I'm sorry to hear that you're having this issue.
The FF>> should be the final step in attempting to reset it. If you haven't already, remove the disc from the player, and then hold down the FF>> until it resets.
If you continue to experience trouble, I would recommend calling 800-SAMSUNG and having the unit sent in for repairs.
As many others have had this issue, it happened to me last night. I have read many of the threads here and tried many of the fixes, no luck. The BD just sticks on showing load as soon as I turn it on. I have the firmware updates ready on a USB drive but not way to access the menus. I have tried unplugging the machine, I've tried holding the FF button to reset it, I've turned off anynet+ on my TV but obviously can't access the BD's menu to turn it off. Please help me out here, what am I missing? It seems like most other people can get into the menus without having to ship it out so I'm hoping that I am just missing something. Thanks for any and all help.
