Help with ripping X8

So I wanted to rip the model of X8's armor for X by following Demonboy's tutorial. Only problem is that I can't use 3DS Max on my computer, and the 3D program I use doesn't have some of the tools that 3DS Max has like vertex weld modifier and the normal modifier.

I've already scaled the UVs to fit the textures so if someone with 3DS Max can help me with this part that'll be great.
Also, if it is not too much trouble, could someone also T-Pose the model? Because I am absolutely terrible at it.

Here is the obj file
