Hi! You could try to enter the recovery mode and do a reset of the phone: # Turn your device off. # At the same time, press the Power button and Volume down until your device vibrates. # Quickly release the Power button, but keep pressing Volume down, you will know when to stop if it goes well. To navigate through the recovery mode options, you typically use the Volume up and Volume down keys, and then the Power key to make a selection. Now navigate the menu and look for a reset option.
