135 * The recovery tool communicates with the main system through /cache files.
136 * /cache/recovery/command - INPUT - command line for tool, one arg per line

The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800138 *
139 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -0700140 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800141 * --wipe_data - erase user data (and cache), then reboot
Paul Crowley08404b42016-12-19 13:04:23 -0800142 * --prompt_and_wipe_data - prompt the user that data is corrupt,
143 * with their consent erase user data (and cache), then reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800144 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800145 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

148 * After completing, we remove /cache/recovery/command and reboot.
149 * Arguments may also be supplied in the bootloader control block (BCB).
150 * These important scenarios must be safely restartable at any point:
151 *
152 * FACTORY RESET
153 * 1. user selects "factory reset"
154 * 2. main system writes "--wipe_data" to /cache/recovery/command
155 * 3. main system reboots into recovery
156 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
157 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700158 * 5. erase_volume() reformats /data
159 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800160 * 7. finish_recovery() erases BCB
161 * -- after this, rebooting will restart the main system --
162 * 8. main() calls reboot() to boot main system
163 *
164 * OTA INSTALL
165 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700166 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800167 * 3. main system reboots into recovery
168 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
169 * -- after this, rebooting will attempt to reinstall the update --
170 * 5. install_package() attempts to install the update
171 * NOTE: the package install must itself be restartable from any point
172 * 6. finish_recovery() erases BCB
173 * -- after this, rebooting will (try to) restart the main system --
174 * 7. ** if install failed **
175 * 7a. prompt_and_wait() shows an error icon and waits for the user
