you cant make one on pocket edition because you dont have obsidian and flint and steel.
You cannot make a portal to the nether in minecraft Pocket editon, but you can in x box and computer versions
There are 2 ways to do it.
First way: Go down to the depths of the world and find some Obsidian. You must have a diamond pickaxe. Mine 14 of them, or 10 if you want to leave out the corners of the portal. I like the look of the full portal best though. The portal is 4 blocks wide and 5 blocks tall. Now get a flint and steel and light the inside of the portal. And there you go.
Second way: If you find an easy lava pool to access when you want, as well as some water (you can dig a 2x2 hole that's 1 deep and fill it up with water and you'll have infinite water) and use something like cobblestone to build a hollow cast of the portal and put in a bucket of lava then water. Repeat until you fill up the entire cast. Now remove the cobblestone cast with a pickaxe and light the inside of the portal with a flint and steel.
No, sadly you can not make an Aether portal on the Xbox Edition of Minecraft because the Aether is part of a mod. As of now, the Xbox Edition of Minecraft does not support mods.
Its impossible but in pc or xbox
The only portal you can make right now is a Nether portal. Same with the PC version. (without mods)
You can already make portals in Minecraft for Xbox and PC. In the new app they should already have them too.
to make a portal to heaven you need glowstone and put the water in it
Because your xbox can't handle the lag.
You can build a portal to the nether and the end. However, as of January 2013, you cannot actually enter the end in the Xbox360 edition. According to my friend, they are making an update for that later this month or next month though.
4J Studios hasn't put in The End yet but there's still portal frames (creative mode only)
No, nor can you in survival. The Nether Reactor of Minecraft PE is not the same as the Nether in the PC or Xbox versions. Nether reactors only work in survival (intentional)
I recommend deleting some of the things you dont need so that minecraft wont freeze often, but there is always another option, as in: Waiting for the next update!
Not yet. The version on the Xbox is lower than the one on the computer. The Xbox version is at Beta 1.7.3, and Nether Fortresses aren't in that version.
Yes MineCraft for Xbox 360 has been Updated so there are now Blazes in Nether Fortresses.
