I am selling one of my Pixel 7 and I was attempting to flash Google back onto it, something i've done three times before. Everything was going smoothly until the flash failed after downloading 2 out of 2.4gb. When the phone came back on, it was on the Graphene startup screen, so a factory reset was done. However, now my chromebook only recognizes the phone for 1 second at a time, and then it loses connection. Charging port definitely works because it recognizes a charger and a USB-C flash drive. I've tried 3 different cords (ones that have worked in the past) and my next step is trying a different PC but I'm open to any other suggestions.
