Luban not communicating with A350/unable to update firmware?

I finally figured out my filament issues, only to hit a hard and sudden brick wall. Days after my latest print, whenever I try to export files to my A350 I get an error saying I need to update my firmware. No problem, right? Well, my A350 doesn’t read any USB drive I have (FAT32, MBR, no folder/directory). And when I go into settings manually, there is no option to update firmware.

Help, please?

Is there an issue with the USB plug in your machine?
Are you able to transfer print files via USB?

I am not able to transfer files by USB, no. I have never been able to. I have always transferred then via wifi as a workaround.

Are you able to add the update file to your luban workspace with manual import it on the top right side and send it to the machines?
Then you shall be able to run the update just from touchscreen.
