Diagnostic information preservation during installations of over the air update of wireless handset software

摘要

A method and system for failsafe preservation of diagnostic information that identifies problems encountered during installation of over the air updates of wireless handset software includes logging code stored in an area of the handset that is not updated during over the air updates and that is executable to generate and store diagnostic information in an area of the handset that is not updated during over the air updates. By disposing a logging code and diagnostic information in areas of the handset that are invulnerable to corruption during installation of over the air updates, diagnostic information is guaranteed to be generated by the handset and transferable to an external diagnostics system for analysis even in the event of a fatal error.
