PIN problem and Security Settings crash - Huawei P9 Lite Questions & Answers

Goodmorning everyone,
I am desperate. I have rooted on my Huawei P9 Lite device by following the guide for Android 7 with EMUI 5. Initially it seemed to have gone smoothly. Not without difficulty I unblocked the bootloader, installed the TWRP, the kernel and the SuperUser application.
However after installing the Elite Kernel for P9 Lite All Variants CxxB3xx With MagiskSU v10.1 by HassanMirza01, I did not accept the PIN when I restarted the device despite being the right one, preventing me from entering and doing any kind of operation. I did a search on the internet and learned to be a fairly frequent thing, so I deleted with TWRP the files "gatekeeper.password.key", "gatekeeper.pattern.key", "locksettings.db", "locksettings.db-shm", "locksettings.db-wal" from /data/system as indicated.
Indeed, I rebooted my device again and I did not ask for any PIN, so I could use the device, but when I set up a new PIN, it does not allow me to. If I try to register one, after entering the PIN for the second time as confirmation, it hangs for a few seconds and goes back to the screen lock selection still set to "None".
Same thing if I try to set the fingerprint: first asks me to create the PIN and then stays impaled at the same point.
Also from "Settings" if I try to go to "Advanced" ---> "Security" the app crashes. Same speech if I try to access the "Developer Options".
Please help me solve this problem without having to do another Factory Reset because I can no longer lose all the data again.
Many thanks in advance!

Security Challenge locks up sometimes

Like, I don't know if I'm the only one experiencing this issue. Whenever I do something with the system, boot back up, first prompt telling me to enter my password to continue the boot, works. However, when I hit the system, enter the lock screen, it sometimes ask me for another password just in case. This second time I enter the password, wrong. I had made sure that my password was right, nope, still locked out. I had to use "No Lock for Home 2" Xposed module to somehow get pass this freaking lock screen. Am I the only one experiencing this issue or did I do something wrong?
I have tried almost everything,
1) Try to set a new password via Android Device Manager (LOCKED STILL)
2) Going to Security -> Password -> Typing the password all over (LOCKED STILL)
3) Going to Security -> Switching lock type to none -> Setting password again (LOCKED STILL)
4) Going to Security -> Switching to PIN (FINALLY WORKED)
What's bizarre is that under the Security settings my password apparently works, just not on the lock screen.
I would honestly prefer password over PIN and this is driving me insane. Is there a way to wipe the security settings in TWRP safely? Last time I tried deleting gatekeeper.password.key under /data/system in TWRP File Manager, it worked but FC whenever I try to set a new password.
Try clearing credentials under security

Nope, still the same.

Swipe to unlock is greyed out.

Hi.
Ever since i had to flash the stock rom B574, i have been unable to use the swipe to unlock option. I have the other 3 (pattern, pin, password) but not the swipe.
"Disabled by administrator, encryption policy or credential storage."
Now, before you start screaming about clearing the credentials in the security settings, i have done so 5-6 times by now.
I do not have any VPN installed. No Ad blocker either. And i have not encrypted my SD card (the option to encrypt is grayed out so i am unable anyway.)
I have tried several things. Set up a pattern with a pin as backup, then enter the pattern incorrect 5 to cause the system to remove the pattern.. Or something. It didn't work. Checked everything related to administrator and disabled it.
I've used SD Maid to clear any temp or cached files/settings.
The only thing i haven't done is a full factory reset. But i really wish not to.
And as i am unable to remove the pin, i'm not able to flash TWRP or root .
Frustrating.
Edit: System info:
Model:ALE-L21
Buildnr: ALE-L21C432B574
I got the same issue and I posted this problem week ago. Still not solved.

OK. Good to know it's not just me.
I'll keep an eye out on your post as well.
Probably the only solution is factory reset

Funny thing is that i tried to perform a factory reset, but the phone only switched off and refused to start up again.
Only way to get it working was to connect the cable to computer and phone before starting it in fastboot. Then restart.
But the workaround is fine by me. (set a pattern, choose backup pin, enter the pattern incorrectly 5 times. Wait 30 seconds, enter pin and the lockscreen is gone.
I believe this must be a bug in 574 onward. Or a ridiculous security "patch"
I have B584 and had this problem. Method with incorrectly pattern doesn't work for me, but factory reset works.
This issue is present almost on all versions I guess. Funny thing is, even some Honor users have problem with it. But trick with a pattern password is working though.

Settings crashes / Uninstalling App runs reboot

Hi! I hope that someone could help me.
First some informations:
I have a Huawei P9 Lite, running B370 (VNS-L31C432) + patched SuperSU root + unlocked bootloader.
My Problems:
-If I try to open developer settings, security settings, ... I always get message that settings will be closed. I don't know how long this problem exist, because last time I tried to open was 2 weeks ago.
-If I try to uninstall apps, my phone starts a reboot. But not a normal reboot. It shows me boot animation and after it I am on desktop again, without beeing asked for sim pin again. I think it will be called "Fast reboot", right? But problem is, that App is still installed.
Would be nice if someone could help me, to fix these problems.
Greetings and sorry for bad English!

Why does my phone keep getting decrypted?

I'm very confused by the behavior of my Nexus6p right now. I would like my phone to be fully encrypted, IE, you pick up the phone and can access absolutely none of my data without typing in a password. So I've clean flashed it several times, usually whenever a new update comes out. And each time I do this, the phone behaves how I want, when it boots, I get a password screen that says "enter a password to continue boot". It goes on this way for a day or so usually, and then suddenly this password screen stops showing up and I get the "you must enter a password after restarting" screen that clearly has already decrypted my data because I can see notifications and even play music through bluetooth without entering the password.
After each clean flash, I have been installing various mods. This time around, I have the things I've flashed down to TWRP 3.1.0, Magisk 12, and ElementalX 4.08. In the security settings, the phone still reads as encrypted, so I'm very confused. Is this normal behavior for this device, or is it one of the above things I have flashed? Either way, how do I fix this so that my data actually stays encrypted when the phone boots?
I have had similar issues to fix I formated everything and then installed the rom installed newest vendor image and then kept on eye on what I allowed special access to my phone
Keeper was wanting special access so I stopped using them and switched to last pass I have not lost decryption on phone boot
Also decided to pay for esexplorer pro to get ride of any possible infected ads
Your phone data is still encrypted, but your security settings are not optimized for what you want to accomplish. Make sure your Lockscreen has a password/PIN/Gesture set. There is the password on BOOT when encrypted, a password on Lockscreen when the screen is off, and In Settings>>Notifications>>Gear Icon>>"On the lock screen"- there are three settings. Default is set to "Show ALL notification content". Set it to NOT show notifications for now until you set which ones you want to show or hide. TWRP and EX are not causing your issue. Magisk might be but I don't use it. Uninstall just to be sure and/or check in the dedicated Magisk thread. This is on the stock 7.1.2 ROM. If you are running a custom ROM, YMMV.
So if I understand the issue correctly, you clean flash and you have the prompt to enter your credentials before booting finishes. Eventually you get set up and upon a reboot you notice that the prompt is gone?
Check your apps. You're using an app that requires an accessibility service (see Settings / Accessibility / Services). Granting an app accessibility service will do away with the boot entry of your pin/pattern/password. Set up your apps again and either don't use the app in question or just don't grant it the accessibility service for whatever feature requires it.
Known issue, btw. I forget why it happens, Google may turn up the results you're looking for.
Edit: Despite it not asking for that prompt on boot, your phone is still encrypted, by the way. This also has absolutely nothing to do with TWRP, EX, Magisk or how you choose to have your notifications hidden on lock screen.
2nd: Sadly, just revoking the service won't usually restore the prompt while booting. You'll need to clean flash again and not grant it in the first place.
That makes sense, I was looking in the wrong place. That's a really irritating design decision, there's no sense in having the encryption at all if you're just going to store the material necessary to decrypt the data in the clear.
For now, changing my password seems to have returned the encryption prompt while leaving the accessibility services working to the best of my observation.
It will probably go away again shortly​, most likely after the app uses the accessibility service. If it does, revoke the service and change your password again or clean flash. I don't believe there is a way to keep both 100% of the time.

can't set any type of password/fingerprint P9 Lite Vodafone (C02)

Yesterday I've updated my phone using TWRP and something went wrong.
After the update I couldn't login, tough the password was correct and I decided to reset it.
I did a basic wipe then I rebooted my phone.
The problem is I can't set any type of password, I can't install apps from unknown sources, can't use emojis/uninstall apps without automatic rebooting(I mean wtf).
Is there a way to somehow restore my device? Maybe debranding it, flashing an older zip, idk.
EVERY TOUGHT IS MUCH APPRECIATED.
