Hey all, I just broke my old Xperia X10 and considering a new phone. The Galaxy S II looks great. I really like messing around with the new roms, but it seems the Docomo version is pretty restricted in what ROMS (particuarly Miui) and kernels can be used due to the radios I guess. I live in Tokyo and would rarely care to use 1seg. Not sure if an international version of this phone would have signal or GPS issues etc.

My question is, would you guys recommend to get with the Docomo SC-02C or go for an international S II?

Sc-02c is fine but you have to flash a special kernel and the default basband. The kernel in my sig works great for me. If you get the international version you will pay out the nose for data on docomo

Hi everyone.. I'm having problem with my sc-02c and i think it depends from softbank mms settings that dont allow me to download any mms. I just receive mms notifications from 920101 but no mms is donwloaded.. For that reason every 45 seconds com.android.phone error pops up freezing the sgs2 for 5 secs.
I tried several usim card and they all work perfectly execpt my old black sim softbank card. Is there a solution? I already hard reset it several times and I try to install mms.apk to fake UA settings for mms. The phone worked perfectly until 2 days ago now its f... annoying me... I dont have problem using mobile internet with softbank apn, calling /receiving phone calls(they must be really quick ones ) and sms work like charm...I dont know what do anymore. Thanx

OMKJ4 (2.3.5) is now official and available on regular kies plus OTA update.

Root is preserved with OTA update, no need to reroot.

(And yes, OTA is working for me this time too)

Thanks for the info, checking now. Strange, I always get the connection failed when trying to DL OTA, any ideas why?

Don't know, seems like about half the people it never works for and they're relegated to doing Kies/Odin updates (which takes many times longer due to the backup/restore of /data).

Oh, and be prepared for a couple minute wait on the first boot as dalvik cache gets rebuilt.

Difficulty downloading 2.3.5

Anyone else having trouble downloading 2.3.5 with Kies?
Maybe too many people downloading it right now but I am on my third attempt now. I didn't try OTA because I have always been asked what my Samsung login is and that never works no matter how I try to login.

Also... When oh when is there ever going to be a SIMPLE guide for rooting this thing properly step-by-step without having to bounce around 10-15 threads? Obviously keeping 1seg and GPS intact.
Now I guess we will have to wait with 2.3.5

    NTT DoCoMo SC-02C FAQ in progress, coming soon...

    Q: What is the difference between the SC-02C and other Galaxy S II models?
    A: The FM radio on the "international I9100" is missing, and in its place is an ISDB-T digital TV receiver. (Similar to but using a different broadcast protocol as the DMB receivers in the korean M250 models) The SC-02C does not have NFC capabilities, like all models except the M250.

    Q: How can I unlock the SC-02C?
    A: The unlock used for other early Galaxy S II models will not work on the SC-02C. You can have the handset unlocked at your nearest DoCoMo shop for 3150 yen (tax-inclusive). This does not supposed to affect your monthly billing.

    Q: Where can I find original SC-02C firmware if I need to return the handset for service?
    A: There is not an official version of the OMKF2 firmware that the earliest released handsets came with, however you may obtain a copy of the first update, OMKG5, here.

    Q: What is the current version firmware?
    A: The final firmware version is OMMP7 (Android 4.0.3)

    Q: What's the deal with tethering?
    A: If you use tethering (i.e. mobile access point) you may find your monthly pakehodai charge has increased to 10,395 yen/mo. Its suspected that turning the built-in tether feature switches you invisibly to a different APN which generates an increase on the bill.

    Q: How do I activate the Palette UI that Docomo is advertising?
    A: Use the 'Home Switcher' application or clear the defaults for 'TwLauncher' in Settings -> Applications -> Manage Applications.

    Q: Can I use I9100 images (and custom ones) on the SC-02C (or vice-versa)?
    A: To an extent yes, there are a couple issues:
    1. The kernel/baseband must be for SC-02C or else you will lose GPS/One-Seg functionality. (You can generally flash these back after installing a custom image)
    2. The SC-02C has a different partition layout, FACTORYFS is 100MB larger than I9100 and HIDDEN is 100MB smaller. The disk usage on the current OMxxx images does not exceed the size of the I9100 partition, however it is VERY close and the SC-02C's partition table was likely laid out different to allow for additional growth.

    The bad news is that Docomo firmwares do not contain an Sbl.bin file, so you can not fix your boot logo that way. The good news is that someone ripped the Sbl.bin file from their phone over a year ago, this one also works with the usb jig. So it's a win/win. You can download it from my DropBox go to the !SC-02C folder, download SBL-SC02COMKF2.zip extract it and flash the tar with odin.

    I did the same thing as you, this is how I fixed it. Also if you'd like to use the GPS/compass fix and get some nice tweaks as well, youy can flash my mod in my DropBox's Simmo's Mod folder. Download the zip file with Siyah in the name, and install with ClockworkMod.

    Good luck.

    hello, Im a user of Docomo SC-02C GS2, can u help me?
    I flashed a firmware of european model and now I lost the "Docomo" logo at the boot.
    I think it is because I had flashed the file includes "boot.bin", and "sbl.bin".

    Now I can flash the original firmware (from SC-02C_DCM_SC02COMKG5_SC02CDCMKG5_SC02COMKG5.exe) without problem.

    This is the current Version on my phone:
    PDA: SC02COMKG5
    PHONE: SC-2COMKG5
    CSC: SC02CDCMKG5

    Build Info: Sat Jul 16 06:05:10 KST 2011

    There is no problem to use the telefone.
    But at the boot of the telefone, it shows "Samsung Galaxy S2 GT-I9100". (Before was "Docomo" ....)

    Can you tell me how to rebranding to a original docomo-logo (it maybe caused by european boot.bin??)

    Thank you.

    Now siyah kernel support both international i9100 and SC-02C in a single kernel image.Just download the latest version from gokhanmoral's web site and add a script in /system/etc/init.d/ gps will work for SC-02C.

    Code:
    #!/sbin/busybox sh
    echo 16 > /proc/sys/kernel/rom_feature_set
    sleep 5
    chown root.system /sys/class/sec/gps/GPS_PWR_EN/value
    chmod 664 /sys/class/sec/gps/GPS_PWR_EN/value
    A CWM flashable script:

    Flash CM10 rom,then kernel build by me,then ics compass fix,that's all.
    You may wipe cache and data。
    If you use sc-02c stock rom,you should remove assert script in CM10 rom(Open the zip, go to META-INF/com/google/android/update-sctipt. Remove the top 6 lines with the assert then repack).
    @wjchen0: Did you flash CM10 rom cook for I9100 version first, or just flash CM10 kernel that you built?
    I want to enjoy JB as soon as posible... Can't wait for Docomo support :((

    Thank you very much for your reply, currently my phone use

    I am going to root my phone to use root explorer.
    so as your instruction, i have to download xxxOMKL4xxx.tar file and use root explorer to copy the files as you mentioned to the phone right?
    Many Thanks

    You should rename sensors.*.so(sorry I forgot the name) to sensors.GT-i9100.so or sensors.default.so first,then just replace the files.
    Here is siyah kernel and speedmod kernel for sc-02c ics compiled by me, GPS works fine.I hope this can help.
