Hold down the touch button until you're prompted to reset. It may take up to 20 seconds.
If that doesn't help, or it won't reset, try calling the 800-SAMSUNG customer service center for troubleshooting or repair service.
I am trying to factory reset my blu ready player due to it not paying DVDs anymore. I'm piety sure it posted them before the latest firmware update a few Weeks ago. Samsung keeps sending info about holding down the stop button on the front panel to reset but they should know that this has a touch panel and the stop button is not active until a disc is in the player. Can anyone help?
