That's exactly why I have the zoom too! Apparently it doesn't but buying a phone directly from China from the Chinese market basically comes with no warranty anyway!! Haha

I have k30 pro zoom in the UK, with EU ROM and it's fine without B20. The band's cannot be changed, added or removed with a change in ROM so if you really need B20 get Poco.

I'm on MIUI 11 stable and a few weeks ago I had a failed CTS, I done nothing and now I have a passed CTS. Any ideas?

Put phone into fastboot and then follow the instructions. Look for installing TWRP from XDA forums should give you enough information to get it flashed

First of all please don't mount this to your Windows PC!
All the steps are in the first post of the MIUI ROM posts.
1. Unlock bootloader
2. Setup ADB
3. Flash TWRP in fastboot
4. Wipe phone (full wipe)
5. Install ROM
6. Enjoy
