ICMP is the Internet Control Message Protocol which works at Layer 3 or the Network layer. It is used for all kinds of network messaging services utilized by IP, the Internet Protocol.

ICMP can also be used to relay query messages”
(see RFC 1256, if you are into that kind of thing).

Go to the website, look for the version that matches your platform and download. If you are using a Linux Operating System, VirtualBox is most likely in the repository of your distro.

It may have been what saved the phone. This is a very expensive phone and I was already bemoaning how I would have to shell out the money to replace it.
The internet, however, came to the rescue and I got a few pointers that I added to what I did to revive my phone.
