Samsung Phone Locked Due to Wrong Pattern

Remembering the incident this morning when my friend and I idly fiddled with the pattern of the Samsung cellphone to unlock it, after several failed times finally the Samsung cellphone was locked and had to enter the email and password.
Waduuuhh.....!! I panicked as well as my friend, the only way I asked for email and password was on the one who had a cellphone. Unfortunately, those who have Samsung phones forget passwords and usernames when creating an account for the cellphone, as a result I have to be responsible and have to be able to reopen it as before.

After trying to log in to google using a computer, I tried some emails and passwords that he remembered, finally found it too but,,, cellphone could not be opened the problem was that the locked cellphone was in an Offline state so it could not send data to the google account. There is no other way I have to reset to factory settings at the risk of losing some previously installed data, but nothing important Samsung phones can open.

Here's how to reset or reset a locked cellphone back to factory settings.
This method applies to all types of Samsung Young phones.

1. Make sure your Samsung phone is off
2. Press volume up + Home + Power buttons at the same time
3. Wait until the Android system recovery display appears
4. Select option 3 (wipe data/factory reset) using volume down
5. After that select yes delete all user. Use volume down
6. Finally, select reboot now
7. Wait until your phone finishes rebooting and your phone is back again with a new look.
   
   Hope these simple tips are useful.
