Hi - I have a Poco F1 running 11.0.9 with MUIU EU and Magisk 25.1. I'd like to remove the pin check at boot so that I can sell the device (I don't want to deal with locking the bootloader again). Is there a way to remove the pin? Under Developer Options, I see the "Encrypt device using Lock screen password" is disabled. Do I need to enable/disable it, or..?
Any suggestions are appreciated! This is a great device I just don't play pogo anymore
SOLVED: enable-then-disable did the trick.

Hello Gentlemen and Gentlewomen,
Well, I have a ZE554KL, with OREO 8.1 installed.
The phone is boot loader unlocked.
I use the fingerprint + pattern lock.
I know it is my fault, but I got the phone running for 2 months w/o rebooting, so all of suden, today the phone locks itself and ask for the pattern lock for "additional security". Well, after 2 months not using the pattern, just the fingerprint, I ended up forgetting it.
Now I am stuck. I cannot reset the unlock method neither via the phone nor the google device page. Is there anyway to remove the pattern lock or switch back to the fingerprint, without the need of wiping my data?
All the best.
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.
Hello,
I don't have any encryption issue, I'm asking for the sake of curiosity about FDE in general on Android 9 and MIUI.
I have a POCO F1 since like 1 year now. It was like MIUI 8 or something when I got it.
I unlocked it and rooted it. No problem.
The way I proceed to root is: I inject TWRP from a PC during the boot recovery, and then I flash Magisk.
That way I have a clean, untouched stock POCO F1. I just flash root. No custom ROM.
That's all I need.
Now recently, I switched to MIUI 11 with the latest F1 update. All is fine.
And then I discovered that there was a (new?) option to encrypt the phone with a Lockscreen password.
That's nice as this something I did on my previous phones so I was happy this see this option on the F1.
So I activated it, set my lock screen creds, and ... and that was it.
It was instant. Done in 1 second.
--> Here's the question: How is activating lock screen encryption instantaneous?
Here is what I understand so far:
there is a default FDE on the POCO, so the phone has always been encryption from the start
FDE works with a private key, which does the actual encryption
This FDE private key is locked behind a master password
The master password is known on a default POCO install without setting lock screen "ecnryption"
So what happened when I activated lock screen "encryption" option was to simply change the master FDE password with mine.
Disc encryption has actually not changed. Nothing was re-ecnrypted
The actual FDE private key is still the same
So... this means the actual data on the phone is still encrypted with the same previous private key
Are all my assumptions correct?
If yes, then I'm left with the ultimate question:
Does the actual private encryption key is unique per POCO F1 phone? Or is it a known one like the master default password?
Thanks!
Hi
My Issue: Unexpected Bootloader lock by Xiaomi ADBFastbootTools while using Custom Rom (Xiaomi.EU) & Rooted Phone (Redmi K20)
My Phone: Redmi K20
TWRP Version: LR team TWRP 1109 for K20
I clean installed Xiaomi.EU stable rom ver. V11.0.2.0.QFJCNXM_v11-10.
Phone was rooted by using default feature provided in LR team TWRP recoevery. (magisk v20.0).
(If it helps, it shows in advanced settings of Magisk App, Preserve Force Encryption: ON, Preserve AVB 2.0/dm-verity: Off.)
I opened Xiaomi ADBFastbootTools and connected by phone. Developer Options was not enabled and thus USB debugging neither. So at that state of phone connected, I enabled those features. The phone popped confirmation for allowing the PC. I pressed ok and immediately right after, the phone bootloader was locked. It was updated on Xiaomi ADBFastbootTools. To confirm, I checked on the phone. Indeed it was locked. In developer settings, Allow OEM Unlocking option is there and turned on. However, It does not have the option of "Check Unlock Status" in developer mode anymore. So I can't add the device either for further unlocking.
My Xiaomi account is logged in and was also logged in when this happened.
What can be in this situation?
Can I even do a reboot? Or the phone will be bricked?
Is there a way I can unlock the phone again?
The situation seems very bad to me.
Looking forward for your support.
Thanks
Hello, my device (Redmi Note 8T, MIUI 11) has recently stopped accepting the pattern lock I set up when I got it first and I'm trying to bypass the lock screen. The problem lies in that I haven't got USB debugging activated nor Google's Find My Device. I'm almost sure I haven't forgotten the pattern, but I've tried multiple patterns similar to the one I remember. Is there a way of unlocking the bootloader or booting into TWRP without having to access to the phone's settings? I've been thinking of flashing Aroma File Manager and remove the system's files for the lock from there but I haven't found how to do it without unlocking the bootloader. Is the only way of doing this restoring the phone completely? I'm almost a complete beginner in Android modding and I appreciate any extra help, thank you.
