Abnormal factory reset cant login

My phone says abnormal factory reset and asks me to login to my Samsung acct. This is my old phone and u currently have an edge on the same acct but it wont let me login. Says the user id or password is wrong. Ive changed the password per samsungs advice and it still wont login. I sent it to Samsung since it's under a yr old but they said ut was not repairable. When i called and asked why they said it had an after market screen which it doesnt!!! I argued this point but got nowhere. Thinking maybe i could hire someone to fix it but having no luck. The repair guy told me to look for online advice
