TCL A30 android 11, stock ROM rooted visible wireless - Android Q&A, Help & Troubleshooting

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.

[Q] Unable to save proxy settings

I am currently running the O2 ICS ROM on my GSII (rooted): Courtesy of Faryaab's fine thread.
Base: I9100XXLPR
Build: XWLP3
Kernel: XWLP3
I need to use a proxy to access https:// sites. I can input the info by 'long-pressing' the wifi name > Modify Network > Show advanced options > . At this point I input the Proxy address and port then click save, but it doesn't! When I go back in the Proxy settings are reset back to 'None'.
Anyone have a solution to this - is it a bug? I will be updating to the new UK ROM when I get home which might help, otherwise I am scuppered!
You need to download an app.
I have ASProxy (paid) and it works fine for me to get outside my work's proxy server. I had tried a couple prior that didn't work for my situation.
There are others (both paid and free). Most of them require root, which you already have.
I may give something like that a go - but for the time being, I'm actually trying to use the proxy server that the service provider offers, the problem is I can't get my phone to save and use the settings. Every time I try it just seems to default back to no proxy.
Does ICS not support the use of proxy servers via the wireless settings? There is an option for it?
Edit: Having looked at ASProxy that seems to allow you to get around the fact that most Apps do not use the proxy settings you specify when you set up your wifi connection. Although I will need something like that, at the moment I can't even get the browser (default or Dolphin) to use the proxy I want as it won't 'stick' in the wifi settings.
Unable Wifi Proxy Address and Port
I am also facing the same issue on Coolpad Note 3 running Custom Lollipop 5.1.
When I enter the proxy details and click save and go back to check the advanced settings, they are gone.
Please guide me where I can fix this.
Thanks

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,

[Q] Rooted lg g3, No APNs, no ability to add APNs

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

Help Mediatek Android (Made to look like IOS)

Hi could anyone help me I have an Mediatek Iphone 6+ Clone which is actually Android. although thats a problem in of itself. The problem I'm having is that I am unable to enter the APN settings, I am able to navigate to the APN page but there is no option to add APN (I'm guessing where Android has a "Menu" button to bring up Add APN, the IPhake doesn't). I've tried various method such as APN apps, Floating menu button apps and now i'm trying by ADB.
First off I have rooted the phone.
the APN settings I need are
APN Carrier: Lebara UK
I have tried the following a few guides which i found via googling but I cant seem to get them to work
I would post what I tried however I am unable to post URL's
You won't find much help here. We don't deal with knock off devices.

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
Flash stock modem files via Fastboot..
Change APN app usually works for me
