Kernel is the heart of the Linux operation system like Android. The better kernel you have, the better performance you will get for you Android phone like Samsung Galaxy S II. So what is the benefit of using custom kernel? Most of the custom kernel will give you root access permission just like CF-Root. BusyBox and Superuser should be added too. Besides, ClockworkMod Recovery is also another must have component. In addition, depends on which custom kernel that you install, some have boot animation support, overclocking, undervolting voltage control, multiple tweaked governors, GPU overclocking, I/O tweaks, automatic backup of EFS partition, BLN support and more…

    What the best custom kernel that u may recommend?

      Yes, you can change kernel. But not all kernel will work well on the firmware that you use.
      Personally, I use CF-Root kernel only which nearest to stock kernel.

    Hi Jayce, I liked your guides so far,
    Can you please tell me how do I know to mach up a kernel with a ROM ?
    Does a custom ROM like CM7 has its own kernel ?

    • http://www.jayceooi.com Jayce

      mach up? Sorry, don’t understand.
      Yes and no. Depend on the ROM chef.

      • ehknaton

        For example using Siyah kernel with Cyanogenmod ROM. I read that’s a good mix ?

        • http://www.jayceooi.com Jayce

          No idea because I did not try it personally. Try it yourself to find out. :)

    Hi Jayce,
    I’m using SGS2, and i already upgrade my ics kernel from official samsung DXLP7 to SiyahKernel 4.1.5 , but after that my SGS2 not smoth, if i touched the icon, the respon very slow and after that usually hang and the SGS2 restart automatically. Sometimes SGS2 hang and i must release the battery.
    I still use ROM DXLP7 (official samsung).
    Before flashing my kernel, i did Wipe chace and Wipe Dalvik chace via CWM. Should i Wipe data/factory reset too?
    And what should i do for my SGS2 for the best performance??
    Can you show me step by step?

    • http://www.jayceooi.com Jayce

      You can try that. Maybe SiyahKernel is not suitable for DXLP7 firmware.
