Jan 2015 this topic was posted (by ‘Ampulex’) but the discussion was closed Apr 30, 2017. I have the same problem with my FP1; after charging, the factory mode menu in chinese characters pops up. Taking out the battery doesn’t help. Navigating to ‘reboot’ (with vol down and power button) is impossible because the coloured line flickers up and down. What can I do?
