  6. hi bro,

    your article is very helpful.. helps a lot to me on FW upgrade.

    btw i wanted to ask about viewing videos on samsung galaxy s2. do you have any recommended player app which can directly view any .avi files fom my PC without any conversion? i tried to convert my .avi to .mp4 but doesn’t work well. when i open it on the default video player, it only plays 1 min and after that it says “file error”. i tried it on different files but got same error.

    thanks in advance for any tips you can give.

          • I just have a small silly doubt.I am already rooted on stock ROM on Gingerbread using CF Root.If i upgrade to ICS,do i have to first unroot my GB to stock and then install ICS?If not,will I lose my root after flashing the ICS firmware directly?Also my kernel is XWKF3.Should i use the same file as yours?

  8. Hi Jayce,

    Just bought SG S2 two weeks ago. I noticed my S2 device is facing major problem, Automatically turn on Flight mode problem when make a call and make my call are being dropped and again after deactivate flight mode function after few seconds..

  12. Samsung kies is installed but it also not detect my device. should i install kies again. also give me the link for latest drivers which r required.

      • solved it by flashing on another pc. But i want to do it on my own PC.
        I am Confused whats happening with my PC.
        Now I have run KIES and now it detects my phone and i have made backup.
        But the real problem is that it happens sometimes and sometimes it does not happen.

      • So are Custom Firmwares available in TAR Format ?? which is supported in ODIN … I asked you this question because whenever I go to .. a Custom Firmware Page on .. XDA .. etc.. The 1st step mentioned there is “1st of all you need to have a rooted DEVICE” and then they go on blah blah .. about soo many things .. whereas your instructions are soo Simple and Concise .. (straight to the point) .. so I have vouched to follow this Thread.. 🙂 but I really need to be clear .. From where do I get Custom Firmware which I could ADD in Odin and Directly apply to my Device without Rooting it … (of course I know that after the Firmware is installed the Device will be rooted) my query is .. whether I could start off without applying CF ROOT.. and Clock work Recovery.. mod .. ?
        Much obliged to your solutions .. JAYCE ..

  15. hey can this help to change baseband version too if cant is there anyother solutions because i want to update it to chinese firmware so thati could use it in chinese too.

  26. If I were to install XXKG5 from XXKH3 (Frankenstein firmware) in my Galaxy S2 thru Odin, do I need to wipe my data & cache? Or is it better to just leave it and wait for new updates? Can’t seem to get Google video chat even on 2.3.4? Im on XXKH3 now.

    By the way, I’m hearing echos of my own voice during my calls, is there a way to fix it? I’ve googled but can’t seem to find a straight answer

  42. dear Mr.Jayce,

    I have just got an unlocked brand-new SGS2 from ChinaMobile operator where I live ( did not use it yet )

    I have already gone through all the threads above, and became happy to find an expert like urself who’s been able to help most of them

    my problem is that – although they changed the settings to English – I still am getting many messages in Chinese ( which I don’t understand being an Arab )

    the most am interested in are the following three:

    1. GPS with English map and English narrating ( I mean the voice commands language )
    2. to use Viber
    3. to enter the world of Android softwares like free programs and games maybe

    can I change from my firmware to an English one?

    Model number GT-I9108
    Android version 2.3.4
    Baseband version I9108 ZMKH6
    Kernel version 2.6.35.7 se.infra@SEI-27 #2
    Hardware versioin I9108.01
    Build number gingerbread.ZMKH6

    I prefer to change the firmware to English using Kies, Would that be possible ??

    Thank u in advance.

      • thx 4 prompt reply …

        I9108 is still SGS2 , isn’t it ? and which one is better I9108 or I9100 ?

        can u pls help me out though

        I’m so much grateful.

        Unfortunately, in China u can not open utube, thus I couldn’t watch ur video, even with ultrasurf

        is it uploaded onto any file share site by any good chance?

        Thx a million

          • appreciate ur prompt reply

            would you be so kind to me referring me to some link or someone which can help me out; am very new to the domain of smart phones ( it’s my first one actually )

            I almost do know nothing about ur Jargon ( Brick – root – ROM – flush .. etc. )

            yet am a bit confused … this post is for SGS2 and mine is SGS2 something am sure about.

            may god bless u Jayce,

            • SGS2 has lot of models like I9100, I9100G, I9100T and US versions too. You can only use the stuffs developed for your own model.

              I google I9108 and couldn’t find English website that has more information about it. Most Chinese. Sorry…

              May God bless you too, Hussam. 🙂

              • Thx a lot 4 ur continuous knowledge contribution and expertise volunteering Jayce.

                Today, I went to Samsung service center, and Mr.Feng – there – was wondering whether exchanging my device with an I9100 one, would solve the Chinese language problem. Would it ??
                ( He says I9100 is Chinese too, and with much less features than I9108 )

                What do YOU think Jayce ?

                I mean is it like I can get a firmware compatible with I9100 which is developed for ENGLISH speaking countries ?
                You are the man Jayce 🙂

  86. Hi,
    I cannot get my SGS2 connected to PC, despite usb debugging, usb connection enabling etc etc which are suggested by some forums.
    So I am not able to upgrade!
    Any ideas how to fix this problem?

  87. I managed to upgrade the firmware to 2.3.6 XWKK5 using mobile odin.
    It flashed smoothly.
    Now the phone shows:
    Android version:2.3.6
    Build number: Gingerbread.XWKK5
    Kernal Version:2.6.35.7-I9100XWKK5-CL754841

    However, the baseband version is still: I9100XXKG6 ( I HAD XXKG6 firmware installed before current upgrade). Is that OK?
    Also, the sound is quite distorted right from the bootup.
    I am still unable to get connected to PC.
    BTW, I did a factory reset, but my wall paper is still there.
    Please help.

  89. Hi Sir,

    I just wanted to know if i update my phone to 2.3.6 using your method will i still be able to update to 2.3.7 or 4.0.1(if any) provided by Samsung through Kies ? Also do i need to root my phone before using Odin to put 2.3.6 ? And does manually updating would put any bloatware or any other additional app which is unrequired or not in english?? And is this update be ok for an indian version of S II which is still officially stuck to 2.3.3?? Also is this a global version of 2.3.6 or a region specific update which would be pushed to other S II ??

    SORRY FOR TOO MANY QUESTIONS !!

    Also a quick reply to my queries would be appreciated… Thanxs in advance !!

    • Yes but from Europe region firmware. No root access is needed. It will have apps for Europe. Yes, as long as your SGS2 is GT-I9100 model. Not global but for that region only.

  94. Probs updating to Gingerbread 2.3.5 via Kies & Win 7

    Hi Jay
    I’m having probs updating my S2 to 2.3.5 (the latest available, here in Italy with my provider .- from Gingerbread 2.3.3). This is the routine:
    1. I connect the phone, start Kies & then I get the message saying a firmware update is available.
    2. I click to accept & Kies downloads the update (tho I think it disconnects the phone in the process).
    3. A window appears saying Kies is preparing the update, but here it seems to freeze up.
    4. Whilst this is frozen, Kies (in the background) presents a msg saying a new firmware update is available (as in point 1, above).

    Kies is up to date (in fact I’ve updated it 3 times & installed/uninstalled/reinstalled each version – same result).

    I also download ODIN 3 v1.85 (to try as per your vid, above), but it crashes as it opens.

    I have a Windows 7 32 bit on a laptop & a dongle internet connection.

    Any ideas?

    Thanks in Advance

I have flashed my samsung galaxy s2 via odin using single file I9100XWKL1_I9100ODDKL1_INU but it did not delete my previous apps, moreover the factory reset is just deleting my apps not sd card data though I have selected to erase sd card data too..Last time when I have flashed for 2.3.5 it had 3 files and it was a fresh install asking me to enter email id and time after installing the firmware but this time it did not happen….can you explain me what is the difference between flashing using single file and flashing using multiple files…????

  108. Hi,

    I followed the instructions in ur website to flash the ROM of my galaxys2 with one of the Frankenstein firmwares given in the http://forum.xda-developers.com/showthread.php?t=1075278 website. My vendor (Bouyges Telecom, France) currently provides Ginger bread 2.3.4 version . But I am running a Frankenstein firmware version of android 2.3.6. Now i just booted in the ODIN mode to check my firmware version and binary count. It says “samsung official” and the count is still “zero”.
    However,,, Samsung keis does not recognize the firmware of my device for updates. So my question is ,,, will the warranty for my device be void ? ? Could you please give me some information on this?

    Thanks,
    Venkat

      • Hi,

        Thank you for the reply. I have few more questions. So ,, if you say mine is a Custom ROM (my ODIN download mode shows that I have Samsung Official Rom and Custom Binary counter is still 0) why is my Custom binary counter still showing 0 count and why is it still showing “Samsung official” firmware? ? What does that mean then ? As i told u mine is a Frankenstein firmware running Android 2.3.6.

        So does this mean that,, if i have to flash my firmware back to original vendor provided ROM, I dont need to reset this Binary counter using a USB Jig (since mine is already showing 0) ? And I ll safely be entitled for to my guarantee again ? ?

        Thanks,
        Venkat.

  109. BASEBAND : I9100XXKF1
    KERNEL : 2.6.35.7-I9100XWKF3-CL276555 root@DELL101 #2
    BUIL : GINGERBREAD.XWKF3

    How to update ? what is the correct Firmware to download ? Thanks !

  111. Does firmware upgrade of reinstalling of the same firmware will remove the applications? I have some applications which are giving problem to me and I cannot remove them through the phone. How do I remove these applications?

  113. Hey Jaycee,

    I bought my phone in China 2 weeks ago and I would like to change it to any firmware but from what I understand a lot of people brick their phones! Since I usually use gmail and want to use the english version of android market. Is it safe to do it your way? I have no knowledge so I’d rather ask before I do anything with my new phone. I hope you can help me

    Thanks in advance,

    Loic

  114. THANK YOU SO MUCH! I kept flashing my phone (that was stuck in bootloop) with the XXKG1 firmware, since I couldn’t acces the phone and go to “about phone”. So I looked at my dad’s SGS2 from maxis, and it said the firmware was XXKG1, so I thought mine would be the same since I purchased it from Malaysia (not in maxis though). But it kept being stuck in the bootloop. Then I tried your firmware, and that did the trick. So I’m guessing Maxis gets their phones from USA or Europe and not from asia since XXKG1 according to XDA is not from asia, it’s from europe. Hmm strange. Anyways, thank you so much! Keep it up!.

  116. Stuck in boot.bin means you forget to enable USB debugging mode in setting – Application – Development. Hope it helps

    And if you don’t want to install KIES in your PC, you have to install Samsung mobile USB driver in your PC so your PC can detect your SGS II

  121. hi, i bought my samsung galaxy s2 from online. it was brand new but from hong kong. i live in australia, when i plugged my phone into the computer to transport data it asked me to update firmware. when i clicked yes it got stuck on 10%. Now the phone wouldnt turn on anymore and samsung australia doesnt help me because they say its from hong kong and hong kong recovery firmware needs to be put into the phone. Can anyone help me with this….how can i get the firmware update hong kong version from kies???

  122. Thanks for all the help, i fixed my phone, but i lost everything i had in it :@
    its all back to factory settings :/
    at least i have my phone back though

  123. G’day,
    I purchased on eBay the Samsung Galaxy S2 Epic Touch that is CDMA hardwired for Sprint. I live in Canada and my server is Telus. I need to break the root and to unlock it. Can you help describe the steps necessary to be able to use my server and optionally stop using my old and slow?
    I am also unsure if I should wait for ICS as it has Gingerbread 2.3.6 but still unable to make any logical connections as still locked. I guess my main question is how to unlock it.
    Thanks bud!!
    Cheers
    Bob

  124. Hi Jayce
    I was using my Samsung galaxy S2 for a while and suddenly today all the contact is missing from the mobile. I am able to get a back up from Sim card and rest is completely gone. Could you please help on this !!!

    Thanks in Advance
    Visakh

  125. hi brother,i bought my unlocked samsung galaxy s2 from ebay and it was working perfectly for a month and after that stoped and when i went to the repair shop they told me that has been blocked by the company and i need to get in tuch with them and i dont know which company is that,is there is any solution please?

  126. hi jayce. i was using 2.3.5 xxki4 as suggested by you earlier.. it all went well.. n my phone is rooted as well.
    now if i wanna upgrade to xwkk2 2.3.6, how am i to do it.
    since its already rooted i don wanna take a chance. please help.

  127. Only 3 questions Jayce
    1.Have you tried Hyperdroid androidmeda ROM 2.3.6.?How is it?
    2.If I have to install it,should I wipe data/cache first always ?If I dont like it,instead of flashing stock firmware again,can I just restore my stock image through NANDROID?
    3.what do you suggest?installing rom through CWM recovery(sdcard) or ODIN?
    Please reply.thanks

      • Thanks,so I assume that restoring through NAND(CWM) is alternative to flashing stock firmware(in fact better,since it will even come up with apps installed;while I’d have to reinstall apps using TB in latter case)

        Which custom ROM(official) do you think is best?(battery saver too)?

  128. hi was downgrading my sgs2 and it was stuck i put out the bettery and then stuck in a phone and a pc picture with triangle in middle what should i do now help me out thank you

  133. Hi Jayce,

    Thanks,

  134. hy bro i wanted some help i m usine s2 and its on custom rom of gingerbread 2.3.6 n when i connected it to kies kies says your device does not support upgrading via kies how can i solve this upgrade problem

  135. I have bought Samsung Galaxy S2 in the Netherlands last year. I live in Thailand but I did not want to risk counterfeit. Because of an accident the motherboard had to be replaced and loaded with Asean software with asean languages and English. But I like to have european software.
    Currently I have on the system:
    Kernel version: 2.6.35.7-I9100DXKI2-CL564948
    root@DELL129#2
    Build number: GINGERBREAD.DXXKI2

    I have downloaded:

    Downloaded:
    I9100XWKK2_I9100XENKJ1_XEN
    Kernel_I9100XWKJ3.tar.md5
    SS_DL.dll

    or:

    GT-I9100-CSC-MULTI-OXAKL1.tar.md5
    MODEM_I9100XXKL1_REV_02_CL1085162.tar.md5
    u1_02_20110310_emmc_EXT4.pit

    Is the latter suitable to install on the phone by following your routing tutorial? Which files do I need to install?

    thank you in advance

  138. Guys, can any body help me? I´m trying to extract the ICS 4.0.3 firmware for SGS2, and it always comes an error, and the file desn´t unzip… Is there any other program i can use? Please help me, i want to try ICS….

    Thanks.

  141. hi jayce i have a got an orange galaxy s2 which is unlocked and is running android 2.3.3.i wana ask that can i flash it with any official samsung firmware that is for generic s2 not carrier branded and secondly will my phone b locked again after flashing it with upcoming firmwares??

    • Hi Ahmad, I wish that I know the answer. But I don’t have locked SGS2. Not so sure about it. Maybe you can refer to others at XDA website who have the same model as yours. 😉

  142. does installing he firmware thought the official one from odin does this mean i have rooted my device will it invalidate my samsung support.
    thanks for the reply

  143. Jayce, I am back again.

    I bought a Samsung Galaxy S2 I9000 in the Netherlands, SIM free. When the phone had an accident the motherboard needed to be replaced. This was done by Samsung Services in Thailand since I live in Thailand. So now I have an Asian version which I do not like at all and is not so handy.
    I have rooted the phone, Kernel version: 2.6.35.7-I9100CEKI2-CL586309, root@DELL147#2, GINGERBREAD.DXKI2. I like to download an European version software or Dutch version.
    Searched for and found a few that I think that might do the job:
    XWKK2: PDA:XWKK2, PHONE: XXKI4, Date: 11/11/2011, Android 2.3.6
    XEN (Netherlands), XWKK2 Stock Kernel
    XWKJ3: PDA:XWKJ3, PHONE: XXKI4, Date: 25/10/2011, Android 2.3.5
    XEN (Netherlands), XWKJ3 Stock Kernel
    CEKI2: PDA:CEKI2 ,PHONE: XXKI1, Date: 19/09/2011, Android 2.3.4
    XEN (Netherlands), CEKI2 Stock Kernel.

    Now I have a few questions:
    1. Which version would fit my situation best?
    2. Or is there a better version?
    3. Do I need to download the stock kernel as well?
    4. Or will just downloading the CSD do?

  145. follow your steps and successfully install stock ICS. before this, i’m using miui on my sgs2. keep up the good work jayce 🙂

  146. Dear Jayce,

    Thanks brother, going through your replies I could get the solution to successufully install latest released 4.0.3 for Bangladesh. Thanks again, keep it up. I think I will often fall back to consult.
    Regards

  147. what if i install official europian firmware in india will this be considered root. please help iam about to install the ics firmware you have on your website. thank you for your reply.

    • Install official firmware with Odin is not rooting. Because you still don’t have root access after installed it. But install other region firmware might void warranty.

    • blue themed ics is vanilla. means what you see on galaxy nexus is original ICS theme. if you flash your SGS2 with firmware above, it comes with samsung stock interface, hence the green icons.

  151. Guys.. the ODIN does not detect my SGS2 while in Download mode.. In normal mode it detects.. I tried to enable/disable USB debugging.. tried to kill the Kies process.. Nothing works.. Any help will be appreciated..

      • I have downloaded the …..tar.md5 and odin .. I connected the phone to pc in regular mode and started ODIN, it detected my phone.. I then went to download mode.. But odin does not detect phone, PC searches for a serial port driver and does not find it.. As per google, I installed samsung composite drivrrs, but no use.. I tried to enable/disable usb debugging.. Killed the kies processes in task manager.. No use..

          • No jayce. The phone does not get detected in odin download mode.. Thats the issue here.. What I meant was.. When the phone was connected to the pc in regular mode (not in odin download mode).. I started the odin exe jus to check..and I saw the yellow com… Then I restarted the phone by using volume+home+power button, the odin download mode came up.. But the yellow com disappeared which obviously means odin cannot detect phone in downld mode..instead the pc asks for a driver for the serial port..so I installed some driver called samsung component driver.. But stil it asks fr driver.. I browsed thru and saw suggestions like usb debugging, killing kies, restart pc.. I tried all of that, but to no use..

  153. hi, i was just wondering, if i install the official EU ICS4 update (i am currently using the official 2.3.4 update i got from kies) but i am in south Africa, will i still be able to use kies and does this root my phone?

    p.s.. is there a downside to this?

    • Samsung Kies should work fine on official Europe ICS firmware (but I did not use Samsung Kies personally. So not so sure). No, install official firmware does not root your phone.

      ICS firmware is still not 100% perfect yet. And certain apps cannot support ICS yet.

  155. i have recently bought a samsung galaxy s2 GT-I9100 and have been having trouble with vlingo operating when it shouldnt and basically taking over the phone and running it flat all by itself. i was wondering if its possible that i can update the phone so this won’t happen or if you had any solutions. my phone operating details are: Android Version 2.3.4 Baseband Version I9100XXKI1 Kernal Version 2.6.35.7-I9100XWKI4-CL575468root@DELL143 #2 Build Number GINGERBREAD.XWKI4 . I was also after any specfic information like the region details and what it all means and the best system slash thing i can do thanks in advance

  157. I tried following all the steps provided above but the Odin isn’t uploading the update
    Please what can I do as I am afraid my phone might not work if I should disconnect

  160. Hi Jayce!

    Thanks for the instructions.
    I wanted to upgrade my SGS2 firmware to 2.3.6 and started following your instructions.
    But i seem to have downloaded the wrong file. I d/loaded it from http://skywanker.net/download/download.aspx?link=GT-9100/Kernels/Kernel_I9100XWKK2.7z
    But nothing happened when i unzipped this file and used it in Odin.
    Can you please locate the exact URL for downloading the firmware for 2.3.6?
    This is kinda urgent.
    Please help.

    Thanks,
    Suresh

  161. Jayce, i have a SGS2 with

    I have currently ICS on my SGS2 (what I flashed with your instruction guide without any difficulties:).
    As I don’t like ICS I tried to revert back to Gingerbread 2.3.6. (I followed your instructions step by step.)

    Any ideas?

    Many thanks,

    Sara

  173. I just have a small silly doubt.I am already rooted on stock ROM on Gingerbread using CF Root.If i upgrade to ICS,do i have to first unroot my GB to stock and then install ICS?If not,will I lose my root after flashing the ICS firmware directly?Also my kernel is XWKF3.Should i use the same file as yours?A bit confused here.Are the ICS kernels different for different countries?

  174. I just bought this SGS2 I9100G. The agent that sold me this phone claim that it is an export set. When I tried to change the language to chinese, I couldn’t find it in the language section. I tried following your instruction to change CSC but it only shows XEF, no other selection available. I tired upgrading the firmware thru Odin but it keep showing Setup Connection for quite awhile then it shows COM Port cannot be opened and a RED FAIL! shown. My USB debugging already turn ON. I had tried using all my laptop USB port, still the same problem. Pls help, I urgently need this chinese language, any other solution? Many thanks.

  175. Hi Jayce, I just received a ss2 phone for my birthday… and have no clue how to remove certain apps and install apps from .apk. So i googled, found out some info and thats what leads me here.

    Checked through all the menu on the settings and non reveals how to install/remove apk files. So i thought if i could remove the entire os and put in something that have the full settings unlocked rooted… but it still needed to enable the usb through application settings to root. But, i dont see the word “applications” or at least anything similar. I assume maybe be because its not rooted or already installed with different firmware, removing the os and replacing it with the common rooted one would work. Not sure, since im new to android…

    Im not sure of “markets” i hear alot, but i do have downloaded apps at my pc. I cant sync my usb to kies either, but the pc reads the storage device well ( yet still as unknown device). My pc is on win 7 and tried installing the drivers separately yet still not recognized exception to mass storage mode.

    Here is the “settings” assuming it is the wheel like screw icon.
    (http://4.bp.blogspot.com/-J2mWNfFgvr8/T6UWVJw2HZI/AAAAAAAAAp0/NBaMxl8Owpo/s1600/050520122721.jpg)

    Here is the First thing i see on the settings menu as above :
    (http://2.bp.blogspot.com/-YiTLBqXhkaw/T6UWeyT_bYI/AAAAAAAAAp8/91sOsG-wCO8/s1600/050520122726.jpg)

    The other Menu in the Settings are, Phone and Connection and both has not much choices.

    Not sure how to check “about phone” details either since that choice is not there,

    lastly, the back of my ss2 battery shows :
    model : gt-i9100
    ssn : i9100gsmh
    (So it has a “G” right? i think at this rate im gonna wreck my ss2, since it has some totally unwanted apps in it…)

    Sorry for the long probably silly questions, im still learning, just had it for 2 days. thanks in advance 🙂

    ~Shara

      • Well, i wanted to uninstall some apps. i couldnt. thought it was old firmware, so i decided to remove the current firmware, and add a new firmware and get the root access to it. not sure how exactly when i cant access the phone details or the recovery menu at startup.

  177. Hi jayce, if I want to go back to stock from pics 4.0.4 custom rom with custom firmware, I only have to flash the stock firmware to replace the custom rom and kernel as the stock firmware has the stock kernel with it right?
