So, before you proceed to root your phone, be informed that it’s very important that you need to be on the XWKK5 2.3.6 version of firmware before you proceed. To know on what version of firmware you are currently on then you need to go to path “Settings > About Phone > Firmware Version” where you will find the version of Android OS where it will show Gingerbread XWKK5 2.3.6 version. If there is any other version then first up you need to apply the update from the below mentioned link.

Procedure to Update Galaxy S2 with XWKK5 Gingerbread 2.3.6 Firmware

  • So, after this you need to follow the list of detailed Pre Requisites so as to facilitate the smoother and safer rooting process which will also take care of the data or else chances are that you may lost the data.
  • Just in case if you are new to rooting then we would like to tell you that rooting will void the warranty and then only way you can reclaim the warranty is by applying the update of XWKK5 Gingerbread 2.3.6 firmware in your phone. There are many benefits of rooting out of the most important one is that you can easily apply the custom ROMs as told earlier. Apart from that, rooting also allows you to remove the system applications which come per-loaded in the phone. Apart from that you can also install the applications which require the root access. The only disadvantage is that once the device is rooted, the warranty gets void.

Important: Disable the tools like Voodoo lag fixes if any applied from the recovery mode or else it will brick your phone. The recovery mode can be entered by pressing  Volume Down Key + OK button, and holding both simultaneously press the Power Button. You need to get into the Advanced mode to disable any sorts of Lag fixes are there. Refer below video to enter into recovery mode.

    Hi Neal,
    Problem the phone is already 3e recovery .and to be able to install Custom Roms it needs to be 2e recovery. 3e recovery wont allow roms that are not signed to be installed. Do you know of any way to get back to 2e recovery with this firmware. I prefer 2.3.6 firmware as it is giving fantastic battery life.

      ONLY AFTER ROOTING AND INSTALLING THE CWM, YOU CAN ACCESS THE 3E RECOVERY!

    Hi Neal,

    I upgraded from v 2.3.3 to 2.3.6, when I had issue of the handset gping in circle during reboot. After this reinstalled v 2.3.4 & rooted the phone all done cleanly. After this I tried again upgrade to v 2.3.6 which happened like clockwork. Also I rooted the S2 which again went smooth. I used Odin3 v1.85 in both the above instances.

    The handset works fine.

    Thanks,

    You can get rid off the yellow triangle by extracting the zImage file from the original .tar file and then zip it with 7-zip. Upload the zImage.zip file to your SD card and then use CMW to it “flash a kernel”.

    My previous posting got deleted somehow!

    Just after flash, at reboot, it halted and there was “picture.jpeg” loading failure shown on the screen.
    When I connect to power, it reads “power jpeg” loading failure.
    I can still get the phone to get into the download mode, but as my phone doesn’t get recognized by any PCs for some bizarre reason, I am stuck now.
    I flashed my phone using mobile odin (I have used that before too, with no problems).
    I wonder if the firmware (downloaded through the link from your website) was faulty/corrupt.
    Anyway where do I go from here now.
    I would have probably easily fixed using the desktop odin, if my device were to be recognised by my pc.
    BTW, the PC has kies/latest samsung usb drivers installed on winXP and also Win 7 PC.

      To remove the Triangle

      Flash CF-mod
      Flash with Stock Kernel from XDA

      This will not affect the root but will get rid of the triangle

      Try to download the Kernel_I9100XXKI3 and install with the same procedure that you have done… I try this and it will working fine. You can ask Mr. Neal whey you can download that files.

          i have the above mentioned kernels. can i use either of them to get rid of the yellow triangle? will this affect my new version? will this affect my root? what is the difference between the two kernels? also i have two odin versions: odin3 v1.83 and odin3 v1.81… which one should i use? when flashing via odin, in which section should i select either kernels… pit, bootloader, pda, phone or csc?
