@nightranger: I'm sorry to hear that you've experienced this issue. Based on the nature of your query, and the troubleshooting steps you've attempted, I recommend reaching out to our Help Desk on 0333 000 0333, or on Facebook or Twitter, where an advisor will be able to arrange an engineers inspection for you. In the meantime, try connecting the phone to your official charger before booting the phone up to see if this helps at all. You also have the option of factory resetting the phone from the recovery menu to return it to its default settings, however please be aware that this will remove any personal data from the device.
