[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

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

[Q] cyanogenmod 9 - V2+Alfs = Network Problem

After installtion of ROM (without installing other APPS for ROM) mobile network was working fine and I was able to make/receive calls. I used it for couple of hrs, the only thing I noticed that I was not able to turn the WIFI on I thought this could be because of other apps so I installed other apps. Immediately after installing other apps network is gone even if I try to search network manually it says "Error while serching network" and still I can not turn my WIFI on. Any one else having same problem?
I reinstalled ROM to check this and again same problem. No network & No WIFI.

About wifi, it's said in the first post that it only works with static ip, although there's a fix for that, so i used it and my wifi is excellent now.
About the network, i really can't help you but mine is fine...Have you tried to wipe data before installing the rom again?

This ROM need nAa11 kernel to work ot of the box! Why you need alf's kernel?

I have a similar issue.. but only when I use a Stock Rom..
When I use a CyanogenMod based rom I connect normally.
Any suggestion if there's an option, in build.prop maybe, so I can fix this in a stock rom?

hi, you use a rom from XDA? is it happen after flashing a new rom, first boot, no mobile internet? -> how about some informations about runnign system etc. pp. was it working before with same rom? and so on....
if no internet after first boot: turn on wifi, go Settings/Xperia/Internet Settings , and try download the settings with wifi. how that?
second thought: your provider's fault?

Xperia V is not officially supported by my carrier, but I can use mobile data on cyanogenmod.
I tried to add APN for my carrier, but they don't appear, using APN Manager I could see and try to apply them, only to get an error.
I was willing to go back to stock rom 'cause I wanted to use sony's camera.. but mobile data is essential.. guess I'll to stick with cyanogenmod..

i have added my provider (three uk) network apn manually and it worked.. yesterday.. Now still I cant connect. No reaction at all. I've downloaded settings via wifi and didnt help. Im running official rom 9.1.A.1.141. It is not a provider fault - I used o2 before and it was the same problem. Sometimes restart helps. but not now,
edit. now restart helped.. i dont get it.. This is very enoying

Anyone have any ideia how to fix this issue?
In CM all APN are shown correctly, in any stock based rom I can't add any entries, or it's not shown.

[Q] Xperia Z c6603 Sim card not detecting problem

Hello Friends,
I am sorry to create this thread if already a discussion going on under the same topic( I am that much frustrated as well as desperate). I updated my set to 10.5.1.A.0.292 few weeks back & when it reboot I get a popup window saying nfc firmware update error 000004 which is present till the date. Then it starts a new issue like loosing the signal and reinserting the sim card rectifies the issues at first. Few days back it completely lost the signal & a sign appeared on top right corner like a red "X' mark with sim card.I tried to reinsert the sim and when I does the set shows 'sim card inserted , restarting' but after reboot again no signal, when i removes the sim again it popup as 'sim card removed, restarting'.
I tried many other sim cards. Result is same though all are working in other phone. I tried every thing starting from factory reset to flashing using PCC as well as Flash tool but still the problem persist. When I flashed CM 11 and searched the set shows all the available networks ( Though no signal was showing in status bar) but fails to register in any of them. Any idea what happened to my set and is it curable. Please help it doesn't have warranty.

does it work for CM11? maybe there is something wrong with your hardware, check what does it display on baseband, maybe try a reflash once again.

Hello Zennis thanks for the reply. I tinstalled cm 11 on it and then also there is no signal bar in the status bar but under mobile operator option i was able to check the network and all the available network were showing there but when i tried to connect my service provider it failed. I dont think there is a hardware problem coz i use it that much careful and hardly 5 minutes before this issue i attended a call.
Looking forward for your valuable reply.

I think its a baseband problem.... I previously faced problem like no signal,no imei,no wifi, etc...then i flashed different version of stock .ftf
And my problem was solved.

Hi puneet its sad to know that you too are in same situation. As I said in my post the unit was functioning for about several weeks and suddenly it fell into no network state again and this time all my trials went vain. I just sold that unit at a cheaper price to a mobile repairing shop. i dont know what they have done with it. In my opinion dont waste your energy for xperia crap.
Thank you & sorry that i cant help you.

[HELP] Wi-Fi problem after mm update- SM_9208

My note 5 is the duos version, imported in Romania from Taiwan (SM_9208) After updating to Marshmallow yesterday, everything worked fine except for on thing: it doesn't find my Wi-Fi network from home anymore and the only way I can connect to it is by going to,, add network " and manually inserting the ssid and PASSWORD because it doesn't appear on the available networks list. Thst means that every time I turn my wireless off and then on, I have to repeat that process.
I haven't had the chance to try any other WiFi network, but I tried with other phones to connect to the network and they found it and connected to it without any problem. Furthermore, any third party app like WiFi analyser is able to see the network.
Do you guys have any idea how I could possibly solve this?
Thank you and have a wonderful day!

Try to backup your phone and then do a factory reset.

I factory reset after update OTA and everything work perfect.

uhm... does n9208 has update for MM already? if you have links kindly share tnx in advance

I tried doing the factory reset and it still has that problem.
And I did receive the update yesterday through OTA.
Other suggestions? Thank you, guys!

First, try clearing the cache again. If it still does not work, the update may have downloaded improperly so some file are corrupted. It will continue to use the same corrupted files even if you reset. Have your tried flashing the stock Taiwan Rom using Odin?

//LATER EDIT: I finally made it work by simply changing the wireless network's name. For some reason, my phone wouldn't find the network with its default name.
