Well, it's not an HTC One, but I'm using a Galaxy S4 with a custom (well standardish) i9505G ROM and sure enough, there's a bug that prevents LTE being picked up on the particular ROM I'm using. I had to download an App from the Play Store to force LTE on. (And then it worked great)

Can you advise what app you are using to do this? I have the same setup but no 4G.

Search google play for "LTE Setting" by Ryo Ueshima. I am not linking to it because apparently it can cause some level of brickage if you choose the wrong settings.
So, this post is NOT made as an employee of Telecom - it is made as an individual. If I was posting about this as a Telecom person, I would specifically be recommending against using an app like this.
I honestly can't remember what settings I chose... This is AT YOUR OWN RISK.
The best way to get LTE is to flash back a carrier image.
