[How To] Root Samsung Galaxy S II I9100

Technology 11 Comments

Here’s a root procedure for SGS2 phones. Some people try to root it with Gingerbreak. But Gingerbreak is not a perfect tool for rooting this device as some users complained about this tool not rooting their devices. No doubt, Gingerbreak rooted some of the SGS2 phones but it doesn’t work on all the retail smart phones. So, we are here with some other methods for you.

Chainfire, senior moderator at xda is able to successfully root the Samsung Galaxy S II (I9100) smart phones.

Before following the below listed steps, first please note the original kernel version by navigating to Settings –> About

In the tutorial guides, if you want any of the files in email from us, please comment at the end with the files needed. We would be happy to email you.

    Hello, i don’t want to cheese anybody off with repeat questions etc, and i apologise if i do/have.

    I own a Samsung Galaxy S which is unlocked and updates as it should with Kies.
    Last week, i bought a Samsung Galaxy S2, which was locked to the T-Mobile network.
    The lad at the shop where i bought the handset from, unlocked it(i am on the 3UK network, and have NO intention of changing), and rooted it.

    The issue that i’ve got with the handset, is the mobile hotspot feature. I tether my laptop to my Galaxy S and use the internet with no problem, but not so with the Galaxy S2. I can tether it to my laptop, but that’s it. Everything else seems to work ok. Oh, and i have the yellow triangle each time i switch it on.

    I have been reading various posts on different sites about rooting and i’m confused as ever – I had an accident with my n900 and had to wait for 2 months when it was sent to a Nokia High Level repair center, i p/ex’d it for the Galaxy S2.

    The Galaxy S2 information is:

    Model number GT-I9100
    Android version 2.3.4
    Baseband version I9100XXKG1
    Kernel version 2.6.35.7-I9100XWKDD-CL161513
    root@DELL103#2
    Build number GINGERBREAD.XXKG1

    I have read that i need a “a stock kernel” to get rid of the warning triangle, i have seen on the XDA site different 3UK kernels, i haven’t got a clue which one to choose. Also, the latest version of Odin and SuperOneClick??? Does the app ‘Superuser’ come with rooting? as it’s in my menu.
    Is the firmware and everything else i need downloaded with Odin? What do i do in regards to installing future firmware updates?

    Basically – i need an “IDIOT PROOF”, step by step guide to flashing/rooting/updating my Galaxy S2, so it’s bug free and works as well or better than my Galaxy S. I haven’t tried anything yet as i don’t know which bit to do first, and i’m very wary of the Galaxy S2 ending up like my n900.

    Many thanks, Mick

  9. Sean says:

    Hi there,

    Can you email me an insecure kernel for BOKG1 or BOKG2 please?

    I found a BOKG2 insecure kernel but when I extracted the zip file it wasn’t a tar file but an image file. A bit disappointed.

    Your help would be greatly appreciated.
    Thank
