f5434964: ...after a last soft-reset the system came up with the Windows Backupscreen where one could choose between "Beomaster5" and "Beomaster5Recovery"
DISCONNECT the BM 5 for SEVERAL (10-15) MINUTES FROM POWER - reconnect the mains and
when the black boot-screen lets you choose between "Beomaster 5" and "Beomaster 5 Recovery"
select "Recovery".
Be patient, don't disturb this process - it may take a while.
During this process the unit may boot - be patient till the unit (hopefully)
comes "back to live" again.
After this you should trigger a "manual software update" to install the recent SW version again, and,
as before, don't disturb ...
