I downloaded the "NFE-Tools-v7.1.1" file and was able to update the firmware on my Eleaf with no issues at all using "NToolbox." I also messed with some of the settings and set up different profiles for my device - impressive! Then I went to select a logo within NToolbox, but nothing showed up. I tried to upload the different resource packs located within the "ResourcePacks" file of the NFE-Tools-v7.1.1 download (as I assumed each one of the files within the ResourcePacks folder contained logos, but was not able to do so. I am unable to find any guides on how the whole logo feature/process works, so I was wondering if someone here could explain it to me. I also tried to open these resource packs using 'NFirmwareEditor', by opening the app and then clicking "open," but when I select one of the resource packs such as ArcticFox, or iStick, nothing is available for me to select. I'm just really confused at this point and wish I could find a full tutorial/manual on how to fully utilize the capabilities of this software.
