[2020] Can't update version 1.25 on PS4. Please help.

I recently got a PS4, and got BO4. When I go to update it, it obviously takes ages. When it gets to the end of the 30gb update, it shows a smaller update (I think it was about 6mb) and then does a few of those. A few small updates later, it freezes on one of them and says it will take +99 hours to install, the about 2 minutes later, it comes up with an error and says something along the lines of 'Cannot download update'. When that happens, it looks like it deletes the files. I've tried 4 times. Each time takes at least 10 hours (Internet sucks here), so I'm sure you can imagine my frustration when I've waited half a day and I watch as it comes up with an error and it's back to square one. Please, does anyone have a solution?
