Hi milhouse

I've just updated this via devupdater but on reboot nothing happened system looks dead.

I was going to try and manually add the kernal/system file before posting this message but just needed to ask would it make any difference before I remove the drive.

Hard to say without knowing why the system is "dead". But so long as you don't have catastrophic file system corruption of /storage you should be able to resurrect the system by manually copying the boot files into the FAT partition.
