Flint 3: Error Updating Firmware 4.8.5 2026-04-02

Hi,

It looks like you're using a Snapshot build. We recommend reverting to a stable release version.

Here are the suggested steps to try:

  1. Create a backup file through Luci:


  2. Upload the stable firmware version for the BE9300 to the router:
    Firmware download link: GL.iNet download center
    Upload tutorial: Use WinSCP to modify files - GL.iNet Router Docs 4

  3. Run the following command:

sysupgrade /pathto/be9300-4.8.4_release2-965-0131-1769860249.bin
  1. If the downgrade still doesn't work, follow the Uboot tutorial to reflash the firmware:

  2. Afterward, you can restore the configuration by importing the backup file created in Luci. Note that this may fail or only restore part of the configuration.
