Password after hard reset - Samsung Galaxy A51 Questions & Answers

Hi guys, i have a samsung a51 and i had to hard reset because i forgot the pin to unlock the phone. Now after restarting, it needs old pin or google account. I don't remember the old pin and the google account. I tried to install TWRP and then install a custom rom, but the phone needs to unlock the bootloader from developer settings that i can't activate because i can't start the phone.
Thank you all.

Please Help!!! Samsung J700P keeps re-locking google account

Hi I need some help with a customer J7 boost mobile, She purchased a Galaxy J7 and the phone was defective and she has to send it to Samsung for repair, the phone was fixed and send it back to her. the problem was that they reset her phone and now is asking for the google account password. ( she doesn't remember her login and password)
so the only solution was to bypass the security lock, I tried OTG cable and didn't work, I tried side sync and didn't work, the only working method was to call 611 and from there going to the internet, download shortcut maker and from there to settings and reset and voila! Right? BUT NO!!!
The first think I noticed is that doesn't let me go into developer mode by typing the build number, kernel,baseband, nothing :crying: developer was lock. the second is that when I reset the phone from the actual phone (with short cut maker) the phone will reset and then reinstall everything back again, I know because the customer had Spanish language by default, I tried again call 611 and go to the internet, download shortcut maker go settings check is any account on google (none) try to open developer mode (none) reset the phone and AGAIN the phone reset and and reinstall and lock again, I tried odin and root but google account block any try to root the phone, try odin with stock image and the same install and after reinstall and lock again. Could Samsung did something to the phone ? I seen videos unloking the J700H but nothing on boost mobile J700P? anyone knows hot to fix this ... thanks in advance
see this guy

If you can access your Google account, you should be able to reset your password.

Unable to reset S6 - Says abnormal factory reset

Hi all
I've recently reset my wife's phone so my son can use it.
However, after factory reset (using the buttons) when it reboots I cannot set it up.
It says that an "Abnormal factory reset" has been performed and asks for my wife's Samsung email/password.
When we put this in - it's rejected (actually, it says signing in but nothing happens).
We've reset the password but it still won't work.
I'd be happy to just format it an put a clean custom ROM on it but I don't know how.
All guides I find say it needs to be rooted first and to enable USB developer options - but I cannot unlock the phone to get to this stage.
Could someone please help me figure it out? Samsung can't (they want us to send it to them for a chargeable repair!)
Thanks
Matt

Hi, you don't need to root before flashing.
Samsung is AWESOME FOR THIS.
You can flash at any desperate moment.
It is time to install Android 10 for the dummies : https://forum.xda-developers.com/galaxy-s6/general/guide-tutorial-howto-samsung-galaxy-s6-t4108425
Thanks. I managed to fix it though.
I had to get the L2 Samsung account support to disable two-factor authentication.
Then the password worked and the phone unlocked.
The "this phone is blocked" screen requires your Samsung password but isn't smart enough to work with two factor auth (which is default turned on for all Samsung accounts). #facepalm

Nope the twofacauth is not turned on by default for Sam acc or any other acc on this Planet...that must be activate and config by user.
But if you have the right knowledge you could flash other Rom even if the Phone is lock by google. You just need to know how to.

[Need Help] Is there any way to unlock my phone without losing any data?

I'm using samsung galaxy A51 global version.
Recently, I changed my lock screen pin code at night and never tried to unlock with the pin until the pin code is required instead fingerprint.
So, when I tried to unlock with the pin code , it says the pin is incorrect. I tried pin several times but failed and it's time blocked and there is no option to reset password like older versions of samsung phones.
I have so many personal data in my phone, so I need to unlock my phone somehow. Please, help me if there is any way to unlock the phone without losing the internal memory data.
hello good, enter your Gmail account, from there you can change the password.

Hi, Its only possible if u already had twrp installed, in that case enter the twrp file manager and delete the following:
/data/system/locksettings.db
/data/system/locksettings.db-shm
/data/system/locksettings.db-wal
you can enter google from a computer, enter search and change password
