I lost countless hours looking for an answer and still looking how to fix it.
after I rooted my SG2, the mobile wireless has no bars, checked to see if was the sim card, and is not as I have tested on my gf htc hero, and works fine.
I have then unrooted to see if the problem would go away
and is still with no signal when I try to call someone says
mobile network not available

Flashing a kernel shouldn't have done this. Sounds like you either flashed a firmware package that included modem files for a different carrier, or accidentally flashed a different modem, which isn't for your carrier.
Do you know what other carriers are compatible with giffgaff?
Is your firmware carrier branded? I would just flash the latest available firmware for your carrier if it is branded, or if not branded, KI3 or newer from the unbranded thread.
Carrier branded firmware thread is here.
Unbranded firmware thread is here.

It's a little late for that. His problem now is not getting root, but getting his phone working again. I suspect he'll have no choice but to flash SOMETHING to get it functioning again.
I have used odin 1.85
then I rooted with this
CF-Root-SGS2_XW_XEN_KJ3-v5.0-CWM5
I have not done anything else
and I have no signal inside my house
when I go outside I have signal, but is not the sim card, and was working before
this is doing my head in
my carrier is giffgaff
the phone is unlocked and giffgaff runs on O2
You want to set up network .
Use the GiffGaff Tools/Apn app from the market or Giffgaff forum.
Giffgaff will work as O2 PAYG if not set .
You say Mobile wireless do you mean WiFi if so nothing to do with GiffGaff try flash a different modem .
Root should not have caused a problem .
Are you sure you have a i9100 .
and I have no signal inside my house
when I go outside I have signal,
That is simply the network your house is blocking the O2 signal .
you can check your nearest O2 base station

You have a choice
One flash a modem from the modem thread .
Two flash full original stock rom from stock rom thread that will remove root .
Three ask the network is their work on the local transmitter .
Four ask the network to move the transmitter to your kitchen .
Why did you root ???
What is your current modem ??

Type *#1234# into the phone pad and what is shown against PHONE is your modem number.
As the previous poster suggested I suspect that you have inadvertently changed your modem. I am on Giffgaff with the original O2 firmware on the phone. The modem for this is XXKI4. I understand that the previous modem was XXKI3.
You can download one or both of these modems from
http://forum.xda-developers.com/showpost.php?p=17967764&postcount=5
Please read carefully what it says. i.e. The zip files are intended to be flashed from your internal or external sd card using clockworkmod (CWM) recovery (you have this as you rooted a CWM kernel) and should NOT be flashed using ODIN. If you want to use ODIN then you can extract the modem.bin file from the zip and flash that from the PHONE section of ODIN.
Hope this is of some help.

When I search networks I do get O2 in the list. You wont get Giffgaff as it's not a network but uses O2's.
It may be that for some reason O2 are putting out a weak signal in your area. If your phone is unlocked have you tried sims from other networks to see if you get the same drop off between inside & outside the house. If you do then it would suggest it's the phone (hardware or firmware) but if you don't or the drop off is much smaller then it might just be an O2 signal problem. If you know someone who has an actual 02 sim then perhaps you could try that as well.
I know is not the Sim card, as my gf uses giffgaff as well and I tried on her HTC hero, and has 3 bars, works fine.
I just don't understand why when I rooted the phone the phone network coverage inside my house went to nil, and when I get outside my house and around town I have full bars and 3G is working, I only able to use my WIFI inside my house and Bluetooth.
which is a Pain in where the sun don't shine, because how am I spose to receive calls or call anyone in the comfort of my Home, impossible so people will be thinking that I'm ignoring them, or think I'm rude.
I will try other sim cards and see if that will be the problem.
thank you
you been very helpfull, will report back later
I sometime have this problem all i do is restore efs back using ktool. If you made efs backup using hc-ktool try restoring that and reboot. Your mobile signal will start working again.

I've just noticed that you've put down your CSC as I9100oxaki3. Is this correct? Because I think OXA is a country code for Poland. If it is then perhaps you flashed a firmware intended for Poland. I don't known whether this difference in CSC setting would affect your signal. I'd always thought that the call side of things was handled by the modem and the XXKI4 modem is definitely UK compatible. I may be wrong though.
If nothing else is working then perhaps you could try flashing a firmware with a CSC that is UK specific, includes the UK or is generic European. Post #2 has a link to available firmwares.
I am not sure what suggest then. When i rooted my phone first thing i read was to backup efs using ktool which can be downloaded from market. Then i used cwm manager to backup stock rom. Check in your sd card if have efs folder if yes download ktool and use an option to backup efs and restore using the tool it will ask you if you want to restore by .tar method choose that. It all depends if your phone has efs folder and files init.

As a relatively small network GiffGaff may not be in older or even newer CSC network lists /
Use GiffGaff APN tool .
OXA is Poland
You do not need a CSC to use the phone GiffGaff settings either manually or via the GiffGaff tool

I fixed the Phone, finally,
it has 3 bars now and its the way it was, but I lost all my settings, easy to fix though.
heres my new info

I'm not sure if its rooted or is flashed back to stock what I did was
use odin 1.85

and clicked Start
and after that, was set to factory reset as it came out of the Box
It did not delete my software that I had on my internal 16Gb, but is not active
so I have to re-install the apk again, and add contacts from my facebook and google account.
O2 network appeared I registered on that and I set my apn for giffgaff and is all up and running, thank you so much for all your help, anyone around newport area, I'll buy a Beer

Hey,
My Samsung galaxy s2 will not receive or send any calls or texts whilst i have my contract virgin mobile UK sim in, the mobile internet still works fine though. I can use the phone with a 3 sim in even though it was locked to Vodafone when i got it, It's not a problem with the sim either, i can put in in other phones and it will work just fine.
I've tried flashing many different kernals and firmware in the hope to fix this problem but none have worked.
Some of my device info is here if its needed:
Model number: GT-I9100
Android version: 4.0.4
Baseband version: I9100MUGKG2
Kernal version: 3.0.15-I9100XWLPT-CL941023
Build number: IMM76D.XWLPT
Thanks for any feed back!
UPDATE: Whenever i enter the call settings on the device it won't let me enter call forwarding settings and additional settings, it' comes up with the message: Network or SIM card error.
Afternoon all.
I need some help. I have been searching forums all day trying to find a solution to my problem, but I'm just getting more confused. So please, if there is someone out there that can help, I would be grateful.
Bit of background. Yesterday, my phone was working correctly and when I went to make a call later in the day I had no network. When I tried to check the network settings, it stated "Insert SIM card to access network services".
When I checked Settings>About device the Baseband version is listed at "Unknown"
I read somewhere to try *#06#, which I did and it shows IMEI/MEID "null / null"
My phone is a Galaxy S2 GT-I9100 on UK Vodafone network, the rest of the phone info is as follows:
Android version: 4.1.2
Baseband version: Unknown
Kernel Version: 3.0.31 - 462349 [email protected] - 111 #3 SMP PREEMPT Tue Nov 6 02:42:23 KST 2023
Build Number: JZO54K.I9100XXlSJ
I have already tried the following:
1. Removed battery, waited 10 minutes, rebooted - Failed.
2. Wiped data and factory reset - Failed.
3. Installed a completely new version of 4.1.2 from HERE - Failed.
4. I have also tried my SIM card in my misses GT-I9100 and it works fine, so it's a handset issue.
I am at a loss of what else to try.
Can ANYONE help me, please!!!
Thanks in anticipation.
Pete.
If you've never 'messed with' the phone (rooted it or run non-stock firmware), send it in for warranty service if your warranty is still good. Trying something that could potentially bork that warranty & end up costing you money isn't worth it, and there's a fair chance they wouldn't work anyway unless you had an EFS backup which you wouldn't have if you've never rooted your phone.

The rom you linked to is the older leaked pre-public version of Sammy JB. You should try flashing the latest final public version from here.
You need to flash another modem ... Tell me if it works or not
Or try this

Hello everyone. Today I was in the middle of sms conversation and suddenly I realised that my phone lost it's ability to send messages as well as calling/receving calls.
Here is info about my phone:
Model/firmware:
Currently flashed rom: I9070XXLQB_I9070OXXLQB_HOME.tar.md5
Model number: GT-I9070
Android version: 4.1.2
Baseband version: I9070XXLQB
Kernel version: 3.0.31-66490; [email protected] #2; SMP PREEMPT Tue Feb 15:52:28; KST 2013
Build number: JZQ54K.I9070XXLQB
Network information:
Network: T-Mobile.pl
Signal strenght: -79 dBm 17 asu
Mobile network type: EDGE
Servise state: In service
Mobile network state: Connected
My phone number: unknown
Offline mode is obviously off.
APN matches network.
*#06# shows correct IMEI.
I searched an answer on xda and did everything that you advised (flashing another rom, factory resets, swapping SIM card, removing battery for 15 mins, etc.). Only thing that I haven't done is flashing modem, because I don't know if I can flash it on i9070.
Ask anything, I propably forgot to tell you about something.
Bump.
Please help me guys, I'm very desperate.
Is the phone number unknown so you won't display it in forum ? I wouldn't think it should say unkown. Also, maybe check the smsc number and make sure its right.

Try flashing modem.bin or whole new firmware once again of Samsung through Odin...hope it helps you...
@custom-tisto
It literally says unknown. SMSC number is also correct.
@Shrihari007
I had tested few roms from sammobile.com. It didn't help
And just to make it clear- phone works perfectly fine, except of any sort of "phone" service. I'm worried that it could mean some kind of hardware problem
Hi there
Hopefully someone can help me I broke the screen on my Samsung galaxy SIII i9300.

Dids your baseband and imei disappear as a result of you repairing the screen ? Have you tried to flash a stock rom via odin?
