how to bone stock to darkslide 4.2?????

[01dmax66]

Hello all I have read all kinds of instructions over the past couple days. My phone was stock and I wanted to root so I used Z4(super easy). So the next step was a rom, I wanted to try darkslide 4.2. I followed steps using bootstrap etc and when I tried to install it froze up on installing updates. So I battery pulled and it locked up on Motorola symbol. Anyway I sbf'ed it and was hoping someone could help me do it right this time. I Live in Alaska so Im not fully activated but have phone and use wifi for internet. Thanks for helping another noob. Also should I have done 4.1 prior to 4.2?
