Q: error 2002F

Cannot connect to wireless from internet recovery

That error code is not publicly documented. It seems to mean that the Recovery system was unable to reach an Apple server. Sometimes that's because of a problem in the local network, but maybe sometimes it's beyond your control. I suggest you try connnecting to your router with an Ethernet cable instead of Wi-Fi.

how do i only use the ethernet cable when it only asks me for a wifi pasword

Turn off WiFi and connect the Ethernet cable

I am also having this same problem and can not turn wifi off...it is the only option allowed for recovery...I am beginning to hate apple

If your Boot Drive is not responding, then Recovery mode (which boots from a small, separate partition on the Boot Drive) may not be available either. That can cause your Mac to attempt to use Internet Recovery, and will usually display a spinning globe.

--------

Internet Recovery tries to get the Utilities need for recovery (and re-download) from the Internet, and present them to you. Internet Recovery (if your MacBook Pro from after about 2011 has that in its Firmware) has a set of strict requirements, especially concerning the setup of your Wi-Fi Network.

-2002F is said to be a Network error while trying to connect to an Apple server.

This article lists most of the attributes of your Wi-Fi network to make the connection. In addition to these, the Network-name can not be hidden.

What makes you think that wifi is only allowed? I have used Ethernet on my 2009 Mac Mini since wifi is slow.

You should connect Ethernet before booting to Recovery

Too all the people out there getting this "2002F" error, i have a solution for people in Australia.

I recently replaced my mbp 2012 hdd with a new ssd and was getting this error for over a week.

i changed the DNS setting on my router from 0.0.0.0 to googles public DNS 8.8.8.8

woohoo ! internet recovery worked instantly for me

Apple has moved the specific requirements for a Wi-Fi network to be used with Recovery out of the document I cited, and into this document (which is linked to the original):
