75 * The recovery tool communicates with the main system through /cache files.
76 * /cache/recovery/command - INPUT - command line for tool, one arg per line
77 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080078 *
79 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -070080 * --update_package=path - verify install an OTA package file
Tianjie Xue5218612019-06-25 13:59:39 -070081 * --install_with_fuse - install the update package with FUSE. This allows installation of large
82 * packages on LP32 builds. Since the mmap will otherwise fail due to out of memory.
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080083 * --wipe_data - erase user data (and cache), then reboot
Tao Baof9f17342018-04-27 10:44:04 -070084 * --prompt_and_wipe_data - prompt the user that data is corrupt, with their consent erase user
85 * data (and cache), then reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080086 * --wipe_cache - wipe cache (but not user data), then reboot
Tao Baof9f17342018-04-27 10:44:04 -070087 * --show_text - show the recovery text menu, used by some bootloader (e.g. http://b/36872519).
Oscar Montemayor05231562009-11-30 08:40:57 -080088 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Doug Zongkere5d5ac72012-04-12 11:01:22 -070089 * --just_exit - do nothing; exit and reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080090 *
91 * After completing, we remove /cache/recovery/command and reboot.
92 * Arguments may also be supplied in the bootloader control block (BCB).
93 * These important scenarios must be safely restartable at any point:
94 *
95 * FACTORY RESET
96 * 1. user selects "factory reset"
97 * 2. main system writes "--wipe_data" to /cache/recovery/command
98 * 3. main system reboots into recovery
99 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
100 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700101 * 5. erase_volume() reformats /data
102 * 6. erase_volume() reformats /cache
Tianjie Xu164c60a2019-05-15 13:59:39 -0700103 * 7. FinishRecovery() erases BCB
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800104 * -- after this, rebooting will restart the main system --
105 * 8. main() calls reboot() to boot main system
106 *
107 * OTA INSTALL
108 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700109 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800110 * 3. main system reboots into recovery
111 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
112 * -- after this, rebooting will attempt to reinstall the update --
Tao Baoadc99ef2019-04-29 23:48:02 -0700113 * 5. InstallPackage() attempts to install the update
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800114 * NOTE: the package install must itself be restartable from any point
Tianjie Xu164c60a2019-05-15 13:59:39 -0700115 * 6. FinishRecovery() erases BCB
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800116 * -- after this, rebooting will (try to) restart the main system --
117 * 7. ** if install failed **
Tao Baoadc99ef2019-04-29 23:48:02 -0700118 * 7a. PromptAndWait() shows an error icon and waits for the user
Tao Baoc0336392016-12-13 22:29:49 -0800119 * 7b. the user reboots (pulling the battery, etc) into the main system
