[Q] LG Optimus Black internet problem

Well recently i bought a LG Optimus Black, at the begining internet and all worked just fine, and now suddenly i cant connect to internet.
I am able to connect to a wifi network, but 3g wont work, how can i fix this?
Every opptions are right.
I tried the same sim card in Samsung GalaxyS2 and some other phone, it works fine. So it has nothing to do with the SIM.

try to configure your 3g network, look for it on the internet.
i only had this problem when i install NOVA ROM, but it was easy to solve the problem.

I have tried but not helping.

Is it running on Stock ROM or NOVA?
Just like lucasmalaguti said, this problem happens only on custom ROMS.
Anyway, just check your settings.
Settings > Wireless & Network > Mobile Network > Access Point Names
Search on the internet or ask your provider for the setting configuration.
Also, if you have a few Access points, Eg. MobileInternet1 & MobileInternet2, make sure the right one is checked.
Download APN Backup & Restore app from market to delete and re-add Access Point.
Once edited/add, reboot phone for changes to take effect.

Check your APN settings
Sent from my LG-P970

I'm running a stock V10E ROM
My APN settings are OK (sent from my provider)
Tried to manually add it, but nothing helps

Today i called LG Service support.
They say that i am not the only one with this problem.
The problem seems to be caused by automatic software update (V10A => V10E).
Only solution is to reflash ROM.
So i did that and now everything works fine.
Thank you all for trying to help!

I have same problem, how do i re-flash to the old fw
Hi, I got same problem please tell me how can i re-flash my previos fw? thanks.

Hello! I'm newbie
I have the same problem. Please help! What is this ROM? How can I do this? Can this really fix my internet problem? thank you

Had same issue, thought it was the carrier but it could be the phone, hope this helps
1. turn off your OB and take the sim off
2. test the sim's 3g on some other phone
If it's working
3. put it back in your OB = problem solved
It it's not working
3. call your service provider

Same problem in cyanmobile. I found way around it by creating one more apn that is a copy of the first and then I did some small changes like authentication type and apn type to default,internet and Chandler the name then I set Apn as the modded apn sometimes the connection starts if it doesn't I just switch back to original and voila the connection flashes for a sec and is back.

As I said just follow my method or do a factory reset after booting the phone. Then manually configure your apn that is a big I have faced in all cm roms. Try it both worked for me.

[Q] i8190n no network on any 4.2.2 rom

Hi all, I've been trawling through the forums for over a day trying to fix my problem of no mobile network on any of the 4.2.2 based roms,
I can see my imei no, baseband (I8190NXXAMD3) etc. However my network is "unknown:0", signal strength "0dbm 99asu" and the rom doesn't see my phone number,
I have, flashed + reflashed with wipes of data cache and dalvik.
Checked my APN settings (default is ok, though on initial boot isn't selected) [also reentering my apn settings and clicking save seems to delete my APN(s)].
I have disabled wifi + gps etc, aeroplane mode on+off several times, many reboots etc. ( i have noticed that on first boot the mobile data tile(toggle switch) says "no service" and the signal indicator is shown in the status/notification bar [empty, no signal], but after enabling then disabling aeroplane mode it changes to "emergency calls only" and the signal indicator icon disappears from the top right,
I have tried Maclaws 4.2.2 releases (aokp,cm10.1,PAC) and Team Golden's releases (including the latest ParanoidAndroid 3.69) all have no mobile network issue ass described.
I also found a modified build.prop on one of the other threads (for aokp) and imported it over the one i had, made no difference
the only thing i haven't done is flash via odin, all flashes are performed from the latest CWM (not trusting this laptop atm)
DModv6 is working fine for now, but i'd really like to update to one of the 4.2.2 releases, developers doing a great job bringing it to the s3 mini =D
If there is anything else i can do to assist in fixing this issue please don't hesitate to ask me.

flash official firmware of your region >root>use csc changer to change csc >then follow instruction to install 4.2.2 rom , i think the CSC is the problem .
TRY PACMAN(team golden)

CSC is not the problem here. CM-based roms doesn't even use it.
You're not the only one with this problem. I've seen a few more with same issue.
Anyway..you should really try to flash a stock firmware using odin to see if everything is working ok, not only on dmod.

Yes thanks, tried that (as i said) =]
still waiting for a good opportunity to reflash stock with odin. Hopefully might solve some of the random "front end" crashes i get.
i will update the thread as i have flashed and if any other revelations come to light.
Thanks for all the help here at xda =D

flashed...
ok so i downloaded firmware - I8190NXXALL6_H3GALL2_UK_H3G_Android_4.1.2.zip
and flashed with odin, log stated no errors, but stuck in a boot loop. (on first boot cwm asks to install unsigned package, clicked yes, restart, then stuck on samsung loading screen)
Reflashed maclaw studios latest aokp release just to test,inc factory reset and dalvik wipe ofc, but still no network =[ (checked APN, aeroplane mode on/off etc)
also back to baseband ALL6 instead of AMD3 now
Restored backup to DMod6 (still got ALL6 baseband) and everything working again.
Just wish i could get 4.2.2 working with network...
Any ideas?
thanks
* Also thought that firmware should have had the H3G logo for boot animation, not samsung.. bit odd =]

Any help?
Anyone had any similar problems, and managed to overcome them?
Or can anyone point me to any tuts/guides so i can maybe fix the problem myself, whether it be "splicing" 2 ROM's or whatever.

Buddy believe me I tried it out with Maclaw's CM10.1 and I don't know why but I had the exact same problem than you so my only solution was to test it again with stock rom and later with Dmod v6 too check everything was all right againg and my issue was fixed, hope to help you in something and find out a solution for your problem.

Cm10.1 - no network
Flash stock - all working
Flash Dmod6 - all working
Flash Cm10.1 again - working network.

Ok thanks for your input,
Well i tried latest CM10.1 already (big thanks to the maclaw team) but still no network, currently on ALL6 baseband, same issues as previously, no network, presuming sim drivers not working properly for me as it doesnt show my number.
Any1 got a link to somewhere with a list of available Modem files (different basebands) ready for download?

new Version available already,

Solution
Dear Sheephog,
Did you find a solution for this? I'm having a very similar problem with CM11 on i8190n. On Touchwiz, mobile network and data are fine. But when I install Maclaw's latest CM11 build (whether using clockworkmod or TWRP), factory reset, then reboot, CM11 boots up nicely /except/ mobile network and data are unknown. Network Operators (in Settings>Wireless and networks>Mobile Network Settings) yields "Error while searching for networks". A restore to Touchwiz gets mobile network and data back no problem.
(My baseband version is I8190NXXAMJ2.)
Thanks

"could not send" SMS-error

well i got a new problem here.
so basically, i can't write any SMS. That problem occured after I installed the SLiM-rom. Now I can't write any SMS anymore (using the Stock Messaging App). It always tells me that "could not send" error... I've tried google messaging, didn't work either. But calling does work for some reason.
anyone knowing how to solve that problem?
#edit: I just tried entering an USSD code, it tells me that i no connection or invalid mmi code.

I ran into that problem as well after going through a few roms. I think the issues is not doing a full wipe/erasing user data before flashing. That should fix it.

Isn't there any other way to solve that problem? If anyone needs the logcat to spot the problem (and there are some errors, I just don't know what they mean), I can give it to you.

Hey!
I had the same error, also with SLiM Rom. Sadly, I can only confirm, what Nurmi already said, after a full wipe of data I was able to send SMS again. Trying to restore my data partition which i backuped via TWRP before i started troubleshooting, led to loss of SMS function again. Some people said, the problem could be PRFC 1.0 and lower. However, if you don't want to do a full wipe, try messaging app signal. It can also be used to send SMS and worked in my case, whereas stock messaging ap as well as hangouts didn't. Only problem here ist, that in Ultra stamina you can't send SMS either, because you can only use stock apps.
Hope I could help you.
Cheers!

So basically, I have to reflash the ROM fully with Wipe Data + Cache + Dalvik?
Kinda sucks, hopefully this problem gets sorted out somehow

As I said, you could try Signal for SMS messaging, but you still won't be able to send SMS in ultra stamina
Edit: also, I can neither confirm, nor deny that the problem is caused by Slim ROM itself

I faced this issue as well, but i did not use any custom roms. I have a UK Z3C and i had flashed the latest US rom. I was able to fix the issue by downloading the UK rom and flashing it again. It could be the US rom on a UK phone problem. I downloaded the ftf using xperifirm from flashtool and flashed them.

I faced this problem with prerooted CE1. I have no solution for now

First install any other messaging app from play store then make it default messaging app. After that open Sony messaging again and make Sony default messaging app again. This should solve the problem.

I do it the same . factory reset on .264 i dont lose my root. I restore all apps and data by titanium backup and sms working now . I change firmware many times from 4.4 and newer meet this problem before it was first time.

Still can't send sms
I hope someone can help, I updated from 4.4 to 5.1.1. Now I can't send sms, I can receive sms and mms and make and receive phone calls as well use the internet.
I've flashed back to 4.4, factory reset (wiped), pc companion phone repaired, reset phone again and updated to 5.1.1 again, tried textra, signal, hangouts and stock app. But I can't send a text. I've read about rooting and using other programs but I think it is a bit beyond my scope. Any other suggestions would be much appreciated. , it's not the sim , I've tried it in another phone and it works fine too.
Edit: I have a D5833 on telechoice in Australia.

Working out out slowly
Ok, so I got a hold of another phone today, it appears my provider (Telechoice,Australia ) may be at fault. I put a different sim card in my phone and it all worked as advertised, put my sim card in another phone and I get the same issues. Worst part is, is that this is the 2nd sim card now..
So what might cause 2 sim cards to fail with the exact same issues??
