Hi,

Anyone knows of an app that will allow me to recover my deleted photos,videos,music and other files on my HP Slate 7's internal memory using my PC? I have tried several android recovery tools however none of them seem to work. Tried Tenorshare Android Data Recovery, Wondershare Dr.Fone for Android and Recuva so far.

Your help is surely be appreciated for i need to recover important stuff. Thanks in advance.
