Hello & Welcome to Just Answer,
Sorry to hear of any issue you may be having with your device.
In order to help, my I ask:
1) Can you CONFIRM the MAKE (brand) of your device?
2) The AGE of the device?
3) Has ANYTHING happened to the device (such as an update or being used by someone else) - since the last time you used it successfully?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
