[Galaxy S II General] jdfly82:
We are finally moving back to the US in a couple of months, and before I use trial and error, do you guys have any recommendations for modems that work properly on AT&T? I haven't been back since I was on stock Gingerbread and I had the proper modem for that. I don't have one that works with ICS or JB, the SC-02C modem will only pick up the Edge network.
[Galaxy S II General] zaphod777:
Gingerbread Modems will work on ICS. Which one did you use before?
[Galaxy S II General] jdfly82:
Sweet, I think it was KL7, but I downloaded a few of the K series modems so that I can try them all.

BTW thanks for the advice on dealing with DOCOMO. Incredibly easy to change out my phone and now I have a brand new one for going back to the states. Hopefully I can wait until the next nexus is announced before upgrading.
[Galaxy S II General] dhaub:
Anyone know how to change the docomo boot logo to stock samsung?

I tried to follow this guide:

http://xdaforums.com/showthread.php?p=14993096#post14993096

but Odin gets stuck at "param.lfs" and doesn't budge.

I took the param.lfs from the latest australian sg2 stock rom and placed it in a tar file.

any pointers?

[Galaxy S II General] evildave_666:
Thought you just had to flash an I9100 SBL.
[Galaxy S II General] SimmoF:
evildave is right, flash the galaxy s2 sbl.

This one is compatable with the USB jig, so I recommend it. Just flash with Odin.

---------- Post added at 09:09 PM ---------- Previous post was at 08:55 PM ----------

OK, the first thing I recommend you try is install a stock Samsung rom.

Then install the Docomo modem and RIL if you used an international ROM.

Then use RF Band selection code *#2263# and make sure that bands are enabled that AT&T use.

It should be set to Automatic.

Bands available that I can see are

WCDMA 2100/1900/800

GSM 850 900

DCS 1800

PCS 1900

According to the AT&T info on Wikipedia

Frequencies used on the AT&T Network Frequency
850 MHz	GSM/GPRS/EDGE	2G
1900 MHz	GSM/GPRS/EDGE	2G
850 MHz	UMTS/HSPA	3G
1900 MHz	UMTS/HSPA	3G
700 MHz	LTE	4G
1700/2100 MHz(AWS)	LTE	4G

So the GSM 850 matches as well at the 1900 3G.

But you're out of luck with the 850Mhz 3G, which is sad to say as the lower the frequency, the better the signal penetration.

So you're phone should work on AT&T @ 1900MHz 3G.

Help much?

OKay, a noob here. The Wi-Fi on my Gs2 ntt docomo refuses to turn on, i need to reflash, current specs

Model SC-02

can anyone guide me as to how and what files i need.

P.S. the links n the first page are not working any more.

Help much appreciated
[Galaxy S II General] SimmoF:
Use checkfusdownloader to get the latest

ROM. Then flash with Odin.

There are lots of guides for both apps.
[Galaxy S II General] dhaub:
Hey mate,

If you intend to stay on stock docomo firmware it will be easy

to flash to stock firmware.

First things,

Factory reset phone!!!!

grab CheckfusDownloader (google checkfus, grab the gui version).

and Odin 1.85 (again google).

Open up, Checkfus and on the standard tab, input your relevant cell details, android>sc02c>Japan,

then do checkfirmware it should indicate the latest firmware to be SC02COMPLPL. If all is well

click download and wait.

When it is done, you may get two files SC02COMLPL***********.enc

and a SC02COMLPL************.zip, extract the zip and

hopefully you should now have the relevant file: SC02COMLPL_SC02CDCMLPL_SC02COMLPL_HOME.tar.md5.

Now you need to put your phone into download mode. To do this power-off, and now simultaneously press

volume-down, homebutton and power button till it goes into 'download-mode'. Do volume up (continue) and once

in the "Downloading..." screen connect USB to computer.

Now fire up odin make sure you have a yellow square there that says something like "0:[COM10],

make sure the only boxes ticked are "auto reboot" and "f.reset time", now select pda and point to

SC02COMLPL_SC02CDCMLPL_SC02COMLPL_HOME.tar.md5. When you're

ready press start, and wait till it says finish, your phone will restart and you can now d/c usb and close Odin.

Enjoy!
[Galaxy S II General] rukhi:
Thanks for elaborate reply, ill try this method and bug the page again if i run into trouble :)

[Galaxy S II General] rushter:
Lol. Sorry for the long rant.... I deleted it.

UPDATE: I went into recovery manually and restored a backup that I did on the 19th of August. It appears that has given me my superuser back as I can open TiBackup (my test program to make sure root is there).

The only issue that I had during the restore was at the very end it said ".android_secure.img not found. Skipping restore of /sdcard/.android_secure" not sure if that will be an issue.

I backed this up with the Siyah 4.1RC1 Kernel I think... one of the 4.1 versions anyways. Then I went back to 3.5.2 because of the battery life of 4 being bad.

Maybe this time will be a charm or I may just go to the next 4.....? kernel.

Stay tuned... I would still like to know about the above issues that I had and suggestions.
[Galaxy S II General] DenisGuy:
Hey...

I know this is an old post, but it doesn't work for me. I'm on Siyah kernel + CM9. Do I need to use the Galaxy S unlocker while on stock? What am I doing wrong here? I've tried all the unlock tricks, still SIM locked.

BTW I'm not in Japan so I have no other "legitimate" way to unlock my phone.

Any help would be very appreciated.

EDIT: The SIM Unlock (helroz's Galaxy S Unlock) actually works but it doesn't stick: after I reboot, the files are back to lock. What am I doing wrong here?

2ND EDIT: In Busybox, I'm getting "more than one copy of Busybox was found". I uninstall busybox, uninstall the app, re-download the app, reinstall the app, reboot, and the message reappears. I guess I did something wrong when flashing/rooting? Can anyone help?

3RD EDIT: I'm sure at 75% that the issue comes from Siyah's kernel. Basically Busybox is installed at 3 different places on my phone and every time I try to uninstall one of the locations, it comes back after a reboot. I fixed the permissions (in both CWM and Rom Manager) to no avail. If you have any other ideas please let me know.
[Galaxy S II General] rushter:
How are you checking that the unlock is not there anymore? I unlocked mine a while ago and even after doing a full wipe it is still there.

Update: Helroz has stated on his play store listing that some ROM's lock at reboot. Hope that helps.

---------- Post added at 02:29 PM ---------- Previous post was at 02:13 PM ----------

To all here in this thread, sorry about my rant last night. I have gone back into my Siyah 3.5.2 because all of the 4.1 versions kill my battery worse than the 3.5.2.

I am still having a significant battery drop that I can't pinpoint. BBS not withstanding.

I am thinking that one of the recent updates to an app is causing the issue.

I am slowly uninstalling every app and reinstalling them one by one.
[Galaxy S II General] DenisGuy:
@rushter: what's the process using most of your battery?

@rushter: When I reboot my phone it goes to the "SIM unlock code required" screen. However immediately after I use Helroz's unlocker, I can get on the network. It stays that way until I reboot. And when I reboot it goes back to the "code required" screen, then I use Helroz's unlocker again, and can access my network again.
[Galaxy S II General] SimmoF:
.android_secure.img is when you move apps to the sdcard, if the image is gone, you will need to unintall/reinstall these apps.

You'll know which ones they are cos they won't work when you start them.

I recommend you install SuperSU instead of SuperUser. Just download from the play store and flash on top.

I was having issues with BBS too, this appears to have fixed it.

Siyah 3.5.2 does have better battery life from my testing.

My recommendation.

Write down all the apps you use. Reinstall CM9. Install 3.5.2ntt over the top. Wipe cache/data.

Reinstall apps, install SuperSU, install BBS.

Test it. Oh and flash the OMLPL modem + ril.

Oh, and if your problem is persisting over all of this effort, it's likely been an app that you keep restoring.

---------- Post added 7th September 2012 at 12:09 AM ---------- Previous post was 6th September 2012 at 11:46 PM ----------

Well, since I had issues with the original SD card I replaced it with an 8gb one. But I haven't installed any apps on it.

I am running SuperSU - check

Siyah 3.5.2 - check

reinstall CM9? - negative - I haven't installed it a first time yet. I have this small issue with worrying about the brickbug.

Our 190+ pages of posts makes it difficult to find all instructions to make all work well in one spot. So researching this takes a bit longer.

Once I get CM9 on I will go through my list of apps and install them one by one vice a big titanium backup restore.
[Galaxy S II General] DenisGuy:
Um... yeah... can anybody help me understand why my changes don't stick? Please?

Thanks for the idea, but I tried that the first few times was in the states. All I was ever able to connect to was Edge. I successfully flashed a modem that worked once, so I will just try that one again when I get back.
[Galaxy S II General] dhaub:
Hey mate,

I'm gonna detail the whole process of what I did to hopefully

rectify your problem. I might add firstly that busybox is included

in siyah kernal so forget about bothering to install it.

**THIS ASSUMES YOU HAVE WIN7/XP IF YOU HAVE MAC YOU MIGHT WANT TO TRY HEIMEDALL INSTEAD OF ODIN.

1. BACK TO STOCK (apologies but xda won't let me paste my post link):

**REMOVE SIM CARD!!

Factory reset phone!!!!

grab CheckfusDownloader (google checkfus, grab the gui version).

and Odin 1.85 (again google).

Open up, Checkfus and on the standard tab, input your relevant cell details, android>sc02c>Japan,

then do checkfirmware it should indicate the latest firmware to be SC02COMPLPL. If all is well

click download and wait.

When it is done, you may get two files SC02COMLPL***********.enc

and a SC02COMLPL************.zip, extract the zip and

hopefully you should now have the relevant file: SC02COMLPL_SC02CDCMLPL_SC02COMLPL_HOME.tar.md5.

Now you need to put your phone into download mode. To do this power-off, and now simultaneously press

volume-down, homebutton and power button till it goes into 'download-mode'. Do volume up (continue) and once

in the "Downloading..." screen connect USB to computer.

Now fire up odin make sure you have a yellow square there that says something like "0:[COM10],

make sure the only boxes ticked are "auto reboot" and "f.reset time", now select pda and point to

SC02COMLPL_SC02CDCMLPL_SC02COMLPL_HOME.tar.md5. When you're

ready press start, and wait till it says finish, your phone will restart and you can now d/c usb and close Odin.

When you turn on your phone again, it'll take a while, but you should able to confirm (by going into settings>about>) that you now have

sc02compl, the latest sc02c firmware.

2. ROOTING:

Download:

https://dl.dropbox.com/u/20242742/phones/sg2/Siyah-v3.5.2-CWM.zip

Factory Reset (settings>backup and reset>factory data reset)

Odin PDA v3.5.2 Siyah kernal

Turn off the phone

3. UNLOCKING:

Download the following:

https://dl.dropbox.com/u/20242742/phones/sg2/Galaxy_S Unlock.apk

Connect to Wifi internet connection!!!!

Copy the above .apk to your phone through usb/wifi.

run "my files" the samsung file manager and install galaxy s unlock.

** in case the sc-02c doensn't have a file manager run CWM (clockwordmod manager) and install the galaxy s unlock.

***Now just to repeat these 3 conditions should be met before running Galaxy S unlock - live internet, busybox and root.

run galaxy s unlock

do Unlock>1. save actual efs folder>2. sim unlock.

wait forever while it goes black and appear to do nothing then power off

when it says to reset.

put a sim card in, power on and hopefully all is well and your phone is unlocked.

Let me know how it goes.

CM9 - Siyah kernel Docomo Samsung Galaxy S II Installation

I knew I would have difficulty.

I keep getting a Status 7 error when trying to install CM9.

But I just kept (thinking of brickbug) deleting/factory reset until it worked. I also installed the CM9 build prop thing. I think the first time I did that it did not take so I did it each time before trying and finally.

So this is what I did...

Backup first using CWM

Download all the files and have them waiting in the root directory of your external card - CM9 ROM, Siyah kernel (version doesn't matter but 3.5.2 has been good to me), Gapps.zip (google it), ntt specific zips/tweaks etc.

Remove the Docomo FOMA SIM card not your SD card (hint: it's the white one)

Go into CWM recovery and then factory reset (make sure you are not on stock kernel - Siyah was on here first)

While still in CWM recovery, install the CM9 rom

wipe dalvik

wipe cache

install gapps.zip

install Siyah kernel again (i did for good measure and I don't think that you have to but...)

you can reboot here or

install tweaks and then reboot.

after you boot up login to a wifi connection and let things get setup - your gmail etc.

then turn off the phone and reinstall your FOMA SIM card

reboot

after it turns on go into settings > more... > Mobile Networks > Access point names > click your menu key and then New APN

add whatever name (not sure if it matters)

under APN type 'spmode.ne.jp'

hit menu again and save

connect to that APN and give the phone a few minutes to connect and then disconnect your wifi and try to get online

I will clean this up and add more as I think of things

I am testing it all out now and will let all know if my ranting (mainly to myself while you all listened ;-P ) worked.

battery issues etc....

off to install some apps and play around....
[Galaxy S II General] SimmoF:
Oh, I know your preoblem. CM9 won't install cos you have an sc-02c rom not a gti-9100 rom.

downlaod cm9, extract this file "META-INF\com\google\android\updater-script"

Remove the

assert(getprop("ro.product.device") == "galaxys2" || getprop("ro.build.product") == "galaxys2" ||
getprop("ro.product.device") == "i9100" || getprop("ro.build.product") == "i9100" ||
getprop("ro.product.device") == "GT-I9100" || getprop("ro.build.product") == "GT-I9100" ||
getprop("ro.product.device") == "GT-I9100M" || getprop("ro.build.product") == "GT-I9100M" ||
getprop("ro.product.device") == "GT-I9100P" || getprop("ro.build.product") == "GT-I9100P" ||
getprop("ro.product.device") == "GT-I9100T" || getprop("ro.build.product") == "GT-I9100T");

Save and put back in the zip and overwrite the old file. Now flash this new file.

From what Ive heard, the brick bug only affects stock roms.

Also if you are paying the Docomo insurance it doesn't matter if you fcuk it. They give you a new phone.

Worked for me, I had a flash counter of like 80 and the usb port was broken and I had a custom rom :D
[Galaxy S II General] DenisGuy:
First I would like to say: thank you very much for taking the time to help me.

That being said, I already know / have done what you are telling me to do here.

The only question I have is: since I'm already rooted, I have a custom rom, Siyah's latest kernel, and Busybox, what would be the reason why the changes in the EFS folder wouldn't stick? It works fine until I reboot! I am suspecting myself that the Kernel is not allowing me to keep the changes I do to my root folders. However I have no idea why. Is there a way for you to explain to me the reason why? Or am I just better off doing everything from scratch?
[Galaxy S II General] rushter:
I found that online and was getting ready to do that when I found what I think is the file to fix that. It's the page on zaphod777's signature.

Besides I started to do that but could not save the file back as a Unix executable. So I tried that other thing. I think that's what fixed it.

But thanks.

On a side note, I had severe battery problems when I first got this phone and they replaced the phone once and I still had the problem. It turned out to be the FOMA card.

This time though I think the cheap extra capacity battery j got online may be to blame. After CM9 install earlier today there was a point where it was at 58% and five minutes later it dropped to 17%. That made me remember the other day messing around with CWM it did the same thing.

Time will tell but I really like CM9 so far.
[Galaxy S II General] zaphod777:
Good job :) sorry I didn't have time to respond to your PM. Today was a crazy day.
[Galaxy S II General] rushter:
No problem. Any way to delete all of those extra APN's that are in the APN list?

Here's a weird one. After I finished all of this stuff that I did to my phone I saw that everyone was saying to go ahead and install the modem and ril file or whatever so I downloaded that and went to put it on my sdcard. The sdcard was an empty directory. Where the hell did all of my files go? My backup etc?

Update: in recovery mode all the files were there. Odd.
[Galaxy S II General] dhaub:
I encountered the same problem once; try from scratch, it worked for me.
[Galaxy S II General] rushter:
Ok, CM9 is great so far. I am using the smaller battery (stock) and have lost about 25% in two hours. But I have been installing a bunch of apps etc. Tomorrow will be real test. Thanks xda and everyone.

Again, cm9 rocks.
[Galaxy S II General] SimmoF:
When you install a new ROM the battery gauge is bad. You need to drain it once and charge it fully for the ROM to detect the correct values. The rom checks the mV output and converts it to a %. Based on what it knows the battery can output.

The battery does not put out a % value. On a new ROM, on a new ROM it does not know what mV is full and what MV is empty. You need to train it. It will take 2 days about for a reliable reading.
[Galaxy S II General] rushter:
Ok I'll say it again. CM 9 rocks. If you are using a Samsung Galaxy S2 on docomo, you need to root and get this setup.
[Galaxy S II General] DenisGuy:
#1- Your guide is missing a very large amount of steps. But it's ok, I'm no idiot.

#2- Still no sim unlock. Again, it unlocks it but locks back in when I reboot.

I'm unhappy, but hey. Things happen.

Thanks anyway.

---------- Post added at 04:00 PM ---------- Previous post was at 03:15 PM ----------

You'll love CM10. The only "known issue" is that you need to reboot it once in a while because the RAM fills up and doesn't wanna empty itself. Other than that, it's awesome.
[Galaxy S II General] SimmoF:
Today I'm testing the sc02c ICS+jb kernel from ma34s because the battery life of Siyah 4 is unsatisfactory.

He/she has taken over SakuraMilk's kernel.

So far it seems quite smooth, I'll report later today or tomorrow on the battery life.
[Galaxy S II General] wjchen0:
Most battery drain problems caused by background running apps.

You can use betterbaterystats to see what happened.

Usr autostarts to disable some app's unwanted autostarts.
[Galaxy S II General] SimmoF:
Its a kernel drain, as different kernels drain at different rates. Even if BBS shows nothing out of the ordinary.

Siyah 4 is known to lose power faster than other kernels. There are many threads about it.

It's a shame, I like Siyah.

The best kernel I have is wjchens Siyah 3.5.2 NTT build.

Can't stay on that forever.
[Galaxy S II General] DenisGuy:
wjchen0 and SimmoF ... I have 2 questions for you you might be able to answer:

1. How come the modifications I make using Helroz's Galaxy_S Unlocker won't stick? The unlock works but I have to re-unlock every time I reboot.

2. I know there is a way of adding a startup script that would force the unlock app to be re-run at every startup, which would be a workaround for me*. Could you please point me to a solution?

I'm on CM10 and Siyah's 3.5.2.

Thanks in advance.
[Galaxy S II General] wjchen0:
Not sure about the Galaxy_S Unlocker app.

Someone says unlock success.

You and one of my friends get temporarily unlock(disappear every reboot).

You can go to docomo shop to get an official unlock,or buy a remote unlock online.
[Galaxy S II General] yusuf7x:
@DenisGuy

I have same problem with you, my phone locked every reboot.. that thing happen after I instal paranoidandroid 2.10 with siyah 4.1.3

What i'm do is

1. back to gingerbread stockrom (OMKL4),

2. instal siyah 2.6.1.4,

3. instal titanium backup (i got busybox from titanium backup app),

4. if u have folder galaxy s_unlock on your sdcard, deleted that folder,

5. instal helroz unlocker, and then unlock your phone

6. Instal custom rom (in my case i instal paranoidandroi 2.10)

7. Stay with default cm10 kernel for few days, because i think siyah 4.1.3 will locked my phone again

8. And then instal siyah 4.1.4

Until i wrote this post, my phone still unlocked

Sorry for my very bad english, i hope you understand :)
[Galaxy S II General] DenisGuy:
I do understand. Thanks.

The problem I have is when I go back to stock and install siyah 2.6.1.4, the phone wont boot anymore. Then if I install the cm9 build prop and a custom ROM, I have no issues booting.

Let me be more clear:

When I go back to stock, the phone stays stuck at the Samsung logo.

Then if I go to recovery and wipe everything, the phone boots stock.

But whatever I do after installing siyah 2.6.1.4, I can't get it to boot. I need to install a custom rom on top of it.

????
[Galaxy S II General] wjchen0:
You may not understand this "1. back to gingerbread stock rom (OMKL4),

".

Siyah 2.6 is for 2.3 rom。

Siyah 3.x and 4.x is for 4.x rom.

Install OMKL4(stock 2.3.6 rom) first.
[Galaxy S II General] SimmoF:
Anyone else getting a sleep of death with CM10?

It usually happens when my phone hits 100% charge and it switches to usb power mode (charging stopped).

I get the issue with Siyah 3/4/Siyah based kernels and the kernel I was referrign to earlier today.

Anyone got a fix or an idea? It happens regularly for me. Daily.
[Galaxy S II General] DenisGuy:
AH! That might help.

But I don't wanna go back to stock now. I might start sobbing uncontrollably if I have to wipe everything one more time.

AAAANYWAY I can't find the 2.3.6 stock kernel. All the links I found are dead. And Fus Downloader doesn't let me download the old one. Can anyone point me to one?

Thank you very much for your help.
