92 * The recovery tool communicates with the main system through /cache files.
93 * /cache/recovery/command - INPUT - command line for tool, one arg per line
94 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
95 * /cache/recovery/intent - OUTPUT - intent that was passed in
96 *
97 * The arguments which may be supplied in the recovery.command file:
98 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -070099 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800100 * --wipe_data - erase user data (and cache), then reboot
101 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800102 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

105 * After completing, we remove /cache/recovery/command and reboot.
106 * Arguments may also be supplied in the bootloader control block (BCB).
107 * These important scenarios must be safely restartable at any point:
108 *
109 * FACTORY RESET
110 * 1. user selects "factory reset"
111 * 2. main system writes "--wipe_data" to /cache/recovery/command
112 * 3. main system reboots into recovery
113 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
114 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700115 * 5. erase_volume() reformats /data
116 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800117 * 7. finish_recovery() erases BCB
118 * -- after this, rebooting will restart the main system --
119 * 8. main() calls reboot() to boot main system
120 *
121 * OTA INSTALL
122 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700123 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800124 * 3. main system reboots into recovery
125 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
126 * -- after this, rebooting will attempt to reinstall the update --
127 * 5. install_package() attempts to install the update
128 * NOTE: the package install must itself be restartable from any point
129 * 6. finish_recovery() erases BCB
130 * -- after this, rebooting will (try to) restart the main system --
131 * 7. ** if install failed **
132 * 7a. prompt_and_wait() shows an error icon and waits for the user
133 * 7b; the user reboots (pulling the battery, etc) into the main system
134 * 8. main() calls maybe_install_firmware_update()
135 * ** if the update contained radio/hboot firmware **:
136 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
137 * -- after this, rebooting will reformat cache & restart main system --
138 * 8b. m_i_f_u() writes firmware image into raw cache partition
139 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
140 * -- after this, rebooting will attempt to reinstall firmware --
141 * 8d. bootloader tries to flash firmware
142 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
143 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700144 * 8f. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800145 * 8g. finish_recovery() erases BCB
146 * -- after this, rebooting will (try to) restart the main system --
