Can't get PS4 exploit to stick?

I ran the PS4 exploit on my 5.05 PS4 via http://crack.bargains/505k/ and used an app called PS4 Serve3 to load files for HEN, Mira, and other applications to the PS4 but for whatever reason, it just won't stick. I have to re-run the initial exploit every time the PS4 restarts and I can't access the files I loaded to the machine via the app. What can I do?
