If you want to experience the “true” power of your Galaxy Note 2, you will definitely have to overclock to 1.8Ghz (from stock 1.6Ghz) and also see how much you can tweak/undervolt your Note 2 to maximize its performance and battery life.

For that, I do highly suggest Perseus kernel, available for most Note 2 variants including AT&T SGH-i317, T-Mobile SGH-T889, Sprint SPH-L900, Verizon SCH-i605, international GT-N7100, and GT-N7105. For Canadian users, you can use AT&T or T-Mobile versions, just match up the first 7 letters of your model number.

Perseus kernel was the Note 2’s very first custom kernel (I still remember) on the first week that Note 2 was released to the public. When I first tried Perseus kernel, it kept freezing up on me and was not stable at all, but after almost 6 months, I am glad to say Perseus kernel is one of the best kernels for the Note 2 that I’ve tried.

To install Perseus kernel, you will need to be running either stock or TouchWiz-based ROM on Android 4.1.1 or 4.1.2. Also many custom ROMs do offer Perseus kernel as default or come as an option in AROMA installer. However you install it, once you are running Perseus kernel, you will be able to easily overclock to 1.8Ghz and make your phone at near maximum speed.

Once Perseus kernel is installed, you will find an extra app in your app drawer called “STweaks” app.

And boy, you can certainly feel the power of overclocking on the Note 2, especially you are already starting out with 1.6Ghz stock, at 1.8Ghz, you get additional 200Mhz on ALL FOUR CORES, a huge difference when comparing to a dual-core slower phone.

For the average user, I do recommend overclocking to 1.7 or 1.8Ghz and if you play a lot of HD games, you can also overclock GPU to 733Mhz. Make sure you don’t set “Set On Boot” until you find a stable frequency for your Note 2 as every phone may be slightly different from others.

With undervolting, theoretically it’s possible to get much better battery life even with overclocking. This might take awhile to do so make sure you have at least 2-3 hours to test when you are tweaking voltages. Find the lowest voltage you can go on your phone for each frequency step until you find bottom, when your phone reboots/freezes. Once you find that bottom point, try choosing a voltage slightly higher to be safe. After find some good undervolting voltages, test out your phone’s battery for the next day or two and don’t forget to report back at so others can also learn from you.

There’s also more tweaks you can do with audio for your speakers and headphones, I will leave that up to your bass heads out there.

Try it out, see how much you can overclock and do post your Quadrant and Antutu scores!

Before installing, just in case you want to revert back to your current kernel, make a backup ROM in your custom Recovery using CWM or TWRP. Backing up your ROM also backs up your kernel.

To install, reboot into recovery, install kernel, and reboot!

    I cannot get this to work. Never had a problem with any of your videos. I saved the zipped kernel to my SD card and rebooted into TWRP. I am running Macks Rom 3.2 on Android 4.1.2 and when I try to install I get an error Fail message. Using the Sprint version. Help!

  2. Scott says:

    It was just a failed download message. I ended up having to download the file from another website. The download must have been corrupt because the other file worked fine. Keep up the good work.

  3. eric says:

    this does not download as a zip file. Cant install it

    Running on verizon JediX12 will not give data, I can still send/recieve texts and phone calls. Help

  7. Anwar says:

    It does not download completely. it is only downloadable only 97% afterwards it still. so please refresh the download the link for future use.

  8. Enrique Huerta says:

    OK can this be installed with mobile Odin? I am Rooted with stock recovery so I cannot flash kernels, only with mobile odin! At least that’s what it say’s on XDA!

  9. Christian Adams says:

    Hey Max! Are there any other kernels besides the Perseus kernel? I know Jedi comes with the Saber kernel. I’m running CleanRom 2.0 with the Perseus kernel now. Just curious. BOOMSHAKALAKA

    • Max Lee says:

      Jedi kernels are very nice too, there’s couple more kernels, if you want to try them out, look on XDA.

  10. Lee Rose says:

    Does this kernel and version of stweeks have the same capability as the redpill kernel (not made for the verizon version of the note2 🙁 ) allowing you to swap your internal memory for you sd memory?

  11. Matt Durrant says:

    I have this on my Note 2 N7100 with stock rom 4.1.2 rooted. Flashed with mobile odin without any issues

  12. Nico says:

    Goodpm. Your rom is stock? Did it work fine? Did you back up your stock kernel? What is mobile odin? Sorry just a noob for this.

  13. Nico says:

    Will this work on non rooted stock roms?

  15. J says:

    Downloaded the i317 version and got stuck at the Samsung boot screen. Redownloaded and tried again with the same result. I then grabbed it from xda,which has version 36 btw, and it worked flawlessly.

  16. Taher Lilywala says:

    Can I flash a custom rom after installing this kernel if I want and will the kernel be automatically replaced

  17. Taher Lilywala says:

    No because installing a custom kernel or a custom rom requires root access

  18. Mohammed says:

    im using criskelo custom rom on my galaxy note 2 with perseus kernal install. it works nice, well yes tweaking may need some time to find suitable balance for your phone. as u all know once everclocked & gpu clock on your phone processor will perform very fast which produce heat at back of your phone. my question is that are there any suitable tweaks beside standard/default tweak that can reduce heat to the phone as i dont take risk to touch on voltage part on the stwaek app. please feedback as i need to know your ideas.

  19. Coletrain says:

    Is there another kernel? I like underclocking and SetCPU does not work with this?

    • Coletrain says:

      Well the Sabre kernel I found only showed ” Samsung Galaxy Note ii” and them a blank screen. Battery pull.. I restored. I find xda hard to navigate. Do another kernel review, please. For sprint. I’mgoing to try llab rats now…. But I’m still searching for another kernel. Thanks again, watched most all your video.

      • Foyz says:

        h i just installed Perseus Kernel because i wanted to use STweaks. After i installed it and rebooted I would get the “GalaxyNoteIIGTN7100” screen for literally a second and then go on to a blank black screen (near enough the screen looks as if it is turned off). I just want to speed up my phone. Is there any other app that can do this for me instead of STweaks?

  39. dziarsky says:

    What happen when i have already flashed perseus kernel on my 4.1.2 firmware and Samsung release new 4.3 soft? There will be some: errors / turn back to regular kernel / just rom update with perseus on board?

    I am just wondering how its works – kernel is changing with android versions? Perseus from this article fits only to my 4.1.2 ?

    Thanks for answers.

  40. Papapau says:

    Undervolting, “theoretically” should increase battery life…. But for me, it doesn’t.

    200Mhz – 1.3GHz
    CPU gov:
    CPU volt settings
    1.3 – 1000mV
    1.2 – 1000mV
    1.1 – 1000mV
    1.0 – 1000mV
    0.9 – 1000mV
    0.8 – 1000mV
    0.7 – 988mV
    0.6 – 938mV
    0.5 – 900mV
    0.4 – 850mV
    0.3 – 813mV
    0.2 – 725mV

    Don’t get this the wrong way completely, my phone is underclocked and undervolted but that setup is still snappy and very unnoticeable lags if none. It’s just I’m setting this up this way to achieve a better battery life, but it doesn’t do..

    I use Batery Drain Analyzer 3.4.2 (paid) in checking the drain amount per percent of the battery. again, didn’t change a thing compared to pre cpu undervolts..

    anyone can attest to an opposite conclusion as mine?

    Can u suggest any kernel for AOSP roms because i was thinking of flashing the perseus kernel before i saw the warning. Please reply cause i am eager to overclock my gt n7100

  46. Jim says:

    Downloaded Perseus at about Noon today and have been playing with it ever since. I just have the stock ROM rooted but have uninstalled a lot of the crapware on my N7100 like Yahoo Financial, etc.
    Works great, and the first thing that I did was to go into the volume settings because of that nagging problem that some Note 2’s have with incall volume. Still haven’t brought it up all the way but it seems to be working… and I’ve tried ALL of the useless stuff off of the Play store trying to bring up the volume!
    I’ll probably be playing with the STweaks settings for the next few hours until I go crosseyed. Haha.
    Thanks, Max for the review. I just saw it over the weekend and decided to try it.

  47. This is a topic which is close to my heart… Best wishes!
    Where are your contact details though?

  48. Dylan says:

    Hi, I am currently using a Galaxy Note 2 T889 with CyanogenMod 10.1.3 on it. I was wondering if there are other kernels that I can use with this combination besides the stock kernel, that could overclock my phone to at least 1800 Mhz and maybe GPU overclocking too?

    Is there a custom kernel for sprint note 2 running cm11 , for over clocking

  57. Foyz says:

    Hi Max.
    I want persues kernel on my phone. Do i just install it like i uninstalled any other rom. I already have Somtax rom installed (which is like Tiagra) and i have now android 4.3. I don’t want to have to remove one rom for another. Or is persues kernel just a tweak. I just want to install STweaks, that is all so, i can over clock my note 2 because i want it to be a little but faster. Can anyone tell me how to install perseus Kernel without losing my android 4.3 Somtax rom. is it as easy as going into CWM Recovery and installing from there? If so do i need to wipe cache or partition etc or do i just install straight from extsdcard/sdcard? I just want clarifcation on what to do and how to do it right.

  58. David Kwok says:

    How do I know if I have TOUCHWIZ ROM? I rooted my N-7100 (4.3 firmware) yesterday. Thank you.

    • Foyz says:

      Settings option ->
      Applications manager option ->
      “All” tab ->
      “TouchWiz Home/Easy”
      …version is then shown just below the title.

      The fact that this app is here would obviously show you are running it.
      If it’s not there then you are probably not running TouchWiz..

      In the future don’t comment on this site. It’s a ghost down. Go to XDA forums in the future.

  59. Columbus says:

    The best questions never get answered. It’s ironic how the one valid question “does this kernel supports internal memory swap” never got answered here. Or maybe you guys are too noob to even know what that question actually means ?

  60. Alex says:

    Please help me, after i flashed other kernel my device can’t boot. It doesnt even load the bootanimation. im still able to go in recovery and downloadmode. Maybe somebody can give ma a link to the stockkernel?

    • JIM says:

      Alex..same thing happened to me with my N7100 rooted stock ROM. Couldn’t find a solution so I just reloaded the stock ROM (4.3) from KIES and started all over again with the re-root process. Took me hours, but it’s the last time that I ever try to use a kernel without it being specifically for the device/ROM combination. I’m currently on the stock kernel. I had Perseus on 4.2 and liked it so I thought that I’d try it on 4.3 but it was a definite no go.
      The KIES solution was just murder. I could get into download mode but not even into recovery. It took me 11 tries with KIES to finally get 4.3 installed, but it finally did take, but I’m still on “1” on the binary cout using Triangle Away but at least my phone works now.
      Next time, be very wary… as I’m sure you’ve learned.
      From now on, contact the dev and if they don’t answer, it’s probably because they haven’t tried out the device / ROM combination.
      Good Luck!

      • Alex says:

        Thanks, i saved my phone, by flashing the stock rom with odin. I dont understand why but after rebooted i still had all my datas, which makes no sense for me, because i wiped it a couple of times.
        U will try to ask the developer, maybe he can help me flashing the kernel.
