Yes those are what I have been using use but they just say Armbian not ArmbianTV on the filenames. Maybe you use the term interchangeably?
Are you sure you have a Quartz64 model ? Which eMMC module do you use ? Run Armbian and show the output of the "fdisk -l" command. Try to completely erase eMMC from Armbian (with the dd command) and perform the entire installation procedure from the beginning (installing Armbian, and then installing LE).
