imageCLASS D570 stuck in DOWNLOAD MODE after UPDATE AND DOWNLOAD MODE first appeared.

[RG2]

After rebooting a few times, I'm writing because my one year old (formerly fully operational via WIFI and USB) D570 printer boots directly to UPDATE and DOWNLOAD MODE (this may take awhile); then next comes DOWNLOAD MODE with an apparently temporary (non-operational)  IP Address on the screen that doesn't match the WIFI or Computer previously associated with the printer and then doesn't do anything. It is frozen there until I de-power the printer. I've attempted to download a Cannon Support FIRMWARE UPDATE (Mac-mf240-230-D570-fw-v2211) but it doesn't open, thus I can not provide the download to the printer.  It is stuck.  I'm using an Apple M-4, Tahoe 26.3

Greetings,

Have you tried the following: 

Turn the printer off and unplug from its AC outlet.

Press and hold the power button for 15 sec.

Wait 60 sec.  

Reconnect to power. 

Press and hold the Stop button.  While holding the stop button, press the power button to turn the device on.  Continue to hold the stop button until the printer has booted, fully restarted.  Now release.  Result?
