[GUIDE][WIFICalling][VoLTE][T-Mobile.pl] Getting VoWiFi/VoLTE working in Poland

[Menteslili]

OK, so I downloaded the FW with XperiFirm, extracted it with FlashTool and mounted the system.ext4 to get the modem config "amss_fsg_kagura_telekom_germany_volte_vowifi_tar.mbn". I stripped the 552 bytes header and extraced the tar file.

But now I'm hanging at the next step. The nvpreload folder includes 3 files, but these are no tar files, just compressed data.

Could you describe the next steps a bit more in detail? Right now, if I just uncompress the largest file, place the nvitems_list.csv in the root folder of the extracted modem config and run the jar file, I get the following error:

[email protected]:/tmp/modem$ java -jar cnvparse.jar 
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
	at ua.org.solk.qc.CNVParse.main(CNVParse.java:37)

At the end, VoLTE and VoWifi should work for both SIM slots as both have a T-Mobile SIM card (private and business). Does this work like this?

Thanks for your help,
meiser

Hallo Meiser kannst du mir Helfen ich finde diese Datei nicht, wie gesagt System.ext4 gemountet aber diese datei ist erhalten..""amss_fsg_kagura_telekom_germany_volte_vowifi_tar. mbn"

Why do you need this for TMO US. There is signed mcfg_sw by oneplus /etc/firmware/mbn_ota/mcfg_sw/mcfg_sw_TMO-Commercial.mbn. If its not picked up automatically then just load it and active it in QPST.

How can you load that?


I've tried this mod, but my phone is not even initiatinfg the IMS bearer.

The data profile folders are completely missing for my carrier.

Shouldn't it be possible to replace the stock mbn file on the OnePlus with for example the Sony one?

Is there a way to activate it from COSMOTE in Greece? They support some devices, but not op3. They support phones you can buy from them and only after you flash their specific firmware.

@jamal2367 and @solk2 Can you please assist me with setting this up for providers in the NL. i would like to get started.
Update:
Its working, big thanks to @jamal2367

Hi Jamal,
could you please make it on T-Mobile CZ (Czech Republic), please?

Hi Jamal,

Just tried your Telekom DE file but seems like LOS/AOSP based firmware is no good idea, huh? Still a call causes fallback to anything below LTE, settings for volte/vowifi are active though. One question regarding item file overwrite. When I throw (aka, right click item file import) the files in the correcponding folders they are found inside twice until a refresh, I think this is OK?

Can someone make it also for Vodafone NL?

 

[Darkje]

@puschkin sorry i dont think we can. We cannot pull it from a device. @solk2 and @jamal2367 OR could we pull it from a Nokia perhaps..

It may be next to impossible, but if this can be adapted for Claro Argentina it would be highly appreciated. For Android they have both devices with built in support (sold by them) and through an app (https://play.google.com/store/apps/details?id=ar.com.claro.vowifiacs). For iOS it's built in. TIA

If the Sony phone is There IT should be possible. You van follow the guide by extracting the mdn.

Eir network in Ireland supports WiFi calling, but only on limited phones purchased from Eir and with some postpaid sim plans. I don't know how possible it is to make it work on oneplus 3t and with a prepaid sim plan.

I managed to download G8341_Claro AR_1310-8711_47.1.A.12.179_R11B (Xperia XZ1) with XperiFirm, extract system_X-FLASH-ALL-C93B.sin with unSIN, but I'm not seeing a system folder when I mount the ext4 image. Only a [SYS] folder with a Journal file in it. Any ideas?
