Mine was also bricked a few days before yours, on the OTA upgrade. This is the second time this year it occurs. The last time was just before Easter, and I had to send the table back to HTC, and only got it two weeks later. It didn't cost me anything, besides a lot of patience and time, as I didn't have it rooted and it is still under guarantee. It is a great tablet, but these upgrades are flaky.
