Piggybacking VoLTE and Wifi calling from XZ1 Compact USA firmware? - Xperia Z5 Compact Q&A, Help & Troubleshooting

I have T-Mobile in the US, and they recently got rid of one of the bands my phone was relying heavily on, so I want to be able to do calls over wi-fi and VoLTE which is not currently a feature with the international firmware I have. Since the Z5 Compact hardware technically has the capability to do this with other carriers using the EE firmware, and the XZ1 Compact is specifically able to do this with T-Mobile with the US firmware, is there a way to either flash just the bits I need or root and install the whole XZ1 Compact ROM on my Z5 Compact?
Sorry if this is a dumb question, I've been reading about how folks buying the XZ1 Compact are flashing bits and pieces to get wi-fi calling and VoLTE working with the fingerprint reader (normally disabled in the US version), and thought if there's a trick I can do with my existing phone it might save me $500.

Z5 Compact stock rom already have VoLTE and VoWiFi function, but the option only appear if the network supports it, but probably not on the us firmware?

I have Hong Kong firmware that came with the phone. T-Mobile doesn't support the phone here in the US, but I did notice that there are firmware versions (Czech, Austrian, a couple others) that are T-Mobile branded. Is it worth a try to flash one of those (assuming it does include VoLTE), or for this purpose, would T-Mobile in another country be considered another carrier?
T-Mobile here in the US seems to be heading toward 100% VoLTE with only one 2G band left in my area. However, at least in the US, T-Mobile has not certified the Z5 Compact for VoLTE. I think the only Sony phone they've certified is the new XZ1 Compact. Does that mean I'm out of luck, or is there some kind of work-around?

I also have this issue, but I'm more of a noob to this than most people here, including the OP. I have a few fundamental (probably stupid) questions:

1.) How do you know this? How do you track what band(s) your phone is using?

2.) How can I check exactly what firmware I have? I got an international version when I ordered it from Amazon, so I didn't even have to flash anything to enable the fingerprint sensor. I also know it was from a Spanish country because everything was in Spanish when I booted it for the first time. But how do I know verify which version it is exactly?
Also, OP, did you ever resolve this?

I don't use forums too much, so I have a feeling I'm going to be commenting here within the quote. Sorry about that. I hope this is helpful.

I called T-mobile, and this is what they told me. In fact, it was so bad for their customers in my area that they were offering a special deal on new phones just to people in my service area.
How do you track what band(s) your phone is using?
I can't remember the code I used, but google "hidden codes xz1 compact" and you'll find a service code to see the settings. Be careful not to use one that will reset the phone.
1.a.) Again, how do you know that there's only that one band left?
Both through speaking with their tech support and reading their press releases online.

This is going to be in one of those service codes.

I ended up buying an XZ1 Compact and flashed the firmware for the international version with one portion using the US firmware. What I originally wanted to do couldn't be done with the old phone.
I made myself a file of notes back the first time I was taking care of all of this. These are not my words, but direct quotes from various forums, but I didn't keep all the sources so I'm afraid I'm unable to cite them properly. However, before embarking on this process, I should tell you that I haven't had any push updates since I did this over a year ago, and I haven't figured out how to repeat the process to update with new firmware. Good luck!
You can probably try googling some phrases from these in quotes to find the original sources:
I tried just those two files and didn't have any luck.
ETA - man, am I dumb! I accidentally was flashing the system_X-FLASH-ALL-C93B.sin and vendor_X-FLASH-ALL-C93B.sin files from the US firmware instead of the CE firmware! Once I used the correct files, it worked perfectly.
So to summarize (and definitely do at your own risk!)
0) I backed everything up.
1) I didn't load drivers because I had them.
2) I followed the directions at the link below to get xperifirm and newflasher, then used xperifirm to download the Xperia XZ1 poplar roms for G8432 Central Europe 1
3) I copied the two files listed above to my newflasher directory.
4) I shut down the phone, waited 5 seconds, then held down the volume down key and plugged it into my PC using a USB A to C cord.
5) I ran newflasher as administrator, and chose N when it asked if I wanted to load a driver
6) When newflasher told me I was done, I unplugged the phone and started it up.
The fingerprint scanner works, group texting works, and my system is showing the same signal strength!
See my screens in the prior 2 posts. It's really much easier than what you are describing. Download the Customized UK firmware from Xperifirm. Download the Customized US firmware from Xperifirm. Copy the system sin file and vendor sin file from UK firmware and replace the files in US firmware with the copied files. Flash the modified US firmware using newflasher tool. Bingo!
So I decided to take the plunge on this with the XZ1 Compact at least. Not only do I have the fingerprint sensor working, but also WiFi Calling and VoLTE on T-Mobile US.
I took the oem_X-FLASH-ALL-C93B.sin from the US Customized version, and overwrote the one included with the UK (Device is UK Model) version, and then proceeded to flash with Newflasher.
Everything seems to be working without issue. I couldn't possibly enjoy this phone more now.
I am being a bit lazy and will refer you to XZ1 Compact thread. pbarrette has done amazing job with figuring out all the bits and writing out how stuff works
Start reading from this post https://forum.xda-developers.com/sho...9&postcount=35
Most informative post is here https://forum.xda-developers.com/sho...&postcount=105
In summary, oem.sin from XZ1 Compact "Customized US" should be used to flash XZ1. All other *.sin etc files should be from XZ1 firmware (can use other region for fingerprint reader support).
Create folder caled 'partition', extract partition.zip into that folder and it will get flashed.
To put the phone in flash mode, you need to:
1] Power the phone off.
2] Press and hold the Volume Down Button.
3] While doing #2, plug the phone into your computer.
Device Manager should show an Unknown or Other device. Quite possibly the one above what you think is the right one.
It will have a device descriptor like this USB\VID_0FCE&PID_B00B in the "Details" tab.
Run newflasher and answer Y to the GordonGate driver.
It will exit after having dumped a zip file into the newflasher directory.
Unzip and install that driver for the device described above.
---
I know userdata.sin and fota-reset.ta is responsible for wiping userdata so its safe to delete these two files in case you need to keep userdata, but cust-reset.ta and master-reset.ta somebody need to try and let us know if these two files is also responsible for wiping userdata. The rest of ta files is ALWAYS recommended for flashing, don't skip it! Simlock.ta is by default skipped so you no need to delete it.

https://forum.xda-developers.com/xperia-xz1/help/flashing-international-firmware-model-t3683552
maybe best description

A quick update since my last reply:
I mentioned not being able to repeat the process. Turns out, it's because I didn't have the driver installed, which is basically step one. So user error, not related to any risk or issue with having flashed the custom rom to the phone.

[Q] Possible to change Lumia 800 firmware to another region?

Hi guyz,
I have a Nokia Lumia 800 with me of UK region and I dont mean just software wise. The actual phone was shipped from UK and the product code is 059J3G0
Now I reside in India and due to this region differences many of the features dont work especially USSD which is proving problematic since its difficult to even check my balance.
So is it possible to change my firmware to Indian version?
Thanks.
Possible very much, infact I have updated to the latest UK firmware, but will flash it back to the original White Lumia 800 firmware

Yes you can
1) goto seidea[dot]com and start off by downloading the Nokia Care Suit and Data Package Manager.
2) After installation of both also install the WinUSB driver from C:\Program Files\Nokia\Nokia Care Suite\Drivers or C:\Program Files(x86)\Nokia\Nokia Care Suite\Drivers
3) Connect your phone with the Nokia Support Tool for Store open, this programme will have a launcher in the main Nokia Care Suite, and should have detected your phone, disconnect cable, this might restart your phone, this is normal.
4) Next fire up the Data Package Manager and search for RM-801 in product type, this will return a bunch of different variations of the firmware. In the cell below Name type India and download any of the firmwares you want, possibly to match the colour of your phone as well.
5) After download fire up the Nokia Support Tool for Store, change it to offline mode at bottom right, or simply disconnect from the Internet,from the file menu, select Open Product and select product RM-801
6) From the bottom left pane, select Programming and then Recovery and select the new firmware you just finished downloading.
7) Flashing should take 5-7 minutes and leave the phone un-attended. Voila
Again I take no responsibility for any dammage to your phone, and you may download and flash any firmware from the entire list under RM-801 should not be a problem.
Additionally you may also want to take a backup from WP7 Easy Backup, google it or search the forums for it.
regards
Prateek
mohib.sheth,
no problems at all, i´m from Brazil and i updated to test Tango one from Mexico and another from UK, both worked like a charm.
U can follow this thread if u have any issues, like dead phone, errors or different Product Code
RM-819 Firmware on RM-801 thanks to thesmartguyy
or simple follow the original one Tango:
New update !! Rm801_059q201_1750.0805.8773.12220_002 thanks to surya467
Thank you so much lohiaprateek and xpc21 for the steps.
Another query is If I do flash to India firmware, will I get update from regular Zune or I will need to keep flashing to the latest firmware manually?
Zune should prompt the update ideally..

USSD is not supported (fully) in Windows Phone so as far as that goes changing to an Indian FW will not make any difference.

[Q] Using Motorola XT605 without sim

Hello, everybody. First, I am posting in this subforum because my particular device doesn't have a subforum. Feel free to move this thread if it may belong to a more appropiate subforum.
I'm going to describe the device briefly, since I think it's not very known outside my country (Chile). The XT605 (Known internally as Motorola Jorian, and as Motorola Master by my network operator [Nextel Chile]) is a GSM/UMTS device, with PTT functionality (it has a dedicated button for it). It runs Gingerbread, and there are not even official ROMs for it (Motorola's webpage doesn't have it). It has QWERTY keyboard. It seems to be the GSM version of Motorola Admiral (which is CDMA, sold in United States by Sprint/Nextel, I think).
Now, my problem is that I can't use the phone without a SIM. I've tried editing build.prop, starting with camera button pressed, and trying to use "Boot Android (No BP)" (the option doesn't even exist in the Fastboot menu). It keeps stuck in "Emergency Calls only" "No SIM". The phone works well when using SIM.
Also, if I put another operator SIM, the phone asks to delete all private data before allowing me to use the phone. I don't know to which data exactly refers to, so I haven't proceeded with it.
Thank you in advance, and sorry if I made some grammar mistakes.
Nothing?
Bump. Same phone, same country, wondering how to root it. Glup.
I no longer use the XT605, but Motofail can be used to root it.

Hi Buddy,
Maybe it is a little bit late, but doing a quick research I found out this http://www.taringa.net/posts/celulares/16686324/Firmware-Motorola-Master-XT605.html
It is the official firmware for the Motorola XT605 Nextel Mexico, yet it might work with your carrier, it basically is the same.
This saved my phone from being a brick.
Now, my problem is that I can't use the phone without a SIM.

I dont't know why, this happens but this is not present with the firmware I'm using, try flashing this and see what happens

Just for information for other users, the Nextel Mexico ROM works well with the Chilean version of the XT605. There is some bloatware, but it can be easily be removed with ES File Explorer or Titanium Backup (once you are root, though). Also, there are some OTAs available, that you can get before rooting (when rooting, you lose the ability to receive OTA updates).
hey guys i need the fastboot driver for this device i cant get rsd lite to recognize it
i really need it so if u can help somehow itll be pretty cool

[Q] Z2 l50u / l50t - sim not working on other roms [Solved]

Pitzmans said:
hello everyone,
a friend has recently bought a Sony xperia z2 for me from china and the model i got is the china unicom model (l50u)
the phone is censored on the stock rom it has, cannot use any applications that aren't Chinese government approved i guess (no google play, gmail, etc and you can only download Chinese apps through sony select which is in Chinese and cannot be changed)
this phone model is physically different than the rest of the sony xperia z2 (2.2mm taller, no mic holes, different slot locations )
anyway i unlocked the bootloader (before i really knew what it means, i wanted to root the phone) and then i flashed it with some other official roms using flashtool
when the phone runs on a different rom, everything works great except for the sim not working (the phone is supposedly simfree as it recognizes my not-china-unicom sim) and when its on the stock rom only the sim works and the phone is pretty much useless to me but a weird camera
before i started noobing around the device i updated its firmware through Sony's pc program which gave me the files to create the ftf file from and some more TA files in which one of the is called simlock.ta
i tried installing Emma and see if the phone is registered as simlocked but i couldn't get it to work (it seem like it is no longer for non-sony employees people)
so i ask you. is there any way for me to use this phone with a different official rom and make the sim work with it? is there anything i should know about? any help is appriciated as im new to this community (which i enjoyed lurking around in the past) and to this area in android devices (as i was quite pleased with the Os as is on previous devices)
thank you for your time, and keep being a great community
any help is appreciated

today i solved this problem with the help of Olberd and Chesterr
First i flashed to Generic Euro Rom from this thread
using Flashtool
then i rooted the phone using EasyRoot V8(check if your device works with it in it's current state)
then i installed SuperSU
then i installed Nut's Dual Recovery(locked) [you can probably check for a newer version and or change to an unlocked bootloader version]
then i flashed the radio drivers:
for the L50t (given to me by Olberd): Here
for the L50u (made by me using Olberd's files as a base*): Here
(put the driver zip on the root folder of the phone, restart and press the volume down button when the phone vibrates, untill the blue led lights, navigate to "flash zip.." and choose the driver zip)
now both the phone and the sim work, so far everything works fine ill update if there are any issues with the phone.
thanks everyone for your time and help!
*: take any of these 2 zip files and put your current original firmware's radio drivers - i used a root browser on the original firmware to get the radio drivers (copied them to a folder i can access normally on the phone) [search for the files you see in the zip].
NOTE : Use the drivers suitable for your phone, although they work on both phones they cause weird shutting down issues when installed on the wrong phone
Update : i checked all the links and wrote notes about EasyRoot , Nut's Duel Recovery and how to make the flashable zip file . i'm sorry but i cannot help with newer problems because i dont have this phone anymore as i posted before. i got some PMs and emails from sony support forum and im redirecting people here.
Update 2: apparently the google drive link became locked due to some google's change, so i updated the link so its downloadable again.

If your z2 is 2.2mm taller then it is the L50t China Mobile Model, The L50t uses TD LTE for 4G, the 3G is locked to China Mobile, but roaming with China Mobile Sim card is fine, it means you can only use China Mobile Sim card if you travel outside China. You can try to buy a unlock code, but only 3G will work, 4G LTE will never work unless you are in China.

Emma actually works. You need to copy the customization file when you initially extracted the zip, into the installation directory.
It was something that I actually missed too and there is a guide on Sony which tells you that. Once you copy that, Emma will work.

Have you found an uncensored firmware which works on the L50U yet?
BTW, its not the SIM that is disabled, its the whole GSM/UMTS/LTE radio functionality that gets disabled. My phone keeps telling me its in Airplane mode when its not. Also its confused about where the covers are for SIM/charger/microSD and keeps telling me I've left one open when I haven't.
Does anyone have the blob_fs files from C:\Program Files (x86)\Sony Mobile\Update Service\db\13740270\blob_fs starting FILE_ which you would get if you upgraded a real model D6503 to 17.1.1.A.0.402 as I'd like to try rebuilding the FTF but specifying model L50U in the build process to see if that would work?
If you have the blob_fs files for building the Generic FTF, then please post them here?
TIA

yea, the sim is unlocked by all means but it wont work on any other rom (i flashed a few : RU and UK unbranded ) both work fine except the SIM. (as far as i noticed everything else worked fine)
i posted on sony's support forum and got no help really.
also posted Here but nobody could help me
i got the "official" rom for l50u from when i updated it, i just have really bad upload rate and i saw no interest in it - i can upload it for you but it may take some time.(i also still has the FILEs )
i also tried flashing combination of roms (excluding things on the list) but that didn't work, and the new easy easy root didn't work on the l50u as well
i figured the only thing i could do is customize a rom like CyanogenMod using this? (their link is broken but if you change "other" to "copylefts" it works)
but i currently don't have the knowledge and more importantly the time and patience : |
a friend also took it to an official sony retailer but he couldn't do anything about it and also said the warranty is voided as i unlocked the boot loader before there was a way to back up the drm keys)
so tell me what you think and need from me and ill upload it for you.
thanks for your time and have a great weekend.
I am having the same issue with l50t phone, I was unable to get google apps to work on the china rom, and reading the forms they say it needed to be rooted to make changes to the host file.
I use doomlords "Z2_DooMLoRD_AdvStkKernel_FW-438-v05" after unlocking the bootloader, but that stopped my wifi from working. Mobile network still worked though.
Then I tried using cyanogenmod but had no service.
Finally I flashed it using "Canada - unbranded - 1281-9709" (I didn't back up the original) and still no service.
I have checked the IMEI number and it is still there.
Have you or anyone out there have an answer? Please and thank you

Unfortunately, I need help from those millions of people with a standard D6503 model, not us few who have the L50u and L50t models.
*YOU* reading this with a D6503 model - Please can you go to re-upgrade your working 17.1.1.A.0.402 firmware (no need to go ahead with the upgrade in reality) and send us the blob_fs files from C:\Program Files (x86)\Sony Mobile\Update Service\db ?
I'd really like to know if Flashtool can decrypt your D6503 blob_fs files and make a working L50u FTF from them.
Thanks.
Maybe someone can help me get going to get the SIM working.
What I've found is that the radio is turned off.
Dialed *#*#4636#*#*, but am unable to turn on the radio or select radio band (get "set [usa band] unsuccessful")
Also could not select preferred network type. I also can't change this under network mode in mobile network settings.
Please help me to figure how I can get network service.

well yes, you can read the issue i had in the quote on the first post.
when i flashed to other roms Google services worked (search, gmail, play store and i guess the rest too but i don't use them) but the sim did not.
so this method flashes a stock rom and installs the radios drivers basically.

Hi. I manage to install and flash successfully. But now I have another problem. My phone now is unable to have any signals. I am using China UniCom SIM card. I guess I need the L50U radio drivers files. And also instructions on how to flash the radio drivers files. Thanks.

LG V30+ H930DS regional restrictions

Fellow V30+ users and anyone else that has experience with recent LG devices, I have a H930DS from India that I use in HK now. It's the exact same model that's sold here in HK (I got it from India because of the lower price, which a first!).
Now, my problem is with VoLTE here. My carrier, CSL, supports this device and they even confirmed the same on call. It's duly listed on their website too. But, I do not get the toggle to activate it on my unit.
My software version says v10d-IND-XX, which clearly means it's meant for India. That could be the reason HK specific carrier information is missing on my device? This is my first LG device after almost 5 years, so I have no clue how LG does things firmware-wise. Samsung CSC stuff makes it possible to change regions, I know nothing about how LG devices work in that regard.
Does anyone have any information how I could go about fixing this situation? Can I change my region to HK? It's the exact same device, exact same software otherwise.
Thanks in advance!
I have exact problem in reverse, I have an h930ds from HK, using it in India. My carrier Airtel supports Volte but I can't see the volte toggle in my setting.
Any suggestions?

I'm planning to call up LG service on Monday and ask them directly. Normally, it's supposed to check the SIM and region on every boot and get carrier specific information accordingly (if that particular model is supported by the particular carrier of course). That's what Sony devices do.
So I reached out to LG support and after 3 days of back and forth, they came back with nothing. They have no idea if the region can be changed. They asked me to contact LG India, I'm not going to bother with that because I'm more than certain they would be of no help either.
Great news!!
Okay.. I bring good news! You can definitely flash any KDZ as long as the model number is exactly the same. I flashed the HK Reginal kdz on my H930DS from India and I now have working VoLTE and VoWiFi.
In short, get the CORRECT kdz of the desired region for your model number, use LGUP, Upgrade option, and let it do its thing. Simple. This keeps the device official and under warranty.
PS - Please backup all data before doing this. Even though it is just an upgrade, play it safe. Just in case!

Great news, where can I download the software and kdz? Thanks
Here's the link: ​LG H930DS Firmware Downloads
Please double check your region code (link to code list is at the bottom of that page).
To find the LGUP, necessary DLL file and instructions, check here:
https://forum.xda-developers.com/showpost.php?p=75293530&postcount=1
IGNORE the driver linked in that post, see below for driver installation.
PS - BEFORE doing any of the above, make sure you install LGMobile Support Tool on your desktop. Get it from LG's website.
- choose language and region in the program
- select LGH930DS and let it install the correct drivers (do NOT have the device connected while doing this).
- Right after driver installation, it'll pop up two archive windows, install both the files from those windows (one window is right under another, don't be too quick to close out the windows!).
- Restart Windows, then open up the program again and connect your device to USB and let it recognise the device. You need to select MTP (file transfer) mode on your device from USB options.
Now close everything and follow this:
- Connect your device (make sure battery is above 60%)
- Launch LGUP
- Let LGUP recognise your device.
- Select UPGRADE
- Click on the blank space next to the BIN File box and select your KDZ
- Click Start
- Let it finish (You can see progress on LGUP and your device)
- Device will restart
- Profit!
Warranty?

Hello,
I wanted to ask about the warranty of the device. For instance, I get a V30+ imported from HongKong to my country INDIA & if unfortunately the device needs some kind of service or repair, will LG India accept the device under warranty or will I need to get the service done from LG HK?

Hi,
Does your device come with B&O earphones? & can you please brief me about the warranty of the device since it is from HK.
I am kinda confused, I am planning to buy V30+ and I have two options H930DS and V300S, not sure which one should I buy, I don't see enough development for any of these, V300S is Korean version which will definitely have Korean bloat, on the other hand the H930DS is dual sim and I have a very bad bootloop experience with LG G4 dual sim variant, here in UAE the price of V30+ is almost equal to Pixel 2 XL 64Gb variant.

Yes the HK device came with b&o headphones.
1 year warranty, but only through the reseller i bought from, Wondamobile.

Rooted a Z5C, but several images caused "No Sim, No IMEI" Errors,

So, I had some microphone problems with a newly-purchased Xperia Z5c, got a load of lip from Sony about it not being under warranty at all, due to it having been "manufactured outside the US", and tore into them with the knowledge that no Sony Xperia phones are made in the USA. They folded, and sent me a new one, different IMEI, and the US model, the E5803.
So, I rooted the phone, but several of the "latest versions of android available via Flashtool's excellent "XperiaFirm" facility left me in a "No Sim, No IMEI" situation. I had to settle for a Marshmallow (32.2.A.5.11) version to avoid this. But somehow, I now have a phone that claims that it is a E5823 (non-USA) running Android 6.0.1 rather than a E5803, so I cannot restore my TA partition to the phone.
The good news in the above is that simply flashing a different OS image fixed the problem, there was no permanent damage despite the scary-looking lack of a modem and a SIM with the "bad" (or somehow incompatible) images.
Also, Flashtool refused to allow me to flash any of the E5803 versions of Android, claiming that my phone was a "E5823".
The questions that result are as follows:
1) How does Flashtool determine the model number for E5803 vs E5823 ?
2) How does one convince FLashtool to ignore model numbers and let one load what one wants?
3) I can understand how flashing a new OS image might change the model number, but are there any E5803 images out there that work? I sure could not find one.
4) Is there any way to restore a TA partition to a phone that has been "upgraded" from a E5803 to an E5823?
Thanks!
