Root HTC One S has two versions (S3/S4)


Daleks Über Alles
Hardware wise, there are 2 variants of HTC One S. The 1.5GHz Snapdragon S4 MSM8260A (S4, or ville) and the 1.7GHz Snapdragon S3 MSM8260 (S3, or villeC2).

All T-Mobile USA devices are the S4. International versions may vary so make sure to check your device for which one it is.

There can be issues if you try to flash something meant for one variant to the other, so make sure that you only use a recovery/ROM/kernel/etc meant for your specific variant of the device.
