Flash RUU on HTC One M8 Windows 10 Insider Preview AT&T Branded to T-Mobile

Greetings. I've perused the forums for an answer and although I've found a lot of helpful information, I want to ensure I'm on the right path. I have an AT&T branded HTC One M8 Windows running the Windows 10 Insider Preview. I have no issues with the functionality and am pleased with everything so far. I'm wanting to install the T-Mobile RUU to get WiFi calling back and some of the T-Mobile utilities that come with the T-Mobile RUU. Since HTC provides only one RUU for each carrier, am I okay to assume that running the RUU utilities will have the same effect? I used ACDU with the T-Mobile RUU last night and got error 130 for the wrong Model ID. I've read about changing the MID and CID so I can spoof the settings but do all of the instructions apply to both the Windows and Android phones? I guess I'm asking do they use the same type of bootloader with it being OS agnostic.

Thanks for any help and information.
