  8. Hello Neal,

    I have one inquiry in here regarding the samsung galaxy s2,
    I need to know how to use as a modem, connect it to my laptop, and then connect to the internet through my laptop, using my mobile operator data network


  9. I having Samsung Galaxy S2 from India. Here is the current versions on the phone, I am really confused on which files I need to download.

    Can someone help me with this.

    Current Versions

    Android Version : 2.3.3
    Base Band Version : I9100DDKE4
    Kernel Version :
    Build Number : GINGERBREAD.XWKF3

  11. hello NeaL,

    did you find any chinese version for me? i didn’t find, i am not so god in this but i hope you can help me.

  12. hi, my question is with regard to updating my android ginger bread officially. i have a samsung galaxy s2 which is still on 2.3.3 but obviously 2.3.4 is out. i want to know if there is anyway i can just update this via kies itself rather than go through this procedure, which no doubt seems simple but i was just wondering why kies hasn’t officially pushed it like when i plug my phone in.
    my second question is whether you have heard anything about samsung galaxy s2 getting the ice cream sandwich upgrade and when do you think that might happen if it does?

    • as of now Samsung hasn’t pushed update via kies to some countries, you can either wait or can apply update by Odin manually.
      yes, s2 will get ICS, there is no exact date for the same but as in when it comes, we will cover the same!

  13. and where i find this chineese version?
    also my phone still show SOFTWARE UPDATE FAIL and i can’t stop or do nothing whit him.
    please help me to fix my problem.
    NOTE: i’m still in china and i don’t have access to all sites to download files

    kind regards

  20. Hi Neal,

    I bought an unlocked Samsung Galaxy S II smartphone from in New York, USA. Prior to purchase, I explained to the employee that I am a tourist, living in Austria, Europe, and wanted to take the phone there upon conclusion of my stay in the US, and back in the hotel, I realized:

    The Samsung Galaxy S II sold to me is a Spanish version. I expected to get the international version (or at least the english version) of the phone, which supports many languages, including English and German, according to this link:

    The Spanish version I received has an English language option, yes, but apart from that, only comes with 3 more languages: Portuguese, Spanish, and Korean.

    2) In the box, there was no guarantee card. The box only contained the phone, 2 quick-start-guide booklets (one in English, one in Spanish), the US-power plug, the battery, the USB-cable, and additional earbuds. I double-checked thoroughly and did not find the guarantee card (2 year Samsung warranty) among the box contents.

    My questions are:

    - How can I download the German language pack?

    - Does Samsung do warranty repairs without asking for the warranty card? I hate the store receipt, and multiple times, I have read on their website that only the store receipt is required, can you shed some light about this?

    I mean the third party applications i have installed on my device.

    I want to update without re installing them again. how can this be done.

    I didn’t read in your instructions a way to back up application!

  24. Aslo please adivse on installing the Arabic Language bearing in mind that ill go for the Exynos Extreme Custom Rom

  25. Hi Neal.

    I want to update to this version but definitely without losing the installed apps and not losing the performance upgrade due to no clearing the cache” as i understood from previous comments, clearing the cache clears the installed apps, so if i don’t clear the cache i will keep the apps”. and I wonder if there is a way to back up and restore apps.

    Of course i am doing this only to install the Exynos Extreme Custom Rom

  30. Hi Neal,

    I want to downgrade the modem from XXKG6 to XXKG5, it appears that XXKG6 modems is problematic when comes to use Wi-Fi or 3G, and I want to know if I can remain on the same XXKG6 Firmware and with the modem from XXKG5 on my Galaxy S2. The problem is that now the battery drains much much faster when the Wi-Fi or 3G is on, compared with XXKG2. (before upgrading to XXKG6 I was on XXKG2). And if I can, the phone data will remain untouched? and my phone is already rooted. Thanks

  41. Hey NeaL,
    Mine is
    Model Number : GT- I9100
    Android Version : 2.3.3
    Baseband Version : I9100DDKE2
    Kernel Version :
    Build Number : GINGERBREAD.XWKE8

    Should i update my firmware right now or wait for the official update ?
    Is it safe ?

  42. Hi Pradeep :

    I recently bought the SGS2 from the middle east. I had an update waiting straight away in samsung apps. I updated, after which my battery life has decreased very much. these are my SGS2 specs using *#1234#
    PDA: I9100XWKF3
    PHONE: I9100XXKF1
    CSC: I9100JVKF3

    1) Can i update my phone with the XXKG6 2.3.4 without losing my warranty?
    2) Will the phone re-boot with another language other than english after the update ?
    3) As i am new to samsung and android, i do not know why we have to root our phone ? What are its advantages ?
    4) When i used kies in PC , it says, my firmware cannot be updated, why is this so ?

    Please help me with these questions, it will be really helpful. :-)

    THANK YOU..!!

    • yes , just updating won’t void the warranty, yes adter reboot you will get the language selection options! yes you will not be able to update via KIES as there is no official update yet. to get the update you will have to update with odin!

  43. One thing that is assumed, but needs to be mentioned, is that you *MUST* have installed KIES and it’s device drivers!!!

    Since I only use Windows when forced to (ie. for things like these firmware stuff) I didn’t have KIES installed, and I had troubles getting ODIN to see the Galaxy in the firmware mode.

    Also: Note that this doesn’t appear to work with a VMWare Fusion in MacOSX ;)
    (You need to be running as native Windows ;()

  44. When we do the wipe data/factory reset, this will remove all data on the on-device sdcard storage of the phone right? meaning all the application files and data?

  45. my sgs2 is xwkf1 and i haven’t update yet,im having that pink spot problem on my camera,can this xxkg6 update solve that problem? and can i update directly to xxkg6? pls reply,just a newbie here…thanks

  46. Maybe I asked a very long question…

    In short, can you provide me the link to download “KF3″ version for Samsung GSII ? (GINGERBREAD 2.3.3 –KF3″)

    This is the latest official KIES release.

    • no, its not a kies official version for your region!

      • OK, then can you please tell me the OFFICIAL version for the SGSII in India?
        Is it GingerBread 2.3.3 XWKE8?

        Can you please give a link to download the OFFICIAL version of the Firmware?

        Thanks in anticipation for a speedy response to my Q, as I need to take in my phone for warranty support on the battery,

        Appreciate the excellent advise you give.

        • Can you please answer my question please ??

        • from where you are from and to which version you were on previously?

        • I am from India and I would like to know tell OFFICIAL version for the SGSII in India?
          Is it GingerBread 2.3.3 XWKE8?

          Can you please give a link to download the OFFICIAL version of the Firmware?

          I am presently on GingerBread 2.3.3 DDKE2.

          I want to upgrade to the latest OFFICIAL version which is KIES supported.

          KIES is an extremely badly tested program and does not work properly with Win7 64 bit
          Please HELP

  47. Hi Neal Pradeep,

    With reference of last mail please answer, “The official KIES update that is available for the GS2 effective 1Aug11 is “GINGERBREAD 2.3.3 –KF3″If you can make the “KF3″ version ava for download and flashing, it will help”,because i am also from india and currently using XXKG6 Gingerbread 2.3.4 Firmware.And i need an official stable firmware ,that can get updated from kies(india).thankfully now i dont have any issues with the phone but i need GINGERBREAD 2.3.3 –KF3 or any latest version which supports (india)as a backup just to clam warrenty if something happens….


  48. Hi NeaL Pradeep:

    With reference to the same question, I too would like a link to the official version available in India.

    I am informed by local Samsung service center that the out-of-the box phone is “BUILD No:GINGERBREAD 2.3.3 – XWKE8″ with KERNEL VERSION root@DELL101 #2″.

    In-short “WKE8″. I ratified this, at the Samsung outlet, checking out a brand new display phone.

    The official KIES update that is available for the GS2 effective 1Aug11 is “GINGERBREAD 2.3.3 –KF3″

    If you can make the “KF3″ version ava for download and flashing, it will help.

    I have a battery issue, which needs to be replaced in warranty.
    If Samsung sees a different firmware other than that officially released, they will refuse warranty.

    Hence the friendly technician at service center suggested to roll back to official version, submit the phone, get the battery replaced FOC in warranty and then re-flash any version you want.

    To honor warranty, Samsung needs the phone to have the officially released firmware or the one released by KIES.

    By the way, I use your recommended GINGERBREAD 2.3.4 XXKG5 which is official Polish update and it really rocks!

    I am told that even XXKG6 is available? Is it better than KG5 or should one simply wait for 2.3.5?

  49. Ya, but how i can update with that.i mean, where can i get the latest firmware?only thing is it should be official stable firmware ,so that I can get updated from kies?

  50. What about XXKF2 Gingerbread 2.3.3 Firmware?

  51. Is there any way to install a official stable firmware again, so that I can get updated from kies?

  52. Hi,
    Can you please tell me which if the latest Gingerbread 2.3 firmaware image is available for the Samsung I5510 (slider phone) – Galaxy 551 as it is called..
    The current Firmware is Froyo 2.2 DDJK4. I am having severe probem of the WiFi disconnection and read that the new update will resolve the issue.

    Please indicate the correct ODIN to use as well.


    • as of now Samsung I5510 (slider phone) – Galaxy 551 hasnt got any update but as soon as it arrives, we will surely come up with the same

    • just follow the instructions ans then you will easily able to update!

      • I am having severe problems with the inclement WiFi connectivity. This is a well known issue with the I5510.

        There is a site where you get the updates too viz:

        I am reliably informed that the European firmware works and resolves the issue and a couple of my friends did have success in this matter.

        However I would prefer to go by your advise as regards the stability and effectiveness of the solution to resolve the WIFi issue.

        I value your advise, as it is most balanced and aimed at a stable phone.

        Grateful for your revert.

  56. Hi I have updated my SGS 2 with this firmware i.e. XXKG6.

    since then my internet is running slower. is it known issue ?

    and also on android market for most of the section is displays no matching contains found for your device.

    Can you please help me in this.

    Is there any way to install a official stable firmware again, so that I can get updated from kies. because for this firmware kies shown “this firm ware can not be updated”.

    Thanks in advance.

  57. Can I upgrade even if I don’t have an unlocked phone? I bought it from a mexican operator called telcel, I’m already running xxkg2 but I saw that xxkg3 can’t be updated without an unlocked phone, it’s the same for xxkg6?

  58. Hi Neal,
    I tried installing the XX firmware on my Chinese phone again for the second time, yet it failed. I have read on other forums that Chinese S2 can’t be flashed with XX firmwares. Could you please advice if there is a solution for this?
    Thanks, Krishna.

    • Here is the forum I was talking about:

    • which error you are facing?

      • The installation fails and on the phone screen it shows “software update fail”. Even after switching the phone on and off, it shows the same screen. However, the download mode still switches on.

        It seems like all the China phones have this issue. Please advise if there is a workaround for this.

        Aparantly there is a solution for this. Some guy posted the procedure in Chinese language but it seems like it is a custom version or needs rooting the phone. You can find the chinese thread here: Used chrome to translate it to English. I couldn’t understand the procedure as I am don’t have much knowledge about the latest phones. May be you can understand better from it.

        Regards, Krishna.

  59. hi,

    Baseband version

    can i do this update directly as mentioned in ur steps?
    and will i be able to download new software updates from samsung from my phone itself

    plz reply i reali wish to update and im lost with all this

  60. Neal, the first time I did follow the above procedure and got he phone almost bricked. Are you sure the Chinese i9100 can be flashed with XX firmwares?
    Thanks, Krishna.
    PS: Should the “Re-partition” box be left unchecked or checked??

  61. Neal, IN KG1 version i got the gtalk video but lost when updated to KG6.Please advice.

  62. So, these firmwares go like this ? From KG1 to KG2 and so on, with KG6 being the latest one as of today ?

    Second one is – Can I update from KG1 to KG6 directly ?


  63. Neal,
    I have updated the SGS2 from KG1 to KG6 but lost the gtalk video & voce talk. Please advice.

  64. is this update reducing battery life?? please update ?? will we get the social hub and the game hub and the readers hub in the update ??? please advice

  65. Hi Neal,

    Here is my story: bought a new S2 in Shanghai, China. I am totally new to this phone or Android platforms. Today followed the steps you explained above and got the “Software Update Fail” error code. Now whatever I do, that’s the only message displayed on the screen.

    However, I should say that if anyone followed the above instructions, the “Re-partition” box becomes automatically checked. And, I don’t see you mentioning to uncheck it in this article, so I went without deviating from your instructions. Later in a previous article I saw that you advised to uncheck the box. However, I am not sure if that’s what is causing the problem.

    I am still able to restart the phone in Download mode though. I tried to re-flash following the same steps while unchecking the “re-partition” box, but no success yet. Also, Kies can’t detect the device now (installed Kies after facing this problem). I have tried it both on Window7 and Vista Home without any success.

    Please help me, this is my brand new phone and I haven’t even used it for a day. :’(


    • if you are unable to get into the download mode then you need to visit the Service centre to fix the same

      • Neal,

        I realized from other forums that this is the problem for all phones bought in China mainland. Can ONLY use Chinese firmwares on these phones. HereBy the way, I did have access to the “Download Mode” all along. So, I followed your article to flash Chinese firmware: and it worked like a charm. Thank you so much for that article!!!!

        Now it is fine, except that I am stuck with a different version of the firmware, which is the China Unicom version. My original version was the Retail version. Would like to get back to my Retail version. Any help is appreciated.

        Also, the problem with Chinese versions is that there is no Android Market App, google mail, etc., unlike the western versions. Help here is also much appreciated.


        • Actually, I would still like to flash with a western firmware. I am sure there are hundreds of others in the same situation as I am now looking for the same. Please let me know if there is a way around to flash a western firmware on a Chinese i9100.


        • thanks krishna for the update! you can proceed for updating the version which is mentioned above!

        • I got a way to get around this.

          I just figure it out that if you have sucess flashin anything with odin, you unbrick your phone.

          For example if you flash the genuine chinse modem.bin only it will unbrick the phone, the same happens with anything that you sucesfully flash, if will make your rom useable again.

          Look at post #30 and you will see a way to install the western rom

  69. Hi Neal,
    i updated my S2 as you instructed above, everything looks good. i could see the Version change in Settings.

    but after update, i had completely charged the phone. now almost i have used for 4 hrs, 50% of the battery got drained and its draining faster. do i have to do anything else?

    in my previous Kies version atleast battery was there for 20 – 30 hrs. but now it looks like doesn’t last for 12hrs.

    • Hi Neal,

      Any Updates???

      atleast may i know how to reverse back to the same version of kies (which i had earlier)?

      • you can reverse via KIES, you will have to manually update the phone viA odin!

        • Neal,

          Before Reversing thro Kies, may i know about the battery problem in this version? second time i had fully charged and it doesnt last for 5 hrs…

          shall i install XXKG3? will it help? any suggesstion?

        • Hi Pradeep,

          Kies says the version of the device can not be updated. may i know where is the option to reverse? please guide me.

        • Neal,

          ok fine.

          finally 2 questions.

          1) if i update with XXKG3 will solve my problem? or
          2) how to update manually the official version (where to download the files from) to get sync with Kies.

          thanks for your help as always.

        • Neal,

          here is the update, i just downloaded XXKF2 2.3.3 and installed manually in the phone. but, phone didnt startup.. it got struck in welcome screen alone. so, finally i downloaded the XXKG3 2.3.4 version and installed.

          the phone is working. but the same problem the battery doesnt last for 12 hrs. usually in the official version, if we didnt use the phone, it will be in ideal mode, when in ideal mode it doesnt consume more than 5% of the battery. but in this 2.3.4 version it consumed almost 60% for 8 hrs.. with default application.

          if you guide me to install the kies version XXKF2 2.3.3 is highly appreciated.

          thanks a lot.

  70. Have an SGS2 updated to KG3 using your previous tutorial. Had used CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.tar thereafter to gain root, then flashed back the official kernel (Kernel Official Version XXKG3.tar) and used the usb jig to make my download custom rom count zero. Thus had obtained root as well as the kernel being “Samsung Official”. My question is …. can i update to KG6 using your method above, use the same CF Root kernel to gain root and then use the kernel provided in your guide?

  71. I want to know if this new firmware update will improve the battery performance of the phone
    Coz right now, it only last for about a day with medium usage ….

  72. are there any changes from the kg3 update…so far i cant tell any difference….once again great tutorial
