Had the same problems with my phone. I activated and updated to the latest OTA update (presumably 654.13). It was working, then it started dropping calls, no data, and the LTE error message. I took it to the store and they told me it's an HTC software issue, I'd have to just wait for an update. Not satisified after a week of not being able to use my new $600 phone, I decided to call and get an exchange. After some wrangling, they finally sent me a new one.
The new phone is on update 1.54.654.9, but it wants to update to 1.54.654.13. I shut off the auto download and decided NOT to apply it. So far so good. I can make and receive calls again, data and texting work great too.
My thinking is, 1.54.654.13 has the bug. With only the 1 phone, I'm not going to try it for now.
