RT-AX88U E3372h no longer working

I have an E3372h-608 dongle for Optus using secondary wan as failover. It used to work fine but noticed now its not detecting the dongle properly. 

It keeps telling me network cable is unplugged. It works tine on a windows Laptop to connect. Havent changed any settings but did play around a lot with the connection settings but I feel that is not the issue but the issue is the firmware is not able to set the usb mode for the stick because its being detected as a CD-ROM and when I went it to try and run usbmode -l or usbmode  -s I got this:

json_object_from_file: error opening file /etc/usb-mode.json: No such file or directory
Failed to load config file

 I googled then about the usb-mode.json and found one that supposedly works with the e3372h so added it:

"12d1:14dc": {
"*": {
"t_vendor": 4817,
"t_product": [ 5339, 5340 ],
"mode": "HuaweiNew",
"no_driver": true,
"msg": [ ]
}
}

But now when I run usbmode still get the error:

Failed to load config file

is there a way I can fix the usb mode somehow by getting the right usb-mode.json and config file?

Or if I can get my hands on an E3372 only not an E3372h-607/608 should that work since it doesn't need to switch the USB mode

here are my logs about it constantly trying to mount it as a CD-ROM

Usually when tinkering with configuration, I try to switch one at a time, then if it stops working I know what to switch back.

I guess the BIOS file is at least protected from corruption by a checksum?....

Anyways I'm not sure how it works, (though I wish I did so I can help ASUS crank out some revisions)...

Maybe an in place BIOS flash is in order, to get it back operational...

I just checked and the RT-AX88U got a new BIOS just recently on 3/29.  Did this happen after updating the BIOS to the latest?  Try reloading the previous BIOS if so...
