I have a Rich Auto A11E that drives my Laguna woodworking CNC. Haven't had any issues with it until now.

I disconnected the handheld controller to install a longer cable.

When I start the controller normally, it starts its load cycle but freezes at 93%.

When I start the controller while holding the Origin/OK button, it starts a seemingly different load cycle but freezes at 40%.

When I start the controller while holding BOTH the Origin/OK button and the Stop/Cancel button the screen just says "Flash Disk Mode".

I tried reverting to the old cable, as well as tried starting the controller with and without a USB drive inserted.

I saw videos online about updating the software, so I downloaded the latest from Download Beijing RichAuto S&T Co. Ltd, but I can't go to the Emergency State menu that would allow me to install the new software.

Is it bricked? Thanks!
