Fingerprint option missing on Stock Nougat.

Fingerprint option is missing on Stock N . Anyway to bring it back ? Hard reset doesn't help. Only on the first boot after reset I get the "add fp" in settings suggestions but it simply doesn't work. But no Fp option under security. Please help

Just in case someone will eventually face the same issue: solution is to flash again firmware : http://support.planetcom.co.uk/index.php/Android_Flashing_Guide
I thought that it was not going to admit the process of flashing in this status , but it does.

Unable to register fingerprint on Global coming from CN ROM

I flashed my RM5 with the CN ROM shortly after receiving the phone due to the software limitations of the NA ROM shipped on the device. With the CN ROM I successfully used face unlock. Now after flashing to the newly released global (v3.11) I get an error when trying to register my fingerprint (attached).
Steps taken:
1. Re-flashed CN ROM and attempted to register fingerprint and got the same error
2. Re-installed the new global v3.11
3. Flashed global recovery, boot, splash, parameter, then wiped data & cache. Factory reset. Still get the same error
Interesting to note that upon setup the phone said the fingerprint sensor was on the back.

You need to lock the bootloader to make it work, this will wipe your phone however. It says the fingerprint is on the back because the devs didn't bother fixing the typo in the setup.

Same thing after BL unlock/wipe. Same thing after BL relock/wipe
Are you sure you're using the correct command? There's "fastboot oem nubia_lock NUBIA_NX659J" and "fastboot flashing lock".
"fastboot flashing unlock" breaks the fingerprint

Yup I'm using "fast boot flashing (un)lock". I've unlocked and relocked now.

Have you tried "fastboot flashing relock"
relock not lock

Yes, it only accepts "fastboot flashing lock".
In any event, no matter if I unlock/relock the bootloader on the CN Rom or switch to the global ROM and do the same the fingerprint error persists. I even installed TWRP again and formatted data and did everything all over again.
Looks like I'm stuck with either face unlock only on CN or no fingerprint on global.
Really appreciate all the help though!

We need @JerryYin to supply an unbrick tool. Sounds like a partition has been wiped permanently. Only an unbrick tool will reflash all proper partitions.

No, the unbrick tool won't help. you need re-calibration the fingerprint sensor.

With nubia

For now you have to send the phone back to service center to perform the fingerprint recalibration.
I thought it's software issue not hardware issue , yesterday I checked my friend rooted phone it was work excellent but when I updated it and rooted again it want work again
@JerryYin
Currently I'm getting the "Loss of fingerprint calibration data" message when I try to add a fingerprint. This advises me to contact Nubia's after-sales service via the number "4007006600". This device is provided to me directly by Nubia engineers.
I've just tried to run the calibration and have gotten two errors - one being that the number of bad pixels is abnormal (even though the results are below the threshold), and the other being an "Unknown Error" message

Hi @JerryYin, The bootloader is locked (never unlocked). The device was sent directly by Nubia Engineering, so I can't send it back (no purchase receipt etc).
The issue seems to be that the device never passes the "CALBRATE_CHECKBOX" test, though everything else passes. If you could provide some insight into what this test is checking, I can finish calibrating it myself

Can someone help me, I need better clarification on some things.
So the first set of steps involve:
1) 'call' *#9959* and turn off the 'performance'
2) click 'start' and leave to phone/screen alone aka no touching it whats so ever, then I get the following text in image 1.
Now the steps after that have me confused on some things:
Step 2
3) Click 'Next' and the screen will dim abit
Do I have to leave the screen alone or do I have to put my finger immediately after hitting 'next'?
Cause I saw posts about leaving it alone and others saying to put my finger(thumb).
If I put my finger on the screen it gives me an error '0x3A self-exposure abnormal' (as in image 2);
but if I leave it alone it'll give me 'Auto_Exposure' & 'Flesh' tests succeeded (image 3)
I NEED clarification here, am I doing this part wrong by not having my finger on the Fp scanner.
Now for step 3, I have to:
4) click on 'Next' and the phone will do the 'Dark' and 'Dark-Base' tests. The should be left alone here as well. (Image 4)
I need to be in a dark room for this, correct?
Now for the final step
6) Click 'Next' and put my finger back to the screen on the blue FP scanner(?)
When I do this; I end up with '0x14 the number of bad pixels....' (image 5)
Any help is very up appreciated.

Reboot to miui recovery by holding volume up and power button and Wipe data in it. It will delete everything on the phone but may solve the issue.

That was first that i did. Doesn't help
There's no way to workaround a locked bootloader except edl mode with authorized account.
