How to flash Leankernel for the Galaxy Nexus I9250
All great ROMs become even more awesome with the right kernel. Unfortunately, pre-cooked ROMs don’t always have the kernels with the modifications that you need. That is why some experienced users flash kernels to improve performance, speed, or battery life. However, if you want a kernel for your Samsung Galaxy Nexus GT-I9250 that is stable and fast, then the kernel known as Leankernel by XDA Developers member jackpham will work best for you.
The LeanKernel is one of the many well known kernels in the Nexus forums. Aside from its stable and up-to-date build, the developer has removed unnecessary kernel components and has overclocked it to 1.65 gigahertz to make the kernel run faster. RAMDisk has also been tweaked with custom SR tuning and SoundControl. This kernel is also compatible with all Jelly Bean releases. There is more to this lean kernel than what meets the eyes, so try this stable and fast kernel now.
