I bought a used firestick from a friend ….I'm using the firesrick remote app on my Android for my firestick because she had lost the original remote …but I got a new WiFi network and I can't get into my firestick because it isn't the same WiFi network as the previous one it was on…how can I get my remote on my phone to pair to my firestick so I can get in and factory reset my wifi and reregister the whole system into my name and email and account
