  6. Hi Saurabh,

    I have a SGS2 gt i9100
    version 2.3.5
    baseband i9100XXKI3
    kernel version se.infra@SEP-55#2
    Build number GINGERBREAD.XXKI3

    My phone was branded and i went to a local shop that rooted my phone because i wanted to use other carriers to. Now i have Superuser on it i think it’s rooted i’m not sure i tested the phone with rootchecker and it tell’s me that is rooted.

    My question is i can steel use this firmware or i have to search another firmware for rooted SGS2. In Keys won’t upgrade and neither FOTA. I changed CSC from KOR to ITV and still doesn’t want on FOTA. ITV stand fot ITALY i use CSC SELECT. I have to mention that the phone isn’t from Italy it is from Romania.

    I’ll wait for your answer i thank you anticipated whatever the answer is.Sorry for my english i don’t speak it or write it that much.

    With respect from Romania,
    Thank you verry much
    Have a nice day

    • You can easily upgrade to this, but your root access will be gone after upgrading.. You’ll have to root your phone again using the root tutorial given on our website after upgrading.

      • Thanks for your reply i’ll try it i hope rooting isn’t so dificult.
        Thank you again. After update i will make you know if was o.k.

  7. Instaled, till now works fine no need root anymore works with all carriers i was expected since the firmwareis unbranded i’ll have to pay attention to the battery if performs better or not respect 2.3.5 i hope at least like the old one if not better, but it seems yet much stable than the gingerbread. Thanks for your reply, i hope that works to everyone. Have a nice day

    Thanks a Ton……… really appreciate the effort u put into this great tutorial.

    NO errors …my S2 feels New and seems will keep up and running for another year

  13. I flashed my S2 SHW-M250K Korean version with this firmware. I don’t know whether it’s successfully done or not! It took around 6 hours but odin didn’t complete it. It was stuck in the middle in “hiden.img” task. After 6 hours I unplugged my phone. Now restarting it shows “Upgrade” but nothing happening! Can you help me out? Should I flesh my phone again? How much time does it need while connecting via odin? I’m really confused that I’m going in a right way or wrong. I don’t want this Korean version. I want to convert it into international version. Plz help me.

    • Go to recovery mode and try factory reset option..

      • I tried to go on recovery mood but it doesn’t work however download mood works. So what I suppose to do? How much time does it take via odin would u plz tell me that?

        • It doesn’t take so long.. It completes within 15-20 minutes..

        • Oh.. Then it won’t work for me I guess! Today I tried it again & gave around 30 minutes but it stuck on “hidden.img” again! Now my S2 SHW-M250K semi-bricked! Should I try your another firmware as u mentioned on??:

          I’m really stuck! My cell phone isn’t working! If u can plz help me.

  14. Saurabh I’ve converted my SHW-M250K into GT-I9100. Android Version: 4.0.3, Baseband: I9100XXLS8, Kernel: 3.0.31-Siyah-s2-v5.0.1+gm@ubuntu #6, Build number: IML74K.XWLP8.

    Everything going good but the problem is the phone is becoming slow and hot after using 20-25 minutes. Moreover battery drains too fast! Should I try ur this official firmware again? What’s about ur battery life? How much does it sustain?

  15. which is better Or ??

  16. s2 is restarting on its own

    it comes unfortunately has stopped working

    Reply fast

  17. WORKED FOR ME! Thanks! :)
