iPhone 4S: Unable to restore device with error -27. Anything I can do?

As per the title, am trying to restore an iPhone 4S that is stuck on the white Apple logo.
It has some photos on there I'd like to retrieve, I don't actually care about getting the phone to work again.
3UTools is failing under a DFU flash with error -27. At the time the restore process is saying 'Mounting filesystem' and is at 20%.

Anyone know if there is anything that can be done to fix this?

Thank you.
