After trying to downgrade a Nexus 7K from 5.2.1 to 5.1.5 by updating the boot & kickstart boot statements and reloading, I'm now stuck in an endless cycle of reloading. See below:
Is there a break sequence which will allow me to modify the boot statement back to the original via ROMMON or something similar?
This is what I'm getting on the terminal at the moment:
INIT: version 2 Checking all filesystems...... done. WARNING! WARNING! WARNING! ************* This kickstart image is not compatible with * the current hardware platform * Rebooting system * WARNING! WARNING! WARNING! *************

Do you see any checks failing within all the logs you see on screen? In some case that ended up as SUp HW fault. Possibly worth trying to reaset SUP within slot and boot again. May get different result.
Also you can opene priority TAC case for engineer to check this online.
The above cmd will get you going back to the older/working version.
If you run into this problem and need further assist, kindly provide the basic sh cmds (sh ver, sh inv, sh mod, sh run etc) while running the older ver along with the console log when you see the problem.
Also include the precise cmds typed to change the boot statement, save the config and include the output of sh boot
I can confirm that the ctrl+c break command does the trick. However, I think in future I will pay heed to our Cisco rep and only use the ISSU feature to upgrade/downgrade to different versions of software. This way, you should never end up at this point.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
