ICX 7150-C12P Software Recovery times out when running the update commands to relaod images

[RustyPipes68]

I've got the dreaded "won't-come-back-up-following-a-power-outage" issue, where I've been following the instructions to recover the software via https://community.ruckuswireless.com/t5/RUCKUS-Support-for-Lennar-Homes/How-to-perform-a-Software-re...

All aspects of the connectivity are fine. I am able to set IP addresses, and connect in.

Where this all fails is when running the three "update" commands, i.e. "update_primary", "update_secondary" and "update_uboot"

Although I have successful  PING to my PC, when executing the updates, I see a series of "T" characters gradually spread across the screen, then I get a timeout message, with the suggestion that it is retrying, but immediately returns me to a command prompt.

I'm assuming therefore that the images are therefore corrupted?  Please advise.

Thank you.
