Hey,

Tired of seeing this message when trying to enroll a fingerprint?

I have seen many people asking for fix and there has also been a file around here for the fix zip. But it was always hard to find that file so here it is.

Steps for fixing fingerprint:

Code:
1. Reboot to recovery
2. In the file manager, go to /persist/data/
3. Delete all the files named finger_0_x and finger_0_x.bak (finger_0_1, finger_0_1.bak,...)
4. Reboot and try again.

If it still doesn't work, flash the attachment zip in recovery.

This works wonders!!!

EDIT: Please notice that I am not the owner of the file!

sorry for reviving this old thread, but I have been digging around for solution for quite some time and can't really get to the bottom of this.
I am facing the exact same problem - after upgrade, did factory reset on stock 10 but did not remove fingerprints prior, and now enrolment simply fails each time. Files you listed above are not present inside /persist/data (using twrp file manager).
if I flash persist.img I am afraid that could kill my device since some are suggesting that there are device specific information on that partition...
any suggestions?

I've tried this method in the past when downgrading from GSI or Android 10 to Android 9 and it doesn't work (the above mentioned files are not present). What I do is flash Oreo OEM rom via EDL in MiFlash, then reboot to bootloader and flash the Oreo "persist.img". Then I flash Android 9 OEM rom via EDL in MiFlash (without flashing the Android 9 "persist.img"). This method always works for me.

go to file manager in twrp.

navigate to /data/system
1. delete the file locksettings.db

navigate to /data/system/user/0
1. delete everything inside the folder fpdata
2. delete settings_fingerprint.xml

now you can install persist fix zip.

This will remove any pattern lock/pin lock/password/fingerprint. leaving a slide lock when you boot.

did ANYONE actually manage to install persist fix from the first post in this thread WITHOUT losing data or having to have to factory reset?! thanks
