Password request suddenly - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hi,
I need help, my father has a samsung A3 with ROM stock, he knowns 0 about android but he needs phone to work.
He doesn´t have a password code to unlock the phone, but this afternoon, he calls me (with another phone) telling me that suddenly the phone was blocked and he doesn´t knowns the password, he doesn´t put any security code, is like that it appears for "magic". We tried all, i have tried 70 passwords without resoults. I can see the device in android device manager, but i can´t restore the password there. I unlock the SIM but not the phone code.
How can i resolve this?
Any help would be appreciated

Factory reset is probably the only way. This will wipe ALL user data.
Also be aware this may activate Google FRP Lock.
If it does you will need to input the Google sign in details.

I dont think there is any way to bypass an unlock code, however it was set. It is after all there to protect your phone from unwanted use. The only course of action I can sugest is to Hard Reset it back to factory settings which would erase the unlock code but would also erase all msgs, contacts, settings and installed appications on your phone. At least you would be able to get back into it though.

[Q] Recover Pictures - PIN locked - Please Help

Hello,
I have an i337 that is PIN locked and unfortunately the owner has passed away. The family of the owner has asked me if I am able to retrieve the pictures off of the device for them, but they do not know the PIN. Sadly, there is not an SD card, nor a Google account (I can enter the password incorrectly indefinitely without being prompted), and I am unable to get any information by attaching it to my PC. As far as I am able to tell the phone is stock and not rooted. Booting into recovery shows me KOT49H.I337UCUFNC1. If there is any more information I can provide, I am unsure where to find it. I've done a few searches but haven't found anything that works for me. One of my thoughts was trying to find a rom to flash with Odin that doesn't wipe the internal SD card, but I can't seem to find one for this device, if such a thing even exists. If anyone has any experience bypassing a PIN without losing data or has any suggestions that would be of help in this particular situation I would be greatly appreciative.
Thanks,
Kylor R

Is it possible to reinstall android without unlocked bootloader?

Hello! From time to time I keep myself busy with smartphones. Now i've got P9 Lite with an issue that is difficult for me to fix. The first problem was about SIM lock i guess. The phone couldn't read new SIM card. My dad did a factory reset through recovery mode and here starts the real problem. I CAN'T LOG TO ANOTHER GOOGLE ACCOUNT THAN ONE BEFORE FACTORY RESET. To remove SIM lock I have to reinstall the whole system but i can't do that because bootloader is locked. I can't unlock it because i can't get into the phone and I don't own it so I have no box with IMEI numbers and so on. I'll try to contact the person who owns the phone about the google account before but I wonder maybe there's another solution? Thanks in advance.

Samsung galaxy J5 found

Hello guys!
Today i found Samsung J5 at the pavement, closed but when i tried to open it it opens just fine, has a sim card inside and even a home lock screen photo with a girl and a boy that i see at the background. So someone has lost it.
I'm trying to open it to send a message to any contact of the owner, that i have found it and to come get it back.
I tried to get into recovery to mount and get the passwords erased (according to a video i found at youtube -link at the bottom)
but the recovery it has now doesn't work and when i try to install the twrp through Odin it says "custom binary blocked by frp".
How can i get it to work?
Or any other ideas?
Thank you!

I see you have honest opinion, but sorry, since the owner didn't enable oem unlock, there is pretty much nothing you can do but flash stock rom using odin and use it yourself...
Just insert that sim card in another phone and wait for calls, or try importing contacts from the sim card onto your phone, if you really want to find its actual owner...
Edit: It might require a password for the sim card.
Ragazzza, i can not use it for myself, even if i wanted to, cause it is locked through and through. It has FRP enabled and it is unusable. I went to the company of the sim card and they told me they can't do anything, i just have to go to the police and they find the owner. I wento the police and they told me to take it to them. The only thing if that i'm afraid they maybe will take it for themselves. That's why i do not want to take it to them. Of course, if i can't find a solution i will do it.
Gent, well i haven't thought of that! But i do not think that it'll work because what we do in Greece is we tell the company we have the number to deactivate the lost sim, and give us a new sim with the same number. Also, the sim card has a pin, so... :/
So the sim i have now in my hands is useless, propably. I'll give it a try though, thanks for the idea!
Don't wipe the device in stock recovery. You will end up locked out by FRP.
Is there an sdcard in the device that could give clues to the owner?
Also I find it hard to believe that the network company of the sim card cannot help. If it's contract they should have no problem tracing the owner via the sim card number or even IMEI of the device.
Is the SIM card actually locked?
ashyx, i do not know where you are from but in Greece, unfortunately, things do not work like in other countries. I have gone to 2 stores, in both stores told me the same thing. "we can't do anything sorry. Go to the police to declare it lost". I do not trust the police will do it's job rightfully so i prefer to search for a solution, even if it takes time.
I got FRP lock, indeed. No sdcard :\ I actually found a program called Wondershare Dr.Fone but neither of my phones are supported....

So at the moment you are FRP locked because you attempted to install TWRP or can it still boot to the lock screen?

I attempted to instal TWRP and it gave me this message "custom binary blocked by frp". But i can boot to the lock screen if i take out the sim card.

I'm surprised the owner hasn't attempted to call the phone.
The first thing I do is call the phone if I lose it and hope someone answers.
It should still be possible for you to pick up the call even if it's locked.
ashyx, not if the sim card is locked. If it was only the phone i wouldn't have a problem answering any calls to give the phone back. But it's both sim and phone locked. Or else i wouldn't have a any problems solving this

Unlock code not working. Help please!

Hi.
I have purchased an unlock code from samsungsimunlock but my phone is still SIM locked. They sent me code along with a link to an app to download called Network Unlock app. I ran the app, entered the code, get a message saying phone is perma unlocked but when I insert a non Vodafone SIM, the phone, not the app, asks me for the SIM unlock code.
EDIT: Phone details:
Locked to Vodafone UK
Galaxy S8 SM-G950F
Android 7.0
Baseband version: G950FXXU1AQH3
Knox 2.8
I had rooted my phone and as the instructions from SSU said to, I removed the root and returned the phone back to stock (as far as I know)
Can any one help with this please? Is the unlock possible after knox has been tripped?
I would really appreciate any help,
Thank you
Try log in to your Samsung Account on a Desktop then, reboot your phone. - Helped me out a few times when I've not been able to log in.

I can't see how this would help...
Put this in your dialer #7465625*638*# then try your code on the network unlock screen. See if that makes a difference
