GX450 ALEOS 4.9 FW Upgrade


I am getting this error when trying to upgrade from 4.5.1 to 4.9.0.
Extracting tar file failed (Invalid argument)

I use the Verizon network and corresponding upgrade file.
Any help on this issue, much appreciated.


Same, but only on 2 of my modems. A few others worked fine.


I’ve got 8 GX450s that refuse to update…extracting tar file failed. No help from Sierra here, I guess.


Any time I have FW upgrade issues. I do a factory reset on the unit then try the upgrade again.


Tried that multiple times, have tried going from 4.5.1 to 4.8.0, have tried 4.5.1 to 4.9.3 / no success and not a peep from SW


if you have a service contract, send the unit back and tell them it is defective. Make them fix it, dunno what else you could do. Good luck.


can anybody help me to find a firmware for gx450 4.9.0?
I will be very grateful if you send me it to the danny.longhow@gmail.com, for example
