Not allowed to set the device owner

问题

I know question has been asked but i can't get device ownership.

I'm with a samsung xcover 4 with android 7.0.

I launch this command :

C:\Users\xxx\AppData\Local\Android\Sdk\platform-tools>adb shell dpm set-device-owner org.wso2.iot.system.service/.ServiceDeviceAdminReceiver

I get this error :

java.lang.IllegalStateException: Not allowed to set the device owner because the

factory reset done. I also disable and uninstall all applications but still no luck. Any solution? Thanks.

As the error states

because there are already some accounts on the device

Go to Settings -> Accounts and remove all accounts (like Gmail, Facebook, ...). When there are no more accounts, try again.
