Greetings
I have a C9300-48T stacked with C9300-24S. They had been running 17.03.05. After I upgraded using the following command
request platform software package install switch all file usbflash0-1:cat9k_iosxe.17.06.05.SPA.bin auto-copy
the stack now boots as follows:

and then it just sits there - never finishes booting, never goes into ROMMON or gives switch: prompt. I've tried
1. Repeatedly hitting Ctrl+Break during boot
2. Cold booting holding down mode button
3. Disconnecting stacking and power stack cables
all to no avail: the switch never finishes booting, nor does it go into ROMMON.
How can I fix this?
Thanks,

It looks like the ROMMON is corrupt.
Disconnect that switch from the stack (remove the stacking cables) and then force the switch to go into ROMMON.
Reconnect the power cord to the switch or the active switch. As soon as the System LED blinks, press and release the Mode button 2-3 times.
Once the switch is in ROMMON, use the "emergency-install usbflash0:IOS_file.bin" to put the firmware back in.

It sounds like it is "bricked" and will require an RMA. I would open a TAC case for this.
