Hi monique97, have you tried a Factory reset? I would suggest you Download the User Guide from Huawei. It's in PDF form and you can follow the procedure from the guide.
I'm thinking that you may have something corrupted and going back to Factory Settings may restore it. Cheers Neil.
If you go to this page and > Downloads > language (English) > select the user guide at the bottom of the list. I used Foxit Reader to open it and printed it out. Neil.
