Advice needed with recovering .3gp files

[betts]

Hi all, I have just installed and activated Recover My Files and need to retrieve some .3gp phone videos which were accidentally deleted from its memory card. I have managed to recover the video files, but can't get any of them to play. These are the error messages from my different media players:

Quicktime: Error-1856: an unknown error occurred (file name)
VLC player: Scroll bar scrolls all the way to the end quickly and no video is played.
Windows media: Windows media encountered a problem while trying to play this file.
Media Player Classic: Cannot render the file.

Is there another type of media player which will play these files in their current recovered state? Or do i need to somehow modify these files in order to get them to work.
Any help or advice would be greatly appreciated, thanks.

Hi,

How big is the memory card?

Please send a sample recovered file to support@getdata.com so we can examine the content.

Thank you.
