For the arms, rotate the shoulders so that the "spikes" on top of them fit into the slots in the tan shoulder hinges. Extend the waist/push his head in, and then you can fold those tan shoulder hinges down. Now twist the forearms, and fold them up so that they grip the pegs on his back, behind the shoulders.

For the legs, twist his hips around (provided you have them oriented right in the first place, since they're backwards in the package). Disconnect the mammoth leg parts from the backs of his calves. Bend the knees 90 degrees, and manipulate the hips, so that the hinged bars that hold his front mammoth legs rest against his chest.

That's pretty much the bulk of the transformation. The rest of it involves clipping all the kibble together, which should be pretty obvious when all the parts are in their proper general positions.

 

Yeah, I just got Nemesis Prime and he was a real pain in the ass to transform. It would have helped if he came in beast mode or if the instructions started in robot mode. I had a hard time figuring out what was going on the pictures. I eventually figured it out, but man I was starting think I'd never get him into beast mode.

 

Yeah I agree those instructions were a pain in the butt. I eventually got it figgured out, but it took awhile...I think I've only actually transformed it maybe three or four times total. The bot mode is way better then the mammoth mode so, I don't think I'm missing out too much 

 

Man, I remember when I first got U. Nemesis prime. Took me like an hour to TF him. My girlfriend (at the time) was looking at me like, WTF?

 

Sorry, guys. I never understood the hype over Big Convoy's transformation, and when I finally got the mold in the form of Nemesis Prime, I found the transformation very intuitive - ten minutes on my first try.   I consistently get about five, six minutes these days, even faster if I go back and forth several times.

 

Me too, and I didn't even bother with the instructions. But that's just me. I think Alt. Grimlock's easy, too.
