@Zer0 Think you can help out with our T-Mobile/Metro OP N10 problem? OnePlus has been refusing to unlock N10s that have been bought from eBay. So we recommend the unlocked BE2026 version. But, the T-Mobile/Metro versions are a lot easier to find.
Please see the N10 section of the forum, or join us on Telegram in the N10 or NA Issues channels.
@AntiMS The experimental Halium 12 build has two reports of succesfull VoLTE - both originating and receiving (non US), and several one way only calls with or without audio. I personally have tried it with all three US networks. Verizon has trouble, but with both T-Mobile and AT&T networks you can receive calls with audio in both directions. However, making a call fails and the dialer hangs. Logs were sent to the porter, and it is suspected that this is an ipv6 vs ipv4 issue.
We can help you more efficiently if you join the ubports NA Issues Telegram channel.
@AntiMS Boot into UT recovery. Enable adb, then either flash with the Google web recovery installer, or manually with whichever Google factory image you desire.
@UT-downunder Windows, yes. Linux users have gotten it to work either using a VM (requires a VM with USB port pass through. Some work, some don't), or by installing Windows to Go on a USB drive. Alternatively, there is a way to do it in linux somewhere in the ubPorts OP6 forum, but I haven't used it in years (I use Windows To Go on a USB SSD-Transend thumb drive SSD). Or just borrow someone's machine for a few.
@UT-downunder Replied to your other post - Flash the global build on the devices page with msmDownloadtool, then unlock again.
@UT-downunder It's already unlocked. But, if this is not the global build specified on the devices page, you should flash that with EDL mode and MSMdownloadtool (which is included in the build). Then unlock again.

You can also use the msmDownloadTool to completely reset everything, if you suspect you had a bad flash at some point. See the forum, same category as the above link.
@RandomUser Better yet, make a donation to the developer https://www.paypal.me/rubencarneiro
@tidip No, that does not normally happen. If a call fails, the dialer just hangs at most, not reboot.
There is an upgraded port coming soon that has 24.04 and VoLTE. You might want to wait for that.
Is your battery in good health?
@shengchieh Wish that last image was in focus. I'm suspecting you do not have the correct ROM on your device.
I would suggest getting the global ROM package Ruben specifies on the UT devices page and flash it using EDL mode and MSMdownloadTool. Then try again because you are following the steps correctly.
Just FYI, it's easier to help you via the N. American Issues UT Telegram group.
@oldbutndy Google has not released control of RCS enough for us to do anything with it. There is a $10k+ bounty out for whomever first achieves it.
VoWiFi works by signaling over the VoLTE carrier channel to use the data channel (WiFi) for the voice part and not the carrier channel (audio can be sent via either channel). We need a button and a hook in halium to manually turn that on. There has been one report of a person who set that on in android and it remained after flashing UT. But that has not been confirmed by others. It could be it just does it without needing a button if it was already enabled, but we do not know.
@shengchieh Are you booting to fastboot where the phone just shows the select English or Chinese option? Or are you getting to the multicolored text only screen that says fastboot and other info? If you are not seeing that text filled screen on the phone, then on the computer try the comand: fastboot reboot fastboot.
Just FYI, there is a new 24.04 port in progress for OP6/6T. The porter says it is almost ready. Ports for Pixel 4 and 6 were never finished.
There is also a new halium 12 port in progress for p3a. You can test it now. Instructions are here in the forum.
@shengchieh
On Computer input adb reboot fastboot
In fastboot menu on phone select English or Chinese
Select advanced reboot to fastboot.
You should see original fastboot menu, not fastboot2 on the phone.
On computer, enter fastboot flashing unlock. It will either prompt you for a token, or ask you to select yes to unlock.
Consider testing out the new halium 12 port with VoLTE. Need more testers to work out the bugs.
OnePlus phones are very hard to brick. They can be recovered using the msmDownloadtool usually included with the image on the UT device's webpage. If it isn't, xda-developers has them, for every OnePlus model.
@Leroy_Linux We experimented with SIP in the dialer and it is capable of making and receiving VoIP calls. Audio routing needs troubleshooting as it could only either send or receive audio, not both. Also, it could stand to be integrated better so that it is prettier and the dial buttons show up during calls. Any help with that would be appreciated. We have a telegram group just for this subject.
