Any ROM to get VoLTE, WiFi-calling ? - Huawei Mate 9 Questions & Answers

Not sure if a question about ROMs is appropriate in this sub-forum, if not, hopefully a friendly moderator will move to aa questions sub-forum.
Happy with Mate 9 Pro except that there is no US ROM for it, so mine has Taiwan (C636). Therefore i do not get VoLTE or WiFi calling on my T-Mobile.
I did check a long time ago that VoLTE is seemingly simply enabled through XML config files different across different regions of the firmware, so it should be easy to create a ROM where those XML files would try to enable VoLTE for the US carrriers. Not sure if this is all thats missing though. But maybe someone has tried. Even better, someone has tried and succeeded in building a ROM that has those XML fixes.

same here in south africa no options for VOLTE netwwork does support it

Disregard this comment.

I accidentally got VoWi-Fi, rebranded l09 to l29c636 and then installled latest firmware from the firmware finder for huawei app( 8.0.0.362),
when booted it said my network was '3 Wi-fi calling' And it worked. delighted because i had been using a seperate app for this service but since deleted it.

I got it with my upgrade to Android 8. Device: MHA-L29C567

I'm on SafeLink - the Obama phone plan, AT&T Network.
And yes, I got it when I was working. Would love to get back to work and love to get a 10" Octa-Core phablet as my primary phone, and a Mate 10 or a smaller Huawei as my 'pocket' device. Sadly, entering my elder years also means entering dire medical problem years. Perhaps next Christmas I will be able to do something different and get back into the new tech.

Get volte in mate 9
Rebranded to l29c900 and now VOLTE is working for me in my mate 9..

Calling all mini owners

Calling all mini owners, donate to tdm, found a mini for $100 and sent him the info for it.
He has been working very hard to bring us root, now let's bring him a Dev phone!
Unlocking, root and custom ROM will come a lot faster if we get a device permanently in his hands.

I guess you would have to pm him to ask how you can donate to him, I thought he had a link up for donations.
I'd take the donations and buy the phone for him since I live closer to the seller, but I don't know if he got the PM I sent him about it and bought it or not yet.
He's gotten the device, use the link in the op to ask how you can donate to tdm and offset the cost, he plans on releasing custom roms soon.
Very exciting time to be a mini owner.
I'm excited and can't wait! I'm coming from a Nexus 5 and Nexus 5x those have very good development support, I can't wait to start flashing ROMs and kernels on this mini!
Hey @fallen00sniper hope you don't mind me hijacking this thread, but I wanted a place to update everyone on progress and I didn't want to start a new thread.
Current status as of Oct 3 2017
Unlock
Unofficial unlock tool has been released.
Waiting for official ZTE unlock.
TWRP
Alpha version posted in unlock thread. This uses the binary kernel and init from stock (including enforcing selinux) and does not have decrypt support, so it is not optimal.
Working on a full source build and eventual official TWRP builds.
Custom ROMs
I have just now successfully booted the device with a source built kernel based on the ZTE provided sources. I'm starting on Lineage 14.1 support. This will probably take at least a week or two.
Once Lineage 14.1 is working reasonably well, I will also do an AOKP build since that is my preferred ROM. I can help community members with other ROMs, but I won't maintain them myself.
Other
Collecting information on regional variants.
@saymonek has a single-SIM UK/Europe version that is reportedly stuck on 6.0. Are there any more variants?
@tdm, completely fine by me.
while you are in the rom getting them up and running, check into why the touch screen sucks at positional tapping, mine isn't 100% accurate lol
Did a bit of research on variants by trolling through ZTE support. So far I've found:
* USA version.
* UK Carphone Warehouse version.
* International "open market" version (eg. Austria).
* Hong Kong version.
First build done:
Package Complete: /home/tdm/out/laos-14.1/target/product/tulip/lineage-14.1-20171003-UNOFFICIAL-tulip.zip
This is going to need a fair amount of work before it boots and runs, but ... progress!
Oh also FYI... I've been cribbing from the HTC One A9 (hiae) device for Lineage builds. haie is maintained by intervigil, who I had the pleasure to work with at cyngn. I'd say he is one of the top four or five device people in the custom ROM world. And it looks like he has been actively working on Lineage 15.0 so we should get that soon after nightly builds start.
It's so exciting to see device development take off!
Just a quick update...
I had a ... uh ... "server malfunction" yesterday so didn't get a chance to do much. However, I'm back in business today.
So far today I've got linage to start the boot animation. Should be able to get all the way to the home screen tomorrow.

Hello, can I change my axon 7 mini back to the US variant? It was originally US variant, I mistakenly switched US band in the engineering menu and Iost network services. I managed to get it working with the European firmware from ZTE Russia. Would like to revert to the US variant. I noticed in the bootloader version, the US version is P852A12 whilst the European variant is P852A11. Any luck on reverting to US variant?
Can you not access the engineering menu and switch back?
If not, my suggestion would be to use QPST and/or QXDM. These are proprietary tools but you can find them for download. They will allow you to program the frequency bands that your phone uses.
Good luck.

I can access the engineering menu. The device is working but would have loved to switched back to US variant because it's a US variant initially but I am unable to install the US firmware I downloaded from ZTE US Support site
I'm sure we can get you back on US firmware.
What is the error when you try to flash the ZTE package?

Ebay bought Mate 8 not updating..?

So I bought a (supposedly) sealed Mate 9 on ebay as a Christmas present to myself, and it's great! but i'm not getting any updates.. its an MHA-L29, Build no MHA-L29C432B182-log.
I'd previously been onto Huawei on facebook with an update query on my Mate 8, so I queried them about this phone with the same question. This was what I got back:
Hi Fred,
Thank you for getting back to us.
We have tried checking the IMEI numbers of your Mate 9 device in our system and although on the consumer website we were prompted with the information that the device is intended for China, while running them through our other software tools we were unable to gain access to any type of information.
For this reason we won't be able to provide any details related to the current Build Number available for the device, or any other details related to the updates intended for it.
Should any other questions arise, please do not hesitate to contact us.
Best regards, Huawei
So it seems it's a China model and not a European one. Do I somehow flash it with a Chinese rom? If so - which one?!
Any help much appreciated!
Fred
I wont be much help on this subject, but you would certainly rebrand to a different region. There are a few threads around for that, Then use the region you want.

So, it is definitely Chinese model.
1. Huawei didn't tell you much info, just point to China.
2. Model that is selling in Europe can't have log suffix in build number. This is ROM for test purpose with logging and sending info to Huawei. Chinese sellers flashed it by inadvertence.
Don't look on it was sealed. It is too easy to seal box again.
Well, you can stay at C432 region, but I recommend flash release version like B198 using Firmware Finder.
Otherwise you can return to Chinese region ( C00 )
In this case you must get unlock code and unlock bootloader. Turn "oem unlock" in developer settings and remember that option is on world ROMs only.
Then you will able to rebrand.
Thanks for the input so far guys,
Would there be any benefit in putting a Chinese rom on? Am I right in thinking that China versions are getting Oreo at the moment? I'd rather not go through using the tool and rebranding (did it before with my Mate 8) so I think i'll try to work out the firmware finder app!
Thanks

I believe the Chinese versions are somewhat limited and cannot access some Google apps and services.

Good morning all,
I used the Firmware Finder to update to MHA-L29C432B198 and all good! Now I guess I just wait for the Oreo update to hit this region version. It needed a reset of course, so I had a fun evening of rebuilding and signing into all my apps while at the same time completely rebuilding my media centre pc which had refused to boot.. yay. Good times.

Well, even if you updated, you're still "out of region". So chances are you won't get any update to Oreo.
Oreo builds for C432 are named MHA-L29 8.0.0.xxx (C432) in Firmware Finder, same with MHA-L09.
So you could try updating to Oreo through FF.
Thanks, I'll keep checking the finder app. I'd rather stay on the c432 chain as I'm in England if that makes a difference. Is Oreo still in beta for 432? So far they all say not approved for installation.

Installing new firmware/unbricking via eRecovery: SUPPORTED
Rebranding with unlocked bootloader: AVAILABLE NOW!
Rebranding with locked bootloader: COMING, MIGHT BE A WHILE
Unbricking from fastboot: COMING, MIGHT BE A WHILE
Since it is a new device on a new OS, some things have changed and we need to update some of our methods to fully support it.
Those who would like to test rebranding with an unlocked bootloader before we release it, please contact us.
Frequently Asked Questions
Q: How much does FunkyHuawei cost?
A: You need to buy credits on the FunkyHuawei website. The price per credit varies depending on the number of credits you buy. Different operations cost different amounts of credits. However, the Root feature of the Mate 10 tool is free, and as mentioned above, Recognized Developers/Contributors of XDA can ask for a free credit.
Q: My phone is bootloader locked, and FRP locked. My bootloader unlock code dosen't work. It won't boot. eRecovery doesn't work. Can you help?
A: Yes. With the Mate 10 this is now a common situation. Contact FunkyHuawei for help in this situation. We'll need to access your computer remotely and the procedure is a little bit complicated, but the phone can be unbricked.
Q: I can't get my bootloader unlock code/don't want to unlock my bootloader, but I want to change my phone to something other than Chinese. Can you help?
A: Yes. Our new FunkyHuawei Rebrand Tool works on recent Huawei phones (Sorry EMUI 8.1 phones not yet supported. Coming soon), to rebrand them to another region even when the bootloader is locked.
Q: I'm not seeing the latest version listed on FunkyHuawei or elsewhere as an OTA. Why not?
A: Huawei has a very odd and unpredictable way of rolling out OTA updates. You can use FunkyHuawei to install the new version immediately, or can wait for the update to be rolled out. It might be a month or more after release until the update reaches your device from Huawei directly. We have no idea why.
Q: Why isn't FunkyHuawei free?
A: Because many of FunkyHuawei's features cost FunkyHuawei money to provide. Features that don't cost FunkyHuawei money to provide, like rooting the Mate 10 or our TWRP build for Mate 9/Oreo, for example, are generally made available for free. There are also bills to pay, kids to put through school, and so on.
Q: I noticed FunkyHuawei in an XDA Portal article!
A: FunkyHuawei loves XDA, and is cooperating with them as much as possible. Recognized Developers and Contributors on the XDA forums are welcome to claim a free credit from FunkyHuawei as well.
Q: I have a different question.
A: This is what this thread is for! Post away!
We now have the following firmwares available to install with eRecovery method:
CLT-L29 8.1.0.107(C432) - European
CLT-L29 8.1.0.107(C636) - Asia/Pacific
More will be added soon.
CLT-L29 8.1.0.108(C185) now available for Middle East P20 Pro.
We have successfully rebranded the P20 series. Tools will be released pretty soon.

Yes. But it's possible the phone has an internal secondary IMEI which it simply doesn't show on the settings. We haven't had a way of figuring out exactly how it works IMEI-wise, but both sims do work. It's been this way for generations of Huawei phones.

Chinese OnePlus 7 Pro- get Google, flash other ROM

I live in China so currently I can only buy this phone customized for China- no Google apps and only some local crappy app stores.
I know it's possible to install Google services/store etc. on Chinese phones, but would it be possible to just flash some stock "Western" ROM on it?
Are there any stock ROMs from OnePlus available for international versions?
How can I tell if the phone I'd be buying here is "flashable"- how can I check it at the store ?
There are all 3 versions available here (6/8/12GB ram)
Chinese version uses hytrogen OS, you can try flash oxygen OS(stock os on international version)through "local upgrade" .
Some personal experience:
I bought Chinese version too and I directly flashed zip in this thread through local upgrade, the OS changed to Oxygen OS as expected but Google play store somehow wasn't installed, so I factory reseted my phone, then everything works fine now.
Note: Chinese version got a system update after it was released if you performed that upgrade you may not able to flash oxygen os because version number(9.5.4) is higher on hytrogen os than on oxygen os(9.5.3).
Note 2: This thread provide 9.5.4 oxygen os now so if you already performed upgrade on hytrogen os you can try flash 9.5.4 oxgyen os.
Hi, I'd like to hop on this thread to ask a similar question.
So right now I'm in China and will stay for a few weeks. I've been wanting to get my habds on a 7 pro since I learned about it, and I'll be residing in S.Korea for the foreseeable future.
I have an option to purchase the device from the US official website and have an agency deliver it to me at my Korean address (I'm assuming the US version retails as the global version GM1917 I believe?). All in all it'll cost around $790.
Or I can purchase the cheaper, chinese version while I'm here and install the Oxygen OS on it as I'm told it's a rather simple procedure for Oneplus phones. I've never tried any sort of unlocking/bootloader/flash/custom rom stuff so I'm not entirely familiar with all this but it seems doable if i tread carefully.
The question that stands however, is whether or not there will be any difference at all between the two. I believe the Chinese model is named GM1910, I'm assuming there are some hardware differences like band support, but then again I can't find a clear answer on this. I've also heard that flashing the OOS might mean it wont be google play digital certified (not entirely sure if i got the name right or what it does) and I might encounter widevine issues. But then again I've seen people mention the hardware is the same so as long as I convert the OS it should work like a breeze as if it was the global version.
I'd appreciate any help and guidance in this matter. Also by flashing the OS would that mean I'd have to manually apply OTA patches whenever they're released? I'm not too concerned on warranty issues but if you guys have anything crucial I should keep in mind about it I'd be grateful for the help.
Thanks in advance.

All version sold in china is "flashable", just pick up the specs/color you prefered.
For the switching the system from HOS(Chinese version) to OOS(global version), it's simple:
1. flash the newest Oxygen OS(GM21AA, for global version) through system update;
2. reboot to recovery;
3. wipe all data of your phone
Done.

Widevine downgrading(L1 -> L3) happened when you unlock the bootloader. If you just get an chinese version OP7P, switching system from HOS to OOS, it's ok to do it through system update, while maintaining the widevine level.
After switching to OOS 9.5.3, my chinese version OP7P works pretty fine with all google service(except google pay, no environment to test it)

So right now I'm in China and will stay for a few weeks. I've been wanting to get my habds on a 7 pro since I learned about it, and I'll be residing in S.Korea for the foreseeable future.
I have an option to purchase the device from the US official website and have an agency deliver it to me at my Korean address (I'm assuming the US version retails as the global version GM1917 I believe?). All in all it'll cost around $790.
Or I can purchase the cheaper, chinese version while I'm here and install the Oxygen OS on it as I'm told it's a rather simple procedure for Oneplus phones. I've never tried any sort of unlocking/bootloader/flash/custom rom stuff so I'm not entirely familiar with all this but it seems doable if i tread carefully.
The question that stands however, is whether or not there will be any difference at all between the two. I believe the Chinese model is named GM1910, I'm assuming there are some hardware differences like band support, but then again I can't find a clear answer on this. I've also heard that flashing the OOS might mean it wont be google play digital certified (not entirely sure if i got the name right or what it does) and I might encounter widevine issues. But then again I've seen people mention the hardware is the same so as long as I convert the OS it should work like a breeze as if it was the global version.
I'd appreciate any help and guidance in this matter. Also by flashing the OS would that mean I'd have to manually apply OTA patches whenever they're released? I'm not too concerned on warranty issues but if you guys have anything crucial I should keep in mind about it I'd be grateful for the help.
Thanks in advance.

I'm not sure if there are any hardware difference between Chinese model and other model, but I'm sure Google play is still certified on Chinese model after flashing OOS. Widevine level won't change as long as you don't unlock bootloader and you won't need to unlock bootloader if you only want to flash OOS.
I used to have a Chinese version OnePlus 5, I flashed OOS on it and everything works pretty well for two years, OTA always works. I assume everything is the same on OnePlus 7 pro.

All version sold in china is "flashable", just pick up the specs/color you prefered.
For the switching the system from HOS(Chinese version) to OOS(global version), it's simple:
1. flash the newest Oxygen OS(GM21AA, for global version) through system update;
2. reboot to recovery;
3. wipe all data of your phone
Done.

Hey, thanks for the reply! for some reason I can't quote the edited latter part of your post.
It's great to know its as simple as you said. But like I mentioned I'm quite new to all this so I hope you're fine that your answer also raised some questions for me.
So if there's no influence on widevine, why would people go the extra effort to unlock the bootloader? Isn't it primarily to flash a fresh ROM which would mean the end goal is basically the same is it not? Would my OS converted phone be any different to that of a bootloader unlocked one in regards to performing identical as a global version 7 pro?
Thanks so much for the help!

People unlock bootloader because they want to root their phone or flash third-party ROM. Bootloader has to be unlocked if you want to flash anything other than stock ROM or other stock things.

Thanks you are amazing. I think I can safely go with the Chonese version. One last question though, would tweaking for VoLTE require any rooting?

Glad I can help.
If you're in China, I don't think you need to tweak anything to use VoLTE no matter which OS you're using (Hytrogen OS or Oxygen OS), there are three main telecom operators in China: CMCC, China Net and China Unicom.
CMCC already support VoLTE so if you're using CMCC's service your phone will enable VoLTE automatically once you plug in the SIM card and detected signal.
China Net added support for VoLTE very recently, so VoLTE should be automatically enabled too once you plug in a China Net's SIM card, but I'm not sure about this because I'm not using any China Net's service.
China Unicom does not support VoLTE until June 1st 2019, you won't be able to use VoLTE till then in any method if you are using China Unicom's service (Google Fi and some international roaming use China Unicom's service so no VoLTE for Google Fi and those roaming yet)
Dual VoLTE with dual SIM should work too, I'm using CMCC and China Unicom dual sim and VoLTE icon on my status bar have a "1" next to it(VoLTE1), I think there will be a VoLTE2 after China Unicom support VoLTE.
I know little about these Telecom operators things outside of China, but I think Oxygen OS support most country's VoLTE service as long as their Telecom operators support VoLTE.
I'm new here, my op7 pro is on the way to me, I'm in China too, so I should unbox it, do not upgrade, download the oxygen os and flash it directly? Than I'll get a "global version" op 7 pro, will it work?

SIM Setting Issues after Flashing New Xiaomi.eu ROMs

Trying to figure this one out and maybe just something small I'm doing.
If I flash anything higher than the 11.0.12 release of stable from xiaomi.eu, my sim card settings seem to not work right. I have dual SIM. TMobile and redpocket. On 11.0.12, I can get 5G on TMobile and 4G on redpocket. Past that, it switches to only getting 4G on TMobile and H+ on redpocket. Am I doing something wrong or did they change something. So confusing...
Any help is appreciated

did you figured it out?i installed eu but no 5g
No I didnt. Even more disturbing is that the newer ROMs also seem to take away an additional band of connectivity with TMobile rather than the base China rom. I would of considered keeping my Mi 10 pro if I could rom without this issue, but losing this connectivity is making me get a different phone. Really stinks

LMAO,
Simply flash the modem from your firmware and the issue is resolved. Easy!
Different roms from different regions use different modems with less or additional bands. Flash the modem from the rom that works. I would recommend using LR Team or orangefox recovery.

I thought about that and will try it if I decide to keep the phone... I'm probably going back to the Find X2 Pro... I got the Thailand version coming soon... I'll probably just relock the bootloader on this phone. The Find X2 Pro has way more capatibiilty in North America. The Thailand version has global rom and dual sim.... Where as EU is single sim....
I like that I can rom on this phone but I'm getting too old for it. Hahaha. Just want the best phone for the money. This phone is great and is probably the better value over the Find X2 Pro but the lost of bands especially not working with Verizon MVNOs stinks.

I also live in the US, I agree that you should sell it soon while, it is still highly sought after.
I was within an inch of buying a Mi 10 Pro myself, I have been wanting to upgrade from my current Mi8. Fortunately, I found that the Mi10 and Mi 10 pro are lacking too many bands for the US before I processed the order based on inaccurate info.
As of right now, Xiaomi doesn't seem to care about gaining or maintaining loyal customers in the US or any country in North America, for that matter. If they did they would releases phones with more than 3 compatible bands for AT&T and TMobile. Without a doubt I agree that you are better off with an Find X2 Pro or a One Plus. - Note how those phones have every single band, for every country!
To be clear, there are many things that I love about Miui, but Xiaomi phones offer less bands with every release, and the last phones that had more than 3 bands for the US was in 2018 with the Mix 3, and Xiaomi Mi 8, the Mi9 was released with only 4 compatible bands. To go on, the Mix 3 5G has received no updates in a very long time.
While, I suppose that you could get by with 3 bands, you will not have a signal in some areas. and here is some additional info that for me is just another nail in the Xiaomi coffin. Historically, Xiaomi has supported their phones for 3 to 5 years ( like Apple)
However, last week Xiaomi management decides to stop supporting all phones with SD 845 processors, starting in September! These phones are currently only 2 and a half years old. Here is a source I have no idea why they are shooting themselves in the foot with these bad decisions, but if they go down in flames another company will rise and take their place. Finally, I am sure that you have seen the news about the recent security issues with browser tracking even while using incognito mode
Hopefully they get their act together.
Good Luck.

It's been awhile but I think there's 2 possibilities
I pretty sure that you could just put the modem file from the China rom into a file like modem.zip and flash with TWRP... It's been a moment and I might be wrong on that. You could also replace the modem file in the EU rom zip file and flash as well

You can just dirty flash the latest global firmware for your device ( if it's a global device) Download it from the Yshalsager firmware website. It includes the modem and radio drivers.
https://xiaomifirmwareupdater.com/. FYI the site also includes Chinese and Russian firmware.
Always create a TWRP backup and copy it to a secondary location before doing these kinds of things. ( USB or desktop) Just in case. However, I do this type of stuff all the time without issue. We have 4 Xiaomi phones in my house.
FYI, you will only find the modem file in fastboot "images" roms.

As I mentioned It must be an "images" fastboot rom. FYI: These roms are the same roms that you also use should should you ever have a brick...nothing else will work to unbrick a phone. So be sure to keep it and also be sure to make a full TWRP backup and keep it on your desktop so you will have a way back if something terrible ever happens to you such as losing sensors, IMEI, persist etc.
For example, see my screenshot

Just so you know: You can extract the files individually and flash them.
Plus firmware flashing doesn't affect the system installation because the firmware lives on it's own partitions . FYI: Generally Android phones have on average around 20 or more partitions depending on the phone and the OS is on its own partition.
These image ROMs are hard to find so I would strongly suggest that you look for, the native images Rom specific to your devices.
If you can't find it on the Mi-Community website, try use Chrome with Google translate and switch Mi-Community's region to China, then you should be able to find it. You can also find links in telegram. But personally I don't trust firmware from 3 party sites. Especially Chinese 3rd party sites that often add additional adware.
Also, if you weren't aware be very careful about using Mi flash and accidentally locking your bootloader.
Enjoy your phone: I had planned on buying one myself but it lacks way too many bands for North America to justify the expense. Hopefully Xiaomi actually builds the rumored upcoming Mix 4. The Mix series usually have every band.
