Hi have just purchased a B3-A40FHD for my wife from argos. On starting the tablet up for the first time it asked for the usual log in detail and I created a new account on google. Account sorted and to cut a long story short booted to the main screen. Shutdown the tablet due to going away. Came home and the tablet rebooted into safe mode and is now asking for the Google account detail saying with the screen in the pic. I have been trying to sort this out since the 21st of Jan 2018 and have been giving the 24hours sometime leaving it 47hours but I still can't get the device to work. I would appreciate any advice please
