Phone [Q] Photos lost suddenly on GT-N7105

Hi Guys,

I am using Samsung Galaxy Note II (GT-N7105) and it upgraded to 4.3 for a while. I found all my photos suddenly lost in my DCIM folder which stored internal storage, I never do any deletion, no idea why all the pictures gone. The worst is I never do backup.

I did some research from here, most of method to recover needs to root the device, I am afraid if I root my device now, it may affect the chance to restore.

May I know any of you experienced the same or similar and tried to recover after root the device (never root the device until picture lost)?

I also tried all recovery tools downloaded from net, all applications couldn't recognize my device as Hard drive.

Hope any of you can help with it.

Cheers.

Thank you!!!
