80 * /cache/recovery/intent - OUTPUT - intent that was passed in
81 *
82 * The arguments which may be supplied in the recovery.command file:
83 * --send_intent=anystring - write the text out to recovery.intent
Doug Zongkerd4208f92010-09-20 12:16:13 -070084 * --update_package=path - verify install an OTA package file
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -080085 * --wipe_data - erase user data (and cache), then reboot

Oscar Montemayor05231562009-11-30 08:40:57 -080087 * --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

92 * These important scenarios must be safely restartable at any point:
93 *
94 * FACTORY RESET
95 * 1. user selects "factory reset"
96 * 2. main system writes "--wipe_data" to /cache/recovery/command
97 * 3. main system reboots into recovery
98 * 4. get_args() writes BCB with "boot-recovery" and "--wipe_data"
99 * -- after this, rebooting will restart the erase --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700100 * 5. erase_volume() reformats /data
101 * 6. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800102 * 7. finish_recovery() erases BCB
103 * -- after this, rebooting will restart the main system --
104 * 8. main() calls reboot() to boot main system
105 *
106 * OTA INSTALL
107 * 1. main system downloads OTA package to /cache/some-filename.zip
Doug Zongker9b125b02010-09-22 12:01:37 -0700108 * 2. main system writes "--update_package=/cache/some-filename.zip"
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800109 * 3. main system reboots into recovery
110 * 4. get_args() writes BCB with "boot-recovery" and "--update_package=..."
111 * -- after this, rebooting will attempt to reinstall the update --
112 * 5. install_package() attempts to install the update
113 * NOTE: the package install must itself be restartable from any point
114 * 6. finish_recovery() erases BCB
115 * -- after this, rebooting will (try to) restart the main system --
116 * 7. ** if install failed **
117 * 7a. prompt_and_wait() shows an error icon and waits for the user
118 * 7b; the user reboots (pulling the battery, etc) into the main system
119 * 8. main() calls maybe_install_firmware_update()
120 * ** if the update contained radio/hboot firmware **:
121 * 8a. m_i_f_u() writes BCB with "boot-recovery" and "--wipe_cache"
122 * -- after this, rebooting will reformat cache & restart main system --
123 * 8b. m_i_f_u() writes firmware image into raw cache partition
124 * 8c. m_i_f_u() writes BCB with "update-radio/hboot" and "--wipe_cache"
125 * -- after this, rebooting will attempt to reinstall firmware --
126 * 8d. bootloader tries to flash firmware
127 * 8e. bootloader writes BCB with "boot-recovery" (keeping "--wipe_cache")
128 * -- after this, rebooting will reformat cache & restart main system --
Doug Zongkerd4208f92010-09-20 12:16:13 -0700129 * 8f. erase_volume() reformats /cache
The Android Open Source Projectc24a8e62009-03-03 19:28:42 -0800130 * 8g. finish_recovery() erases BCB
