Mi 11 Ultra Fingerprint not Working after Display Repair

[PhoneCenter]

Hello there!
I've seen a similar post but it didn't help me with my problem.
I broke my Mi11 Ultra the first week I got it, so I bought a replacement screen from AliExpress (since Xiaomi Support Germany didn't want to sell me one for my Chinese Mi 11...).
It was a screen unit with frame and buttons.
After putting the phone together Everything works except the fingerprint scanner.

I tried calibrating it like shown in other threads (I own a Relife calibration tool since I run a repair shop). Didn't work at all, failed at first step.
Then I rooted my phone, deleted the goodix folder and now my calibration page looks like on the pic.
I'm so done with this phone and Xiaomi after what I went through, I just want to get it fixed and sell it ASAP.

Please anyone, what can I do I'm so tired and done...
Best regards

I calibrated it with a clear eraser cut out a square with a serrated knife cut straight through and it worked great

A Friend of mine just got his display repaired by the official Xiaomi Germany repair partner company in Flensburg (Ingram Micro Services GmbH)

The fingerprint is working and he got 24 month guarantee, it's quite pricy though but his insurance paid the repair.

So, they do repairs and they don't care whether it's import or not.

This doesn't help in your case but generally speaken

Regards.
