Hi All
I have been trying to upgrade the firmware for the 5 x M200 plus machines that we have in our STEM centre as the firmware updates have got a little far behind. In know previously I had to install rolling upgrades e.g from 1.0.6 to 1.1.0 then to 1.1.1. However, I cannot go any further as 1.2.0 does not seem to update. I am using a USB installation and it recognises the update file and goes through the process, but when the printer restarts the firmware version still says 1.1.1. I have tried this process on each of our 5 printers with the same result
