Spirit System

I was setting up a new Spirit GTR unit on a heli and i had just completed setting up all the parameters, level swash, limits etc. I then set the fail safe condition by pressing set fail safe. The unit rebooted and since then has failed to connect to the software and also the radio even though the receiver is bound and i can even see the EX telemetry sensor that is connected. Power cycling the unit, the status light keeps on flashing and it never initializes.

Would appreciate any help.

Thanks
