It's so simple I don't know why I I didn't think of it earlier. Just let it download up to about 200mb then hit cancel, the launcher has a resume function so just start the download again, but this time it will start where you hit cancel! Do that every 200mb until you get past the patch that's giving you trouble, then if it happens again, just follow the steps again. I tested this on 2 PS4's. If you have any questions please send me a message on PS4 My Psn is Spook_em.
