Volte support Lg v20 h990ds

[tickertapes]

I have checked and nothing happens. I am using an EE sim in slot 1 and iD Mobile (3 network MVNO) in the other, can't enable the VoLTE on the phone. Also EE do mention that Wi-Fi calling works on phones bought directly from them. I know these services are different lol

To access the UK's VoLTE network, we will have to root and copy carrier configuration files from another UK LG device. An LG G6 bought in the UK may be viable.
It's a shame, this is such a lovely device from a hardware perspective, we just need some help with the software.

Judging from another thread, root is very complicated on this device. It's there a way you can edit system files without a custom recovery using adb?

You are absolutely right on the hardware side. On the rooting side of things, I am not really a hardcore tinkering man. However, I am willing to try it out. I bought this phone mainly for music purposes and obviously communication

Can someone post the VoLTE files for either the US996 or an H990DS with VoLTE since I'm in the US in case I decide to root? Thanks to anyone who does!

Support for VoLTE was successfully added to the G4

I'm sure its possible with the V20

what will be the best official rom for the H990DS in general?? VoLTE is a nice feature so is wifi calling but man I wish it was that simple to get it. I am a novice lol

Hello greetings from Portugal!

My device:
LG H990DS;
Model Region: ARE (Mid. East/AfricaAE/United Arab Emirates)
Software: V10g-AME-XX

After a few hours searching and flashing singapore and phillipines roms volte icon didn´t appear... Using LGUP to flash these rom´s only possible with upgrade option and not reburbish... After the flashing 3 or 4 error windows appear, saying that MCC and MNC (NT CUST) don´t match with my version (open_ame). However the phone works with no issues. With these rom´s using quickshortermaker i can find volte feature in hidden menu, but can not activate...

But the most surprising thing is that in this post i saw screenshots with the 2 sim´s mobile data activated simultaneously... even with original rom i can activate just 1 mobile data at a time...

Called vodafone portugal carrier and they said to me that volte is enable on my sim card... so the issue is my phone!

Maybe there´s a way by rooting phone, but too risky and with no guarantees that volte will work...

I installed LGup and flashed it with the phillipines rom. My phone still says V10e-TWN-XX in the SW info but I have VoLTE support now, weird or what.

Anyone else wishing to give this a go will need to install Lg Bridge from the LG website which comes with the required USB drivers, then install LGup (LGUP_Store_Frame_Ver_1_14_3.msi) found here https://www.mylgphones.com/download-lg-up-software. You will also need a DLL (LGUP_Common.dll) for the H990DS https://drive.google.com/open?id=0B0-_MIhGeuKhNWFpcUNfc2FKeG8, copy this to C:\Program Files (x86)\LG Electronics\LGUP\model\common\ after installing LGup. if the folder does not exist, create it. replace the existing file with the one in the link. the one that comes with LGup will not work.

The LGUP_Common.dll here is the only one that worked for my H990DS. I am trying to change to the Singapore ROM since it is the most updated one.

So, living in the US and wanting VoLTE, can I copy the cust from a US996 that supports VoLTE with T-Mobile or would I end up with a brick? If someone could be kind enough to post the cust partition of their US996 I could try and see if I could copy the VoLTE config files to my H990ds to see if TMO VoLTE would work.

i am using H990DS phone with H990N firmware (201612 version).
Rooted, VoLTE, VoWiFi works fine here.

A bit late, but if you use a terminal and mound /cust as rw, you can edit the files directly for ESA, AME, etc.

I figure out how to fix this error on non-rooted phone: Current version is not available for user. Can't find matched cust for NTCODE=[,]
This is good explanation, thanks to GuestK00280, but solution require rooted phone

I dont root the phone, I am flashing stock firmwares only, and don't have any root and bootloader is still locked.
So basically what is happening the phone is verifying the country code folder, but because I flashed firmware for different region, my country code doesn match to the country code into firmware.
For example, I flashed with patched LG UP 1.14.3 my phone with Taiwan original stock rom, I put Singapore firmware (H990ds10i_00_OPEN_SG_DS_OP_1117.kdz)
I fixed the error like this:
1. With LG Firmware Extract 1.2.6.1 convert .KDZ into .DZ
2. extract .DZ into .bin files
3. open cust_xxxx.bin with notepad, and search for „/cust/“ You will find the country code like this:
FFFFFF,56=/cust/OPEN_COM_DS
4. So 56 is the country code of the Singapore stock rom. OPEN for operator - which means any operator. COM for country - which means any country
5. on the phone go into service menu, for LG 990DS is *#546368#*990# -> SVC Menu -> Version Info -> NT Code
6. The line may look like this
"0","FFF,FFF,FFFFFFFF,FFFFFFFF,FF"
or
"0",
7. edit the line to look exactly like this
"1","FFF,FFF,FFFFFFFF,FFFFFFFF,56"
8. restart.
9. after restart the error is gone
10. factory reset and restart.
11. after restart all previous Taiwan bloatware is gone, and get replaced with Singapore bloatware. So now I flashed completely the Singapore stock rom.

Flashing Taiwan stock rom with Singapore stock rom made VoLTE button to appear in the draging top menu above notifications
I use this method on every stock rom from any different region, and my phone is never been rooted yet
Btw, I found in cust_xxxx.bin country code pointing to something interesting:
999999,99=/cust/SUPERSET
I wonder what will happen if I put instead 56 a country code 99? What stock rom will see after factory reset?

Hi,

it doesn't work for me....it keeps showing the same error on powering on the phone. When I try to change the NT code, it says NT code write error.
