I have a RUTX09 which now just has an illuminated power LED and and all 5 signal strength LEDs flash together - I’ve tried factory reseting and also run the power up sequence to put it into boot mode, however while the Ethernet activity ports flash as they are supposed to, the device always reverts back to this state with 5 flashing LEDs.
I can’t find any reference to this LED sequence online - can anyone advise?
Is there anything I can do to ‘unbrick’ the router which up until now has worked flawlessly.
In the first instance, can you advise if you are able to access the device itself via it’s IP address?
You also mentioned that the device used to work. Did you make a configuration change to put the device in this state? Or is it random?
Also to check, have you tried this Sim card in another device or your phone? Or another Sim in this device. Try putting the Sim card in another Sim slot.
In your case I would advise to please also try to perform a bootloader reset on the device. This unique feature allows you to perform firmware update and reflash the device, which can potentially resolve the issue.

In your case, if the device’s led’s are still flashing after trying to put the device in the bootloader state a few times, and you are unable to resolve the issue with this step, I would recommend to contact your distributor for an RMA.
