Hey,
I think it is not possible to recover the files stored in the internal memory of HTC phone. In order to recover files from external storage device i.e from SD card, you need to make use of an Android recovery software. The one that I would like to recommend is Yodot Android Data recovery software. This software can recover files from htc one, desire v, sensation etc. Just download its trial version to know more
