How to factory reset Galaxy S7 without password?

You can get into the Recovery Mode on your Galaxy S7 Edge to perform a factory reset. Here’s how:

*Before you perform a hard reset, make sure your phone has enough battery power (at least 50%)

1. Power off your phone.
2. Press and hold the Volume Up + Home + Power buttons at the same time, and then release them as soon as you see “Samsung Galaxy S7 Edge” on your screen.
3. In the Android system recovery mode, use the Volume Up & Down buttons to move the highlight to Wipe data/factory reset, and then press the Power button to select.
4. Select Yes, and your phone will start deleting your data and settings.
5. When it finishes, select Reboot system now.

This is all very good when I power off my Samsung it wants the passcode??

You meant the screen lock passcode is needed when you tried to power off from the lock screen? In that case, you can choose Restart instead of Power off.

After seeing the Samsung logo when powering off(before restarting), you can Press and hold the Volume Up + Home + Power buttons at the same time, and then release them as soon as you see “Samsung Galaxy S7 Edge” on your screen. This will still bring you to the Recovery mode.

I was able to do your instructions but my phone is still asking me to sign in with a google account that has previously been synced on this device after the factory reset. I bought the phone second hand on ebay and hope to get the info from the seller. Any faster way to fix this problem?
Thanks.

Im having the same problem…difference is the person i bought the phone from gave me all the email and pass word info n it still isnt working…need help please

worked straight away thanks i had to use the restart button instead of power off

After doing all things to re start then hard reset is successful but still asking the google account what was previously been sync,,how to solve ? Pls help.

There’s no straight forward way. I’ve seen many videos showing you how to by the google account verification on youtube. The methods shown might not work for all variants but you got to try them. You can start with this one: https://www.youtube.com/watch?v=5NdAqJaoGjk
