There's no problem known with calypso FW update that could result in broken 
So I suggest you double-check your SHR rootfs to be correct, esp wrt scenarii 
files. You might want to call
mickeyterm -c


if that doesn't help

please log in to the flashing-uSD system via ssh (after the initial flashing 
finished. you can boot from this uSD a second time without doing any harm).
In root's home dir you should find to shellscripts, called sth like 
flash-moko11 (iirc) and flash-moko8 or sth. you can easily call these scripts 
to downgrade to a former version of calypso-fw, or even edit to your needs.
