Z1 Pro fingerprint sensor not working

Samarang

That says it all really.  Fingerprint reader was fine until a few days ago, but now doesn't work at all.  

I see Fingerprint in the security menu, it lists the stored fingerprints and gives me the option to add new ones, but it doesn't seem to get any input from the sensor.  

So I can't use it to add new finger print and can't use it to unlock phone.  

No message, nothing.  Just like it's not there.

Have rebooted, but that makes no difference.

Anyone have any ideas?

Well that is always the easiest thing to say.  But it isn't the right answer.

Please use SPFT and flash complete ROM.
Here you have SPFT instruction

I came across similar issue in z1 when I was playing with firmwares and only SPFT helped. If firmware upgrade not help you need change to format + download.

You need perform factory reset (settings - backup and reset - factory data reset)

That's it?  Just reset the whole device?  Did it work?

Didn't need to do a reset.  Just uninstalled a couple of recent apps and voila!

Hello everybody!

My Z1 pro has a not working fingerprint, too. Plus the battery bar iss always on 100%.
So I did a reset and flashed the newest and an older version, both didn't change anything.
Can anyone help me with this?

Please use firmware upgrade option if still doesn't work then use format + download on SPFT. After that you need use SN writer to write IMEI numbers. Here is SN writer instruction

Thx for the answer.
I 've used SPFT with firmware upgrade and "format all + download" with SN writer. No problems here.
But every time with the same errors: fingerprint and battery bar not working
After "format all + download" i can choose fingerprint configuration, but sensor doesn't react. Then I went back and tried to find it again in configuration but its no longer available. Just the pattern, PIN, passwort.
I don't know if it helps:
MTK_Driver_Auto_Installer_SP_Drivers_20160804
ROM: 20170907_p15v57c2k_kw_u52a
SPFT: SP_Flash_Tool_v5.1728
SN_Writer_Tool_v1.1728

Any other ideas?
