(3) Observe minimal log details and message "See the debug log on VT3 for the full output".
(4) Press CTRL+ALT+Refresh (F3) while recovery is still ongoing.
(5) Observe, nothing happens. Screen is not changed
(6) Once recovery finishes and prompts for USB removal to reboot, press CTRL+ALT+Refresh
(7) Observe VT3 output is shown.

Expected Result:
VT3 debug output should be viewable during recovery process (step 4 and 5)

Actual Result:
It's impossible to switch to VT3 while the recovery is ongoing.
