They are, in fact, not the same.

Wonder which block device it is. Maybe just infer based on what the resulting file sizes are and which one is 7 or 16 MBish.

I bought mine two days ago, and only this morning did I realized that there is a retractable antenna that is used for the SEG TV. Have you tried deploying it?

yeah, there is an antenna. 1seg App won't even attempt to tune. It's totally different behavior in the app after flashing a kernel with root.



... I've got a feeling the baseband is /dev/block/mmcblk0p8. I'm about to revert to a friends...

the gs2 is my first android and I would like to root it but after reading your posts it is freaking me out.
How do I rip my system and make a total baseband back up? is the basic back up app enough?
I was thinking of using lite ning rom, do you think it would be safe for the SC02?
Thanks

i'll have an answer for you in an hour or two on if you can install a root kernel and keep your GPS.

As of right now, what I've gathered is: you install a root kernel, you loose your TV for sure.

Install a full rom and loose your base band and your GPS is borked too.

My buddy is coming over my house right now and I'm gonna try to dump his good binaries and inject them into my phone. I'll let you know how it goes...

I was literally minutes away from rooting when I saw this thread. Thanks for your insight -- hopefully you get this figured out. I don't care about the TV, but I'd love to return to using my root required apps and custom roms without breaking everything else.

I'm 100% stock still -- I can't manipulate and hack away code myself, but I can follow directions and type out command line stuff if you want me to try and get something from the phone.

This will really all become moot the first time there's a carrier update and we can download/extract the files from off the Kies server. Then we'll have good PDA/Baseband files so we can always go back barring a total brick.

hopefully I can get this GPS thing worked out. Just waiting on anyone with a working GPS on an SC02C to send me dd dumps of their 2 through 6 partitions...

Code:
su -
dd if=/dev/block/mmcblk0p2 of=/mnt/sdcard/mmcblk0p2.img
dd if=/dev/block/mmcblk0p3 of=/mnt/sdcard/mmcblk0p3.img
dd if=/dev/block/mmcblk0p4 of=/mnt/sdcard/mmcblk0p4.img
dd if=/dev/block/mmcblk0p5 of=/mnt/sdcard/mmcblk0p5.img
dd if=/dev/block/mmcblk0p6 of=/mnt/sdcard/mmcblk0p6.img

    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 :((

    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.
