Bought a new Pixel tablet, took it out of the box, updated the system, did the OEM unlocking etc. Followed the directions exactly. Installing from Windows 11, brave browser with shields off. The flash is frozen on 'writing product..." The status bar is about 20% full and has been for over an hour. I'm baffled, and a little discouraged if I spent $500 on a device that will be immediately bricked. I've successfully installed Graphene on 3 phones, but this is my first tablet and I'm not sure what's wrong. Thanks for any help.
