System Image Filename Explanation​

  • System file naming rule: FlyOS-Fast-[chip series]-[version number].img, for example: FlyOS-Fast-H5-v1.0.0.img.
  • The source file is in .img format. Only .exe and .7z compressed files are provided in the download link for convenience.
  • Windows users should download the .exe file, which is a self-extracting 7z archive. After downloading, double-click it to extract and get the .img file (this can only be done on Windows).
  • Users of other systems like MacOS or Linux should download the .7z file, which is a 7z archive. After downloading, use a tool that supports 7z format to extract and get the .img file.
  • Due to the large size of the system files, other compression formats and source images are temporarily not available for download.
