Doug Zongkerd4208f92010-09-20 12:16:13 -0700142 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800143 * --wipe_data - erase user data (and cache), then reboot
Paul Crowley08404b42016-12-19 13:04:23 -0800144 * --prompt_and_wipe_data - prompt the user that data is corrupt,

156 * 2. main system writes "--wipe_data" to /cache/recovery/command
157 * 3. main system reboots into recovery
158 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
159 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700160 * 5. erase_volume() reformats /data

163 * -- after this, rebooting will restart the main system --
164 * 8. main() calls reboot() to boot main system
165 *
166 * OTA INSTALL
167 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700168 * 2. main system writes "--update_package=/cache/some-filename.zip"

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