[Q] Toubleshoot 3g on SGS2 after rooting - Android Q&A, Help & Troubleshooting

Hi all,
I have an issue on my SGS2 when I flash some custom rom. I'm a big fan of Darkyrom and I only flash their stuff though
Since the first flash on my device my 3g doesn't get back online directly.. Nothing I do in the APN settings or on/off mobile data affect this issue. The only way I found to get the 3g back again is using the app APN Manager and.. the option turning off the APN makes my 3g working again. weird but hooray on gingerbread.
But on the new ICS roms, APN tools don't have access anymore to these settings. I tried backing up the apn-conf and copy paste from a root file manager without luck. But I don't have any idea what this "Turning off APN" from APN manager trigger to make my 3g working again.
Any help would be much appreciated
Thanks
Edit :

Model : GT_I9100
Android version : 4.0.3

Anyone?
The mobile network state is : Disconnected and sometime changes to connecting, but never connected.
Thanks

[Q] 3G,EDGE,GPRS dont work on i5500 after flash

I briked my phone recently" after instaling chainfire 3D",i dont know what ROM version i had before that but i used ODIN to recover my phone ussing another version of ROM.I managed to find FROYO 2.2 available(support) for my country( Romania),but i noticed that mobile network is not working anymore(except Wi Fi),
before this mess the 3G ,GPRS or EDGE signal was present and i have the option to turn on or off the mobile connection,but now i cant do that anymore and i dont have 3G signal anymore,and I dont know why because i have the correct settings in APN. In "About phone" / "status" i have the following values:Mobile network type: UMTS or GPRS from time to time, and for Mobile network state is DISSCONECTED or Connecting from time to time.When i long press the end call button the Phone option appears and when i chose Mobile Network option (Connect to internet is OFF) it does nothing....Can anyone help me in this problem ?,some say that there is a secret code for service that test the 3G conecction but i dont belive that......?..For this reason(problem) i installed four different versions of ROM,and my best option is to manage to find a solution for the current ROM that i have)Sorry for my english or for my posible double post...
I found the official stock ROM i had before and fixed the problem with 3G signal,Is very important to use the correct ops file,i used EUROPA_I5508_v1.0.ops(because i'm an idiot) and the one i needed was EUROPA_I5500_v1.0.ops and i think that is one of the reason for the lost of 3G signal.

Galaxy Tab 7" (SHW - M180S) problem

I purchased Galaxy Tab 7" Any call from Korea last week and got it with me to Egypt, with the following specs:
Model number: SHW - M180S (SEC-SHWM180S(B))
Firmware Version: 2.3.6
Baseband version: M180s.EH12.1526.ST
Kernel version: 2.6.35.7 ([email protected] #2)
Build number: GINGERBREAD.Tj24
S/N: R14B199307
The tab is working very good but one option which is it can not connect 3G for data browsing (Can not surf the net), after entering the settings--->Wireless and network, i found an option 3G data call settings dimmed so I cannot change the settings. I tried the Sim on my HTC it worked with no problems.
Please advise how I can use the 3G on the Galaxy Tab, I worked on the 3G at Korea and there was no problems !!
Thank you very much
hrmy
We have the same problem and unit came from korea.
Set your apn settings if correct.
Download to the market 3g Auto connection it free. After you download. Change the connection mode to use direct mode. Check the advance setting to have wigget in home screen. And back to home. If you want on the 3g. Just on the 3g and they scan. Then back to home. On the wifi even there no wifi signal after 2 to 3 sec turn off wifi after that the 3g icon appears. That it. Now you can use your 3g. I hope that i help you. You can browes your net to your dolphin hd and other. Not on our original browser. Becouse our 3g call setting was disable and dimme.
Thank you very much.

[Q] Where can I find CSC for my SG2

I would like to know what is the difference between Phone and CSC on Odin 1.85
and also would like to find out whats the right phone and csc for my phone, after I rooted I lost complete mobile network reception inside my home.
I'm on giffgaff, which runs on O2 network,
before I rooted my kernel was xwkj3, and I had xwkj1 I think for my modem, but I don't remember
I have rooted using this CF-Root-SGS2_XW_XEN_KJ3-v5.0-CWM5.tar
after I had a read around this was the right modified kernel, but since then I can't make calls or receive calls inside my house, only when I'm outside, and what strange my gf has an htc hero, with giffgaff simcard, and her phone always have reception inside the house, like my use to, I know is not the sim card, as I have tested on her phone and works like hers 3 bars, and I have all the mmsc and apn all setup accordingly to giffgaff, so I know is not that.
narrows down to the wrong CSC or Modem, other than that I can't figure this one out, and I have flashed and reflashed with odin several times, I don't even bother updating my software and apps, cause I know it will all be gone from my internal mem card,
ABOUT PHONE
ANDROID VERSION : 2.3.5
BASEBAND VERSION: I9100XXKI3

BUILD NUMBER: GINGERBREAD.XWKJ3
MODEL NUMBER : GT-I9100
PDA:I9100XWKJ3
PHONE: I9100XXKI3

Please help me sort this out, I have not been able to receive calls or call, and I run a business, and if people can't reach me at home, I'm out of work.
Please Help, thanks
in the most sammy roms , CSC is included in PDA zip or .tar , try CheckFusDownloader_v2.1.exe , and search for original ROM for u'r network , download it and flash it with ODIN 1.8

Root has nothing to do with network .

Any modem will work on the Giffgaff network .
after I had a read around this was the right modified kernel, but since then I can't make calls or receive calls inside my house, o
Thats a fact of your network or possibly modem .
narrows down to the wrong CSC
CSC nothing to do with it especially if you have set network manually or via the Giffgaff apn settings tool .
Suggestion would be to flash the KL1 modem .

Thank you for your answer. I have already tried this and I've also reverted to Omega v13 ( Ics based) wich have a different modem.
Hi cp108,
I had the same problem when I install the Omega ROM v27.1(Modem XXDLIB : same modem that your device has) on my Samsung Galaxy S3 i9300. Then I changed the access point name settings and data connection turned on. Have you changed following attributes?
1. Name
2. APN
3. Proxy
4. Port
5. MCC
6. MNC
7. Authentication type
8. APN type
In my case, after I changing above the problem solved.
