Cube Orange APM Initialising

This Cube Orange has been used many times in a multi-rotor over the past few months.
Today it failed with this message (“APM Initialising”) being generated constantly.
Can connect via USB and attempt Firmware Update. It currently has 4.07 on board and this is detected.
The Parameter Set can be downloaded on connection via a RFD 900 link.
It emits the correct tones during boot up.
The orange LED underneath the Cube stays on.
No AHRS movement on MP.
Any advice would be appreciated please.

Same here i was flash inav to arducopter 4.0.7 and it’s keep showing apm still initializing and some time altitude gone crazy :joy:

I guess fw problem ?
