New Motherboard/CPU problems

[Azaqa]

So I recently upgraded to am5 mobo+cpu, it posts and boots but it made me clear tpm due to detecting hardware changes. Now it says "your pin is no longer available due to a change in security settings" when I click "set up pin" it asks me to sign into the internet, but its also locked in airplane mode. 

 

Im fine with factory reset but not sure how to do that either if I cant sign in. In bios I see "ASUS Secure Erase" but it seems their website is down for maintenance so I cant check the compatibility list to see if my SSD is on it (Samsung 970 EVO 500GB).

 

Any advice or solutions?

Ethernet still works in airplane mode. You can also tether your phone via USB and access internet that way (Only on Android devices).

 

You really should do a clean install once you are in by the way of creating bootable USB device.

I have powerline, which worked great pre upgrade. It was fairly slow (5mb/s or so) but very reliable and no stutter/lag. Im not sure why exactly but it just doesnt recognize it now. Ill try out the phone idea.

The phone tethering worked however now that im signed in  a bunch of apps are showing "remote procedure call failed", any way to fix this or should I just factory reset?
