iphone8+ board configuration?

[akyora]

The board configuration on the iphone8+ should have D21AP and D21AAP, but they are grayed out and cannot be entered.
Also, when I press the read button, it does not reflect the configuration.
Is this an oversight?
Or is this correct?
Note that tsssaver requires you to enter this information.

The board configuration D21AAP actually doesn't exist, it seems that whoever put it into the iPhone Wiki was mistaken. Apple doesn't have any iOS versions for the board configuration D21AAP.

I understand.
Thank you.
