Probably you hace lost your IMEI's flashing the official ROM.
Use MAUI meta to recover your IMEI's

I'm un official developer coming from fake ROM.
Red numbers in fake ROM but when flashing official one, they go, but in the update 7.3.23, they come back, and goes on in 7.3.30.
Ok. I don't know that. But if you want to install a chinese official ROM vía fastboot, you can do it with a Deep flash cable to force EDL mode, without unlocking your bootloader.

In my Mi5 with official global dev ROM don't appear the TV section, too. And I send the Redmi Pro APK vía bluetooth, and It shows the TV section again.

Ok, then you have to look for chinese versión oficial MI Remote ( think the last is 3.5.2), and install the apk.
