This has been an issue for years... trying to update the firmware on my HP Latex 360.
I have tried to update the firmware a few different ways... from the printer panel, from the web browser, as well as manually downloading and uploading the specific firmware via web browser... all with no success and different errors.
One error I receive is 74:01 "The firmware file could not be uploaded to the printer."
Another is a Connectivity error.. "The firmware update package signature is wrong or missing."
I have googled these errors/this issue and don't see any legitimate solutions. I tried a recommended solution to... "power printer off, unplug power cables, reseat and power back on, try update again..." This did nothing.
Currently installed FW version is NEXUS_01_16_00.8
New FW version is NEXUS_01_18_11.1
Any suggestions/solutions are appreciated.
Thank you for your time

if you haven't tried yet with USB flash drive (FD), it's still the sure way of installing firmware, but some checks must be done before uploading from FD - make sure flash drive is FAT32 formatted, USB 2.0 compatible, 2GB at least and no errors are present. Download firmware file and check integrity - must be downloaded completely not partially or with some errors (if cancelled downloading of broken net connectivity, try not to continue but to download again whole file). Copy firmware file to FD without errors and it must be only this file there. (also may check after copying for no errors the FD) Turn off printer from front panel button, insert FD in USB slot, turn on printer and observe instructions on front panel. If all is OK, new Firmware should be installing and follow procedures. But if some errors are with new version, try to remove some unused substrate profiles, do file integrity check also - go to Front panel - Settings - Preventive maint. tasks - File system check. And try to repeat Firmware update procedure from flash drive...
