PV shifting

[Tw33ty]

Okay first of all i know how the rng works and ive read This Article (http://projectpokemon.org/wiki/Pokemon_NDS_Structure) over and over again. Well Ive wanted to use some of these Schiftings on my pokemon. Actually only ABCD shift works as its standarts. the rest come out as unkowns. SO now I wanted to know what part i am Doing wrong.

For example:

I call the rng and get as pid [ED075D97] ( i use this clal method: [pid][pid][iv][iv])

I shift it using BACD so i have [07ED5D97] and now? what do I do next? or is even this step wrong?

Thanks in advance

Nvm I figured it out
I used 4 rng calls instead of 5.

Well but i wonder now what exactly makes the algorythm restricted?

Restricted is made by only certain seeds being used.
