Herelink Air Unit usb port capabilities

Hello everyone,

I just made a post about this here but I figured this thread was also somewhat relevant.

I know that Herelink root access has been disabled and there is a new way to load custom apps (custom version of QGC) onto the hardware using flashboot. However, I followed all of the instructions for the image creation and flashing, but my machine gets stuck immediately and indefinitely on “sending”. Has anyone been able to successfully load their own custom QGC onto a Herelink remote unit using the image flash method? For reference, I am working in virtual Ubuntu 18.04 on VirtualBox
