Rebooting Android

Gen4 to Android app

My Android app is in a reboot mode asking for zip code, WiFi/Ethernet etc. Note that my Roku - Tablo is working fine via WiFi.

I get to the install point where it warns about not having USB drive connected or it will be formatted. I have over 5TB of recording that I DO NOT want to lose.

It’s been a while - how do I proceed past this point without losing my recordings? TIA
