Mike, unless you stored your files to a memory card (which only some version of the V3##) had access to, or transferred it previously to your computer, the information will be saved onto a memory chip on your logic board. In the case of the V3 it is a PF38F4050L0YBQ0 flash memory chip. It is only possible to retrieve it if you
1. have a flash memory IC reader or
2. have the knowledge to build one and
3. have the right software to read the information.
That is why professional services charge hundreds of Dollars to retrieve that information. Maybe you have a connection with some digital forensics expert that could assist you with that. If your logic board is viable, you might think about fixing your phone.
As long as the memory card in the phone do not be damaged, it is possible to recover data from your phone. Generally, most data of the phone ared saved in the memory card, thus, if you want to recover data from your phone, actually, you are doing memory card data recovery, you can learn more here: Motorola data recovery
Yeah,if the SD card is okay ,then you can retrive your lost photos easily,or we can say that part the memory card.
You can use some "Card reader" to see whether your pictures are still here,if not,you should use some special photo recovery software to find baxck you lost photos.
Hope this will help you.
