131 * The recovery tool communicates with the main system through /cache files.
132 * /cache/recovery/command - INPUT - command line for tool, one arg per line
133 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800134 *
135 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -0700136 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800137 * --wipe_data - erase user data (and cache), then reboot
138 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800139 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Doug Zongkere5d5ac72012-04-12 11:01:22 -0700140 * --just_exit - do nothing; exit and reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800141 *
142 * After completing, we remove /cache/recovery/command and reboot.

144 * These important scenarios must be safely restartable at any point:
145 *
146 * FACTORY RESET
147 * 1. user selects "factory reset"
148 * 2. main system writes "--wipe_data" to /cache/recovery/command
149 * 3. main system reboots into recovery
150 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
151 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700152 * 5. erase_volume() reformats /data
153 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800154 * 7. finish_recovery() erases BCB
155 * -- after this, rebooting will restart the main system --
156 * 8. main() calls reboot() to boot main system
157 *
158 * OTA INSTALL
159 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700160 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800161 * 3. main system reboots into recovery

163 * -- after this, rebooting will attempt to reinstall the update --
164 * 5. install_package() attempts to install the update
165 * NOTE: the package install must itself be restartable from any point
166 * 6. finish_recovery() erases BCB
167 * -- after this, rebooting will (try to) restart the main system --
168 * 7. ** if install failed **
169 * 7a. prompt_and_wait() shows an error icon and waits for the user
170 * 7b; the user reboots (pulling the battery, etc) into the main system
171 * 8. main() calls maybe_install_firmware_update()
172 * ** if the update contained radio/hboot firmware **:
173 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
174 * -- after this, rebooting will reformat cache & restart main system --
175 * 8b. m_i_f_u() writes firmware image into raw cache partition
176 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
177 * -- after this, rebooting will attempt to reinstall firmware --
178 * 8d. bootloader tries to flash firmware
179 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
180 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700181 * 8f. erase_volume() reformats /cache
