My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Unfortunately, there will not be any way to retrieve the data and pics on the iPad. The firmware is in a corrupted state and will require a fresh install in order for the iPad to function properly again.
This sounds like you will need to restore using iTunes and you will need the iPad in DFU mode to restore.
Once in DFU mode the iTunes will not ask for the device to be unlocked.
Follow these steps please.
