Looking in service manual I see 99.09.67 code is "Disk is not bootable please download firmware". Problem is when I try and download F/W with a thumb drive it looks like it is going to load then it stops and "unknown error" comes up.
This machine was working fine until I turned it off to install a maintenance kit, when I turned it back on the 99.09.67 came up.
Thanks for any help
