The fastest way to reset to factory default android for your table Archos re-install android fresh

Turn the Archos off, Hold the VOL – button and turn it back on. Keep the Vol – key pressed. It will load into Archos Boot Menu. Once you see the white screen you can let go of the Vol- key. Using the Volume keys go down to Recovery System, hit the Power Key to select it. Select Repair System and or Format System… up to you. I’d try a repair if that doesn’t work Format it.
