90 * The recovery tool communicates with the main system through /cache files.
91 * /cache/recovery/command - INPUT - command line for tool, one arg per line
92 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080093 *
94 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -070095 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080096 * --wipe_data - erase user data (and cache), then reboot
Tao Baof9f17342018-04-27 10:44:04 -070097 * --prompt_and_wipe_data - prompt the user that data is corrupt, with their consent erase user
98 * data (and cache), then reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080099 * --wipe_cache - wipe cache (but not user data), then reboot
Tao Baof9f17342018-04-27 10:44:04 -0700100 * --show_text - show the recovery text menu, used by some bootloader (e.g. http://b/36872519).
Oscar Montemayor05231562009-11-30 08:40:57 -0800101 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Doug Zongkere5d5ac72012-04-12 11:01:22 -0700102 * --just_exit - do nothing; exit and reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800103 *
104 * After completing, we remove /cache/recovery/command and reboot.
105 * Arguments may also be supplied in the bootloader control block (BCB).
106 * These important scenarios must be safely restartable at any point:
107 *
108 * FACTORY RESET
109 * 1. user selects "factory reset"
110 * 2. main system writes "--wipe_data" to /cache/recovery/command
111 * 3. main system reboots into recovery
112 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
113 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700114 * 5. erase_volume() reformats /data
115 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800116 * 7. finish_recovery() erases BCB
117 * -- after this, rebooting will restart the main system --
118 * 8. main() calls reboot() to boot main system
119 *
120 * OTA INSTALL
121 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700122 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800123 * 3. main system reboots into recovery
124 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
125 * -- after this, rebooting will attempt to reinstall the update --
126 * 5. install_package() attempts to install the update
127 * NOTE: the package install must itself be restartable from any point
128 * 6. finish_recovery() erases BCB
129 * -- after this, rebooting will (try to) restart the main system --
130 * 7. ** if install failed **
131 * 7a. prompt_and_wait() shows an error icon and waits for the user
Tao Baoc0336392016-12-13 22:29:49 -0800132 * 7b. the user reboots (pulling the battery, etc) into the main system
