[Q] Rooted lg g3, No APNs, no ability to add APNs - Verizon LG G3

Hi, so before I go out and purchase a new SIM I was hoping someone could help me. Originally I was trying to alter the MMS port set in my APN because MMS was failing over wifi due to running Adblock. In doing so I somehow managed to erase my Internet APN. I believe it was just set to vzwinternet.
So on my lg g3 I unfortunately have no way to add an APN, it works fine for wifi and calls still but I have no cellular internet at the moment. The only option when going to APN settings is Reset to Defaults, which does nothing as it just shows "No APNs". The mobile networks option is actually greyed out under Settings->Wireless & Networks->More... but I'm able to get to APN Settings still by using an app.
Possible solutions I've thought of, does anyone knows if these are possible?
A) Is there any way to edit my build.prop to allow me to add an APN such as "ril.sales_code=LOL & ro.csc.sales_code=LOL" (I've tried this it doesn't work).
B) Is it possible to re-add it by replacing apns-conf.xml in /system/etc/ ? If that is possible could someone post theirs so I can replace it?
C) Are there any root apps to allow me to add an APN? (from my research there aren't any since android 4.0)
Or am I just going to have to go out and get a new SIM? I've already master reset hoping it was software related and that hasn't helped.
EDIT: Nevermind guys fixed it by doing a reflash back to factory with lg flashtool. Nothing to see here *whistles*

Hi Jab
I met the same issue.
Could you please tell me how to reflash back to factory?
Thank you

You need to root it, and use shortcut master to open APN setting, same case with my US Cellular G3

[Q] Flashing to Pageplus

I'm following the guide http://forum.xda-developers.com/showthread.php?t=1575749 for flashing the evo 3d to page plus from sprint. currently i have the phone rooted with s-off running meanrom. under the instructions it says you need to enter the MSID on the phone and if you don't have it to call your service provider. I called page plus and they say that they can't give me a MSID without the phone being activated on their service. I'm not sure what to do next. Do I give them the new ESN and have the change the service and then will they be able to give me the MSID or is there another method to do this?
Thanks for any help.
Edit: i'm currently on page plus with a old lg 9100 and the phone i'm trying to flash is a sprint phone that has never been activated.
second question: the apn backup and restore app says that APNS cannot be restored or deleted on this device because android 4.0+ does not allow 3rd party apps to write apn settings. what should I do to get this to work. i have the phone rooted with s-off currently running meanrom. should i put a different rom on there?

Have you flashed the page plus prl yet? If so you need to call them and give them your esn number. I believe the msid is for if you want to port your number over first before you call page plus. If you followed the guide to a T up until the apn part. Even though apps won't allow you to write to the apn, its ok because all your gonna do is delete and restore. Put your phone in airplane plane mode. Delete your current apn, click restore apn chose the page plus one. Disable airplane mode and reboot. I hope this helps you.

thanks, for the input. i'm going to try this a little later today.
so just an update for anyone who might stumble onto this thread. I figured out the steps: (Thanks Jsparta26)
After I flashed the prl, I called page plus and they activated the ESN. The MSID was the same as my phone number. Phone still didn't work, so i reflashed the PRL and then the phone was working. I didn't need to delete the APN, it was just working after. Now phone works for calls and 1x data. no MMS yet, got to figure that one out.
thanks for the help.
Your mms is also included in the apn file. Try the delete and restore method to see if works for you

I'm getting the message: Unfortunately APSs cannot be restored or deleted on this device because Android 4.0+ does not allow 3rd party apps to Write APN settings.
The Options in the Program are: Backup APNs, Restore APNs, Delete Backup Files, Delete APNs, and Donate.
Not sure what to do from here.
Ignore the part of backup, delete and restore. I was able to do this with an aosp rom and should work with a sense rom. You just cannot write to the apn file. Make a backup of your original apn, delete the current one, then restore using the page plus apn file and reboot. It should work. If not then manually copy it the apn file with a file explorer into your sdcard and take the page plus file and paste in the original location of the file and reboot. Let me know if that works.COLOR="Silver"]

[/COLOR]Which app are you using? Well if it don't work then I have another solution. Do you happen to know the settings of page plus's apn settings? Also do you know your msl code? If so, then open up your dialer and type ##3282# and punch in your msl code under edit. Once your through click on advanced and scroll down to the bottom of the screen and click on mmsc settings. If you know the settings you can manually input the settings in their correct spots. Once you do that hit commint changes or modifications at the top of the screen and hit reboot

I think I figured it out. In the settings for the program there is an option for "ignore ICS". i selected that and was able to delete and restore. looks like mms is now working, but it still shows 1x data.

yeah, 1x not so good.
Well I am glad that you got mms working. Not sure about the 1x signal, it could be a cell tower issue, not enough cell towers or that page plus's network is low priority. Have you flashed the latest page plus prl?

plenty of cell towers here, so that shouldn't be a problem. i'll try and flash the other prls and see what i get (right now i'm running the one from the main thread included in the rar). in the main thread i think there were problems with people not getting 3g. if i can't solve it with the prls, i'll have to comb through that thread for a solution.
Thanks for your help.

No problem. Just keep this in mind. Check to see if your radios are up to date on page plus's firmware. People used to have that problem when they went flash happy with the vm ruu ics leak back in may and messed up their phones with the dreaded 1x signal. Just something to think about. Good luck.

Help about creating new APN 4.1.2

Hello, and good day everyone!
I can't create a new APN in my phone. I own a samsung galaxay star GT-S5282.
I tried using giffgaff, but when i save the APN that giffgaff made, it isn't there. And I tried doing it manually too. It's not there when i press save.
I tried using APN backup and restore, and when i open the app, it says
"Unfortunately APNs cannot be restored or deleted on this device because android 4.0+ does not allow 3rd party apps to write APN settings."
I already checked the unknown sources in settings>security>unknown sources.
I don't know what to do to create new APN, so i'd appreciate it if someone can help me. Thanks and have a nice day! :good:
EDIT: Btw, I already searched for it. But unfortunately can't find any solutions.

Install system app mover.apk as well as busybox.apk These are also available on Playstore.
Also install APN manager pro.
Run system appmover and turn APN manager pro into a system app.
Run APN manager and adjust/insert APN as you please. You can even delete the default entries and put your own. You are now ready to connect to a network of your own.
Make sure you have the correct modem and have network signal on your phone.
Get in touch in case of any query.
Cheers,

FIX for unable to add APNs (tested for LG G3)

For some reason I was unable to find this anywhere on the internet but managed to fix it myself, so I'm writing here to document it.
I have a T-Mobile LG G3 (model LG-D851) and after rooting, something happened that made me no longer able to add APNs. On top of that, there were no APNs registered on the phone, so I was unable to access any form of mobile data, although telephone worked. T-Mobile's technical support wasn't able to find the solution either. (In retrospect, using Titanium Backup to restore telephony data (messages etc.) likely corrupted my APN database).
Basically what was happening was in Settings -> Networks -> Tethering & Networks -> Mobile Networks -> Access Point Names, it said "No APNs", and selecting menu -> New APN did nothing; no menu appeared or anything. Basically I didn't have T-Mobile's LTE APN registered and I couldn't re-add it.
I tried a lot of things to fix it, but the solution was actually very easy (requires root): in the root directory, go to /data/data/com.android.providers.telephony/databases/ and notice the "telephony.db" file. This is an SQLite database that has the APN data in it, but in my case it was corrupted. I simply renamed the file, then rebooted my phone (actually, the phone crashed ) and voila! LTE was working good as new on restart. The system detected the file was missing and created a new one with default settings; that is, with T-Mobile's APN already inside. "Add APN" also works now.
Maybe someday this will help someone else in my situation. Basically, be careful with Titanium Backup, haha.

No service (no data, no cell, no nothing) on xt1526, possible APN problem?

Fellow XDA
Stock xt1526 here with Android 5.1 no root or any other customization. After switching from R+ to Ting I lost service for good.
I am assuming it is APN related but I couldnt get the change the APN settings since it is greyed out in setting menu. I am wondering if there is a way to change the APN with my current set up?
If not; is rooting a solution to change APN? Can you please share some link how to change APN with root?
Can installing other ROMs help me to get the service back? and/or allow me to change APN?
Thank you for your helps

TCL A30 android 11, stock ROM rooted visible wireless

Hi, I have a TCL A30 and I am attempting to use visible wireless. The problem is, I can't change my apn settings. I tried to edit the .xml file that contains the apn and but no luck. The file doesn't save. I have tried so many different things and it is the only thing that is preventing me from really being able to use the service. When I use adb to launch the apn setting, the options for mvno are greyed out. It's as if the sim card contains something that forces the os to not let you change any apn settings. I've been working at this for a couple of days and the only thing I am able to use is vzwinternet. I want to be able to use hotspot and high speed data and the only roadblock is these apn settings. There has to be some way to manually configure apn settings that I am overlooking. If anyone has any insight please let me know. It would be greatly appreciated. TCL A30 running android 11 rooted.
