I recently upgraded all of our wireless units from 8.4.2 to 13.2. I'm not sure whether these are PMP 400 or 430 units, but I'm not able to upgrade past 13.2 using the OFDM (DES) 13.4 package available for PMP 430s, but I was able to use the PMP 430 13.2 (DES) package to get them to that version.
This is unfortunate, as some of them are giving us false radar detections and then not properly switching over to a different frequency resulting in a need to reboot. I have downgraded some back to 12.2 for the time being.
Any ideas here? Attempting to upgrade to 13.4 simply produces a "Update file not found" message within CNUT. I am running the very latest version of CNUT too (as of a few days ago).
