Lost photo Recovery when syncing iOS with itunes

Because there is no backup, after using the sync function, found that the photos were emptied, find the recovery method, share!

Everything is fine except of one thing-there are nothing on the camera roll!

If I go into IFunBox I see on the side to icons of camera:
Camera
Camera 2

If I go to/var/mobile/media/dcim I see
100APPLE folder
101APPLE folder

And I never had the 101APPLE before.
Anyway all my pictures and videos is on 100APPLE folder, so I backed it up.

Now, how does I get back all the pictures and videos to the camera roll?

Thanks.

To solve it delete this files:

/var/mobile/media/photodata/photos.sqlite
/var/mobile/media/photodata/photos.sqlite-shm
/var/mobile/media/photodata/photos.sqlite-wal

Restart and thats it.

After the reboot, the photo is empty ... Please wait for a while. You can refer to the links below
