My phone got encrypted then wiped - General Questions and Answers

Hello,
Yesterday my Samsung Xcover 4 got wiped by "accident" (I believe it was a software bug).
Let me describe the case.
I have a Xcover 4 with original Nougat android (no root, no modifications at all).
I had only a pin lock - without encryption (it is important).
Yesterday I had a USB router option on, and was surfing web (yt etc).
Then I've lost internet connection and noticed that my phone hang. After couple seconds it rebooted.
When it boot up I saw a message "Phone is locked for security reasons, please input unlocking phrase".
Now this is a moment I've freaked out, but decided to put my regular PIN for screen lock.
I saw message "Checking" for like 15-20 seconds and then phone rebooted.
During boot instead of Samsung logo I got a "Removing" text.
And at this point all of my data was wiped.
Anybody has any idea what went wrong?
I lost all my photos, messages for no reason. It was ****ty day ;/
I assure you it was only 1 PIN try (and it was my proper screen lock code).
As phone is not rooted (+ FRP) therefore I'm not able to recover wiped data.

PIN+Swiftkey= locked+Floating Toucher=overiding security=weirdest xperience

hi
yesterday i had faced very weird problem with nexus 5 (rooted with CF-Auto root).. it got locked on me.
What happened was i installed swiftkey on my nexus 5. I had to go out and battery was low so I turned off mobile data and kept it for charging. I dont really lock my nexus when I am at home but whenever I go out I set up PIN for security and its been the same 4 digits number since my first android cell. So this time I went into settings=>Security and set it up. The only change was that instead of usual keyboard, swiftkey opened. So I inserted the number twice.. Nothing weird so far.. right ?...
Well, what happened after that was weird.. I couldnt unlock my nexus. No matter how many time I tried I couldnt unlock it. I can swear that I inserted my usual PIN but it wouldnt unlock. Then I started panicking. After few unsuccessful attempts the usual prompt came so I waited 30 secs and tried again. But no avail. So there was no option but to recover password via gmail, right ? well I wasnt that lucky.. I tried wrong pin for more than 50 times but "forgot password" prompt wouldnt come. (i hadnt taken nandroid backup for last 2 months so i started getting mini heart attacks ) then I tried 40-50 times more.. restarted my cell 3-4 times.. neither would it get locked not it would give me alternate method of unlocking.. thats stupid right ?? :silly:
I couldnt do anything. I checked online and found out that KITKAT DOESNT HAVE ALTERNATIVE OPTION of locking (or unlocking for that matter). Since my mobile data was off (I dont have wifi) I couldnt lock and unlock it using Android Device Manager (ADM) as well. So I was royally screwed ... and only apparent way out would entail data loss :crying:
I could just use camera and nothing else.
So I slept badly thinking that I would factory reset my nexus the next day. And in the morning it suddenly hit me :good:. I had also installed Floating Toucher app yesterday and I could see the floater even on my camera app. So I touched that.. opened quick launch and enabled mobile data. Then went on and locked my nexus using ADM and then I could unlock it with new password. phew...
so it was in all weirdest experience.
Now here are my findings
1) KitKat doesnt have alternative unlocking method
2) Nor does it lock your cell permanently. I mean you could try all permutations and combinations till you unlock it. (my ancient nokia would lock after few wrong tries..) and thats serious flow in system
3) Swiftkey may have screwed me over.
4) Floating Toucher (though proved as my saviour) could bypass system lock and thus one could use (or misuse) it.
Any thoughts on these people ??
Sorry for looooooong post
and sorry for toooooooo long post. I couldnt wrap it up without telling everything.

Locked out of Galaxy S7, can't afford to lose data on phone, need help now.

Hi,
Yesterday I set a fingerprint lock on my S7. It prompted me to enter a backup password and some other password, both with different requirements (one only had to be 4 letters, one was longer and had a number) and the longer one had to be confirmed whereas the shorter one did not. I set this up and tested it a few times, everything seemed to work great. Later I let my phone idle and it turned the screen off on its own for the first time, ever since then the phone has not been able to recognize my fingerprint. It doesn't even say "No match", it just acts like I'm not even putting a finger on it at all.
Tried over and over and eventually tried the backup password, which for some reason is the shorter one without a number. I put in what I am absolutely sure I put in, and it wouldn't take it. Tried a couple more times, even got so desperate as to emulate potential typing errors I might have made (since no confirmation for that password) and nothing worked.
Eventually I hit the timed lockout and I had to stop trying things then. So I went online and searched and discovered Google's Android Device Manager. I heard that if you lock the phone with it you can unlock it through the same manager and the phone will be unlocked. First thing that was odd was that ADM didn't give me an option to enter a password, just a contact message and phone number. I still put in a message and hit lock, and... nothing changed on ADM at all.
Now my phone shows the stupid message every time I wake it up and every few seconds on the lock screen (I can still attempt to unlock the phone with the password and use phone/camera though), but ADM doesn't even give an option to unlock, just change the locked message. I can't even get rid of the damn lock by changing it to blank. I heard Samsung offers a similar service but I never made a Samsung account and apparently one is required to use it.
Beyond that the only solution I've found is wiping the phone (which I can easily do, because there's an option in ADM for it which presumably works), which I really don't want to do since I have a lot of pictures and data on the phone that aren't backed up that I would absolutely hate to lose.
To make things worse it appears that this issue is specific to my phone/the S7/Samsung phones/something, as I have my old Nexus 4 listed in ADM as well and going through the options for it I see it has the ability to define a password, but no such thing for the S7. I really have no clue where to go from here, tons of googling hasn't found me any method I haven't already tried or can't do.
I'd be so grateful if someone here would at the very least find a way for me to recover data before wiping it to get rid of the lock.

HTC U11 : Your phone is encrypted message

Hi,
For some weird reason when i turned my HTC U11 on this time they show this message before start up:
Your phone is encrypted.
To ecrypt your phone, enter your lock spattern.
30 attempts reamin before device data is deleted.
No matter how many times i enter the right pattern it wouldn't accept it. I has just set the lock screen a couple of minutes before the phone got turned off. So when I check my phone on the linked google account it still says no lock pattern detected.
Now I am down to only 3 attempts and I do not want to lose my device data! Please help!!
Even USB Connection not working
I tried connecting the phone to my PC as well, but the device doesnt show up. Probably because the phone is not completely turned on yet ( i cant access anything on my phone

Data recovery from encrypted Nokia 6.1

TL;DR - Phone will not accept correct encrypt password. Need to dump data partition to computer and decrypt from there, or something like that.
So I have a Nokia 6.1 from 2018 that I used for just about a year. I upgraded to a nicer phone during summer 2019, at which point I transferred all the data I thought I needed, turned the power off, put the phone on a shelf and forgot about it for many months. I remember when I last powered it down, the battery was fully charged. Quite some time later I realized I needed to retrieve some important data written down in an old OneNote account that was synced with that phone and nothing else. Upon logging in, I discovered Microsoft had wiped the account clean due to an extended period of inactivity, meaning the only copy of that data now exists on that phone and nowhere else.
When I dug out the phone and tried to power it up, the battery was completely flat. I plugged it in and it booted up okay, but it would not accept the passphrase to unlock. I can only assume this is due to some sort of bug in Android (I believe it is running 9 Pie, but I don't remember for certain), as I know for a fact the password is correct. I've been putting off trying to unlock this thing for over a year now, but it needs to be done. I've noticed over my several attempts to enter the password that the phone has been behaving somewhat erratically. For example, it doesn't always respond to the power button right away. I'll try to press it again, and the screen will blink on and off several times. Also, when I first tried to unlock the phone, I could enter the passphrase as many times as I wanted, but now when I try, it locks me out for 30 seconds after each attempt, and also notifies me of the total number of failed attempts. When I reboot the phone, the failed attempt counter resets to zero.
Do I have any recourse here? Since I know the passphrase, is it possible to dump the encrypted data partition to my computer and decrypt it from there? The phone is not rooted, nor does it have any custom ROMs or anything like that. I appreciate any help anyone can give.
Quick addendum, I attempted to sideload the final OTA update sourced from the Nokia OTA Repository on Telegram onto the phone via recovery mode. It is running Android 10 now but still no luck unlocking. Interestingly, however, the failed attempt counter now appears to be working correctly, indicating I have entered the incorrect passphrase 31 times now. I'm not sure how many more times I can do that before it wipes everything.

Is my phone hopelessly locked or there's still second chance? (Forgot pattern, USB debugging on but not OEM unlock so can't flash)

So basically I have a Stock Sony Xperia Z3 Docomo variant (if I recall correctly it was D6653) that I used all the way from 2017, until I had to let it rest in 2020 because the screen was broken (although at that time before the screen went completely messed up, I managed to enable USB debugging in order to mirror the screen on my laptop with scrcpy so I can use it). It's just laying down on my desk cabinet for two years. Until finally I got a chance to replace the screen, the battery and the back cover earlier this weekend. Problem is, I already forgot the pattern to unlock it. Not even my brother (who used it sometimes to game back then) remember the pattern. Worse part is some of the SIM card, even when it does have data plan (I just simply put the SIM from my other phone), the phone is just going to show as full bar Roaming (R) and no internet at all so this phone completely have no network (although I do also have suspicion that data connection is probably disabled), and obviously that means I can't use google account to unlock it
Wanted to use TWRP or Aroma File Manager to delete the pattern lock file, but then I realized I have to flash this thing, and even if I do now understand how to install TWRP on my Z3 model because I already read various tutorial on this forum since Saturday, the problem is that OEM unlock isn't even enabled simply because at the time it was still a bit functional, I don't see it as something I need as I don't root any phone that I use. And as additional note, as time goes on obviously all of the laptop at home had gone many clean reinstall, which means no ADB key backup, and I can't authorize because pattern lock
Is there hope left, or this phone is completely locked?
(TLDR: Phone locked because I forgot lock pattern, no Internet, data stuck at R, no connection so I can't recover with google account, USB Debugging on but not OEM unlock)
