Getting checksum error at updateFirmwareFromFile.shj.
I upgraded mdadm accidentally whilst trying to install xfce desktop, managed to stop it before udev was replaced.
The fix is to add metadata 0,90 to /etc/mdadm/mdadm.conf but that configuration file was deleted.
Does anyone have a fix for this so that i can restore the firmware, i guess the contents of mdadm.conf file would do the trick.
