Modem firmware update fails (rutx09)


A modem firmware is available but updating fails. Is it possible to do the modem update over 4G? I accidently pressed update assuming it was the router firmware. Luckily the router came back online…

I have the same problem on a RUTX12. Primary modem has updated, but update of the Secondary modem keeps failing. No further explanation or error code.


We have removed some of the comments in this comment section that discussed a procedure for updating the modem. This procedure is meant for internal use or special cases where the standard method is not available. However, this procedure is quite complex and risky, as any interruption in power or connection could cause irreversible damage to the modem. Therefore, we have decided to delete the information related to this procedure.

The recommended way to update the modem is to use the DFOTA service by navigating to System → Firmware. This is much safer and simpler than the alternative procedure.
