When you have done one corner, you need to only use U and U' to move the next incorrect corner into the FRU position.

You can always refer back to the notation page to see exactly what that looks like. Remember that D is turned clockwise as if you were looking directly at the down face. However, there are some common errors that you can definitely look out for: I'm very sure that the instructions are 100% correct, so go through it again, and read it really carefully. Step 7 is certainly the most troublesome step, so it's the one I've rewritten and edited over and over again. You know what you're doing now, and you're really close to the end! Q: Step 7 of the beginner's guide doesn't work! I'm applying the algorithm correctly, and my cube is definitely solvable! What's up with that? If you came here from step 4 in the beginner's method, don't stop now! You may have just reassembled your cube in a solved state, but scramble it again and go through the four steps again. If you can't reassemble your cube in a solved position, you may have to peel off some stickers and put them back in the correct place. You can then reassemble your cube in a solved position. There are countless videos on YouTube that show this procedure, if you want to see it done first. The correct way doing this is to turn any face by 45 degrees and wedge your thumb/something else stiff under the exposed edge piece, applying force to pop it out. Then your cube is unfortunately unsolvable. Nevertheless, if your child, annoying friend, or jilted former lover somehow got hold of it and ruined it for you, you probably won't find out until you get to the third layer. But you wouldn't have done that, because that's cheating.

Obviously, rearranging the stickers is similarly not good for it. If you disassemble and reassemble a Rubik's Cube randomly, you have a 91.6% chance of making it unsolvable.

Q: How do I check if my cube is unsolvable? How can I fix it if it is? Check the contact page if you want to send me an email, or leave a comment at the bottom of any page. If it is solvable, it's entirely possible I've just made a mistake writing it down. If it still doesn't work, check to see if your cube is even solvable, which is the next question. Remember to turn the face as if you are looking directly at it! Sometimes people get confused with their Bs, B's, Ds, and D's, so check the notation page to see if you're doing each move correctly. That isn't a question, but if you're having trouble getting an algorithm to work, the first thing you should do is check if you're performing it correctly.
