New device not certified - Mi 10 20.11.18

[Torihum]

Hello, i installed the new Version 20.11.18 on my Mi 10, but Google play dont work, so i installed safetynet check and my device dont pass the test.
CTS Profile Match Fail.
On play store Is written "Device Not Certified".
I never had this type of problems.
I havent root, magisk or other things.
I only have OEM Unlocked to install xiaomi.eu Rom, nothing more.
Why i have this problem now?

Hello!

SafetyNet fails because of the new SafetyNet's "hardware" attestation by Google, applied on some devices like yours (=now detecting if your bootloader is unlocked by a secure hardware key info).

Workarounds are available here (you can only do the second or third one on your phone) => https://xiaomi.eu/community/threads...t-failed-redmi-k30-pro-zoom.57923/post-567224

I Locked again bootloader but dont change.
Why the beta of 1 month ago or the stable work without problems?
Maybe because Android 11?
I havent magisk.

Maybe... but can you install "Magisk Manager" app and open it to check if SafetyNet is using "Basic" or "Hardware" (to be sure) => MagiskManager-v8.0.3.apk

You can delete the app after that.

Hardware, CTS profile

Hardware, CTS profile

Ok, so you can only fix it with the "Magisk" or "persist partition" workaround (from my previous link).
