Earlier today i was listening to music on my phone whilst downloading a few apps. I put my phone down and it went into standby whilst playing the music and downloading the apps. I tried to unlock the phone but no screen would come up, yet my music was still playing and therefore i knew that my phone hadn't turned off for some reason. After the song had finished, instead of going onto the next one, the phone just did nothing. I took the battery out, left it for a few minutes (incase it was merely a case of the battery overheating) and put it back in. When i then turned my phone on it went onto the 'HTC' welcome screen and just stayed on it until i then took the battery out again to turn the phone off. I have done this many times since and i always get the same. I have tried to do the recovery but all i get is a black screen with a picture of the phone lying down with two green arrows forming a circle with a downward pointing arrow in the middle. My phone then vibrates a few times and that is it. Has anyone got any ideas how to resolve this?
