Hi there, I recently bought a manufacture refurbished HTC One SV. Came brand new in box with all of the cables etc in original packaging and it was unlocked to any network. Only used this phone for a day and it decided to die on me: Prior to this i did close multiple apps, from the selector screen button (where you flick them to close them). I went on to my music and tried playing a song from the 'Artist' section and it froze up on a black screen, only with the top menu bar visible. Waited a couple of minutes, and tried pressing back as well as the power button but it did not respond. When i tried to turn on it started up but froze on the initial 'HTC' white screen and will not go any further than that. It had approx. 90% charge, and was on charge at the same time. I have tried the "Volume down+Power button" and tried all of the options on there, however none of them seem to work unless i am missing something. Hope this makes sense, as my family is completely stomped by it, and had to write this quickly as I have to work a night shift. Thank you in advance and happy new year.
