98 * The recovery tool communicates with the main system through /cache files.
99 * /cache/recovery/command - INPUT - command line for tool, one arg per line
100 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
101 * /cache/recovery/intent - OUTPUT - intent that was passed in
102 *
103 * The arguments which may be supplied in the recovery.command file:
104 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -0700105 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800106 * --wipe_data - erase user data (and cache), then reboot

Oscar Montemayor05231562009-11-30 08:40:57 -0800108 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

113 * These important scenarios must be safely restartable at any point:
114 *
115 * FACTORY RESET
116 * 1. user selects "factory reset"
117 * 2. main system writes "--wipe_data" to /cache/recovery/command
118 * 3. main system reboots into recovery
119 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
120 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700121 * 5. erase_volume() reformats /data
122 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800123 * 7. finish_recovery() erases BCB
124 * -- after this, rebooting will restart the main system --
125 * 8. main() calls reboot() to boot main system
126 *
127 * OTA INSTALL
128 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700129 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800130 * 3. main system reboots into recovery
131 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
132 * -- after this, rebooting will attempt to reinstall the update --
133 * 5. install_package() attempts to install the update
134 * NOTE: the package install must itself be restartable from any point
135 * 6. finish_recovery() erases BCB
136 * -- after this, rebooting will (try to) restart the main system --
137 * 7. ** if install failed **
138 * 7a. prompt_and_wait() shows an error icon and waits for the user
139 * 7b; the user reboots (pulling the battery, etc) into the main system
140 * 8. main() calls maybe_install_firmware_update()
141 * ** if the update contained radio/hboot firmware **:
142 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
143 * -- after this, rebooting will reformat cache & restart main system --
144 * 8b. m_i_f_u() writes firmware image into raw cache partition
145 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
146 * -- after this, rebooting will attempt to reinstall firmware --
147 * 8d. bootloader tries to flash firmware
148 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
149 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700150 * 8f. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800151 * 8g. finish_recovery() erases BCB
