Hi All,
I appeal to you keepers of the knowledge to enlight me on some points I need to clarify.
The situation:
I recently bought an unbranded Oneplus 6T and I (still) use stock oxygen OS V9.0.17.
Since a couple of years I've been using a data-only plan with a VOIP SIP account as my main phone service. It was working great on my beloved almost-6-years-old Nexus 5 until I dropped it to it's death. I chose the 6T as replacement because it seemed a good option for rooting and custom ROMs.
My service provider is FIDO in Canada. They offer a very good value data-only plan (15$ CAD for 4GB), but for an UNKNOWN reason to me, with FIDO the SIP calls drop automatically if I use the default autoconfigured APN for LTE. The simple solution to that is to create a new empty APN config and fill it manually. Once done, SIP calls work like a charm (again, I don't know what causes this).
On my Nexus, I was running Android 8.0 which permitted me to modify the APN. But since Android 8.1 Google (don't be evil right) introduced the APN locking for participating providers. FIDO seems to be one of them since I cannot change any APN configuration on Oxygen OS 9.0.17. That renders my phone useless (unless I choose the 3G apn, which honestly sucks).
Now that you know a little bit about my life, here are my questions.
First thing I did:
I rooted my phone with Magisk 20.0 with the intention of modifying the /system/etc/apns-conf.xml and try changing the default FIDO APN configuration with the hope it would work.
I tried by many ways to modify it (using ADB, root browser, root explorer, solid explorer) and I couldn't change the content. Even worse, when I tried to change the permissions to the file to RW using root explorer, the file turned empty (0b) and it's still impossible to modify it (I tried editing it, deleting, replacing it, nothing works).
Question 1: The simplest of ways would be to be able to change the APN. Does anybody knows a trick (using root or not) to do that on stock OOS 9.0.17. Anybody ever tried changing apns-conf.xml?
Question 2: Did anybody succefylly edit system files onstock OOS 9.0.17 using root?
Question 2-A: Does anybody know why I break the file when I change the permission? I'd like to understand what's going on.
Another option that I am considering is using a custom ROM that disables this nonsense APN lock mechanism.
Question 3: Does anybody have a good ROM suggestion that is positively disabling this APN lock and that would allow me to change my APN with FIDO? (I was considering Lineage but I couldn't get a firm answer on the APN unlock capability).
I searched the web for many hours without success, I hope you can help me with this.
Thank you all for your insight.

Have you tried creating a new apn with the info and settings you need?

Yes! I tried that many times.
So, what happens is when you have an "APN locked SIM" inserted in the device, you have no access to any edit option. No editing, no adding, nothing. You are in view mode for the APN settings (which is useless really).
In my research I found that if you insert a "not APN locked SIM" you get acces to creating a new APN (and of course editing the actual SIM APN settings).
I happen to have a SIM card (my girlfriend's) that is not APN locked on hand. I tried a couple of times creating a new APN with the FIDO settings but when I inserted back the FIDO SIM my new APN was not in the list of options.
... I should have deepened my research! I failed at that...
What I didn't realize at the time is that when you create a new APN, Android defaults the MCC and MNC parameters with the values associated with the currently inserted SIM!!! I tought it was some kind of black magic settings used by the service provider for it's network to work. But not later than TODAY (I did more research today...) I learned that: MCC = Mobile Country Code and MNC = Mobile Network Code. ****!!!
Sooooo, all I had to do is create a new APN with my girlfriend's SIM inserted and set (along with all the other settings) the MCC and MNC to the values corresponding to FIDO config (which in the past I left as is since I didn't know what they were). Save. Shut down my device. Insert FIDO SIM, reboot, and fuc**ng VOILA!!! The newly created APN is now available and... wait for it... EDITABLE!!! So if I messed-up any setting I can change it and play around with everything like we did when Google was not Evil.
So here I am with my un-activated FIDO SIM and I can confirm that my newly created APN is selectable, but I cannot try a SIP call for now since I've closed my account. Tomorrow I'll get a new subscription & SIM and update this post. But I think this part is solved.
All that being said, Question 1 is partially answered to my greatest pleasure. But I'd still like to hear your experiences about modifying sytem files on OOS with root access.

Any Indian user (preferably DOCOMO user)..could u please send me the apns-conf.xml file from ur phone (PM me for my email id)..It would b of great help as i can't use GPRS/3G on my phone on any stock or Custom ROM. Now, i've already tried the following stuff-
1)Used the global apns-conf.xml (Didn't work)
2)As i'm able to access these services on stock XXJP2...took out the apns-conf from it and exchanged it with my current rom's apns.(Didn't work)
3)i'm currently on JPM...and the only features tht i'm missing in it are 3G/GPRS.

Just manually enter the following in apn settings
Name: anything /Docomo
Apn: TATA.DOCOMO.INTERNET
Apn type: internet
Rest leave it as is
After that turn on the apn but don't press back key,instead to go back from settings use home key.
Restart phone n you should have internet ;-)

Your welcome
it always does
Being a Europe firmware, the APN list might not be there for Asia. I had the same problem and had to manually configure the apn. It worked.
Not a big deal as long as you know the access point details for your subscriber.
Any way to make it automatic in a firmware/rom of outside like europian ?
Hey guys, I was wondering if anyone else has seen this:
I've added a new T-Mobile APN to specifically add 'dun' for Tethering. Everything else is the same as the stock 'locked' APN provided by T-Mobile.
My issue is, even though my 'new' APN has default as the first type, it always reverts back to the stock APN either at random, or when I reboot the phone.
Has anyone else seen this? Is there any way, with these newer phones to completely delete the 'stock' APN?
Thanks!
Yes I have experienced this as well. Any solution?

Unlock default APN on the V20
Try this:
1. Open your stock LG Dialer.
2. Enter this 277634#*#.
3. Click on "ApnUnlock".
4. Select "Unlock APN".
5. Now go edit your stock APN.
Change the APN Type to this...
default,admin,fota,mms,supl,dun
Let me know if it helps.

build the apn into the stock apn list. it will reset back to the modified one aka stop doing this.
i dont know it tmo does service updates but with sprint updating the prl updates the apns.

Thanks so much. I copied then deleted my stock TMobile apn. I am on mintsim wireless and it has its own son settings but my v20 kept going back to the TMobile apn... Thanks
No problem... Glad it worked for your particular need.
if you have a problematic firmware that won't allow you to edit your APN settings in the dialer hidden menu, this may be what you need.
first, the warnings:
1. THIS IS ONLY FOR SPRINT SAMSUNG PHONES RUNNING TOUCHWIZ ROMS!!! never attempt on any other carrier or manufacturer's device or alternate roms! it should most likely work on other Samsung Sprint devices with stock/touchwiz roms.
2. DEPENDING ON DEVICE, YOU ARE MOST LIKELY TO BE FORCED TO FACTORY RESET YOUR DEVICE IN THE PROCESS, which likely includes LOSS OF ALL DATA ON INTERNAL SD!! take all necessary precautions.
3. ROOT REQUIRED
4. you will STILL NEED your MSL number!!!
5. have a FULL backup in TWRP ready in case anything goes wrong. INCLUDE your EFS in the backup!!! again, INCLUDE YOUR EFS. make sure it's stored on EXTERNAL sd card. again, EXTERNAL SD CARD!!! or copy it to your PC if you don't have an external card.
here's the short but sweet guide.
1. download "Samsung Phone Info" from Google Play
2. swipe over to the CSC section.
here you should see:
Firmware's CSC Code
Active CSC Code
Available CSC Code
3. if Firmware's AND Active both say XAS, you should already be able to edit your APNs using your MSL number.
if Firmware and Active codes do not match, you have a dirty rom and I am unable to help you correct it, you'd best try a different stock based rom or 3rd party that allows it by default.
if Available CSC Codes does NOT include "XAS" then whoever modified the customized stock touchwiz rom you're using removed it and you'd best try a different stock based rom or 3rd party that allows it by default.
4. using any CSC editor, change "SPR" in ALL places it appears as only the 3 letters "SPR" to XAS
5. confirm changes and reboot. you will now most likely lose ALL personal data on your phone and should now be able to edit your APN using your MSL inside the dialer's hidden menu.

Have you found a way to retrieve your MSL without calling sprint? I've tried all the tool apps in the play store and using a logcat within the ##3282# menu with no luck. Getprop ril.MSL yields nothing, not even a not found error.
I've tried calling sprint for my MSL but refuse to release it.. I'm not exactly on their "nice" list - they've even called to tell me I'm "using too much of my [UNLIMITED] data" many times so I don't expect much from them anymore..
Any help or direction would be greatly appreciated
try the Sprint chat -- through the website, NOT Facebook, and have a good reason ready as to why you need the MSL, other than for bypassing their security lol
Holy **** after searching high and low I have FINALLy found a way to get back editing my APNS for hotspot on my rooted Sprint Note 5! AND I keep Android Pay! Thanks so much!!
This works perfectly! Only thing is turn on hotspot option disappeared from settings. I can turn it on and off from the top bar if I swipe down. OR I can download a hotspot shortcut app and access it from that app.
Also I noticed my icons for LTE now say 4G and the bars are different too - more old school.
I noticed I changed EVERY SPR to XAS - do ALL of them NEED to be changed to enable APN editing? Can I switch back the ones that give me back hotspot option in settings and stock LTE & bars icons?

this **might** be fixed by renaming (or deleting, if you're brave) the features.xml file, if I remember correctly, stored in system/csc/ or system/etc/ not sure honestly
features.xml.backup should do just fine.
if the rom doesn't boot afterwards or if the dragons catch all your apps on fire, go back to recovery and use TWRP's file manager to change it back
also, any xposed app (like wanam's) or other feature.xml adjusting apps (like GalaxyTools or Samsung Phone Info) can cause the problem to happen again.
the alternative / temporary / dirty-fix would be to create a shortcut to hotspot on your home screen:
1. download Activity Launcher from Google Play
2. launch and change recent activities to all activities
3. wait approximately 72 years for it to load
4. scroll to Settings and tap it
5. scroll to Hotspot and long-press it
6. tap create shortcut
7. never uninstall Activity Launcher -- instead just make it a hidden app (it's very small anyways)
I can just longpress hotspot toggle in slide down drawer from top no probz. Which CSC settings modifies the ability to edit APN? I want to put the rest back to SPR.

I used the msl code and everything appears the way you say it should... but the phone STILL says invalid sim!
What internal file must be deleted, the thing is unlocked on sprints end it just wont let go !

Hello,
I rooted Sprint Note 5 from Nougat to Magisk and went ahead to replace SPR into XAS in all files under system/CSC folder. APN Type is still coming greyed out. Any help will be appreciated.

Ok so I use @jrkruse guide https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616 to root my SM-G935P on Oreo and it works great but I cannot get LTE working, Now when I rooted my phone on Android N with @godpowerrr tutorial https://forum.xda-developers.com/sprint-s7-edge/how-to/sm-g935p-spr-root-nougat-7-0-data-t3568780 and do the build.prop tweaks I get LTE working fine. I have tried to add the same build.prop lines to my rooted oreo phone with no success would anyone happen to know where to find the settings in the build.prop from android N in android oreo?

Try this. Go into your phone dialer and enter this secret code:
##3282# (puts you in programming mode)
Click edit.
For the MSL code, put "000000" and press OK.
On the main screen, go to MORE.
Then click HDR/1x Selection.
On this screen, select Global then press OK.
The phone will restart and should enable LTE.
Hope this helps.

If Global doesn't work, go thru the process again and try the next 2 settings.
Unfortunately I have tried that and it does not work for me.
@DirtyPISTOLA This is a step you might of missed and has been throughout my thread. (Apn settings need to be applied after eng boot is registered) I implemented these settings through a .bat file in device system/etc folder, but doesn't work for all. So if you apply the eng boot through ODIN...and upon reset... Edit APN settings through mobile networks, being;
Name: APN2 LTE Internet
APN: n.ispsn
MMSC:http://mms.sprintpcs.com
Multimedia message proxy:68.28.31.7
Multimedia message port:80
MCC: 310
MNC: 120
APN type:default,supl,mms,dun,fota
APN Protocol:IPv4/IPv6
APN roaming protocol:IPv4/IPv6
Bearer:LTE
You should be able to run SuperSU .bat file and hopefully that'll fix it. If not it's a firmware issue.
I'm not sure if this works for oreo because I no longer have this device, but these are settings needed for LTE. Like I said idk if Nougat's LTE is different from Oreo's LTE.
Build.prop entries:
ro.characterisitics=Sprint
ro.telephony.default_network=10
ro.cdma.default_numeric=310120
ro.cdma.default_alpha=Sprint
ro.cdma.home.operator.alpha=Sprint
If this doesn't work try SM-G935U firmware with exact settings and steps, but change MNC: to 000.

Awesome thanks for the reply, I just upgraded to a new update that wont let me downgrade because of security policy updates as soon as SamMobile posts the firmware so I can restore if something goes wrong I'll give this a try. Thanks again.
Glad I finally found this thread, which firmware should I be on if I want to root this thing? Thinking of flashing Boot Loader 6 though again not sure.
Hey hey, I need to dig up this ghost here, cause I rooted a Sprint S7 Edge and put a verizon SIM in it, I don't have an active sprint SIM so I can't test it out, but the verizon SIM isn't getting any LTE, it just shows roaming, and no MMS messages can be downloaded. I may or may not have messed with some settings.
So, I can't edit the APN settings it's locked out. How can I either a. unlock the APN settings, or b. get it to recognize LTE networks without doing that. I've tried so many different things I've found on the forums, like nova launcher menu and going into the IOTHidden stuff to get into LTEfunctionality and that's not even there on the phone.
We're running OREO, but I just don't know what the deal is. Any ideas?

Even with the inactive sprint SIM I am given options for APN settings, I can't edit or add any, but I do have options, whereas with the Verizon card it's all frozen out
I have a K20 plus. I used the Device Unlock app and was granted permanent unlock the first time. I then unlocked the bootloader and rooted. I then installed PBRP and installed Lineage 15.1. Some times I have 4g most times no data. No cell service. I've installed new firmware to make my mp260 to a tp260. I now have apn settings loaded. However I can not modify them. What am I missing. How to restore service?
Are you on a Metro SIM or an original Tmobile SIM?
For me, being on Metro and on LOS 15.1, the APN settings that worked best was setting up a new APN using T-Mobile info, not MetroPCS. Even if the phone is an MP260, I believe since the LOS image is utilizing a TP260 fingerprint the Tmos APN worked much more stable than MetroPCS. I've had no issues with shoddy 4G since doing that.
You can't edit the default APN, so if you need to change any parameters you need to create a new one and copy over the details either from the default APN or one of the websites or there that provide some info for APN parameters. And be sure to select it afterward, not the default uneditable one.
One thing I did was change the IPv4 setting to both IPv4/IPv6 since i think the IPv4 only setting which comes default was giving me intermittent connection issues as Tmobile has switched over to IPv6, as far as I understand having read waaaaay too much into the matter trying to fix all APN/SIM/cell problems I encountered with custom ROMs.
