Pre Requisites:

  • Most importantly, you need to ensure that all the data is backed up with the below mentioned tips and not using the KIES. Just in case if the data gets lost or corrupted in the process of rooting then you can easily restore the same, all thanks to easy tips below.

Notes – Backup in the mail so that you can then restore manually,
SMS Messages – Use “SMS Backup & Restore app”,
Contacts Stored in Phone Memory – Sync with the Gmail application,
Call Log – Call Log and Restore Videos,
Images, Videos & Files etc.– Copy to internal / External SD Card,
Internet & MMS Settings – Backup all the settings from “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Ensure that you have ADMIN privileges in your computer so as To get the full USB read / write access. Close all the tools like Firewalls, Antivirus suites and also the PC Suites in your computer or else these tools will tend to interrupt the process of rooting.
  • Also, you need to ensure that the phone is left with the minimum of 50% battery charge so as to ensure that the phone doesn’t get turned Off in the middle of rooting process.

So, assuming that all the above instructions are followed you can now proceed to the procedure to Root Galaxy S2 on XWKL1 firmware.

    Iwant to ask why I need :

    “”In the recovery mode, select Wipe data/factory reset and also you need to select Wipe Cache partition and then reboot your device by selecting reboot system now option. If the device boots normally then again you need to try the same to enter into the recovery mode.””

    Why I need this after rooting?

    Thanks.

    Hi Pradeep,
    I have updated my Galaxy S II with this kernel i.e. XWKL1 but did not Root it and it shows the kernel version: 2.6.35.7-I9100XWKL1-CL809037

    You said this is a official kernel version, but when I connect my phone with Kies it says Kies can not update the current version

    Can you explain me why? When the Official ICS 4 becomes available in March, can I update my phone through Kies ?

    Hi Pradeep.
    I have been following this site for some time and have been benefited a lot.
    Thank you for all your had work.
    I am planning to Root my Galaxy S2 which is 4 months old, but I have some question and I’d be very thankfull for the answers.

    1) Rooting will void the warrenty, Yes. But how can I get back the warranty if I want to claim for it?
    2) Is it necessary to flash another kernal or will it be okay if I stick with the present one? (Bulid version is I9100DDKL1)
    3) In case the phone bricks, can you please inform how to unbrick it if possible?
    Awaiting your reply.
    Thank you in advance.

    • Pradeep Neela

      February 13, 2012 at 5:34 pm

      you can claim back by applying the stock firmware again!
      you can update on your current kernel

    Dear Neela,
    What is the basic purpose of rooting the phone?

    • Pradeep Neela

      February 12, 2012 at 12:12 pm

      once you root your phone, third party developer tools can modify your system files to customize the phone!

      It wont be gone as you have rooted your phone and there is nothing to worry about it. It should be done in the next firmware update.

    Steps to remove the Yellow Triangle

    1) Get a Samsung signed stock kernel (you can get it from XDA developers forum or samfirmware.com)
    2) Flash the Samsung kernel thru Odin, the device will boot and you will still find the CWM with limited function.
    3) Extract the CF root file until you get the zImage file. save the zImage file in the Ext/Int SD card
    4) Now open the CWM manager and select the Flash Kernel option and select the zImage file, device will boot and you will now notice you no longer have the warning triangle during boot.
