How to update Samsung Galaxy S2 GT I9100 to Gingerbread XXKG1 2.3.4 Firmware

Procedure to Update Galaxy S 2 GT I9100 with Gingerbread XXKG1 2.3.4:

  • Download the Gingerbread 2.3.4 XXKG1 Zip file in your computer after which you need to unzip the same to the desktop. In the process of unzipping please note that you will be asked to enter the password, enter the password as androidadvices.com.

Enter Password XXKG1

  • Once you unzip the zip file you will see that in all there will be 5 files which are the Odin 1.83 version, Code file, CSC File, modem file and also last but not the least the PIT file too which we will be using them in the due course of this article. After unzipping the files you will see all the files as shown in the below screen shot. Just in case if any file is missing then you will have to download the same again.

I9100 XXKGI Files Extracted

  • After this, just open the “Odin Multi uploader” file from the extracted folder and then you will have to now turn the phone Off as you will have to turn your phone ON in the download mode as shown in a short video below for your convenience,

Odin 3 v 1.81

  • Now, as soon as you get into the download mode, you will have to connect the Galaxy S2 GT I9100 to the computer with the help of USB cable while Odin opened in the desktop. As soon as you connect the phone, you will see that first ID:COM box as shown below will turn yellow and in the message box you will see that it will show ADDED as shown in the below snapshot and after that you will have to add the files respectively as shown in the next page,

    hey Neal,
    looking at your blog,i can say u r doing a very good job:).
    okay, heres my problem. i bought a galaxy s2 recently. It has this feature which opens up vlingo voice control if u double tap the home button.But on my phone, somtimes this voice control opens if i single tap the home button. I took it to the samsung service center n they upgraded the firmware to KE4/KI4(i am not sure which one cuz am not aware of firmwares) and the problem still existed.Then i got the set replaced.The bad part is, evn this phone has the same problem:(. Is this an issue concerning vlingo or samsung? or does it have to do somthing with the hardware? should i downgrade the firmware cuz my friends’ galaxy s2 phones work just fine with android version 2.3.3. my phone details are here:
    android version: 2.3.4
    baseband version:I1900GDDKH3
    kernel version:2.6.35.7 root@DELL156 #2
    build number:GINGERBREAD.XWKH8
    please help me find a solution to this problem which doesnt involve rooting my phone

        Is there an official PIT file for my CSC code XSP?

        Thanks

    Hi I just did the update being discussed in this thread. May I know what to do if I happen to decide to get back to original stock condition of my phone specially concerning the restoration of the official stock PIT file.

    I’ve done several updates via Odin but with no modification to the PIT file but when I install the PIT file from this update in this thread, my phone became very unstable and restarts and lags the menu swiping like very slow even if I revert back to my previous firmwares which is fast before. Im looking forward to your response with this matter. Thanks

    I have a Galaxy S2 GT-I9100

    Hi Neal,

    I’m getting a SGS2 phone, got 2 questions, any insights appreciated:

    1. I am looking at 2 versions of the phone: one made for Europe – sticker under battery says ‘Made by Samsung’, no date, battery made in Korea; and the other is for South America – sticker says ‘Korean product 07/11′, the box says ‘Made in China’, battery made in Japan. In your experience, are there any diffs in terms of hardware quality between two versions labeled like these?

    2. Firmware of the South American model does not support European languages that I need. Is there an easy way to add new languages?

    Many thanks!

          hi. i tried installing on an updated windows 7 and it worked. but I did something wrong. sorry for my stupidity, i’m a noob on android and the sg2 is my first android phone so please please please bear with me. I know I should have read instructions but I didn’t know that I can’t use another pit file. I accidentally used sg1 pit file. :( odin got stock on the don’t turn off target and I’ve read on another website that you can just disconnect and remove battery. I did. and when I tried to turn it on, it won’t. You think samsung can still fix it? My phone is locked with my carrier but my friend told me to just take it straight to samsung service center. When I insert the battery and try to turn it on for some minutes, the back part of the unit will get warm, on the camera part. you think there’s still hope?

For other connections I have to put my phone in roaming mode in order to have a connection (wcdma). Furthermore I have lost videos and photos (they don’t show up in the gallery), and as you asked there is no gps signal what so ever. Wifi works.
    Can I go back to 2.3.3 (or is that not necessary)

        thank you for your reply Neal, i want to let you know that this is how i bought the set itself. i have not flashed any new firmware or rooted. I think the shops put custom rom becuase there are some chinese bloatware in my set and i cannot rid of them even after doing factory reset. Would it be safe to upgrade to the new leaked firmware you mentioned without damaging my phone or losing functionality here in china?

        I cannot pinpoint what exactly the ppl did here because the firmware, baseband and csc are same to many of that outside china.. Only thing i dont understand is my kernel is: Kernel:2.6.35.7-I9100XWKE7-CL215725root@DELL103#2

While I can revert back to stock and it will work, every time I put XXKG1 on it again I don’t get internet service (I get bars of service, just no H or 3G next to it). With that said, I was wondering if you know any way to possibly fix it or work around it. Thanks.

    No problem downloading apps from market like one other user.
