Man, I am impressed that your device works at all with the above profile. DSP@600 and MPU@550 ?!? WTF? What are you trying to achieve with that? Of course it won't work with SR enabled. And 700 and 750 are deprecated, you should use 720 instead. Or best throw that profile away and use dsp with modified MAX frequency. EDIT: Just wondering what is your battery life with this profile. 6 hours?
