112 * /cache/recovery/log - OUTPUT - combined log file from recovery run(s)
113 * /cache/recovery/intent - OUTPUT - intent that was passed in
114 *
115 * The arguments which may be supplied in the recovery.command file:
116 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -0700117 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800118 * --wipe_data - erase user data (and cache), then reboot
119 * --wipe_cache - wipe cache (but not user data), then reboot
Oscar Montemayor05231562009-11-30 08:40:57 -0800120 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

130 * 3. main system reboots into recovery
131 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
132 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700133 * 5. erase_volume() reformats /data
134 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800135 * 7. finish_recovery() erases BCB
136 * -- after this, rebooting will restart the main system --
137 * 8. main() calls reboot() to boot main system
138 *
139 * OTA INSTALL
140 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700141 * 2. main system writes "--update_package=/cache/some-filename.zip"

144 * -- after this, rebooting will attempt to reinstall the update --
145 * 5. install_package() attempts to install the update
146 * NOTE: the package install must itself be restartable from any point
147 * 6. finish_recovery() erases BCB
148 * -- after this, rebooting will (try to) restart the main system --
149 * 7. ** if install failed **
150 * 7a. prompt_and_wait() shows an error icon and waits for the user
151 * 7b; the user reboots (pulling the battery, etc) into the main system
152 * 8. main() calls maybe_install_firmware_update()
153 * ** if the update contained radio/hboot firmware **:
154 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
155 * -- after this, rebooting will reformat cache & restart main system --
156 * 8b. m_i_f_u() writes firmware image into raw cache partition
157 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
158 * -- after this, rebooting will attempt to reinstall firmware --
159 * 8d. bootloader tries to flash firmware
160 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
161 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700162 * 8f. erase_volume() reformats /cache
