Decipher Backup Browser can help you view photos stored inside of Photo Vault by accessing the images stored inside of a backup made with iTunes. This is also handy if you forget your Photo Vault passcode/pin or if you need to recover Photo Vault photos from a backup.
- Download and run Decipher Backup Browser.
- Click on the backup that contains your Photo Vault data.
- Click Photo Vault.
- You'll be presented with a gallery of all of the photos stored within the Photo Vault app. Press "Save" in the upper left corner to save the images and videos, or click on individual thumbnails to view the full size photo.
