1) Use latest Official TWRP version (or OrangeFox R11.0 Unofficial for davinci, my prefered custom Recovery).I was on an AOSP based ROM and I didn't follow the instruction correctly. So I decided to roll back to an old firmware using MiFlashTools, thing is that the only firmware I had in that moment was an old MIUI 10 so I flashed that. I formatted Data after that but got that error when I reboot :/
2) "Format Data" then reboot to TWRP/OrangeFox, then install xiaomi.eu ROM.
