[Xiaomi Poco F1 Guides, News, & Discussion] parkiet1:
I extracted the mbn's from the sony xperia XZ2 (H8216). This phone contains a qualcomm 845, like our poco f1 does. My provider has certified support for the sony XZ2. The mbn from this sony phone seems to work much better for me than the mbn from the pixel phones (which is also targeted for the same provider) and the Xiaomi mi9t.

Attached the mbn's of the sony phone.

I used this tutorial to flash the mbn: https://xdaforums.com/t/guide-enabling-volte-vowifi-v2.4028073/
