Help with Anduril

I have an original GT Mini. I would like to switch from smooth ramping to stepped. While trying to follow the directions I have, I can’t get past 3C. No matter what I try, I always get the battery check. Can one of you give me a step-by-step guide please?

Maybe your GT Mini uses NarsilM instead of Anduril.

Here is a manual for NarsilM:
