In order to to the nether you need a portal.
A Nether portal is an obsidian structure that can transport players to or from the Nether dimension. USB doesn't come into it anywhere. The 'Minecraft USB nether portal' is just a YouTube fake.
only if you have this mod that gives you blocks like the mob spawner or what you want a nether portal
In single player, an unlimited amount of Nether portals can be made, although if you get to a really high number they may lag your game.
The get to the Nether in minecraft, you need at least 10 obsidian and a flint and steel. You need to make a Nether Portal, a 4x5 portal, and set it alight with the flint and steel.
I'm afraid you can only make water portals with the Aether mod. To make an Aether portal with the mod, you make the same structure as a Nether portal, but out of glowstone, and empty a bucket of water into on of the bottom spaces in the portal frame.
Make a nether portal.
The Aether is part of a mod for Minecraft; to explore it, you must first install the mod and its prerequisites.Once you have installed the mods, you must build a portal to the Aether. This works the same as a Nether portal, but with different materials. Build a rectangular frame four blocks wide and five blocks tall with glowstone, and pour a bucket of water into the middle of it. This will create an Aether portal, which can transport you to the Aether dimension in a similar manner to the Nether portal.
There are 2 portals you can craft in Minecraft. The Nether Portal and The End Portal.
