Messed up fingerprint scanner by restoring TWRP backup from another phone - Honor 5X Questions & Answers

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

Any way to backup my data and reset or to bypass PIN lock?

Hello!
A friend of mine, who owns a Samsung Galaxy S6 Edge, set her lockscreen up to pin lock, but forgot the pin code. So she gave me her phone to find a solution to
1. backup the internal storage (photos) without unlocking it, so we can wipe it afterwards via its recovery menu
or
2. bypass the lockscreen?? losing her installed apps and stuff is not a problem. She just wants her photos to be save.
Samsungs "Find my phone" is not working because she did not activate the needed options.
Any help is aprecciated.
Vulnerability where Samsung phones respond to USB when locked.
Or forgot pin reset with Google option from Lockscreen.
help ...
i have same problem.. a week ago my s6 edge has updated to marshmallow.. then 2 days ago another update.. i use fingerprint for unlock.. but after last update it said "use password for fingerprint safety" and there is no option for google account.. i dont remember my password. my phone locked for 3 days and i cant find any solution for unlock.. i dont want to lose any data because of this safety policy

thanks. my phone is s6 edge and hasnt sd card slot. so how can i download this file via TWRP to my phone?
can i download file with TWRP from my pc?
Download TWRP (3.0.0.x for 6.0.1 android) md5.tar extension and flash via Odin in AP section, make sure to turn off auto reboot, click start and should finish. Then hard turn off and turn on into recovery. You should be able to now use usb and transfer the .zip across to your device and install it, if not ADB push the file to storage

Can't unlock my Phone after update

Hi at all!
After yesterdays update over WiFi (don't know which exactly, but I think it's MiUI8 6.9.8) my Redmi Note 3 (Qualcomm, 32GB) wouldn't let me unlock the device neither with fingerprint nor pattern. Before I updated it was normally unlocking. Normally I use fingerprint, so at first I thought i forgot the pattern, but after several attempts the phone went into lock mode. I am 99% sure I know the right pattern, but it won't unlock.
I already read this guide: http://en.miui.com/thread-5684-1-1.html and tried this https://www.youtube.com/watch?v=NMAPEhH5z-8
But I have still several problems:
- USB debugging not enabled
- no recovery installed
- no root or open bootloader or anything like that
- no backup of all photos, which are on the phone itself and not on the SD card (I just came back from holidays)
- no cloud or similar backup
- Mi Pc Suite does not detect phone
- Google Device Manager states "Since Google has verified that a screen lock is already set, the password that you entered won't be needed." if I try the send a new lockscreen.
This method (with flash afterwards) could help me, I guess, but I still would loose everything: http://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
I have absolutely no idea how i can unlock my phone without loosing any data (especially the photos).
Please if anyone has an Idea, help me!
Same happened to me so I restored my backup, once the restore had finished I removed the finger print and pin number (I had read about this on the xiaomi Forum). Then did the update again and this time it was OK
sounds easy, how did you restore the backup?
Before restoring any backup, I suggest you hard restart your phone. long press the power button.
but if I make a Hard Reset I will loss everything on the phone.
Is there maybe a possibility to insert some sort of file or command via EDL mode, that USB debbuging will be enabled? http://forum.xda-developers.com/redmi-note-3/how-to/guide-reboot-to-edl-mode-fastboot-test-t3398718
No not the hard reset. I was talking about hard restart. The phone will just restart.
ahh I see, sorry my fault.
But nonetheless I din't made any backup ever with this phone.
same problem here
my phone redmi note 3(qualcomm 32gb) is also locked just yesterday ! it shows try again after 120 minutes and after the time completed it shows pattern and it will be locked again and shows the same dialouge after trying my correct password ! actually we shoud get forgot password option behind the emergency option ! please do give a reply to me if you find any solution it means a lot to me !
Well I am afraid I can't help you either... after searching for 2 days I found no solution and flashed my phone. so all data was lost...

Restored from TWRP backup, now lock screen pattern is wrong and I'm locked out

Basically as the title says. I restored from a backup in TWRP (tried the new MIUI build) but the lock screen pattern I had before is no longer working. What do I do?? I'm not totally locked out, I have my finger print saved so I can get into the phone, but I can't change or remove the pattern.
I had similar issue with password. Luckily fingerprint was still working. I had to do a fresh install.
REMEMBER: Before you back in TWRP, make sure you erase all passwords / pins / patterns / fingerprints that are related to the lockscreen/security of the ROM.
Get my le tomorrow but had the same issue on my Axon and there where 3 files in system/data called gatekeeper... and locksettings.db. When you delete this files in twrp the problem is gone

If you have Le Eco account you can reset your pin/pattern/password. I had the same situation just prior to posting this. My Le Eco account was created using my phone number and not mail id. I could disable the pin lock successfully by the following method.
Requirement: Working internet connection on the restored stock firmware.
If fingerprint is working then one can create a new working internet connection.
After 5 unsuccessful attempts tapped on forgot password. Another screen popped up requring me to enter password and showed the phone number against which my account with Le Eco was created earlier. Entered the existing password but was not accepted.
Logged in Le Eco account on PC. Used the same password which was not accepted by the phone.
Changed the account password - One can sign in via Le Eco website and click on "SHOP LEMALL" or LeMall website. Change region accordingly.
Had to wait for about 10 minutes as the changed password was not accepted by the phone immediately. Few times I got "login error" too as Le Eco site is notoriously slow and will time out. After few attempts the new password was accepted. The phone disabled my PIN and opened "Fingerprint & password" screen with Screen lock as "None".
I do not know if for those who have account with mail id as user name the phone asks to sign in by showing mail id instead of phone number as in my case.
Hope that helps.

Don't do backups with passwords/pins/patterns is the answer.

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.

soft bootloop after setting screenlock ( after dirty flash to Android 10 MIUI 11)

hi people, looking to your advice and suggestions.
I was on Android 9 Miui 10. Last night I did a dirty flash to Android 10 Miui 11. There was no issues during this process and the phone booted up fine with no loss of data.
Steps I took -
1) Disabled Magisk modules
2) Removed all screenlock and Google and MIUI accounts
3) Made a Nandroid backup before flashing
Today morning, I tried to set up screenlock on Android 10 MIUI 11. Added the pattern lock, and added a fingerprint. Strangely when I tried to add one more fingerprint (for my left index finger), it asked me to set pattern lock again. Well I set it again, and added the new fingerprint. Same thing happened when I set the face unlock. I added the pattern lock again. But, the patternlock never turned to ON status, even though fingerprint and facelock was showing ON.
When I tried to lock the screen and to test it out, I was able to unlock with swipe (with no pattern, fingerprint or face unlock required). I haven't set any smart unlock as well.. I thought perhaps a reboot will help, but now I'm stuck on a soft bootloop ( the phone boots upto to the lockscreen and reboots before I can do anything )
Is there any suggestions on what I can do ? Please advise. Thanks in advance

Fix
Managed to fix it my myself. FYI
1) Boot TWRP Recovery click Advanced> File Manager> data> system and delete 6 files (ref : https://forum.xda-developers.com/android/software-hacking/remove-lockscreen-recovery-t3530008)
1.access_control.key
2.access_control_password_type.key
3.locksettings.db
4.locksettings.db-shm
5.locksettings.db-wal
6./data/system/users/0/settings_fingerprint.xml
Bootup was successful
2) After bootup, you might find it difficult to set the screenlock password (won't take affect). Follow this -
In a web browser (on any device), log into Gmail with the account you used when setting up your phone.
Go to https://myaccount.google.com/intro/find-your-phone
Press "Lock your phone"
Enter "abcd"
Your phone's screen is now locked. Unlock it with "abcd"
You can now change your screen lock.

Hi there,
Good that you resolved on your own.
Also, this bug can be resolved this way. Try to setup second space. If you are already setup earlier with a password then follow the other member guide until the removal of locksettings db files. Then reboot and try setup the second space.. while setting up it will request to setup the password or pattern for first space and finger prints for second space. Once done move to first space and setup the fingerprints there for first space.
Just making a note here.. so somebody can make use of it in need at desperate hours...
I have spent sometime to figure this bug in the first space but setting up second space solved the bug.
Hope this helps.
Thanks.
