Chosen Solution
So I just replaced my Pixel 6’s screen via the IFixIt repair kit (btw, this was way easier than expected, so that’s a win). However, I can no longer use the fingerprint reader. If I go to set it up I get an error message: “Can’t use fingerprint sensor. Visit a repair provider or g.co/pixel/fingerprintunlock”. That website was seemingly irrelevant and definitely unhelpful :).
Ok, so I fixed this. I had to go to this page: https://pixelrepair.withgoogle.com/udfps with my device in fastboot mode (turn it off, then hold down volume and turn it back on). Installing the software from there and then manually re-starting my device fixed the problem. However, for the above website to work, I had to use Edge (Chrome would also have worked as they’re the same browser under the hood, but Firefox did not work) and I first had to get Google’s USB driver from here: https://developer.android.com/studio/run… (unzip this somewhere). To install the USB driver, put your device into fastboot mode and connect it to your PC. Then open up Device Manager (Win+X=> Device Manager). Right click on your Pixel 6 and click “update driver”. Click “Browse my computer for drivers” and point it at wherever you put the driver. The driver should install and then you should be able to go to https://pixelrepair.withgoogle.com/udfps and install the software (don’t forget to reboot your phone once it’s done).
If anyone else has this problem and the above only partially works (for me it said fingerprint timed out), try restarting in safe mode. Hold power button and up/get to the “power screen” and then hold the power button instead of tapping. Then go to settings and re-register the prints. Worked just fine after that.
