Tried this. What I did :-
1. Disable all xposed modules.
2. Full unroot from SuperSU.
3. Boot into recovery.
4. Flash uninstall xposed.
5. Install xiaomi.eu ROM.
6. Install Magisk.zip.
7. Wipe cache
8. Reboot to system.
Waited for sometime, it was still stuck in the Mi logo and powered by android screen. Unless it takes longer than what I have waited.
