I've got the following logfile.txt:
Flash kernel:
Integrity check on kernel

k.
Flash the kernel:
-- Kernel flashed OK --
Flash initrd:
Integrity check on initrd

k.
Flash the initrd:
-- Initrd flashed OK --
Flash application filesystem:
Integrity check on app.image.gz:
ok.
Flash the filesystem:
-- Filesystem flashed OK --
This was usual reflash. And after the change :
Unknown action, do nothing
and again
Unknown action, do nothing
