XZP VoLTE firmware

[lancewicz]

Hi Guys,

I'm almost happy user of XPZ. I bought non-branded version G1842 dual. I want to use VoLTE(and WiFiCalling if possible) on my handset. My operator Orange PL supporting VoLTE but only on Iphones and branded firmwares for Android phones.
Sony support/service refuse to flash my phone with Orange firmware - so I would need to do this alone but official Orange firmware is available only for single sim XPZ G8141.
Question - can I seftly flash G8142 with G8141 firmware? Or do you know that maybe VoLTE operator configuration is kept in one of sin files like modem_X-FLASH-ALL-42E5.sin and I could just swap one file in whole firmware folder?

Secondly VoLTE - I send email to operator and they replay that configuration of VoLTE is many settings/parameters inside firmware. Besides *#*#4636#*#* option VoLTE provisioning I didn't see any configuration for this service. The config is so deeply inside firmware? When I switch ON this option in that menu it's not saved and when I enter once again the menu is one again switched off.
What I saw most of the VoLTE arround globe have problem - that they need to use branded firmware. Do you think in the future it would change? As far as I check for Iphone it works on all - it's relevant it's branded or non-branded phone.

best regards,

Piotr

I'm in Sweden and VoLTE got enabled for me when I switched carrier. I didn't do anything but switch SIM. I had a Z5 Premium at the time and now I'm on a XZ Premium and VoLTE is enabled as default.
And standard Nordic Combined firmware, no carrier lock.

Piotr, i think with DS version of device you are out of luck. There is no european provider specific modem configuration(required for volte) available for the dual sim device. I have attached available configurations in the zip file.
To get single sim modem configuration files flashed to device, you need to flash system.sin, but i STRONGLY DO NOT recommend doing that. Potential brick on your way.
Mixing flashing the single sim and dual sim different .sin files is highly experimental.

If you really want VoLTE then i think less headache is if you can find a person who is willing to switch single sim version with you.
You can get any region G8141 and then flash https://xpericheck.com/cda/1308-7002
Phone needs load configuration amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn to get VoLTE and VoWIFI.
Checking current oem.sin file, i can see that when inserting Orange PL sim, then amss_fsg_maple_orange_poland_ims_tar.mbn is actually loaded.

Is the XZ Premium on confirmed VoLTE devices list on Orange Poland webpage?

Hello, any news in this thread? I have the same situation but with XZ1. I have nonbranding dual sim working on T-Mobile PL. They sell XZ1 only single sim, so there is only single SIM firmware from T-Mobile. Someone test flashing single SIM firmware for dual SIM XZ/XZ1 Xperia?

 

[VeixES]

Should be same situation as with xz premium. flash single sim fw via newflasher and you are done. will lose 2nd sim but otherwise should be good.
Please Read different topics to know how other users have done it to xz premium dual sim.

Are dual sim variants of xz1 and xzp installed with the required 4x4mimo hardware antennas?

Just flashed XZ1 DUAL with XZ1 SINGLE firmware. Everything work at this time fine and VoLTE and VoWIFI are working from the start!

All functions with single sim firmware work properly?
Phone now reports as g8341 (singles sim) to the mobile carrier?
What does now show in the model number of your device menu?

I send you PM with screenshot. All functions work well from 8 hours. NFC, VoLTE, VoWIFI, caliing, messaging, LTE, 3G etc, no problem with anything at this moment.
In system information stay now G8341, and naturally i lost second SIM in menu.

Great! Dualism is sold cheaper than singlesim

Why dual sim are sold cheaper then singlesim? Which country?
I bought XZP in presale and price for non-brand and brand at telcos was the same. For me I was thinking it's benefit because I get dual sim and "clean" FW.
I suppose that Sony (and also Samsung) don't care about this....I hope that carrier services app in android recently added by Google would be the way to update settings for operators for all headsets. Like apple does. That would solve that configuration....
Only when small file missing and and lot of issues with VoLTE and VoWiFi.

Maybe single and dual sim are exactly the same HW? and when you load DS FW into SS version you will get DS? anyway 2sim share slot with SD ...maybe Sony simply manufacturing process?

To confirm files like amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn are kept in which file? oem_X-FLASH-ALL-42E5.sin or modem_X-FLASH-ALL-42E5.sin ?
This file are modem configuration so it should be more in modem.sin but you mention that you check oem.sin for that maple config?
Is 100% configuration of VoLTE are kept in amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn ?

In 20 minutes I would also try to flash XZP like rav.6 with XZ1 to check that solution. And let all know.

br,

Piotr

 

[VeixES]

oem.sin only includes instructions which configuration(.mbn) to load.
all configuration are universally available in system.sin

I can confirm. Solution by rav.6 is working also on XZP with Orange firmware Poland.
I see now options for VoLTE and VoWiFi and VoLTE are enable but not working
I don't know why

In T-Mobile I have activated VoLTE and VoWIFI by sending message to T-Mobile. I don't know how it looks in Orange, but i think you must activate it first.

So what is in modem_X-FLASH-ALL-42E5.sin ?

So what is in modem_X-FLASH-ALL-42E5.sin ?

Generic modem/radio needed files, which are needed for the modem to work. Identical in every region firmware.
