I think there is a software that you can recover your file from your android but i don't know if it can also recover the files of your wallet..
if your phone OS is android you can try to use the Dr.Fone i already tried to use this for a long time when i have some customers in my shop i used this tool and works fine but some times there are some files are already corrupted.. but most of the recovered are ok ..
Check this tool

if not working better to root your HTC first before you do this so that they can fully access your phone..
