iPhone Error 23. How to extract my photos in the iPhone?

Hi,

My iphone was charging and the auto-update function kicked in and it hanged. It gave the error 23 code and there is no way to reboot the phone unless I connect to iTune and do a reset.

My question is, HOW CAN I RESCUE MY PHOTOS IN THE PHONE, as I learnt that a factory reset would erase all data on the phone, including my photos. I have photos of my brother who passed away and it is something that we are not able to let go. I really hope to be able to recover my photos and have kept the phone till now. It was since 2018.

I appreciate any help and guidance.

Sincerely,

Adrian
