Huawei M3 BTV-W09: Forgitten PIN, how to unlock? - Android Q&A, Help & Troubleshooting

Dear fellows,
I used fingerprint for months. Now my tablet rebooted and it requires PIN, which I already forgot.
I tried Google find my device service. There when I press the Lock button, I get the message "Couldn't lock device".
But if I input any message and then press Lock, my tablet is locked (but Google still says "Couldn't lock device") and the message is displayed on the screen.
Google does not provide unlock service for Huawei M3, I do not know why...
I read everywhere that you should be able to input your Google credentials after you input wrong PIN N times,
but this is not the case for this tablet.
Do you know how can I unlock it? Or at least how can I access and backup all the data? If I do that then factory reset will be fine for me.
Thanks in advance!

[Q] Lost lock pin

Hey!
Changed my lock screen pin today, but apparently entered it wrong (twice?) so it wasn't what I thought it would be...
How do I go about unlocking it? I really don't wanna reset the device or install a new rom!
My Galaxy Nexus is rooted, I have gmail pw, ADB access and pin code...
Please help fast!
Thank you
if the phone still has access to the internet (wifi or data) then once you try to enter the lock pin incorrectly a few times it should ask you to login with your gmail password, which should then unlock the device allowing you to change the lock pin.
Failing that there are methods involving adb, do a search on google as I think some people have unlocked it using adb.

Forgot pattern - never prompts for login credentials

I have a Nexus 7 tablet that I haven't used in a while and I don't remember the pattern lock.
The problem is there's no backup password prompt, and it never asks for my google login no matter how many attempts I make. The device is online. It just says You entered the incorrect pattern 40 times. Try again in 30 seconds.
I tried the android device manager and locked the device with an alternate password but tells me that since there is a screen password set they won't use the password I just entered... which is unhelpful. Any other ideas short of a factory reset?

unlocking Oppo R7 Plus

Hi sir,
Someone had added a new google account & changed the screen lock pattern on my phone (OPPS R7 plus). After I got back the phone, the pattern lock is on. My own google account is still connected to this phone.
But when I click forgot Pattern & keyed in my Google Username and password, it showed "invalid username or password"
Can you advise how I should proceed?
By the way I have also locked the phone from the "Find Your Phone" feature. But it doesn't allow me to replace a new passcode, due to the phone is already locked.

Question FRP Lock after Factory Reset: Confirming Account jst "fails"

Hey folks,
my girlfriend just sold her P6 to a work friend and I wiped the device and thought "thats it". (I even removed the device from the Google Account!)
Sadly thats not it
The phone wants to have a/the? PIN of the device. We never set any PIN (which the google account confirms). What PIN is the device referring to?! Its not the lock-pin she normally used.
Nevertheless the device allows for a recovery via phone number and/or the old google account. We tried that and the P6 even lists the Name of my girlfriend and she gets a login notificiation on her new Pixel 7. But after entering the Password the P6 just say "an error occured, try again." (Ein Fehler ist aufgetreten)
But it doenst matter what we try or how often. We get always back to that screen and into the "an error occured".
So basically we/she are stuck. Any chance I can fix it with some ADB command or anything (dunno if the developer options are even switched on).
Thanks
Bastian
did you try reinstall the stock firmware?
there could be a few different pins
P.U.K is an acronym for Pin Unlock Key
Some carriers also put a SIM PUK on your SIM card when they sell you the SIM card
SIM Network Unlock Pin (NUP) is a code used to unlock an Android phone or iPhone from its original carrier so that it may be used on other carriers
picture of the error might help

I only did a factory reset via bootloader thingy on the phone.

During setup, the unit asking for the pin refers to the screen lock pin or password that was used, and no other. You can try 0000 and see if that works, but it likely won't. If the error persists, contact Google and explain it to them. Only don't be surprised if they can't help you.
The only ways to fix this are as follows: 1) contact Google as mentioned, since there is an error in the process, or 2) attempt to unlock the bootloader. If you can successfully unlock the bootloader, then FRP should not kick in the next time the unit is started. If neither option is available, then ADB will not help you here, as by design Google makes it so FRP cannot be bypassed in so simple a manner.

Ok thanks, I'll contact Google.
There has been one PIN and never any else and this doesn't work.
