Overclock AT&T Galaxy S II Skyrocket To 1.83Ghz With Custom Kernel

183734-samsung-galaxy-s2-skyrocketEarlier we covered a post on overclocking the T-Mobile Samsung Galaxy S II to 1.8Ghz with the Jugs custom kernel. 1.8Ghz is a massive overclock especially if you consider the fact that you’re overclocking a dual core processor. If you own an AT&T Galaxy S II Skyrocket, you might have felt left out, but not anymore thanks to XDA-Developers forum member Da_G, who has recently released a custom kernel ported over from the Jugs0.3 kernel to the Galaxy S II Skyrocket. Yes, this means your Skyrocket can now hit the 1.8Ghz mark! To be precise the the overclock supports a max of 1.83Ghz @ 1.3v and even gives you UV support, init.d support, boot animation support, compiler optimizations and is an insecure kernel itself for ADB root access.

For those who wish for an overclock that is actually not reaching sky high, 3 more variations have been added at 1.67Ghz, 1.72Ghz and 1.78Ghz. Another variant at 1.83Ghz @ 1.325v has also been included.

Installing the kernel is a breeze and you wont have to do much. It has been packed in an easy to install zip package that is ClockworkMod recovery flashable. So let’s get on with some overclocking on the Skyrocket!

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.



  1. To begin, download the kernel of your choice from the link above.
  2. Place the kernel on the root of your SD card.
  3. Reboot into recovery and make a nandroid backup.
  4. Select wipe cache and wipe dalvick cache.
  5. Navigate to install zip from sdcard > choose zip from sdcard and select the kernel you copied to the SD card.
  6. Once the kernel is flashed, simply reboot your device.

    little worried, took me 3 boots to finally start after. but the 
     1.83Ghz @ 1.325v. is working now.

    how is that different than the  1.83Ghz one?

    • Bailez

      The 1.82 GHz runs at 1.3v while your version runs at 1.325v. For example my skyrocket was not stable at 1.3v so I went with the 1.325v kernel.

    how do you check for cpu status on skyrocket?  like to verify that it has overclocked to 1.8ghz

  • beastmode
