Hello, I have the same problem as well. Did you know the problem solver or anyone who solves the problem.

 

[muhsinkara]

I have the same problem with this friend. I have installed rom with fastboot. I have uploaded it unfortunately.persist.img is negative.

how you get fix that?
my Mi 10 Ultra same Problem with Fingerprint, maybe Tommorrow send back to china about that, maybe cant fix that

 

[muhsinkara]

I wonder if there is no persist.img file to correct fingerprints

I have a Mi Note 10 Lite - dont know if the problem occurs because of the same source but:

I discovered, that ALL OF MY sensors do not work anymore, because of the unlocking-process (bootloader unlock) - after this, pretty much every sensor doesnt work anymore - maybe, just maybe, your problem (with the nonfunctional fingerprint-sensor is an issue that happened because of the boatloader-unlock?)

Kind regards,
Cosmo

I mean if the bootloader lock is off. Does the inoperative fingerprint sensor fix

Actually my hypothesis will state the opposite: Whenthe bootloader is unlocked, the sensors could probably set inactive.
If you relock the bootloader MAYBE that could be fixed, but I cant tell - just do not know.

And be careful if you relock your bootloader - there are some "tutorials"out on youtube, if you follow them, you will definitelly
brick your cellphone (you can unbrick it, but probably you need a person with a certified account). So better be careful, if you
are not fully sure about that.

And at the end, its just a thesis.. maybe I am wrong and it has nothing to do with the unlocking of the bootloader - in my
case it seems it was the reason why all my sensors "act numb", which looks to me like they went inactive for some reasons
(probably because of the bootloader unlock, before unlocking - they worked well).

I totally agree with what you said. I hope it will be fine if there is a new updated persist.img.

I totally agree with what you said. I hope it will be fine if there is a new updated persist.img.

You know, what I am currently doing? I download the global-image for my Mi NOTE 10 Lite and I want to extract the persist.img and flash it via twrp.
Lets see what it does.. if the sensors will work and do their job again, I let you know - then you might have to extract the persist.img for your pro-version
and also try out if it could work. Lets see!

 

[muhsinkara]

I did it with the persist.img flash method with twrp. There was no change. The persist.img file was taken one by one from the global rom eea rom chine rom fasboot roms, they were all negative.

 

[Cosmo_Dookie]

Did it - didnt make a difference. Now I flashed a clean new version of MIUI 12 (global) also didnt do a difference.

 

[muhsinkara]

There is no master who knows the solution to the problem.

 

[Cosmo_Dookie]

Today, I am gonna try to flash a completely new image on my phone - low-level-format - everything new - and lets see if things will work out..

Even more - I am looking for a straight android-only-OS-image that runs on my Xiaomi (no IMUI) - but currently I didnt find anything available for MiNote10 LITE..

Yeah, should the clean reflash(probably of the custom-europe-version) work out and I am available to use my sensors as it is supposed to, I let you know, maybe a clean reflash can work out - then the persist.img should also be clean, but lets see!

 

[muhsinkara]

The only solution to this problem is a persist.img file containing all current sensors.

 

[Cosmo_Dookie]

I believe so, yes!

 

[Cosmo_Dookie]

Its strange.. I flashed a new MIUI-12-EU-img and after the flash-process/install-process it states:

Failed to mount "/persist" (invalid argument)

So it seems the persist.img cant be mounted and cant be installed - does anyone have a clou?

 

[muhsinkara]

Hello I did some research, it is said that 10 pro fingerprint problem will be fixed with eng rom. Where can we find mi 10 pro eng rom.

 

[sandozer]

My old Redmi Note 5 worked instantly on fingerprint learn.
Mi Mi10T Lite took me several minutes, could not get thumb to work, but on perseverance forefinger did.
Kept having to move the whole finger over the sensor time and time again, could see the map building slowly.
So, persevere it is doable !

Im now having the same problem on my mi10, i flashed the persist .img from the global rom which mine came with to fix the cts issue.

But now my fingerprint wont work. Ive even flashed the entire system back to factory and locked bootloader still wont work.
