Convert H990DS AME to AU and get VOLTE (Root)

Hi there,
First, my apologies for my English ( I am not English native speaker) anyhow,
Today I managed to change my LG V20 H990DS AME ( Middle east ) to AU (Australia).
And one of the bounces I got is VoLte icon (Still didn't confirm if it is actually working)
The procedure doesn't require to flash a new rom, all what you need to do is the following:
- go to the root and find the folder /CUST (Use any root explorer)
- Open "open_path_mapping.cfg" and "op_list.cfg"
- You will see AU and AME have unique values ( in my case 57 for AU and 71 for AME).
- in both files write AU value for AME and vice versa.
- do factory reset ( all AU APKs and frameworks will be installed automaticly instead of AME stuff).
- once your mobile opened, in initialization wizard, Australia will be the default country.
- You will find the VoLte in the hidden tiles.
I am still exploring new changes.
Wish you all the luck.
Regards...
Note:
- This is experimental procedure, do it on your own responsibility.
- You can backup all your apps and files using LG backup, and you can restore them once the procedure is done.
- Same procedure can be done to all LG V20 phones

Wouldn't it have been easier using KDZWriter?

This is only sn alternative way of doing it.
Moreover, KDZWriter didn't work in my case.

why do you need volte in middle east anyway ?

I don't understand the reason for this question, but the answer, because most of the mobile networks here support VoLTE.
H990DS for GCC doesn't support VoLTE.

yeah i know they support ... but what is the actual advantage ... i dont see it sorry
if you know what kind of applications for this volte service let me know

I assume that the OP is living in India, and an user of Reliance Jio. In case you don't know, that particular Indian carrier only has 4G bands, so if your phone doesn't support VoLTE, you won't be able to make calls at all on that carrier.....
Not without Jio's app I guess. But everyone seem to hate it.

I dunno, cost-cutting I guess since Jio has some of the cheapest plan in Inida. You're welcome though.

Did it work for you?
T-Mobile US H990DS user here, I converted to ESA instead of AU and have not factory resetted (is it really necessary). I also edited my MCC and MNC into the config files for ESA and the icon does show up but IMS never connects.\

Yes, it is required to do a factory resit, as e.g. some of AME apps are different than AU apps and those apps will be installed during first run after device format.
In your case the information only will be cganged, but not the apps as well.

What partitions do I format and can I keep my internal storage if not my apps?

TO be hones I am not sure, please check yourself if formatting "Storage" partition is the one. Of course all your data will be deleted. So, in all cases back up all partitions using TWRIP and move your data to external io external flash before proceeding.
You may also use LG backup, to back up all apps and their data, so after formatting "Storage" you will be able to restore all apps and their data.
Please do a little search about this procedure.

My cell number is from "Zain", in Zain they allow Wifi calling and VoLte for Iphones only. So I didn't test that.

Ok. Are you able to see the options in the call setting to enable advanced calling /Volte?

VoLte is not there, I found it only in the main sliding menu in the main screen.
https://ibb.co/jx6rFo

Ok. Sometime back I also managed to enable the hidden menu options (ims)with lots of XML edits in cust folder and a factory reset. But volte never connected. Also the options were not visible in call settings menu. I had to stop testing as this was my main device. Need to test more but the factory rest is keeping me from doing it.
Would you know any region which has VOLTE enabled by default for global carriers? I could try flashing the cus partition and see. Mine is sea. Only has official VOLTE enabled for SG and TW carriers.

Visible Wireless and Custom Roms

Has anybody gotten visible Wireless to work correctly on custom roms? I got it up and running no problem on oxygen OS, but for some reason I just can't get it going on customs.
It's literally driving me insane.

I'm bumping this thread... been trying out some custom roms (Havoc and trying Bliss now) but haven't been able to get any Visible Wireless (by Verizon) signal on my phone.
Does anyone know if ANY custom ROM works? Particularly interested in ASOP ROMs, not ones based on OOS.

Yes, you can get visible wireless to work on all custom roms now. Used to not be able to because custom roms wouldn't detect Verizon Sims, but that's been fixed for a couple months now. Only thing that needs to be done is updating the apn config. The instructions to replace the apn config file are located here. The only difference is on Android 10, it's located in /system/product/etc/ instead of /system/etc/ that is lit used to be on Android 9. I've uploaded the new apn config file that you need to use.

Wow. I just got a H830 unlocked lg g5 running lineage 17.1 working with visible LTE. I merely switched the apn.xml file as you said and switched my preferred network mode to LTE. THANK YOU!!

Yes!!! I finally did! Lineage 17.1 on a lg g5 h830 and on lineage 17.1 galaxy s9. Both working. WOOHOO! Merely swap apn.xml, chmod, reboot, reset settings, then click visible internet, then set network mode to "LTE"

I have a OP8 Pro that I've been trying to get work with Visible and custom roms (Resurrection Remix and/or crDroid specifically), but have hit a dead end.
crDroid doesn't let me edit any of the "Network Settings," the option is grayed out entirely with the Visible SIM inserted (but the lock screen shows "No SIM inserted - Visible," giving the impression that the phone sees the SIM in one slot, knows it is Visible, but won't connect or register it to allow changing settings).
Resurrection Remix will recognize the SIM, and I can get into Network Settings. I've tried to add all 4 APNs manually after flash and can't get it to get a signal at all, leading me to believe that there's further, "deeper" integration that I don't have access to after flashing is complete and system partitions are locked as read-only.
TWRP 3.40-14 by mauronofrio works with Resurrection Remix flashed, but System, Vendor, Product, etc. are all locked as read-only, so editing the apn-conf.xml file can't be edited. And, sadly, that's where I'm at. A bit frustrating that OOS stock recognizes everything instantly upon initial boot, but custom roms won't. If there's any information I can provide to help get universal support for this carrier, I would be more than happy to help contribute.

I have a Pixel 4a and none of the custom ROMs except 1, which naturally was the last one I tried, worked. The ROM that worked had this dir /product/etc/CarrierSettings/ with a config for each carrier, Visible's config filename being visible_us.pb, and this dir was missing from the ROMs that Visible did not work on. Note the stock firmware had the same dir and Visible config as well. I also have /product/etc/apns-conf.xml in my ROM that works on Visible but the Visible APNs are NOT in that config so it's pulling it from the visible_us.pb.
It's clearly a firmware issue on some level. I suspect it's simply a matter of getting the system to use the proper APNs. It seems to me that the only way to do that is by building the ROM with the Visible APNs baked in the /product/etc/CarrierSettings/visible_us.pb, or /product/etc/apns-conf.xml, depending on where your implementation gets these default values from — or maybe it's the implementation that makes the difference, I'm not sure.
What doesn't make sense to me is why adding the APNs in settings manually had zero effect. I got the same default APNs to select from when I insert the SIM with ROM that did not work as you, StraightTalk, Verizon, and Xfinity. I also noticed that intermittently it would automatically load the VSBLINTERNET APN from the SIM but nothing would work.
I think the next step is to try to get the devs to include the Visible APNs to apns-conf.xml in the next build. I suspect that will cure this. Too bad Android make the system RO or it would be trivial.
Links that may be of interest..
This is my ROM for Pixel 4a that does work on Visible forked from ASOP.

This was extremely informative! Hopefully this will be helpful to somebody else seeking the info and scouring the web for answers.
I'm on stock OOS right now on an unlocked OP8 Pro. There is no CarrierSettings on this rom, so maybe it's just the APN file? I couldn't find a visible_us.pb file either. But I've also had a dev whip up a Magisk module that supposedly added the APN settings in, to no avail. Perhaps "baking in" is different than trying to overwrite via Magisk.
Of course, I say all of this pleading ignorance to what may be obvious to actual contributors. I have virtually no idea what I'm doing and am probably talking out my ass.

Old thread but I am just discovering (via Oxygen Updater) that the IN2015 I purchased from eBay thinking it was a US Open model, not a Visible Frankenstein's monster, will not update from 10.5.4 IN68CE via Oxygen Updater in April 2021.
I just canceled eBay return (128GB was listed as 256GB) but kept based on like new condition and assuming I could easily bootloader unlock, root, flash International Oxygen 11 and use dual SIM tray (eBay order).
Wondering if anyone has successfully updated (via fastboot flashing) a OP8 Visible version to a true carrier free model.

I sold mine and went for the 8 pro, so I'm not aware of anything. I couldn't get it to do anything but run the visible software, unfortunately.

Bummer! Before I follow up my recent eBay return of the blacklisted OP7 Pro I received with a return of this, I guess I'll get familiar with MSM Tool and try to flash different versions of Android 10 and see if I can get something running that I can upgrade. I need non carrier restricted OOS so it will recognize two SIMs. Question is if I can even utilize 2 SIMs with a single IMEI device.
Looking like another eBay return is in my future.

Question Cross-Flashing Mi 11 Ultra (Snapdragon 888) - Lahaina Modem Image to ROG for more carriers compatibility ??

Hey Guys,
So along with my struggle of loading MBN files, I eventually used a Xiaomi Mi 11 Ultra (Global Edition) for a few days. This is another device that runs on the Same Snapdragon 888 SOC, and has the exact same Modem (Codename Lahaina). On the Mi 11 Ultra, Both my carriers have 5G / VoLTE working perfectly fine and had no issues whatsoever.
I opened up both the modem.img files (Can be viewed with 7Zip) and even the file structure is identical including the codenames, with the difference Xiaomi modem having more MBN files for many more carriers (I posted the MBN file extracted over here), (including the two MBN files my carriers use). On the other hand ASUS Modem.img has a very limited number of MBN files, which looks like they haven't updated it since the summer of 1969.
This is the Xiaomi Mi 11 Ultra Modem.img
File on MEGA
mega.nz
This is the ZS673KS (ROG 5) Modem.img
File on MEGA
mega.nz
Since there is no way to upload MBN files to the ROG 5 - Does anyone know whether we can fastboot flash the Modem image ?

Modem can be flashed over Fastboot.
Not required EDL.
But need to verify whether this has any risks. Only the chip (SOC) brand is same, but internally there might be other differences, and the image sizes are not the same either. So worried of hard brick.

BLOB images have the same code but very different interface to the kernel in most cases, so it's not likely anything will work

No pb! The main issue now that I have volte working along real 5G on both sim slots, is vowifi... PDC was the ideal method, but if sysprop vendor.usb.diag 1 command triggers correct diag mode, then for sure is another issue here, A11 related I guess...

How did you get VoLTE working?
Did you have the MBN inside already?
PDC is sadly blocked in A11 OS mode. However OnePlus Users They have a FTM mode - Which allows Efs tools / PDC to communicate. Hopefully something should come around for Asus.

You need root first of all.
There are 2 ways for permanent volte/vowifi toggle menus:
1. *#*#4636#*#*, set preffered network type NR/LTE, then back to original.
2. Magisk module Pixel5_VoWIFI.VoLTE_magisk_module_V1-MINI.zip (search github)
After this, via EfsTools method just copy to NV your carrier mbn from attached folder, reboot. Tried all of them until found compatible one from my carrier but no VoWIFI sadly.

Which thread did you follow?
I had a problem with my device not connecting via WIFI.

Full support 5G+VoLTE+VoWIFI:
1. Flash last A11 firmware WW-18.0840.2201.229 and root it.
2. Through QPST and AsusVOLTE apk, connect via wifi /same IP option ( I used IPV4+IPV6).
3. Download and unrar attached EfsTools, which contains the mcfg.mbn** and load it to NV.
4. Flash A12 firmware WW-31.0810.1226.57.
5. Root again, install voenabler*** module in magisk, restart.
**A11 banner mbn in .rar is for GermanyVodafone.
*** voenabler or any other method you agree with for enabling 4G/VOWIFI menus in settings.
In A12 banner is HW_DEFAULT instead any previous A11 carrier specific mbn, which means that ASUS finally resolved this problem for good.
Later edit: will try to extract and upload modem.img already modded for easy fix this entire stupid issue which Asus could have been more responsive to buyer's needs ...
Enjoy!

Since after .77 update lost again volte and vowifi, so disapointed... Respawned .mbn and voila, back in time with only volte capability, no vowifi.
Because I don't want to get through previous posted procedure, as I would be stuck in .57 basically, I found an alternative solution that could offer updates advantages and minimum-hassle procedure for regaining volte/vowifi, which basically is copying working mbn unpacked files to efs partition via efsExplorer in QPST. I tried mbn from an identical X60 qualcomm/lahaina chipset (found on xiaomi12t) and volte/vowifi working again, but no 5G this time. Anyway, is a matter of pacience and time for testing.
Another solution would be modifying modem.img extracted from Asus payload.bin but I didn't found an easy way to unpack/repack, only managed to open it through 7zip and get some resources. If you can find a solution to this, I think this would be the most elegant way for us to have all modem's capabilities activated, by simply restore modified-modem.img after every update.
And yes, tried AIK, various .img unpackers etc...

First of all, thank you for the time and effort you put into creating this guide. It is really appreciated.
I have a few questions I need to ask, if I may:
1. What is the difference between your method and that other method on 4a 5G forum that says to just flash the magisk module? As I am currently running the second method I must say I do get 5g icon/speed and also volte/vowifi works ok where I live (Romania, Bucharest). However, I am aware I might be missing some features like 4G Carrier Aggregation (I think that is 4g+) and proper band allocation for 5G. Will your method unlock these too? Granted that I will need to use the correct mbn for my operator.
2. I read on your github description that the magisk module you mention changes some build.prop values. If I want to add/change more values besides the ones you mention, how can I achieve that? I have no technical knowledge on how to modify an existing magisk module..
3. If I am going to use your method, will it be required to repeat the qpst/efs steps each and every time I perform an OTA update?
4. Based of your method, how can I also unlock 5G access ? What additional files I need to edit in order to achieve this?
Hopefully you can provide some answers, for which I would be very grateful.

First of all, thank you for the time and effort you put into creating this guide. It is really appreciated.
I have a few questions I need to ask, if I may:
1. What is the difference between your method and that other method on 4a 5G forum that says to just flash the magisk module? As I am currently running the second method I must say I do get 5g icon/speed and also volte/vowifi works ok where I live (Romania, Bucharest). However, I am aware I might be missing some features like 4G Carrier Aggregation (I think that is 4g+) and proper band allocation for 5G. Will your method unlock these too? Granted that I will need to use the correct mbn for my operator.

About the guide - no problem. I just want to share knowledge
1.) The difference is that I'm modyfing(in fact reseting) only the necesary props and adding selected MBN to the modem partition. Module mentioned "overwrites" the system MBN's, while I'm adding a new one directly to the modem. Also, this module modifies a lot of props and resets them to specified values - I'm doing only the necessary ones.
Currently my method doesn't unlock 5G - but also on the same page(4a 5G) they've used the same method.
I've just copied all the details into single guide, so everyone, who wants to have a working VoLTE and VoWiFi can use my guide without searching whole forum for posts etc.
I've tried to use this Magisk module, but it didn't work with my country(Poland) with my operator(Orange) - so I'm using this method. It should work on pretty much every Android version, while I can't guarantee that the mentioned module will.
2.) If you want to edit more props, you can add them to my module or create your own.

Topjohnwu have a great guide how to do it and how to build your own magisk module.
3.) Yes, you need to do it after OTA, because OTA is updating modem partition and overwriting changes.
4.) I don't have access to 5G right now, but @Kars88 wrote it perfectly:

Update (9 Oct 2022): Upload module here. Update (7 Apr 2021): If you are looking for the manual way to add 5G support besides the magisk module way or the module does not work for you. Please refer to #54 for the detailed steps. Thanks again to...

EDIT:
Btw. @mightyvenom Thanks for reminding me about that module, probably I'll create my own based on the one that you've mentioned - I just saw some new flags, that may be helpful with my research

Thanks for your answers. I will try your method and compare the results with the initial solution I have found.
Let us know if you make any progress in changing the magisk module from the Pixel 4a 5G forum. I am particularly interested to achieve 4G CA more than 5G to be honest, maybe this is doable.

@mightyvenom
It should enable CA(I guess), because you're essentially loading a proper MBN for your network provider - those files contains data about CA. At least in Poland it works.
nothing done on my side yet, when 2022.12 update will be out I'll try to create a proper Magisk module and share results.

@mightyvenom
if you want, you may test out this module.
It it unfinished, todo:
- fix path for MBNs,
- new github repo,
- test for 5G(need to retweak system.prop).
I've added two props:
persist.vendor.radio.mbn_load_flag=3
persist.vendor.radio.mbn_wait_s=60
I've flashed November Full IMAGE(without deleting data), applied Magisk, applied this module and I got VoLTE&VoWiFi (in IMS it is registered).
If you didn't the method with flashing through efsTools.exe it should enable you a VoLTE/WiFi.

I read here https://support.google.com/pixelphone/answer/12240791?hl=en that they have added volte support. But it seems like many people still do not have VoLTE. I am so confused.

I'm not sure, that done right, after your last post, but after placing latest module to magisk - nothing has changed. I see an option to enable volte/vowifi, but still no success with calling. After making a call it still switch to 3g/hsdpa. I'm on pixel 5 and tmobile (pl).
Is there still needed to create an mbn file with efstool?
Edit
I've solved with this thread https://forum.xda-developers.com/t/module-to-enable-5g-volte-vowifi-on-pixel4a-5g-pixel5.4207725/ just to let you know, for me works only applying magisk module . Really not sure why, because I haven't apply mbn file. But as you can see here - I can call over LTE and my phone is registered https://101010.pl/@inzaghi89/109661148495494919

I appreciate the work you've put in, but I'm finding the instructions a little unclear. Could someone please give another description of the process to follow? Thanks in advance.

[MOD]MagiskModule - VoLTE & VoWifi & 5G in unsupported countries | Pixel 4a 5G & 5 & 5a
Introduction I would like to share a magisk module, which: - enables 5G, - enables VoLTE, - enables VoWiFi, - loads MBNs properly after loosing connection with network provider, - does not enforce 5G. Module is created by me, latest release...

It should work for you as this is Magisk Module only

its not working on my P5a using indonesian carrier telkomsel.

Replacing a modem mbn file

I know it's possible but I'm not sure how to do it.
The Verizon modem file is loaded with coding to disable 5G, I know for a fact it has at least 2 methods to disable 5g, I found a way around those but still can't get it to connect to 5g but it sees the 5g is available. Which is the step in the right direction as stock mbn file with no mods results in the phone never seeing 5g as being available period.
So what I'm suggesting might work is swapping the Verizon modem mbn file with one from a phone that works on Verizon's 5G,like a s20 or similar or perhaps the Verizon's UW model also(heard the chipset needs to be the same on the device's)
Can anyone assist? Or point me in the right direction???

I think I have the same issue now. Verizon, I assume, somehow disabled the 5G functionality after some sort of update and I can't get it back. I use T - Mobile.

this may help https://forum.xda-developers.com/t/guide-fix-enable-5g-and-dss.4206461/ (look in other OnePlus phones like 10 or 8t )

After a bit of trial and error, I got 5G to work again on my device (IN2019). I had to replace the carrier_policy.xml files with another one from XDA in order to enable the network again.

@intheb0x Have you found a solution to this? I am interested in the same thing, I have a Korean S20 that does not have the info for North American/US NR5G bands. Other than software/firmware differences the Korean S20 is identical to the US versions, even the pit files are the same when examined with PIT Magic.
I've unpacked various modem images from XAA and TMB roms and then compared to Korean (KOO) roms and found the 549_10_0.mbn and 549_11_0.mbn to be missing a lot of data on the Korean roms. Looking at these files with a hex editor I can see that the US roms definitely have information regarding additional bands.
I have tried copying over the files and repacking the modem.img but the phone fails to load the files I copy. I believe this is because they are signed with a different signature than the Korean files.
I'm wondering if there is a way to disable signature verification on the modem files, maybe something like this?:
[Magisk MODULE] Patch SecureFolder - Disable Signature Verification - Flag Secure - Biometrics after reboot
SAMSUNG GENERAL PATCHER V2.2 SUPPORT: TELEGRAM CHANNEL - TELEGRAM GROUP - SUPPORT ME ABOUT THIS: Magisk module to automatically patch the services.jar of Samsung devices, based on Dynamic Installer The compatibility is relative but Android...
forum.xda-developers.com
I know I can edit the policy.xml with tools like QPST, EFS Explorer, QFIL but I have yet to find anywhere that I can load the additional info for these bands.
Any help would be much appreciated
