Stuck at boot after OTA update
Just found this thread because I was looking for the changes the update did.

I can't give you an answer you are maybe looking for of how to fix this, but just a question before:
How long did you wait?

My phone is not rooted but I noticed, that it took really long until the boot was over (got stuck at the htc boot logo like yours too)

I was waiting a little bit for about 3 or 4 minutes and then went away. When I came back it was finished. But for sure it took longer than usually.

Hope this will help you maybe.
