Reinstall failed: no filesystem found

After not so successful 4.9 kernel tryout on Vero 4K I wanted to reinstall OSMC with the image OSMC_TGT_vero3_20201227.img, downloaded by osmc installer app.
USB stick shows following files on it:
% ls -l /Volumes/NO\ NAME
total 476240
-rwxrwxrwx 1 staff staff 112640 Dec 27 13:50 dtb.img
-rwxrwxrwx 1 staff staff 219197388 Dec 27 05:37 filesystem.tar.xz
-rwxrwxrwx 1 staff staff 24522752 Dec 27 13:50 kernel.img

Booting Vero 4K from USB shows kernel messages, and then blue installation screen, and “Installation failed: no filesystem found” over white bar.

Make sure you don’t have two USB drives attached or a microSD inserted. Only the reinstallation USB should be attached.

Thanks, microSD was indeed inserted. Reinstall in progress.
