After recovering and deleting all the folders, my screen pop out a globe with an exclamation mark and error -2002F and I can't use cmd-R, so it stucks there. Any idea how I can fix this?

Globe with alert symbol

You might see a globe with an exclamation point when your Mac is unsuccessfully attempting to start up from macOS Recovery over the Internet. Your Mac might not be able to connect to the Internet, or it might be using a network configuration that doesn't work with macOS Recovery. Try these solutions:

• Use Command-R at startup to attempt to use the built-in macOS Recovery system instead of macOS Recovery over the Internet.
• Connect to the Internet using Ethernet instead of Wi-Fi, or vice versa.
• Connect to the Internet from a different network.
• Try again later, because the issue might be temporary.

About the screens on your Mac as it starts up - Apple Support

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. In the US, we just switched back to standard time a week ago, and if your system Time has not been updated since then, that could be the issue.
