That is awesome information and very helpful. I was successful. I have no idea what happened. I am very confused, but happy that it worked. Thanks for the info though

I am having the same problem, did you ever find a solution?

Same result, downloaded with chrome. EDIT: Reformatted again and used the files downloaded with chrome, it saw them. both updated all the way to 5.4.27 successfully.

I will give that a shot. I don't have any other ideas at this point.

alright, loaded a new .ufp onto the USB root directory, those 2 printers saw it fine. Additionally, I have used this same USB to update 6 other S5s to 5.4.27 that were purchased later and had firmware later than 5.1.94 from the factory, so I suspect that the usb works.

yup, that's the plan if I can get it to that point.

I am trying to update 2 S5s at my work. They are not connected to the internet, cannot be, and They have 5.1.8.20181207 and 5.1.7.20181023. Following the instructions on the Firmware Update page, I downloaded rootfs-5.1.94.20190425.tar.xz rootfs-5.1.94.20190425.tar.xz.sig and placed them on a FAT32 USB. when plugged into either S5, I went to >Update Firmware and nothing appeared. I attempted power cycling, factory resetting, reformatting to FAT32, zero pass reformatting to NTFS, CuraConnect resetting, and removing 'root' fr
