Device PIN - Xiaomi Mi Mix 2 Questions & Answers

Hi,
I use NitrogenOS and I want to go back Los15.1. I installed, and the start screen ask pin code. I thought lockscreen pis asked, but not yet, because after asked the lockscreen pin code. Now, cannot start Los or other rom, because asked Device Pin COde (message: re-enter device pic code to continue). But I dont now what is device pin code. I tried wipe everything in TWRP, but did not help, so I cannot use new rom. I have a complete twrp backup previous rom, and that is working. How can delete or re-add device id, and where?
Thanks,

When I restore twrp backup working now, but if I want to set the lockscreen pin, it will also ask for the device id

SOLVED: under TWRP delete lockscreen.db following path /data/system

lockscreen fingerprint and backup password problem

I was trying new roms this weekend. I did a full backup of my current rom. I tried 3 roms But decided to go back to my backup this evening.
I successfully completed the restore. Rebooted the phone and tried to swipe my thumb on the home button to unlock my phone as I usually do. It didn't work. Tried again and again. Finally entered my backup password and it unlocked my phone.
I figured I would simply go into lock screen settings and redo my fingerprint. NOPE. When I try to access the lockscreen secure options it tells me to swipe my fingerprint. My fingerprint doesn't work so I just tried to enter my backup password and it tells me wrong password. WTF!
So I can unlock my phone with backup password but when I use backup password to try to change security settings it tells me my password is incorrect.
OK, so i got it. here is how:
I deleted this: /data/validity/template.db (using root explorer) "Thanks freeza"
flashed this: LockScreen_Security_bypassV1.1.zip from this link: http://forum.xda-developers.com/note...d-pin-t2948336 "thanks dr.ketan"
Flashed this: registry.zip from page 4 post 36 from same link as above. "Thanks dr.ketan"
Rebooted phone and re-did fingerprint and it worked.

[Q] TWRP Restore makes PIN error

I had this problem with all TWRP versions for this device:
When I completely restore all partitions with TWRP and I boot up it gives "Wrong PIN" but the PIN is right. Also tried 1234, 123456, 0000 and 000000. Cache/Dalvik format does not do anything.
Nothing works, so I'm not able to use my lovely P2 now...
Anyone can help me?
Sorry should have googled it:
Firstly you need to boot into TWRP and then follow these steps:
Go to Advanced > File Manager > data > system.
And then delete locksettings.db, gatekeeper.password.key and gatekeeper.pattern.key.
HOW TO FIX
------------------------
Simply boot into TWRP and enter your PIN (if you've set one) to decrypt the stroage. If you don't have TWRP (for whatever reason) you can do so via ADB too but ONLY if you've connected your phone to your PC beforehand and also accepted it's fingerprint on the phone itself.
Delete (or rename) the following files inside /data/system (note that probably not all of them exist for you, simply delete those you can find):
password.key
pattern.key
locksettings.db-wal
locksettings.db-shm
locksettings.db
Reboot the phone and (if you've set a PIN) enter it to decrypt the storage one more time. After that you can simply unlock your phone with a swipe.
Go into Settings > Security and set your preferred unlock method again, Android will ask you if you want to set a boot-time code too. Select whatever you want here, it's a nice security addition but can be annoying sometimes.
Enjoy your phone again!
^This. I was having a similar problem not able to unlock the phone after installing other rom via the dual boot app.

After doing this screen lock is by passed but later not able to set new pin. Settings app crashing.
Thanks for this info but I too had this problem yesterday and after 2 hours trying to figure it out had to flash the rom from scratch. Hopefully it can be fixed.

Thanks a lot.
I keep this zip on my phone and flash it after every TWRP recovery.
It deletes needed files automatically.

Thank you, just fixed my Zenfone 3 Laser pin error after twrp restore just by deleting these 3 files. Went back to settings and set another pin, restart, test, all good without errors. Much appreciated

My OP3 says wrong passwd on boot, but in twrp same decrypt passwd works... Help!?!

Ok so i have a OnePlus 3 and it has an apparent glitch, im running a custom ROM, (shouldnt have anything to do with it... I would think) and whenever i try booting my phone it keeps asking for my encryption password, and so I enter in the password, and it keeps saying wrong password...
now when i boot into my recovery, it will ask me for the encryption password, and so i enter the same exact password again, and it successfully decrypts my data, it works.
now why would that work in recovery and not for the bootup sequence...?
I tried using my lockscreen PIN, the decryption password, the default decryption password, and still keeps giving me wrong password.
Android 7.1.2
PureNexus Rom
OnePlus 3
please help, thanks
Follow this and it should sort it out
In twrp, head to Advanced > File Manager, and go to the /data/system folder. Scroll down and find the two files with the .key extension. Delete both of them (by tapping on the file and then tapping the “Delete” button). Then, delete all the files containing the word locksettings.
So on my Nexus 5X, for example, I deleted the following files:
password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal'
Try this.
nope didnt work back to same screen on boot
however i can take screenshots... LOL
Had same thing today but twrp was also not accepting my password so did a full wipe ,lpst all my data and not not using any lockscreen and fp because of fear of this happening again , i think magisk ask this if i flash su per su i will not get these things
Did you try the default password of password?
go to twrp and open file mangaer - data - system - delete locksettings.db and reboot
yep tried the defaults, did not work :*(
this didnt work for me
Factory Reset in TWRP (format data) should work.
I could only fix this by wiping the entire phone. FYI, entering the wrong password numerous times did not automatically wipe the phone. Instead it told me I had -5 (etc.) tries remaining. I never found out why exactly this whole thing happened.
If I had this problem try to format everything and reinstall. Before Backing Up
Always make nandroid backup after removing Secuirty and ensure that storage is un-encrypted for maximum ease.
I had the same thing, you or someone else must have encrypted your phone. When i encrypted my phone i never had the option to choose a password, so the next time i tryied getting into recovery it would ask me for a encryption password (which i never knew). Anws the only way to remove this was by full clean wipe and flash a new rom. P.S always backup before doing anything ?

Magisk and encryption

I installed RessurectionRemix and i followed the process i will describe now:
I was on 8.7.5 developer.
Flash MIUI from Mi Flash Tool just click on option Clean All, Let it flash and boot up, after it boots reboot to fastboot since you did only clean all it'll not relock BL.
Then flash twrp in fastboot. Go to wipe> advance> select everything (data, system, cache, dalvik, internal, vendor) everything. And swipe right.
Now keep in mind do not touch the format data option at all.
Now go to reboot menu and reboot to recovery after it boots back to recovery transfer the ROM and other files, flash and reboot system and you'll have 100% encrypted device.
Flash the rom
Flash gapps
After that process everything worked fine and the phone was encrypted. Almost instantly (5-10secs) after I power the phone it asked for password.
But i installed magisk through TWRP and since then it asks for password when the phone boots completely and asks the password just to unlock the lockscreen.
Inside settings it says phone is encrypted but my guess is, that it isn't encrypted.
How can i fix that? What is wrong in the process i followed? What is the correct process?
Thank you!
I guess those steps were for lineage os. For others, you've to format data to disable encryption.
i want to have encryption enabled.
I dont want encryption disabled.
What are you asking exactly?
If you go to
Settings - Security & Privacy - Encryption & Credentials - Under Encryption
Are you been offered the choice to encrypt phone? If your not then it is already encrypted.
Is it requesting a password to boot and also to unlock the device?
If you need password to boot, then you selected that as an option when setting up password.
Can be removed by changing your password to swipe/none and setup your password again.
If TWRP, can not decrypt the device, make sure your using the latest.
Why didn't you post your query in RR thread?

I didnt post in RR because, i tried Aospextended and the same thing happened.
Thank you very much for the solution you gave!! I disabled screen lock,re-enable it with password and now it asks for passwoed on boot and on TWRP.
Thank you again!

pin password required after reboot

Just unlocked my bootloader and flashed a ROM. Every time I reboot the phone it will ask you for a password first before it can boot.
I searched it on google and said its a data encryption for new android versions
Is there any way to decrypt o to remove the password everyboot?
You enabled that when setting up your pin/password.
Change it back to none or swipe and setup your password again, and make sure required on boot is not selected!
You basically enabled encryption. Go into your custom recovery -> formate data. I recommend flashing Magisk (so you disable forced encryption & dm verity) or you can flash lazy flasher (search it on github or google).
If you do so your device gets formatted as well
Also, make sure to backup everything before formatting because everything will be deleted.
