one x+ sense 5 update irrevocably froze my phoneexactly

So my beloved ONE X+ finally was notified of the ATT {HTC} Sense 5 update yesterday (Jellybean 4.2). YEAH, right?!? I've been awaiting and anticipating this, seeing as the rest of the world had already been privileged with the update.That being said, I agreed to the update, left the phone downloading the update, and came back to a completely, seemingly irreversible, frozen phone. It will not power off at all, simply keeps restarting, and stays in that perpetual state of resetting and then staying stuck on the "HTC ONE" screen, which completely drains the battery, even while plugged in. I can not access the settings menu, so researched hard and master resetting on line. Figured it out and attempted to both recover and factory reset, neither of which work. The phone is perpetully stuck, and the models battery can not be removed; an easy fix on other models. I did, of course reach out to ATT who had me do the same things I had formerly researched and performed in repetition, and again to no avail. I see that another poster ran into a similar problem. Being that the phone is 1+ yrs. old, no warranties apply. I can not believe that there is no fix here. Anyone with any other ideas out there? I love my phone and have never had any issues with it in the past. Not sure if I am even posting this in the right category, but none listed seemed to exactly apply.

Thank you, in advance, for any and all assistance,
