I can confirm that it does bootloop on the EU Rom..

 

[porozex]

I can confirm that it does bootloop on the EU Rom..

Flash Eu rom again without wiping anything then reboot
Boot back again to twrp flash the kernel then reboot don't flash magisk do it after a reboot.
It should work like this

Hello @nysadev !!
installed in xiaomi.eu MIUI weekly 9.4.25. To avoid falling into bootlop followed by installing the kernel you must install magisk !!!! Another thing I do not have audio after installing the kernel version 1.3, the phone slows down!

I will be testing all the versions I take, and I will inform you if everything is ok or there is something to repair !! Very grateful with your work!

Lyra 1.4 - Stable & Developer kernels
Changelog:
- Move to two seperate builds. You will need to know yourself which kernel you want to use. MIUI developer versions will of course use the developer firmware builds, my ROMs and most other AOSP ROMs are stable too. You'll need to know.
- Switch to a new, adapted energy model
- Fix SD cards breaking on MIUI
- Some other optimizations
