My dears my sister has given our little sister her cell phone we just set it back well and now we're completely out of the phone.
It stands this device has been reset. To continue log in with a googel account that was previously synced on this phone.
Unfortunately we do not know any further you can help.lg
Actually that's the answer.
When you first set up the phone, you probably created an account on Google, or used one existing account.
You need this data now.
Question: Did you reset the phone to factory settings? Then it should actually be possible to create a new Google account.
That's the problem, we have entered the data of my sister who has used the cell phone before, but he does not accept it has reset the phone only to factory settings but it is always the same text, please enter the username of the owner, the phone is pure theoretically completely locked
Did you try logging in with your google account?
Maybe this will help you:

Visit this page with the sister's Google Account. Find and remove the "old" phone. Restart the device of the mobile phone. If that does not help, unfortunately, I can't help you.
You have to sign up with the Google account that has logged on as the first thing on this phone. So the account that was logged in the first time the phone is started is set as the owner. If you no longer have the data you need to flash the phone and install a custom firmware. If the technical know-how is lacking go to a specialist. But then you need the bill or other evidence that your cell phone is because it could theoretically be stolen and you want to use the phone.
