Problem fingerprint mi 10 pro(solve)


Do * # * # 6 4 8 4 # * # * and enter the test menu. Click on the 3 dots on the top right and additional tools too. There is fod fingerprint calibration at 11, click on it and before starting the test, put a mirror on the white place where the sensor is, after completing the test, then put something black on the white place. The fingerprint will come back after the test is over. It did not add fingerprints on my head, I solved it with this method, but the fingerprint does not read as before, maybe because I could not calibrate well
 
With so many ROMs back and forth one new one the old one I discovered that the fingerprint doesn't work and I don't know how to fix it I've done two or three times fastboot rom and again it doesn't work if anyone knows let me tell you photos tell me what it can be and where i can find it
You solved problem ? Can share solution please ?
