Have u rooted. Flashed a rom? Is it network unlocked if not on orig device carrier? And if just pirchased are u sure its not black listed?
it is not black listed.
It all began when it started on all the time.
Now it has not started on all the time at 24 hours now.
And I flashed a ROM.
After that, you will not signal more than a few seconds, then you can not register on the network.
Have tried with APN that I know works, but not on this phone can only use wifi.Jag checked with the operator and they have no problems.
Have tried with different SIM cards without result.
my simcard worked with the phone before it started on all the time and I installed a ROM tried olkia rum with the same result.

May have flashed a rom with a incompatible modem. Try using flashtool lgup and going back 100% stock. But be sure to make sure ure not downgrading to a incompatible version or brick could result. Find out what version qfuse ure bootloader is and find stock rom to match.

I live in Bangladesh. Recently I visited Malaysia and bought a Dopod 838 Pro from there. I checked it over there and it worked fine. But after getting back, when I tried the mobile with my country's SIM, it gave a error message saying ' your current network 47001 is not supported, please ask your device vendor for an update' and I got a no service problem. In the available networks section my operator (GrameenPhone) isn't listed.I tried almost everything I could, upgraded to SPL v.7, tried different radio versions, tried different ROMs and modified windows mobile versions like Black version, Pays version etc. The best I got was I got a signal for 2-3 mins. During that time I could make and receive phone calls, it worked fine for that short time. But after that 2-3 mins. the signal drops and the phone starts checking for the signal and eventually I get a no service problem. I tried repeatedly but with the same result. This is so frustrating!!!! I love the phone, how can I make it work?? Hey guys, help me out please. Thanks.

Have you tried to SIM unlock it?? Take a look in the upgrading forum...READ READ READ before doing anything else ok?
Try a different more newer SIM card, or maybe a different provider!
Re:
Tried unlocking, different provider, different SIMs, everything I could think of but alas nothing worked. Any other ideas guys??
Still no luck guys!!
Hey guys, I'm still stuck with my problem here, appreciate your help. And I also need the radio ROM version 1.40.30.00 (that's the only radio ROM I couldn't try because when I clicked on the link shown in the forum I got a '550 Failed to change directory' error. Could someone plz re-opload the radio ROM somewhere and send me the link. Thanks.
Phone problems
Make sure you are SIM unlocked and not just Device unlocked. They are two different things. I've heard of some folks having to repeat the process a few times for it to "take". Good luck.
Hmmm... If an IMEI is reported as stolen etc would it cause the phone to work for a couple of minutes and than lose service? This may be something for you to check into. Just my 2 cents.
Alright got a question and I've tried everything I can think of here. I was running santod's tiKtaK and wanted to give his new 4.4.2 ROM a try. I installed it using the latest TWRP. TWRP restarted on me once but reading though the forum I should just try to install it again which I did. It installed and I got it to boot up. The only thing is now I have no Mobile Network signal or anything. Everything else works fine. I have no network, no signal strength, no phone number or IMEI listed in the phone. I have tried pulling the SIM Card and rebooting I have tried *#*#4636#*#* to change settings and all a no go. The thing is if I flash back to my other rom everything is there and working. Any suggestions?
I am having the same issue. Did you find any resolution? Or can anyone provide some insight?
We had a few hours network outage due to security reasons. But my G3 didnt recover when the outage was over and is still stuck at "no Service" even after several reboots, clean flash of cloudy and restoration to stock using nandroid. It was working just fine a night before. I have tried restoring Stock from nandroid but still no luck. I have tried different SIM cards too but still no connectivity.
*#06# shows proper IMEI number.
Any clue what might be wrong and how to go about fixing it ?

Update ::
OK So I looked around. my IMEI is correct. my wifi and bluetooth mac addresses are ok. but my baseband is shown as unknown. So i flashed a modem from here for v10D D850 and now I am not getting "No service" but still not getting any network
My suggestion is flash stock Rom with kdz or tot method. Look under general section and return completely stock.

OK so I am back to stock using TOT method. I have my IMEI, baseband and MAC addresses intact. Now it doesn't say No service rather it keeps on searching for signal and catches some from time to time but loses it again in a jiffy. Sim Toolkit is working fine so I assume SIM jacket isn't the trouble maker here.
search for signals :::: get a lock on :::: lose the signal :::: repeat
Any clues ?
Turn on airplane mode on and off. Factory reset your device from settings menu. It's a weird problem. It must be fixed after tot method.

Are you using it on At&t? Maybe sim gone bad or imei blacklisted by accident.
Which ATT APN are you currently using?
I'm actually having this exact problem to right now, I flashed back to stock and I still receive no data. I've tried nextgenphone APN and the PTA APN, I also checked my IMEI and it's fine to.
Edit:
I'm using an AT&T LG D850
When I put the sim card into my Moto G, it picks up 3G and works.

Ok so after having my go at the phone i had it given for repairs. The guy said he has replaced antenna multiplexer ic which has solved the problem.
I am experiencing the exact same issue but with a D855.
I decided to go from stock to CM12.1. This didn't end up working. Stuck on Bootloop. I also tried Xenon HD and had the same issue. So I came back to stock. Now having this issue.
What I did was flash from 5.0 to 4.4 so that I could root. I was unable to on 5.0.
Then I rooted using LG One click Root.
Then I flashed the latest TWRP
Then I did a full clean in TWRP and flashed CM & GAPPS (same with Xenon)
When this didn't work, I flashed to stock using LG FLash tool.
I tried both the KDZ and TOT methods numerous times, also tried to re-flash CM & Xenon and had the same issues.
I also tried flashing stock 4.4 and 5.0 roms and still the same.
I have also done multiple factory resets after flashing.
If anyone out there has solved this issue without sending their phone away, please advise as I am at my wits end and without a working phone.
Thanks

Got it repaired from Singapore Plaza Rawalpindi for 3k. Shop name was X-cell
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.

My previous LS990 worked charm with GSM networks. But recently purchased LS990 shows signal for like first minutes, then shows "Insert valid sim and reboot" message. hen reboots itself. after that sim is not recognised. The sim works fine on other phones. and tried many sims on this LS990, all failed.
Flashed KK, LP, MM stock with GSM unlock files, Fulmics rom, cloudy and AOSP. Fulmics seems to cath signals bit longer than other OSs, but it fails too.
Is this related to some hardware issue? but the thing is phone catches GSM signals flawlessly before above mentioned "Invalid sim" message. after that No sim is detectable.
Can anyone help me to fix it please? I would do a help to help. Donation :highfive:

You can try to flash modem only. Once i messed up some settings on the phone trying to unlock LTE bands and after that my signal was coming and going whole time, but no "Insert valid sim" message appeared. just on off. I have flashed ZVC modem from recovery and it worked fine. make backup of everything just in case and flash it.
