Problem Fingerprint Sensor Mi5s

[Mastrr]

Hi, I have a mi5s for a long time. At first everything worked well but one day the fingerprint sensor stopped working. I erase the fingerprints that had been saved to save them again and now it will not let me save them. Now he does not let me keep any trace, he gets caught on the screen that says "put your finger on the fingerprint sensor". How I can solve this?. Sorry for my English.

The fingerprint data located at persist partition, you need to flash persist.img via fastboot command, and persist partition is only editable in EDL mode.
I had mi 5s, and I could only boot into EDL mode by a 9008 test point method.
