On Christmas, Santa delivered to me a new NPC with a main firmware revision level of 048. I downloaded what appears to be a later version of firmware, 052, from the website, unzipped it and put the 5 files onto a FAT formatted 4GB thumb drive (the smallest that I have).
I powered the system down, installed the thumb drive into the firmware port on back of the unit and turned the power back on. The NPC booted into what is its normal operating screen and, after 24 seconds, the screen went blank. The light on the thumb drive flashed rapidly on and off for at least 10 minutes (the possible wait time suggested in the manual) and nothing happened. No firmware update, no error message, nada… Just the rapid on/off of the activity light on the flash drive.
Any idea what’s going on or what, if there’s an operator problem, what I have done wrong?
Thanks in advance!
