If these are retrievable they have a Cellbrite or similar device to copy out such. If you were good enough to set the photos to save to the microSD card then you pull that and get them from there.
Not one counter does this for free. Figure 100 bucks if you are not buying a new phone.
PS. Google what that cellbrite is and does.
My mum has had her samsung GS3 for under a year and all of a sudden its just died, it'll go as far as the start up screen and thats it, we were about to send it away for it to be repaired, but they said they would wipe it completely and put it back to factory settings, but we have a some really important and sentimental pictures on there we desperately need to retrieve, and we were praying that there is some way we can do this??
I was sure I'd be able to view it as an external hard drive or something when i plug it into my computer but it doesn't even show up. If any one has ANY answers or tips, this would be so appreciated, we just want the photos back!
