Is there a way to know with certainty that it has pulled all the chunks? I've been watching mine pretty closely the last couple of days. I've seen 5 files 4U5T-14G421-CDD_1615428361000.TAR.GZ, ....-CED_, ...-.CFD_, ....-CGD_, and ....-CHD_ download. CHD was the last file that downloaded today. This evening, when I checked for updates, it tells me my system is up to date. Seems like ....-CJD_ should have shown up after CHD downloaded. Is it safe to assume the other files download before I was aware of the TravelLink problem and paying close attention to updates? When updates are done via a thumb drive, the system automatically reboots itself during the installation process. When does the rebooting occur (if at all) during an OTA update? I guess like others have done, once I'm certain the NA 220 update is complete, I should do a master reset. Any thoughts will be appreciated.
