Firmware nightmare — gibberish (!) help needed


 

I attempted to update the firmware using my MacBook Pro. I followed the manual as follows:
?
  1. I navigated to the firmware menu choice and clicked "TUNE"
  2. Then I used a USB-C cable to connect to my Mac, and the drive appeared on my desktop no problem
  3. Then I copied the new file (yes, unzipped, named "1_01_003.QMX") to the drive
  4. It copied over no problem; and then it rebooted into screens that look like the screenshots below
I have a second QMX, but I'm too spooked to try it with that one now!
?
Has anyone ever seen this before? Is there a way out? I'd rather not have to open the radio (I bought it assembled). Help! :)
