you can't make the ender portal you have to find it in a stronghold made of stone bricks and put eyes of ender in the frame pieces. to find the strong hold you can throw eyes of ender in any direction and they will float towards the stronghold,try it in creative mode first because its really hard!
There are 2 portals you can craft in Minecraft. The Nether Portal and The End Portal.
In pure survival, it is impossible to make an End Portal Frame. If you encounter a naturally generated portal, you must place eyes of ender in each of the frames. An eye of ender is crafted by an ender pearl and blaze powder.
If you want to go to the end using this you can't the End isn't implemented.
120 is the Minecraft I.D. code for the end portal frame.
The nether portal and the newest one, the end portal.
The only portal you can make right now is a Nether portal. Same with the PC version. (without mods)
Place 3 End Portal Frame blocks on each side without corners, then place Eye of Ender in each frame to activate your portal. Note that, End Portal Frames cannot be obtained using Creative Mode and the give command. Mods will be required to obtain it.
You can't you need to find it in a stronghold :) Not true you can get it using tooo many items :)
4J Studios hasn't put in The End yet but there's still portal frames (creative mode only)
You have to put 12 eyes of ender in each of the portal blocks. Then, it should activate.
You have to find an End-Portal in a stronghold. The probablility of finding a stronghold with an End-Portal in it is small. Because there are 3 strongholds per map, and there is 1 end-portal per game.
You shouldn't be able to, first off. But if you somehow smashed bedrock and all the portal blocks, you have to die to leave the End.
