Lock screen bug - Xiaomi Black Shark 2 Questions & Answers

Just incase anyone else gets it, had a frustrating bug where after using the phone as normal throughout the day, I just went to unlock the phone using the to fingerprint unlock, which it said was unavailable and to use pin to unlock.
Upon inputting the pin it refused to accept the pin, was deffo correct used the same pin for years and years, no way I was getting it incorrect. No matter how many attempts it wouldn't work.
In the lock menu even holding down power I was unable to open the restart or turn off phone options aswell to compond the frustration.
After holding the power button for what felt like forever the phone performed a restart, the phone was able to be unlocked using the pin after the restart.
Had the phone for weeks and this is the 1 and only time it's occured. Just thought I would mention incase it happens to someone else

I can confirm that behavior and also the solution. Had that once as well.

Nearly the same issue here but in my case the power menu to restart the phone "normally" worked.....

***Need help ** *Device was locked - any idea how to open

My device has been working perfectly till suddenly & without any early notice the device has been locked with some kind of locking.
After reset the device goes into the locked status showed in the pictures, no option to do hard reset,
Tried all options, seems like one of the keys is defective and that’s why can’t perform hard reset.
The device is locked and the 90 minutes limit don’t go down, you can’t do anything.
However if there is a incoming call, you see it on the screen and you can answer the call.
Does anyone familiar with this lock screen ? how do i pass it & relase the device? please advise & help me ....
This is the password protection built into all versions of windows CE. (accesed form control panel/personal/security (or something like that, may vary with OS versions). It has options to lock the device after switching it off (going to sleep mode is considered switching off too), or after the device is not used for a given period of time. The whole point of this protection is to prevent unauthorized access to the device, so i think that without the password you're screwed
Did someone play with your phone before that happened? Maybe it was a "joke" by one of your friends? If you never set the password, anyone can enter the password settings applet and enable it. That's why it's always a good idea to set the password, even if you don't plan to use it -it is also required to enter security settings...
So, if you really want to HR, first of all make sure that one of the buttons is really defective - I just checked and you can't turn off the device by holding the power button when it's loched - this might be your problem. So try holding the comm manager and voice command buttons and press reset button on the side (keep the side buttons pressed until you get the "reset to factory defaults" question)
.
If that doesn't work, try checking if the device connects to activesync when it's locked. It shouldn't happen, since it would be a possible security hole, but knowing microsoft...
If it does you might try to flash its ROM (of course you would lose all your data).
And if it does not and one of the buttons really is defective you might have to disassemble the device in order to do a HR (by shorting the switches' contacts with some metal object), but i wouldn't do this if you don't have some experience with electronics, since you might damage the phone if it's not handled properly with case removed. It might be easier to go to a GSM repair shop and have the switch replaced.

Forget all that password bs. Lock your device with this rogram. Unlock by pressing both soft keys at the same time.

Help! Locked out of Tytn

Can anyone help me get into my phone? For some reason it is no longer accepting the 4 digit password when I switch on the phone. It's not saying the number is wrong, just "Emergency phone calls can be made". It says this as soon as any numbers are entered and before the Unlock soft button is pressed. Pressing the Unlock button seems to do nothing.
I can still browse the phone using ActiveSync. Is there a file I can remove to prevent the phone from locking when I soft reset it?
I've got HTC home installed and the phone is running Windows 6 (an official O2 upgrade). I'd like to avoid hard resetting the phone if poss.
Thanks
Fixed
Tried the same 4 digit pin today and it worked! There must be a timed lock that kicks in after a number of tries. There was a clock running yesterday on the screen.
But the odd thing was that I hadn't tried to get into the phone for a couple of days.
Now a bit worried that this'll happen again randomly. Does anyone know how this works?

HTC HD2 Unlock problems

Hi,
I have owned my HTC HD2 for about 3 months now. I have had a problem since i first got it which is really bugging me. Sometimes when the phone locks, i am unable to unlock it with the slider. The slider gets to about half way across the screen and then freezes. If i leave it for a few minutes it goes back to a locked position agian and when i attempt to slide the slider across, it freezes.
The only thing which gives me access to my phone again is to perform a hard reset by removing the battery.
Any ideas? The phone is on UK Vodafone and is running the latest firmware (v.1.72)

I don't have an answer, its likely to be sense trying to load something and hanging.there are loads of threads about unlock problems, all different, however I wanted to help you avoid confusion by pointing out that removing the battery is a soft reset, not a hard reset.
I'd start by removing some apps, see if it changes the behavior, then re add til it happens
i've the same issue. but not removing battery, just press little red restard button uder battery cover. i think it happens when i enable rotation of today screen or because of proximatelyscreenoff program bug. after removing today from rotation of bsd tweek i have 1-2 restarts for 2 weeks.
I had the same thing sometimes, but never happened with the latest rom I am using, and I am pretty much installing the same apps over and over after each flash...
You aren't by chance running the facebook application?
Leaving that open and locking your phone will result in you not being able to unlock your phone
I wonder if this problem has anything to do with power supply; I sometimes can't unlock the screen either and a few moments ago my battery had run out and when putting it on AC I wasn't able to unlock it. When it had charged a bit there were no problems unlocking it.

HD2 screen unlock probblem
Hi All,
I have put my screen unlock code as 0000 and set as 5 mins to lock the phone.
But that is becoming a headache now.
Sometime the phone behaves very unusual, it doesn't takes my code "0000", no option rather to reset the phone or remove battery and restart.
After the reset the phone works with my code (0000) but don't know when the same problem starts again.
Need Help..
Anyone solved this problem?
In the Att Tilt2 the power button was on Top & could close the Screen while talking on the phone
How do we do that in the HD2 cos its Off button is on the Red Call Shut button
Anyone

HD2 Hard Locked
Okay...so maybe Facebook is locking my HD2. It's LOCKED I'm recharging, I've attemted a soft restart, hard restart and every other restart out there...nothing is working. I even tried pushing the white button below the battery case and holding the volume up and down...I actually thought that it began to do a hard restart. It did begin but then it got stuck at the "swipe" demo. It is definitely stuck.
HELP!!!!

402sh sharp hard reset how?

Hello,
I have a problem with my "sharp softbank aquos 402SH
I setup a pattern lock. Since I have not used the phone for some time I cannot remember the pattern anymore.
I thought an unlock with a hard reset is no problem. But I found no way to boot into recovery mode(tried power and minus button, power and plus button to boot).
Also the device did not show up in adb as a device(Windows 8/Sharp USB driver installed) but was recognized as a storage device.
The user manual says:
"Do not forget pattern, Lock No. passcode or password set for canceling Screen lock(write it down if necessary). If you forget it, visit the nearest SoftBank Shop for recovery procedure."
As I live in Sudan and there are only softbank stores in Japan. So this is not possible for me.
Is there any other way to hard reset the device?
same prob

Are you sure? Have you tried power-cycling the device? (Let it discharge all the way, and charge it all the way.)

Hi there

i forget the password pattern
custom cable data with R jumper to ID pin with zadig software cannot flash the twrp
could someone help me out of this
thx
i also have that kind problem also show to many people but no way found of any to recover my bally please do something
As I think this phone did not get that many updates this might still work. I remember early on back then that i somehow managed to make a pattern that I had not meant to so could not unlock. Also quickly found out I could not get into the bootloader. But I found out you could bypass the lockscreen if you went into the emergency call screen. The thing is, you'd have to make a call then you could use the drop down notifications and enter settings app or something like that. I can't remember clearly, but I could atleast get access. And from there i just disabled the pattern. Don't feel I can recommend this though as it depends on how quick you are, and police services are sort of being misused this way. I remember being frazzled and extremely annoyed at that point as I had only had the phone for a couple of days. Ended up spamming a call three or four times to the cops to bypass without connecting a call. They called me back wondering what the deal was ? oops.

PIN changed on its own!! HELP!

Hi there!
My OP6T was working fine 24 hours ago. All day yesterday I was unlocking with fingerprint and/or PIN. The phone died, I plugged it in and went to bed.
I woke up today and turned the phone on. It asked for my PIN due to restart, I entered my PIN and got wrong PIN. I thought I mis-clicked, so I tried it again. Still says wrong PIN. I restarted the phone and tried again, still said wrong PIN.
I thought I was going crazy, I did NOT change my PIN nor did anyone else (I live alone). I tried entering into recovery but theres password protection, which I don't remember encrypting my phone ever. I am using this phone fully stock, no custom recovery or unlocked bootloader. It is my business phone and I cannot afford to factory reset it!
I searched online and found many posts on OP forums of people having the same issue. For most of them, the phone changed its PIN from a PIN on another app such as MS teams, Business Outlook or work profile. I do not have any of those apps nor did I install anything else recently.
I am losing my mind here, please help me get into my phone. I have had the same PIN for 3 years and I enter it more than 20 times per day!
I can think of two options:
1.- someone else knows your pin and changed it without you noticing (doesn't matter if you live alone)
2.- you have memorised the pin with muscle memory and the pin you think is the correct is not but you don't realize because you've been using muscle memory. Been there, after 1 year of using the same pin couldn't remember it because muscle memory
Neither of those things is the case here. I urge you to do some research as this is quite common. Many, many threads over at OP forums of this happening to people especially after an update.
Someone would have had to break into my house while I slept ,took my phone off the charger, turn it on, change the PIN, turn it off and then leave my house.
Or somebody would have to remotely access my phone while it was off, turn it on (?????) Change the pin, then turn it off.
And no this is not a muscle memory issue. My PIN is my PIN, I did not forget it or change it.
Something is up, usually if you enter the PIN wrong the device is supposed to lock you out for 60 seconds, then more and more. Here, after 2-3 wrong tries I get told I have 2 more chances, then 1, then nothing. Then I enter 2 more times, it will repeat "you have 2 chances" I use those chances up and nothing happens
