Hello,
It is possible to do it locally. Be aware, that the following instructions apply to the devices with USB ports and RUTX series, which have sufficient memory to store the required files.
In order to update, you will need to:
Download the firmware zip from this link.
Extract the contents of the zip to a separate folder, for example Update. Delete PDF with Chinese symbols as it might cause issues.
Copy the Update folder to a USB drive or, if you have available space, using WinSCP, copy it to the router's /tmp directory.
As instructed previously, download modem_updater and sshfs.
If the folder is stored in USB, attach the USB drive to the router, and execute the following command:
- modem_updater -i 3-1 -p /mnt/sda1/Update/
If the folder is placed in /tmp directory, the command should look like this:
- modem_updater -i 3-1 -p /tmp/Update/
The rest of the update should happen automatically.
Best regards,
