Fingerprint option is missing - LeEco Le Max 2 Questions & Answers

Hello,
i bought a used x820 with stock rom 18s. The option to add a fingerprint in the menue was already missing. Flashed it to Cuoco 23sv93b but still no changes. Is there a workaround to get it back?
I can choose to add it, but in the sub menue "screen lock" there are only passsword options and the pattern.

Maybe the fingerprint is dead. That is why it was sold as 2nd hand?

In order to be able to unlock using your fingerprint, you must first choose a backup unlock method (pin, password or pattern), in case the fingerprint is not recognized or the sensor (as many of us are experiencing) fails. Are you sure it's not that?

Forgotten pattern unlock, fingerprint works

I can unlock my phone OK with my fingerprint, but I can't remember my pattern unlock (well, I think I can, but the phone doesn't accept it). I need the pattern to modify the fingerprint unlock, e.g. to add more fingers. Anyone know how to reset the pattern when fingerprint is working OK?
I'm on stock .253.

Well This Is Very Easy To Fix .
Follow The Steps:
1) Identify the Gmail registered with the device.
2) Check whether "Android Device Manager" is enabled in Settings-> Security -> Device Administrators if not enabled ,then enable it .
3) Login to Device Manager

Thanks. I think this would have worked, or I could have used myxperia.sonymobile.com similarly. Unfortunately I rebooted the phone, and it turns out, even with fingerprint enabled, that it needs a pattern to unlock the first time after rebooting! I had to wipe it with Xperia Companion (there seems to be no on-device recovery user interface that we can use), which was annoying.
I've now set it up again and made very sure I knew the pattern before adding fingerprints!

Messed up fingerprint scanner by restoring TWRP backup from another phone

So first I installed CM13 + gapps to a new honor 5x phone and it went pretty well until I restored my backup from TWRP (which from another device)
first the issue was my lock screen is giving me incorrect pins. deleted something in the system/data and bypassed it.
then I cannot use my fingerprint scanner (but the pin for lockscreen works now) it shows four fingerprints enrolled (which was mine in the twrp backup) but it says "fingerprint hardware not available" on the lockscreen
so i deleted something in the system / data / user.db which removed the 4 enrolled fingerprint: https://forum.xda-developers.com/honor-5x/how-to/fingerprint-issue-restoring-twrp-backup-t3435170
but now i cannot register the fingerprint. decided to just revert to my stock backup (emui)
and now the fingerprint setting is missing. it appears in the search menu, but whenever I input my pin to register a fingerprint id, it just goes backs to the screenlock settings menu pls haaalp meee
update:
tried reverting back to stock rom by flashing boot.img and system.img from an update.zip (extracted)
was able to use fingerprint scanner again but when I install CM13 (without restoring my backup)
it wont let me get past the set up lock screen password.
whenever I enter my pin, and confirm pin, it wont let me click next. tried skipping it in the setup wizard and went to the lock screen settings and it still wont let me click next after confirming my new pin

Fingerprint / Pin

My LOS 15.1 hasn't locked - no Pin, no Pattern.
So I would like to add fingerprint to have some security. But it works only together with a pin/pattern - at least I understand it like that.
So I give it a pin, added fingerprint.
Now I have a problem. While the device is still not asking for pin/fingerprint when open it - it asks when I want to change something in these security settings. But my dammned pin fails. I am 100% sure I used that one.
What can I do? Beside that I can't change security settings it seem I have full access.
And isn't it possible to unlock the device with just the fingerprint?
I could found a few answers by myself.
Don't know why my pin number fails, I reflash a backup and it was clean again.
The fingerprint just replaces a pattern/pin, that's why this is combined. Operating with just a fingerprint is not intended for some reasons.

Is pocophone encrypted by default?

Hi there..
I'm trying ti understand device encryption before i install a custom ROM on my poco. (Any links explaining how encryption works on android would be greatly appreciated)
My first question is whether the pocophone encryption is turned on by default.
Under the encryption settings, the "encrypt device using lock screen password" slider is set to off.
However, every time I reboot the phone, i am forced to enter the lock screen password as fingerprint and facial recognition do not work. I assumed that this is because encryption had been enabled on my phone by default. But then why is the slider set to off?

The option that you are talking about under encryption settings, is the same as "Android secure start up" on AOSP. If you enable this option, you need to enter your device password while you restart the phone. Or else your device won't even boot up (and you won't see the lockscreen) completely and you will be stuck. It's an extra layer of security on top of lockscreen password/pattern/pin. Now coming to your second question, it's a security feature on android where no other unlock methods will work except PIN/Password/Pattern after you restart the device everytime. And it has nothing to do with encryption or decryption. Even if you decrypt the ROM, you will still have to enter your password or pin or pattern on every reboot. Only then all other unlock methods will start working. Some ROMs have a feature where you can bypass this security and unlock the device straight away on every reboot without entering the default pin or password/pattern. But they also put a disclaimer that it's not safe.
Thanks for the info.. But one of the questions "Is the Pocophone F1" encrypted by default?" is not yet answered. I am very interested to know. And (while I am asking) if not, "How can I do encrypt it"?
Yes, it is encrypted by default.

Rooted MUIU 11, Reverting to stock, boot pin still active

Hi - I have a Poco F1 running 11.0.9 with MUIU EU and Magisk 25.1. I'd like to remove the pin check at boot so that I can sell the device (I don't want to deal with locking the bootloader again). Is there a way to remove the pin? Under Developer Options, I see the "Encrypt device using Lock screen password" is disabled. Do I need to enable/disable it, or..?
Any suggestions are appreciated! This is a great device I just don't play pogo anymore
SOLVED: enable-then-disable did the trick.
