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

The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800135 *
136 * The arguments which may be supplied in the recovery.command file:
Doug Zongkerd4208f92010-09-20 12:16:13 -0700137 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800138 * --wipe_data - erase user data (and cache), then reboot
139 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800140 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

147 * FACTORY RESET
148 * 1. user selects "factory reset"
149 * 2. main system writes "--wipe_data" to /cache/recovery/command
150 * 3. main system reboots into recovery
151 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
152 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700153 * 5. erase_volume() reformats /data
154 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800155 * 7. finish_recovery() erases BCB
156 * -- after this, rebooting will restart the main system --
157 * 8. main() calls reboot() to boot main system
158 *
159 * OTA INSTALL
160 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700161 * 2. main system writes "--update_package=/cache/some-filename.zip"

167 * 6. finish_recovery() erases BCB
168 * -- after this, rebooting will (try to) restart the main system --
169 * 7. ** if install failed **
170 * 7a. prompt_and_wait() shows an error icon and waits for the user
171 * 7b; the user reboots (pulling the battery, etc) into the main system
172 * 8. main() calls maybe_install_firmware_update()
173 * ** if the update contained radio/hboot firmware **:
174 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
175 * -- after this, rebooting will reformat cache & restart main system --
176 * 8b. m_i_f_u() writes firmware image into raw cache partition
177 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
178 * -- after this, rebooting will attempt to reinstall firmware --
179 * 8d. bootloader tries to flash firmware
180 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
