Can't activate Ps4 as primary but mine can?

Pe
- in PlayStation
3

I have been trying to find something for hours but find nothing. So it is so I want to activate my friend's ps4 as the primary only it does not work because whenever I press activate it means that another is already activated. The thing is I disabled everyone else, I even went to the website and it said that I didn't activate ps4 as the primary. Do not know what to do

Ab
