It might do. Just try it out. It's really bo rocket science.
On own terms. Thank you so much for providing this guide. Works like a charm for me vodafone card in slot 1. My telekom card in slot 2 doesn't have volte though. Is this only working for slot one in general, or is it my telekom card maybe?

Hello people, i've tried this methode with my Oneplus 6 on OOS 5.1.9 with the India Vodafone profile and its working great! Takes a little time to activate and seen in the pulldown menu but it's working perfectly. I'm on Vodafone The Netherlands.
Edit: Got only one problem everybody that calls me is unknown id?

working great! O2 - reseller
easy done, a shame, that oneplus settled on this.....

For me it is working to enable it but when I am calling, volte sign doesn't appear. So it doesn't work at all in Czech T-Mobile provider. I hope later it will.

doesnt work for me unfortunately (oxygen os 5.1.9, rooted, dual sim with premiumsim and netzclub, both o2)

It did work for me on 5.1.9 with premiumsim. Did you use the pc application or did you just enable the switches on the phone?
Does work with dp3 too Btw.

[Q] No service with Android 5, On Vodafone Germany. Any Ideas?

Hello xda-developers and thank you for reading this. I bought a new Nexus 5 today and flashed it with the original Google Lollipop ROM realeased some days ago. Everything runs fine so far but I can't get the service working. I've searched old threads to the best of my ability but couldn't find a solution, I hope you can. As said in the title I'm going with Vodafone Germany. Attached are some screenshots that hopefully give you all the information you need.
Thanks in advance!

No problem here with Vodafone Germany on my Nexus 5 running Android 5.0. Maybe your Sim Card is defect? Do you have another phone to test the Sim.
I tested the sim today on another phone, it works fine. I am currently testing different modems... I was hoping to avoid unlocking my brand new phone for a while but hey

Shouldn't be necessary to install another modem. Maybe it is a hardware defect? Do you have another Sim to test the Sim tray? Was it working on 4.4 before you flashed Lollipop?

I didn't test it before I installed Lollipop. It could be a Hardware defect (But I'd find that odd, I ordered it online and it runs perfect aside from the cell signal) I will return it if I get fed up with the issue, but that would mean no phone for another 3-4 days
Why do you think a different modem won't make a difference? A different SIM card did get a signal in Nexus when I asked for help in a vodafone shop I was if I recall correctly. But my SIM card also worked in another phone
Edit: I tested another SIM card just now, it showed service for a while with an exclamation mark (see attachment) but then went back to 0 bars
Edit 2: Also not working on Android 4.4.4

I'm not a developer, have you tried changing the preferred network type to wcdma only or gsm only in the phone testing menu?

Mi Mix3 VoWifi

Hi All,
Just wanted to check and see how is VoWifi (or wifi calling) working for you guys. I’m in Australia and has an Optus and Telstra sim in my mix 3. Phone is running the latest Xiaomi.eu rom.
I’ve search around google in general and found that to get VoWifi to work there is a need to swap the carrier profile on the Qualcomm chip which I’ve done. I have done did the *#*#VoWIFI*#*# code to disable carrier check. However I’m not able to get wifi calling working at all.
Thought I check in here and see if any of you have better luck and if there are any tricks that I’ve missed and needed to try.
Thanks
Hey guys, I just want to know that Mi Mix 3 support vowifi or not ? Or my carrier have to support that ?
I am confused
VoWifi works when on latest custom roms.

Which one does work? I could not find any confirmed VoWiFi for Mi Mix 3 yet.
Can't remember what rom it was but I have seen it somewhere.
VoWifi ("Anrufe über WLAN tätigen") is working fine for me - Vodafone Germany, Stock Global ROM. Also disabled the carrier check.

Do you have mix 3 or mix 2 ? I am wondering that I have vowifi enable button on same setup page but I don't have volte enable button. Volte already enabled. My mix3 running with android 10 miui 11.0.3.0.
I found my answer Mix 3 support vowifi. But my carrier doesn't support for mix3 vowifi..
Unfortunately it is not that easy with the Mix 3. I have a simcard with working VoWifi in a Redmi Note 8 but with the Mix 3 VoWifi with the same simcard is not working. So it does not relate to the provider only for whatever reason.
Give this guide a try. Works fine for me on K-Classic (O2 Telefonica Germany) on the latest stable MIUI EU ROM. Just make sure to switch to "prefer WiFi" suboption after disabling carrier check and enabling VoWiFi. I also had to enable the profile twice on sub0 for some reason...
edit: seems that's the guide you followed even though you didn't explicitly mentioned it? You should test that your phone does not default to another profile as mentioned here
Appreciate your reply. I found a way to change the profiles without root because I did not want to root the phone. Heard many negative side effects like Google pay no longer working and Android Auto can stop working. I need both.
But with an app call shortcut maker in combination with mbnloader I was able to switch profiles. I stopped testing after a while and gave up. I went for another provider now and will see if it turns out to work with the new one. If someone got the same problem, here the mbnloader:
https://www.google.com/url?sa=t&sou...FjAAegQIBBAC&usg=AOvVaw1dWx3npHTnHOpt9a3WkMjo
After installing "shortcut maker" by android_rk from play store and the APK above, start the shortcut maker and go for activities - modem - mbnloader to select another profile.

Three UK. Sort of working on global 9, same on xiaomi.EU 10 rom. Every few days I have to turn it off and on again to connect, but once done works flawlessly for another few days. Had to use the *# code to disable carrier check, as Three UK doesn't officially support it on most phones.

Is it possible to de-root the phone afterwards? And would you mind helping me by pointing me to the right direction for preparing my phone for this guide? I am a beginner and I find it hard to find the easiest way to root my Mi Mix 3.

AFAIK you have to unlock your bootloader to root, there is no exploit.
You'll have to get the mi unlock tool and probably wait 48 hours to unlock the bootloader, then flash twrp followed by flashing magisk from within twrp. Just look in the device forums for guides.
You can de-root afterwards, but I doubt locking the bootloader will work, as entries have been tampered with. Google pay/some banking apps might refuse to work after that, btw. There is a patch to gpay though.

Switch from china rom to global rom

Hello everyone, is it possible to switch from china rom to global rom? Anyone going to work on it? Thanks
I have exactly the same problem. The solution realme gives me is refund the telephone to China..

I've done quite a bit of research into this. It's not a simple process as for example Xiaomi.
It will involve resizing the system partition among other partitions.

Read in other forums that it's not possible.
There's a June update for our device, I got it this morning. A19
This last update does not includes spanish or changes anything
Hi, I have the RMX2075 (UK) and there is an update on the UK site for RMX2076EU, would this work if I installed it.
File manager detects that it is an update package. For reference it's the 17/6/2020 RMX2076EU_11_A.22
Currently on RMX2075_11_A.20
Thanks for any help - Josh

No sorry, this was a tangent regarding the RMX2075 (UK) getting the RMX2076EU update which was posted on the UK site.
Probably they just named it wrong. Sorry, I don't have the RMX2017 (CN) (but isn't it 2071 lol).
Just as an interest, what's wrong with the CN version?

As per my first analysis, RM2071 (CN) did not bring the majority of the languages (in my case, I need PT), just CN, EN and other two or three asian languages. It does not have Google Play store although it is possible to install it separatedly.
Finally there are many CN apps that comes together and when using EN, some untranslated texts in CN are still appearing in many screens.

Disappointed with Chinese Rom
I also own a RMX2071 version.
To be honest I'm disappointed as my expectations with this phone were too high.
Here are my remarks:
Breeno is only in Chinese and you cannot download EU voices,
Global search is only retrieving Chinese news,
Impossible to fully replace Breeno with Google Assistant (shortcut will still launch Breeno instead of GA, GA will not produce notification sound when activated...)
Some software and some rare options are not translated in my language (I set the FR language and still Chinese texte)
Security check is done for all app you are downloading from Google store (which leads sometimes to Play Store crash)
Google Chrome is freezing from time to time
I need to switch mobile data off and on to get back internet (specially after leaving the phone locked for a while).
I need to switch mobile data off and on right after a call or I'll not be able to get Internet...

How to Unlock Bootloader on OnePlus (Unlocked / T-Mobile)
Here is a complete walk-through and guide on how to unlock bootloader on OnePlus phones. Whether you are looking to install a custom ROM or trying to root
teamandroid.com
Contact @Whoareyou or u/whoareyouxda on Reddit.
He will provide his method for bootloader unlocking which worked for me. I'm currently running ArrowOS on my IN2019.
https://retry.abort.fail/vzwunlock/00README.TXT
I don't really want to post a thread regarding this method because I didn't write it up, create it, or test any part of it personally,
Also, the IN2019 is buggy on roms bc of hardware diffs and I don't want to troubleshoot every little issue everyone has, tired of getting so many pms though, if you really need help, try to find our telegram channel, I can't post the link to it here bc it pisses off the mods.

If you want to, I don't really have any opinions on it, I just don't want to be responsible for another thread of future problems .
I have run into all kinds of odd walls that the normal Samsung phone apparently doesn't have issues with. I am still trying to figure out a bunch of things to get everything to work right. Bought this oneplus 8 because I read that they are unlockable but now am finding they work just a little diff.
In this post, a user has found a way to unlock the bootloader. I can confirm it successfully works and I have currently flashed crDroid 8 on my IN2019.

Question LE2125 to LE2123 - can? How?

Have a OnePlus 9 Pro. Lost my dual sim function after updating to Android 13 in a weird way (it was ok at first). Now it shows only one. I want to revert to the European LE2123 as saw it can support it. I am in Hong Kong and seems this is the best option as I don't need the India version and I don't necessarily need Chinese (at least I don't read Chinese).
I have searched and gone down too many rabbit holes- so hope someone has been there already and can guide me.
Thanks!
David
Go to the 9 pro forum this is for the regular 9
