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.

i managed to get it back up, i downloaded mac os lion 10.7.5 and i used transmac software to make a bootable USB drive with lion 10.7.5.dmg inside from my Windows 10 machine. Steps (on windows 10): 1- get MacOS Lion (in my case) 10.7.5 (not older, because if its older you wont be abble to update it to Sierra) 2- get transmac trial software (15 day trial) 3- open transmac as administrator 4- plug in USB drive (8GB or more) 5- on transmac locate the USB drive, click right mouse button and click "format disk for mac" 6-click "yes" 7-when it finishes formatting, click right mouse button again on the USB drive and click "restore with disk image" 8- search and select the Macos Lion.dmg file 9- click "yes" and wait until it finishes (it may take a while)
when i booted from the mac with the USB drive (push the power button on the mac and righ after push "cmd") it gave me another error and refused to install... after a lot of searching i found that reseting NVRAM may help, so it did (turn on the mac holding option (alt)+cmd+P+R), and after the long install process i was on MacOS Lion, and from there i updated to Sierra, and after that High Sierra.
Thanks to all for trying to help me and i hope my experience can help someone in the future.
