Initnalized the system in secret menu how to fix?

[garethm56]

Hi there, I unfortunately did the most stupid think and initialized the system in the secret menu in my Nissan fuga y51 hybrid with Bose (m35h Infiniti basically).

My ac is now stuck, logo bouncing around some hybrid information not showing (like fuel economy)
Wondering how I can restore it back? Was thinking buying a used av unit with same config (hybrid, 2012 and especially bose) - dont know if that would work.

Otherwise buy a vcxdiag se module and run consult to reprogram it?

Anyone with some guidance on this would be much appreciated. Thank you
