Accidentally erased the hard drive and operating system

In Internet Recovery, these low negative thousands error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.

Common problems include:

Hidden Network-name

required use of a proxy server to get Internet access

required use of a login page to get Internet access

Use of a login server or certificate to get Internet access

Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)

Use of Fixed IP address rather than good old DHCP

Variance of the time by more than five minutes

Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce -2002f]

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.

The higher the number, the more obscure the problem.

Also, make certain the Date&Time and Time Zone are correct within 5 minutes.

Hello,

What you have done is really erased the entire drive including the macOS that was on it. That is the reason you are getting the question mark at boot up. You will need to enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it. Ensure that you read the article above related to macOS Recovery Mode and follow the instructions to reinstall the macOS. You will need to be near a WiFi Network to download the macOS in Recovery Mode. Once you have installed the macOS then you will be able to boot into your MacBook Pro.

You may need to Reset NVRAM and then try Recovery Mode. If that does not work then Reset SMC and then try Recovery Mode.

Reset NVRAM/PRAM by following the directions applicable to your MacBook Air here ➔ How to Reset NVRAM/PRAM.

Reset SMC by following the directions applicable to your MacBook Air here ➔ How to Reset SMC.
