Data/3g network fix for XT720_XDA_Special_STB2

First, make sure you have background data on in settings/accounts & sync
You can try Apn Manager to set your apn settings
if those don't
Find a fix here, it worked for me not sure if it's the best way
http://forum.xda-developers.com/showpost.php?p=16200053&postcount=365

My apn settings seems to work with only the data files of the first special stock (i don t do all the apn stuff)
But i have a lot of others issues
The first time i try it with out the data from the first special stock i had my google account and i had the phone process problem again....
I restore the data from nandroid and then the french language disapear......
ANd the biggest problem is that i can t connect my google account it always tell me that i don t have a network connection but all the other apps go to the net with out a problem...
And i have this problem only with the data from the first stock....
I maybe do something wrong... I install the nandroid image on the singapore sbf and my card is already part like it must be (fat 32 ext3 and swap).
I m right???? Maybe someone could make a new topic explaining all the step because it become more and more difficult to follow all the problems....
I don t try the boot.img or the others a2sd gui things...

Are you on wifi? Can you send pics via text or email? If you get that text document and find your apn settings from that list and add it to the text document then replace it /etc/apns-conf.xml you will get your data and 3g network back. I thought I had my network to cause I was able to text and make calls and stuff, but didn't. it only worked for calls and texts, not data. Also make sure you have background data turned on in settings

Thanks for the help but i give up with wanhu...
I always have problem with this one... First with the phone process FC and now the market... I spend more time trying to install this wanhu roms than with all the others (miui....) but it always have issues and big ones.....
I try the cyanogen one and it work a lot better (for me)
I m on it since only one hour now but i think it will be my winner.....

hmm i'm doing sth wrong..i did all those steps, but was a bit confused when editing the apns-configs file, i deleted too much text: that's what it's exactly looking like

I would expect that to work.

Replacing apns-conf.xml file WORKED!!

here for everyone who isn't able to fix 3g - just download this file :
http://www.share-online.biz/dl/8DB1TBPLWR
this is the old apns-conf.xml file from xda special alfa_h ROM.. you need to delete old apns-conf.xml file in /etc/ directory (you get there by using root explorer & co) and copy this download-file there.. just reboot -> 3g / internet data should work now. if it doesn't , you can try wiping cache / data , for me it only worked after factory reset then..
and here are also those two data-files from x_special_alfa_h ROM, I don't know in what way they might be needed for 3g fix here, but just try copying them into sdcard/nandroid/OpenRecovery/XT720_XDA_Special_STB2 and then get into OR->nandroid->restore ALL

[Q] How do you get the Hidden menu dial codes to work??

I have a Verizon Galaxy Note 3 that i purchased from my brother. Theres no issues with IMEI or insurance or cancelled past due accounts. I pop in my Tmobile unlimited LTE sim card and i get LTE speeds without rooting or switching to band 4. Every now and then it will revert back to HSPA Plus speed but rarely. %99 of the time its on LTE. Only thing i did was put the correct APN for Tmobile LTE. So its great that the Verizon Note 3 works right out the box for Tmobile LTE. I want to enable AWS and Band 4 anyway. So i Root the phone using the new Toweroot method which was as easy as clicking a link and thats it. The phone is rooted. Heres my problem: I try and enter the code in the dialpad the *#2766336837# and nothing happens. I re-enter the code and press send this time and i get the error message "Connection Problem or Invalid MMI Code" Why is this happening? Is there a prior step i am missing?? I read about efs/carrier switch to enable this from off to on but how do i access it?? Please note that the tmobile sim card is in the phone when i attempt to do this. Should there be a verizon sim in to do this??
All the help would be appreciated.

Samsung disabled most of the dialer codes for the Note 3, including the service menu.

1- I'm not sure what is this code used for, but it seems the correct code is 27663368378, not 2766336837 (?)
2- Do you have a screenshot if this code was entered successfully? If yes, I can make a shortcut directly to this feature without entering the code.
3- Anyway, you can enable the hidden menu by follow this guide:
3.1- Make sure the file hiddenmenu.apk is present in the /system/app/ folder.
3.2- Install Terminal Emulator from the Play Store.
3.3- Enter the following commands:
Code:
su
echo -n ON > /efs/carrier/HiddenMenu
3.4- Reboot your device.
3.5- Try to enter these codes: *#06#, *#0011#, *#27663368378# (my suggested code) OR *#2766336837# (your original code) and see if it works.

Thanks. This method worked I am now able to access the service menu and change to band 4 but I noticed that band 4 was already active so much for that.

At least with a VZW SIM in, the adding of those 2 lines removes any access to Access Point Names in Settings.

I did have a space. The effect is definate... I tried it several times... After reboot with the lines in... The setting settings->connections->more networks->mobile networks->Access Point Names dissappear. A couple of other options appear but neither leads to APN. I remove those 2 lines and the APN option reappears.
The value is letter L letter O letter L not letter L number 0 letter L correct?
I too am using Jasmine 6.01 and idlekernel (not leankernel)

Nope... I'm bootloader unlocked too... If fact I am the guy who modified the unlock code to work on 4.4.2 and earlier VZW Note 3 devices.
No biggie... I am on Verizon and intend to stay on Verizon so there's no need for different APN for me... Just curious to see what changed.

Using Galaxy tools I was able to change the mps code from upper case to lower which allowed editing of apn settings. There is a file some place in root you could also edit.

Does this now for sprint S7 edge build apd3 un greys APN option to be able to edit. So hotspot is working??? If so any step by step or videos preferably?
Sent from my SM-G935P using XDA-Developers mobile app

So, I tried ##BRAND#.
It more than debloats your phone. It clears out ALL sprint settings including those that give you data access. However, you do gain access to APNs as long as you have MSL. I had to input all my APNs back in to get 3G to work. Still trying to figure out why 4G and LTE isn't working.
I suspect I can do a hands free activation and get my data access back by doing a master reset. ##72786# doesn't even get me a reboot, and I can't update my profile at all. The PD3 update got downloaded but there was an error along the way so the data is still there but it can't be installed even if I wanted to. I'm hoping the master reset clears this out, and then I can disable the update service with my new access.
PS... for what it's worth, I have PC5 and am not able to keep the "You are not subscribed" popup from turning it off. I suspect I can disable DSS to prevent that but my focus right now is to get LTE and 4G capability back.
I'll update as I explore more.
Edit: Seeing "Installing system update" is not what I wanted to see......
Edit2: doing a system reset fixed LTE and 4G connectivity issues... and brought back the bloatware. Fortunately, no update to PD3. I'll try again to see if I can get the data settings to stick after debloat.
Edit3: For future use just in case. For LTE replace EHRPD with LTE at location.
Name: APN2 EHRPD internet
APN: n.ispsn
MMSC: http://mms.sprintpcs.com

MCC: 310
MNC: 120
APN Type: default, mms, dun
Protocol: IPv4/IPv6
Roaming: IPv4/IPv6
Bearer: eHRPD
Edit4: sooooo no dice. I've tried taking sim out before reboot, after reboot, master resetting it, debranding it, manually entering APNs....... nothing works. APNs greyed out. The most likely way to get this to work is to stop the activation mid way and try to modify it then.
I've also started noticing a new message appearing. Something to the effect of "Applications are locked or disabled from modification" or similar. That never happened before today.
Still going to keep fiddling with it, but I'm running out of ideas.

[GUIDE] How to edit APN on unlocked Boost Mobile LG Stylo 2 LS775 (and others?)

1 - Extract MAINROOT.zip to your adb folder.
2 - Open a Command Prompt as administrator in your adb folder.
3 - Type in step1.bat in command prompt and hit enter.
4 - You should now be in an adb shell prompt, type in run-as con and hit enter.
5 - You now have shell access and you can tweak the android system with these permissions but tweaking the barebones of the linux kernel will be impossible without a full root. Selinux is the culprit.
6 - You can use the package manager (pm) to block apps and settings command (settings) in this adb shell prompt to tweak the workings of android or use the activity manager to access the hidden sprint and lg menus to change APNs and tweak CDMA radio control.
7 - In the adb shell prompt type in pm list packages and hit enter.
8 - From the list of packages find one that has system activities we'd be looking to access and tweak such as com.lge.hiddenmenu.
9 - Type in dumpsys package com.lge.hiddenmenu and hit enter and in the list you will see activities which can be started, such as com.lge.hiddenmenu/.Power.TherDaeMitigation.
10 - Type in am start -n com.lge.hiddenmenu/.Power.TherDaeMitigation to start the activity.
11 - You'll want to disable thermal mitigation to boost the raw performance of the phone.
12 - Repeat steps 7 -10 to access any activity you find interesting and wish to tweak.
13 - Hint : am start -n com.lge.SprintHiddenMenu/.iot.IotHiddenMenuMain is a good one many people were hoping to access.
Thanks to @anthonykb. He was on ZV6 firmware version.
I no longer have a stylo 2 so I am limited in what help I can provide - I just asked @anthonykb for permission to post this guide here because I knew how much I wanted to do this when I did have it
This method may also work on other phones such as LG X Power (someone care to try?)
It also might open a path to find a way for permanent root for those on firmware higher than ZV3?...

Can i add GSM apns with this? I have a LG Stylo 2 LS775 ZV6

and like what the OP says I no longer have a stylo 2 so I am limited in the help I can provide, you might have to load a different package or something

ask @anthonykb he will know more than me

Hi.
I'd appreciate your input on my situation - unlocked Boost LG ls775a on Android 7, Z8, - I have SPC code, I have access to h*n menu.
T-Mobile SIM - only LTE mode works. I can send SMS or browse internet, but regular call does not work. If I press call #, - the phone permanently attempts to call, no error, - you can switch to other apps. T-Mobile Fast APN.
I tried to turn on VoLTE RF in h*n menu, but no luck.
I believe the phone might be still configured to route calls thru CDMA (Boost legacy). Can you give me general approach on how to de-couple from CDMA or any other ideas to make regular calls work?
Also, if I switch from LTE mode, say, to GSM/WCDMA auto, - nothing works at all (no calls, no internet, SMS - not attempted).
Next, I tried FreedomPop SIM (for ATT). FreedomPop registers thru WiFi. Then I turn off WiFi. In LTE mode - no internet, no calls (in FreedomPop calls routed thru Internet) are possible.
I read somewhere on XDA forums, that ATT doesnt allow LTE if MIED is not registered with them, so not registered phones work on slower-than-LTE protocol/speeds. Other phone works with FreedomPop, H+ is displayed next to connection quality bars, and ATT is displayed as network. Does it mean I need WCDMA working on the phone, and it somehow doesnt work?
I have menu similar to this t=2022763

Edit APN
Hello. I'm from Ukraine. I need your help. I have a phone LG G Stylo LS770 android 6.0. In it, the network of the Ukrainian mobile operator is working, you can call. But the Internet does not work. The APN settings can not be changed. How can this be remedied? Thank you for the information.
