So my phone took a dump and I had to reload it after this process I lost all of my files I downloaded wondershare and it was able to retrieve I think most all of my files but, I have audio files ones that I recorded for my wife during a Dr visit that are very important and I need them back but, even though I think I have the file it will not play says corrupted no code etc with various programs I have tried they are M4A file format and I need help getting these to play and I would be willing to pay for the help if someone can make them play again really need help with this one to get out of the dog house
