> When an SM with keyword START:install is received and there is a valid parameter set for the operation, the module always reboots either when the operation completed, an error occurred or the safety timer expired. If there is any error during an update operation the old application is kept untouched, with one exception. If there is not enough space in the file system to keep the old and the new application at the same time, the old application is deleted before the download of the new one, therefore it is lost when an error occurs.If install/update was successful, autostart is set to the new application.
