"No service" - G3 Q&A, Help & Troubleshooting

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.

Flash suitable Kitkat modem for phone.

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.

Did you resolved the issue?
2 different theories.
1 try to remove the usim card, and put it back.
2 flash correct kdz for your phone by lg flash tool 2014 using CSE flash.
I've sold the phone, no luck fixing it, had no use for an android media player. I saw previous similar issues, and people said they resolved it by flashing the mexican kdz onto it, and then the korean one again, but I couldn't find the kdz anywhere, and just decided to call it a day and get a phone upgrade.

Mobile data not working +STOCK ROM

Hi everyone,
I have LG G3 d855 (Europe version). I bought it online, not at any network. I had an lollipop update really fast (Poland). Yesterday I rooted the phone, it worked fine, and installed the BlissPop rom. I missed the Quick Circle option though, so today I installed the ChupaChups rom for lollipop. And now my problem: The mobile data connection is not working. I can make calls, send texts, connect via wifi, but the data connection over the network is not working at all. I went back to stock - I downloaded and installed the European version using kdz method, it didn't help, so I did it over LG Flash Tool. It still does not work. Do you have any ideas, what to do with this? I feel like I'm going to cry, I'm very nervous about it, because I use mobile data almost all the time...
Maybe there's something wrong with the modem driver? I really hope someone is able to help me. Thank you in advance!
Edit: Maybe I used the wrong stock rom? I don't even have the option to update to lollipop anymore.

Seems like a modem baseband was flashed somehow.
Flash the modem back to the correct stock version you had and it should fix the problem

Do you know where I can find those modem drivers?
Edit: I checked which version of software I should use with my IMEI no. It's 20h. Would it be enough to flash the stock rom over kdz, or do I have to find somewhere the modem driver for this version? If yes, do you have any idea where can I find it?
Thanks.

Not sure.
I have the G2 and we have these files in our Development Section where you find ROM files etc.
Should be there as flashable zip files in the same section for the G3

Ok, thanks! Last question before I do the final step - I have the ROM I am supposed to have. I rooted the phone, installed TWRP. I've also found the modem driver for my rom. And the question is - how should I flash the driver? Should I mount system or do anything apart from just installing the zip? Should I clear any cache?
@CaPlanePourMoi Wipe the modem partition in Recovery and then just flash the modem zip which will replace it. If that doesn't work, you can go back to BlissPop that includes it's own Modem and install Xposed for 5.1 Super-Alpha and the QuickCircle Mod for AOSP, all 3 of those I'm using with no issues whatsoever!
So I installed the modem driver (20h) yesterday, but it didn't help. I decided to install the BlissPop ROM, and mobile data (with LTE) works just fine. I will go back to the problem on Saturday and keep you up to date. Thanks!
Update
Update: Hey everyone - it seems like I didn't find any solution. I tried to go back to the ROM based on stock again (it was Cloudy this time), but the modem still didn't work. It was acutally working for a few seconds (I had 4G connection), but then again it was lost and it didn't connect anymore. Wifi works fine. Do you have any ideas on how I can flash the modem correctly? And how can I uninstall the modem that I have now in recovery? I didn't do that, because I cannot find this option.
Thanks in advance!

I have a very similar issue
my LG G3 is the D855 on AT&T , and was working fine on Cloudy 2.2 or 2.3 Lolipop without any issues!
All of a sudden last Friday 5/22/2015, mobile data stopped working, but WiFi is still okay.
I just did a full wipe, updated APN, and the issue still there
I haven't change any major things in probably 2 months, not sure what's going on.
Finally, contacted AT&T, and made sure that they remove from the network,a put my back(troubleshooting). As well as changing the sim, and APN, but nothing worked!!
PLEASE HELP!!!!!!!!!!!!
UPDATE: So my last attempt, I contacted my provider AT&T, and they requested to try a default APN settings, even though what I used was working fine.
I did, and immediately my mobile data was back!!
Everything is working back as normal, and for some reason the network APN required updating
Did almost the same few days ago! I have finally solved my problem. Here's the explanation:
In Poland we had a network called "Era", a few years ago it was bought by T-Mobile. I searched the internet for T-Mobile APN settings in Poland and it didn't work. I have also found the APN settings for the old network, "Era" and surprisingly it's working. I don't know why T-Mobile settings don't work while they do for other people (and at this point I'm too afraid to ask. )
HI, i have the same problem on my d855 with wind (i'm in italy), i was rooted with custom rom and when i came back to stock i lose data connection. What i have to do? what do u mean for restore default apn? the default of my carrier? or the default for g3?

D850 cant connect to GSM. stuck at "No Service"

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

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.
