Note: Some third-party applications do not create a backup on your computer
when you synchronize. If you perform a hard reset, you may lose data in
these applications and you will need to reinstall these applications after
the hard reset. Please contact the developer to find out which
information is backed up during synchronization.
Note: If you do not see the “Erase all data?” message, the hard reset was not
performed. Please retry the above steps, making sure to hold
