So you tried to put your passcode in and it didn't work?
With what you said, not sure what exactly happened, but this might help if you can't get into the device.
Connect your device to the computer you synced with.
Open iTunes. ...
Wait for iTunes to sync your device and make a backup. ...
Once the sync and backup have finished,click Restore [your device].
When you reach the Set Up screen while restoring your iOS device, tap Restore from iTunes backup.
