hi there im a little baffled at this i was sending a text then all of a sudden my screen just went blank tried holding down volume down key and pressed the power button at same time. and tried both keys up and down at same time still no joy only got a ever so slight of a flicker as in white then never returns . even if i timed it right never works. it worked for me in the past it came up with 3 androids then pressed reset but not now . if any help could be achieved i would be ever so grateful i only get the front 4 little icons on desire hd nothing else no light on touch screen i hear phone rnging and hear textes but cant see a thing .
