся: фото, видео, документов, скаченных файлов, картинок и прочего, Вами скопированного на встроенный, внешний накопители, контента.

— Вы можете выбрать Advanced wipe и выбрать те вайпы которые необходимо сделать. Коротко про каждый вайп:

— Cache — очистка раздела /cache , удаляться временные данные деятельности программ.

— Dalvik Cache — очистка Dalvik Cache, оптимизированные dex файлы для каждого приложения. Если очистить, файлы создадутся заново, обычно это необходимо при обновлении прошивки или гаппсов.

— Wipe Data — очистка раздела /data , удаляться все ваши программы их данные, личные настройки..

— Wipe System — очистка раздела /system устройства, по простому удаление прошивки.

— External Storage — очистка внешней памяти SD карты устройства.

— Internal Storage — очистка внутренней памяти устройства.

Не отмечайте пункт System, если вы не планируете затем устанавливать полную прошивку или не уверены в своих силах. Если вайпнуть систему и не прошить новую прошивку, устройство не запустится.

(3) Форматирование пользовательского раздела (/data)

Причины по которым вам могут посоветовать сделать формат:

— Продажа аппарата. Это действие гарантирует полное удаление данных с телефона связанных с предыдущим владельцем на устройствах, у которых накопитель объединен с разделом /data.

— После/до установки авторских, модифицированных прошивок.

— Зависание при включении, спонтанная перезагрузка, постоянная перезагрузка, даже после заводского сброса.

— Сбои в работе приложений, даже после заводского сброса.

Все симптомы вызваны зачастую ошибками файловой системы. А заводской сброс не всегда означает именно форматирование раздела, т.е создание новой файловой системы, а не просто удаление с раздела папок/файлов.

1. Загрузить меню recovery
2. Выбрать пункт меню: Wipe.
3. Нажать кнопку: Format Data.
4. Набрать на клавиатуре слово: yes, и нажать кнопку: Go.
5. По завершении процесса можно вернутся в основное меню, нажав кнопку: Дом.
6. Для перезагрузки устройства в обычный режим выбрать: Reboot — Reboot System.

(4) Процедура выборочного стирания

Разберем на примере. Предположим необходимо привести смартфон на текущей прошивке, без каких-либо обновлений, модификаций и перепрошивок в идеальнейше-чистое (нулевое) состояние, и удалить не только пользовательские данные но и весь контент с устройства и вставленной SD-карты. Произойдет потеря абсолютно всех данных. Позаботьтесь о резервной копии своих документов, фото, видео, музыки и прочего.

1. Загрузить меню recovery.
2. Выбрать пункт меню: Wipe.
3. Нажать кнопку: Advanced Wipe.
4. Отметить пункты: Cache, Data, Internal Storage, external microSD.
5. Свайп вправо запустит процесс стирания данных или форматирования разделов и накопителей.
6. Для перезагрузки устройства в обычный режим выбрать: Reboot — Reboot System.
