I have two WorkCentre 5150s, both initially running firmware v021.120.052.000.
I am trying to update to the latest SPAR release I could find, v021.120.065.270, to address issues scanning via SMB (w/out NetBIOS) to a new Server 2012 box.
The first device updated via CWIS without a problem. The second device begins the software upgrade, displays the various progress bars on the device control panel, but restarts after 3-5 minutes and boots normally to the old firmware without continuing the update. I have tried initiating the update via CWIS multiple times now with the same result.
This is not a single-board controller 5150, so as far as I know CWIS is the only option I have to update (no USB Flash Drive update).
