The link to the Google tool to get the Pixel 3XL phone to recognize the new fingerprint sensor only works for Pixel 6 and newer. Perhaps the tool accessed by the link previously supported the Pixel 3XL, but no longer does. Either a correct reactivation tool for the Pixel 3 should be provided or this guide should be taken down. As it stands, it seems useless to replace the sensor unless a way is provided to get the phone to recognize the new one. If there is an alternate way to activate the new sensor, the method should be provided in the guide.
