93 * /cache/recovery/intent - OUTPUT - intent that was passed in
94 *
95 * The arguments which may be supplied in the recovery.command file:
96 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -070097 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080098 * --wipe_data - erase user data (and cache), then reboot

Oscar Montemayor05231562009-11-30 08:40:57 -0800100 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

105 * These important scenarios must be safely restartable at any point:
106 *
107 * FACTORY RESET
108 * 1. user selects "factory reset"
109 * 2. main system writes "--wipe_data" to /cache/recovery/command
110 * 3. main system reboots into recovery
111 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
112 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700113 * 5. erase_volume() reformats /data

The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800115 * 7. finish_recovery() erases BCB
116 * -- after this, rebooting will restart the main system --
117 * 8. main() calls reboot() to boot main system
118 *
119 * OTA INSTALL
120 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700121 * 2. main system writes "--update_package=/cache/some-filename.zip"

124 * -- after this, rebooting will attempt to reinstall the update --
125 * 5. install_package() attempts to install the update
126 * NOTE: the package install must itself be restartable from any point
127 * 6. finish_recovery() erases BCB
128 * -- after this, rebooting will (try to) restart the main system --
129 * 7. ** if install failed **
130 * 7a. prompt_and_wait() shows an error icon and waits for the user
131 * 7b; the user reboots (pulling the battery, etc) into the main system
132 * 8. main() calls maybe_install_firmware_update()
133 * ** if the update contained radio/hboot firmware **:
134 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
135 * -- after this, rebooting will reformat cache & restart main system --
136 * 8b. m_i_f_u() writes firmware image into raw cache partition
137 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
138 * -- after this, rebooting will attempt to reinstall firmware --
139 * 8d. bootloader tries to flash firmware
140 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
141 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700142 * 8f. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800143 * 8g. finish_recovery() erases BCB
