[Q] changing MMC erases APN entries - AT&T Samsung Galaxy Note I717

I have been trying to add the AT&T APN to my unlocked Rogers i717r note, and have, after a process of elimination, discovered that adding an APN is functional, UNLESS I change the MMC or MNC port numbers. If I add an APN, it sticks just fine. But if I go back in and change the MMC or MNC ports, then it disappears off the list for some reason.
Does anyone else see this phenomenon?
For general info, I am on the stock ROM, rooted kernel, and touch-based CWM.

This thread has some relevant information. Mainly its because the Radio Interface Layer does not allow switching to another MMC MNC protocol.

The fix found in that thread is this:

Dunno if it will work for the Note, but it seems like it is a general android hack, and not hardware-specific. We shall see.

[Q] Cannot set up AccessPoint after flash GingerMod-6.1

After upgrading my phone to GingerMod-6.1 (http://forum.xda-developers.com/showthread.php?t=1400023) my phone could not create an AccessPoint (Setting->Wifi & Network->Mobile network->AccessPoint) because:
- MCC, MNC are required fields, so for awhile searching I found value MCC, MNC of my network provider (452 and 01), but MNC must be at least 3 digits
After that I install AccessPoint over Setting message from my Network Provider, finally installed AccessPoint, but now my phone still could not connect to the Internet (although 3G signal is very strong).
One more: whenever I create new AccessPoint with valid values of MCC, MNC, after press Save, the phone's access point list still empty with out any warning message????
With the old ROM, I even dont need to enter value of MCC and MNC
Anybody tell me why ??? I dont want to upgrading to another firmware because my personal data

Changing the " unchangeable " MNC field in APN settings?

Heya ,
My MMS is not working after flashing a custom rom ( HTC ONE X on VirginMobile Australia ).
I realize its to do with the APN settings , I have updated them manually but the MNC field needs to show : 02 , currently its set to 029 - if I change it , it deletes the whole new APN I have put in and Im left with no connection at all.
Is there anyway to change this MNC field? I read on another forum that there is a way through ES File Explorer... going into system/etc and the APN file - but I tried that , and there is def. no APN file in system
Thanks
I'm having the exact same issue - were you able to resolve?
Heya,I'm not sure which country your in.. but I found a solution here ( Oz ) you just have to leave the MNC to whatever it has defaulted to, no point changing it because it won't save... And manually set up APN for internet and APN for mms for your carrier ( settings usually found on the carriers website ) . Just don't try to change MNC ,leave whatever your phone has input. It should still work.
Hope that helps ?

[Q] Editing APNs, Verizon > Metro PCS *** SOLVED ***

*** SOLVED, see third post ***
Hello, I'm trying to use my VWZ Note 2 on MetroPCS.
I'm rooted, stock 4.4.2.
When I use the buildprop edit suggested here, my "add access point names" menu disappears entirely:
http://forums.androidcentral.com/ve...41691-mod-add-apn-editor-system-settings.html
If I remove the buildprop code, I get the menu back, but I can't edit anything.
I pushed my own version of "apns-conf.xml" to /sdcard/ and then pasted it into /system/etc/ and replaced the old one, changed permissions to read-only. Also tried read/write all permissions open.
I can now click the "+" button in the APNs screen. I can add/save APNS, but when (and only when) I have ALL of the correct APN info put in, it instantly deletes the APN I've added. Up to that point I can save the APN, see it in the APN list, and edit it further.
I restart phone, the APNs are all gone except the grayed-out "LTE - Verizon Internet".
I got an app to read the APN settings from the SIM card itself (the one I'm already using on my metroPCS phone). Interestingly, these are the networks on the SIM card:
T-Mobile US
Simple
StraightTalk T-Mobile
solavei
T-Mobile LTE
Added both of the T-Mobile APNs, which did save to my access point names, but no network still.
Then I realized that I am a monumental idiot. I put the SIM back in my old metroPCS phone and got the APN settings from there. For future use, here they are:
Name: MetroPCS
APN: fast.metropcs.com
MMSC: http://metropcs.mmsmvno.com/mms/wapenc
MCC: 310
MNC: 260
APN type: default,supl,mms,hipri
APN protocol: IPv6
APN roaming protocol: IPv4
Let's try putting those in my note 2. Why the heck I didn't try this sooner is beyond me.
Still nothing, "No signal." Also, "SIM from unknown source."
EDIT: As I suspected, the APN settings weren't being saved to apns-conf.xml in system/etc/
So I pulled, edited, pushed my new version of apns-conf.xml to have the correct metro pcs settings, put it back in system/etc/, set the correct permissions (read-only for the system).
Now I have the MetroPCS access point name, it matches apns-conf.xml, but still no connection.
I think I'm about out of options.
SOLVED.
If mod wants to truncate this into one post total, that's cool.
My process to get MetroPCS working on a VZW (Verizon) Note 2.
1: Root it
Get ghettoroot 2.2: http://forum.xda-developers.com/attachment.php?attachmentid=2924899&d=1409874318
Download android SDK
Set environmental variable for adb commands. Note that you add the command after whatever is already in "path" variable, with a semicolon between: http://jaxov.com/2010/10/set-up-adb-on-windows-7-vista-xp-for-android-phones/
Uninstall any samsung stuff, especially KIES. Then install samsung drivers: http://www.samsung.com/us/support/owners/product/SCH-I605TSAVZW
Ghettoroot your phone. You'll need to enable usb debugging, under developer options. How to enable developer options: System settings > about phone > Build number. Press "Build number" like 7 times or so and it will unlock dev options.
Now we need to do some APN settings. Follow this for the method, rest of this post for the info: http://forum.xda-developers.com/showthread.php?t=2044449
APN info (if value not shown, leave blank/default):
Name: MetroPCS
APN: fast.metropcs.com
MMSC: http://metropcs.mmsvno.com/mms/wapenc
MCC: 310
MNC: 260
APN type: default,supl,mms,hipri,*
APN protocol: IPv6
You'll want to have those settings both in the apns-conf.xml, and in the More Settings>Mobile Networks>Access point names
Activate your phone with MetroPCS.
Remove "Unknown SIM card" notification: Long press the notification to figure out which app is creating it (app info), then use titanium backup to uninstall it.
I have read and read i am having issues now since the sim message is generated by tbe system ui i cant kill this is in the verizon note 2 when i install the sim it force closes everything any thoughts would be great.
Ugh. Try doing a factory reset and starting over.
Make sure you use TitaniumBackup to uninstall (preferably freeze if you own pro) the app that's causing the SIM message. You must be rooted of course. Not sure why things would force close, you might have got rid of wrong system app.

How to get data and mms/sms to work on other variant note 3 lollipop roms

All this is, is a simple guide to get data and mms/sms working on "most" other note 3 variant 5.0 lollipop Roms. As an example, we will use darklord 2.2. This method has worked on most of the Roms that I have flashed that are not sprint based.
OK. You are going to need a few apps. APN manager and APN changer and root explorer. APN manager is a paid app, but worth it when flashing other variant's roms. When you do flash DarkLord 2.2, you will need to do so with philz recovery. It will not flash in TWRP. Once the phone boots, choose your language and when you get to the second screen asking about sharing your data usage. Check "no thanks". It should be the second option. Log in to Google play store and download those three apps. Open APN changer first. See if there is an APN already there named sprint. Even if there is or is not. You will either change a few things in it or if there is not one, you will create one. Either or, you APN should read as follows. . . . . .
NAME: APN LTE internet
APN: n.ispsn
PROXY: not set
PORT: not set
USERNAME: not set
PASSWORD: not set
SERVER: not set
MMSC: http://mms.sprintpcs.com
MULTIMEDIA MESSAGE PROXY: 68.28.31.7
MULTIMEDIA MESSAGE PORT: 80
MCC: 310
MNC: 120
AUTHENTICATION TYPE: none
APN TYPE: default,mms,dun
APN PROTOCOL: Ipv4/Ipv6
APN ROAMING PROTOCOL: Ipv4/Ipv6
TURN APN ON/OFF: should be checked but greyed out. Can not change this.
BEARER: LTE
MOBILE VIRTUAL NETWORK OPERATOR TYPE: none
MOBILE VIRTUAL NETWORK OPERATOR VALUE: not set (can't change this one either, greyed out)

In this link, download all the files.
APN file
Lib file
Mms apk
Push the APN file to system/etc folder. Just replace the original file and set permissions.
Push the lib file to system/lib folder. Just replace the original file and set permissions.
Now take the mms apk and push it to system/private folder and place it in the mms folder. Just rename the original one with. bak at the end of the name. Set permissions. If you are not sure to what the permissions should be, pay attention to see what the permissions are for the file you are replacing. But I am pretty sure that all the permission settings should be as followed
RW-R--R--
Reboot. Now go back to the apn changer app and see if your apn is still there. Might be unchecked. Just tick it. Give it a few minutes and see if data starts up. If not, go to the apn manager app and scroll to the next screen to right. There will be a very long list of apn configurations of multiple carrier's. Scroll through and see if the APN2 LTE internet APN file you created is there. Should be in alphabetical order. Once you find it the vertical bar to the left of it should be green. If not, press or long press on it and you will see a heart at the top of the screen. Press it and it will save it as your preferred apn configuration. If LTE does not appear, just reboot, go back to apn changer and tick The apn that is now there and LTE will now be working. I have tried this method and shared this method with other members and it works. I am running darklord 2.2 now. Have been for a few days. Sorry There are no zips for this. If someone wants to make one, then by all means go for it.
Here is the frameworkres.apk that I modified for darklord 2.2 Push it and set permissions. It will display sprint instead of roaming indicator off. You might want to push it to the system folder first then set the permissions, then take it and push it and replace the original in the framework folder. Might put you in a boot loop if not done that way first. Thanks to @legalmoneygang for the winzip tip.

Must give thanks to @sac23 for being a silent teacher. I read everything that he has posted throughout all forums. He is the one that I learned about the lib file for mms. Plus I love every rom he puts out. I truly admire what he can do.
And thanks to the guys over in the international forum for the awesome darklord rom and the relentless work ethic they put forth. @nambavuong and @thereassaad and @filchi756.

These are my steps that I use, and I have flashed dang near every touchwiz rom for every note 3 variant. Once you get into the habit of this and have the needed files. This process only takes a few minutes.
Hope i have not left anything out of this lengthy so to say how to. Hope this helps. If it does, then awesome. Glad we could get it working. If it does not help. Sorry you couldn't get it to work.
Ill try your method on Sacs Ported V2 for now because when I flash DarkLord Rom I get the "no sim"
even after following OP. I cant even test your method because once it says "no sim" cant even
turn data on, says no sim, lol.
Ill report back with my results...thanks for the method though!!!

What ROM are you using? Some variant of stock?
I'm having calling issues in the various CM versions I've tried.
edit - the GSM version of the GPE ROM works fine though. Flashed it with Danvdh's VZ kernel.
Originally on stock of1 but just flashed stang5litre but the method worked on both.
So I have to root to get MMS on to get the VZW S4 to work on T-Mobile correct?
So if I follow this guide: http://forum.xda-developers.com/galaxy-s4-verizon/general/samsung-s4-i545-verizon-of1-root-t3254434
I should be able to jump right in to your guide?

Yes sir!
I get a screen which says "Device Locked". the message goes on to explain this is likely because the phone has been locked down by manufacturer (carrier?) and even rooted devices can have problems due to SELinux restrictions.

If you see that message it's because the su binary is not high enough. Install the apk in the same folder that is linked in the OP, open supersu and update if needed then try again after rebooting.
Thanks. I got it to work. Looks like the SMSC number needs to be re-entered after each reboot and texting doesn't work in LTE mode, but looks easy enough to toggle back and forth when necessary.

Glad it's working for you. I haven't experienced the rebooting problem though. Do you have any other network apps that may be auto setting the smsc number at boot?

Check under your mobile network settings, make sure network mode isn't set to global. It should say gsm/umts. You may want to re apply settings after changing modes. I noticed the global setting screwed up my tmobile settings so hopefully it's related to your issues.(fingers crossed)

I followed your guide for my dad's verizon s4 but I am running into some problems.
I rooted it following the root guide linked earlier in this thread and root is successful. SuperSu is installed and root checker verified.
However, in my APN settings, under APN Type, i have to manually type in "Internet+MMS", and the under APN Protocol, the only choices are ipv4, ipv6, ipv4/ipv6.
Also, when I open the advanced signal status app, do i select the LTE/GSM (PRL), is that what you meant?
edit: even just selecting GSM auto (prl), i still cant get 3g, 4g, or LTE. Only edge.

Having to manually enter your apn type is normal. I have "internet, mms, supl" typed into mine. The problem you are having with the app being locked is because your version of the su binary isn't correct. Install the supersu app that is included in the OP. Before doing anything else you will need to open the newly installed supersu app and allow the binary to update. After it has updated immediately reboot and it should no longer be locked. Also back under the APN settings, don't mess with the ipv4/ipv6 settings. Just leave them at default.
When I get to APN protocol, it's not giving me the option "WAP 2.0".... Only IPv4, IPv6, and then IPv4/IPv6.
Also not giving me the option to save the newly created APN. What to do next?

Sorry about the APN, I copied it but didn't proof read.

At the bottom of the tutorial is a link to a google drive folder with two apk files. Download them and open them on your phone to start the install. After installing "supersu.apk" click open and accept the upgrade, click normal when asked what method to use then reboot when it prompts. The lock will be gone.

Great, thanks alot man that actually worked perfectly. Another question though... so in order to do what we just did, You have to have absolute root access to your phone right? i opened a terminal emulator app and notice that i still have the dollar sign on the command line. But when i run "su", it has the hash symbol which i'm assuming means i'm root now or at least have root privileges. Shouldn't i have had the hash symbol as soon as i started the emulator? does this mean my su binary is still not high enough?
