[Q] CyanogenMod 2G/3G problem. - LG Optimus Black

Hi, I am currently using Mackay's ROM which is CM 10.1 based. Sometimes when I turned on 2G data, it won't connect at all. When I tried switching to 3G, it stays at 2G and nothing happens. When I switched to airplane mode, the data switched to 3G but the signal bar stays full bar on my drop-down menu and there is no signal,aeroplane icons on the top right corner of the phone. The problem also occurs the other way round when i switch from 3G to 2G. The problem is only solved when i reboot my phone, however after another few minutes or so, I have to reboot again for data connection. Does anyone have a permanent solution for this? As it is frustrating to keep rebooting. And i tried changing APNs. The default APN for me is MiWorld WAP (GPRS). However, the default APN does not really connects. It's like a Laptop having a 'Limited Connection' WiFi. So I can only switch between the other 2 APN with is M1 and Sunsuft Internet, which the problem still occurs. Thanks to anyone who replies.
Have a nice day!

Already tried flashing a newer baseband?

Yes, sometimes this happens to me too...but it always did with every CM10/CM10.1-based roms.
I tried many basebands (v20, v28, v30), but it always happens. To me, about twice a week.
I always thought this could be related with the fact that we don't have a baseband made for jelly bean, and so I gave up on this issue.
When it happens, I simply reboot my phone.
And I avoid to use airplane mode, because usually after disabling it (if I left it enabled for more than a few minutes) I can't get network coverage until I reboot.

Thanks for the reply. I will try flashing newer baseband.
//Edit 1 What is the recommended baseband in Singapore? I tested V30B Euro OPEN, but doesn't seem to solve it.
//Edit 2 I read on other threads which says choose the baseband from your region, and i went to download a V30C Singapore version of the firmware and extracted and flashed the baseband. It seems to be working well.

[Q] Wifi disconnects data network after gingerbread update (i9000m)

Used Odin to update to gingerbread from froyo on my i9000m the other day. Theres no service here at home unless I put the phone on the bathroom windowsill, so I didn't notice until today when I went to work that I wasn't getting any data network connection. Could make and receive calls fine, wifi works, but no data, so no browsing or facebook or any apps that require it. I called bell and they came to the conclusion that I have to send the phone in for repairs. Thats a absolute last resort, so I tried another factory reset, this time from the recovery menu. The first time, during set up I enabled wifi, this time on a hunch I did not, and it worked. Also note that the first time, the network connected for a split second before disconnecting again. Anyways, I was getting 3g fine, then I tried wifi, and it disconnected again. Turn off wifi, data comes back. Whats up with this?
Did you set your APN? Go
Settings > Wireless and Network > Mobile Network > APN Names
Then hit menu and add a new APN if none are there. If one is there, it's named something like 'browser' (at least that's what mine is called on my Bell i9000m) and I'm wrong. But I had this problem, and this is how I solved it. You can find the APN settings for your network by google-ing "[Provider] APN Settings]", and if you're on bell you can find them here:
http://support.bell.ca/en-on/Mobili..._Nexus_One_for_the_Bell_Mobility_HSPA_network
It says Nexus One but it works for all phones on bell.
settings are exactly as depicted on the bell site, except the apn was called browser instead of bell. changed that, same thing. other suggestions?
Can you tell me the version of gingerbread you're on, where you got the files, any mods to the firmware like pre rooting?
Sent from my GT-I9000M using XDA App
2.3.3, downloaded from here, no mods.
Alright, so totally stock. What's the version code? It should be UGKG3. Have you tried forcing a kies update with a registry hack? Was it one PDA when you flashed it or 3 files?
Sent from my GT-I9000M using XDA App
Yes, its UGKG3. I flashed with the PDA, PHONE and CSC files. I dont really know what you are talking about with regards to forcing a kies update, if you could explain I'd try it out
This has always happened to me, on Eclair, on Froyo, and now on Gingerbread. Whenever my Wifi is active *and* connected to a network, the Data through HSPA is automatically disconnected.
I always thought it was a battery saving feature - if you have Wifi access, and presumably internet access, then you don't need internet through the cell network, right?
So if you're not getting internet access when your wifi is active and connected, then perhaps it's a problem with your wifi router not passing external internet to your phone?
The thing is nothing changed besides the firmware. wifi worked fine here in the house before and no problems connecting to the data network on the go with wifi enabled. I'm really running out of ideas here.
I guess I misunderstood you before. Are you saying you have no data access at all when wifi is enabled, whether or not you are connected to a wifi network? If that is true, something is definitely wrong. That doesn't happen to me with KG3 - just checked.
Have you tried reflashing the modem file? Maybe it got messed up in your flash before?
Sent from my GT-I9000M using XDA App
yes, no data regardless of wifi connected or not, as long as its enabled.
which is the modem file?
just an update, this seems to have mysteriously fixed itself.

Data doesn't work after changing to 2g or 3g

Does anyone know a solution for this annoying problem? After switching 2G to 3G or vica versa the internet will not work, shows 2G or 3G connectivity but the upload and download arrows never come up and there's no connection.
thanks

restart?
maybe that's help.
also, wipe cache from recovery.

I restart my phone 5-6 times a day, I install new kernels often so cache clearing doesn't appear to help.. im thinking its some kernel related bug but it happens on Neoblaze and Horsepower.
Sent from my LG-P990 using Tapatalk
I'm having the same problem. After flashing HP RC 4 (or so) kernel, mobile connection just doesn't work at all, either 2g or 3g. I tried flashing cm7 (from Topo) to see if the problem is with the ROM, but it still doesn't work.
Since I mostly use wifi, I didn't notice when it stopped working, plus I usually disable mobile data. Haven't tried flashing another kernel though :/

[Q] CM10 and no connection to internet

Hello all,
I flashed CM10.0 a few weeks ago and everything was working fine up until 2 days ago, now my I9000 won't connect to the internet at all. I was using Easy Battery Saver which cancels the data signal everytime the phone is idle, but this stopped turning the connection on. I uninstalled it hoping the phone would revert back to normal but can't get connected. I restored the app hoping it would pick up the settings again but still no joy.
I have wiped everything including user data and the caches, done a factory reset and reflashed the rom. The signal did return for about 30 minutes after the flash but the connection has since died again. I've tried switching on the roaming and national roaming, also no luck.
Does anyone have any idea what might be causing this or even how to fix it?
Thanks in advance

I am just guessing, but as from what I understand you uninstalled the application when you were not having the internet connection working. Right? The correct settings have possibly remained overwritten (some applications block the outgoing data traffic by changing the connection settings). Give APNDroid a try and if unsuccessful try going to your phone operator webpages and find the correct connection settings.
I am using CM10 with APNDroid which works fine. However sometimes I cannot connect to 3G as well. Switching the APNDroid on/off couple of times or rebooting solves the issue.

Thanks for the response mate. You guessed right, APNDroid hasn't fixed it and I haven't been able to find APN settings other than the one that is already in my phone. Might reverting to stock solve the issue? My contract is up at the end of the month so I could handle living with GB until then .
Hi again, reverting back will definitely not solve the issue. From what you had said I understand that the internet settings are somewhat messed up.
These settings are bound to your SIM card. By up/downgrading ROM these remain.
Could you check if your APN settings are correct (I assume you need to check with your provider).
Good luck and keep us informed.

Just found the APN settings online. Reset my APN and it looks to be working. I'll keep an eye on it just in case but I think either the ROM or the App messed up the user/password on the APN.
Hopefully it's all fixed. Thanks for all the help.
first try apn tweaker from market then if no luck what worked for me

[Q] Droid 4 + JB = Phone or Data - pick one?

I have a Droid 4 with stock 4.0.4 that works perfectly with Polish Orange operator (GSM). I tried to install some JB rom, but when I go to 4.1 or 4.2 I don't have any data connection. At first I thought it was a problem in some particular ROM, so I tried almost all 4.1/4.2 builds I could find on the internet. They all have different options, more or less, but I didn't get data connection on any of them.
The second try was to modify 'something' in build.prop. I had no idea how to start so I checked some tutorials and xda topics and I looked at any options that could be related to data connection. After many tries I started to think that it's just impossible, but then I got the setup with working data , unfortunately the phone application started to hang or FC on all phone connections.
The next thing I could do was to narrow it down. I tried some combinations of build.prop, apns-conf, restarts and wiping and I've found a single setting that changes everything - "telephony.lteOnCdmaDevice". It seems to work this way:
1. Just after the installation of any ROM the option is set to 1. You can make and receive calls and SMS's. Wifi, GPS, etc. works. But regardless of what network options I use, if it's LTE or just 2G GSM, what APNs I set, if I reboot or use airplane mode - there are no data at all.
2. When I change this setting to 0 and reboot I immediatelly get the data connection. I don't even need to set-up APN (In fact it works even with VZW default APN, and I'm on Orange PL). It works on 2G and 3G, on GSM and LTE, I get all networks from Edge to HSDPA. So the phone is able to get data connection. But when I try to make a call the phone app hangs, and when I receive one it FCs.
For both of those cases I tried many different configuration options, with reboots, wipes and so on, to make sure that connection depends on build.prop setting and not on anything else.
So at this point I know that the phone is able to do both connection types, but how to get them at the same time?
BTW: I know about using Google, forum search and so on, I tried to find any clue about resolving this on my own but now I'm just stuck. However I've found something that I didn't find anywhere else, so maybe with your help we'll find some solution .
Ok LTE only works with verizon and apn depends on your network
I'am use a mod I flash thet after rom install and this mod patch the build.prob an add a larg apn list
So only flash the mod an have fun

Thanks for saving my phone @NighPlayer32 . I still got some random shutdown so I need to test it more, before I use it as daily device, but now I see light in this tunnel. The phone and data works, even without any touch in settings.
I'm going to check this mod in more details and understand what it does, so I may get back with some more questions .
Thanks

Strange network issue with V409N (Korean V40)

I recently bought an used LG V40 but faced with strange problem. First it connect to network and shows LTE (if data is on) but suddenly network is lost then it search and connect again and again and again . . . usually in a few seconds interval.
Also same happens to WiFi network at the same time but if I put the phone in Airplane mode its WiFi keeps alive.
I've noticed the firmware was belong to KT operator so cross flashed an open Korean firmware (V409NO20h instead of V409N20h) so now I have LG logo instead of KT logo at startup but still that problem exist.
While trying different conditions noticed if I toggle Airplane mode twice the network become stable until next reboot!
Do you have any idea what's going wrong?
I have the same problem with my device (LM-V405EB)! I don't have the problem with the WiFi though, and the only way for me to get a stable connection, is by restarting my device. Turning on airplane mode doesn't fix it for me. Sometimes I don't have any data connection at all, even though my data is on. I'll have to restart again, to connect to data. I have the November security patch, but this happened before I got the update.
I really hope that there is a way to fix this, because it's very frustrating, especially when I need to use my data quickly.

Where do you use this phone? it seems the region is South Africa, so did you try to cross flash your own region firmware?
In my phone it seems that's a modem problem!

It is the South African version, which is where I'm from. I'm using the same carrier I purchased the device from, so I shouldn't be having any issues. I've also had my network resynced by my carrier, so I'm not sure what else can be done to fix it, if even a factory reset didn't help.

My APN settings are correct, as I am able to use data. It's just that when I have my WiFi on for a long time, my data connection refuses to connect, until I restart my device.
A network reset, factory reset, APN reset, and avnetwork resync via my carrier, were all tried and none of those worked.
I'm convinced it's a software bug [emoji2370]
