There are several reset methods for the Memor X3. A warm boot terminates an unresponsive application and clears the working RAM, but preserves both the file system and the registry. A cold boot forces all applications to close and clears working RAM and files not resident on the persistent flash memory. Registry is restored from persistent memory if available or returned to factory default. A clean boot restores the Memor X3 to factory configuration: registry and file system return to factory default.
