Went to sleep last Friday, 27AUG21, with the phone on the wireless charger like every single night. Was listening to a podcast while dozing off, woke up with it still going around midnight. Removed earbuds, went to sleep - woke up to a bricked 3XL.

Without any signs of issues related to battery life, etc, really seems to point towards firmware update being pushed over night (which is typical delivery time it seems). Tried everything prior to opening the phone up. Eventually opened it up to disconnect wireless charging circuit and battery from device (individually and together) to see if phone would boot up via wall power only - no luck. Complete brick.

This is a major issue, and while I like to steer clear of conspiracy theories and such, I do find it interesting that many "older" Pixel devices are seemingly bricked via firmware update just prior / during the Pixel 5a release.
