CM9 sc-02c help

Hi was wondering if someone could please help. I have installed the latest CM9 nightly build on my sc-02c together with sakuramilks latest kernel and modem. The phone boot fine and works for calls however no matter what I do, I cannot get data to work (wifi works fine). In about section it says mobile network state disconnected if this makes any difference? Does anyone have any idea how to get data working (3G or H+). I have tried other kernels (siyah), but cannot get data working. Please help, I am sick of flashing endlessly only for it not to work.

Thanks

Apn problem.

It's not kernel problem,just because APN settings is not right,it depends on your mobile network service.

Installed CM9 on my SC02C (CM9 nightly 20120404, OMKL4, Syiah 3.0.1-ntt).

I frequently have crashes (couple of times a week), but that I can live with.

My biggest problem is that sometimes I suddenly lose all connectivity. Connectivity bars at the top-right are grey even tho I am 100% sure to be in coverage area (not sure but I think there was a 3G symbol and I could see some grey separate bars moving so there was still something going on but still it wouldn't turn blue -- will make sure of that again next time).
Sometimes I don't even notice it and go for hours without any signal until I try to browse/call.
A reboot fixes it.

Any body experienced the same symptoms? Not sure if it's CM9 related and/or SC02C-specific.

Next time it happens I will try to dump logs and check phone status (usually happens to me when I'm on the go so can't really check it well).
You're problem is that the kernel you flashed is not for ics. Its for gingerbread. Fillow @sakuramilk on twitter and download his kernel. Im running cm9 0414 nightly with his latest kernel which he posted a link to on twitter. It has working gps and good battery life.

If you're on docomo and paying for spmode data pakehoudai then make a new apn with the address as spmode. Ne. Jp then save and select it. Your data should work immediately after

SC-02C : CM9 nightly 0414 : Sakuramilk Kernel

mr_villagomezis right but he has a typo, probably cos he replied from his phone.

Anyhow goto settings->mobile networks->access point names
Menu->New APN
Name: spmode
APM: spmode.ne.jp
MCC: 440
MNC: 10
APN Type: default,supl
APN Protocol: IPv4

The rest are not set/unspecified.

FYI guys do not flash any Siyah 3.1RC6 from yesterday. If you wipe your phone it will brick your phone. It may be only a soft brick but so far no one has been able to recover.

It is safest to only use 3.1RC6 dated today or later. Personally I am still using 3.0.1 stable to be safe.

Hi, I'm having an issue with the clock app. It's happened on all ICS versions I have tried. When you press Create Alarm it freezes the app. I am using SakuraMilk's kernel now but it happens on Siyah too.

Anyone else having this issue or fixed it?

It works fine for me with CM9 and Siyah 3.0.1

It's not a kernel issue.As far as I know,in some old version official rom the clock works bad,you can try third party clock app.

i am now using simmon mod of sakuramilk kernel but sometimes the wifi cannot work after you turn it off. It shows turning on for a long time. Any solution for this?

Also any suggestion for the cpu setting? Max min cpu frq and governor I/O scheduler. I want a compromise between smoothness and battery

This is a known issue with CM9 I think the Siyah Kernel dev said CyanogenMOD mad some changes that caused this. He has fixed it in his kernel and just released 3.1 but I am waiting until the dust settles since yesterday he had a release that bricked some devices under certain conditions.

I have my CPU set to a min of 200Mhz and a max of 1000Mhz. I am also using the Conservative governor. Battery life is OK, not as good as it was with GB but as more CM9 dailys come out and the kernel dev's work harder battery life improves.

Just updated my mod packs for ease of installation.

I have made another for wjchen's speedmod-mod.

The new versions, install Apex Launcher and BetterBatteryStats to the /data partion now instead of /system
Apex now supports the Superuser app, so it doesn't need to be in /system anymore.
I also changed it from installing a premade gps.conf and now it simply patches the one already on your system.
I removed the GPS static navigation patch, if you want it you can use the app to install if you want it.

Simmo's mod with SakuraMilk's nightly 20120422 kernel.
Simmo's mod with wjchen's Siyah 3.1rc6 kernel.
Simmo's mod with wjchen's SpeedMod k3-11 kernel.

XWLP8 works a dream for me with this patch works a dream for me.

I am using a 1% BatteryMod on mine too, if anyone wants I'll post a link to it.
Dear Simmon can you upload the kernels again? the link expires

Gokhan upload many versions of siyah3.1rc6,the version compiled by me is the oldest one,based on international ics source,won't brick your device,only a version of siyah3.1rc6 based on korean ics source might brick device.And the latest siyah3.1 is also based on international ics source.
Wifi toggle issue is a bug of samsung kernel source,I'm testing some solutions,not sure it work or not.

Awesome, I just wanted to check and make sure. I see you are on top of it. I am still sticking with 3.0.1 since I don't care about dual booting and want to wait until there is a good stable one to flash.

I read that some people were having issues with the new mount points. Will it work OK with cm9? I haven't updated to the latest cm9 yet.

I'm using official rom,not very sure,you can have a try.
If you want to use old kernel,add a script in /system/etc/init.d/,this may fix wifi issue.

Update:
The min_free_kbytes default value is 3606,increase it may fix wifi toggle issue.
I set it to 16384 and works fine for two days.
Other value such as 8192 may work,but need more tests.

Code:
#!/system/bin/sh
echo 16384 > /proc/sys/vm/min_free_kbytes
