When I start up macbook pro 2017 15inch in internet recovery mode,
pressing ((shift+) option+command+R), error message (apple.com/support -3403F) appears and can’t operate any more.
This error appeared at first after installing macOS 10.13.2 release version on December 7th.
After this error message appeared first time,
I have never succeeded in starting up in internet recovery mode ((shift+)option+command+R).
I was told by apple specialist that “This error may be network error, so try other network.
So I tried starting up in internet recovery mode in Genius Bar in apple store in Tokyo
by using Wi-Fi network of apple store. Then, the same error occurred.
Do you have any advice?
