Q: i have lost my all photos from my iphone 4s while updating to software 6ver. unable to restore from itones. help me how can i restore them.

There are two ways to have photos on the iPhone. First is the camera roll, these are the pictures you have taken with the iPhone camera. The second are pictures that are synced to the iPhone through iTunes from the computer you sync with.

The pictures in the camera roll are designed to by imported to the computer just like photos taken with any digital camera. They are not designed to be only stored on the iPhone.

If you imported the pictures to the computer or performed a backup of the iPhone prior to the attempt to upgrade software on the phone,all you need to do is restore from a backup. If you did not create a backup, you can look for the last backup you made if the pictures would have been included in that backup. Unfortunately, in that last case, you will also lose everything you have done since that backup.

If you have been backing up or syncing with iCloud, the pictures should be there.  If you have not done any of the above, the pictures are lost.
