Without the proper credentials, you may just be locked out

 

unfortunately there is not much you can do unless there is a forget password function on the phone......which in most phones there isn't, especially when it comes to pins as the lockscreen security. the only way to unlock the phone is to do a hard rest. but you will trip frp (factory reset protection). as long as your google acct info is good then you should be fine. unless you used a different google account initially on the phone and never changed it.....then you will most likely need the original google acct info.

regardless your data is gone..........sorry
