Maybe if you know how to do it
Whichever Herobrine mod you are using will say how to make Herobrine appear and what you can do what he does, each mod will be different.
no
you can't.
No. Herobrine is a myth. He is NOT, nor was he EVER, in Minecraft.
Herobrine's behaviour is determined by whichever mod you are using to add him.
No You Can't unless you have a mod.
It depends which mod you are using. Many mods add Herobrine, they all have different ways of summoning him or making him appear.
The great myth of Herobrine is hard to defeat. He can break through any type of block and he is apparently in creative mode able to spawn block.
You have to beat adventure mode. Then you will get survival mode
It depends which mod you are using. There are many different mods that add Herobrine into Minecraft, you'd have to look at each specific mod to see.
No, you shouldn't need to do that. Whatever Herobrine mod you use, should let him appear naturally, a texture pack won't change that.
Why is there no survival mode on iPod
