| * 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) |
| * /cache/recovery/intent - OUTPUT - intent that was passed in |
| * |
| * The arguments which may be supplied in the recovery.command file: |
| * --send_intent=anystring - write the text out to recovery.intent |
| * --update_package=root:path - verify install an OTA package file |
| * --wipe_data - 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 |
| * |
| * 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_root() reformats /data |
| * 6. erase_root() 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 |
| * 8. main() calls maybe_install_firmware_update() |
| * ** if the update contained radio/hboot firmware **: |
| * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache" |
| * -- after this, rebooting will reformat cache & restart main system -- |
| * 8b. m_i_f_u() writes firmware image into raw cache partition |
| * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache" |
| * -- after this, rebooting will attempt to reinstall firmware -- |
| * 8d. bootloader tries to flash firmware |
| * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache") |
| * -- after this, rebooting will reformat cache & restart main system -- |
| * 8f. erase_root() reformats /cache |
| * 8g. finish_recovery() erases BCB |
| * -- after this, rebooting will (try to) restart the main system -- |
| * 9. main() calls reboot() to boot main system |
| * |
| * SECURE FILE SYSTEMS ENABLE/DISABLE |
| * 1. user selects "enable encrypted file systems" |
| * 2. main system writes "--set_encrypted_filesystems=on|off" to |
| * /cache/recovery/command |
| * 3. main system reboots into recovery |
| * 4. get_args() writes BCB with "boot-recovery" and |
| * "--set_encrypted_filesystems=on|off" |
| * -- after this, rebooting will restart the transition -- |
| * 5. read_encrypted_fs_info() retrieves encrypted file systems settings from /data |
| * Settings include: property to specify the Encrypted FS istatus and |
| * FS encryption key if enabled (not yet implemented) |
| * 6. erase_root() reformats /data |
| * 7. erase_root() reformats /cache |
| * 8. restore_encrypted_fs_info() writes required encrypted file systems settings to /data |
| * Settings include: property to specify the Encrypted FS status and |
| * FS encryption key if enabled (not yet implemented) |
| * 9. finish_recovery() erases BCB |
