Guys with ATT devices, an easy request is to make an EFS backup and put it here or in a private message.
The essence of the problem: after experiments with aggregation, which did not lead to anything, the phone no longer connects to the mobile network, exept GSM (2G)
Backup to do this:

0. Turn off phone, remove the SIM card from the phone, this may be important. Turn on phone.

1. Enable Port Check Test on the device : * # 546368 # * 600 # -> SVC Menu -> Port Check Test -> tap Port Check Test (Enabled)

2. Install, if not already, LGMobileDriver_WHQL_Ver_4.8.0.exe

3. Download the file EfsTools-0.14.zip from here https://johnbel.github.io/ , unpack the archive using a short path

4. Download and install .NET 5.0 Desktop Runtime (v5.0.5) - Windows x64 , required for the EfsTools.exe program to work from point 3

5. Connect the phone to the computer. Go to the EfsTools-0.14 folder, open a command window (Left mouse on an empty space in the folder with SHIFT pressed )

6. Check if EfsTools.exe sees our device by entering EfsTools.exe targetInfo or EfsTools.exe efsInfo If the output is like this:

D: \ EfsTools-0.14> EfsTools.exe targetInfo
Imei: 354783110718874, SerialNo: '', MobileSoftwareId: '', DiagVersion: 8, CompilationDate: 'Apr 28 2020', CompilationTime: '21: 49: 11 ', ReleaseDate:' Apr 22 2020 ', ReleaseTime:' 6: 00: 00L ', VersionDirectory:' MV600AM: ', MobileFirmwareRevision: 0, MobileCaiRevision: 255, MobileModel: 0, StationClassMask: 9, SlotCycleIndex: 48, HwVersion: 0.229, MSM: 0xE52, MobileModelId: 334, MobileModelName: 0, Guid: 'deadd00d-d00d-dead-0dd0-adde75191006', SystemTime: '15 .04.2021 6:56:41 '
GSM VocorerDspVersion: 0xDEAD, MdspVersionRom: 0xDEAD, MdspVersionRam: 0xDEAD
Call state: 0x0

Or like this:

D: \ EfsTools-0.14> EfsTools.exe efsInfo
Version: 1, MaxDirectories: 50, MapPathnameLength: 1024, MaxFileSize: 0, MaxFile
nameLength: 768, MaxMounts: 36, MaxSymlinkDepth: 0

then you can go to step 7.
If an error occurs:

D: \ EfsTools-0.14> EfsTools.exe targetInfo
Fatal error. Object reference not set to an instance of an object.

then you need to change <efstool port = "auto" in file EfsTools.dll.config to the number that the LGE Mobile USB Diagnostic Port device has from the device manager. For example: <efstool port = "COM17"

7. Make an EFS backup by entering EfsTools.exe downloadDirectory -i / -o. \ Backup _ $ {date: format = yyyyMMdd_HHmmss}

D:\EfsTools-0.14>EfsTools.exe downloadDirectory -i / -o .\backup_${date:format=yyyyMMdd_HHmmss}

D:\EfsTools-0.14>

8. The folder backup_20210418_114359 (backup_date_time) will appear in the EfsTools-0.14 folder , archive it, put it in a secluded place and share the archive. Plus, I ask you to add a software version to the name of the archive, such as V600AM10p

9. Disable Port Check Test on the device : * # 546368 # * 600 # -> SVC Menu -> Port Check Test -> tap Port Check Test (Disabled)

attached a sample of what should turn out.

Thank you guys.

D:\EfsTools-0.14>

8. The folder backup_20210418_114359 (backup_date_time) will appear in the EfsTools-0.14 folder , archive it, put it in a secluded place and share the archive. Plus, I ask you to add a software version to the name of the archive, such as V600AM10p

9. Disable Port Check Test on the device : * # 546368 # * 600 # -> SVC Menu -> Port Check Test -> tap Port Check Test (Disabled)

attached a sample of what should turn out.

Thank you guys.
damn I have the t-mobile variant only as I switch carriers often as AT-T will not allow wifi calling if phone is not AT&T branded or if the branded phone isnt on their sim card/network.

Thank you for responding. Could you please make an EFS backup from your T-Mobile.
I still have nothing to lose, but suddenly, with a good outcome, WiFi Calling will also work in the bargain.
If only you know how to go to the hidden menu on T-Mobile and enable Port Check Test there. I don't know, but most likely differently than at AT&T.
Thank you.

I dont think there will be a way to fix that, try look for a guide to get your efs backed up. EFS contains your devices imei, radios etc (sensitive information) likely using someone elses will duplicate their efs and will make their device not work or create later on issues

I have an AT&T mobile variant. But I've never rooted before, and my phone has yet to be installed within AT&T sim card. I assume this doesn't matter since while I'm doing all this the sim card is out, but I wanted to make sure.

After reading what KouaV1 said, I'm sorry, but I'm going to have to retract my offer.

Tried using efstools, even after specifying the COM port in the dll.config the critical error persists. Does anyone have an idea how to deal with this?
