I watched all the Nissan/Infiniti YouTube videos. I tried the same methods, unfortunately nothing worked. ...
Could you list these methods that you have tried so far?
Also, although not mentioned, I assume you do not have a spare key to try, right?
The codes point at the BCM, IPDM, steering lock unit or even the NATS antenna; although I am with the dealer in leaning toward the BCM being the issue.
That is due to the additional info you provided that the key blade being held in the lock position wasn't rolling the windows up yet you have good power.
To add:
This might not have any effect, but when you get a chance, inspect the
Eng Cont fuse in the IPDM. It's a 15A fuse.
