My MX-980 will not go past the splash screen. It says "Loading System Files" and just hangs there.

I have searched all the threads and tried

pushing all the buttons once with battery out
hitting the silver reset button (with no other keys)
hitting watch and enter together.


I can connect it via USB and downloaded a basic file and it still did not work. I reloaded my orginal file and it is still hanging.

Can someone please help with some suggestions?

Thanks in advance
