[Q] No Data Connection ICS - Galaxy S II Q&A, Help & Troubleshooting

Hello I have a question about ICS. I upgraded my Galaxy S2 from 2.3.6 tot 4.0.3 with the LUX ROM. I did wipe data and cache before I flashed the ROM. So everything went well, but there was no 3G connection. There is a little triangle at the top with: ! in it. It says Data connection lost because outside of home network. So, I tried the baseband that was working with 2.3.6. That was KI4 but still no luck. Tried other basebands with no luck. I can call and sms but there is no data connection. I also tried another ICS ROM (poland). Didnt seam to help either. So I flashed 2.3.6 back and everything is back to normal. 3G connection working.
So, why doesn't my data connection work on ICS roms? I also put the right APN settings btw. That cant be the issue since I also have to put those settings in GB. Same settings, but ICS still no data connection.

where you from mate? i had that problem before, i solved it through looking at the APN. check it first if you have tick it or not, if so check your proxy delete the proxy number.

Im from the Netherlands. The APN settings are the same as the settings I use with GB. And I have a data connection with GB. There are no special APN settings for ICS, right? And I dont have a proxy and I have ticked it ofcourse

Smells like wrong CSC for your location or baseband not working flash another modem .
But as you have tried it could also be a faulty flash flash again .

[Q] no data connection after flashing a custom ROM

Hey guys, i have searched plenty of threads with no fix in sight. I was running stock J12 and flashed Frankin-Twiz Final. Flash went fine, but i have no data connection through Tmobile (3g or Edge). My apn is epc.tmobile.com and it is selected. Everything looks fine. I odin'd back to stock, flashed Bionix's newest and the same thing.
The thing that is weird is that flashing back to stock fixes the data connection, 3g and EDGE show up like they should. Any help would be much appreciated. Thanks in advance.

Internet not working, even on data package?

Fixed!!!!!
Thank you! :d
Try - Settings>Wireless and Network>Mobile Network>Access Point Names>*menu button* Reset to default
I forgot to say it's unlocked! That didnt work.

I made another post yesterday about my girlfriend's phone being messed up because it was on i9100. The buttons didnt work and she couldnt hear calls and such.
We reflashed and now its back on i777 and she can hear her calls, and buttons work! It's still rooted.
However, we cant get her internet to work with her data! Wifi works perfectly but the data does not!
Is this a phone problem or a provider problem? Any suggestions?
ADD: I forgot to say it's unlocked.

Did you reflash the modem? It's a separate package in my thread.
Settings->About Phone should report a UCKH7 baseband. If it's something else, you need to flash the modem. Also may need to wipe data/factory reset in recovery.
I did reflash the modem thingy, I figured that would fix the calling (which it did).
Settings < About Phone reports a I777UCKH7 baseband for her, yes.
I'm puzzled as to why it would work with Wifi but not her data. Im not sure if it was set up incorrectly by her provider (she had data previously on her HTC desire) Or if it's something going on with the phone that we need to fix.
Make sure 'Use packet data' is checked under Settings>Wireless and Network>Mobile Networks.
Yep, that is currently checked as well.

[Q] Data connection not working after flashing custom rom :'(

I'm having a problem since I flashed the sensation rom (by crysis21) on my SGS2 yesterday.
My internet connection (mobile network) doesn't work anymore
I checked the APN settings and already resetted them and enterd my APN settings again. But it still doesn't work. I also restarted the phone multiple times.
Does anybody know where the problem is?
Installation steps were:
*copying the rom to sd
*CF-rooting the kernel via Odin
*booted up in CWM recovery and chose "install from zip file" and installed the rom (without any wipes)
Before I had the default samsung factory rom on it.
Have I made a mistake?

Have you checked the APN settings are the good ones? One thing is to have ones enabled and other totally different is to have ones that actually work.
Also when you go from Stock to Custom ROM you should do a full wipe!
Go to CWM and format /system, /data, /cache and reinstall the ROM.

thanks, I'll check this out as soon as I get home.
I refrain a little from doing a full wipe because I don't want to get all my apps deleted (and I'm a little too lazy to perform a backup). Would mybe a new modem solve this problem?
And of course I checked the APN settings. I deleted the existant APN setting and added a new one so the settings can't be the problem.
I also checked some entries in Settings/Phone Info/Status.
It says here (translated from german):
Mobile Network Type: HSDPA
Service State: Function (or working rather)
Mobile Network Status: Disconnected (but sometimes it says also connecting here, though it never really gets conencted)

lunatikk
Even though I wiped everything, the data connection still doesn't work.
I did
"Wipe data/factory reset"
"Wipe cache partition"
"Wipe Dalvik cache"
and after that I installed the Sensation rom zip file again.
The data connection still doesn't work :'( (I added the APN after install, of course - the settings are 100% correct).
I also installed another rom (infected rom) but there's still no data connection.
Am I missing something? I'm getting really desperate over here.

You could try flashing another Stock ROM via Odin and see if in stock works or not, then try a Custom ROM.
Sometimes the phone takes a while once you flash a new ROM till it establishes a decent 3G connection. Having "Data enabled", how much did you wait for the phone to establish a connection?

I thought so too... Well, at work I waited some hours for the data connection being established but nothing happened.
This is crazy. I even restored my system with CWM and it still ain't working.
As soon as my GF comes home I'll replace the sim cards. Maybe the problems at the providers side...
after that, I'll try a stock rom (via odin).
thanks for your tip

I have the same problem and I'm on check rom.
i'm having the exact same problem, but with multiple roms and not just one. i tried omega and delv. both of these are giving me no data connection (only at the beginning) but once i restart there's no data connection.
did you manage to figure out what went wrong? I've resulted in my original rom that i had by restoring it using cwm.
dear sir,
my device is micromax canvas a1 aq4501. when I recovering a custom rom like cm13 my device Internet data not connected. I fully checked setting like mobile data, apn, but it still not working.
now I want my device situable custom rom. please give me the right information.

No 3G + heating up problem after XXLPB

Hi guays,
this is my first post I didn't find any post very similar to what I'm suffering.
I flashed my galaxy s2 with the brand new I9100XXLPB and half of battery charge.
Once flashing process was complete, phone power on correctly I set correctly my provider's APN configuration but I only got G not 3G in automatic mode. If I switched to WCDMA only, I got H+ but if I switched again to automatic mode it gets back to G. Then phone starts to heat up and drain battery so fast until it poweroff.
After cool down I charge it and try to connect to 3G but had the same results. So after check the configuration with autoconfiguration message send by the provider I decide to get back to 2.3.6 in which 3G worked perfectly and now I can't connect 3G anymore but I can connect to G. Configuration parameters of APN are correct I wipe data and cache before and after the update and there is no way to make it work again.
Any idea? I don't know if the heating problem has the fault of this behaviour because it is the only rare thing it happened.
Beta buggy test rom then excpect problems until ICS released by Samsung .

I know it's a beta and bugs are usual, what I don't understand is why 3G doesn't work if I go back to a 2.3.6 firmware (xxkk5) when before the update to ICS it worked perfectly with the same firmware. Any suggestion of what should I do in order to make 3G starts working again?
Thanks
Do a full wipe and reinstall, or go back to GB.

Hi, you could try flashing a different modem from an older s2 ICS leak from the cm9 development thread, which may help with your 3g problems, I hear that has worked for some people: http://forum.xda-developers.com/showthread.php?p=20671183
But if I was you, I'd re-flash the ICS rom (after a full wipe data, cache & dalvik cache), if the problem persists, then try a different modem with the rom. Then, if you still have the problem I would flash back to GB, and I would wait for a newer release. I hope this helps
try to flash another ics rom. I had a same isses like u.
Thanks guys for your help and advices. Finally I managed to get 3G work again. I flashed again to GB after user data and cache wipe and getting the configuration data sent by my provider. It's weird because I have already done this 3 or 4 times before but now it is working.
Again thanks all of you for your help
Am also having the same over heat and battery problems with ICS from XXLP2 to XXLPB
hope that Samsung figure out a solution

[Q] ParanoidAndroid (and other) JB ROMs - Can't get mobile network to work

I can't post to the dev forum, so maybe someone over here can help:
I tried the PA ROM, because I really love the hybrid mode. The ROM has worked fine and looks great, but whatever version I flash, the mobile network, both data and phone, simply doesn't work.
It briefly connects to my provider (drei.at) and immediately disconnects, no matter whether I have data connection enabled or not.
Have tried this with all available versions of PA and did the usual routine: wipe, format system, wipe data. I even went totally back to a stock ROM, tried various modems, the current one being XXDLH9, which works just fine on [email protected] 0.6 ROM.
Had the same problem with Omega, FoxHound, and god knows what other ROMs I tried. No matter what, the only JB ROM actually working is [email protected] 0.6, that's it.
Is this a known phenomenon or have I overlooked something obvious?
The phone used to be a branded and simlocked Austrian T-Mobile, but ever since it has been debranded and SIM unlocked.
Any ideas?
All i can suggest is your apn settings?
Can try Offline SIM APN Database (get on Google Play) to insert the correct apn settings.

Thank you for the suggestion. The APN settings on a fresh install, all wiped, are correct and the same as in a working setup.
Any other ideas? Am I really the only one with that problem?
Modem tried APN correct .
Suggest next step is factory reset ..
Step after that is to install an official stock rom .
Others who may have a problem post in the roms thread .

Did a factory reset, totally clean install with everything wiped.
Also, did a clean wipe and installed official stock ROM. Lost root, started from scratch and still didn't work.
I'd love to post in the ROM forums, but haven't yet posted my mandatory 10 postings.. Maybe this thread helps me to reach that limit

No, that's not what I said. Stock ROMs work just fine; I actually just flashed the latest leak (DLI5) and had no problems with the network. The problem hasn't changed, so it's what I wrote in the OP: Only JB to work ist latest leak and [email protected] 0.6. All others can be installed but have not network connection other than WiFi.

Have you tried flashing a new baseband? i had the same problem, when flashing the franco. Kernel..
or, go back stock, then reflash the desired ROM
EDIT: If it helps, I speak/write fluent german ('Cause I live in germany ^^)

Thanks for trying to help.
Yes, I have been playing around with all kinds of basebands, trying to flash modems etc. but that does not seem to be the reason for it. I have had different modems working and the very same modems simply did not work with PA at all. Best example ist yesterday's leak DLI5 which I flashed and had a virgin like system working just fine with my network. I then flashed the PA ROM, which then had the same baseband as the latest stock ROM, but, alas, same story: No network.
The weird thing is the brief connect it always shows in the status bar. It lasts roughly 4-5 seconds and then disconnects again, only showing the empty network status display.
It really sucks, because I find the idea of hybrid ROMs really appealing, in fact, this seems to me as a truly superior way of making use of the 720p display.
Need to try logcat next to see whether the connect/disconnect somehow can be monitored from there. Will report on that.

I just installed ParanoidAndroid. I'm kind of a noob to all of this.
I understand some, but not all.
My mobile networks are not working.
I don't get any notification at the top of the screen either saying I'm on a mobile network.
I've messed around with the APN settings. It seems that every now and then it'll connect for a brief moment, but I can't really do anything unless I'm connected to WiFi.
Any help would be appreciated.
I came from a stock phone rooted.
Installed this and now I'm here.
Please HELP!!

Turns out I just had crappy reception at home.
I wanted to get 3+ but something got in the way and had to go with the 2.+
Sorry for not understanding, but what is AOSP? I see that, but I don't get what is what.
ASOP = Android Open Source Project.. They are best but not that much good at battery
Spend some time on xda and Google your doubts.. You'll surely understand everything from android
