The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800139 *
140 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -0700141 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800142 * --wipe_data - erase user data (and cache), then reboot
Paul Crowley08404b42016-12-19 13:04:23 -0800143 * --prompt_and_wipe_data - prompt the user that data is corrupt,
144 * with their consent erase user data (and cache), then reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800145 * --wipe_cache - wipe cache (but not user data), then reboot

153 * FACTORY RESET
154 * 1. user selects "factory reset"
155 * 2. main system writes "--wipe_data" to /cache/recovery/command
156 * 3. main system reboots into recovery
157 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
158 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700159 * 5. erase_volume() reformats /data
160 * 6. erase_volume() reformats /cache

162 * -- after this, rebooting will restart the main system --
163 * 8. main() calls reboot() to boot main system
164 *
165 * OTA INSTALL
166 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700167 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800168 * 3. main system reboots into recovery

170 * -- after this, rebooting will attempt to reinstall the update --
171 * 5. install_package() attempts to install the update
172 * NOTE: the package install must itself be restartable from any point
173 * 6. finish_recovery() erases BCB
174 * -- after this, rebooting will (try to) restart the main system --
175 * 7. ** if install failed **
176 * 7a. prompt_and_wait() shows an error icon and waits for the user
