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,

Doug Zongkerd4208f92010-09-20 12:16:13 -0700160 * 5. erase_volume() reformats /data

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 **
