Download Android 2.3.7 Gingerbread ROM for Samsung Galaxy S2 (CWM)

CyanogenMod 7 for Samsung Galaxy S II may not be the most stable ROM. It is still in nightly development stage. But due to that, you can try the latest Android 2.3.7 Gingerbread GWK74 on Samsung Galaxy S2 now. And it is using XXKI3 baseband from latest official firmware.

Software information

cm_galaxys2_full-72 build was the version that I tested. It is based on Android 2.3.7 Gingerbread. I believe all the future build will be based on Android 2.3.7 too. Hopefully, CyanogenMod 8 with Android 4.0 Ice Cream Sandwich will be coming out soon…

Note – This is a nightly development release. Do check out CyanogenMod website for latest build.

    Hello Jayce

    I got a Samsung Galaxy S2 from China mobile. But all the aplications, like tha market are chinese version, even the logos are different. Is it possible to format it and add another ROM version from any other country?


    • Nope, sorry… China I9100 hardware is not same as international I9100. So you can’t use any firmware / kernel for international SGS2.

    Jayce ,
    can i know how long do the process is ?
    i flash it and it never reboot untill now and the screen just showing samsung galaxy s2 gt-i9100 and a triangle exclamation mark .. how ?

    • Normally around 20 minutes.
      Try to wipe data and cache. Then install CM7 ROM again. If still cannot, try other Android ROM.

    Is Jkay theme can run in 2.3.7?


    • I prefer latest one.

      JKay supports up to XWKK5 now. No Android 2.3.7 Samsung firmware yet.

      • Calvin

        Is there a big difference between 2.3.5 and 2.3.7? I can’t really find an obvious comparison…

        How long do you think 4.0 full ver will come out…?

        • I did not try Android 2.3.7 on S2.

          Official Android 4.0 firmware will be out by Q1 2012. I believe end of March for Europe.
