Does it have to do with the little bumps on the inner center piece?
Yes. The bumps on the opposite sides of the cube have to face the same direction.

The bumps are there to force the core to move with one side of the puzzle when you do a double-layer turn, so if you have bumps on both sides (which happens when they're not facing in the same direction), the cube will jam every time you try to do a double-layer turn.

Okay, the bumps opposite to each other are not all facing the same direction, but the bumps on my cube are stationary, so I don't think they could be the problem unless, maybe I have to unscrew it? I will try unscrewing them and rotating the bumps.

UPDATE:
Thanks @xyzzy,
It worked! The cube is a bit loose so the bumps kind of rotate on their own sometimes, but I will tighten that later. Thanks for the solution!

How many times have you tried? Usually tightening it a little helps you get past the first step. Try a few more times.

Is there a guide that tells how to pop 7x7 cubees back in place with little without disassembly?
Every 7x7 I get I like to tighten to the point where theres no popping, but lockups happen. This time I tighten a bit, but now a cubee popped out. I try to see if I can pop it back in, but you have to have to be like Catherine Zeta-Jones in intrapment where you have to know position, direction,when to rotate, etc. I've yet to find anyone knowledgable in 7x7 cubee info.

Big cubes are like that. Have them loose and they pop; have them tight and they either become slow or lock up a lot.

The two main solutions to this are to (i) turn more accurately or (ii) get one of the flagship cubes (Wuji or the soon-to-be-released Hays 7).

Has anyone figured out how to get a WuShuang back together without having to screw the final center into the core? I tried many ways with loosening the surrounding centers (where I'd be inserting the last 3x1 edge) but to no avail.

Any advice on how to separate the corner cubie of a 3x3x3 into its constituent pieces? Separating the halves of edge pieces has been easy so far, but I'm having a really tough time getting the corner pieces of my Little Magic separated in prep for magnet installation. Many thanks in advance.

EDIT: Tabe helpfully suggested using a plastic razor to gently pry the halves apart, which made the task ever the much easier. Thank you!

Hey everyone. Just yesterday i got a QiYi QiDi S 2x2 cube. It was amazing to use, it was smooth and super nice. Until one of the pieces popped out of the cube.I originally thought this wasn’t a big deal until i tried putting the piece back in. It wouldn’t go in and the core pieces popped. I put all of the pieces back into place and everything seemed fine. Until i tried to put the outer pieces back on the cube, they wouldn’t go in. I’m pretty new to cubing too. Please someone help :(

I had this same issue, but I just watched TCKyewbs' video where she set up the GuoGuan Xinghen, and that gave me a good idea on how to reassemble my WeiPo. Hope this helps!

Hey!

I just reassembled my wuque mini 4x4. It used to be smooth and was able to corner cut and lockups weren't an issue. Now all this is happening and I dont really know why.
Any help would be really nice.
