Hello
Has anyone encountered this fingerprint reader problem?
I can't read the fingerprint!
Global Poco F2 Pro 6/128
ROM: lmi_eea_global_images_V12.0.3.0.QJKEUXM_20200923.0000.00_10.0_eea_e53e1f2537
Bootloader closed.
https://ibb.co/z6tymgq
I had great difficulty identifying the fingerprint and failed several times
Go to CIT , tap couple times on kernel to enter CIT test, in up right corner you have three dots, press on it to be able to enter advanced settings.
This is very important!!
You must enter advanced settings, and go to fingerprint options, you need black paper and white for test, when you finish it,you will get your fingerprint back.
Find my post, tou will see the same thread with this problem and how I solved it

Just go to advanced settings ,find three dots in right up corner and do fingerprint sensor test with white and black paper or something similar to this
I ran the CIT program 15 times.
I got this result:

I can remember on what Stock ROM I was ,because I have the same problem, and I was changing ROM from Chinese to India ROM, so after I found out for these advanced settings that solve my problem. I have luck , I was delete persist.img in TWRP that cause this problem with fingerprint sensor

Thanks for the reply!
Do you describe exactly how to do it?
I'm an amateur.
I can start if you describe exactly how to get started.
First to the menu using * # * # 6484 # * # *, then 3 dots on the top right and tools
The choice is the 12th fingerprint calibration
At first, the calibration is against a light surface, but a mirror is recommended (usually you attach it to a fingerprint reader). Then the calibration is against a dark surface. After that restart the phone.

I got a mistake here too!
I only have a problem with my right thumb but it is a problem with my finger and not with the sensor since with any other finger I know it immediately (LOL)
The only problem for me is not that it doesn’t solve it.
The problem is that I can't scan the fingerprint!
I only have a pin, pattern, and password option.

The phone is new, I tried it for the first time.
I tried several rom versions.
It was also a fastboot eu global rom, locked back.

You could try this:
save to Xiaomi cloud(if necessary)
Disable localization (on xiaomi cloud)
Remove security on screen lock
Factory reset

You said you tried several rom so you unlocked the bootloader?
I find it strange that when you bought it it was already in V12.0.3.0.QJKEUXM.
Are you sure that this is not a K30 pro modify to F2 pro?

If I remember correctly the V12.0.2.0.QJKEUXM Rom was on it when I bought it.
Here I opened and then put the EU.dev Rom system on it.
I tried the fingerprint reader on this first, but it didn’t go.
After that I tried a lot, but the mem still doesn't work.

That's good news that fp is working! Maybe you're right. However it's a sensor/hardware button, so maybe the button doesn't function while the sensor is working.
I hope it is software issue
All the best, buddy.

have you tried clearing the data and cache for Smart Key app? perhaps better to Force Stop the app, clean its data and cache then restart the phone.
He tried factory reset, which means data of smart key app have been cleared.
It's so hard to figure out what causes it
I doubt that, I didn't face this issue no matter what I've done.
I guess this leads to the possibility of hardware issue
Perhaps the final test would be to do a rollback to marshmallow rom, just in case. If that didn't work, service center it is then.
That's a great suggestions, I hope it turns out a software issue.

Strange. Are you actually pressing the button and not simply laying your finger on top?
Hello! My device wifi just stopped turning on, and I did reset networking config but that didn't solve the problem, so I reset It. Now I have a device with no networking at all, and now it's also locked because I didn't sign out of my xiaomi account. I wanted to unlock the device and try another rom to see if that solves the problem, but I can't do that since I need first activate the device.
About the device:
-No root
-No developer options enabled
-Wifi doesn't toggle on
-Sim card is not recognized (already tried other ones, in both slots)
-Xiaomi assistance doesn't want to help me at all (neither the seller btw)
I hope you guys could help me. I'm very frustrated because it's a recent new phone :c

By EDL, I mean a kind of brute force to flash ROM. Used mainly when hard bricked. As you don't have unlock permission you have to use this method to flash Factory ROM. You can find Instructions in YouTube videos for "Redmi Note 6 pro EDL flashing guide Test point method"

I've just bought a smartphone repair toolkit from Amazon, and I'm waiting for it because I don't have the needed tools to open the device and do the EDL by myself. It might get here around next week, and when done, I say if that worked.

I tried the EDL test points, but the device doesn't vibrate and turn on :c
EDIT: I was doing it wrong, I need firstly to connect the pins, and juts then connect the USB cable. I was doing the opposite hahaha
Windows Device Manager does recognize it, but Mi Flash still doesn't recognize the device on refresh, giving the error "length cannot be less than zero". I'm doing some search.

Actually, after flashing a new rom, after 12h the wifi issue returned, and I used this tool: https://www.xiaomitool.com/V2/
I used the option to flash an official rom, followed the app steps, and after the download finished, it couldn't be installed because of a bug So I repeated the steps, but instead of downloading again, i used the already downloaded rom (it is in the app installation folder). Then, success! Has been 2 days with no problem
About the auth itself, even by using EDL, after the reboot, I was prompted again by the mi account... So if you don't have the account, I'm afraid I can't help you... :c
I used this tutorial for the EDL: https://www.youtube.com/watch?v=7WfOprRVQww
Hello,
i did a transcript persist.img since then my fingerprint doesn't work. Unfortunately I did not make a backup backuppersist.img Please, if any of you here do not have persist.img functional or some other advice.
Thank you very much.

I tried Global and EEA doesn't work.
Flash to EEA ROM and then calibration it already works. Thanks a lot.

Probably you loose Widevine L1 also.
I lost my fingerprint too,find my thread about that and how to fix it.
There is no need to flash ROM.
Just go and tap couple times to kernel to open CIT test, ind the right corner go to additional setting and find fingerprint option,find something black ,paper ,white , to cover sensors.. follow instructions..its simple..and your fingerprint will be back
For me, the fingerprint calibration on the Xiaomi.eu ROM did not work. Because of this, I first made a flash on the EEA ROM and then calibrated the fingerprint.
I uploaded my backup. You can try it, maybe it will help.
I fix mine with calibration but did you try this one in advanced setting? In CIT?
Because if you not try this in advanced setting the first one will nor working..and you will not be able to fix it and pass

Also persis.img from other phone wont help ,for me didn't work.. only calibration

1.I have a rog phone 5 covert to tecentgame. When I move to version WW but then there is a fingerprint error (losing the system fingerprint authentication). Who can help me?
2.There is an opinion that restoring the system partition can fix the above situation, do not know if it is true or false?can anyone guide me on how to do the above?

It's a known issue. As of yet, it appears this is a drawback to the conversion.
I'm currently working on a solution to get fingerprint working after a conversion. I've located the error and a Magisk module should be able to fix it. I can't make any promises until that theory is fully tested, though.
Of course my Magisk install is broken and won't install from storage...
I need the system/vendor/etc/vendor_(something)_styles.xml
Started a thread for it, since those with a working reader are unlikely to be looking through this thread.

Unlocking BL and converting WW, there is a chance of losing your fingerprints, but back up the persist partition before conversion, you don’t have to worry about losing your fingerprints. Once you lose your fingerprints, you only need to restore the persist partition and your fingerprints will be normal. But it can only correspond to this phone, and restore on other phones is not possible.
