A1502 / 820-4924-A. Unable to run diagnostics or recovery over internet.
Getting errors -1003F or -1003D shorty after inputting wifi details.
Runs Catalina & Big Sur fine. EFI updated to latest for the model (481).
I can register it with my iCloud / FMA.
Tried replacing the SSD, installing fresh OS, replacing wifi card.
Tried different 'internet routes' (APs). Tried disabling FMA.
Even stood up a custom AP where I can sniff traffic - macbook successfully looks up osrecovery.apple.com and connects on port 80 (dumping below some HTTP chatter). After these few requests it disconnects and above errors show up.
What gives? What else to try?
