    @itskapil:disqus, I had ICS 4.0.3 (DXLP9) installed in my SGS II (GT-I9100) a week ago but the only problem was it had faulty sound effect problem, explained in this video

    I searched on the internet and found out that the problem might be related to the ROM so in order to change the ROM, I updated the ROM to ICS 4.0.4 (XWLPO) from this thread But it did not resolve my issue so I decided to downgrade from ICS to GB and installed this stock rom from above guide in the hope that the would solve the problem but the problem is still there, a little bit solved, as the music from the speakers of the phone is working fine but when i connect handsfree the voice of the singer is too low and almost not hearable. Please guide me as to which rom I should install to solve the problem.

      Hey, don’t worry… it will be okay… first confirm to me what’s the model number of your Galaxy S2, is it i9100G or i9100 (check under the battery if you can’t find anywhere else)…

      If it’s i9100 only, follow the above guide again.. you’ll be okay if do all the steps with little bit of care.

      And of it’s i9100G, I’ll get you another link which will get your S2 back to working. Let me know.

    I have an SG2 and I’ve tried this about 4 times, and each time it stays frozen on FACTORYFS.img

    I now have no phone and you can say that I am freaking out. My provider is Bell and I have not been able to do a factory reset either. It says that there was a connection error. Can you help me out here?

    To check with you, in the video it is shown for google talk, video and voice chats are enabled.

    How come in my S2, I cannot find video and voice chat feature? Do I need to change any settings for this or am I missing something obvious?

    • Kapil

      Oh, Sammy removed it from their latest firmware. I’ll get you a hack for that!

      • Anonymous

        I would appreciate that.

  • Robson Alves

    Just FYI, this procedure worked just fine on my SGS2 M250k (Korean Version). Didn’t have a single problem!

  • Vinniemanjarro

    Are the 3 remaining files needed? (the ones not used in ohdin). if so what for?

  • Ramón Lima Batista

    Guys, do you know how can I downgrade to KG1 or any other 2.3.4 build? my phone’s been rebooting a lot during the night. And my GPS doesn’t seem to be working.

  • Geert

    In other posts on the internet, they say you have to clear the cache in recovery mode, you didn’t mention that in the user guide, should I clear the cache or leave it like it is

      No. Not needed :)

    I have a Samsung S II which is 4 days old. Battery life for my phone is not satisfactory, I need to recharge on a daily basis.

    If I upgrade my firmware to XXKH3, would it improve my battery life?

    I have the following baseband version for my Samsung S II.

    Baseband I9100XXKF1 and phone model is GT-I9100.

    Besides could it be possible to upgrade my firmware to XXKH3 directly without updating previous updates ?


    • Kapil

      Yes, you can upgrade your phone to KH3 — your phone is eligible. But, do not expect improvements on battery life — it could be all same, if not better or worse.

        Thanks for the quick reply, I would try to upgrade my firmware.

        Are there any ways to improve my phone’s battery life?


        • Kapil

          If you’ve too many apps installed, especially that run in background and also those apps which continuously update, like widgets, consider removing those apps. For example, anti-virus apps, weather apps, Live score widgets, etc.

          And turn off wifi, gps, data connection, etc when not required. Low brightness also improves battery life. And use other common ways! That’s it.

            I successfully upgraded firmware to XXKH3, however my 3G is not active even though I tried to activate by pressing power button.

            How could I enable 3G?


          • Kapil

            I think you need to put back the APN settings, these often get lost after a new firmware is flashed.

          • Anonymous

            It was my mistake, I forgot to put APN settings back.


          • Kapil

            No probe :)

            No probs :)
