I have a profiler that has OS 3.3x and I am trying to update to the latest from the website, 5.1x. It appears that I can't use a new enough PC software to the the update via PC, I must use a USB stick. I have tried two different sticks, my unit recognizes them, formats them correctly, and I can back up rigs to the USB stick. However, copying over the KAOS.BIN file to either the Operating System folder or root folder and re-inserting into kemper and I never get a notification to update the OS -- I have tried booting with it in, inserting it when it is in browse mode, etc nothing works. I have tried powering up with EXIT depressed and attempting to run directly from the USB drive with KAOS.BIN in the root directory -- it tells me that the file is invalid. I found one very old forum thread where someone had an identical problem, but there was no resolution posted. Anyone had this come up? Fix?
Thanks!
