[Xiaomi Redmi 2 ROMs, Kernels, Recoveries, & Other ] Kunagi:
I just flashed it, I will try to force the error (being on battery without any logcat with bluetooth+wifi enabled and playing music with aimp).

Nice new logo animation!

And fast charge now works! In the past it showed always "1500mAh Charging" and now it shows "2000mAh Charging rapidly".

Also this version runs even smoother than the previous one.

I've seen there's no zRAM enabled on this version.
