* The recovery tool communicates with the main system through /cache files.

* /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
|
|
*
|
|
* The arguments which may be supplied in the recovery.command file:
|
|
* --update_package=path - verify install an OTA package file
|
|
* --wipe_data - erase user data (and cache), then reboot
|
|
* --prompt_and_wipe_data - prompt the user that data is corrupt, with their consent erase user
|
|
* data (and cache), then reboot
|
|
* --wipe_cache - wipe cache (but not user data), then reboot
|
|
* --show_text - show the recovery text menu, used by some bootloader (e.g. http://b/36872519).
|
|
* --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
|
|
* --just_exit - do nothing; exit and reboot
|
|
*
|
|
* After completing, we remove /cache/recovery/command and reboot.
|
|
* Arguments may also be supplied in the bootloader control block (BCB).
|
|
* These important scenarios must be safely restartable at any point:
|
|
*
|
|
* FACTORY RESET
|
|
* 1. user selects "factory reset"
|
|
* 2. main system writes "--wipe_data" to /cache/recovery/command
|
|
* 3. main system reboots into recovery
|
|
* 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
|
|
* -- after this, rebooting will restart the erase --
|
|
* 5. erase_volume() reformats /data
|
|
* 6. erase_volume() reformats /cache
|
|
* 7. finish_recovery() erases BCB
|
|
* -- after this, rebooting will restart the main system --
|
|
* 8. main() calls reboot() to boot main system
|
|
*
|
|
* OTA INSTALL
|
|
* 1. main system downloads OTA package to /cache/some-filename.zip
|
|
* 2. main system writes "--update_package=/cache/some-filename.zip"
|
|
* 3. main system reboots into recovery
|
|
* 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
|
|
* -- after this, rebooting will attempt to reinstall the update --
|
|
* 5. install_package() attempts to install the update
|
|
* NOTE: the package install must itself be restartable from any point
|
|
* 6. finish_recovery() erases BCB
|
|
* -- after this, rebooting will (try to) restart the main system --
|
|
* 7. ** if install failed **
|
|
* 7a. prompt_and_wait() shows an error icon and waits for the user
|
