98 * /cache/recovery/command - INPUT - command line for tool, one arg per line
99 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
100 * /cache/recovery/intent - OUTPUT - intent that was passed in
101 *
102 * The arguments which may be supplied in the recovery.command file:
103 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -0700104 * --update_package=path - verify install an OTA package file

112 * These important scenarios must be safely restartable at any point:
113 *
114 * FACTORY RESET
115 * 1. user selects "factory reset"
116 * 2. main system writes "--wipe_data" to /cache/recovery/command
117 * 3. main system reboots into recovery
118 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
119 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700120 * 5. erase_volume() reformats /data
121 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800122 * 7. finish_recovery() erases BCB
123 * -- after this, rebooting will restart the main system --
124 * 8. main() calls reboot() to boot main system
125 *
126 * OTA INSTALL
127 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700128 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800129 * 3. main system reboots into recovery
130 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
131 * -- after this, rebooting will attempt to reinstall the update --
132 * 5. install_package() attempts to install the update
133 * NOTE: the package install must itself be restartable from any point
134 * 6. finish_recovery() erases BCB
135 * -- after this, rebooting will (try to) restart the main system --
136 * 7. ** if install failed **
137 * 7a. prompt_and_wait() shows an error icon and waits for the user
138 * 7b; the user reboots (pulling the battery, etc) into the main system
139 * 8. main() calls maybe_install_firmware_update()
140 * ** if the update contained radio/hboot firmware **:
141 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
142 * -- after this, rebooting will reformat cache & restart main system --
143 * 8b. m_i_f_u() writes firmware image into raw cache partition
144 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
145 * -- after this, rebooting will attempt to reinstall firmware --
146 * 8d. bootloader tries to flash firmware
147 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
148 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700149 * 8f. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800150 * 8g. finish_recovery() erases BCB
