take some cheese (aka moonrock) (aka endstone) and stack up to the build limit and jump off. Then you'll be teleported to the end portal with 4900 eyes of ender and you type into the chat " Ender Dragon, sit!" and it will sit as you kill it but make sure to say, "good dog" before you kill it.

first you place down nether portals (wich you craft with 2 eyes of ender and 2 eggs) in the shape of a cow then you type all the censored words into the chat from a-z then you get a AK47 then load it with some TNT and launch it at the the sky right above your head then that summons the ender dragon wich will give you all the admin abilities then type in the chat /dino (insert your user name here) nethar then the portal is done ur welcome :)

oh and can you post a video of you doing i wanna see it

pleh, very easy
You just need to do a speedrun to complete 100% of Minecraft. Then, when you finish, you summon Herobrine (there are several videos on the internet on how to do this) and when summoned, ask permission to change the game mode to creative to get a frame pack for this portal, it's very easy. You'll have to fight him and that's it! Just enter creative.

I hope I helped hehe

You get some portal frames by mixing powder snow and milk then you place that in a 3 by 3 cube then ignite all holes with a piece of tall grass. by that point you should have a fire hazard, good! proceed to place another cube on top of the first, but this time fill all the holes with water. then place another cube on top, but fill all but the top and bottom holes with cobwebs. Congrats, you've just made a mess of blocks! And now this is the final step! place milk lanterns on each corner in a square on the of the top cube. An obsidian block should appear in the top hole. You have just lit the portal.



Do this but backwards and upside down :)

Make a nether portal out of end stone. Do not ask me how to get the end stone without an end portal

Build an octahedron of cobble around the spawner (the bigger the better, but max size is 15 euclidean from the spawner and remember to include dirt or wood ramps to allow access to the upper parts).
Stand where teh spawner is active until the entirty of the cobble has become infested (this does not need to be accomplished at one go.)
Standing on the upper tip of the octahedron punch the cobble (bare handed) until the infested block summoning the silverfish and opening the portal through which one should fall.

build a frame out of inside an and light it

put a statue of netherrack, gold blocks, and redstone torches on a cliff and sing a song about a mythical being called herobrine

Go to the nether, bridge out over lava at height 86. Build a frame with 9 gold blocks facing into the lava pool. Once done jump in.

You can very easily build an End Portal in Survival Mode from resources you gather in the game.
