  1. When I turn on the phone it says: Setup Wizard. Then tells me about the EULA agreement. Then it says: This device was reset. To continue sign in with a Google Accunt that was previously synced on this device. Enter my email. I am not sure. When I get to a point for my phone number they want to send me a 1 time code, but I cannot get the code since the phone is locked. I can make 1 emergency phone call, can you get me a phone number for me to someone who can help me. PLEASE

    • Sounds really strange. I was never asked to confirm my number after resetting a device. I would try starting the device without it’s SIM card and see if you will be able to get into your phone now. If you are prompted to insert a SIM just use the skip button.
      Hope this helps!
