Question about Goodix Fingerprint

[DeckerSU]

Do you have working Goodix Fingerprint on CM builded on this tree? Now i'm have a device with MT6755 CPU and same fingerprint and have a little problem. Seems all blobs and sepolicy are fine, if launch any app to test finger - seems it works, vibrate and read finger. But i can't add any fingers through standart Settings menu. It crashes:

Seems this happens in com.android.settings/.fingerprint.FingerprintEnrollEnrolling. Before i add finger :( In your build it works?

Same here. We had to restore the enrolled fingerprint data from stock.. I'll look into this and report back

I think i get a solution ... but need some time to test. Fingers now enrolls correctly and added to base. But seems there is some problem, it doesn't recognize at lock screen. I will write here after some tests about a solution. BTW, where is enroleed fingerprint data is located on stock? I found an XML /data/system/users/0/settings_global.xml with fingers ID, but there is other data located?

check this video, you can just mute it if you don't understand Hindi.
the process it till 19.00 to make the backup file for fingerprint data stored with stock

Heh ... more troubles coming ... fingers really stored in /data/app/mcRegistry/TbStorage, but here another trouble. PackageManager in Lineage see that /data/app/mcRegistry doesn't contain base apk and killing that folder:

03-08 22:34:34.110   633   633 W PackageManager: Destroying /data/app/mcRegistry due to: android.content.pm.PackageParser$PackageParserException: Missing base APK in /data/app/mcRegistry

Seems need to patch PackageManager in Lineage too ... working ... after i complete all - will post a solution.
