Hello,
Anyone who has the same problem? I can't mass-upgrade RoS from dude...

You have to upload the upgrade file to the Dude's file structure, into the Dude Data Files. Then you can click on one device or several and select upgrade and then the package you want to upgrade to. My problem is the upgrade of several of my devices do not work. It reboots but does not install.

am having similar problem with SWOS on a RB260gps upgrading from 2.4 to 2.8 firmware. Tried to upgrade half a dozen times to no avail. Had to climb down the tower and give up. Would like to know what the problem was before the unit gets scrapped.
