I've yet to see a "HK" or "Original M8" etc etc description for a Rom. As stated previously, they are the exact same phone; 831C. There's even been a Sprint repair technician who did an open casing comparison of the two and found only different labeling on identical hardware. So long as you stick to Roms found within this sub-forum (Sprint HTC One (M8) ) you can rest assured you'll be getting full compatibility with your device.
