WF-7720 Firmware Downgrade Not Working

Recommended Posts

i cannot downgrade my WF-7720 [FA27K7] to version [FA27HC] in NORMAL MODE:
i did my best on the manual but the printer does not restart [i wait 2 hours, hangs up]
i unplugged the cable and after 5 minutes plugged in: => starting Recovery Mode
i have reinstalled the firmware FA27K7 with "wicreset recovery firmware" in recovery mode <= this works

in RECOVERY MODE:
i receive an error message: ROM IS NOT WRITABLE

the same for me, the update does not take place in normal mode, I have to restart the machine so it goes into recovery mode. the problem is that in this mode it puts "rom no reritable"
