[Q] Which ARHD ROM variant to install?

Hello all, I've been following the M8 forum for a few weeks in anticipation of getting a new phone on May 8th. I have a bit of a noob question though, one that I've been unable to find the answer to myself.
Which version of ARHD 5.0 should I install on a T-Mobile HTC One M8? I've been following their thread for a while and intend to unlock/root/install ARHD within a few days of getting the device. I see mentions of the international version as well as different versions for each US carrier. My understanding is that GSM carriers can install international versions whereas CDMA carriers must install their specific variants.
If my understanding is correct and you are able to install the international version or the T-Mobile version, then what is the difference?
I appreciate any help. I'm not a complete noob when it comes to rooting and flashing roms, but I'm coming from a VZW Galaxy Nexus where it was pretty much idiot proof. I've been running the same ROM for so long that I know exactly how to flash it each time a new update is released. It didn't have specific variants because the ROM was designed specifically for the VZW Gnex. So I'm a little confused by the different variants and want to make sure I don't mess anything up a week after I get the phone.
Again, thanks to anyone who takes the time to help me wade through my confusion.

You can flash any GSM variant.
The differences will be whatever the carrier has done to tweak their version of the roms, included apps, tweaked settings, signal icons etc.

Thank you for confirming that. While I was like 90% sure, it's better to have someone confirm that for me.

Rogers is a GSM carrier .. nearly all the roms in the M8 international forums will work fine on your device
it's a good idea to update the software OTA fully before you begin the bootloader unlock / custom recovery / Rom flashing

Would that be the same for the samsung galaxy s5? If it's from rogers cause it seems like s5 has alot of models etc

The s5 has locked bootloader

So does that mean if I want to get back to flashing Roms and having the most opportunity, I should get a m8?? Cause the compaptability of Roms with s5 is limited with model??(GONNA assume that's what locked boot loader means)

Aside from ROMs specifically intended for CDMA variants (Sprint & Verizon) and dual SIM variant (if there are even any ROMs) any ROMs meant for the M8 can be flashed on your Rogers variant.
Aside from the exceptions listed above, the M8 versions are identical in hardware, aside from minor cosmetic differences like carrier logos.
You might need to update your firmware to run the current ROMs (s-off required).

So that is your software number for the unmodded, stock ROM?
If so, your firmware is current, and you should be able to flash any current ROMs (and probably older ones, too - but most folks usually aren't that interested in older ones) for the GSM M8. Just stay away from any ROMs that only specifically support the CDMA versions (Sprint and Verizon).
I won't say "without any issues" since there is always some chance of issues, even with the completely correct configuration. But I can say that you shouldn't run into issues related to outdated firmware.

yea i have the stock rom s-on

Yes. Make sure you pick "other M8 version" (or some such wording - just don't pick Verizon, Sprint, or T-Mobile) in the AROMA installer.

thank you my friend redpoint73

[Q] Newest AT&T (CWS__001) compatible firmware?

My AT&T HTC One M8 is currently running the WNC Lollipop ROM, radio/baseband: 1.24.21331147A1.09G and main/OS 4.16.1540.8. Is there a later firmware I should apply before moving to (e.g.) the InsertCoin ROM? Where do I find newer ROMs for the CWS__001?

Its a tricky question, as AT&T seems to be in the process of making changes to their LTE network in preparation of Voice Over LTE (VoLTE) deployment (HD Voice, as they call it) and this seems to be playing havoc for some folks on "Euro" based custom ROMs. Namely, not having voice call service or SMS while on LTEin some locations.
I'm also on the 4.16.1540 firmware, and its been working fine with SkyDragon Sense 7 on AT&T's network. And in multiple locations, as I just travelled to 2 different cities (in addition to my home market) and everything has been working fine on LTE.
All I can say, is try the desired ROM with the current firmware. If you notice any issue then try another firmware. I don't know if anyone has posted the latest AT&T 4.28 firmware, but you might check the AT&T M8 section for it, if you want to try it. I imagine the 4.28 firmware includes some AT&T specific radio tweaks. Although newer is not always better.

You should be able to flash any ROM intended for the "GSM" M8 (stay away from ROMs intended for Verizon or Sprint). Check the specific ROM thread to see if AT&T is supported, or at least if other AT&T users have tried it, if you want to be safe.
But as mentioned, you may or may not see LTE issues on some ROMs due to some AT&T network-specific factors. These issues seem somewhat isolated (maybe location dependent?) and I don't think any of the devs have had much luck addressing the issue. So trial and error is the best I can tell you.
