So I installed mib2-toolbox this afternoon. While checking out the settings it has available I must have done something wrong as my Discover Pro (MIB2.5) is now stuck on the boot splash screen.

The big problem is because I can't access any of the device menus I can't get back into the green developer menu to undo what I've done, nor can I enter the service menu to reflash firmware and overwrite back to factory default.

Any suggestions on what I can do here please?
