No not yet. Honestly, I dont know how. However, I believe my son may have messed with the center pieces. I found them off of the cube yesterday. I put them back perfectly. I do know how they could be messed up. Its yellow on top, white on bottom, and (from left to right) blue, red, green, and orange.
Aaaah, sounds like that's where the problem happened. I suggest cycling the centers in the order @xyzzy suggested. Cycling four centers like that actually causes parity with the edges, even though the centers themselves are correct relative to each other.

Hello! I am here because I need help with my cube, i need 2 edge pieces switched on them. Only 2 of them need to switch but the other sides are all finished.

I’ve been solving my cube with no issues for a long time, but today I was playing with it and suddenly this yellow piece appeared to be out of place when I’m about complete the yellow side. I tried scrambling and solving it again around 10 times and it doesn’t seem to go back to normal, what should I do? Thanks!

You have an unsolvable cube because of a corner twist. The only way to make it solvable is to twist the corner back so that yellow is solved.

So my friend gave me a megaminx and I kind of know how to solve it so I’m just checking if he pranked me cause this has happened before lol

Yes I’m know some of the tiles have peeled off but I was just going to use a pen or somethingimage.jpg

The grey and blue edges are swapped but I don’t think it’s legit soo I’m just checking with some more experienced peoples

You can't have just two edges swapped on a Megaminx. Although, if certain tiles are missing on the other sides, it's possible that you've swapped two other edges without knowing. (Imagine if the blue-orange edge was missing the orange tile; then you wouldn't know whether the blue-grey edge and blue-orange edge are in the right places or not. You can solve it if there are two sets of two swapped edges.) If that's not the case, you'll just need to take the pieces out to solve this case.

Hello, I'm new to cubing.
I bought a new cube and was able to solve it with some tutorials.
However, I made a wrong movement, so that one edge came out. I think, I put it wrong together, because I'm not able to solve the cube anymore. When I try to solve my cube, I get the following error:
This configuration of the cube is not solvable, please check that you've entered all pieces correctly.

This is my cube. As you can see, I can't solve the last layer anymore:

Is it possible to find out, which piece is wrongly assembled?

Hi! I just started cubing yesterday and I've solved my cube by following the guide a few times already and have memorized/understood the first layer and parts of the second. My issue is with the last layer and particularly an unbranded cube I was gifted after someone won it at an arcade. I can't figure out how to complete the yellow cross without messing everything else up and the algorithms I've tried just put me in a loop. I have a yellow in the top layer on the side and I can't get it on U without messing something for the life of me. Any suggestions/help are appreciated. Thank you.

Assuming your first two layers are fully done, then you do have an impossible case. After the first two layers step, you will always have 0, 2 or 4 edge pieces of the last layer correctly oriented (yellow side up in your case). With exactly 3 edges oriented you'll be stuck between having 1 and 3 edges oriented. This means one of your edges has been flipped (either physically removed from the cube and replaced upside down, or its stickers were swapped). This isn't something you can really do accidentally, so maybe was done by the person from whom you got the cube. You'll need to pop out one of the edges, flip it over and reinsert it.

I know it's a late response, but...
you just have to flip an edge then you can solve it normally
