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.

Got it now, factory standard firmware is:

PDA: SC02COMKF2
Phone: SC02COMKF2
CSC: SC02CDCMKF2

(Yes, those SC02C prefixes ARE correct, not GTI9100)

I'll see if I can extract original firmware from Kies tonight when I get home.

DoCoMo is bundling a 1GB microSD, and selling the charger seperately (I have 3 other micro-usb-charging phones so no big deal).

Oh, and I think the Palette stuff must have been removed at the last minute, I can't find any trace of it.

Kies firmware info:
SC02COMKF2/SC02CDCMKF2/SC02COMKF2/SC02COMKF2
ProductCode - SGH-N033LKNDCM

Yes, these ARE different than the usual format, I know.

They ARE correct though, direct cut & paste out of my Kies registry keys.

(DCM obviously DoCoMo and SC-02C is the japanese-market name for the handset, Galaxy S was SC-02B)

Actually its NOT. I later found out how to activate it (there's an app called "home switcher" or something which lets you toggle back and forth between Palette and TW4). Its just as nasty as the promo videos make it out to be.

On other fronts, I rooted today. There don't appear to be any firmware images available on kies for the SC-02C so I had to take a leap of faith and try to root without a backup kernel to go back to. CF-Root-SGS2_XX_OXA_KF2-v4.0-CWM4.zip did work though. CF-Root kernel seems to lack support for the one-seg TV though.

The big downer - the nv_data.bin hashes for unlock keys are using a non-zero salt, which means an unlock will be hard to come by without foregoing handset subsidies.

I guess I keep my Galaxy Ace for use on overseas trips for the time being.

so.....

If I get the docomo SGS II can I put whatever ROMs on the phone that are available for vanilla USA SGS II?

The whole reason I have a vibrant here in Japan, instead of the docomo SGS, is because there are no ROMs available for the docomo phone (that I know of).

Please advise. I might go get one this week...

I'm so happy. DoCoMo called at 1845 to tell me I could pick up my SC-02c. Of-course by the time I got to the shop they were closed so I'm going to have to burn half a days leave today and try to beat the crowd. It was a surprise because when I pre-ordered they told me all of the first order were already sold so I guess they either got a bigger shipment than expected or there were some cancellations. I'm guessing that since CF-Root worked we will probably get a crack at some custom ROM's unlike the SC-02b.

Its probably obvious but I'd be very wary about flashing the baseband image on an SC-02C in Odin since DoCoMo are obviously doing something different in there as evidenced by the differences in unlock. CSC/PDA will probably be OK though.

Sorry I forgot to mention the one-seg not working. I never use it so no big loss for me.

Any particular reason you used KE8 rather than KF2 to match the rest of the firmware already on the handset?

My GPS seems to work OK. I don't think it would be affected, since my guess is that'd go through the baseband.

3G totally inoperative then? That's bad, why I tried to put the warning up earlier about being careful nothing touches baseband.

I need to fix my signature the kernel in my sig is for my SC-02B not the SC-02C I did use the KF2 Kernel for rooting my Galaxy S II.

    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:
    https://dl-web.dropbox.com/s/g47a9r0dz14w0wj/S99FixNTTGPS.zip

    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
    2.3.6,
    DXLP7
    2.6.35.7-I9100XWKK5-CL754841root@Dell144#2
    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.
