I had a critical system failure, so I went to a recovery mode using cmd+r. After wiping hard drive i wasn’t be able to use cmd+r again so my macbook tried to use internet recovery. No matter which network I’m using I always receiving -2003F error code. I’ve tried a wired connection, usb install, extrnal hdd etc. No effect, always -2003F code. Any idea how to „unbrick”?
Yes if you erase your drive you lose the Recovery partition and your way forward is Internet Recovery or if you made a bootable USBinstaller you can use that, reboot holding option key in that case.
The error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used to connect.
If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet or try a faster Network
Make certain the Date and Time plus Time Zone are correct within 5 minutes.
