* 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=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_volume() reformats /userdata
|
* 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
|
* 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_volume() 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 /userdata
|
* Settings include: property to specify the Encrypted FS istatus and
|
* FS encryption key if enabled (not yet implemented)
|
* 6. erase_volume() reformats /userdata
|
* 7. erase_volume() reformats /cache
|
* 8. restore_encrypted_fs_info() writes required encrypted file systems settings to /userdata
|
* Settings include: property to specify the Encrypted FS status and
|
* FS encryption key if enabled (not yet implemented)
|
* 9. finish_recovery() erases BCB
