[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

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

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] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?

I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.

Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.

I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help

Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?

Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

Loss of 3G connection post ICS stunner 4.5

Hey guys,
i recently rooted and flashed my sgn with ICS stunner 4.5 following the instructions found in these forums. Its been successful apart from the lack of any data connection (3g/H+). I can call and text just fine, but even though I've activated all radios on the euphoria settings no luck...
I searched around and know the solution to be flashing a different modem files, but i do not know which one is suitable: i have an international sgn and im in India if that information is useful.
Thanks in advance

I just flashed 5.0 coming from 4.5 and i have network issues too. i can share my internet data conx via wireless tethering but cannot use the same internet on my galaxy note (host device)..i can call.etc but cant browse the internet or even login into my google account. thr signal icon is GREY in colour instead of BLUE.please help.

Maybe stupid question, but worth a shout. APN settings?

my APN settings are correct,everything was working fine while i was on 4.5 but now on 5.0 the 3G/HSPA mobile data is unusable, like i said yea,i can do wireless tethrering FROM the NOTE to other devices BUT i just can't use my mobile data on the note itself..could it be an issue with something obvious im not seeing? please help guys.

I had audio issues with 4.5 and went back to 4.3. But I did not have issues with my data connection with 4.5. I'm currently enjoying 5.0.
The first post in Stunner mentions that 5 is a major upgrade. To me, that means a complete fresh install is required. I re Odin Mobiled the ICS repack, CWM installed the Stunner 5 zip, entered my broadband APN and reinstalled my apps with Titanium. Sofar, no issues and data is working fine, both wifi and 3G/H/H+.

same problem here, 4.5 H+ with good connection. Here its greyed out with no data whatsoever, just wifi.

@All - Try this-
Try doing a clean install. Start from flashing the cf-repack LP1 through Mobile Odin keeping all the options in Everroot checked. Reboot and let that rom settle. Then reboot in recovery and then wipe cache and data and then flash ICS Stunner 5.0 and immediately after the LP6 modem (with rebooting) Then wipe cache and dalvik and data again and then reboot.
Hope this helps! Hit thanks if you want

Finally. OK. No matter how many times u reboot, it won't work. U have 2 go to settings and mobile networks and see your access points. I had a different one when I was in 4.5 which gave me perfect access to mobile internet network but the one in 5.0 was completely different, all u have to do is revert back to 4.5 copy the access point APN details and then in 5.0 make a new APN with the exact same details. Hope this helps you. Don't forget to use the thanks button

hey guys,to ALL experiencing the same 3G issues/mobile data issues i experienced...this is how i fixed mine.
---> the APN settings i used/had with 4.5 were ''almost'' the same..but i noticed a ''slight'' difference in my APN TYPE. it was changed from ''internet'' to ''default'' (depends on ur network provider though),plus i was using proxy settings while on 4.5 so what i did is NOT to change ANYTHING else in 5.0 APN settings...ONLY deleted the PROXY address and PORT (8080)...saved the updated settings - finito!
so the problem is in APN settings,if you use a proxy as part of the settings just delete the proxy & port,save the settings then u should see the grey signal bar turn blue automatically...i hope this is helpfull to all.

big thanks
king, thanks a lot, your method worked for me very well

[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.

So let me get this straight. Is this what u did?
Cm10.1 - no network
Flash stock - all working
Flash Dmod6 - all working
Flash Cm10.1 again - working network.

I didn't want to try again with Maclaw's rom so I stayed with the Dmod rom with all the features working normally

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?

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
