Impossible. Herobrine is a creepypasta / community myth (2010). He has never existed in any official Minecraft codebase.
/summon herobrine does not exist.The myth originated from a doctored screenshot + 4chan /v/ thread. Mojang officially denied existence; "Removed Herobrine" patch notes are a running joke.
Enjoy the actual game: Redstone, building, survival, servers (via Bedrock on newer consoles).
