* The recovery tool communicates with the main system through /cache files. |
|
* /cache/recovery/command - INPUT - command line for tool, one arg per line |
|
* /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 |
|
* --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 |
|
* 7b. the user reboots (pulling the battery, etc) into the main system |
