Xiaomi Redmi Note 9T 5G (cannong) repair imei [Answered]

Dear Z3X team,
i need to repair the imei on the xiaomi redmi note 9t 5g (cannong) M2007J22.
At the beginning I clear the nvdata and nvram. Then I repair second imei.
As a result phone find network only on sim 2 (is it correct? qualcomm with null imei1, connects to network on sim1 - for example redmi note 9 pro) but only on lte mode. 2G, 3G doesn't connect. I can't call to 112. If the mobile network doesn't support voice over lte i can't make calls or send sms. I suspect the nvdata file contains radio calibration data for 2g, 3g because when i restore backup nvdata i can call to 112 and network connect with 2g or 3g but the oryginal imei is back.
Please help me with repair.
Best regards

Hello. Try repair with new dualsim method. You dont need to erase nvdata and nvrav, just repair and after patch cert.
