(adsbygoogle = window.adsbygoogle || []).push({}); This is NOT a full fix, more like a semi-fix. Most PSN features will be bugged asf like the friends feature. Proven to be working on CEX and DEX.

So, I basically found a possibility to get online with older firmwares, i.e. Rebug 4.65 after the "protocol patch" of the spoofers (which isn't actually a patch, more a change to the servers due to security reasons). I do not know what this option exactly does as I did not found any information about it on psdevwiki.
However, it will allow you to get online on DEX firmwares. Please note that you won't be able to use the DEX Debug Menu.
Tested with Rebug 4.65.

1. Spoof your firmware to 4.66, just how you did it back then when spoofers worked.
2. In Rebug Toolbox, change the Debug Menu Type to CEX QA.
3. Quit the toolbox, go to the settings and scroll to the very bottom.
4. Press the buttons: L1, L2, L3, R1, R2, R3, DPAD_DOWN at the same time (!)
5. Open the Debug settings which now appeared.
6. Change the setting "Nav-only NP" to On.
7. Login.

As said, I don't know what this option exactly does. I just played around with the NP environment to see if you can get online by changing the NP settings, and it worked. If anyone could explain what this option does I'd be glad and add it to this post.

Sorry if this was already posted, did not found it anywhere on the internet yet. Only semi-fixes where changes to the flash files are needed.
