How to reliably restore photos on iPhone 4S? I've been asked to help restore photos and videos from an iPhone 4S, after a reset. No iCloud backup. I see a lot of software that claims it can do this, and paying a fee is just fine. But does it deliver? Has anyone done this? 

Ideally, I would like to dump the user accessible flash to an image file and use tools like photorec and magicrescue to carve the JPG files out. The video files are of lower priority. 

What have all of you done to recover lost data on iPhones? 

Thanks!
iPhones are hardware encrypted. 

If you reset the phone from scratch, everything that was on there before is gone.
 Once the hardware key is erased, the data is not recoverable by any means. 

That's what backups are for.... iExplorer et al can scour backups &amp; the current phone system... but not encrypted, overwritten devices.
