"download dev": two-factor authentication error 412 when many trusted phones about ipsw

[blacktop]

412 PRECONDITION FAILED
One or more conditions given in the request header fields evaluated to false when tested on the server.

Can you describe more about what you were doing when you saw the error?

I don't understand:

When many (for me it is 6 phones) trusted phones used in Apple ID and used phone with non first ID download dev

Apple ID can have several trusted phones. My Apple ID have 6 phones. When I choose last one (with ID=6), Apple server (https://idmsa.apple.com/appleauth/auth/verify/phone/securitycode) return 412 code.
If I change code to:

json.NewEncoder(buf).Encode(&phone{
			Number: phoneNumber{
				ID: 6,
			},

(hard code ID=6)
and recompile ipsw, error disappear for this trusted phone.

Aww yes, I see what you mean! I need to support allowing the user to pick 1 out of many iDevices to choose from when entering the 2factor code!

It is already done in UI! But not working in backend... There is phone choose, but ID in POST method always equals 1.

This should be fixed in the latest release. Thank you for reporting! I vaguely remember when I first wrote this cmd that I was testing it so much that Apple flat out refused to send me ANY more SMS codes to my device and would ONLY do "trusted-device" push notifications. I also have only 1 device 😞 so I didn't notice this bug. Thank you! 👍
