Resetting Nexus 6 requires previous account Same wifi
previous person registered on the phone left
I reset the phone
after language selection (and wifi selection), I get the problem


Device says

This device was reset. To continue, sign in with a Google Account that was previously synced on this device.

Does anyone know how I might fix this problem? It's an important test phone for me.

Again it’s the same wifi as previously.

I looked How to bypass &quot;Verify your account&quot; (Factory Reset Protection) but Nexus 6 does not have such a home button.
This is an anti-theft policy put in place by Google. There is not supposed to be any way to use the phone unless you have access to a prior account used on the device. See the Nexus documentation.

The user with access to a prior account should remove that user to allow future access: 


  To turn off device protection, remove your Google account from your device. If you have Developer options enabled on your device, you can also go to Settings Settings > Developer options and check "OEM Unlocking."
