Fixing iMessage and Facetime

I need help fixing iMessage and Facetime, I already did everything I could via the dortania guide such as Fixing rom, generating new serial numbers. checking en0, resetting nvram, etc. But after all that, it's still not working, and I'm using an Apple ID that's not new and it has other apple devices linked to it.

I was wondering if anyone knows other things I could try?
