lock screen security not working - Xiaomi Mi A1 Questions & Answers

I cant use fingerprint or any other security method. I'm on stock Jan pie. I restored this via twrp backup because I can't get aex 6.3 to work. How can I get fingerprint, of any other method to work?
When I setup a pin. The screen is still swipe to unlock.

I didn't had same problem but I actually rooted my phone and then unrooted it , but after that my phone could not update to next security update ... I tried many things but what worked for me is..
There is YouTube video from Technobuzznet
And it has the link of twrp flashable stock rom https://drive.google.com/uc?id=10HXyZ_68KAQqWn46DamlUKH9dgH2ZFZ0&export=download
Just wipe everything and flash this rom from twrp

Trouble with booting after rooting, help.

Hello everyone, I went to root my phone today, I used a Youtube tutorial with the exact links/downloads given. Followed the steps but my device is having trouble rebooting, it is just stuck on the Samsung logo flashing and I'm not too sure what to do. Also when it boots up I get the error message in the top left of my screen saying "Recovery Is Not Seandroid Enforcing", hopefully that helps.
Thanks.

Hard to help if you do not write in detail. Such as phone type, links you have used, etc etc

You need to flash SuperSU manually.
1. Flash TWRP
2. Format data
3. Flash SR3-SuperSU-v2.79-SR3-20170114223742.zip
http://download.chainfire.eu/1021/SuperSU/SR3-SuperSU-v2.79-SR3-20170114223742.zip
You simply brick your phone. You need to know that there is not Chainfire-AUTO-Root for Nougat, so you need first flash Stock FIRMWARE from Sammobile, then flash TWRP and flash SuperSU
Or you can flash many of 100 roms with prerooted supersu and busybox.
Hi there,
After upgrading my S7 Edge G935F to stock version xxu1dqd7 (with latest May 2017 upgrades) I had to install TWRP (twrp-3.1.1-0-hero2lte.img) again.
Unfortunately this change will NOT recognise my pattern lock now! I had to re-install the stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) using the HOME_CSC file to hold my data.
This re-installation brought me back to the game, but without TWRP and hope for root, but the pattern pin (the same) is now working...
Update 1
Installing TWRP (twrp-3.1.1-0-hero2lte.img) over the new stock image (DBT-G935FXXU1DQEF-20170523093738 with ODIN) without having the pattern lock enabled feature during start will result in stuck on
the samsung title.
Update 2
I had to repeat the step above (stock firmware), so stay now without root.
Will check later with other stock versions
>It seems you didn't format the data partition or dm-verity was not installed. Happened to me, won't boot if >anything is altered like when installing a custom recovery.
Yes, I did it with and without dm-verity, All 3 options,
TWRP (ok, but pattern lock will not recognized)
TWRP + supersu (2.82) (stuck on the samsung logo)
TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo)
Yes, I didn'T format the data partition. Didn't want to lose my data ( Never had a problem to upgrade stock roms on my old S4 and root after).
Before the stock upgrade, I run with the Jan 2017 patch level (I bought this 2 days ago) and was able to root with the above method.
Today I wanted to jump the the latest stock version but run in trouble then.
Update 3
Downgrading to Stockrom from 2017-Jan-30 Germany 7 G935FXXU1DQB3 G935FDBT1DQA8 is not an option (anymore), The system boot up but with lot of errors and it's unresponsable and not usable.
Upgade then to the April patch status (2017-Apr-17 Germany 7 G935FXXU1DQD7 G935FDBT1DQD1) brought me back to operational,
but TWRP + supersu (2.82) + dm-verity (stuck on the samsung logo).
Will try it now with the Februar patch version
Downgrade to the Feb patch status (2017-Feb-23 Germany 7 G935FXXU1DQBX G935FOXJ1DQB2) had the same resut like the Jan version - not usable.
I'll give up now and install the April version without TWRP.
I need root to restore my apps AND data with Titanium Pro.

With the TWRP + supersu root method, no matter what 7.0 stock ROM you use, you will not succeed before you disable boot pin and format data. You can restore data after rooting.
So start with the latest stock ROM that is working 100% for you, flash twrp, format data, flash supersu, and it should work. You have to format data because root and stock rom currently does not work with encryption.
Or even simpler, use the new cf autoroot, however it seems you still have to format data.
I had high hopes that the new cf autoroot nougat binary would work with encryption, but alas it seems it doesnt, at least I had the same wrong pin code at boot issue as with twrp. I havent had time to test it, nor to format data and root, so I am currently not rooted.

Thank you doclorenzo.
I had success with the latest stock version (xxu1dqd7) and your recomendation to format data in TWRP.
In short: Boot in Download mode, Install TWRP via Odin, Boot into TWRP - format data, supersu (2.82) + dm-verity
and then restore all data. Unfortunately it requires lot of time (at least 4 hrs to restore the apps + more for fine tuning)
Thank you and hope to have a better way with the next stock update and TWRP

Fingerprint stopped working

I need some help
1. I was on Oreo 8.0 May security patch and I wanted to update via OTA, when I tried to Restore Images through Magisk and Uninstall Magisk couldn't find Images backup. So I flashed boot.img and WIFI stopped working. I tried Persist Ressurrection Tool but it didn't fix wifi issue.
2. I flashed stock 8.0 may security patch with MiFlash. Wifi works again. Updated to August patch via OTA. Rooted. After a Reboot, System UI stopped working.
3. Flashed stock 8.0 may security patch back, always cleaning data. Everything was fine, but fingerprint stopped working.
4. Flashed stock 8.0 may security patch again, saving user data this time, but for no reason all data wiped...
5. Fingerprint still not working =/
What can I do?
When i change to a Guest or new user, fingerprint works.
Tried Wiping Cache and no results
EDIT---------
Uninstalled Magisk, Updated to August patch OTA. Fingerprint working now...

1+5 Home button doesn't work after recovery and OTA failed.

1. H2OS 3.5.0, BL unlocked., rooted by magisk. It worked fine for 1 year. Today, I tried to updated magisk from 17.1 to 18.0, after reboot, it stucks at startup.
I have to use TWRP to do a recovery. But after that, the "Home" never works again.
2. There is a OTA update: H2OS 5.1.2, but the update always failed.
I tried do official recovery by flashing stock-recovery.img. Then I tried OTA update again, it still failed.
3. I tried lock BL again, but after that it can't boot. I have to unlock BL again.
Anyone can help?
> Is it just the fingerprint scanner?
> Have you tried disabling lockscreen security? If not, try setting it to 'None'), reboot your phone, and try to register your fingerprints again.
> What happens when you use the onscreen navbar?
Last resort: did you backup your data? I suggest wiping completely and flashing the latest official ROM (link: https://forum.xda-developers.com/oneplus-5/how-to/official-oxygenos-4-5-2-7-1-1-ota-t3627003 , use the full zip).

How to setup official MIUI without breeaking OTA updates or fingerprint sensor

Due to the use of encryption by the official MIUI ROM we cannot use a custom recovery. Only the MIUI stock recovery knows the encryption password so only it can install OTA updates. If you are also having issues related to the fingerprint scanner data disappearing after each reboot, they will be fix by this.
So the actual solution... This might not be obvious to everyone but due the encryption password being unknown we actually need to keep the stock recovery. That's it. Just install the stock recovery. Now you might ask how you flash things like Magisk since the stock recovery doesn't support that kind of thing. It's simple too, just you a ciustom recovery. You don't actually need to have a recovery flashed to use it, you can just boot a image via fastboot(1). This is a bit annoying but still way less annoying than not being able to install updated or the fingerprint data resetting every reboot.
(1) Boot to custom recovery without replacing the stock recovery
Code:
fastboot boot custom-recovery.img
hmmm, I am not really sure what you wanted to explain, however, not only the miui stock recovery knows to handle encryption, as the ATG's twrp with certain version does it fine, as well.
They do but only the stock one knows the password used to encrypt MIUI.
PBRP handles OTA updates without issue. Have had two updates since installing it and haven't had any problems.

[Root]My fingerprint stopped working after root

I rooted using the standard process, unlock bootloader, flash twrp img, flash twrp zip, flash magisk zip. But now my fingerprints register but don't work when trying to unlock. Anyone else with same problems, or a solution to this one?
I'm sorry I solved it myself. It was due to my matte screen guard. It worked perfect after removing it.
