133 * The recovery tool communicates with the main system through /cache files.
134 * /cache/recovery/command - INPUT - command line for tool, one arg per line
135 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800136 *
137 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -0700138 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800139 * --wipe_data - erase user data (and cache), then reboot
140 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800141 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Doug Zongkere5d5ac72012-04-12 11:01:22 -0700142 * --just_exit - do nothing; exit and reboot
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800143 *
144 * After completing, we remove /cache/recovery/command and reboot.
145 * Arguments may also be supplied in the bootloader control block (BCB).
146 * These important scenarios must be safely restartable at any point:
147 *
148 * FACTORY RESET
149 * 1. user selects "factory reset"
150 * 2. main system writes "--wipe_data" to /cache/recovery/command
151 * 3. main system reboots into recovery
152 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
153 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700154 * 5. erase_volume() reformats /data
155 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800156 * 7. finish_recovery() erases BCB
157 * -- after this, rebooting will restart the main system --
158 * 8. main() calls reboot() to boot main system
159 *
160 * OTA INSTALL
161 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700162 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800163 * 3. main system reboots into recovery
164 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
165 * -- after this, rebooting will attempt to reinstall the update --
166 * 5. install_package() attempts to install the update
167 * NOTE: the package install must itself be restartable from any point
168 * 6. finish_recovery() erases BCB
169 * -- after this, rebooting will (try to) restart the main system --
170 * 7. ** if install failed **
171 * 7a. prompt_and_wait() shows an error icon and waits for the user
172 * 7b; the user reboots (pulling the battery, etc) into the main system
173 * 8. main() calls maybe_install_firmware_update()
174 * ** if the update contained radio/hboot firmware **:
175 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
176 * -- after this, rebooting will reformat cache & restart main system --
177 * 8b. m_i_f_u() writes firmware image into raw cache partition
178 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
179 * -- after this, rebooting will attempt to reinstall firmware --
180 * 8d. bootloader tries to flash firmware
181 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
182 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700183 * 8f. erase_volume() reformats /cache
