Hello @New2Cisco
You sure you follow this ?
Power cycle the switch. Immediatly press and hold the Mode button. Hold the button till the Status LED will go amber. Then on the console you should be in Boot Loader...
In that forum, Mode button does not function like this, so try also:
1.Reboot your C9300
2.Do not touch that Mode button now
3.Pay close attention to the console during boot. When the line "Last reset cause: SoftwareReload" appears, press the Mode button 3 times.
Best regards
