Do a scramble algorithm, then solve it into a different orientation

there you go

Just curious, are there any algorithms for 4x4 that do nothing but turn the entire cube around, without and cube rotations? also, no,"l'r" does not count, and neither does "L' R 2L' 2R". I mean an algorirhm that methodically swaps everything around

Uw2 Fw Lw' Uw Dw' Fw Dw' Bw2

Uw2 L2 R2 F2 B2 Uw2 L2 F2 L2 R2 F2 L2 F2 B2

Edit: (Uw2 L2 F2 B2 R2)2 is a bit shorter.

Uw2 Fw Lw' Uw Dw' Fw Dw' Bw2

Uw, Dw' ? what?

 

[ch_ts]

They're wide turns. Copy/paste them into alg.cubing.net.
Uw = 2Uw = u = U 2U
3Uw for 3 layers, 4Uw for 4 layers, etc.

 

[SpikeCuber]

no, think about it. if you are only doing wide turns, its essentially a 2x2. If u take a solved 2x2, and do a U followed by a D' .... they cancel each other out

 

[ch_ts]

If your question is like "Can you do an x rotation without using any of the L, 2L, 2R, or R slices?" I think the answer is no... I think you require either L or R, but you don't need the 2L or 2R slices.
Here is x', doing it in pieces:
[F e' F', D2]
[U: u2 f2 U2 2F2 U2 f2 u2]
[B2: [F e F2 e2 F, U2]]
[2D s 2D', F2] [U2: [2D s 2D', F2]]
[2B' e' 2B,U2] [B2: [2B' e' 2B,U2]]
[2B e' 2B',D2] [B2: [2B e' 2B',D2]]
D U F2 B2 U' D' R D U B2 F2 U' D' // used R
R' // used R again

edit: unless for R' you cheat like F' B U' F B' then fixed the edges...
edit2: in which case, R' can be done like this:
F' B U' F B'
[U: [U' s U, F']]
[B D': [e B' e', F']]
[U D' F2 U: [U F e F2 e2 F, U2]]

 

[SpikeCuber]

I don't care if you use slices, but the first reply to my original thread has a Uw Dw' right next to each other. Also known as: u d'. On puzzles with no center, d' basically just reverses u.

I KNOW HOW TO SOLVE THE 3X3X3 CUBE

Sometimes after making the cross I stumble upon this orientation. I saw my friend and he solves the cube with a different method, instead of making a cross, he makes the orientation i usually stumble upon

I'm sure there is a SHORT ALGORITHM to solve this directly...

 

[xyzzy]

It's a U perm, but I'm also not very sure what you're trying to say here.

 

[DGCubes]

The two algs most people use are either R U' R U R U R U' R' U' R2 and M2 U M U2 M' U M2. You can always find more algs if you don't like either one of those at algdb.net.

On the last stage of the 4x4 (PLL) there is a parity that I get every time (except once) I get either a Ua or a Ub. Instead of the normal two blocks on three corners and one full side on the back there is only one piece on three sides and a full side on the back. Please help.

I'm not really sure what you mean... can you take a picture?
Try: Rw2 F2 U2 Rw2 R2 U2 F2 Rw2

sigh. look up 4x4 'reduction', use that method, and stop trying to solve it the way you are solving it. Your life will be easier in the long run.

That is what i do

What way do you think I solve it?

If all of your edges are not in 'pairs', then you have not 'reduced' the cube to a 3x3 state prior to attempting to solve it like a 3x3

 

[SolveThatCube]

Here is the picture

You need to pair the yellow/red edge with the yellow/red edge and the yellow/blue edge with the other yellow/blue edge.
Look at the last case on this page: http://www.cubewhiz.com/4x4edges.php
That is the algorithm you need

yellow top, blue front: L' B' 2L' U2 2L' U2 F2 2L' F2 2R U2 2R' U2 2L2 B L

should work
