How do you edit the slothy.txt? For some reason I couldn't edit it, but I could overwrite it, which is basically the same thing, I know.
Anyway, for some reason, all 4 cores seem to be on all the time, and at max frequency too! Is that normal? I don't want to blow up my phone; that happened to me once.
EDIT: They're mostly always at max frequency, but scale down sometimes.
I'm currently running gru's lollipop build so I'm not much help. I never edited the slothy.txt file. I'm a believer in leaving things mostly how the dev makes them so I don't break something.
As for the four cores, did you change something in slothy.txt or with Trickster mod? I don't think both of them play nicely together.
