This is a new custom MIUI based on xiaomi.eu, our target was make smoother and with better battery life, for do it we used stock china vendor, and our boot patched with preinstalled magisk 19.3.

(if magisk manager propose to update, decline because magisk 19.4 is still canary so not stable. Go in magisk manager setting and choose as channel for update stable)
