The Samsung Galaxy Note N7000 has received significant attention in the ROM development department. CyanogenMod, AOKP, AOSP, ParanoidAndroid and of course TouchWiz-based ROMs have all made an appearance. The trouble with all these ROM variants on the N7000 is that TouchWiz-based kernels cannot be used on CyanogenMod ROMs and vice-versa. Naturally, this limits the choice of kernel depending on your choice of ROM.
XDA Recognized Contributor g.lewarne has broken through this barrier and developed a custom kernel that is compatible with both Touchwiz and CyanogenMod based ROMs. HydraCore Universal kernel comes in both a stock frequency/voltage version, and an overclocked / undervolted version for those who prefer to tinker a little more. It also contains all the usual kernel tweaks such as additional governors, I/O and scheduler tweaks, memory optimizations, and much more.
If you’re sick of swapping kernels between TouchWiz and CyanogenMod based ROMs, or just want to try out another tweaked kernel, head on over to the HydraCore thread.
