qFlipper Hangs at "[RCY] Co-processor Firmware Download @Acrudar START"

Just received my FZ, navigated to the download page and installed qFlipper. All went as anticipated until I reached the stage mentioned in the subject line. It has been (to all appearances) completely frozen for 20 minutes or more since reaching this stage.

Bottom two stanzas seem to repeat ad infinitum:

I’m loathe to disturb it for fear of bricking the unit. I’ve seen some references in these forums to recovery modes, but it’s not clear to me whether or not this is necessary yet… there are no indications of an error, but there is also no indication of success and the wait time seems… abnormal. I’m posting now in the hopes of shortening the time to until a productive response while I try to find and RTFM.

Cheers to anyone who can point me in the right direction.

Here’s a screenshot, in case it’s helpful:

I was able to resolve this issue myself, by reviewing the details here:

and by manually updating the driver (mid-update) – probably not an advisable path to success, but it worked for me:

  1. Load Device Manager
  2. Expand Universal Serial Bus devices
  3. Right-click DFU in FS Mode and select Properties
  4. Review Driver tab and see that the STM driver is loaded
  5. Choose Update Driver
  6. Choose Browse my computer for drivers
  7. Choose Let me pick from a list of available drivers on my computer
  8. Choose USB Easy Transfer Cable

Update resumed and completed with no errors.

Oh, I’m running Windows 11 Home, 21H2, build 22000.832

I confirm, the driver change worked
