K20 plus. Unlocked no network - LG K20 Plus Questions & Answers

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.

....also CAN SOMEONE WHO IS RUNNING A NEW CM6 BUILD POST THEIR TMOBILE APN ***ONLY IF THEY HAVE FULLY FUNCTION INTERNET AND MMS**** THANK U )
Go to APN setting for T-Mobile.
Just delete the name, password and server so it should say "not set "then save. Your internet should be working. That's how I did it.

Help required verizon samsung s5 - activate hidden codes

Hello
I am using verizon sansung s5 900v on a network other than verizon. I wanted to know whether i can activate the hidden codes without rooting my set. Further is it possible to use other network 4g on this set. I have heard that i can only use other network 4g if i can enable hidden codes. I dont want to root my device. Any help would be highly appreciated
I may be wrong, but im pretty sure enabling them requires root. So to answer yout question, no you cannot without rooting.

I don't think you need hidden codes just to use another network. You just need to input the correct APN for mobile data. Now, if the codes provide functionality to recharge on that network, etc, then you won't be able to. You can simply root and change the appropriate setting and unroot and it will stick, since the setting is in the EFS filesystem of the phone.
You only need to do step 2 from the OP here after rooting on the S5: http://forum.xda-developers.com/showthread.php?t=2303905
FWIW, I was recently in Puerto Rico and was able to buy and use a SIM card with 4G data just fine on my Verizon Galaxy S5 after inputting the correct APN information and selecting GSM/UMTS as the network or Global instead of LTE/CDMA. Verizon's handsets are usually unlocked by default.
If you have the latest software update, band 4 should already be enabled, barring there is some sort of SIM check to determine if there is a VZW sim card installed, but I doubt it.

APN Settings revert after every reboot?

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?

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.

LTE On Oreo After Root?

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?

No its locked for sprint network.
LTE on 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

Oxygen OS, root, APN and the meaning of life

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.
