Clean boot
Warning! You should only perform a clean boot when all other
reset options have failed to restore your smartphone to an
operational state.
A clean boot will restore your smartphone to the factory
settings.
Warning! This will erase all your personal information, any contacts
stored on your phone and any programs you installed.
If your screen is responding to stylus input: Go to >
Default Settings. Read the warning information and enter the
security code in the empty textbox. Tap OK to proceed.
If your screen is not responding to stylus input: press the
Power button and Start key at the same time. When you see
the clean boot screen, press the camera button to proceed.
