Sorry to jump into a long thread but hoping you guys may have some advice...

Friend has the SC-02C and was wondering what custom kernels (preferably with busybox and recovery included) are available. Have heard mentions of the Siyah kernel but not really sure what that all entails. Reason being is that I have a CWM .ZIP that does the job under those above conditions that I use for the Epic 4G Touch. If I can recreate the same conditions on the Docomo GS2 it should be just a matter of flashing the same .ZIP and you're on the way. Can also do Odin one clicks if folks are interested and I can get the rest of what I need - mainly the stock .tar and a .PIT file.

Also does anyone know a good place to try and find one for sale? Hoping there might be some up for grabs, particularly around Okinawa if possible. At the worst it would be for dev work... at the best it would be a phone for visits and (if can be unlocked) for use here in the States. Thanks in advance!
[Galaxy S II General] evildave_666:
Siyah is the path of least resistance because it has the proper support for the SC-02C's unique bits and comes pre-rooted with CWM.

Would not recommend repartitioning an SC-02C unless you REALLY know what you're doing. Cross the streams with an I9100 and therein lies madness. (The partitions are laid out in the same order but sizes are different and you run into issues reloading SC-02C stock roms unless you had the foresight to extract and save a copy of the original PIT on the phone)

Plenty of places to find used SC-02C and you'll find more and more of them as next June approaches and people who got the first round of them rush to upgrade to whatever shiny new subsidy handset is available then. I'm waiting it out too, but will probably keep my SC-02C as a backup.

Current prices range from just under 20,000 up to 26,000 yen for reliable units depending on how much of the original kit (box, cables, etc.) is there and how pristine it is. Online shops like musubi.net and ecotan are a good place to start but I ended up picking a used one for my wife for 20,000 at a Sofmap brick and mortar shop.
[Galaxy S II General] garwynn:
Thanks - Sounds like Siyah (guessing user's name for the builder, like Agat for our pre-rooted CWM version) will do the job. So as long as someone has the .PIT file it wouldn't be hard to make a pure stock one-click root, one that would get the job done without triggering the yellow triangle and great for noobs like my friend.

Saw one place listing them for $250, sounds about right based on what you mentioned. Know the cables are interchangeable as I used the E4GT one to plug a SC-02C into my PC. I actually took apart the factoryfs.img to see what I could possibly install or port over for my wife... problem is the SC-02C image is bigger than ours and without some of the other components it freezes the phone on boot. I might try stripping out more to fit it into our 512MB image... but afraid that still may not be enough to really get it to work.

Thanks for the info!
[Galaxy S II General] garwynn:
Hope I'm not bugging anyone by asking questions...

Took a good look through the thread - is it correct that there still isn't a true restore .tar for OMLPL yet? (including recovery.bin, sbl.bin, boot.bin, etc.)

Would anyone be interested in such a build? Think nakagusukumike had the right steps last year - just was missing a step or two. The hardest part IMO is boot.bin - get that resolved and I think the rest is fairly easy to accomplish.
[Galaxy S II General] DenisGuy:
So? Do you like your new kernel?

Battery life on Siyah 4.1.4 is ridiculous. I get 7 hours on 1 charge and I don't even use 3G data. I'm back at 3.5.2 and I'm getting around 12 hours.
[Galaxy S II General] SimmoF:
There is a tar available. Use CheckFus or visit sammobile.com/firmware

There are guides on how to dump boot.bin and sbl.bin from a working phone.

No recovery .img on the gs2. Its in the zImage
[Galaxy S II General] garwynn:
Thanks - already got the OMLPL tar so that covered all but the 3 bins mentioned, data.img and the pit file.

Sbl was already posted on an earlier post so I got that.

Would just need someone to at least dump the boot.bin and .PIT file.

As for recovery.bin I asked Entropy512 about this as well.

Oddly enough the Epic 4G Touch (Sprint's GS2) does have one - always thought it was Odin since our recovery is similarly "baked" in the kernel. It is the same size as zImage....

Anyhow, if anyone would want a stock rooted OMLPL that doesn't trigger the triangle please let me know. Need someone to do a few tasks and then I can get the rest together from here.
[Galaxy S II General] SimmoF:
Use MobileOdin by chainfire.

It can flash the system and it roots it too.

[Galaxy S II General] garwynn:
Thanks - guess if I do it I'll share it with others; beyond that doesn't seem like there's much interest or need for one. (One click)
[Galaxy S II General] evildave_666:
Isn't really a need for a restore that includes boot/sbl. Docomo has never updated them on OTA updates. (There was a newer SBL on new devices starting around end of 2011 but older devices never received it in OTA) Even if you mistakenly update SBL there's a backup automatically saved in the alternate partition.
[Galaxy S II General] zaphod777:
I am going to be messing around with the stock ROM and Siyah kernel a bit but I remember someone had a ZIP file that would enable tethering on a stock ROM. Can someone point me to that ZIP file?
[Galaxy S II General] SimmoF:
That was my tweaker zip. :D

It's available on my Dropbox in the Galaxy S2 folder.

It's called sc-02c_tweaker_xxxxxx.zip

It will delete the Docomo garbage though. ie launcher, widgets and other crap.

I have removed the kernel and Samsung Japanese keypad from it.

Now it just contains:

Modem:	SC-02C OMLPL + RIL

Apps:	SuperSU
Busybox
Google Play 3.8.17 MultiDPI + Compatability Fix

Tweaks:	Set NTP server (jp.pool.ntp.org)
Free tethering (tether_dun_required=0)
NTT GPS & compass fix
Facebook ContactsProvider database patch (is_restricted=0)
Black camera viewfinder fix for the Docomo rom
Docomo bloatware deletion
[Galaxy S II General] zaphod777:
Can you link to your drop box folder?
[Galaxy S II General] SimmoF:
LOL, forgot that part. Here it is.
[Galaxy S II General] DenisGuy:
Ok, guys and girls, I have another issue. Hopefully someone here has the answer.

Listening to music/videos on my headphones, I noticed that the volume levels are almost all the same. Out of 15 notches, only 3 actually do something.

Also, when I try to use 3rd party apps, like Volume+, they have absolutely no effect.

I'm on Siyah 3.5.2 and on the latest CM10 nightly. I also gave Siyah 4.1.5 a shot, but it didn't fix it. I don't wanna go back to cm9... should I?

Can anybody help?
[Galaxy S II General] SimmoF:
Get extweaks on the market. It controls siyah. There is a volume boost setting.
[Galaxy S II General] DenisGuy:
This really helps. Thank you.

There are still only 4 volume notches that work, though, only the 4 first.... the other ones don't work. Does anybody know why/what to do?
[Galaxy S II General] wendac:
which version of siyah kernel is best for cm10 nightly ??

i just installed cm10 and feel it kinda laggy and battery not good
[Galaxy S II General] dhaub:
Just a quick question for japanese language speakers.

Can anyone confirm whether the sc02c supports the

Same cellular frequencies as the i9100?

I tried to check the docomo Site but

It's all in japanese!

Thanks guys.
[Galaxy S II General] rushter:
Are you using the international version for SGS2?

I was wondering which one of the nightly's would be the best.

I am still on cm9 and have actually been loving it with siyah 3.5.2.

Also, I have been using CM9 this week and really do love it. I still think battery life is an issue. Today, while riding the train, my battery percentage dropped from like 40% down to 22%. So I decided to drain my battery as far as it would go. It got as low as 8% then jumped back up to 13 percent.

Maybe, for some odd reason, after you install a new Rom, this should be one of the steps.

Just saying.
[Galaxy S II General] evildave_666:
No, it is band I/II/VI on WCDMA.
[Galaxy S II General] zaphod777:
Check out volume control v2 I don't know why you have this issue though.
[Galaxy S II General] vipsavior:
Try running the battery calibration App simple and it works. I had the same problem that you had with false battery readings. After you charge your battery to 100% the app will clear your old battery stats.
[Galaxy S II General] dhaub:
Thanks mate,

Any chance band VI (800mhz) is compatible with band V (850)?

I had a look on a wiki page and it appears that band V crosses over the same frequency range

as band VI, would this perhaps be dependent whether a perspective band V carrier's

utilised frequencies fall within the range of my phones compatible band VI?
[Galaxy S II General] wendac:
Anyone use cm 10? Got quite often freeze and have to reboot. Is that normal??
[Galaxy S II General] SimmoF:
For me yes. Especially when using Chrome browser.
[Galaxy S II General] evildave_666:
No.
[Galaxy S II General] DenisGuy:
Same here: I've completely stopped using Chrome. I'm on Dolphin and it works a lot better. But I didn't have to reboot because of the freezes. That might be because of the memory leak (known issue with CM10.)
[Galaxy S II General] SimmoF:
Sprint uses 800mhz ESMR. You'd have to check if it's compatible.
[Galaxy S II General] SimmoF:
For anyone who is interested, I am working on a "custom rom".

It's custom in the sense that I tool a stable CM9 rom, and I'm modding it for our hardware.

I did not compile it or anything.

It includes all necessary fixes, tweaks, Google Apps, Kernel configurators and a few other goodies.

But mostly it's an untouched CM9. Ready to go with only 1 zip file.

Let me know if there's something you'd like included, or have any ideas, or would like to test it once I have it ready.
[Galaxy S II General] rushter:
Obviously, no overbloating it, but I have been using Google Now for a couple of days with CM9.1 and it appears to be working just fine. It's an installable zip - the thread is here. I used the offline M7 version. Check out this thread.

http://xdaforums.com/showthread.php?t=1747224
[Galaxy S II General] dhaub:
Wow that sounds excellent SimmoF, I'd love to test your rom. FYI I'm currently running CM9 with siyah 3.5.2 and the following patches: gapps, S99FixNTTGPS_cwm, ics-compass-fix_cwm.zip and signed_cm9-build.prop. I originally came from SC02COMLPL so I've retained the modem from that rom.

Do you know by any chance how to extract the SC02COMLPL unrooted kernal so I can run pure stock after applying root patches?
[Galaxy S II General] SimmoF:
What is signed_cm9-build.prop?

I'm at the final stages of building it.

I am making scripts that take a base rom and do stuff to it, such as tweaks and other things (not just adding files).

I'll let you know when there is something to test, not long but.
[Galaxy S II General] dhaub:
Not sure exactly what signed_cm9-build.prop is, but i'm pretty sure it is needed to flash cm9 because from memory coming from SC02COMLPL unless I flash signed_cm9-build.prop first CWM won't let me flash CM9.

I got the advice from here:

http://xdaforums.com/showpost.php?p=29575185&postcount=1659

If you wanna take a look at it you can get a copy from my Dropbox:

https://dl.dropbox.com/u/20242742/phones/sg2/files for recovery flashing/signed_cm9-build.prop.zip

Any news on the SC02COMLPL kernel?
[Galaxy S II General] SimmoF:
Oh, I know what you mean, I will be removing that issue.

The kernel is available inside the official tar file.

Get the official tar here.

Warning, it's 500mb.

---------- Post added at 12:13 AM ---------- Previous post was at 12:04 AM ----------

OK, so the rom is done. It's currently uploading.

I will post the feature list soon.

It should flash directly on top of a preinstalled cm9.

But it will need a dalvik-cache and cache wipe, or you will have problems.

Also I need some people to test using a full wipe, preferably as the primary rom.
[Galaxy S II General] SimmoF:
Ok, the first buildof my rom is ready, I hope some of you can try it.

The download is available here.

--------------------------------
| Simmo's CyanogenMod 9 for SC-02C |
--------------------------------

I hope you enjoy this rom. I made it for everyone on the XDA SC-02C thread.

I recommend running the Fast Dormancy Toggle app and disabling FD.
Turning off FD saves power for me. You may uninstall the app after.

Please wipe cache and dalvik-cache, even if flashing this rom over the top of itself.
If you get weird/random app crashes, just try wiping the caches again.

Features:

Siyah Kernel 4.1.5
ExTweaks

Extra System Apps
AdAway
Android Terminal
BetterBatteryStats
Gmail
Google Apps
Google Chrome
Google Drive
Google Japanese IME
Google Maps
Google Plus
Google Reader
Google Street View
Google Translate
Polaris Office
Samsung Japanese IME
SuperSU
YouTube

Extra Data Apps
Adobe Flash Player
Fast Dormancy Toggle

Tweaks
CM10 Boot Animation
ContactsStorage Mod (to allow Facebook Contacts in Address Book)
Free Docomo Tethering (It works for me, don't complain if it doesn't for you)
Google Play (DPI + Compatability mod)
GPS Faster Fix (NTP patch)
SC-02C Inverted Compass Fix
SC-02C OMLPL Modem and RIL files
SP-Mode APN

You probably installed an incompatable kernel.

Goto settings->about and type what info is shown in kernel in this thread.
[Galaxy S II General] rushter:
Did you use CM 9.0 or 9.1?
[Galaxy S II General] SimmoF:
9.1 stable.
[Galaxy S II General] rushter:
So just install it over my 9.1, wipe cache and dalvik and I should be good? Nothing else needs to be done?
[Galaxy S II General] rushter:
Why do all of the other ROM builders say to install Gapps separately?

Are you gonna get into trouble for that? LOL?
[Galaxy S II General] rushter:
OK installed and I will run it for a bit and see if everything is ok. For those trying this it acts like nothing is happening at first. Just let it go and it will install fine. Don't get worried if the screen does not do anything while installing. I also ran the FD thing just to see how that works out. Not sure why you (SimmoF) say to delete it after I run it but I still left it there and ran it and rebooted.

"I used to be a stock ROM kinda guy, now I am flashing all kinds of crap to my phone. LOL."

As the Japanese say, Gambatte.

BTW - SimmoF or Zaphod777 - wife has the older Toshiba REGZA T-01C - anyone know of a way to root that one?

And @zaphod777 we are going to Hawaii next week. I unlocked my phone a while back, I think it is still unlocked but now I have no way to check because of CM9, did you say that you could use a regular AT&T GoPhone sim and just change the APN to get data to work on it? If so please let me know. Thanks.

I think you'll find that it's just cyanogenmod. Because Google asked them not to include it. Everyone else just includes it cos they don't care.

SimmoF's new ROM - try it out - easy to install

Installed and running. Took off of charger - battery dropped 7% in about 30 minutes but that doesn't mean anything yet. Real test will be tomorrow when I take it out on the road, so to speak.

Seems stable for now. Not sure that the 4.1.5 of Siyah will be ok and if that messes with the battery too much, I will revert to 3.5.2.

Gonna install Google Now - now - lol.
[Galaxy S II General] SimmoF:
My friend has this phone. I couldn't get it rooted. I researched and If you haven't done the ota updates you can root. Using ginger root or the other similar app.

---------- Post added at 02:15 AM ---------- Previous post was at 02:07 AM ----------

One way to save power is to go to accounts and settings for Google and uncheck the features you don't need. Such as Google reader auto sync and perhaps instant upload etc. You can run the included BetterBatteryStats to see what's causing your drain. I can help with that. Just tell me what app(s) are at the top of partial/kernel wake locks.
[Galaxy S II General] rushter:
OK BBS says the following on partial wakelocks -

NetworkLocationLocator - com.google.android.apps.maps.Maps

AudioOut_1

Kernel wakelocks -

PowerManagerService

wlan_rx_wake

l2_hsic

Hope this helps.
[Galaxy S II General] SimmoF:
Really easy.

PowerManagerService = Total of all partial wake locks. This can't be helped.

wlan_rx_wake = Wifi is turned on. If your not connected to a wifi network turn it off

l2_hsic = switching between wifi/3g and jumping cell towers and switching 3d to hsdpa. High when your reception sucks. Or if you are in an izakaya basement or on the subway etc. This can't be helped.

AudioOut_1 = system sounds, click, screen lock, sms tone etc. This doesn't actually vause a battery drain and this counter will go up each time a sound is made, even if the screen is on. It doesn't actually cause much drain even if it's high. Unless it's is super high, but you may have been listening to music or playing a game or movie? Ignore it.

and last.....

NetworkLocationLocator. This is the main issue I have with....... Google Now.

It keeps checking my location and drains my power so freaking fast.

Things to try.

1. Open google maps. Goto settings.

2. Checl location reporting so that report from this device is highlighted. Uncheck report, then uncheck location reporting (do not update your location).

3. Uncheck "Enable location sharing"

4. Uncheck "Enable Location History"

5. Uncheck "Automatic checkins"

Now if you still have an issue get an app called Autorun Manager or a similar app. it's not free but you can find it if you look. ;)

Goto google maps and disabl all checkboxes under it. (Google maps will still work when you open it)

If you STILL have a problem, I'm sorry, you will have to disable Google Now.

I didn't include it in my rom because of the battery issues. I would get about 9% drain per hour with it. As opposed to the average 2-4% I would get otherwise.

As good as it looks, it is always checking your location to update the cards. And since I never actually use it, I could not justify having it switched on. BUT having it intalled and switched off still gives you the nice google search options etc.

You will have to decide if you want Google Now or bettery battery life.

Good luck.
[Galaxy S II General] SimmoF:
Ok, the new build is ready and uploaded.

sp-mode mail with push is working 100%. And hopefully area mail too.

The apps are already bundled with the rom.

The new download folder is here.

Oh and please remember to wipe caches as this one has an updated framework.jar patch.

And it won't work if you don't.
[Galaxy S II General] dhaub:
Flashed your rom an hour ago, so far so good. The only inconvenience I've noticed is the lack of a file manager; I'll keep you informed if I notice anything else.

Still trying to figure out how to flash the stock unrooted comlpl kernal. I've extracted the zimage from the stock odin package, repackaged it as a .tar for flashing with Odin but Odin never seems to get beyond beginning zimage, without actually writing anything (see screenshot).

I might explain that the only reason I'm interested in reverting to stock kernel (from rooted stock rom) is so that I can get the official OTA updates and add a bigger list of apns to the small number included with the stock rom without having to manually input settings. Any suggestions?

Thanks guys.
[Galaxy S II General] SimmoF:
The reason your tar won't flash is because its not the right format. I had this issue too. There is a particular command line argument you need to get it to work. I'll post the command tomorrow.

I didn't include a file manager app because everyone has their own preference. And I can't find a free one with root ability worth including that matched the holo theme.
[Galaxy S II General] evildave_666:
I'll give this rom a shot on my wife's SC-02C tonight. Will probably be a better match than running CM10 nightlies and dealing with the mobile data disconnect bugs.

I assume the intent is to keep this as a relatively stable release and not nightly it?
[Galaxy S II General] dhaub:
Cheers for the headsup. I managed to flash the stock kernel using Chainfires amazing Mobile Odin. The things so useful it allows you to open up the stock image and choose what you want to flash. Worked as described!
[Galaxy S II General] SimmoF:
I could nightly it. I like nightlies. What do you think?

[Galaxy S II General] rushter:
I went back to my previous build. The battery drain due to Siyah 4.1.5, in my opinion.

Restored my Siyah 3.5.2 and battery life is much much better, even with Google Now.

My setup is pretty much the same as what you had designed but main difference being the kernel.

4.1.5 - drains battery at about 10% per hour.

3.5.2 - drains battery at about 3-4% per hour.

Curious to see how others do without Google Now installed.

I was able to use one last year , look up what APN to use. Cm10 probably already has it though. I did need to change the type from MMS to internet or something similar. But I could only get an edge connection which was good enough. I just paid for the one month unlimited everything including data but the data isn't for a smart phone it is for a flip phone. That is why you need to change the APN.

I have no idea if this still works or not though.
