I have a MacBook PRO earlyPro Early 2011 and iI had it with High Sierra OS, as imI'm going to sell it i tryedI tried to revert to factory settings via recovery... the thing is that it shows an error and didintdidn't install it.
I was touching stuff in terminalTerminal following some guides iI found online and i makeI made things worse, the thing is that now the Mac only boots to internetInternet recovery, and when i try to install MacOs lionmacOS Lion (the only option iI have in recovery) it shows an error and doesntdoesn't download.
i tryedI tried to make an USB bootable USB from windowsWindows with Sierra OS but the Mac doesntdoesn't see it (iI used transmacTransmac because i dontdon't have access to another macMac to make it from there).
The other thing that i dontI don't understand is that when iI use the disk utilityDisk Utility to erase the disk it doesntdoesn't show "HFS extended journaled"Extended Journaled", just "macos plus case sensitive"macOS Plus Case Sensitive, encrypted"Encrypted", etc.
imI'm truly desperate, i dontI don't know what to do.
Sorry for my english.
