Root Docomo Samsung Galaxy S 2 Easiest way

So I asked for instructions for rooting my SGS2 and this is what I got -

For me, it was not enough. I am too detail oriented sometimes and needed something a bit more specific so I went ahead and searched everywhere on this thread (it's the only one with the Docomo Samsung Galaxy S II) and couldn't find some simple answers to make sure that I don't brick my phone. So here are the exact steps I took.

Please note - I am not responsible for anything you do to your phone. Attempt this at your own risk. You must have a completely stock Docomo Samsung Galaxy S 2 running the KJ4 release that was just released by Docomo.

What you need:

Samsung Galaxy S2, a Windows PC, a USB data cable, Odin Downloader (Download Here - http://newtechjp.net/Download/Odin3-v1-1.85.zip ), the factoryfs_root file (Download Here - http://www.megaupload.com/?d=8XKTJUWX this is a large file and the download speed is very slow so get this first)

1 -Put device in USB debugging mode: Settings -> Applications -> Development -> USB debugging

2 - Reboot your device into download mode - Turn the device off, then power it on again by pressing and holding VolumeDown + Home + Power simultaneously.

3 - Start ODIN Downloader

4 - Connect the device to your computer via USB. Wait a few seconds, the ODIN screen should show you that a device is now connected. Ensure that the checkboxes next to “Auto reboot” and “F. Reset Time” and leave everything else as is. We'll continue with this in a moment.

5 - When we set all of this up we downloaded that large factoryfs_root.zip or whatever it was called from megauploads. Locate that file and uncompress it somewhere and remember the location. Once unzipped, there will be three files in there - we are only concerned with the factoryfs_root.tar.md5 file the modem and zImage fle are not needed at all. Just remember where you put them.

6 - Go back to ODIN and now Press the “PDA” button, and select the “factoryfs_root” file you extracted a few minutes ago. Once selected, the little checkbox to the left of PDA is marked and the file location is listed to the right.

7 - Press “Start”. ODIN you should now be flashing the kernel, and the device should reboot.

8 - DO Not Remove the cable and Wait until the device is rebooted.

9 - You're Done!

10 - To verify, go into your apps tray and look for the program called "Superuser"

Many thanks to evildave_666 and all the others that make rooting and owning Androids great fun.

thanks for this...

one more thing.can i unroot my sc-02c for warranty purposes?or can i get back to stock rom after i flashed a custom rom?
[Galaxy S II General] evildave_666:
Yes, unless you've repartitioned you can trivially get back to stock by flashing the OMKG5 or OMKJ4 image via odin.
[Galaxy S II General] takoyaki17:
thanks thanks thanks...
[Galaxy S II General] mr_villagomez:
Anyone have a solution to the reversed poles on GPS when running roms other than stock? Stock rom for me with Siyah 2.2i NTT runs fine but all other roms with any kernel have reversed north and south when using google maps. I use GPS a lot so this is the only thing keeping my rom experience short of awesome. Thanks.
[Galaxy S II General] davidspwy:
After i restored back to the Stock Rom and rooted my sc-02c, the following messages appear on the screen in the recovery mode.

Just letting you know SC02COMKL1 v2.3.6 is out now.

You can download it with CheckfusDownloader from fus.nanzen.se

Just make sure you check [Test Mode]

It appears to have a few new icons and apps, including what appears to be an early earthquake warning app.

I am using the SiyahKernel 2.2i from the gokhanmoral website

Sorry, can't post links yet. New member.

Enjoy.

Edit: The WiFi is not working with this kernel, I have posted the stock kernel which you should then reflash after rooting with Siyah. If the su binary is missing, make sure to install it before you flash the stock kernel.

Edit: This version includes GTalk with Video chat!
[Galaxy S II General] davidspwy:
Thanks. Upgraded and Rooted...but the above questions remain.:confused:
[Galaxy S II General] zaphod777:
Those of you who have SIM unlocked your phone, did you put it back to stock before you brought it into the docomo shop? I am going to get mine unlocked on Sunday.
[Galaxy S II General] evildave_666:
I didn't bother. Even took a Titanium backup right in front of them before handing it over.
[Galaxy S II General] mr_villagomez:
No takers? Am I the only one with this problem?

On a different note I just wanna give everyone a heads up that ICS 4.0.1 is available through garnet miui 2.11.26. Just be sure to install an earlier version of miui first and don't do a data wipe and you shouldn't experience any bootloops. I'm running it now with Siyah 2.4 NTT and the black ice theme and im enjoying the few extra perks.

Just remember its just a framework merge so there's not much extra stuff but i found it runs smoother than 1.11.25 and the stock launcher supports scrolling widgets which is something I always use. You can also modify the carrier label in the notification bar to say anything you set it to.

Sorry I can't post direct links cause I'm a new user but if you just google galnet miui 2.11.26 you won't miss it. Enjoy!
[Galaxy S II General] SlazsH:
Btw guys, how do you ask for an "unlock" at the shop? They call it "unlock" too? And do they ask for any requirements? And how much...
[Galaxy S II General] onikage:
that would be "shimu rokku kaijo (シムロック解除）" or you can just show them you have a different sim card that you want to use on your docomo gs2. if you don’t have any contract with docomo, you can bring your alien card as identification and don’t forget the 3150 yen fee for this. hth.:)
[Galaxy S II General] evildave_666:
OMKL2 dropped on testmode last night.
[Galaxy S II General] SlazsH:
thanks, sir! i have a contract as of now. the same 3150yen fee still applies? would they charge me cash for that, or add that to my next bill?

By the way, whenever i update the FW, root or flash a custom ROM/FW, will i lose the unlock?

---------- Post added at 11:19 AM ---------- Previous post was at 10:59 AM ----------

I'm going to the Philippines this Sunday, will have my gs2 unlocked today.

Did you use a prepaid Smart SIM?
[Galaxy S II General] onikage:
I don't have a contract with docomo so i wouldn't know if you can get discounted..but i think the fee would still be 3150. i think.:confused: as for me, since i didn't have any contract they charged me cash for unlocking. as for you, you might have an option to pay cash directly or let them add the fee on your next bill.

regarding losing your unlocked state when changing FW's and ROM's..I asked robotsapiens about this and he said that it stayed unlock. you can check it from my previous posts in this thread.:D
[Galaxy S II General] evildave_666:
Unlock is permanent. Its on a cash & carry basis only.

I was using my normal smart buddy prepaid. Incidentally they made a change some months ago and you don't need to switch to the smart apn for data to work.
[Galaxy S II General] SlazsH:
The SIMcard you used was a special prepaid SIM that had data activated, or all newer prepaid cards now have data activated on them? Sorry for the ignorance, i am not really updated with the latest carrier news in the Phil.

If that is the case, could i just buy a prepaid SIMcard once i reach NAIA and just pop it into the unlocked gs2? :D
[Galaxy S II General] evildave_666:
All smart prepaids have had data preactivated on them for at least a year now. The new thing is that the APN doesn't matter (this is on smart only, globe/sun you still need to set up manually). On my last holiday I didn't even notice that I'd not changed from the docomo one until 4 or 5 days later.

If you use a 3G on/off widget that uses changing the APN to something invalid as the switch it won't work that way now on smart - you need to actually turn data on/off in settings to accomplish it.

Yes, me2.

I wrongly flashed an old i9100 bootloader and forgot to dump my SC-02C bootloader before.

I have tried to extract all versions of stock firmware but cannot find any sbl.bin... ...

Does any one can help us? thanks

[Galaxy S II General] zaphod777:
Hey guys FYI I got my SC-02C running on ATT prepaid SIM but it only works with EDGE.

I got the $50 unlimited voice, text, and data for a month. The data is not supposed to work unless you add a specific data plan for a smart phone. However since my imei is not in their database as a smartphone since I didn't buy it from them they think it is a flip phone and i am able to use data. It is slow but works.

How about the Wifi after you rooted, SC02COMKL3?

My wifi stop working after i tried, can you share me the file?

Thx in advance.

After rooted,you should restore the stock kernel.

You can download it with CheckfusDownloader,then extract zimage out,finally flash it back.

No one has the stock docomo logo?

Please kindly let me know how to get your bootloader dump.

This is a raw dd dump of the partition, I don't know if there's anything else that needs to be done with it to make it suitable for odin flashing.
[Galaxy S II General] clement.km:
Can you share the dd dump of 0p3 to us?

I tried to restore the 0p2 it still booted with i9100 logo..

Thanks much

Clement
[Galaxy S II General] evildave_666:
My 0p3 (SBL2) is and always has been blank (all zeroes). Docomo have never updated bootloader since release.
[Galaxy S II General] clement.km:
ok, thanks. it might be something wrong during the dd restore. let me try again.

Yes it works finally, i made some mistakes is the first trial!

Docomo logo is back
[Galaxy S II General] davidspwy:
How to do this?Would you mind to tell me the step here?Thanks~
[Galaxy S II General] clement.km:
Yes. Please see page 7 of this thread. There is example of backup and restore dd dump by mobile terminal.

Be careful do not have wrong spelling which will crash up your system if the 0p2 flashed into block other than bootloader

Thanks a lot. It works.

I suspect we may see an official OMKL3 release tonight or tomorrow.

Omkl3?released.im using.
[Galaxy S II General] evildave_666:
An official non-testmode OTA release.

Actually the maintenance on their OTA server may not be a new-release thing, might be related to the problems DoCoMo are having with their account database.
[Galaxy S II General] SlazsH:
Hi guys. I am currently in the Philippines for a vacation and installed samsung kies on my pc here and shows that "Your Device Does Not Support Software Upgrading via Kies" (I had my SC-02C unlocked prior to leaving Japan)

Do i need to change my CSC in order to get the OMKL3 update here? any ideas?

Also says "no update available" on the OTA too.

Why doesn't kies support software upgrading all of a sudden on my phone?

Could it be caused by the unlock or just by the region and CSC?

Stock rom and stock kernel here 2.3.5
[Galaxy S II General] evildave_666:
OMKJ4 is the latest that has been officially released. This is not unusual.

The update server is currently down because Docomo has had a serious account database glitch related to their smartphone service.

I'm off to Visayas tomorrow myself.

battery cover of SC-02C and I9100??they are different.cant swap to use. i have both 2 phones.
[Galaxy S II General] minaprefect:
Ok, so this is my first time posting.

I just upgraded my kernel and ROM and everything is working except the one damn thing I want to work.

I'm currently using:

baseband; SC02COMKG5

kernel version; 2.0.35.14-Siyah-v2.3-ntt+gm@ubuntu

build number;

DlevRom2 3.1 kl4 edition

I'm trying to use Tasker to create a program that will automatically turn on and off my GPS, and get

> "For Android 2.3+, Google have made changes such that it is no longer

> possible for an app to change GPS without user-interaction. If you

> wish to continue using Tasker's GPS action you may wish to consider

> installing a modified ROM such as Cyanogen which does not have

> Google's restriction."

and it's killing me, since I lack the knowledge of what will work on this model.

What should I install instead?
[Galaxy S II General] zaphod777:
Well delev is a modified Samsung rom so it may not have it included. But you may also need to install the logging add-on for the kernel.

You can install CyanogenMod the same way you did with delev where you replaced the kernel and baseband afterwards. But I found CyanogenMod to be a bit buggier.
[Galaxy S II General] evildave_666:
So then I9100, SC-02C and M250 all have different ones? 3 different types then...
[Galaxy S II General] khoaak01:
I've got OMKL4 (rooted) already. It's good but there are a problem. When i play game Feild Runner, it jump out home screen suddenly. I think the reason is Kernel. Anyone has Kernel for this version? Plzzzzzzzz.
[Galaxy S II General] mr_villagomez:
Check gokhanmoral.com and download the latest NTT version kernel. I believe it's. 2.6.1... TAR is for flashing through Odin and ZIP is for flashing through Clockworkmod. Enjoy!
[Galaxy S II General] mr_villagomez:
Anyone try the ICS 4.0.3? I believe Docomo uses NITZ but some people are reporting calls and data working regardless. Would try it myself if I didnt use my phone for work. If anyone gets data and calls I'll try it out right away.
[Galaxy S II General] khoaak01:
Wifi doesn't work in 2.6.1 ver
[Galaxy S II General] mr_villagomez:
I was running it for a few days until last night and wifi works...I had a similar problem as yours with one of the older kernels that no one else seemed to have... you might want to try one of the older kernels. The one I personally thought was pretty good was 2.2.1...

Off topic but if you're willing to delve into alpha ICS 4.0.3 I'm running the airborne360 alpha 13 and so far so good... I get data and text messages and wifi works... I haven't tested calling yet for the Mic but this thing loads web pages blazing fast. Its almost like the entire internet has been downloaded to my phone for OFFLINE VIEWING!
[Galaxy S II General] SlazsH:
Guys, what is the latest official firmware for the sc-02c? Im still currently abroad and OTA updates still show "no update available".

OMKJ4 here
[Galaxy S II General] evildave_666:
About Back Covers

Facts:

* I9100 and M250 covers are different (well documented on xda-dev)

* I9100 and SC-02C covers are different (personally verified now that I finally was able to physically examine the I9100 extended battery kit)

The remaining question:

Are the M250 and SC-02C covers the same or different?

If they're the same this is probably good for us because there's a ton of korean ebay vendors selling the korean kits and they're in better supply than the I9100 version.

If they're different it means we're 99.9% sure to never get a properly-fitting extended battery pack.
[Galaxy S II General] evildave_666:
You are running the official release.

THERE ARE NO ADDITIONAL NEW FEATURES IN GINGERBREAD VERSIONS ABOVE 2.3.5 THAT CONCERN THE GALAXY S II (Except possibly for the M250 models).

Is there a particular bug that's affecting you or are you just compulsive to be running the latest load?
[Galaxy S II General] SlazsH:
I just wanted to know if OTA updates would be functional for me, now that i am abroad and using a different sim card - because when i plug my phone into kies, it says my sc-02c is not able to check for FW updates. (Not sure if it is because of my region and csc or there was a problem with the update server.) That is why i was asking what the latest official fw is, for me to know if i need to change the csc for the new update to show via OTA/kies - or if 2.3.5 is still the latest official fw for sc-02c.
[Galaxy S II General] zaphod777:
I would think ota updates should work as long as you haven't removed any of the built in apps using root.
[Galaxy S II General] evildave_666:
You really want to use Titanium Backup Pro's freeze function to do that instead. It preserves the OTA update functionality.
[Galaxy S II General] zaphod777:
Yup, I learned that one the hard way. Although I'm running a rom anyway but I have a stock backup for whenever they release ICS.
[Galaxy S II General] Sharpen3d:
I think this was referenced somewhere in the thread, but I have a copy of the One-Seg tv app (backed up via Titanium) but cannot restore it whatsoever. Any advice/download links to a working apk?

[Galaxy S II General] SimmoF:
I have been having issues with Siyah kernel with OMKLx.I recommend that you try SakuraMilk's kernel. It has working One-seg, GPS and Wi-fi. There is also an app called TweakGS2 that he makes that allows you to tweak the kernel. github.com/sakuramilk/sc02c_wiki/wiki

There are 4 kernels available, a Docomo one, an AOSP one and a duel boot once but this requires you to repartition your phone and one for the enwly leaked ICS rom. Use the Docomo one if you have a stock rom or the AOSP one if you use CyanogenMod or MIUI.

The TweakGS2 app is under the tools section.

another thing sir...i have a sc-02 unlocked.if i root my phone,will it stay unlocked?

can i use all the rom in galaxy s2 custom roms?
[Galaxy S II General] zaphod777:
It will stay unlocked. I reverted to stock with root when I got my phone unlocked just to be on the safe side and later restored my ROM'd backup and the unlock stayed. I did ask the Docomo guy to write down the unlock code just in case I needed it but I didn't.
[Galaxy S II General] takoyaki17:
thank you man....did someone here tried the ICS kernel and ROM?

any reviews about it?
[Galaxy S II General] clement.km:
Hope docomo will release official ICS tomorrow soon otherwise international kernel and modem may not support GPS and TV etc
[Galaxy S II General] zaphod777:
was there a rumor that they would? I was under the impression that we are at least a few months away. Plus I am sure an ICS build would show up on the testing server a week or so before they do roll it out.

---------- Post added at 03:41 PM ---------- Previous post was at 03:20 PM ----------

Anyone else get "no firmware found" when trying to use Check Fus? I wonder if we are about to get an update soon ... It would be pretty sweet if it was ICS but I am not going to get too excited.
[Galaxy S II General] SimmoF:
I'm not sure, looks like they pulled OMKL4 a week ago, I was thinking an update is imminent too. Docomo seem to push updates fairly regularly, so we might even get an ICS beta too. Fingers crossed.

thanks again...

1.)can i use rom manager to install CWM,i have root access but don't have CWM.

2.)can i flash baseband and kernel on CWM?

3.)what's the binary count all about?

i tried sakuramilk kernel flash via odin,after the reboot...ntt docomo with exclamation inside yellow triangle.after that it just power off.

4.)do ihave to flash an ics rom first,then flash the sakuramilk kernel?

5.)what baseband do i have to flash?

sorry for a bunch of noob question...i just want to know all about galaxy sc-02c.

i'm loving this beast.

Hi,

Did you find out about M250 and SC-02C? As I remember the pattern on the cover is totally different, M250 pattern is same as i9100, while SC-02C is smoother.

However, I did not try to fit M250 cover into SC-02C.
