ppkg file

Hi,

Could you please share the ppkg file for the L640 T-mobile provisioning.

thanks
[Windows 10 Mobile] anubis23:
Hello there, I unfortunately do not have the spike file for the T-Mobile Lumia 640. As far as enabling*VoLTE*or WifiCalling on the Lumia 950DS, it*seems out of reach to use because I am at*the conclusion to enable this we have to find a way to flash the modem .nvi file. I tried to*flash the 640 LTE from mobile customer nvi*file, along with the ATT 950 nvi file for the DS version and no take. If you look at the nvi file, it*has all of the necessary information that needs to be applied to the modem for LTE and Wifi Calling to work with registry tweaks and so forth.
[Windows 10 Mobile] brownie80:
I successfully flashed the 950 XL Single SIM firmware of the German T-Mobile / Telekom onto my 950 XL Dual SIM un-branded phone - and now VoLTE works flawless. Of course I was losing the capabilities to use the 2nd SIM slot. It's just not recognized, or better: the 2nd call button and all the other settings doesn't show up.

Maybe someone can analyse the differences between both firmwares to find out what kind of settings needed?

The German T-Mobile / Telekom also supports WLAN-Call on iPhone and Galaxy S6/S7 phones - and as I understand its an IPSec connection to the network core of the provider - so at least settings like target IP / DNS, and maybe some certificates must be baked into the firmware somewhere, even if the SIM card itself does the encryption shake-hands with the network core.

Someone any idea? Maybe these connection setting can taken from the Android firmware somehow?

Product code

Can you provide us the product code which u have used? German T-Mobile 950& 950XL,???
[Windows 10 Mobile] brownie80:
sure, its 059X4V3 on a Lumia 950 XL - and can be flashed to an 950 XL Dual-SIM as well, with losing the DS capabilities.

VoLTE is available and works flawless even in latest Developer Preview.

WIFI-Call (or WLAN Call in Germany) would be nice to have as well.

The operator-name is TMO-DE.
[Windows 10 Mobile] honigbar:
Any way of getting ATT's VoLTE working on the DS 950?
[Windows 10 Mobile] brownie80:
I think the main problem are the correct NVI settings - beside some registry tweaking. We have take the correct settings from a working NVI configuration of a working FFU file and just update the NVI part of the phone.

Does anyone can extract these information from an FFU part?

Flashed the t-mobile ffu to my lumia 640 DS without a sim card in and Volte and wifi calling on t-mobile works on latest release preview windows 10 mobile. :D

Thanks brownie80! else i wouldn't even tried to flash a single sim ffu to my dual sim. Confirmed lost the use of second sim but I don't use it anyway....

Btw I flashed the tmobile ffu updated all apps then installed insider release preview then installed windows 10. Updated apps again and then update to 14393.448. For me, I had to install the tmobile app from store and open/login using data NOT wifi then wifi calling works. Have to make sure that ims registered.

Hey this is good news, I always wondered if this was possible and now that you have confirmed it, I can*now try different paths such as this to get the LTE working. Thank you for attempting this and posting.
[Windows 10 Mobile] brownie80:
THANKS! I already did some digging around in the mounted image, but any NVI settings in my Lumia 950 XL Telekom-branded ROM I did not found, which can help me to understand the settings needed for other phones. I guess, it must be in another partition or some bootloader to initalize the modem.

Any idea how to go deeper somehow?

Does VoLTE works in Nokia Lumia 735?

Hey everyone...I've a VoLTE supported sim...But I can only use Data and not calling and messaging..Even I can't receive call in my device with this VoLTE enabled sim...My friends are easily using these VoLTE service in their Android and iOS handsets but I can't do so..

I've Lumia 735 in region INDIA and VoLTE enabled sim is JIO and my device service provider - CV GBIE.

Please anybody help me to activate VoLTE calls in my Lumia

Hi. It might have been posted here already and I missed it. Has anyone tried what was posted earlier but for the 950 Dual Sim? Flash a RM-1105 ROM to a RM-1118 for use with AT&T (of course single sim will only be available) correct? Are there any known issues with that? Thank you.
[Windows 10 Mobile] nate0:
Has anyone tried looking for and/or pushing the cabs for the RM1105 ATT 950 in order to enable enhanced volte services on the DS 950?

Sent from mTalk
[Windows 10 Mobile] nate0:
Hi. I was able to do this on my unlocked dual sim US 950. In order to do it though I had to alter the platform ID via cabs from the att variant, and also I had to do a full nvi update reflash with the newest rm-1105 rom. The first go at it rendered both sim slots useless because I only flashed the rm-1105 ffu file. I thought I was out of luck until I re-issued the full nvi update flash manually. I think I also have to register the imei with ATT, but enhanced services is already available and the default apn is nxtgenphone. About to update to the newest production build soon and see how it goes...

Sent from mTalk
[Windows 10 Mobile] nate0:
There are thor2 options to send nvi messages to log but that is not capable to flash or update anything it seems. I never got anywhere with that. I honestly should have tried this below after updating the platform ID for my DS 950 to just flash the needed data, before flashing the whole ffu first.

Assuming your Lumia is able to flash the ffu with volte settings:

Maybe try thor2 -mode uefiflash -ffufile "RM-xxxx.ffu" -do_full_nvi_update -skip_flash

EDIT/UPDATE: I think there's more to it than that though, as updates are for the modem partitions which may already have the layout/structure from the volte enabled rom. I honestly did not want to spend days on this, and being on att I really just wanted the advance LTE services intended and new by example that a full flash of the intended rom was the easiest decision to attempt this.

Sent from mTalk
[Windows 10 Mobile] brownie80:
I would like to mix some options: the*VoLTE-enabled*ROM options from the Lumia 950 XL Single-SIM*and the Lumia 950 XL DS ROM option*to enable both SIM-cards. As another nice addition I would like to add Wifi-Calling as well, which*works perfectly on Android phones*branded from German Telekom, but they*are not updating firmware for the branded Lumia 950 XL Single-SIM anymore. So I would like to help my*Lumia*in combining all options, collected from other operators, or trying to extract these information from the Android phones and*apply them somehow.

As a second goal I want to achieve is the VoLTE support for my Lumia 1520, which*is not supported from German Telekom at all, but*basically its just a question of the correct NVI settings.

I am pretty sure it must*be possible to just flash the*NVI part with THOR2 - plus the correct registry settings, it should be*possible - as hardware, software and the network does*support it!
[Windows 10 Mobile] nate0:
I thought about that part with this 950 DS which had count-wise more FW updates than the ATT variant, but the ATT variant has a higher fw version...I am not certain how that equates to more options exactly on my side...

I agree. That the nvi updating was where I wanted to go from the start...

I see your goals here and sounds like a plan...I can tell you that what helped me as far as the cab-files goes, was the thread posted by TirstanLeBoss here.

---------- Post added at 05:35 PM ---------- Previous post was at 04:41 PM ----------

I can confirm now...Once, I registered my ATT lumia 950 imei with ATT under my account, the ims registration completed to one.att.net.
[Windows 10 Mobile] tearfalls:
Hello. Just wondering if your VoLTE trick also works with T-Mobile. And also do you get the WiFi Calling function to work? Last, the ATT branded 950 supports both PMA and QI wireless charging with no apparant hardware difference, I'm wondering if you flash your unbranded 950 with ATT ffu would it enable the PMA charging function as well?
[Windows 10 Mobile] nate0:
The lumia 950 is not yet supported by ATT for WiFi calling. For now it is a waiting game. If I moved this one to a t-mobile sim I do not see why not, as it has VoLTE/enhanced LTE services right now, I see if I can try it at some point. It is ATT that has limited the 950 amongst others from getting VoWiFi...I could test the PMA charging if you would like and let you know. How would I know the difference? I have used a Samsung wireless charger EP-PG920i for it before flashing the rm-1105 ffu, but I have an older Nokia wireless charger as well model DT-900 that I have not used.
[Windows 10 Mobile] tearfalls:
Thanks for your reply. In terms of testing the PMA charging, the simplest way I can think of is just to go to a Starbucks and try their wireless charging pad imbedded inside some of the tables. For some reason all the Starbucks use PMA instead of the more common QI standard. And just out of curiosity, how did you manage to successfully brand your unbranded 950 ds with the ATT ffu? I've tried to change my unbranded 950 ds' product code from 059X5G2 to 059X4D5 and use thor2 to flash the ATT ffu but it said unmatching code. Could you please share the your experience on how to do it correctly? Thanks again.
[Windows 10 Mobile] nate0:
I'll see if I can test the PMA this week. I can provide a short tutorial later tonight or tomorrow. As I know there could possibly be other avenues I could have tried or may have missed I wanted to possibly work with someone to run through it as I did. Then if needed improve what I did if possible in the event others want to use this knowledge too.

Sent from mTalk
[Windows 10 Mobile] tearfalls:
Much appreciated! A short tutorial would be very helpful. I'm about to manually update cabs from the ATT variant but now decide to wait for your tutorial just to be safe. Thanks.
[Windows 10 Mobile] nate0:
While yours is still on the dual sim rom, can you do me a favor and open field test. Check if band 17 and band 30 are there?

Sent from mTalk
[Windows 10 Mobile] tearfalls:
Sure. LTE Band 17 is there, but LTE Band 30 is not.
[Windows 10 Mobile] nate0:
Interesting. My field test shows band 30, but no band 17. Thanks for confirming this.

Sent from mTalk
[Windows 10 Mobile] tearfalls:
That's weird. You would think the ATT version would support band 17 since part of their LTE network depends on this band.
[Windows 10 Mobile] tejashash:
can this work on LUMIA 730 Dual Sim
[Windows 10 Mobile] tearfalls:
Just to report and sum up some of the tests I've done.

1. Flash the unbranded 950 to ATT 950 won't bring VoLTE function to carriers other than ATT. At least it won't enable VoLTE for US-Tmobile.

2. Flash the unbranded 950 to ATT 950 won't activate the PMA wireless charging function. ATT's version must have some hardware differences which are not visible.

3. Flash the unbranded 950 to TMO-GE version (T-Mobile Germany) also won't bring VoLTE function to US-Tmobile.

To sum up, so far still no idea how to enable carrier-specific function on an unbranded device if there is no carrier-specific ROM already available.
[Windows 10 Mobile] nate0:
Are there any T-Mobile Windows 10 devices that get wifi calling? I dont use t-mobile... As far as AT&T I own a Lumia 830 and now have my Lumia 950 DS with an AT&T ROM, and neither have ever supported wifi calling. Only enhanced LTE services.

Sent from mTalk
[Windows 10 Mobile] tearfalls:
Yes, every T-Mobile US branded Windows 10 device supports wifi calling. Such as Alcatel IDOL 4S. And many reported that T-Mobile branded Windows 8 device such as Lumia 640XL also has wifi calling after upgrading to Windows 10.
[Windows 10 Mobile] nate0:
How about hd voice?

Is the quality any better than AT&T? If it is I might have to consider switching...

Sent from mTalk
[Windows 10 Mobile] tearfalls:
HD VOICE/VOLTE is available for any T-Mobile branded Windows Phones. Unfortunately I was not able to enable it on my unbranded 950 so I don't get a chance to experience it. But the regular voice is good enough so it does not negatively affect anything.

I used to have Verizon on Lumia Icon. All the IMS function works well. Switched to T-Mobile so I can use newer devices without having Verizon's "approval". So far so good about the service. I went to Europe this year and tried their free data/message roaming. It worked great. In some countries you even get 4G or LTE service with speed over 10mb/s.
[Windows 10 Mobile] nate0:
If using an unlocked Windows device on ATT, the voice/call quality is horrible. Almost every time I answered a call I would hear a screech followed by the persons voice for about the first 10 seconds then it would disappear. So glad that is over with the ATT rom.
[Windows 10 Mobile] agriz:
How did you get access to registry? I want to enable volte in 650
[Windows 10 Mobile] nate0:
There is a really nice tool called Interop Tools. Search the forums and follow the directions provided with it if you want access. Let us know if you enable it...
[Windows 10 Mobile] agriz:
Sir, after installing interop tool, can I get updates from windows?
[Windows 10 Mobile] nate0:
There's nothing stating the opposite. The program itself is not known to prevent updates. However what you do with it could, I suppose. Please see the developer's thread on the tool and ask there for more info.
[Windows 10 Mobile] sco1984:
Tried.

Not working in my Lumia 830. :(
[Windows 10 Mobile] sco1984:
I tried this in my Lumia 830 today.

I performed following steps

i) Installed 'Interop Tools' in my Lumia 830 having latest Windows 10 Windows Insider preview version i.e. 1704 (10.0.15047.0) build

ii) Edited = HKey Local Machine\SOFTWARE\Microsoft\Phone\Settings\PartnerImmediateDialStrings

iii) Put ##3282# at very beginning of the line

iv) Restarted phone but Nokia logo kept flashing for a while. Removed battery, reinserted & started phone & it booted properly

v) Now dialed ##3282#

vi) Got following screens & options.

Not sure which will help.

I am using Reliance Jio 4G sim in this Lumia 830

Rumours says Reliance Jio is using different band of 4G which is making difficult to enable phone for voLTE calling.

How ever I am not sure if it's because I have not used voice calling in my phone yet.

Will update shortly after I put Jio 4G sim in LTE based Android phone & activate voice calling.

Regards,

Amey.

[Windows 10 Mobile] nate0:
I found a way to enable AT&T VoLTE services/IMS registration on non AT&T Windows 10 mobile phones including a Lumia 950 XL (still testing the XL). So far I have had it work on the Alcatel IDOL 4s. I wanted to share it here since there were two carriers mentioned AT&T and T-Mobile. So if my method works for AT&T then it might be worth it to check out a T-Mobile certified Lumia phone or ROM for the same solution.

You will need an interop unlocked phone, full filesystem access via MTP or SFTP and some files used for provisioning the modem and other settings on the phone.

The trick is to get access to the C:\PROGRAMS folder on the phone you need changes done. Once you have read/write access there it is pretty simple after that. Mind you that this only worked for AT&T thus far.

Under C:\PROGRAMS\COMMONFILES from a phone/ffu working with VoLTE on the carrier, there are more than several directories there that act as the provisioning for this. What I have been doing is copying over everything under C:\PROGRAMS\COMMONFILES\ADC C:\PROGRAMS\COMMONFILES\OEM\MMO C:\PROGRAMS\COMMONFILES\RCS. I used the files from a Lumia 950 RM-1105 for the IDOL 4s to work.

Copy the files from above and replace the ones on the other phone your working with.

Once I did that, I noticed that after several hours my phone provisioned keys and setting on it's own and showed the Toggle for Enhanced LTE services. From there I did a hard reset just to see the results, and it again provisioned the settings, keys all on its own. From that point I had to register a Lumia IMEI that is certified for VoLTE on AT&T. But once that was done it worked. I do not think it is perfect as their might be drivers that are used for the HD voice and such, but it works. I get LTE while on phone calls and not 4G. I also get the keys added for all the ims settings automatically. The APN defaults to nxtgenphone on its own too.

UPDATE: This definitely works with AT&T. Since I was almost blindly doing this about a week ago, I have since flashed over twice now my IDOL4s (w/ the T-Mobile FFU) and realized I only have to add and replace the files and folders under C:\PROGRAMS\Commonfiles\ADC with those found in a 950 AT&T FFU. Once done I simply do a hard reset with the sim card inserted. Once up and running the VoLTE toggle for IMS is available, but I have to ask ATT to update my IMEI. After that and a couple reboots and HD voice is enabled.
[Windows 10 Mobile] tearfalls:
Hi nate0,

Good to see you still working on it and thanks do much for sharing this tutorial. For us T-Mobile users, is it possible for you to extract and share the provision file from the idol 4s T-Mobile firmware?
[Windows 10 Mobile] nate0:
I'll take a look, but I am not certain if T-Mobile uses the same method or not for their services. I suspected they did.
[Windows 10 Mobile] tearfalls:
Thanks a lot. It will be great if it works with tmobile as well. WiFi calling can be really useful.
[Windows 10 Mobile] nate0:
Looks like the only provisioning is in the ADC folder. You can browse through the cabs and see the ims settings there. I could not find any other files from my perspective. Give these a try I suppose.

Edit: I used Windows Phone Internals to dump the main OS, then mounted it with OSF mount. So if you want to look more at that FFU, you can use that way.
[Windows 10 Mobile] tearfalls:
Thanks for the file. However, I overwrite the original files in the adc folder but it seems to be not working. Guess there is some other provision files or rather the idol 4s uses a different structure than Lumia.
[Windows 10 Mobile] nate0:
I have full access (r/w) on the 950xl using sftp, but only on earlier OS versions. If I take an update I still have access but cannot write the files. 15086 version of W10M seems to allow the access for me on the XL.
[Windows 10 Mobile] poken1151:
Has anyone else verified this? Seems like a possible no-wipe solution (well, assuming I can interop-uinlock on the latest preview with no wipe.... can I?).
[Windows 10 Mobile] tearfalls:
I'm on the latest Feature 2 branch and I can use putty to copy and overwrite files under ADC folder but it does not seem to have any effects other than reset my calling history/voice mail box content.
[Windows 10 Mobile] nate0:
I have IMS registering on the 950xl DS I have, but at the moment am having issues with the modem defaulting to 4g only. It will regiser and be good there but I lose all the LTE bands being enabled by default. I am not certain if it is due to the dual sim config/setup or something else out of order I did.
[Windows 10 Mobile] tearfalls:
Perhaps it will be easier to use a tmobile Lumia 640 as a reference model. I'll look into it more tomorrow. Thanks for all the help again.
[Windows 10 Mobile] nate0:
There are also some ELf files under c:\windows\system32 that I never noticed on other phones. Maybe someone can decipher what they might do or if they are useful. There might be some settings in there that are used during that time. They are under c:\Windows\System32\mcfg_sw c:\Windows\System32\mcfg_hw. The list here are from the IDOL4s T-Mobile FFU
[Windows 10 Mobile] tearfalls:
So, I was able to make WIFI Calling option show up in the menu. However, the IMS is still showing not registered and neither WIFI Calling nor VOLTE is working depite that the option shows up in the menu. Not sure what can be done next.
[Windows 10 Mobile] nate0:
Well the 950 is not whitelisted on T-Mo. So go from there I assume, right?

For ATT I have to have them update a Windows Lumia 950 IMEI that is whitelisted for VoLTE on their network.
[Windows 10 Mobile] tearfalls:
If that is the case, I guess that is as far as we can go. Just tried again to use ADC folder from Tmobile Lumia 640 to replace my 950's ADC folder. The Cellular menu looks a bit different with WIFI calling option there as well but still won't work.
[Windows 10 Mobile] nate0:
Why is that?
[Windows 10 Mobile] nate0:
Those files I gave you are from the T-Mobile IDOL4s variant that has VoLTE and wifi calling. Maybe find a demo model (if one is left) see if you can get them to try the imei. Not sure what else to say.
[Windows 10 Mobile] tearfalls:
Hey nate0,

After further digging through the system files, I found out that a lot of the provision settings seem to depend on a file located at: C:\PROGRAMS\CommonFiles\OEM\Public\MMO\Multivariant\modemconfiguration.cab

Could you please do me one more favour and share this cab file from the IDOL 4S TMO ffu? Or better if it is possible, share the complete ffu with me? Thank you very much.
[Windows 10 Mobile] nate0:
Ok. Yes I have that file. Sharing the complete ffu is out of my capacity at the moment. I will PM you later tonight. I am at work atm. I believe you still will need to get it provisioned on T-Mobiles end too though. So you want the whole FFU? Just got to WDRT, select Alcatel. Then IDOL 4s. Then the T-Mobile model. Hit the button and download it.
[Windows 10 Mobile] nate0:
[MENTION=7959283]tearfalls[/MENTION]

I was mistaken. The modemconfiguration.cab is on the Lumia's. For the IDOL4s it was not there. So, as far as the modem nvi being updated, I am not certain how T-Mobile handles it.
[Windows 10 Mobile] tearfalls:
Hello nate0,

Yes I downloaded the IDOL4 ffu and found out that there is no modemconfiguration.cab. But thanks for checking it for me.
[Windows 10 Mobile] poken1151:
Hi, I'm butting in a bit fully green. Just got interop tools installed, how did you get the option to at least show up in the menu?
