This is my first time trying debian but I already tried LMDE 4 and I have no problem in LMDE 4 that's why I thought there will be also no problem using debian live that's why I downloaded debian-live-10.4.0-amd64-lxqt.iso.torrent and not debian-live-10.4.0-amd64-lxqt+nonfree.iso.torrent and now I can't download debian live + non-free firmware because I only have limited data.
When I boot in debian live I saw a non-free firmware error and show me to go in debian wiki about firmware and boot me in full screen command line.
I already downloaded the non-free firmware
firmware.zip but what I can do about it to work debian live? Pls don't provide me a solution to install debian because I want to boot in live usb.
