My kid changed lockscreen pin - OnePlus 6T Questions & Answers

Hello there, I'm using OnePlus 6t on OOS 10, somehow my kid changed the lockscreen pin and now forgot.
I've read multiple threads and asked a lot of people, but there seems no method to bypass the lockscreen pin.
I'd some important files which I couldn't backup/ not until my last backup.
Is there any way possible to recover my files after a hard reset as that's the only alternate i can think of without bypassing lockscreen without root.
FYI: Bootloader locked, currently locked, haven't hard reset yet, usb debugging off.

Nope, if you hard reset you lose everything. User storage is encrypted with a per-session key that is wiped when a reset occurs meaning everything on the phone becomes useless garbage the moment that key is lost. If you have adb enabled and have authorized your computer once before you might be able to pull files off using that but otherwise you might be screwed
The lock screen is designed to keep people out, wouldn't be much use if it let people exfiltrate data whenever they wanted

Don't even think you'll be able to get the pin off the phone. When you reset Google asks for the old pin used in the device.
If USB debugging is off, I don't even think you can flash stock firmware onto the device either.
You're pretty much screwed.

The best way to do is MSM tool. If you don't know the password your can't even get in to recovery mode( required password). By doing that all data will be gone.

[Q] Securing Nexus 4

Is there any way to secure android like ios7. In case if i loose my phone then no one can use it. Is it true a hard reset will remove my pattern or password? My phone is non rooted. Can someone install custom recovery too?

There is not fool poof way to prevent this. Even on IOS7 the security can be gotten around. Best advice is to make sure you are backing up your files.
Google does have a remote wipe option built into the Android OS. That is your best bet.
There is no full proof way to make render unusable, but you can call up your carrier and ask them to blacklist the IMEI so they can't use sim cards with it anymore.
You could however, protect your data. Do this by: encrypt your device, stock recovery, disable USB debugging, lock the bootloader. At least with this, if the device is stolen, if they don't know how to flash factory image, they'll need to enter the encrypted password to boot into the phone and can't copy over your datas.
You should also look up the app Cerberus, which with root can survive through factory reset (as long as they don't overwrite or format the "system" partition).

Phone locked out,

Hi there,
Friend of mine using Lenovo A6000+, Doesn't have google account in that phone. It was secured with the pattern lock. But unfortunately he forgot the unlock pattern. Since he have a lot of contacts in that phone, there is no way to reset it. Its full stock version. Just a basic user., so no root access or anything. In this scenario any other way to unlock the phone without doing a factory reset? The google answers are helpful only if the usb debugging is enabled. Since it is not rooted and basically a very common user used that phone, i don't think usb debugging is enabled. Any help appreciated.
By the way, i'm also thinking of flashing a custom recovery into the phone. Will that be of any help? Would it cause the phone to lose data? Will that need usb debugging enabled to do it?

I dont think, there's anything you can do about it. Ask him first, if he had ever connected to pc and authorized it for usb debugging. Otherwise, the only option left is to factory reset.
Edit: Brother, I'm working on something to change the pattern, which obviously I'll tell you. I'll make a flashable zip which you can flash through twrp. Lets see how this goes.
I'm not sure, if I'll be able to do it. But if it does, it would be very helpful for everyone.
:silly:
Edit 2: Finally I got it working!!! hurray!!
Just flash this zip below and the next time your phone boots, you can enter any "more than 3-dot" pattern and the phone will accept. Later, you can set new pattern or anything.
:angel: :silly:
P.S. I used CWM recovery on stock KK to flash it. Don't know why but I couldn't manage to flash twrp. Who cares anyway, if our job gets done. :silly:

Xiaomi Mi A1 stolen

Hi Guys,
my MOthers new Xiaomi MI A1 was stolen this week.
1. Now my Question, is it possible for the Thief to get on her Data?
Theroretically not, because the phone was on last official android update 7.1.1 (nov sec patch)
Phone was saved with a Fingerprint and PIN and ohone was encrypted.
2. Is it possible for the Thief to hard reset the phone via adb or fastboot to got a use for the phone (resell etc)
Thanks
Even if he would format it, the phone will ask to log into Google account of the user that was logged in before formatting. I doubt the thief is smart enough to bypass it.
1. did you enable "require pin/password for phone startup"? If yes, there is probably no way to decrypt the data without the PIN. If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP.
2. factory reset will trigger FRP, but it's probably quite easy to bypass it with a bit of patience.

Yes PIN was set on startup.
" If no, thief could unlock the bootloader (Xiaomi is the only phone I know which doesn't perform factory reset for this action) and use the default encryption password to mount the data partition in TWRP. "
How can he unlock the bootloader? I think he need DEV options and OEM unlock enabled, right?
Consider: There is no MIUI on the phone, its a Android One Phone.

You are right, I forgot about OEM unlock option (I enable it by default for all my devices). In this case, data should be safe.
My phone is unlocked but OEM Unlock was disabled in Developer Options... So I think is not a problem having that option disabled.

Try to erase using 'Google Find My Device' i think you can erase the phone using that, also you can know locations where the Device right now.
Just try, Good Luck :good:
Hit 'Thanks' if helped. ASAP
I am fairly certain there would be ways to circumvent the google account verification using fastboot commands and MiFlash. It takes some work and patience, but it should work.
However, as far as I know there are ways to get the IMEIs of the device blocked by carriers when reporting the device stolen. Not entirley sure what needs to be done to do this, but this would render the device useless for the thief.

Imei blocking is not really gonna help. It's too easy to change.
Yes there are ways around everything in this thread and tuts to do it are only a search away. Heck we host most of the tutorials right here.

Device locked by forgotten pattern

Hi,
I tried to change the pattern of my device, it seems that I didn't set what I thought and now that I restarted my system, the device (Android 7) is asking my for a pattern to let me turn it on, that I don't know.
Of course I'm the owner from this device, with my Google account and everything but I made a misstake and I don't know how to fix it.
What are my options now?, Should I restart the device with recovery options, wiping data user and that or what do I need to do?
Regards in advance.
Do you by any chance have TWRP installed? If so, there are certain files you can delete to remove the pattern.
Try it enough times and it should offer to unlock another way, then use your Google account.
And don't use pattern unlock... PIN an fingerprint are fine.

What are the pros and cons of decrypting Oreo?

Trying to determine whether I should decrypt. Encrypted phone requires re-entering the password twice.
Encryption has nothing to do with requiring pin at start up. You can turn it off. And turning off encryption is not something you should do. Anyways to turn start up pin just remove the pin pass or pattern you have currently and then when you add again the first screen that pops up is the confirmation screen asking whether you want startup pin enabled. Select no and you are done..
The only real benefit to decrypting your device is if you use a custom recovery like TWRP--especially if it's not an official build of TWRP.
On some devices (especially those from One Plus) there are issues where TWRP either can't decrypt the data partition or stops being able to decrypt the data partition after an OTA.
On some phones you can just boot back up if that happens but on others you are locked out and need to reformat and reflash just so you can use the device again and if that can't be done which has been the case on some treble phones like the MI-A1 and the Essential PH-1 then your device is permanently bricked and is pretty much just an expensive paperweight.
