My bold fell in the pool and it won't turn on anymore however i have sensitive files on there that i need to get hold of, is there any way to access the harddrive of the device although the it is damaged (ex. access pictures taken) ??
If the device won't boot then there's nothing. You could send the phone to a data recovery service although that costs serious dough but I don't think there's any retrieving them.
Is there a SD card in it? If so you can pull it out and the picture are likely on it. After a good drying with an adapter you can plug it directly into your PC or MAC and save the pictures on the computer that way until a replacement is found.
