System Image File Name Explanation

• The naming rule for system files is: FlyOS-Fast-[chip series]-[version number].img, e.g., 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 can download the .exe file, which is a 7z self-extracting archive. After downloading, double-click to open and extract to get the .img file (this can only be extracted using Windows).
• Users of other systems such as MacOS or Linux can download the .7z file, which is a 7z compressed package. After downloading, use a tool that supports the 7z format to extract and obtain the .img file.
• Due to the large size of the system files, other compression formats and the original image files are temporarily unavailable for download.
