Spirit RS, after upgrade to 3.2.2 unit is only flashing blue

Hi,
i just upgraded my Spirit RS to Heli Version 3.2.2. After successful update (!) I wanted to restart the unit (disconnected battery) but after reconnect the unit is only flashing blue (like pulsing)
I have already tried the recovery mode to Version 3.2.1, which was successfully finished, the unit initialized and when i restarted the Windows Software the unit seems ok with all previous settings.
BUT when I disconnect and reconnect battery the unit is flashing constantly blue again and no connection from Windows Software is possible. So it seems that it looses the firmware after disconnecting battery. I have also tried recovery to 3.2.2 and older versions with the same result.

Thanks,
Tino

I'm assuming something went wrong your end rather than a problem with the software??

You are welcome. It was not possible to determine reason for the issue exactly, but it was fixed with special firmware which returned unit to previous condition. Then firmware 3.2.2 was flashed normally.
The issue could happen when unit is powered off before unit is initialized right after flashing new firmware. But solution is easy.
