Is volte absolutely impossible in gsi rom? - Treble-Enabled Device Questions and Answers

Hello, U12+ Korean user with the lowest number of users in the world. First of all, it's nice to meet
I modified Qualcomm efs files related to volte, modified buildprops, and entered forced commands. Ims is activated. I'm wondering what else I need.
(I'm sorry that the screenshot is not in English) ims registered, and it says that video calling is possible, but volte is impossible.

Previously, it was possible to replace the Qualcomm efs file in original ROM and create the carrier code xml in system-customize-MNS through the volte activation menu in the basic phone app.
For reference, htc was withdrawn from the Korean market 10 years ago. I purchased the Taiwan version and copied the Qualcomm ims files of the Korean telecommunication company from Sony Xperia xz2 firmware, the same Snapdragon 845 model released in Korea, and opened the forced port through the adb shell command. After replacing the file in efs explorer, I made a Korean carrier (45008etc.xml) in the mns folder by looking at the Taiwanese carrier code and getting a hint, and also modified mns.map.xml in the customize folder, so volte in the original phone app-config The activation menu appears, so even though it is not released to Korean users, we applied tta .volte, which is only available in Korea.

Create a while list of phone numbers?

Is it possible to restrict the phone numbers the phone can call?
I want to restrict calling to certain list of approved phone numbers. Is this possible?
Should be possible with any phone and carrier, as long as you know your sim's PIN2 code. You should be able to enable it in Settings > Call > Fixed Dialing Numbers.
Good luck finding your SIM PIN 2 though. The default for T-Mobile is supposedly 5678, but I have found that it is hit or miss whether T-Mobile SIMs actually have the default values.
I can't speak for US users, but in Romania every SIM comes with its own set of PIN, PIN2, PUK, PUK2.
So I'm SOL with a Bell Desire Z?
If you can't find the PIN2 on the SIM card (the large, credit card-sized one), call Bell and they should be able to provide you with one.
Maybe I'm just missing it, but on the European ROM I can't see anything under Call->Settings for fixed dialling numbers.

Build 1.34.405.5, CID HTC__032 (WWE, not branded)
Thanks. That's odd though, because I'm on that same ROM version and I don't see those options. I can only guess that it must be carrier/SIMcard-specific ?

Problem Setting up Google Wallet?

If you can't get Google Wallet to work as a new install dafoxs has come across some interesting information. There is a change in the SIM card AT&T will be using and he thinks the inability to set up GW as new has to do with this new SIM. I contacted AT&T corporate c/s and this was the response they gave me;
"Thank you for using AT&T!
This email is a follow-up to our conversation earlier today; below is a summary of our discussion:
• Based on our discussion on 4/19/2013 regarding wireless number(s) 215-XXX-XXXX the following items were discussed: the isis mobile wallet system does require a new sim. the new sim is called Gemalto UICC-F SIM card and it has an embedded secure element. however it has not yet been launched in your market and therefore the sim cards are currently not avalible to you.
If you have further questions about your AT&T account, please refer to http://www.att.com/biz or by calling us at 1-866-ATT-7629."
dafoxs believes (and it makes sense) GW has made some subtle change on their end to make their app compatible with AT&T phones and are also using this new secure element. If this is the case we may be SOL until the new SIM becomes available.
That's funny, just got this. The item number is there

[Edit: Superfluous.]
When I ordered my SE SIM...ATT verified my location before issuing the card for use with ISIS.
So it makes sense that if users don't reside in the ISIS test areas, ATT won't issue cards if they can't be used.
Why would they. ..
This is a serious problem. ..in getting a working gwallet....g

This is common knowledge with most Android devices. Most here also disable it as it is really useless.

That is because Google is blocked on China devices. You have to find a rom for your device that is not china based.
no more idea

Not all devices are flash able and to be honest most of the China based devices are the worst. They seldom even use an official version of Android. More a hacked together version.

Lacking of mobile networking after unsuccessful a firmware rollback

Hey everyone. I've faced with a problem I can't cope by myself. Once upon a time I found out despite the renewal was turned off on my phone that my phone was updated to MIUI 11. I didn't like it so much. It had buggs, terrible design and devoured phones charge like a fish. I lost my nerve and made rollback. so, I lost everything that makes a phone different from a brick with lights. After that I decided to read about ) but It was too late. So, I lost all of system settings due to antirollback policies. What about backup? certainly I hadn't made it. I had one on google drive but It didn't give it to download.
I found some efs files and managed to recover system settings such as wifi, imei, modem, almost everything except the mobile network and the internet. the engineering menu shows the efs is unknown.
It means the efs I recovered my phone isn't suitable for my phone version or I need radio.img in addition to, doesn't it?
I'm going to try input SN number via a special utility into the phone. I don't expect anything from this step, but...
I suppose I need some with radio band settings or something from it. Or I need to find the new EFS files, don't I? I remember the file I'm restoring the phone was the ancient fossil of 2016.
how much does it cost to buy up-to-date EFS? Where could I find them? Where should I look for?

Question call recording

Hello,
is it possible to enable call recording on the global version?
I don't want 3-party applications like Cube or ACR.
I want a stock dialer with call recording.
Thanks!
Yes, it is. Recording is implemented into the call app, so whenever you are in a call you could start it. Quality seems to be really good. The file is saved under phone recordings.
Dim9000, Origin OS, Global Version, German language: Aufnahme = Recording

I have Global - European fiwmare, this fw dont support it
MY FW: PD2185BF_EX_A_12.0.12.5.W30.V000L1
I've only ever seen China phones support native call recording. Might be illegal elsewhere. My China x80 pro dimensity supports it
I used to have a huawei phone where the situation was the same. The Chinese version allowed the system application to record the call, the European version did not due to legislation. This could be solved by installing the recorder application, extracted from the Chinese rom. Shouldn't the same be done here? I also own an X80 Pro and am looking for a solution.
i think it is impossible. We try to install on x80 pro and x70 pro plus global versions the apk form a chinese x70 pro plus version and doenst install it. Anyone have any solution? It is locked in the firmware to not support all global versions?
is there anyway to make auto call recording without notification on global version?
