Default How to go from RUU to latest OTA?

Well, I couldn't live without wifi calling. So, I recently ran the RUU on my TMO HTC One S from this thread: http://forum.xda-developers.com/show....php?t=2094414.

The software version is 3.14.531.11 710RD. I have another one of these and the latest SW build is 3.14.531.19 710RD, which includes the "heartbleed" fix. I want to leave it stock, but just get root back, but before I go through all the trouble, I'd like to update to the latest stock update.

I tried searching for updates through the device, and it just says "There are no updates available for your phone." I have all the options checked. I also checked HTC's site and they have my version instead of the latest OTA. Any chance HTC has just archived the updates and I'm SOL until someone posts the update? Any suggestions to get ahold of that update?
