I was downloading a mixtape and trying to transfer the songs onto my music player when it started acting funny, so I rebooted it to recovery. When that happend it restarted, went past the t-mobile logo screen then went to the htc screen and stayed there. It's been like this for the past hour. What do I need to do to get it back working? i just did a hard reset and it's still not going past the htc screen
