Null IMEI / Unknown Baseband

[Kararens]

Hi. My device is Poco F2 Pro...

Last night, my phone froze and became unresponsive. I forced reboot it by doing Power Button + Volume Rocker Buttons. After the phone rebooted, my 2 SIM cards were not detected anymore... I tried flashing other ROMs - both recovery and fastboot ROMs, but still no luck.

It seems that my IMEI were lost, and the basebands became Unknown...

Any way to fix this please?
