Icloud restore photo stream?

I accidentally locked my boyfriend out of his phone using Find my IPhone a few weeks ago. Long story.
Bottom line is that he had to restore his phone. He had it back it up via icloud, but he hadn't backed it up using icloud since August. When he restored it via icloud, everything was normal except for his iMessage and his pictures. His iMessage wouldn't work all weekend, and finally after messing with it, it finally started working.

Although, his pictures still haven't loaded. They are on 96 out of 300. We have tried restarting his phone. Should we reset all settings and data? I don't want to have to fix his iMessage again, he just wants his pictures back.

I had the same problem… But it is because it doesn't load all photos
You should back it up in a pc, there it loads all the phone has
Hope it helps
