Recover deleted photos on iOS 6?

I have a very old iPhone 3GS running 6.1.6. I recently accidentally deleted a few pictures from that. There are no iTunes or iCloud backups.

I tried using Aiseesoft’s Fonelab software to restore deleted files. I followed the on screen instructions. The iPhone enter recovery mode. It tells me: “Communicating with your iOS device for scan, please wait...” The progress bar is stuck at 0% for a few moments, before Fonelab tells me “failed to enter the scanning mode due to the loss of connection or timeout”.

Is there anything I can do to recover the photos? Either with Aiseesoft or other software?
