To Start android, enter your PIN after reboot ?! - Lenovo P2 Questions & Answers

Hi,
This morning i took my phone off the charger as usual. And i thought i had not rebooted my device in a while (i do that from time to time and never had an issue) but now, my device showed a page where it says "start android enter your pin right pin".
This is already weird because i never set a pin but i set a pattern. I tried some pins that might be it but all were wrong. Then i googled it and found that android device manager can do this because of suspicious activity (?!?). I also found that i had to enter the PIN that simulates the pattern i entered.
This does not help/work either. Once or twice i got the message "to continue turn your phone off and back on" but that just brings be back to entering the pin.
Normally after a reboot, i have to enter my sim PIN first and then enter my set Pattern and everything works like normal.
How can i fix this WITHOUT erasing the device?
EDIT: I am not rooted nor do i have any custom rom. It's all original.

HTC M8 pattern password not accepted or resetting.

Somehow my password pattern is suddenly not detectable and it shows as wrong password. As there is no more option in lollipop for "forgot password" and using the gmail account to log in. How do I reset the password on a HTC M8 without doing a reset? I've tried logging into the google account, and I can use the "find" option in the device manager to locate the device, but if i press the "lock" button and try to enter a new password, for a split second it says "We have sent a lock request to the device", but then it says "Since Google has verified that a screen lock is already set, the password you entered won't be needed." Wtf is going on? I am stuck with a pattern locked phone of whose password i know but the phone doesnt detect it anymore. Is there another way to reset the password?
No replies?
Well.......
Let me start by saying that this is a delicate matter, what if the device is stolen and somebody wants to get the info or device to work without wiping it. I know that this is probably not your intention and that it is hard to prove otherwise. But the possibility could be there in the worst case scenario !
Now don't get the above personal, it's written from another point of view, as i am running HTC phones for the past 6 years and never encountered this all of a sudden at any point. So from my point of view i find it difficult to believe.
To get to your point ...... not sure if it can be done otherwise but to reset the device. Depends if it's rooted or not for instance ?
Cheers

According to the story, looks like either : 3rd party apps are interfering (can also be malware/virus) OR someone physically got hold of the device and changed the password(perhaps he thinks its his own)
Try restarting the device while holding the volume up button only, android will go into safe mode and disable all 3rd party apps. If the password still doesn't work, then you have 2 options:
1) if S-ON : factory reset and lose all user data
2) if S-OFF or bootloader unlocked: remove password (this is the most details I can give without being an accomplice)

[Q] Help, I can't unlock my screen

I haven't used my nexus in a couple months, turned it on today and there's a PIN lock.
I don't remember ever setting this up, I tried my usual PINs and none work.
I keep trying but I never get a forgot password log in with google option. I always get 5 wrong entries, wait 30 secs.
I'm at 35 incorrect PINs so far.
-I've also tried going to device manager but my device is always unavailable so I can't send a lock screen to it.
-I can't do a factory reset because my recovery is broken and I can't get into it to erase my data.
-I can't flash a new recovery because my computer isn't a trusted device to access it and I can't allow it because I can't log in.
I'm not sure what else to do.
I have a secondary user on it but I can't turn on the developer options for it because it's not the primary account.
Any ideas what I can do?
If you can get your driver issues figured out, so that the Fast Boot driver works, you can just reflash images from the Bootloader. You do not need to get into Recovery, or get passed the pin lock to reflash. To make it easy, you can use something like Wug's NRT and use the "Bricked Device" option to flash images from the bootloader screen.

Restart Issue "Android is upgrading..." Everytime I reboot my device

The message "Android is upgrading..." always show up every time I reboot the device.
This happens to me too but it's very strange because it seems a pattern lock I had entered persists across factory resets. So now I have to enter both my old pattern and then my new PIN to unlock my phone when I boot up.
The pattern lock comes up after the "android is upgrading" box which also flashes "starting apps" then "finishing boot" and this is after the boot animation. After I enter my pattern, it goes to boot animation again, then loads Oxygen OS 3.2.1. The reason I find this strange is because after the factory reset, I used a pin number at the setup instead of a pattern to lock the phone.
Why is my old pattern still there? I don't like the delay caused by android is upgrading and repeated boot animation.
As a note, I originally used adb sideload to upgrade from 3.1.3 to 3.2.1..
I think I figured it out. First I tried this method: http://www.androidexplained.com/oneplus-3-fix-twrp-restore-unlock-bug/
But that didn't work... I realized that this was a device encryption thing because TWRP was asking for my pattern as well; not my new pin.
So I restarted into bootloader, connected to PC and used fastboot format userdata. This actually wiped out the encryption and now when I turn on the phone it doesn't say "Android is upgrading", "Finishing boot..." Nor does it ask me to enter my pattern. This did of course reset the phone so it looked like a first-run screen where I followed through and set up a PIN. It seems fastboot format userdata is more complete than a TWRP factory reset.
However, at this time it looks like my OnePlus 3 is un-encrypted and I have the option to encrypt it now. See attached screenshots. The question is, what will happen after I encrypt the OP3? Will it have an annoying looped boot animation and a request for my PIN or pattern?

After you boot up after encryption go in security there should be an option to require pattern to start device, if that's disabled you won't have the double boot animation. As far as "Android is upgrading" on every boot, that usually happens if you add an app to system partition. I have Google dialer and GSam root companion so I get two apps upgrading on boot.
Your pin or password will survive factory reset.

Stop rebooting the device then lol

"Android upgrading" message on 3.2.7

I noticed that when I enable "PIN on boot" in security settings (when setting a PIN, it gives you the option to require the pin to boot - to my understanding it's hiding the decryption key for /data in another boot image, which then decrypts the key and hands over the boot process) I can briefly see a "Android is upgrading" message before I can enter the PIN.
It does not take long, it just does this on every boot. Note this is for the decryption only, it's not for the "regular" Android lockscreen that comes later.
I was wondering if there's anything wrong with this, or if it's just like this. It's not a major annoyance.
Maybe someone else on 3.2.7 can check and let me know.
Thanks!
I'm having the same thing here on 3.2.7 but never really wondered why tbh
I used to see that but I removed the "pin on boot" option as it is just annoying as it means the phone stops in the bootup process and you have to manually continue it. If you turn that off then the phone still requires a pin entry instead of fingerprint to unlock the first time after booting.
That's true. But it means your system is still much easier to break into. When Android has fully booted, the data partition has already been decrypted. Pin on boot (to my knowledge) unlocks the partition only after the pin has been set.

Nexus 5X stuck in loop - password required after device restarts

Posting from following original reference:
https://productforums.google.com/forum/#!topic/nexus/yMUh6a2SVLs;context-place=forum/nexus
I've had a Nexus 5x for a couple of years and recall accepting an Android update about a week ago, since which time I've restarted my phone several times. Unfortunately, I can't tell you the Android version because I'm currently unable to get past my lock screen.
Yesterday I restarted my phone and went through the steps of password => Android loading => fingerprint to unlock screen, but I also received the message "password required after device restarts" so I entered my password again. I know the password is correct because it works initially (to start Android) and because if I type anything different, it tells me that the password is wrong. However, each time I enter the correct password, the screen goes black for a second (which it would normally do when unlocking the screen) but then it returns to the "password required after device restarts" prompt.
I've tried powering off, restarting and 'hard' restarting by pressing down the power button, but the result is the same each time I reach the step to unlock the screen.
I can see alerts (eg, emails, whatsapp messages) and I receive visual/audio notification of calls/messages, etc. but I can't access the content.
My last backup was about four weeks ago before I began international travel. There are important data on my phone that I need to get access to hence following questions:
1) Since the password is still valid is there a way one can Remote Desktop into the phone and retrieve the data?
2) Any other way to get into the phone?
Any help in this matter is highly appreciated.
Thanks and Happy new year 2018.
