Because if you flash an incomplete rom (missing an image of a partition that changed location) you can end up with an inoperative phone.

You need a firm understanding of the partition table layout of the GS2 (including the variations of the specific models) and how the various image files relate to the partitions.

hi to all,

I would like to root my japanese sc-o2c `cause I have a lot of problems with the HSDPA signal. I think that re-flash the baseband is right to fix this issue.

Can anyone post a clear and easy guide to root this device please?

I`m a newbe with android.

thanks
[Galaxy S II General] R3wt3d:

ok finally uploaded

this can be flashed with odin3 (mmcblk0p9)

Can you tell me how to flash a dd rip? can I do it with odin3?
[Galaxy S II General] nakagusukumike:
Thanks to YOU:

did you use heimdall to flash?
[Galaxy S II General] nakagusukumike:
i simply dd'd the .img file to my block device. yanked the battery and rebooted.

yellow triangle gone,

gps works,

tv works,

still have root.
[Galaxy S II General] nakagusukumike:
the 300MB factoryfs.img file, What is it? Stock Docomo with root? Or just BONE stock docomo, out of the box?
[Galaxy S II General] devilangellus:
sorry can understand what you did.

Can you explain me step by step ?

sorry ^^;
[Galaxy S II General] nakagusukumike:
me?

[Galaxy S II General] devilangellus:
yeah can you explain me what you did for got everything work with root?

i just rooted my sc2 and lost one seg, would like everything working on it ^^;
[Galaxy S II General] nakagusukumike:
download the stockkernel.zip (mmcblk0p5) file above.

put it somewhere on your phone.

install a terminal on your phone

in the terminal:

su -

cd /mnt/sdcard/

ls

(make sure you see your mmcblk0p5.img file)

if you do:

dd if=./mmcblk0p5.img of=/dev/block/mmcblk0p5

once that completes PULL YOUR BATTERY

reboot the phone

no more yellow triangle and your TV/GPS should work.
[Galaxy S II General] R3wt3d:
system

that is /system with su installed.

1) Installed rooted kernel from that jp blog I posted before

2) Ripped the /system with dd

3) uploaded to a stock SC-02C after using ext4_tools (that's the image I uploaded) with Odin3

4) got root on stock SC-02C with su (need to install Superuser.apk)

5) ripped mmcblk0p5 to sdcard

now I'm going to get back to my rooted SC-02C to stock kernel...

Can you tell me how to do it with dd? I'm using Win7. Can I do it with adb?

Hey yes,,u can give me beer...I'm living near u :P
[Galaxy S II General] R3wt3d:
Thanks will do try it now !
[Galaxy S II General] nakagusukumike:
see my previous post. install a terminal on your phone and peck that **** out on your phone. don't mess with ODIN or ADB when doing dd stuff on the phone..

Cheers!!! You in Okinawa!??
[Galaxy S II General] devilangellus:
cool will try as soon as i can :)
[Galaxy S II General] evildave_666:
This works, back to stock kernel, no triangle, rooted, 1-seg works.

Thanks much

Going to stay this way until there's a stable CM7 build.
[Galaxy S II General] R3wt3d:
just did..and worked fine!

yeah I'm near u ;)

[Galaxy S II General] nakagusukumike:
tonight, I will be messing around with this and trying to get stock kernel, working GPS, working TV and docomo baseband but all on a custom ROM. I'll let you guys know how it goes.

I have a feeling the "docomo" account on the phone is spying on us and being a tattle tale for enabling tethering. Either way, I don't want to run the docomo ROM.
[Galaxy S II General] nakagusukumike:
what file do you need? PM me an email address.
[Galaxy S II General] nakagusukumike:
FOR ALL YOU GUYS WHO ARE BONE STOCK DOCOMO

Stock Docomo SC02C --> Stock with root, stock kernel, working TV and GPS

steps:

1. install the root kernel (the one that breaks your TV and GPS) via ODIN3 1.85

http://xdaforums.com/showthread.php?t=1103399

Instructions - ODIN (long)

- Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!

- Unzip the attached CF-Root-xxx-vX.X.zip

- (USB) Disconnect your phone from your computer

- Start ODIN

- Click the PDA button, and select CF-Root-xxx-vX.X.tar

- Put your phone in download mode

- (USB) Connect the phone to your computer

- Make sure repartition is NOT checked

- Click the START button

- Wait for the phone to reboot

2. install terminal application on your phone

3. download mmcblk0p5 and put it on your sdcard on your phone

https://rapidshare.com/files/3881593431/stockkernel.zip (Thanks R3wt3d!)

4. reimage your kernel back to stock

in a terminal:

su -
cd /mnt/sdcard/
dd if=./mmcblk0p5.img of=/dev/block/mmcblk0p5

verify that it wrote the digits (it will say it wrote some numbers)

yank battery

reboot

5. no more yellow triangle, and everything works but you still have root.
[Galaxy S II General] onikage:
@robotsapiens

regarding the first paragraph of your reply..obviously your SC-02C is still unlocked after rooting and installing litening ROM. have you changed your kernel or are you still on stock kernel?

because i am afraid if i go to docomo and have my SC-02C unlocked and afterwards i will root and install a rom it gets locked again. my 3150 yen would go to waste.:(
[Galaxy S II General] Kachi21:
Can you send/receive SMS and MMS?

Use 3G and Wifi?

And what about career mail (xxx@softbank.ne.jp)

Thanks in advance.
[Galaxy S II General] evildave_666:
You do not need to root to flash a new baseband.
[Galaxy S II General] soundpassion:
Than what can i do?
[Galaxy S II General] onikage:
read this thread made by nakagusukumike. anyway, read first before you do anything to your device. dont forget to back up. specially the efs folder.

cheers!:)
[Galaxy S II General] Kachi21:
Sorry to ask a noob question again, but does installing the mms.apk file to use Softbank simcard mean that we can no longer use the stock sms/mms application?

I'm about to order a Galaxy S2 from Hong Kong, and I really want to have the "chatting" display (like the iPhone) when exchanging SMS/MMS (what the stock sms/mms application does)...

Thank you in advance.
[Galaxy S II General] nakagusukumike:
Sorry I've been away so long. I've been busy building a house and procreating.

So!

I've installed Cyanogenmod 7 on my SC02C. Follow the standard install instructions and it will work but you'll have crap for signal again, just like any other ROM.

No (practically) signal and no GPS/TV Drivers.

I don't have the latest and greatest files so I just stripped the baseband out of the old .tar that I made and flashed JUST the SC02C baseband over the default CM7 install. Works like a champ. Everything works great except of course GPS/TV drivers because those are in the kernel.....

Here's a link if anyone wants to do this and just live with no GPS/TV for a while:

http://blacklinux.com/pages/public/computers/android/SC02C/SC02C_ModemOnlyODIN_v1.tar

And here's the original modem/kernel combo:

http://blacklinux.com/pages/public/computers/android/SC02C/SC02C_ModemandKernelOnlyODIN_v1.tar

I have not yet tried flashing this old as crap kernel on top of CM7 which is 2.3.7. I'm not sure what, if any, issues there would be. I'm about to try though.....

Cheers!

*EDIT* flashed the old SC02C kernel and it doesn't boot. Not too surprising considering the android version mismatch. Pretty far off on releases. I guess I'll just rock this with no GPS for a while. Man it feels like back in the old days of the Vibrant.
[Galaxy S II General] evildave_666:
Considered trying the SC-02C Siyah kernel? Its supposed to work on either stock or CM roms.
[Galaxy S II General] nakagusukumike:
oh snap, didn't even see that till just now. Looks like it would work. I'll check it out when I get home from work! Thanks man! Been outta the game too long to keep up on all this. :o
[Galaxy S II General] zaphod777:
let us know how it goes. I might be interested in trying CM7. I am running DlevROM2 right now but might be interested in switching.
[Galaxy S II General] nakagusukumike:
Thanks! I just straight flashed the kernel over a running CM7 install, and it booted right up on reset. GPS works. Theoretically so does the TV but I can't get the APK to load. HUGE Thanks to gokhanmoral!

not the best GPS signal, but I was surrounded by at least 30cm thick rebar reinforced concrete walls :-)
[Galaxy S II General] evildave_666:
I'd also think about pushing the OMKJ4 baseband onto there. GPS locks crazy-fast with it.
[Galaxy S II General] nakagusukumike:
i know this is old as hell, but I got a less than 3 second lock outdoor with it just now. I'll rock it. I'm lazy.:)
[Galaxy S II General] elfwine:
I am currently using GS2 for my Softbank black sim card, quite happy with the phone. My only concern is the wifi issue and 3g slow connection. For the wifi, I'm having problem with lose connection and for the 3, it's quite slow compare to my iphone 3gs. I don't know if it's apn setting's problem or what, if anyone resolve these issues, please let me know.
[Galaxy S II General] elfwine:
When I installed CWM 4, I got this voice app. It's quite useful sometimes though for sure Siri is much better. well, hats off goes to samsung as they did it first, apple knew that samsung have some patents with regards to it, that's why they bought Siri. but the thing is, Samsung started that concept and didn't much improve it and apple made the same features in a different implementation and better way so people will think Samsung is copying apple's feature again.

Dcomo SC-02C baseband OMKJ4 need root

My Docomo SC-02C has OMKJ4 baseband and I need to root it then unlock it to use with other carriers. Any recommendation and help is much appreciated. Thanks
[Galaxy S II General] robotsapiens:
At this point I think I have done all the possible changes with this phone. I tried different kernels, modems and ROMs and the unlock never "left" the phone. But for precaution, while the NTT staff is unlocking you can ask her what is the unlocking code, just in case you have the same problem (they agreed to give me...)

Right now I am using SC02COMKG5 as modem, Siyah1.5NTT as kernel and Litening 6.1 as ROM, and I am feeling like upgrading everything...
[Galaxy S II General] davidspwy:
mine one is MKJ4, Siyah2.1.1NTT and DlevRom2 3.1,smooth and less bug,recommended~!
[Galaxy S II General] anti-doom:
How can I get the Siyah2.1NTT kernel and DlevRom2 3.1 ROM? thanks
[Galaxy S II General] espionage:
I'm wondering if anyone can help here. I have a Japanese friend with the Galaxy S2 (Optus locked in Australia) who would like to convert it into a stock Japanese handset for regional and language support. Currently she is using ATOK free trial which is about to expire soon. She is not able to purchase a full version of this app as she is not in the related region. I had to do a lot of googling to get a trial version from some site which I installed for her. So, I have a few questions:

- is it possible to flash this phone (aussy version) with the NTT firmware?

- if flash is possible would it lock the handset to NTT network?

- are there any custom roms out there with Japanese language support for this version of S2?

I'd really appreciate if someone could help me.
[Galaxy S II General] evildave_666:
Cyanogenmod has the japanese menus and the like.

You may be going a little overboard though. All you should need to do is root the phone and install market enabler to be able to purchase the full atok.
[Galaxy S II General] onikage:
yey! good to hear that! thanks friend!:)

Dlevrom2 v3. 1: multiupload.com/PMRNX8S82Q

-Sorry I'm a new user so i can't post outside links... But i just found these less than 5 minutes ago so you'll be fine. Just add the http www part.

Note: the baseband built into Dlevrom2 has pisspoor reception so flash the stock baseband OMKJ4 after you flash the rom and you'll be swimming in awesomeness... Just be aware that although gps works the north and south poles are inverted so you basically need to hold you're phone upside down when using navigation. ENJOY!

EDIT: one more thing.. If you can't find the stock baseband send me your email and I'll email it to you.
[Galaxy S II General] zaphod777:
How did you install CM7? I just installed the zip from Recovery but it just hangs on the the Docomo screen.
[Galaxy S II General] espionage:
thanks mate. so in a nutshell market enabler would bypass the android market check based on your region, right?

alternatively, would CM7 rom give a full Japanese menu and look? BTW, my friend would prefer a full native Japanese interface.
[Galaxy S II General] zaphod777:
Guys also be very careful when using CM7 for the first time. By default it chooses mopera as the default APN!

On a side note I got it running on mine you have to flash it twice when installing it before rebooting.

But then I went and goofed trying to install the Google Apps. I tried through recovery but they didn't show up so I tried doing it through ROM Manager and letting it install recovery (I figured worst case I would just have to re-install the kernel) big mistake. Now I am stuck at the docomo screen and can't get into Recovery. I can get into download mode so I am just downloading the stock images now. Hopefully reflashing those will get me back and I can start over again :(

If any one has any tips regarding getting the GApps on there that would be great
[Galaxy S II General] zaphod777:
Well I guess after installing the gApps add-on it only allows you to download them from the market it doesn't have them already installed. I'm back up and running now. CM7 looks pretty nice!

how to unlock samsung galaxy s2 sc-02c

hi guys im new android user i have sgs2 sc-02c version 2.3.3 how to unlock this phone? i need a complete tutorial because i dont know anything about android thank you...
[Galaxy S II General] evildave_666:
Take it to the Docomo shop along with 3150 yen and an ID.
[Galaxy S II General] mr_villagomez:
Bring your phone to a docomo shop and ask them to unlock it for you... It should cost about 3150yen... If you want to root it, google odin 3 v. 1.8.5. Download siyah kernel ntt v2. 1.1 and use the pda option in odin to flash the kernel to your phone. To prepare your phone for flashing power it down, then press and hold power, volume down and the center button at the same time. When you see the menu to put it in download mode press power up. After that plug your phone to your pc and turn on odin then flash the kernel. When the flash is complete(should only take a few seconds) your phone will be rooted. I provided the link to the kernel on this topic page 80 if im not mistaken. Google odin3 1.8.5 its not hard to find... If you can't find it pm me your email and I'll send it to you. It's a small file
[Galaxy S II General] johnfrozen:
Hi guys,

it looks like we have active SC-02C users in Japan.

I`m new android user(1st with sc-02c, previous iphone)

I`m having problem with my sc-02c when i tried to unlock it using odin v1.85.

maybe i flashed it with the wrong kernel file, after i flashed it won`t turned on,also it won`t charge up, it just stuck on the docomo screen with the triangle yellow mark.

I tried to reflash with the stock root (link by intratech) but when i do so, odin just failed. odin says success when i flashed only the kernel but the phone still didn`t boot up. now i have a lot of binary counts..

what should i do...
[Galaxy S II General] zaphod777:
Pull the battery and then put it back in. Then hold volume up and home button and turn on. From recovery do a factory reset and wipe the cache and dalvek cache.

What did you try and install?
[Galaxy S II General] johnfrozen:
Thank you zaphod777,

I'll try it later because now my phone is out of battery,

Well,at 1st i try to root the phone,later that i realise this phone is different compared to overseas galaxy s2..

I can't charge my phone as well,it says "charging.jpg draw failed" in green text ,is it normal?
[Galaxy S II General] zaphod777:
It sounds it is missing the charging jpg. I would recommend you re-flash the default ROM and get back to a factory state. The SC-02C is a little different from the regular international version so you need to take some extra precautions when installing a ROM or custom kernel on it.
[Galaxy S II General] johnfrozen:
Owh.,okay,

How should i do that?do you have any link or referrer?

FYI:i already tried to re-flash ROM (Ntt Docomo provided by intratech),using odin v1.85,following all the instructions,but it just failed after several minutes.

Then i don't know what else i should do.

Thank you Bro.,

I'm using Siyah v2 (for ntt docomo), and DlevROM2 3.0

Although Google maps works (albeit with upside down compass) I can't get My Tracks, Endomondo, Sports Tracker to work, as they all force close at some point.

Is this more likely to be a ROM issue, rather than kernel issue? Does anyone else have the same problem? Can someone test this please? I'll ask in the ROM thread too.

Please people, can someone answer me? :(

I'm currently using a Softbank black simcard.

If I buy an unlocked GT-I9100 (from Hong Kong), put my Softbank simcard in it, and change the APN :

1. Would I be able to send/receive SMS, MMS, and S!mail by using the stock messaging app?

I really would like to have the same kind of "chatting" display for the messages as the iPhone by using the GT-I9100 stock messaging app (with all SMS, MMS and S!mail centralized in the latter)

2. Would I be able to use 3G correctly?

In advance, thank you very much.

[Galaxy S II General] rushter:
I had many issues with my battery when I first got mine. Turned out that my FOMA card was bad. Set your device to 3G only also as that tend to make it bounce back and forth and drain a lot of power. Switch the 3G first and see what that does and ignore the display readout saying the display is using all of your battery, of course it is, it is the largest power draw but it is probably not the culprit. Hope this advice helps you.

If after you've done the above and are still having issues, complain, complain, complain at the docomo store about the FOMA card and ask them to swap it out for you.

Guys, i downloaded Shadowgun and i can't say that it runs 100% smooth. So i tried to check with "CPU spy" and found out that my cpu only runs at about 500MHZ whenever i play games. (wind up knight, blood and glory, shadowgun - which are pretty 3D intensive games)

Shouldn't the CPU be running at 1200MHZ almost all the time during running games like these? Help? :D

EDIT: Eternal Legacy and Asphalt6 running at 1200mhz. Still wonder why Shadowgun runs on 500mhz average. Can anyone with shadowgun confirm this?

hello evildave_666 (or anyone else who would like to help as these instructions are super simple but missing a few steps) - quick question or two...

What are the settings on Odin (just the part about what is checked and then pulling in the OMKJ4_factoryfs_root.zip file via the PDA button) supposed to be? like what it says here at this website?

http://newtechjp.net/android-hack/98-how-to-root-your-samsung-galaxy-s2-ntt-docomo-japan.html

Will this still have all of my apps and what-not left on the phone or do I have to restore everything?

Sorry about being a pest - was so much easier on my OG Droid back in the day - hehe.

Thanks

So here are the steps I took -

1 - Put my device in debug mode

2 - Started up ODIN - Both Auto-reboot and F. Reset time are checked

3 - Connected my SGS2 - get a good connection - no prob

4 - Do I need to do the PIT thing or just the PDA button and add the file there.

5 - Not sure what I am supposed to pull from the OMKJ4_factoryfs_root.zip file - there are like 3 files in there - the factoryfs_root.tar.md5, the modem.tar.md5 and the zImage.tar.md5 file

And then hit Start I suppose but I am getting stuck trying to guess what to do here.
[Galaxy S II General] evildave_666:
No PIT (never PIT unless you are going between an SC-02C stock image and something not specifically for SC-02C, and not even then in most cases)

PDA - factoryfs_root.tar.md5 should be all that you need. The modem should already have the same version from the previous update to OMKJ4.

See this if you need more details (in japanese).
