[Q] network problem after rooting installing roms

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.

go to dev tools after you set up your apn and hit 'crash system server' if that doesn't work. use titanium and restore apn's.

Try apn backup from the market first. If data works on our Rom then backup those apn configurations with that app then restore it on your new Rom.

im going to flash renovate and try the crash system trick. thats the only one i havent tried, as ive never heard of it. but, as far as backing up apn's, several apps including the new ics compatible tweakker app, say the device isnt supported to restore apns. fml. i really want to try these newer roms. i hope the trick works.

hey do you have an apk of dev tools? i just looked through my backups and i dont have that app

well i found the current dev tools apk and crashed system server on a fresh install of aokp. setup the default apn's and also the set i input manually to my roms. neither worked. apn backup and restore does not work. says this version of android doesnt allow the use of 3rd party apps to manipulate apns. what else guys? im stumped and really want my roms to stay current and im slowly and surely getting left behind

still no luck with 4.0.4
just a bump here. nobody still have any clue why my carrier isnt working with android 4.0.4? ive tried everything listed here. I know how to setup apns properly. theres just something different about the 4.0.4 roms, sense or aosp based, that doesnt let me connect to data.

so... find the ruu for vietnam. download it. go fastboot oem lock and run ruu. this will flash your phone completely stock as if it came from the factory. good luck! if you get confused or lost, use google search...

i will definitely give that a try kemmo. if the latest ruu work itll have me scratching my head as to why custom 4.0.4 roms wont work lol.

Look at this legitness, you know I dont follow the One X cause its all about the GS3.....What version of android does it work on, the 4G? Has anybody else had success with 4g on the 4.0.4 Roms that your not having? Where are these ROMS based out off, international versions or US?

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?

LG G3 D858HK flashing Fulmics ROM 5.3

Thanks @xpirt makes a nice rom for G3.

D858HK has not many custom and I really want to try Fulmics even it does not support D858HK.
So I look around and finally in Chinese forum, found a method to flash Fulmics.
On Fulmics ROM 5.3, my D858HK works smoothly and the battery performance is similar to stock rom.
Everything is ok and I can use 4G. (I use one sim, two sim is not test.)
The only problem is the IMEI is lost (but I can still give and receive call) and the advance wifi in setting will force close.
I don't know whether it is work for your phone. I am not responsible for any harm to your phone , I am just sharing what I did to flash the rom.
What you need(in my case):
stock 6.0 rooted rom
TWRP(I use the unofficial twrp_3.0.2-0_d856_16-05-14)
http://forum.xda-developers.com/lg-g3/development/recovery-twrp-3-0-0-0-t3309475
Attention:You may lose you IMEI.
Follow these steps:
Make a whole backup of stock rooted rom in TWRP and you must backup the boot, modem, EFS and IMEI. (because if you lose the IMEI, you cannot go back to stock via KZD,TOT and LGUP.)
Put the Fulmics ROM 5.3 , dual sim v4 and modem5_6_3 into external sd card.https://drive.google.com/open?id=0B-NY-GIlMMxSV0tMSmtEYndIMmc
Ｗipe everything in TWRP. (Be careful：Don't wipe your backup)
Flash Fulmics, you just choose d855 in aroma installation.
When finish the installation, don't reboot, you should go back to TWRP and restore the boot and modem and then reboot.
After reboot and setting,you will find your phone cannot detect the sim card and wifi do not work.
You need to flash the dual sim v4. (please note that it is in Chinese)
If you lose your baseband and no signal, you can try to flash the modem5_6_3.
I found the dual sim v4 and modem5_6_3 in Chinese forum and they are made by @piaoxue99
I don't know these file is trustworthy or not but thanks @piaoxue99.

Hi, this sounds nice! Are you able to activate LTE on both SIM slots?

Excellent process has successfully ..... thank you

Hi GaryfromHK,
I have successfully installed it but i have noticed the following: Do you have any solution for these?
FM Radio is not functioning (even i installed the modem you provided)
I lost signal whenever I select the both status (my phone number, model no. IMEI, etc.) of sim card but it goes back normal here’s the error message “Unfortunately, the process com.android.phone has stopped”
I cannot activate guest user there is pop up error always
thanks and hope to hear from you.

We should be calling developers attention helping us out with this very limited ROMs for our beloved dual SIM LG G3
