Thank you so much!

You forgot to attach the attachment :P.

Oh, yea! Fixed

Great job, I wanted to give you a tip ... during the flash plus choose these frequencies -25, -50, -75,-100mV, add -12.5, -37.5, -62.5, -87.5 mV ... I say so, because even on "System Tuner" and other programs for non htc device Scaling is 12.5 mv Good job and thanks again for your Mod!
