I have a MacBook Pro Early 2011 and I had it with High Sierra OS, as I'm going to sell it I tried to revert to factory settings via recovery... the thing is that it shows an error and didn't install it.

I was touching stuff in Terminal following some guides I found online and I made things worse, the thing is that now the Mac only boots to Internet recovery, and when i try to install macOS Lion (the only option I have in recovery) it shows an error and doesn't download.

I tried to make an bootable USB from Windows with Sierra but the Mac doesn't see it (I used Transmac because i don't have access to another Mac to make it from there).

The other thing that I don't understand is that when I use Disk Utility to erase the disk it doesn't show "HFS Extended Journaled", just "macOS Plus Case Sensitive, Encrypted", etc.

I'm truly desperate, I don't know what to do.
