The other day I took the plunge and decided to root my phone and install some ROMs. It was all going well until I started noticing that I wasn't able to make/receive calls or texts. I had gio pro 1.4 installed when I first noticed this problem and I had read that installing cyanogenmod 7.2 had helped someone with a similar issue so I installed it.
Now I have cnmod 7.2 installed with the same problem and with my carrier name changed from virgin to bell. If I restart my phone I am able to call and send messages for a few minutes but then craps out again.
Hopefully someone can help me
Thanks in advance!
no network problem
unfortunately u are having the same issue as me you have to select use 2g only which is only good if you are on a network that supports 2g the nv data file become corrupt somehow and you lose 3g capability i am trying to figure away to fix the gio but to no avail right now

Actually I found out why I was having this problem recently. Turns out I have a different model of the gio (gt-5660M) . When I installed gio pro 1.4 I completely overwrote my stock firmware including the baseband so it screwed up my network settings. I had to find my stock firmware, flash it using Odin and then I just installed clockwork recovery and flashed cyanogenmod 7.2 using that. It's been fine working since then.
Thanks anyway!
well atleast your lucky i restored my original software and it has the right modem when i do a network search it picks up the 3g networks just wont connect to them
Yes, I accidentally did the same to my GT-S5660M. What I did was reflashed the stock ROM and then rooted, installed CWM recovery, and flashed a custom ROM, being careful not to override the baseband. Thankfully the ROM I flashed used CWM recovery and not Odin, and I didn't have to worry about a thing.
Just got Samsung Nexus Korean maguro variant yakju with 4.1 installed and with Baseband: UGKL1 and my network is Warid Tel - Pakistan. I used my local sim in as well and it was working fine. Today I tried to use custom 4.3.1 in it and so I done these steps:
Downloaded Nexus Root Toolkit, Android SDK, Latest Nexus drivers and all pre-requisites before starting. Now I first started to unlock my Bootloader with matching requirements as the tool already do this. Then flashed cwm touch recovery and applied root. I tool backup of my stock rom via cwm and then wipe all and installed liquidsmooth 2.7 which is jb 4.3.1 and it worked like a charm. What i noticed afterwards that the rom is reading my carrier details correctly but also showing Emergency call only warning as well. I tried Edge as well and it was wokring normally but when i tried to dial a call and tried to send txt it showed me Mobile network not avaialable. Then I tried all latest radio basebands on it, tried all settings SMSC and normal troubleshoots but couldn't get complete carrier support. Then I restored my default stock rom via cmw and boom no issues like it should be. Now my question is did I missed something for it? or am I flashing wrong basebands? or somthing else? After too many hours i felt that I cannot go further from here. I am attaching my screenshots. Please if anyone can tell me or guide me I will be very thankful to him as I haven't tried my phone yet, just got it. I had HTC evo 3d and its setup of everything never got me stucked like this.
Anybody up for help kindly

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?
Okay so i have the T-Mobile Galaxy s3. It has been rooted for a while with zero problems. I got tired of the older android on it and decided to install a rom. I installed Cyanogenmod 13.0-20151208-unofficial-d2tmo running android 6.0.1. When i first got it all booted and loaded with gapps, i noticed that it recognized my sim and that i had a signal but i couldn't use any LTE or just all around data. basically i couldn't go online (in case i just didn't explain that well enough. Phone service is a mystery to me). I did some searching online and found a lot of people saying that i needed to update my baseband. i found a baseband for my model (T999) and tried to flash it in TWRM. Once i rebooted, it said "No SIM card - No service." in the upper left-hand side. i have tried flashing multiple different basebands the same way with no luck. i tried backing up my EFS folder and the restoring it because someone said to do that and that just... just no... it didn't do anything. even Odin 3 said it was a "FAIL!". So here i am with this android equivalent to an Ipod and i hate this. Everything else in this ROM works perfectly aside from this but this is a super big problem. PLEASE HELP!!!! A phone isn't a phone if you cant even send a text.
Did you update the phone's bootloader and modem to the latest version before flashing CM?
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.
