Network problems with my phone - LG Optimus 2x

I bought my Lg o2x last May (May 2011). I was in canada for 10 months and actually I am from Germany so anyways during canada i rooted my phone and i' ve used several ROMs like NOVA / AOKP or CM7.2. Since I rooted my phone I was not able to call anyone but they could call me and we could text each other. I wondered what the problem was but I am not pretty sure. Baseband? Apn? Right now I am back in Germany I wanna use my phone with my german provider but it is not working. My phone can find a network but not connect.
Baseband: 1035.21_20110725
Thanks )

[Q] GT-i9000 at&t service disconnects often

Hi all,
I recently bought an unlocked international version of samsung galaxy S GT-i9000. I was able to use it with at&t sim card quite happily till now. Even the 3g worked on it. But from yesterday the at&t service keeps disconnecting after using for few hours. The network bars at the top right disappear and a blue disconnected sign appears. I cannot make a call or receive a call till I reboot my phone. In settings->about phone I see that the "Service" shows "Not in Service". When I reboot it gets back to "In Service".
Did anyone face this problem before? Is there any solution for it? My unlocked phone boots with T-mobile preset settings - is this problem because of that?\
Someone please help.
I've been using one on AT&T for quite a while without issue.
Ok. Thats encouraging. Did you change the software on it - like rooting or flashing other ROMS or still using the original touchwiz?
I donno why I am getting this error now..it worked fine last week.

I've flash several roms without issue.
Did you install anything recently before the problems occurred?
I just installed a Yahoo mail application and some online radios yesterday. Nothing on the software side like rooting or flashing. I am still using the samsung touchwiz that came with the device.
Looks like that yahoo mail app is the cause of the problem. Deleted that app 1 day back, and it seems to work smoothly for now without any disconnections. Thanks for pointing out to look at newly installed apps.
did you buy I9000 or I9000M ?
I9000 runs on 900/1900/2100
AT&T runs on 850/1900
I9000M runs on 850/1900/2100

Doesn't really matter I had stock/euro i9000and had no disconnects.. although sometimes I only got edge when there was no 850 3g. I now have i9000m and still get no disconnects.. and yes I am on at&t.

I bought I9000 (not the M version). I am able to get the 3g HSDPA with 1900 frequency. I verified it online before buying the piece that 3g would run on one of the frequencies. The problem I had earlier was not with the 3g network, but with the actual cell phone signal which enables to make calls.

I had this problem for a while after I flashed one of the firmwares.. the fix i think i used was to change the settings on the phone from KOR to BMC.. I forget how to do this..
it was one of the *#1234#* type codes.. Anyone remember?
I guess I was early in thinking everything is alright. The problem started again- it gets disconnected once in a while and I have to restart the mobile. Hey dapoktan, can you please remember what you did earlier to get rid of it? If we change the firmware does it help? I am waiting for samsung's android 2.2 update, hope they at least release it by Nov 11th (as mentioned in one website)

Thanks every one for your suggestions.
Before applying nailer's suggestions, I just saw I could update the firmware to froyo by doing a registry hack in kies http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S_Series#Installing_firmware_for_different_country. So just gave it a try and currently got froyo.
Have been using froyo since yesterday and no recurrence of the problem till now. I also successfully rooted the device following http://samsunggalaxysforums.com/showthread.php/2384-Rooting-FroYo-2.2 and applied Ryanza's lagfix 2.0 available in market. Looks fine for now and the phone runs excellently smooth.

Can't call when 3g is on

I can't make phone calls when 3g is on, with 2g is fine. I went back from miui to cm7 and finally to stock and still i can't call.
Do you think is possible that some hardware failure can lead to this?
More info: changed baseband too, i have this problem also if i change sim
If you changed the BB on your phone then why don't you revert to the previous one and check?
I would not exclude a problem with your carrier's network
I changed the baseband after this problem occured, I tried a different carrier (Vodafone, my carrier is TIM) and calling when 3g is on works
I'm gonna wait if they fix things

Maybe it could be obvious but...Did you try to change Ril by using getrill apk?
Non si sa mai ^_^
Si (Yes)
I tried changing Radio with different basebands but I have the same result, call ended immediately.
Now I'm on Cyanogen 9 and i'm keeping the ril that comes with it.
Calling with 3g works under Vodafone Italy, Tim doesn't.
I've found a post (in Italian) of one guy having the same problem with TIM one month ago, like me he was thinking that the phone was the problem but it wasn't. For this guy the problem got magically solved, probably a TIM fix.
Problem got solved automagically

Hi Electroman!
In O2X you have Baseband and RIL. I believe you can think of these as the antenna drivers/firmware.
When you change a ROM usually this changes the RIL, then it is recommended that you download an app called GetRIL to download a RIL that matches your Baseband.
If you go to Settings -> About Phone you will be able to check what's the version of your baseband.
It is possible to change this baseband. I think the easiest way is by flashing a zip file using CWM, I've never done it because I haven't had any issues with calling or data network or whatever.
Some people claim that some basebands are better with some networks than others, so your call quality might improve if you change baseband, depending on what network provider you have, but then again, I haven't had any issues so I wouldn't know.
I'm almost sure that spica meant RIL, you can change it with an application called "GetRil" from the market, you need a phone with root available ( check the forums for that, it means you can run commands as you were the admin of your machine, unix style).
If that doesn't work i suggest two things: check other carriers with your phone, and check your sim card on other phones. So you can have an idea of what could be the problem.
Thanks again, LarsPT and gasgas. The thing is I haven't changed anything on the phone yet. Everything's still stock. I don't know but this could have something to do with the carrier I think. Maybe I'll give them a call.
It turns out Windmobile doesn't support 2G, and that's why the phone didn't show any signal.

[Q] My Note cannot make/receive phone calls anymore :(

I think my N7000 is broken. Since a couple of days I cannot make or receive phone calls with my SIM card from the carrier 3 (Three Sweden). I've tried two different SIM cards from 3 but it's the same problem. Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up, and if I try to make a call to the phone it's unreachable. My phone is unbranded/unlocked BTW.
I've tested with SIM cards from two other carriers and they both work.
The only think I can think of is that 3G voice calls are somehow broken on my N7000. My carrier only supports 3G and maybe that's what's broken... what do you think? (the other cards I tested also supports 2G and maybe that's the reason they worked, but I'm not sure).
Brgds... /Tubgirl
I think your issue is the same as mine, though to clarify my issue somewhat:
When the phone does this and I try to make a call it doesn't hang up, it kinds of gets stuck and keeps waiting for the back-end to respond. Similarly, trying to send or receive SMS messages doesn't work either. Rebooting fixes this, though it may happen again quite soon or it may take several days to happen again.
I think it is some background-process related to radio operation getting stuck, though I cannot say what causes it. Factory reset and even full reformat and reset had no effect.
I hope ICS fixes the issue.
What I've tried so far is:
Full wipe - No change
Next step will be to visit my carrier store downtown and test yet another SIM card from them. If that doesn't work I guess I'll have to get it repaired.
Oh yes... I tried another card from another carrier (Telenor) and changed Network Mode from "GSM/WCDMA (Auto mode)" to "WCDMA only" and it still worked. So now I'm not sure why it doesn't work on Tre ?!?
/Tubgirl
Update: Got a new SIM card from Three but unfortunately it didn't help. Tomorrow I'll send my phone to get repaired :-(
Brgds... Tubgirl
i got the same problem but is t mobile uk, "Data traffic still works though since I can surf the Internet without problem. When trying to make a phone call it immediately hangs up" I tried others sim vodafone, o2 both work without problem.
Factory reset, different stock roms no help...
Yep, same here. I just downgraded to KK4 stock ROM using Odin and it still didn't help.
Cannot send/receive SMS either.

I guess I have a Galaxy Tab 5.3 now

I have a similar issue, some times i cant call and receaved calls ends few seconds after hanging up.
Sent from my GT-N7000 using XDA
i give up, i changed the network providers to 3 network everythings back to normal.
I can't find the link right now but I read somewhere that there's a hidden area on the phone where IMEI and other carries specific information is stored. As I understand that area is not restored when flashing ROMs. Maybe there's a chance that area has been corrupted??
Brgds... /Tubgirl
In my case , I cannot receive call - I believe it is software issue.
Is there any workaround how to fix it ?

Have you checked that your IMEI is fine (matches the one in the box or the one below the battery)?
i doubt its software issue, i also thought that i was having a software issue, after so many roms that i tried flashing, same result. stock or customized. I went to samsung service center and they had it tested, replaced the board that has to do with the antenna, and now everything is working properly.
same issue i have checked imei with the box and it ok, i can connect to 3G but can't make call only emergency call.
tried CSC Change

the phone is british in italy

Have you guys already tried to use your sims in someone else's phone? Could it be that you have data only plans? Those plans do no allow phone calls even if the device itself can make calls.

[Q] Internet Connection Problem

Hi everybody.. I ordered a Droid 4 from the US (i'm in the UK) .. Setup giffgaff unltimited internet, however for some reason the connection isn't stable. Sometimes the connection will not connect for at least 3 hours. I have rooted and tried the AOPK, Avatar and Liquid ROMs, but its the same issue.
I have another Droid 4 running 4.0.4 and tested if it was a problem with the SIM card, but it worked fine.. No problems what-so-ever.
Any suggestions anyone?

I eventually gave up on giffgaff because of constantly dropped calls, and incoming calls that would go straight to voicemail. Found it a lot better on O2, which is odd given that both use the same network.
For your problem though, how is it if you use the stock ROM? all those 3 ROMs use custom kernels and I haven't had much luck with them on GSM. If it works on stock then you know the problem isn't the phone or the SIM at least.

I have noticed some of your old posts in the GiffGaff Community Forum.
FWIW, I've been using it in anger for just over a month, and can't say I've had any problems (apart from a short outage across the network, which is apparently quite rare).
Cheers,
Steve.

Yea the problem is persistent on the stock ROM too
Is there any way to calibrate the hardware?
Not that I know of, mine just worked.
Did you update to JB yet? I believe there were changes to the radio firmware included.
Other than that, I don't know. If you have an identical Droid 4 that does work with that SIM then the only explanation left would be faulty hardware
Yea it came originally with JB
Can you tell me how to downgrade to 4.0.4 if you don't mind please.

AFAIK - You can't downgrade, I'm afraid.
In the Network Mode, have you selected GSM/UMTS, or are you set to Global?
It does sound like you might have a hardware problem.

Thanks everyone, but I found a solution ~ a very weird one...
I removed all the custom ROMs and safestrap and did a full factory reset on the stock ROM. Miraculously this did the trick strangely enough.

[Q] Problem with data after installing stock JB 4.1.2 EU

Hello, everyone! :laugh:
I'm new on this forums but I want to contribute as much as posible. In this moment I have a question, though; my RAZRi was filled with bloatware from Telcel (my operator in Mexico), so I decided to install a retail stock ROM, specificaly that labeled EU (I also tried with the GB one).
Apparently everything was fine, I even installed the CWM and rooted my phone, but I started to notice that my 3G and HSPA data weren't working. The phone showed the 3G and H+ letters in blue and apparently I had internet, but data is not received at all; the up arrow blinked from time to time but that's it. My WiFi and GPS work as charm.
I'm trying to figure this out because my girlfriend lives in another state and whatsapp is our only link while we're on the street.
Has anyone have the same problem using a stock room from a different country than yours? I'm thinking that it might be a problem with my operator's network because my internet comes back from time to time, but believe me, it's more the time that I don't have internet than the time I do have it, call it a 95 off - 5 on. It's been two days like this and I can't find a solution.
Thank you very much for your help.
Hey Richie,
do you checked the APN ?

It works! And actually I went back to my original stock ROM, just to make sure, and the same thing happens when on 3G/HSPA, no data, but on GSM everything works fine.
I guess that means it's my operator's network, isn't it? I'll have to call and ask them if there's a problem in my area; it's a shame because, in the meantime, I'll have to stay on 2G just to keep my internet working ):
I hope Telcel fix it soon. Thank you very much! :victory:
