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.

Im having the same issue i purchased a used G3 and it says " NO service" ive tried eveything and verified with sprint there is no block on the phone. got a new sim card from TING ... the phone will activate only over WIFI but i have never been able to get cell service Is this a hardware issue? im totally lost and TING is telling me to take it to a cell phone repair shop. ( 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?
Hi there developers. First of all sorry for my so bad bad ENGLISH.
So I have purchased a used LG G3 F400k Korean Variant with 3GB of RAM and 32GB ROM. When I first used the phone it runs stock lollipop and all seems working fine, not to mention it's Battery life and heating issue. Until then I got boring with its stock Rom, I rooted it and installed a Bumped TWRP via Flashify. The Flashify says I am installing a recovery that can replace my boot, but I still flashed it. It was succesful as it directly boot me into TWRP. Now when I tried to reboot it gives me an error boot like that and an infinite black screen with disco light led notification. I have no memory card yet and so I get my laptop and searched for its solution here on XDA. I flashed it using unofficial lg flash tool with 2 files such as ott and I forgot the other one. It was succesful an I reverted back to stock kitkat. And now the problem I faced is I CAN NO LONGER RECEIVE CALLS but I can make an outgoing call and it takes too long to ring when I am dialing and my network here has a menu when accessing *100# but it always failed and it gave me an invalid mme code or connection problem. I then flashed a twrp back and before I did that I have already downloaded the Fulmics Rom and flashed it through TWRP, thinking of the problem is by the rom itself. It was succesfull again. But then again my problem didn't solve by flashing another Rom.. And now I don't know what to do my imei is still here but still I have this problem. Would be appreciated if anyone would just reply to my thread and provide me some idea
Sorry I can't provide you screenshots coz I can't upload due to restrictions to a new members.
My Internet is so good. It's fast. Its LTE. I also turned off the VOLTE calling and Call forwarding or call rejecting. But still, my family is having problem contacting me because their call is directing to my Voice Mailbox. I tried putting my sim card in other phone and it's fine. I tried putting different SIM card to my phone and still facing the same issue. I think it's a hardware problem? Please help me.! I haven't tried bringing this to shop coz it's very expensive and thinking of someone could help me here instead. Please HELP!
Hi everyone
i have an lg g3 d855 EU working just fine for 1 year and a half ,
And lately when i upgrade to Marshmallow and then i stated flashing a different custom roms and they all work fine!
But a week ago I got a strange problem! A sudden msg appear for few second and then phone keep rebooting:
“Mobile network will be unavailable until you restart with a valid sim card”
I’ve done a lot of research and tried them all but still the same probe:
-put a piece of paper on the top of the sim cad
-replace the sim card
- Factory reset
-flashed android 5 the original kdz file got from official lg firmware using my IMEI
-....
So I decided to get it to a technician!
-so he replaced the sim card reader with a new one! After that the phone went just fine for 4 days and then the problem come back, so I get it back to him, so he replaced the reader with second new one and he told me that the reader is not the problem and is 100% working so when I put the sim card and reboot it ask me for "pin code" but when I after put the pin code, the phone keep searching for signal for few second than it stay no service at all.
the technician sad that there is some file in lg g3 responsible for the service detection and stuff like that only be obtained from another working lg g3 and only solution is that he can get those fil from a working lg g3 and put it into my phone and he told me it will be working again for sure !
So please guys help me I’m stuck !! Is there anyone know something about these files or their names?? And if he can provide me them I’ll be so grateful. :good:
Haven't seen this problem before. A file issue? Perhaps do another complete factory reset then do a complete wipe flash of the global rom, using the LG flash tool. Get the rom here http://forum.xda-developers.com/lg-g3/general/lg-g3-android-marshmallow-discussions-t3216143
I use that rom so there shouldn't be any issues. Hope this helps

Hi all,
I bought an LG G4 from Aliexpress Two months Ago, I think it's an LG G4 H815T (hong kong version) It was working perfectly until I decided to upgrade the firmware (to android 6) with LG bridge and since I made this action, I could not get signal on the phone (most of the time) and some times I get full bar signal but only emergency calls are allowed.
I tried also to downgrade to android 5 again but with no succes (I tried all possible roms and for all variants)
the strange thing is that the phone was working quite good so I'm sure that it's not a hardware problem.
Can any one please tell How can I fix that?
thanks in advance
Does any one faced the same issue before ?
Same here
I don't know if you are talking about the same issue but this occurred for me randomly. Before restart used to fix it but now nothing helps, also when I search for carrier it says your sim card can't connect to any or something like this although I have full signal bar :|
Same issue with mine
Try to restart the phone when it's connected to a power-supply or a running computer, it works for me
Same issue with
My problem is the same please help me?
thanks...
My LG G4 H818P also have the same problem.
Hope there is a solution for this.

You have to install flash stock 4.1.2 F180L KDZ again (yes! the korean one). Regarding IMEI/ No service, no one can help u if the EFS partition is lost (because that contains the phone info to be registered on the network).
The bootloop u had at CM13 has even easier fix than all of this KDZ mess. When I had my E975, The problem I had was no signal in CM12.1/CM12 so I had to resort to CM11. The F180's are so much falling into this crossflashing mess that its difficult to diagnose what can be the culprit.
Get the JB firmware flashed and check if u have imei.
