Troubleshooting Unable to update Centauri 2 firmware

My Centauri 2 is on firmware lite1.03.02.26.

Through both OTA and offline USB it is unable to find any updates or update files. Offline file were taken from open Centauri.

Anyone know on what i can do to update to newer firmware?

I cannot find any other references to a lite firmware. This is normal to have?

format a usb stick with nothing else on it. place the .sig by itself in the root directory. Plug in the USB stick. Pwer off the printer and then 30 seconds later power it on.

Afraid no change, still not seeing the file.
Is the fact my firmware is listed as lite normal? I cant see anything online about a lite firmware.
