Error during update 3.0-3.4

I was updating from 3.0 to 3.4 when I got an error about one of the files not working or unable to load. Now my radio is stuck on a loop asking for the usb to be put in. I have downloaded the file several times and put onto my usb but I get the same error. Now my radio is stuck and I can’t even access it since the screen is looped to asking for a usb.

Nevermind I fixed it!
