RV50 Firmware upgrade failed, device unresponsive

I tried updating the FW to 4.12.0 OTA on two RV50 devices and both failed, and now the devices are unresponsive. The power LED comes on but no other LEDs light up ever. Factory reset doesn’t change this. Cannot connect via ACEmanager OTA, USB, or direct Ethernet, and cannot ping the devices.

Any suggestions? Thanks!

I have the same issue. So far, no answers and no resolution!

Same issue here, tried updating to 4.12 and one RV50 worked, the other never came back? Called sierra for support and was told modem was out of warranty. Got no help at all.

Tried factory reset, but nothing works. Just get a green power light and no other LEDs. Surely there is a way to recover the modem after a failed firmware upgrade? My prior ALEOS was 4.5, so the recovery mode is not available.

Anyone have any suggestions, other than throwing the modem in the trash?

Please note that the firmware update can take up to 30 minutes to complete. The update is completed when “Install application” job on AVMS server is set to finished.

  6. Click Update.
    The screen lets you know that the update was successful and automatically reboots
    the gateway.
    When the reboot is complete, the gateway exits Recovery mode, and the ACEmanager
    Login screen appears.
