Bootloader unlocked = fingerprint unlock gone. Possible fix? - Realme 5 Pro Questions & Answers

Hi all
According to this article, unlocked bootloader = no more fingerprint unlock: "https://www.gizmochina.com/2019/11/28/realme-officially-bootloader-unlocks-every-smartphones-models-in-china/"
"For security reasons, Realme will disable the fingerprint unlock function to prevent privacy leak of fingerprint data on their independently encrypted fingerprint chip."
I've got AOSP rom on my Realme Q, and everything works great... except fingerprint unlock.
Anyone know of any potential fix for this?

base on my experience you need rooted devices to fix this, you need to pass cts profile. read MagiskHide Props Config to fix this

Its known bugs on AOSP based rom tree, but if you flash Lineage based rom tree, you can use the fingerprint for lock

Does this realy works?
All realme devices have the same problem, only the realme X not.
So how we can fix it?

My realme 5 pro is unlocked with root and magisk and fingerprint is fast like thunderbolt

Then please give us a tutorial on how to make the fingerprinter come to life after the bootloader unlock.
Thank you

Relocked Zenfone 6, lockscreen or fingerprint no longer working

I've had my Zenfone 6's bootloader unlocked for quite a while, but I relocked it a couple of days ago using the "fastboot oem asus back" command.
Everything went as expected and the phone did a reset. However, I can now not add any sort of lock to the screen.
Whenever I add a pattern, pin or password, the settings app crashes. Because I can't add one of these, I also cannot add fingerprint...
I've tried doing another factory reset without any luck and the phone seems to be working fine in all other ways...
Can anyone help?
Ask Asus team on ZenTalk. I haven't seen anything related in there. They should be able to clarify the issue.
Downgrade to pie and then let it upgrade to Q again. Fixed it for me when unlocking the bootloader. Something about locking/unlocking bootloader on Q breaks the fingerprint sensor but Pie doesn't have the issue.

Yes, what DaConcho said worked for me, trust him
Anyone in the US tried downgrading to pie using the firmware on Asus site?

Not working fingerprint reader & other things about unlocking the bootloader

Hi, ever since bootloader unlock in my Zenfone 6 fingerprint crashes all apps that use it (like Settings or OneTimeInit). Currently running pure stock. If I relock it with asus-back it returns to life, however I'd like to keep this state after unlock too. After second lock I've removed all phone security in case something blocked fp reader from there but no luck. Any ideas?
Also, is there any way to unlock the bootloader n-th time without using that apk unlocker/without internet conenction? I know the relock command but things that unlock it like asus-go don't work.
Probably downgrading to pie and then upgrading to Q will fix it according to https://forum.xda-developers.com/zenfone-6-2019/help/relocked-zenfone-6-lockscreen-t4033321
Oh, I will downgrade it to Pie allright. Just bricked my phone and messed up dm verity on locked bootloader. I prefer Samsungs to play with...
Edit: You were right. I've unlocked it on Pie and works great. I don't know why xda search couldn't find that thread for me. Thank you.

Will unlocking the bootloader kill the FP scanner?

I've had 2 android 10 Chinese phones now and both had the FP calibration lost after unlocking the bootloader.
The mi unlock software says doing do will cause loss of FP scanner functionality as well, so I'm afraid of doing so on my new phone. However, I'm not super thrilled with the camera after updating to MIUI 12 do I was hoping to install a global MIUI 11 ROM until they get it fixed
No "unlocking bootloader" does not break the FP. But if you do something after unlocking that breaks the FP, like messing with persist partition then it will break.
So my answer is: as long as you know what you are doing nothing will break

Ok that's a relief
Because it is becoming a real issue with Chinese phones

Question Google Pay (NFC feature) still works even if I unlock the bootloader and flash another ROM?

So, If I install another ROM can I still pay with NFC or its the to same with others phones that if you unlock the bootloader this function stops to work?

Maybe and maybe not. Look here as example:
https://forum.xda-developers.com/t/4267263/post-85119503
This question is relate to SafetyNet. If you can pass SafetyNet, you can have working NFC.
Pass SafetyNet on xiaomi.eu ROM
NOTE: These steps may no longer be necessary on latest xiaomi.eu builds. Check for SafetyNet status first (preferably with an app other than Magisk Manager). While the xiaomi.eu ROM for the X3 Pro is patched against bootloader status detection...

In all the comments no one knows if its works or not, may differ to one to another. I want to flash DotOS but Google Pay is essential and I want to be sure its works, sad!

You can relock bootloader with proper MIUI.
But even with unmodified MIUI, or even if you didn't unlock bootloader, you can still have faulty NFC. So you can't make sure, only try and error.
Life is just like this.

OP8 - FP sensor lost after locking bootloader

Hi,
I have OP8 and issue with fingerprint sensor not working after locking the bootloader. Issue started when i unlocked bootloader, rooted device - installed magisk with magisk hide module.
After that my banking app stopped working (even tho i had magisk hide). I need my banking app more than root so i decided to lock bootloader and back to stock OOS.
Of course i didnt DD my fp perisist image so i have nothing to work with. After stock rom installation i am unable to configure FP. It gaves me errors everytime i want to set a FP.
When i unlock bootloader FP is working like a charm. But i have to lock it for banking app to work. And then circle of life continues.
Unlocked bootloader - FP works - Bank app dont work(or GPAY) - Locked BL - FP dont work - Bank app works.....
Is there a chance to make a phone "like it is out of the box" ? no root, locked bootloader, etc?
