Three UK HD Voice Help Needed - Galaxy S III Q&A, Help & Troubleshooting

Ok thought i would post my own thread to see if anyone can help me.
I have a S3 from Three UK. Was running on stock Three rom. I flashed it with the latest non branded S3 rom. Now the WB-AMR setting is off and i cannot turn it on even though it was on as default in the Three branded rom.
What i want to know is will the WB-AMR only be switched on on the Three branded rom or could i for example keep the unbranded rom but flash the Three CRC to get the hd voice enabled? Or is this setting contained within the actual rom itself, therefore i would need to go back to the branded rom to obtain the hd voice? Im slightly confused. Any help appreciated.

CSC can be flashed as standalone. See the rom guide.

Sorry i already know this (should have said) but is the HD Voice option stored on the actual rom or the csc? Dont want to flash the CSC to the stock branded Three rom incase it doesnt work then i have to install everything again. What exactly does the CSC do?

Probability is that the network have put any add ons in the cache file part of the CSC file .
CSC files can be opened for a look see .
Cache extractor post in dev section probably .

Opened a 3 CSC and it shows as below in part other networks have no mention of WBAmr .
It also has an MH 20 -ICS-HHp application in the add on apps folder .

So would i be correct in thinking that flashing the original Three CSC will give me back my HD voice and i can use this in conjunction with the latest unbranded rom? If i done this would i be able to continue to get updates via Kies or OTA or would this cease seeing as im not using the supplied CSC with the rom?
Thanks for your help btw. Appreciate it :good:

Ok i flashed the stock Three CSC but when i go into change the CSC it still lists the same options as before. I.E BTU,CPW,DBT,ITV,KOR,XEF,XEO.
Phone is still on CSC I9300OXABLG8. Im even more confused now.

Ok spent more time with the phone and managed to get the Three CSC onto the phone with the latest unbranded firmware. It didnt however re-enable WB-AMR (HD VOICE) so i flashed it back. It would appear that it is enabled in the rom. Why it isnt enabled as standard i have no idea seeing as the phone supports it.

What are you doing to check and enable the setting? And did flashing the CSC wipe your device?

I don't understand why Samsung have disabled WB-AMR on unbranded devices.
The hardware obviously supports this feature, so why not at least have it as a settings option? Most networks here appear to support it.
I'm also with THREE UK and I'd like to use HD-Voice, but WB-AMR is disabled.
The phone is smart enough to load all the other settings (e.g. service centre numbers) related to my network, so why not WB-AMR?
Yes, I know I could flash a different ROM, but I don't want the operator bloatware or any theoretical risk of losing warranty.

I was going into the service menu via the code i found on here. There is no option to turn on WB-AMR. I can see the menu but pressing Audio doesnt do anything and when i go into the WB-AMR menu it is turned off with no way to re-enable it.
Flashing the CSC did wipe my device.
Im still waiting on Samsung to get back to me. Over a week now with no reply from them.

What code did you use to bring up the service menu. Im on a JB rom and the ones i've tried give the error "Connection problem or invalid MMI code"

1-be sure that THREE support HD Voice
2-flash the latest THREE stock rom
3-root it
4-copy the /system/csc folder and the /system/SW_Configuration file to your external SDcard
5-remove all the bloatware apk (also look for branded bootanim, ringtones, ...) from the csc folder on your external SDcard
6-flash the stock rom you want
7-root it
8-delete all the content of your /System/csc folder
9-now push back the content of the folder and the file you have previously copied on your external SDcard
10-now you have to make a hard reset to aplly the CSC settings. There is 2 way for that depending on what was in the THREE /system/csc folder
10a-first way: open dialer and dial *#272*YOURIMEI# and select your CSC and hit "apply"
10b-second way (only if first one does not work): restart in recovery and make a factory reset
11-you're done
You should now be with your unbranded rom without THREE customization but with THREE csc settings (APN, HD Voice, Fast Dormacy, ...)
I do that on my phone and I now run Stock XXBLG8 with SFR (french carrier) settings and no bloatware or customization

Thanks Mopral i had seen you posting that in another thread but it isnt suitable for myself. I dont fancy having to do that everytime a new firmware is out , i quite like getting OTA updates with limited hassle. It is a solution but one we shouldnt have to do considering the phone and my carrier support HD voice.
*#197328640# is the code i used to get into the service menu. Im still on ICS so no idea if it works with JB.

There has GOT to be a way to turn on the setting without flashing CSC....

Not sure...
It seems that there is no access to this settings on the SGS3
So until someone find a solution, there is only the hard way...

From the Three Website:
What do I need to get HD Voice?
HD Voice capable phone
A phone that originated from Three (unlocked phones now being used on Three won’t work)
The latest phone software available
Calling on the Three network
Although I do agree there has to be an easier way to enable this if anyone knows could you please pm me. Thanks!

Apologies for the bump, but this has been a VERY useful thread for me today, and I wanted to add something.
I had been using CM10 for a while which supports HD voice without any issues (CSC is only for Samsung ROMs) but then I moved to Omega ROM for various reasons, and the one thing I missed was HD voice.
I managed to get it working, based on Mopral's excellent steps below, but without wiping my internal memory and also without wiping data.

Here's what I did:
1. Used the code *#197328640# to get to the service menu. [8] WB-AMR Status showed "WB-AMR Setting: OFF".
2. Did a nandroid backup of my current Omega ROM v30 (DLJ2) setup using CWM Touch 6.0.1.2.
3. Flashed the I9300XXDLJ1 Three UK official stock Jelly Bean release found in this thread using MobileODIN (checking all EverRoot and SU Injection options).
4. Using Root Explorer, copied /system/csc folder and the /system/SW_Configuration file to my external SDcard.
5. Did a nandroid restore of my current Omega ROM v30 setup using CWM Touch 6.0.1.2.
6. Using WinRAR on my PC, I created a copy of the Omega ROM v30 zip file and deleted the contents of /system/app. Then I dragged and dropped the files from my external SDcard into the zip file to this location (using the "Add and Replace" feature of WinRAR). Did the same for the /system/SW_Configuration file.
7. Flashed this new customised Omega ROM zip over the top of my existing setup that I had just nandroid restored. I did NOT wipe data.
8. After booting, I used the code *#197328640# to get to the service menu again. [8] WB-AMR Status now shows "WB-AMR Setting: ON". Rang my wife on her S3 to test it, HD voice working perfectly!
I hope somebody finds this useful.

I have flashed the official 3 JB ROM using ODIN, so have the 3 CSC. I did not wipe. However, HD-Voice is still off. If I do a factory reset, will it get switched on?

How to add HD Voice (G.722) to stock XEU ROM?

I have just debranded my stock firmware from ORO KH1 to XEU KF3. After doing this I noticed that HD Voice, a service which Orange is very much proud of, stopped working. HD Voice basically uses a better codec (G.722?) when both the caller and the receiver have this codec available and are within 3G coverage. When I debranded my phone using the XEU CSC this stopped working and I want to know if there is any way to install it the same way as it is included by default in the ORO CSC.
Thanks.
I don't see how this is even *remotely* related to Original Android Development, but anyway. How about flashing the ORO KH1 CSC on top of KF3? Does that "brand" your phone again?
I debranded my phone to get rid of all the customizations that are applied with the ORO CSC (included trials and demos for various crap games, different launcher, etc). I just want to find a way to add this codec to the stock Samsung ROM.
The CSC files does not contain trials, games, bloatware, launchers etc. It just contains network parameters set specifically for your region/network. ORO, i suppose, is the CSC file for Orange. It will not be readding any of the old applications back.
I was under the impression that a CSC does exactly that. Taken from here:
CSC is the consumer software customisation and is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and also APN settings for data connection, MMS etc for your service provider.

I don't want to have any carrier branding or custom software, but I'd like to be able to use HD Voice. Is there any way to include just this voice codec?
It contains no software and is just a few text and xml files that basically give a list of network settings . CSC is not a must have no CSC = manual network set-up .
Easy enough to pull CSC folder and other CSC files out of your phone all in System .
jje
I have compared, out of curiosity, the sizes of the XEU CSC and an Orange CSC. They are 27 MB vs 52 MB, so I realize those CSCs include a lot more than just XML files and settings.
I do not want to use the Orange CSC, that being the whole reason why I debranded my phone, so is there any way I can re-add the HD Voice codec to the phone without adding the whole CSC?

If you say the CSC has this software pull it out of the Orange CSC.

I am not saying the CSC has it because I have no clue how to extract the contents of the CSC, and even if I knew how I wouldn't know which files were needed, that's why I am posting here.
Any idea how to do this without installing the whole ORO CSC?
have you got a link to the orange csc file? or can you just put orange stock firmware in csc box in odin to just flash csc?
Here's the whole ORO package, includes the whole ROM (courtesy of Intratech):
http://www.multiupload.com/YOZ2HJOX4D
I don't want to flash the whole ORO CSC because that would add all the junk that comes bundled with the stock Orange ROM.

is there a way to just flash the csc part? tried picking the file from csc menu in odin but it installed the entire rom
quite interesting topic.
my carrier is also giving this service. N8 owners can use it.
can orange branded s2 owners check their devices? (any different apn setting etc.)
I had an Orange branded ROM and had HD Voice working. APNs are the same, so I don't think that's the difference.
Seems there is no CSC needed. It's just a hidden option in the service menu
Dial *#*#197328640#*#* -> [5] Audio -> [7] WB-AMR SETTING -> [1] WB-AMR ENABLE -> reboot

How can you tell if HD voice is available. I am with Orange but bought an SG2 from Amazon. I have flashed non-wipe KI3 to it.

[GUIDE] How to fix "unknown baseband" / "stuck on airplane mode" problem

[GUIDE] How to fix "unknown baseband" / "stuck on airplane mode" problem
Today my friend who has a i9100 as I presented the unit with the following problem: not connected in any way in the mobile carrier, airplane mode was stucked.
Well, looking on the internet and especially this forum, I found several solutions to make the flash the original rom to accept that his incredible Samsung Galaxy SII had become an amazing Samsung Play SII. As I'm Brazilian and never give up, here's what worked for me.
---------
Most importantly, use at your own risk. If you are unsure of the steps below, do not do or have someone who has more experience. The procedures worked for me, but does not mean it will work for you.
Special care was always doing this kind of operation in any type of phone: use good quality cables, make sure that there is no bad contacts and preferably make the flash operations with a notebook with the battery at 100% load and phone with 100% load. After all, nobody wants the operation is interrupted and you get a plastic brick.
----
Here are the steps:
1) Download this application: http://forum.xda-developers.com/showthread.php?t=1308546. EFS Pro serves to backup / restore partition EFS.
2) To use EFS Pro, your phone must be enabled with the root. To do this, follow:
2.a) Paving the way for SuperOneClick: http://forum.xda-developers.com/showthread.php?t=1056334
2.b) Using SuperOneClick to "open legs": http://forum.xda-developers.com/showthread.php?t=803682
2.c) Now, some screwdrivers and screws inside your device: https://market.android.com/details?...t=W251bGwsMSwxLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.
3) Now the easy part, get another Galaxy S2 to be the "donor" baseband. You do not? Download mine by this link:
https://hotfile.com/dl/149885347/a004c04/EFS_20111227_235358.tar.html or https://rapidshare.com/files/2401446638/EFS_20111227_235358.tar. If you use my baseband, skip to step 3.b.
3.a) Pick up the phone "donor", run the EFS Pro and select the backup option. To accelerate the process, ask to put the backup on the sdcard. There, he set up and placed in the / sdcard / EFSProBackup.
3.b) Copy / Create the folder / sdcard / EFSProBackup problem to the phone with the same path.
3.c) EFS Pro back in, ask to restore the backup from the device (will find the file you copied) and ready.
4) Give the problem phone a boot and see the problem disappear.

This is my first post and hopefully it will be useful. Pay me a beer if you like it.
Hi, ljlima,
thanks for your report, I'am Brazilian too, but I'm almost giving up
Completely disappointed with this ****ty problem... Made a hard reset typing a code in phone keypad (since I could not access ID samsung in factory reset) and nothing...
Very afraid of following your instructions since I'am totally newbie and there is no replies confirming your method.
Is there a chance of solving this by upgrading android version (although KIES is crappy as hell) or other non invasive and easier method ?
thank you!

Also, sometimes, if your /EFS is not totally corrupted, you can just reflash your modem. I had issues with this on CM7 nightlies, and my problem was always solved with a simple reflash. Its easier than restoring your whole /EFS backup, and a lot quicker. But, mind this is only if your /EFS isn't done for.
Thnx a lot. for refreshind download links.
any one confirm the success of this method?

This worked for me!!! You can find this software on net. Search with GSII_Repair. This works for sure!!! This can be downloaded from Google Play Market also. Available for free!!!

"lambergino" user tryed on january and works. And I wrote this post after resolve my friend problem.
"Unknown" baseband on a non-rooted SGS2!
Help!
My SGS2 suddenly would not recognize any SIM after a failed attempt at backing up my files using the sh!tty Kies software.
All I did was make a backup using Kies and somehow it got stuck "Preparing". I left it overnight and in the morning, when I checked, it still didn't go through the backup process - just kept saying preparing. Anyway, I decided to cancel it as I needed to use my phone already. I clicked on the cancel button and guess what? It also got stuck in cancelling! I left it and went to shower and when I got back after about 15 minutes (probably longer), it still didn't cancel. Frustrated, I plugged the USB cable out. Later that day, I noticed that I didn't receive any SMS/call. Then, I noticed that the notification bar displayed the "no signal" icon. I rebooted my phone, hoping the signal would return. But, I still got no signal after it switched on.
I did a factory reset, hoping it will put everything back to normal. I used the volume+power key combination as the factory reset option under Settings, somehow, would not work. Anyway, after doing the factory reset, it still wouldn't connect to the network.
I then noticed that the About screen displayed an "Unknown" baseband version.
From what I read from this thread and several other forums, this could be due to a corrupted /efs partition, which could have resulted from improperly rooting/flashing the device. However, I never rooted my phone in the first place!!!
And I heard the ICS update is rolling out now but I can't update because, somehow, Kies won't connect to my phone anymore!!!
My phone now is practically a very expensive music player. THIS IS SO FRUSTRATING!!!
Please help, anyone!
Hi there
I have a I9100G with missing IMEI and Baseband. Can I use your I9100 EFS file on my I9100G ?
Or is there someone who can provide EFS files for I9100G?
Thanks in advance!!!

Please try one these solutions

Most importantly, use at your own risk. If you are unsure of the steps below, do not do or have someone who has more experience. The procedures worked for me, but does not mean it will work for you.
Special care was always doing this kind of operation in any type of phone: use good quality cables, make sure that there is no bad contacts and preferably make the flash operations with a notebook with the battery at 100% load and phone with 100% load. After all, nobody wants the operation is interrupted and you get a plastic brick.

Here are the steps:
1) Download this application: http://forum.xda-developers.com/showthread.php?t=1308546. EFS Pro serves to backup / restore partition EFS.
2) To use EFS Pro, your phone must be enabled with the root. To do this, follow:

2.b) Using SuperOneClick to "open legs": http://forum.xda-developers.com/showthread.php?t=803682
2.c) Now, some screwdrivers and screws inside your device: https://market.android.com/details?...t=W251bGwsMSwxLDEsInN0ZXJpY3Nvbi5idXN5Ym94Il0.

3.a) Pick up the phone "donor", run the EFS Pro and select the backup option. To accelerate the process, ask to put the backup on the sdcard. There, he set up and placed in the / sdcard / EFSProBackup.
3.b) Copy / Create the folder / sdcard / EFSProBackup problem to the phone with the same path.
3.c) EFS Pro back in, ask to restore the backup from the device (will find the file you copied) and ready.
4) Give the problem phone a boot and see the problem disappear.

Will this work in Germany? I have the same problem. Can I use your baseband since I dont have a donor Handy SII? I have been racking my brain for 3 days trying to correct this.

As I said, try it on own risk. But I think that will work because other international users tried and worked, as you can see in this thread.
Good luck.
Donor EFS backup file needed..
Hi, I need a donor file compatible with EFSPro the links given in OP post have a .tar file whereas the latest version of EFS Pro works with a tar.gz with .img file in it.
I have also tried to replace the nv_data.bin file with the .bak version but the folder is Read only and I cannot over write the original file.
Any help is appreciated.

[GUIDE] H870 WiFi Calling enable on Stock based ROMS (Fulmics, etc.)

After over a week of trying, I've come up with a solution to enable WiFi Calling (probably also VoLTE) in Fulmics ROM for LG G6 and probably G5 running any stock based ROM.
THIS GUIDE WILL ONLY WORK IF YOUR DEVICE IS ON THE LIST OF YOUR CARRIER'S VOWIFI/VOLTE SUPPORTED DEVICES AND THE SERVICE IS ENABLED THROUGH AN OTA UPDATE FOR YOUR STOCK, BRANDED ROM PROVIDED BY YOUR CARRIER!
I don't believe in magic, you shouldn't either so don't think this guide will make VoWiFi/VoLTE work on your device regardless of your carrier's support for your phone model.
Also, if your provider offers VoLTE/VoWiFi through an external app available in Play Store, don't bother reading any further.
General idea described in this guide is to tweak your rom in a way that it is recognized by your carrier as their own VoLTE/VoWiFi enabled build that has a "green light" for IMS and Xcap apns registration in your provider's VoLTE/VoWiFi service. During my attempts you make the service work on my G6 running V10t based Fulmics ROM i discovered that adding IMS and Xcap apns plus getting all the IMS and GPRI VoLTE/WoWiFi hidden menu settings right is not enough. I had everything set up right and still couldn't make a WiFi call. Then it occured to me that maybe i can't make it work because Fulmics ROM is based v10t, and my provider's VoLTE/WoWiFi enabled rom is the v10h? So i tweaked Fulmics 1.6, then 2.0 so it masks itself in front of my provider as v10h while in fact it still is v10t Fulmics ROM 2.0. And guess what... IT WORKED!!! My Carrier's IMS and Xcap apns, manually added by me to the default open-eu apn list storred in /system/etc/apns-conf.xml, got registered in the service activating WiFi Calling on my device.
How to do it step-by-step guide below
1. PREREQUISITES:
- /OP/[YOUR CARRIER'S CUST FOLDER IN XXX_XX NAME FORMAT] in your main dir /root. If you only have OPEN_EU in your /OP you must get your carrier's specific cust folder or install Fulmics over your carrier's VoLTE/VoWiFi enabled rom then the cust folder you need will appear in /OP
- build.prop file from your Carrier's VoLTE/VoWiFi enabled rom for your LG model (make sure following line is in the file: ro.lge.cupp_capss.rootdir=/OP
- /OP dicectory in your device main root directory with your carrier's VoLTE/VoWiFi enabled ROM's subfolder (XXX_XX format). OPEN-EU or
GLOBAL-COM are not the ones .
- files from your carrier's rom: /root/data/ipsec/wo_apn.conf, /root/data/ipsec/wo/apn_xcap.conf
(You can try without those 2 files if you can't get them).
2. TO DO:
!!! AT SOME POINT OF CHANGING STUFF LISTED BELOW YOU WILL GET ALOT OF FC OF VARIOUS APPS. DON'T PANIC, JIST REBOOT YOUR DEVICE AND CARRY ON WITH CHANGES !!!
- in /OP directory delete folder _COMMON if you have one
- in /OP directory create a new directory called SUPERSET and set perms to 755
- copy all content from your carrier specific folder in /OP to SUPERSET. You can also just try renaming cour carrier's folder to SUPERSET instead of creating new filder and copying stuff to it.
- edit cust_group_mapping.cfg in /OP and change whatever you have after = to GLOBAL-COM
- open cust_path_mapping.cfg in /OP and make sure you have 999999,99=/OP/SUPERSET there on the list of providers
-edit official_op_resize.cfg and add SUPERSET_SIZE=[copy size value of your carrier's folder which should also be listed in the file]
-in /OP/SUPERSET (with your carrier's files coppied) edit cust.prop and in second line in the file change whatever you have after = to SUPERSET
- edit your rom current build.prop file and copy all additional stuff (in my case it was all the Fulmics ROM part of build.prop so from #Software Version down) to the build.prop acquired from your carrier's VoLTE/VoWiFi enabled rom. Add the coppied stuff at the bottom of the list.
- add following lines at the end of stuff coppied to your carrier's build.prop from step above:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1
wlan.lge.softap5g=false
# 2015-10-12 [email protected] LGP_DATA_IWLAN [START]
persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
Save the build.prop file and place it over your current system default build.prop. set perms to 644
- open your device's hidden menu, go to
Field Test->GPRI VoLTE/VoWiFi->UX and tick 3rd, 4th, 5th, 6th and 9th for WoWiFi only, all except 8th for VoLTE/VoWiFi and 1st and 2nd for VoLTE only.
- go to your apns in network settings and make sure you have all the apns needed (in my case the are: internet, mms, ims and xcap). If you don't have them, try sending settings request message to your carrier's apn service center, if that doesn't help, add the apns manually (you must find your carrier's specific manual settings on the internet). You can also edit /system/etc/apns-conf.xml file and add missing apns manually to the list in above file. To do that you must find your carrier's apns on the list first, (list order by MCC-MNC code) under your carrier's last apn enter your VoLTE/VoWiFi apns in the same way the other apns in the file are typed.
-save apns-conf.xml, go back to apn list in network settings, tap overview->restore defaults and the missing apns you added to your xml file should appear on the list in network settings.
-make sure you have all permissions right of the created/coppied/edited files and reboot your device.
When your phone boots back up to Fulmics you should have your carrier's boot animation instead of default LG one, then you should see initial boot screen with "android is setting up" for a couple of seconds, then your homescreen. When configuring of your sustem is done, open quick settings and your VoLTE and WiFi Calling tiles should appear there. Turn on what you want and test if it's working. Remember, with VoWiFi you must have both WiFi and WiFi calling ON. The easiest way to tell if WiFi Calling is active is the presence of a headphone with little WiFi icon on the status bar and other places in your dialer etc. To test, turn on airplane mode, wait till WiFi gets turned off, turn it back on in airplane mode, wait for WiFi calling icon on status bar and try to make a call with airplane mode on .
REMEMBER! This guide will will only work if your carrier verifies WiFi enabled devices by 3 conditions: 1. Device supported, 2. Apns present, 3. ROM build match (info from build.prop).
I might have forgotten about something (or not ) but will edit if or when questions start to be asked

@mrbeem tried flashing back the kdz trough lgup but in OP i found only three folders: _COMMON, lost+found and OPEN_EU, plus a lot of individual files.
Any clues? Can you specify what files the operator folder should contain? Thanks in advance!

What rom did you flash in LG UP? Was it your provider's stock ROM with WiFi Calling service enabled or was it Open EU rom? OP should contain your carrier's config files of you flash your provider's ROM. The files should be in a separate folder with your Carrier's name (for example, Vodafone Italy should have a folder in /OP named VDF_IT etc.). Carrier specific folder should contain subfolders called: config, overlay, apps, media, poweron, poweroff. Most impostant are: config and overlay. Also in /OP there should be 3 files apart from the subfolders: cust.prop, official_op_resize.cfg and except_buyercode.cfg
Pics of content of cust.prop and official_op_resize.cfg from my carrier's folder (P4P_PL)

The OPEN EU that Bridge downloads when my phone is connected, and is the same one which is referred as "Vodafone Italy" on LG Firmware.
In /OP i have these files: op_list, official_op_resize, custom_path_mapping, custo_group_mapping, client_id, buerycode, strangely are almost the same found on fulmics.
In Open_EU i've overlay and config folders, and these files: official_op_resize.cfg, except_buyercode.cfg and cust.prop.
The strange thing is that the vodafone brand remains also with the fulmics, in fact at everye clean installation i found vodafone apps and vodafone configuration before restore my lgbackup, what a mess lol

Ok so you have the everything. Just delete _COMMON filder, create SUPERSET and copy all from OPEN_EU to SUPERSET. Basicly follow the steps. Build.prop is most important part. Plus check if you have all apns needed for WiFi Calling, if not, add manually as described. It is a mess, but the key is to put that mess in an order that enables WiFi Calling. Carrier's boot animation on fulmics is a very good indication that you're on the right path to make it work. Just a small tip... Maybe start from the UI part to enable the ability to turn VoWiFi on/off and then the rest. This way you'll be able to see if or when your service becomes active. So.....
1. Copy this to your carrier's build.prop after you've coppied the Fulmics part:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1
wlan.lge.softap5g=false
# 2015-10-12 [email protected] LGP_DATA_IWLAN [START]
persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
2. Replace stock fulmics build.prop with the one from your carrier's rom with Fulmics part and above lines added. Check permissions and reboot.
3. Ho to hidden menu Field Test->GPRI VoLTE/VoWiFi->UX and tick all ON apart from 1, 2 and 7. Go back to main hidden menu screen and to to Service Menu->WoWiFi and change value to 1.
4 reboot and check if you have WiFi Calling QS Tile added and WiFi Calling settings enabled in call settings.

What apns do you currently have on the list?
Can you check what is your sim MCC-MNC CODE? Go to hidden menu, field test->SIM Info and check values under MCC and MNC. Is it 222 and 10??

Ok. I found apns for you. There are 3 more to add. Give me an hour or so and i will make apns-conf.xml for you. Make backup of your apn-conf.xml file and when i send you new one you will just replace your file with mine, go to settings wi
th apn list (one from screen above) and hit restore defaults .
One more thing... Can you tap on the top apn from the list to open it? Then scroll down to see apn type , take a screenshot and post it here

UK H850 - What's needed to make VoWifi / WiFi Calling work?

I've posted on a couple of other related threads about this but thought a fresh thread directly asking the question might help.
I have a UK G5 bought recently secondhand, it was on VM but is now unlocked and works fine on the Three SIM I've tested it on. It's been upgraded OTA by the previous owner to Oreo.
So, what's needed to make it work with WiFi calling on Three UK, or for that matter EE? I've tried the Oreo Three RoM & the Oreo Open EU RoM. I enabled WiFi calling via ADB, but no matter what I try, no menu appears giving the option to activate or use WiFi calling. There's also a setting in the 'Hidden Menu' to toggle WiFi calling but that made no difference either.
Both of the non-VM RoMs complain about being used on the wrong carrier's phone, I know that can be fixed by removing some files in root, but what this tells me is that there are files or settings on the phone that don't get erased with a factory reset. Is it possible to get these files or settings from a Three UK G5 and put them onto another G5?
I did read on another thread that someone had got an ex EE phone working with WiFi calling on a Three SIM, that was with a Nougat RoM. I'm not too sure about trying this as I've seen a couple of stories about bricking due to flashing a lower numbered Anti Rollback RoM.
Any thoughts welcome.
I've loaded a Three UK Nougat RoM and can see that all of the VoWiFi settings via ADB & the hidden menu are on but cannot see any VoWiFI menus. My phone is on Three UK, I'm not sure if there's a menu item for WiFi calling though..
I found a couple of pointers relating to OREO:
https://forum.xda-developers.com/showpost.php?p=78463793&postcount=136
And here, plus a few posts further down on the same page
https://forum.xda-developers.com/showpost.php?p=78584284&postcount=175
I've had some success in enabling WiFi calling on my G5 H850, after getting some ideas from reading these threads and thought I'd share some info, maybe there's a better way of doing this, if so, am happy to learn:
1, about the misc partition
https://forum.xda-developers.com/lg-g3/general/how-to-change-region-t2904951/page8
2, misc partition location on the G5
https://forum.xda-developers.com/lg-g5/help/little-help-misc-partition-h850-t3671068
My phone was originally sold by Virgin Media in the UK, my SIM contract is with Three.
I changed a couple of settings in the misc partition to make my phone think it was from Three.
I take no responsibility for anything that happens if anyone tries this themselves!
1, Unlock the bootloader to gain root access
https://forum.xda-developers.com/lg-g5/development/official-european-lg-g5-h850-bootloader-t3363040
2, Get a copy of the misc partition via DD (see first & second links above)
3, Make a copy of the copy, name one of them 'master' and put them in a safe place
4, Edit the second copy via a Hex Editor
At location 00014000 you will find the phone's MCC & MNC, I changed mine to 23420 (UK H3G)
At location 000D7000 you will find the Buyer Code, I changed mine to H3G_UK
5, Save the updated misc partition & copy it to the phone's internal storage. The thread that I linked at the top, shows the misc partition being saved to the 'sdcard' which on my phone turned out to be the internal storage.
6, Overwrite the phone's misc partition with the updated misc partition with DD.
7, Lock the bootloader
8, Using LGUP, flash the official Three UK OREO ROM to the phone
9, Start the phone, chances are it will not start properly due to some stuff left over from unlocking, if so you need to boot into recovery and reset to defaults
10, After going through the initial setup, check the dialler app settings and see if the WiFi calling option is there.
Does anyone know the correct NTCODE and BUYERCODE to brand an unbranded H850 to Vodafone Germany? I want to try the branded firmware because it supports VoLTE and VoWifi out of the box. I followed the instructions in the previous post but it does not work. The original NTCODE and BUYERCODE are "1","FFF,FFF,FFFFFFFF,FFFFFFFF,11" and OPEN_EU. I changed these to "1","262,02F,FFFFFFFF,FFFFFFFF,FF" and VDF_COM , flashed back the misc partition and after that I flashed the vodafone KDZ. Factory reset was also done but it still does not load the branding in the VDF_COM folder on the cust partition. The software version is reported as V30f_EUR_XX instead of V30f_VDF_COM. Is there something else I have to do? A Vodafone SIM card with MCC 262 and MNC 02 is inserted.

I changed these to "1","262,02F,FFFFFFFF,FFFFFFFF,FF" and VDF_COM , flashed back the misc partition and after that I flashed the vodafone KDZ. Factory reset was also done but it still does not load the branding in the VDF_COM folder on the cust partition. The software version is reported as V30f_EUR_XX instead of V30f_VDF_COM. Is there something else I have to do? A Vodafone SIM card with MCC 262 and MNC 02 is inserted.

I'm not sure why your patching did not work, but I have turned off WiFI calling on my G5 because the call quality over WiFi is terrible. It may be that I did not find all of the changes that are needed.

How to enable Volte

I see lots of discussion on rooting, unlocking bootloader, etc. But I am wondering if there is guide describing how to enable volte for tmobile? That is all I am looking for and I am really not savy/technical when it comes to phones. I have the dual SIM 850 emw and I really dont want to lose use of the phone when tmobile dumps 3g next month. Thank you
Found this. Sort of cryptic.
I used the dailer code on my Samsung to verify VoLTE was enabled, otherwise it doesn't show the setting or that it's even HD.
Apparently AT&T supports this device if your carrier drops the ball. Verify this though...

Thanks for pointing me in the right direction! I now have VoLTE and Wifi Calling working on my LMG820QM (on T-mobile).
I have the BPT variant of the LMG820QM, for which VoLTE and Wifi Calling does not work. After bootloader unlocking and rooting, I tried the above VolteFix-v1 but wanted Wifi Calling. Forcing the option to appear via a profile in Universal Enabler in the hidden menu* did not work and instead caused LG IMS to continuously crash.
*For those interested in the hidden menu, first create an empty folder named "enable_ue" in internal storage. Then go to the dialer and type *#546368#*820#. In Field Test > Universal Enabler you can "Create New Config" and manually enable VoLTE, ViLTE, VoWIFI, and ViWIFI. However, even though these options became enabled in *#*#4636#*#* they didn't seem to actually work.
Next, I tried to crossflash partitions from the US Open kdz but was unable to due to a size mismatch of the OP partition (among other problems).
Finally, since I had already extracted the OP partition from the US Open kdz (G820QM20f_00_NAO_US_OP_0402.kdz), I extracted files that looked relevant and copied them over using a root browser into /product/OP. After setting permissions and restarting, I now have working VoLTE and Wifi Calling!
The files are cust.prop [update: apparently not needed; my existing one worked just fine], all the files in config, and a few folders in priv-app [update: these are the apps for Wifi Calling!] not present in my phone's kdz (not sure which ones if any of these apks are actually needed but since it works I'm not going to experiment more). See attached for details.
Note: Since these files are from the US Open kdz, it will likely only work for US carriers. But the process can be repeated for other regions with the right kdz.
UPDATE: Replaced the attachment, had the wrong files in Config.
** Noticed that upon factory resetting the wrong default APNs are inserted. Had to factory reset on original files, have APNs setup correctly, then copy the attached files (did not copy over cust.prop this time and still worked).

Hello jdapp,
I was able to get VoLTE AND VoWIFI on Mint (T-mobile) with these instructions. I also posted what I did on Post 50. The files work for firmware 20 but if you need the ones for firmware 30 let me know.
Awesome thanks. Yes if I could get the firmware 30 files that would be great.

No problem, let me know how it goes.
So I have tried to do the bootloader unlock and flash but every time I get a Download fail: Sahara Fail: Q SaharaServer Fail: Process fail?
Any thoughts?
