Overclock Samsung Galaxy Y to 1.2Ghz

Here is something special for all of you!  Here is something which could overclock your galaxy y from 832 MHz to 1.2 GHz. This overclocking is made possible by one the xda-developer “Maroc-OS” which his Kernel Merruk 2.5.

Maroc-OS, had removed the original download links to this kernel because more than 80% users reported that the kernel didn’t work (never boots up!). But it’s really great that one other developer “BiswajitBarman” find a way to install it. So try it yourself!

Keep in mind, This is not an officially released version and has bugs in it. So be carefull. Check the comments for bugs reported by others. Also remember to have a backup with cmw.

Things to download

  • ClockWorkMode : Download this if its not pre-installed. : Download
  •  Merruk technology2.0.tar  : Download
  •  Elite : Download
  • : Download
  •  Kernel : Download

How to? 

  • Copy all files to Sd-Card [be sure it is not in any folders].
  • Extract the “boot.img” file from Merruk technology 2.0.tar into the sd-card.
  • If you have the app “Link2Sd” installed, do a clean up sd-card. If you haven’t installed it, continue to step 4.
  • Go to phone’s recovery mode by switching off phone, press “Vol up + Home + Power”.
  • Flash if you haven’t pre-installed it [vol up/down for choosing options & home button for selection].
  • Now you are in Clockworkmod, Now choose “Install .zip from Sd-card” and flash “kernel”.
  • Go to Backup & Restore and backup your rom.
  • Now Flash
  • Next, Go to Advanced and do a Error Report.
  • Flash
  • Go to Back and restore > Advanced, Restore “System, data & cache”. Keep in mind not to restore boot and sd-ext.
  • Done! Reboot and enjoy.

First boot make take sometime. If it is not booted even after 10min, do the steps again and in step 3 clean up sd-card with link2sd.

For Stock Rom

Thanks to “Jeff” for this method.

3.Check if your kernel changed in settings> about phone> kernel=

    Hi, i do what you say. and have still problem but not same problem. now is ok starting mobile but after lagged mobile in black screen only black 😦 you know how can i fix ? can i have overclock to 1.2 ?

    • admin says :

      Okay do one thing. Flash a new firmware with odin. [Don’t forget to use the .pit file in odin and enable repartition.]. After that try to flash a new Rom (like Jellyblast or Hyperion) which usually have a custom kernel in it. Then flash any of the merruks kernel like merruk 2.0.

      Then try to do these steps…

  2. paklic9 says :

    ok i dont need do one think. I yesterday do again from tutorial:
    and now work have overclocked to 1.248 ghz.
    But have still lags in game. Game name is subway Surfers. say why?? 😦

  7. paklic9 says :

    hi, what is better for games. overclock my galaxy y to 900 mhz or 1 ghz or 1.2 ghz(but at 1.2 ghz only 250 ram)??? Please help me.what is better for games.

    And wha is the best rom for playing games?

    • admin says :

      1ghz is a laggy one and 1.2ghz is not at all stable. I think 900mhz is quite stable. well, I don’t used to play games on my phone and so I don’t know which one is the best. may be you can use “kuro” kernel.

      Rom, you could use any custom Roms like hyperion etc..

      • paklic9 says :

        I now have 900 mhz and i think it is the best maybe but i dont know. And have STOCK rom. And have kernel version: root@ubuntu 39.
        Ok i will use 900 mhz.
        What rom is better Hyperion rom or Techdous Rom?

      • admin says :

        Techdous is for Galaxy Y duos right? Hyperion will be my choice.

  22. paresh kothari says :

    Hey dude can this works on galaxy pop GT S5570?????????
    Plz rpy

  23. Vaibhav says :

    Hello Admin,
    I have installed JellyBlast v3 with Updated latest OTA5 Pre-Nemsis..
    what should i do? i also tried to install it .. it starts and suddnly screen stops working or sometimes Blackscreen or restart for longer time.. so i managed to recover from it, flashed back to stock and installed JellyBlast v3 again with all OTA updates Pre-Nemsis.
    Please help!!

  24. Angel says :

    hello my samsung y is new i want to install first the hyperion then do the overlock does it matter what i do first? or wich should i do first please help..

    • admin says :

      you don’t have to install hyperion for this overclocking. read my post and you’ll find how to install the kernel.

      But your galaxy y is new right? So before overclocking, flash any other kernel like merruk 2.0 first.

    • Vaibhav says :

      Angel, My suggestions is that not to install ANY Custom roms… Murruk kernal Works fine on Stock Roms..
      But to install Murruk Kernel on stock rom requires Kuroz Kernal..
      So first Flash “Kuroz” latest kernal than Flash “Murruk 2.0” do not directly flash Mukkrk 2.5.

  25. Rom says :

  29. Sipun says :

    Hey dude i have the same problem.
    My sgy also stucked at sgy logo.
    I’m flashing a stock rom but it says fail why plz tell me?

  30. Alar Antohin says :

    I added you to Facebook. I got some questions about this thing
    1. Does it work with Creeds ROM 5.5?
    2. Does it touch my installed apps? I mean do I have to re-install some/all of them?
    3. Does it touch any system settings, do I have to re-set some or all of them?
    4. There is possibility phucking something up. After phucking up, how to restore?

    If it works with my rom and stuff then it’s good. Currently I use V8 Supercharger scripts, they made my phone super fast. If you are not using them. I completely reccomend using them after that overclock thing. It will make it very fast as it optimizes memory usage n other shiet
