[FIX] Unlocked bootloader and Fingerprint Sensor Not Working

2021-01-03, 2:57 AM

So I spent some more time on this and here's what I've figured out:

- Fingerprint reader breaking while unlocking bootloader seems common with new phones

- Motorola Edge Plus uses Goodix fingerprint reader hardware

- There are two ways to fix this problem

        1. Restore gf_persist.so in /mnt/vendor/persist/goodix/ with a version before unlocking the bootloader

        2. Calibrate the fingerprint reader in Engineering Mode [removed]

HardReset.info: Engineering Mode
*#*#2486#*#*

 

 

Here's where I'm stuck:

- I do not have the version of gf_persist.so from before unlocking the bootloader. Perhaps, Motorola can help me with that file?

- In Engineering Mode, I tried various ways to "test" fingerprint reader and was unable to pass the test. Also, there is no option to "calibrate". If Motorola can share the calibration procedure then I might be able to sort it out.

 

Screenshots from Engineering Mode:

Finally, The Solution:

 

1. Take backup of  /mnt/vendor/persist/goodix/

2. Delete goodix folder

3. Delete all saved fingerprints, if any

4. Reboot

5. Enter  *#*#2486#*#* in dialer

6. Select CQA Menu Mode

7. Select Sensors -> After-Sales -> Fingerprint SPMT(Dual Rubber)

8. Start Test

9. Use White Paper under your thumb for FLESH FLAT

10. Cover entire screen with dark thick paper for BLACK FLAT

11. The test should pass. Go back to Sensors

12. Select G5GoodixSelfTest

13. Put your finger on sensor and you should get success

14. Select G5SPMT Test

15. Follow steps 9 and 10. For Last test, place your thumb directly on sensor. Test will fail.

16. Exit engineering mode and enroll fingerprints in maximum brightness

17. Enroll multiple entries for same finger

18. Keep locking and unlocking the phone and after few unlocks, sensor will work as new

Hi.

 

Not clear to me if you're saying the solution above works, or it doesn't.
