My internet data frequently disconnected

Hello,
i am back again with a new problem!
All the previous problems that was mentioned in this forum is GONE. i was a happy owner. Until i got this problem.
so i wanted to try new Modem, just so i can increase my Signal, and right now, my data plan is keep going on and off, and most the time i can't get it connected it.
i did the wipe date /factory reset from the ROM manager, and wipe cache and dalvik. and yet the problem is not solved.
right now, am running cm-10.1-20130304-EXPERIMENTAL
and the Modem am currently running which sometimes works ( I747MVLDLK4 ) am with Rogers, Canada, Edmonton, AB
If anyone helped me out with this, your next coffee is on me! for real!

anyone?

When I have Wifi or Signal/Data issues, I just Odin back to stock and then re-root & flash ROM again. Works every time.

Did you use ODIN to flash the stock ROM and factory reset in stock recovery ?

Yes! i think i did a mistake. While i restored to the stock rom, The baseband that i was using it was I747MVLDLK4 and not the STOCK modem. So maybe that is why its not getting connected? am trying to apply the stock modem into the the stock rom, but its giving me Fail error.
am just scratching my head right now to be quite honest and this close to throw my cellphone outside of the balcony.

What type of fail error?
How are you trying to flash it?

i managed to make my modem into the stock version. However am just getting "E" in my data connection. Reminder am still in STOCK ROM and stock modem now. is that a good sign that i slighty getting everything back??
should i just install the CM 10.1 now and see the results or what you guys recommend?

annnnnnnnnd my " E" is gone.. Beautiful
do you guys think it might be a actual physical sim card issue?

UPDATE: i restored my phone into the stock rom by Odin3 and now i just re flashed the Cm 10.1 again. sadly i still have no connection and my income and outcome for calling and texts is also not working.
please help!

Try flashing Task's AOKP and see if you have the same issue. Additionally, try deleting the current APNs (access point names) and manually enter the APN settings for your carrier. Could also just be a faulty SIM card as you mentioned.

"No service"

Hello
I have LG G3 the international version with installed stock rom 5.0,
Before I install it, I backed up the previous kitkat rom.. When I installed the lollipop stock rom I decided to go back to my previous kitkat rom. After restoring it and booted it everything was ok but it says no service, emergency calls only. And the signal at the status bar was refreshing every second automatically. I tried to return to that lollipop rom to see whether the signal is ok or no but there was no problem with it. But I dont know whats the probkem in that kitkat rom.... Plzzzz helpppp mee!!

I have the same problem! I used a custom lollipop rom and messed with something so I had to restore the stock Kitkat.
Now it keeps searching for the signal and says "no service" It found the signal for a few times but lost it immidiately.. Wifi works fine.
i would be rly thankful if somebody can fix this.

( i repair phones myself actually as part of my job but never run into this)
Ive flashed back to stock from via XDA instructions
Any help would be awesome!!
Thanks

I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!

Same happening with me,
I have LG G3 T-Mobile version, it keeps searching the service, sometimes it finds when there is very good signal, or when I am too close to the GSM antenna, I was thinking maiby there is problem with antenna contact, I have opened cleaned, but with no success. When is has service it does everything, calling, sms, 4G.
any help with this issue?

HI. i tried to change to several radio but I still don't have a signal. I just can't find the thread from other site, that it could be a D850 not an D855 motherboard. He tried to change the ROM to D850 and finally got a signal.

I have the same problem, any help is welcomed.

If you can, return the phone. As previous post suggested, its a popular thing from some chinese sellers to change the model. You will see the original model in your motherboard (you have to disassemble the phone) and have to flash the proper stock image. First confirm that the model is the model you ordered.

The phone was okay, this started happening when I flashed stock Marshmallow, then I flashed MIUI KitKat rom to see if its the the marshmallow that does that only, but it was on MIUI as well, after that I flashed Fulmics, but still the same. Now I'm on stock Marshmallow and it's doing it as well. I found a little "thing", when you set the network type to WCDMA/GSM there is no more no service, everything works. But when you put LTE it goes down.

If you suspect this can be the case of model tempering by seller, open your phone and unscrew the upper plastic cover, at the right you will see the Motherboard factory code with the phone model in it. Youll have to flash an according complete stock with flash tool.

and from where i can find japanese version of lg g3 sock firmware?

[Q] disappeared LTE all firmware

What is done:
first I flash 30B bump, the problems starte. then flash 30B LGUp, flash 21a and 21c, change band in ingeneering menu, delete lteconfig, flash 30b bump with modems: 21a, 21c, 30b hybrid, change of operator, manual config APN, manual search network. All this does not help.
Any ideas?

no ideas?

Idem.
But after reboot 4G is ok, but again...every morning i lost signal 4G...only 2G/3G is ok. So..reboot & 4G is up......disappointed.

Same on my G3. I downgrade from MM to LP but problem persist.

Same here....tried rollback to kitkat stock, LP stock, CM12, Cm13, and some other roms with no luck....have just flashed stock LP for repair...

so today I tried swapping my SIM with my friend's
he is using G3 with stock 21A, and his SIM is of the same carrier as mine
after swapping, I found that my phone (and of course his phone, too) is working normally
my phone is normal even after swapping back
did some different tests like switching on and off with 3G, LTE etc., everything is normal, at least at this moment

Still working with you? So it is sim card fault? With me after searching networks everything seems to be ok, but I couldn't connect with LTE. Only sometimes successfull connection.(once a day and after reboot same...) Very strange. :/

I lost network signal randomly... i tried with 30b hybrid modem, 21a, 21c... kdz method, twrp bumped rom... and doesnt help me at all.. my network signal gets a rotating circle randomly... and in that time my phone is out of coverage... it is .... hundred times in a day... i dont know what to do, please help

same here when i use sucks 30b D855, but now everything is ok with me.
Steps that have been followed:
downgrade to lollipop 5.0
install CandySIX Rom , then try to connect to my carrier network , at the first time it not give me anything , but when i reboot my phone , LTE appears and everything fine
back to CloudyG3 2.5 then i found that the problem resolved
My phone now works well

OKAY, i found a solution to the problem and here is what i found :
Pacote-san said:
Same here...
Edited: Fixed this deletings the folder LTEconfigs on System/app
Had to then configure it to auto GSM/WCDMA then switch back to LTE auto
It connected at first with 3g then it went LTE and worked normally

Some people got their phones back to normal by flashing some roms (like CM, ACIP, stock, etc.), but that didn't work for mine
not sure if it was sim card fault, but my problem solved (at that time i was back to LP stock 20h) after swapping my sim cards with my friend's.
i am still using that sim card at this moment, working fine since last thursday

Same problem here, have signal drops on MM roms with LTE connection.
Tried all methods above, nothing really helps .. ;((
The signal is fine on LP roms, tho i installed N&N so i was able to change network type to GSM/WCDMA auto, having steady signal now, but missing LTE speed, trying to find solution to fix this, but unfortunately for now.

Same, my G3 doesn't recognize my sim sometimes or it just loses signal randomly, making the smartphone almost useless.
I tried CloudyG3 2.5 Lollipop, then upgrading to Marshmallow with many radios flashed (also the hybrid one) , then I tried to come back to a stock Lollipop ROM and the signal is always unstable. I'm going crazy due to that. I'm starting to lose hope too.

I think I've tried every possible solution to the connectivity problems I've read since flashing 30b.
Freezing LteConfigs gave me more stability, but didn't solve the problem completely. Tried editing the build.prop to force LTE as preferred network type, this didn't change anything. Don't even know how many times I've changed my apn settings.
Tried every combination of modems possible: 21a/c modem with 30b rpm/tz, pure 21a/c, pure brazilian 20c, brazilian 20c with 30b rpm/tz and nothing. Changed sims multiple times, didn't work.
The only way to get a reliable connection is to limit the phone to 3G... but that isn't a solution since I pay for unlimited 4G. If I let the phone in auto mode, the instant it tries to connect I lose all connectivity and it would take up to 2 minutes searching for the network.
I'll flash the stock rom today and if it doesn't work I can safely say it should be a hardware problem.

I had exactly the same problems I tried all of the solutions mentioned modems/roms/etc but what solved it for me was flashing the Pure stock MM kdz now no signal drops or 4g problems.

Did you root after flashing the kdz? I'll try with pure 30B but having no root is almost as bad as no 4G.

No not rooted it yet, to be honest I don't like the kingroot app it looks way too suspicious to me + the rom is smooth and stable at the moment so I thought I would stick with stock for a while.

LG G3 4G Network Drops

So the problem I'm having with my G3 is that the Network either drops and comes back repeatedly or completely drops and does not return. This only happens on 4G. When I go into network settings and change network mode to 3G it works fine and I get a constant signal all the time.
I have been using Fulmics ROM and I thought maybe that was the issue. But it wasn't.
I tried 3 different sims from three different carriers (Three, EE, O2) on several stock firmwares. (20N, 21C, 30A, 30F).
Each scenario is the same; network drops when phone is on 4G network mode, but its fine on 3G mode.
However, I have noticed that if I leave Wifi OFF allowing 4G data to connect first, then its fine. I can even turn Wifi ON again and the network is stable. I can even turn Wifi and Data OFF and the network is still stable.
But, if I toggle aeroplane mode, where Wifi connects first or where Wifi and Data is turned OFF; I am back to the network dropping.
Also, I live in London UK so there should not be any signal issues. Can anyone tell me why this is happening. I doubt it's software issue as I've tried several firmwares.
Any help is appreciated.

Mate I'm afraid there is a high possibility it's the Fulmics ROM.. I'm still trying to read up on the issue myslef, there's a ton of reports in the Fulmics thread and around.

I'm using an UK bought LG G3 as well (from Three) and started experiencing similiar issues after I flashed Fulmics. Even tried rolling back to 4.4.2 using a .tot file but didn't really help me.
Still scouring all around trying to find how to fix the issue..

Hmmm looking back now this issue did start when I first installed fulmics 3.5. But shouldn't everything revert back to stock when you reinstall stock firmware.

That's what I thought but I guess it's a little bit more tricky.
Anyways I think I managed to restore some kind of stability in the signal, still unsure about the process though. Seems that different stuff are working for different people. In a few days I hope to have some information to give you how to fix it.
In the meantime try checking the Fulmics thread for ideas and suggestions (that's where I start off from).

Yeah let me know when you find a fix. Really appreciate the help.
One thing that is sort of a temporary fix for me, works on Three, EE and O2 (only ones i tried), is connecting Data first when on 4G mode.
So if I toggle airplane mode and if Wifi connects first then the network drops or keeps refreshing.
But, if I leave Wifi OFF and Data establishes a connection; the network is stable and I can then turn Wifi On again and the network will remain stable.
I just have to make sure the network does not lose connection (i.e. tunnel or airplane mode), and if it does ensure Data connects first.
Also, another thing. After I reinstalled Fulmic 5.3 it seems 4G mode is sort of stable. As in when on 4G mode instead of dropping the network it connects via 3G automatically. But this only happens with Three.

Okay here is what worked for me - open this guide and download the Three specifiic Lollipop and Marshmallow .kdz files.
Flash the stock Marshmallow firmware first using the LG Flash Tool method. Your phone probably won't automatically get recognized since you're running Fulmics now so you'll need to change the COM port as described in post #
After that downgrade to stock Lollipop using the LGUP method. Personally I downloaded more updated (I think, not sure) files from here.
Then I proceeded to re-root and clean install Fulmics 5.1 and the 5.2 and 5.3 OTA updates from recovery. Booted and network works without drops now with 4G connectivity.

I changed my carrier and got an automatic SMS with configuration for my phone and instructions to save it. I should've known something was fishy when I recieved the "congratulations for setting up" message even before I recieved the actual settings. Anyways 4G was running fine on my new carrier with 32 mbps speed which is okay, much better compared to the same carrier 3G network, however I only had 3 bars of connection so I gussed what the heck, I should save that configuration after all, it might make things better. What a bloody mistake. I lost 4G connectivity and my phone refused to connect to the 4G network, only 3G (just as you describe).
What worked for me in this scenario was wiping the cache and dalvik (not really sure this step is even necessary to be honest, but I was headed for a full rom re-wipe anyway and decided to try with this first), going into the hidden menu and choosing LTE only connectivity (Fulmics Tweaks -> Hidden Menu [or the hidden code for the phone app if you decided to stay on stock, which I dont have] -> Modem Protocol -> RAT Selection -> LTE only. At this step my phone got to the usual 3 to 4 bars of connectiviy but was displaying "Emergency mode only" and no data at all. I proceeded to Settings -> Networks -> More -> Mobile Networks -> Access point names -> Reset to default from the menu. If network mode doesn't change back to GSM/WCDMA/LTE auto automatically, change it back manually. At this point I had restored back my 4G connection and everything is working normally (30-32 mbps connection stationary in my house through a wifi hotspot next to my laptop).
Good luck, I would follow the steps as described just in case. I tried many reflashes before that should've worked but didn't for me. However different things work for different people, hope this works for you and please report back

I'd like to thank you so much for this information! I was having signal drop issue after installing Fulmics ROM. Tried to flash stock ROM but no success. After doing the downgrade via LGUP method to LP my phone is getting full signal again (at least I didn't notice any drop until now).
Thank you!

Sorry for the late reply.
I followed your instructions and unfortunately it didn't work. :crying:
I first tried with the D85520f you provided and then with an updated D85521C firmware. But nothing worked.
The temporary fix, which I found works, is to ensure 4G mobile data establishes a connection first before Wifi (turn Wifi OFF then ON after data established). Then there is no signal drop until I go through a tunnel or phone restarts (signal drops completely), which means again i have to ensure 4G mobile data establishes a connection before Wifi or else it'll go back to the constant signal dropping.
Guess I'll just stick with 3G at all times. I've spent too much time trying to correct this than actually finding enjoyment in using the phone.
Anyway really appreciate the time and effort you took to help with this annoying situation. :good::good::good:

I flashed dummies and get dropped 4g data like this.
I have tot back to stock and didn't help... not Kdz
Haven't downgraded yet to LP yet.
On turborom now.
Can I just flash this modem? Have a link to the 21c modem?
Flash in twrp or send via LG flash?

Elephone p8000. I think i messed up bad.

Ok so i got the phone is stock form with android 5.1 and a few bugs common to this phone( screen flicker and poor wifi speed). I read more than a few forum posts that said flashing the rom to various other roms would fix it and this wasn't my first modded phone so i did. I am not too sure these flashes took as android looked and acted the same as well as had some of the elephone software. It did however screw up the phones imei. after a google search i reset the imei. I no longer have the invalid imei message but now i have a big NO SERVICE message. This is the us market phone. I really hope you cant somehow change the frequncy bands by flashing the rom. any help would be awesome.
Ps. the screen still flashes.
edit: ok tookjfer671's advice and flashed the us rom. it killed the imei (again) so i reset the imei. now somehow the imei numbers got on the wrong sim cards. They are backwards. will this affect anything ? they wont reset at all.
Edit 2 I guess you can mark this one as solved. The reflash with the us ROM worked but the backlight still flickers. Not a launcher issue the entire screen goes dark and its random.

Yup, I believe the US version B doesn't have any other alternative custom roms to flash...although you can root. Version A (Asia/Europe) regions have a whole lot of roms to choose from...it would've been nice if we could flash those as well and keep the baseband out of it so we don't lose network connections.
Anyways...I flashed as well a version A rom and found myself with a no connection to my network (everything else worked fine), flashed the link above and got device back to full working order. Hope it helps you out.

i'll give it one more shot. btw did you use flashtools or recovery?

Sorry for late reply...I was rooted with the A version and on TWRP recovery, flashed stock recovery then flashed B version and now on CWM recovery. All using flashtools.
