[Q] foreplay with SC-02B (Japan/Docomo) : how to go further ?

[bebert218]

Hello people !

Since I'm living in Tokyo, I'm the happy owner of a Galaxy S, but unfortunately it doesn't seem to be exactly the same like the other devices.
Anyway, since 2 days ago, I had some fun (and cold sweat also) trying to root it, unbloat it, etc... Some difficulties and questions left without answers, so if anyone has a guess, please be my guest !

My phone as I got it :
SC-02B, with OMJJ1 firmware (Froyo 2.2)

1) Rooting
The easiest thing ever.
The SuperOneClick pack did a wonderful job.
http://forum.xda-developers.com/showthread.php?t=803682

2) Getting a "safe" firmware
Just in case anything would go wrong, I wanted to be able to flash back to an official firmware.
The ones from this post work without any problem so far.
http://forum.xda-developers.com/showpost.php?p=10558974&postcount=134

However, problem 1 : I couldn't get Heimdall flash my device. Since I'm mainly working on Linux and OSX, that would have been of a great help.
But the "handshaking with Loke" step is always failing...
Actually, I even though I had bricked the phone, since I was stucked with a black screen (1PC and 1GSM in orange) and it took me ages to figure out how to get rid of that.
Solution : get myself a Win 7 computer at office and use Odin. No problem so far with this one.

Problem 2 :after flashing with the official update, I get complains in the recovery mode (when unpacking the apps I think), saying that /dev/block/mmcblk0p3 cannot be mounted, because it does not exist.
After searching on japanese sites, it seems that there is a 3rd partition in addition to the one for /sdcard and /data that is used (as far as I know, only for that) by an app called DioDict (japanese / english dictionary).
Not that this is a great loss, but I don't know where and why this 3rd partition was deleted. I tried to restore one, but after a while I just gave up, since I don't have any dump of the data that was there anyway...
Could anybody confirm/infirm this ???


3) Recovery 2e
Since I wanted to test to other roms, I needed to get back to the recovery 2e.
I gave a try to CF-root, which included that also.
http://forum.xda-developers.com/showthread.php?t=788108
Once again, Odin was the only one that could do the job, Heimdall still ignores me.

Problem : the update is successfully done, but for a reason I ignore, I lose my SIM card in the process.
Flashing back an official ROM makes it available again, but CF-root won't allow me to phone in Japan.
How did you people handle that ? Unfortunately I couldn't afford staying too long without a working phone, so I didn't investigate much further, but did other people have the same kind of problem ?

Conclusion :
As of now, I have a rooted device, and am pretty happy with it.
However, I wish I could give a try to the nice work I've seen around (CyanogenMod on Galaxy S seemed very yummy), while still being able to use my SIM card here.
Any feedback is welcome !

I haven't played around that much with DioDict to tell you right away how to solve this, but maybe there's some answer getting the first firmware:

SC02BOMJJ1 (10/10/13) :
http://fus.samsungmobile.com/Phone_...2BDCMJJ1_SC02BOMJJ1_SC02BOMJJ1_OM_DCM.zip.enc
BINARY_ENCRYPT_STRING 1662317

 

[bebert218]

thanks a lot for this link ! just a question, where did you guys find them ??? the site itself seems very dummy
but as far as I could read on japanese threads, that seems to be some prefab settings
in my case, that third partition has been deleted, so I think I would have to recreate again beforehand.
as for the "how", I must confess I don't know... I' had somehow succeeded in running parted to create one, but for a reason I ignore couldn't assign it to the block

 

[bebert218]

I could install a Cyanogen Beta3 today, and though everything is alright, still got no 3G.
SIM card is not recognized, and it seems impossible to input the appropriate APN information. Could it be that the modem embedded in the SC-02B is different from the mainstream one ?

EDIT : seems that indeed the SC-02B has a different modem. At least the firmware has a different size, hence the need of a different PIT file when you flash from an "international" ROM.
I'm starting to wonder whether I'll see the end of it someday >_<

things that seem to work

Now that we have the capability to recover after we trash our ROM what can we do.
Super Oneclick root - works
Z4Mod "because we all have the need for speed" -works after you use titanium backup to remove some of the bloat-ware from /system
Z4Control works if you use Z4Mod to patch the kernel and convert /data to ext2 first.
The UOTKitchen will work to change the battery icon and other status bar icons if after you have completed these steps http://forum.xda-developers.com/showpost.php?p=9318973&postcount=1290 you extract the framework-res.apk from the resulting zip file and use adb to push the new framework-res.apk to /system/framework/framework-res.apk followed by an adb reboot recovery command before you do anything with the phone. From the recovery menu wipe cache and then reboot now. If you don't do this last step it could lead to having to reflash the factory firmware happened to me about 6 times this weekend. DO NOT TRY THIS IF YOU HAVEN'T CLEARED ENOUGH SPACE ON /SYSTEM BECAUSE IT WILL KILL YOUR PHONE!!!!!

 

[shikigamild]

For all those who want a pit file, here I leave you a custom pit file created for the sc-02b.

I must make this clear, this PIT file was made for those who flashed their devices with a rom for some other galaxy s version and want to reflash their devices back to the original SC02BOMJJ1 rom. I cannot ensure you it will be useful or that it will work for anything else.
Also, when using this PIT file with odin, be sure to check the "Re-partition".

 

[bebert218]

@shikigamild :
is this PIT file the same that came from komugi.net ?
at the same time, could you tell me how you got the stock rom file links please ?

@dejanet :
so you say that with the Z4mod you have a fully working device ?
has anyone tried the CF-root package ? after applying it I lost my SIM card, so I wonder if you experimented the same kind of inconvenient there

 

[dejanet]

Oh yes went through all of the fun of trying the various kernels everyone leaves you with sim not recognized.

Aaarghh,that sucks donkey balls...
Guess that means we won't get any, custom rom any time soon will we?

 

[bnr32jason]

I'm new to all this stuff, so apologies for the noob questions.

I rooted my SC-02B using the tool in this thread. I was able to install and use the Barnacle Wi-Fi tethering app from the market, so I know it was a successful root. Now when I go to install and use Titanium Backup from the market, it tells me I don't have root access or don't have BusyBox installed. When I go to install BusyBox from the market it shows my phone as being rooted, but when I tap install it gives me a failed message saying my phone isn't NAND unlocked.

How do I do that? Once I get that problem solved, what are the next steps for installing the Z4Mod?

 

[bebert218]

So far I've never installed BusyBox through the market. Just install it with Titanium and it should work fine (click the "Problem ?" button).
Then, I suggest that before doing ANYTHING involving a custom initramfs (like ClockWorkMod), you dump somewhere your mmcblk0p3 partition, in case you want to restore your phone exactly to the same state you got it.
If your not that paranoi, you can skip this part, but as I wrote myself a dozen times here, I forgot it and would be interested also ^^

 

[bnr32jason]

Ok, thank you for the info. Does Z4Mod cause any problems with this phone? I read in dejanet's signature that the lagfix seems to cause problems. Z4Mod is the lagfix he's talking about right?

z4mod is just a rooting app. There's no lagfix. He's probably referring to OCLF which is made by the same developer. It's obsolete now, so do not use it.

About the rom problem, can't you just flash the modem from a Docomo rom after installing the custom rom?

 

[trojan111]

No, z4root is only for rooting, but z4mod is a lagfix application. As far as i know, it will convert your phone system to ext2. However, i scare it will affect the DioDict application in SC-02B, so i haven't tried it yet.

 

[bebert218]

Trojan,if you fear losing diodict,you can still dump your mmcblk0p3 partition.
It is the one containing diodict data.
I would actually be very grateful for an upload of that one (^-^)/

Opps. Didn't realise there are two apps with similar names.

Still, wouldn't suggest it. EXT2 is unstable.

 

[trojan111]

Hi, bebert218. Actually, i am a noob, i don't know how to do it. Can you tell me how to view the partitions in the internal memory? I suppose DioDict application contains a database file somewhere in the internal memory, but i don't know where and what the file name is. Appreciate if you could give me a hand on it. Thanks.

Custom Kernel and Roms

From reading through the forums it seems custom roms present issues with the either the sim card or modem on the sc-02b. Are custom kernels causing issues as well on this phone?

 

[dejanet]

Yes it is the kernel that causes the problem. I think a couple of us have tried them all.

disappointing Other than rooting and using Galaxy tuner to do some tweaks there isn't really much else to do. At least the upgrade to omka5 showed much improvement from 2.2
