How I can get photos from my iPhone that has to be restored?

After a bad drop as in that case it’s not unusual some parts or even the logic board inside get damaged. When that happens even if the phone suggests to try a restore it’s only because it finds something is missing during the boot sequence, but it’s very unlikely the restore will change anything as software won’t fix hardware issues. Unless you’re inclined to run the risk of throwing money into random components purchase and replacement, especially if data inside is valuable to you, you’d better find a reputable lab into microsoldering who can test and fix the phone, that’s really the only way to recover your pics and data.
