Bugs:
• Fingerprint is not perfect
You need to turn on option "long press fingerprint sensor to unlock" to enable biometric fingerprint unlocking when screen off. If fingerprint enrollment failed, please reboot mobile and unlock with pure password rather than press fingerprint sensor. (biometric payment method seems to not work)


Steps:
Flash MIUI eu v13.0.3 (https://xiaomirom.com/download/xiaomi-12x-psyche-stable-V13.0.3.0.SLDEUXM/#europe-fastboot) via miflash. This step maybe necessary for boot but for functions
Follow one-click tool to accomplish the process.
Flash audio related magisk module provided
Yc Scheduling

The power consumption lasts about 10h, and the fingerprint will increase the power consumption. The prower consumption varies according to use conditions.

FAQ 1: How to flash in?
Use the bottom package v13.0.3 eea (European version) to brush in, and then follow the one-click beta tool (password: m12x ) .Then flash magisk module in the tool content after extacted.

FAQ 2: Fingerprint correlation
If you need to unlock the fingerprint, please open "Long press the fingerprint sensor to unlock the device", which can be unlocked in the off screen state; If the fingerprint cannot be added, please restart and use the password to unlock in which process touching senor may makes fingerprint enrollment failure and add again.

FAQ 3: Mobile network cannot be used
Select the preferred network GMS, and then add an access point APN. The first two lines of cmnet (mobile) are saved and selected. Then you can select 4G or 5G NR. Please find the relevant access point settings for other operators
