I have a Xperia Z5 UK model E6653. But it does not have Volte enabled? Any idea on how to enable it?
I have tried the following:
1. Tried installing EE firmware to check if VoLTE is getting enabled
2. Ran the code *#*#4636#*#* and check for VoLTE provisioning flag. The flag is present but I am unable to toggle it. It displays Turn Off VoLTE provisioning flag.
Any help would be appreciated. Please note that I am currently with Virgin 4G plan.

The patch has not been tested in the call to HD since my carrier does not support VoLTE.
The patch activates flags VoLTE.
And yet, you need to find the settings of the access point to the IMS operator, and enter them in the APN.
Install the patch via twrp recovery.
Firmware 32.3.A.0.376.

Thank you for the test, I will continue to test.
You can try to change the modem in accordance with its operator.
For this you need to modify the line ro.build.type=user to ro.build.type=userdebug in /system/build.prop and reboot the device.
Then you need to install QuickShortcutMaker and click on the Customization Selector and make a shortcut for the Modem Switcher.
After opening the Modem Switcher, select the modem in accordance with its operator.
And most importantly, you need the original keys TA (maybe). Them in - you can invest using the Trim Area Of Proof Of Concept. Continue to test.
Beta 2.3 will activate VoLTE and Wi-Fi Calling.

You can try to install the patch for the firmware 32.2.A.5.11, but I can't guarantee stable work.
You need to change the modem in accordance with its operator, and add the profile to the IMS APN.
Then you need to install QuickShortcutMaker and click on the Customization Selector and make a shortcut for the Modem Switcher. After opening the Modem Switcher, select the modem in accordance with its operator.
Who installed these patches, please write if it works with your carrier.
A few days ago, wanted to test the patch, but failed. Operator is not connected IMS me as the phone has not been tested on their support for VoLTE.
After installation, you need to choose a modem in accordance with its operator.
You need to install QuickShortcutMaker, then open it to make a shortcut using the app then go to Customisation Selector \ Modem Switcher. Open Modem Switcher and select modem according to your network operator. If the selection of the modem's cellular network is not, then restart the phone.
You also need to restore the access point default to the new profile activated! ( Settings>More>Mobile network>APN>Reset to default )
If VoLTE does not work and You know that your operator you hooked VoLTE, then you need to change the APN in the profile apns-conf.xml (patch_ims_for_xperia_z5_beta_Nougat_Roms.zip\oem\android-config\apns-conf.xml). You need to find the profile of the IMS of the operator and to add to the "type" parameter "xcap". You should get something like this:
Code:
<apn carrier="Test IMS"
mcc="001"
mnc="01"
apn="ims"
type="ims,xcap"
protocol="IPV4V6"
roaming_protocol="IPV4V6"
/>
And most importantly, you need the original keys TA.
IMS description
RCS description
If VoLTE doesn't work, you will have to edit the "nv item" or "amss_fsg_***.mbn" (\system\etc\customization\modem\).
Maintain feedback to know if the patch is working.

Hi @grayleshy,
I would like to ask this patch will work with all bands and all operators?
My operator Turkcell in Turkey, it supports VoLTE&VoWifi but not Z5.
Only:
- iPhone 6, 6 Plus, 6S, 6S Plus, 7, 7 Plus, SE
- Samsung S6, S6 Edge, S7, S7 Edge
- LG K10 (2017 model), G4, G5, V20
If not work, how can we add this for Turkey operators (Turkcell, Vodafone, Turk Telekom)?

For start on these operators it is necessary to make the following:
1. It is necessary to edit an APN profile (patch_ims_for_xperia_z5_beta_Nougat_Roms.zip\oem\ android-config\apns-conf.xml ; patch_ims_for_xperia_z5_beta_Nougat_Roms.zip\data\customization\ota-config\apns-conf.xml)
Find mcc="286" and change the profile Turkcell IMS at:
Code:
<apn carrier="Turkcell IMS"
mcc="286"
mnc="01"
apn="ims"
type="ims,xcap"
protocol="IPV4V6"
/>
Add:
Code:
<apn carrier="Vodafone IMS"
mcc="286"
mnc="02"
apn="ims"
type="ims,xcap"
protocol="IPV4V6"
/>
<apn carrier="AVEA IMS"
mcc="286"
mnc="03"
apn="ims"
type="ims,xcap"
protocol="IPV4V6"
/>
XCAP - The software of the smartphone sees access point of ims and requests a configuration according to the xcap protocol. In reply, from server side, xhml the response which loads in a software arrives and makes authorization on the ims domain with the subsequent activation of a functionality on the device.After a flashing of the changed apn, it is necessary to make so: Settings>More>Mobile network>APN>Reset to default.
2. If the operator does not support protocol xcap, you will have to edit the "nv item" (easier) or configurators amss_fsg_***.mbn.
Hi @grayleshy
Thanks for your reply.
I tried XCAP for 2 zips, but not work. I tried to change amss_fsg_***.mbn, not for Turkcell. I don't know what "nv item" is. Found this thread, but don't know what should I do with this.
Hi I own a pixel 2 xl. I live in Austria. My provider startet the volte support, but just for some samsung mobiles. I read that just phones worked who are bought directly from the provider with a branding. I talked with the support and the activated the volte for my telephone number. But when I look into the hidden menu *# *#4636# *# * then the volte is grayed out. It´s not possible to switch the settings on. A reboot of the phone doesn´t help.
I read in an German forum that someone changed the ims file from a unsupported samsung phone and activate the volte at the unsupported phone.
Where is this ims file located in android p? I know root is necessary to access this config files. Or is there an other workaround the activate the volte on pixel? (I read that for the one plus mobiles exists a workaround with the oxygenos)

Hello, I've owned a LG G7 G710ULM (US Unlocked) , and cross flashed to G710EM (EU Firmware)
Trying to modify this phone's modem to support carrier aggregation
Here's what I've modified:
/nv/item_ files/rfnv/00028874
added Taiwan operators ca combos
/policyman/carrier_policy.xml
added Taiwan ca combos strings
btw, found something strange
These values in /oem/OP/OPEN_EU/cust.prop
Code:
ro.vendor.lge.build.target_region=EU
ro.vendor.lge.build.target_operator=OPEN
ro.vendor.lge.build.target_country=EU
if I change these to:
Code:
ro.vendor.lge.build.target_region=ESA
ro.vendor.lge.build.target_operator=OPEN
ro.vendor.lge.build.target_country=TW
I can lock bands to 07 08, but can't do with original values
and QPST EFS Explorer Banner would be "DCM_Row"
So I tried to modified to OPEN/KR
Code:
ro.vendor.lge.build.target_region=KR
ro.vendor.lge.build.target_operator=KT
ro.vendor.lge.build.target_country=KR
QPST EFS Explorer Banner changed to "ROW"
It's so weired
Modified 28874, carrier_policy.xml, cust.prop and rebooted but still can't get carrier aggregation
Don't know how to insert uploaded images to thread, and sorry for my bad English
Hope someone would join this and discuss
Hey, interesting post. I have the same phone (LG G7 ULM) and I'm also interested in modifying CA combos but for LATAM.
Did you have to root to do all of this?
The firmware does not contain carrier files for China and Korea carriers.
I made a magisk module that installs these carrier files systemlessly.
I don't live in China or Korea so I have no way to test this.
If you're living in China or Korea, please help me test the module to see if it works.
Thanks.
Hi swangjang, thank you for sharing your module! I used QPST to replace the modified xml files to enable 5G, and now I installed your module. The 5G runs well, but I can't tell if it is enabled by your module.
For VoLTE, the switcher appeared in the option, but it dosen't work. When I made a phone call, the network drop to 3G. (My carrier is China unicom)

Thank you for testing.
I think due to dm-verity, the module files don't actually get placed in the system. I'll need to wait until we get TWRP to disable verity.
Can you try and change sim cards to force the phone to reload the mbn file?

Tbh, I don't think it will work.
I plan to install a custom rom (custom roms don't have dm-verity) in the weekend and see if the module works on there. As long as dm-verity is enabled, I don't think any /system modifcation by magisk will work.

Hi, I live in south korea and I have UK version of Pixel 5(GTT9Q).
I'll try this module tonight and see if it works.
May I ask you where did you get mbn files for korean carrier? In my experience, KT and LGU need some efs modification especially for google pixel series, so directly injecting mbn from other device won't work well.

I got the mbn files from Xiaomi Redmi K30. The K30 uses the same chipset as Pixel 5.
Just tested module in south korea, but it doesn't works.
It seems that magisk module is doing it's job. I run root explorer and confirmed that mbm_sw.txt and other additonal korea and china mbn successfully loaded.
But when I run efs explorer, Banner shows "SW_DEFAULT" instead of "LGU".
Maybe Pixel 5 can't load LGU mbn because of some other reason.

Thank you for testing. Did you install the A or B? could you try the other one as well to see if it works? Please make sure to uninstall first.
Also maybe take out sim card and insert again?

I read on a Korean forum that you may need to visit your carrier customer centre to register your device
???ۺ????丮 [??????, ???÷???, ????? ?ؿ??? Ŀ?´?Ƽ] : ???̹? ī??
cafe.naver.com
Under section 3. part (4), "VoLTE calls can be made only by registering OMD (Open Model Device) as a VoLTE capable model name with each mobile operator".
Also, after installing the module, maybe reboot the device once?

Hi, I changed the SIM card of another carrier but the 5G is still enabled, even after I installed magisk completely and restore the original files with QPST, the 5G is still there...
I doubt that the new firewares (Feb and Mar updates) canceled the carrier limitation for 5G.

Hi, I made more variations of the module using different mbn files for Korean carriers. Could you please them one at a time. It would be greatly appreciated.
I tried this with korean LGU, SKT simcard, but efs explorer shows SW_DEFAULT or Wildcard banner randomly.
I did sim tray out and in several times, and did WI-FI, Mobile Bluetooth reset on android settings-system menu.
And I also tried Taiwanese Chunghwa Telecom sim card which i got during taiwan travel, (Chunghwa Telecom is one of supported carrier for pixel 5) And It reports CHT banner correctly.
I don't know why, but it seems that pixel 5 refuses to load korean mbns for some reason.

Yes, I tried all of 6 mbns, but no luck. All recognized as SW_DEFAULT or Wildcard banner.
I'm trying to figure out why only pixel rejects those mbns. Maybe there's some hidden policy to reject unsupported country's sim?

I don't think there would be something that will reject it. Other people reported they got VoLTE working for their 'unofficial' carrier.
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
