Overclock T-Mobile Galaxy S II To 1.8Ghz With Jugs Custom Kernel
Just when we think that the Galaxy S II has been pushed to its limit, we are proven wrong and the device shows no limits. Earlier we covered a news on the Galaxy S II being OC’d to 1.6 Ghz, and considering that we’re talking about a dual-core processor here, it was massive! Now, Team Kang of XDA-Developers has released a custom kernel that will push your device to an insane 1.8Ghz, but not the international version of the SGS II, but T-Mobiles Galaxy S II. How would you go about achieving this on your device? Simple just flash the custom kernel on your device if you’re rooted and have a custom recovery installed. We’ll show you how, as we take you through a step by step installation guide.
The kernel comes as two variants; one with a simple OC at 1.8Ghz and one Undervolted kernel giving you 1.8Ghz. The obvious and natural choice would be to go for the Undervolted kernel but people have reported performance issues with it, whereas the regular version seems to be working fine for most. Furthermore, it is also advisable to be coming from a stock rooted kernel. 
That said, let’s get this kernel up and running on your Galaxy S II and get some sweet overclocking done.
Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.
Requirements:
- Rooted T-Mobile Galaxy S II with ClockworkMod recovery installed. See our guide on rooting the Galaxy S II.
- (https://rbirg.com/kernel_test/kernel-jugs-0.1.zip) UV Kernel @ 1.8Ghz.
- (https://rbirg.com/kernel_test/kernel-jugs-0.1v.zip”) OC Kernel @ 1.8Ghz. (Recommended).
Instructions:
- To begin, download the kernel of your choice from the link above and copy it to the root of your SD card.
- Once done, reboot into recovery by pressing the Volume down, Home and Power buttons together, letting go of the power button when the boot screen appears.

- Now wipe cache and wipe dalvick cache.
- Select install zip from sdcard > choose zip from sdcard and select the kernel copied to yout SD card.
- Once the kernel is flashed, cross your fingers and reboot the device.
Once the phone boots up, it should be clocked to 1.8Ghz by default. Download SetCPU or CPU Master from the Market to change your clock frequencies or set profiles. For updates and queries, head over to the forum thread at XDA-Developers.
:O nevermind! it just took about 3 minutes to boot up
This broke my phone 🙁
EDIT: nevermind
