Galaxy S2, Cyanogenmod and Fluxi Kernel

By | July 2, 2012

In my previous post I listed my settings for SiyahKernel and I’ve since swapped to Fluxi kernel (XDA thread) and figured I would write a new post. I’ve not been running it long enough for any “real world” tests, but it seems to be running quite alright.

Edit: I’ve since swapped back to SiyahKernel as it seemed to be a bit more stable (with -75mV) and I didn’t have time to get a stable undervolt on Fluxi. It just all-round felt smoother.

Note: If you decide to do anything like this to your Galaxy S2 and it breaks, I will not be held responsible. ;-)
