Urgent - iPhone disabled, rescue data

I have the iPhone 6s of my grandma here. She asked me if I could recover the photos she has made with her iPhone after it disabled itself for some reason.

I have already updated it multiple times over the recovery mode with iTunes. If anybody has any idea on how I could solve this quickly, I would be forever thankful. I believe my mother would love to have some of these pictures as well.

If you've restored the phone once, the data is no longer on the device.

You (your grandma) would have either needed a backup via iTunes on their computer, or backups being made via iCloud.

If you plugged the phone into her computer and there weren't restores available, and the iPhone setup phase doesn't say it can restore from iCloud, there's no backups to restore.

However, phone backups and service data are two different things. There is a change that if you set up the phone and log her back into her Apple ID, her "live account data" (service data) would come back if they were being stored in iCloud via iCloud Photos.

Have you gone all the way through the restore process and Apple ID login on her phone?

It is not possible to recover any contents off an iPhone that has been disabled. The contents is resting in an encrypted state on the iPhone and is only decrypted by a key which is constructed by several parts, one of which is the lock code used when unlocking an iPhone. I will assume there was a lock code in use since for an iPhone to become permanently disabled I think the wrong lock code needs to be entered 10 times.

When you get the "iPhone is disabled, connect to iTunes" message on your iPhone, the decryption key has been permanently discarded and the same unique key can not be reconstructed by anybody, as the key is constructed the first time you set up the iPhone by, amongst other things, the random input from the microphone at the time.
