Hello -
I appear to have similar issues that an earlier poster highlighted via below:
https://community.ruckuswireless.com/t5/RUCKUS-Support-for-Lennar-Homes/ICX7150-switch-boot-mode/m-p/79027
When I reset, the CLI displays:
"Bad FTT kernel image format!
ERROR: Can't get kernal image!"
I have tried following the software recovery steps at below link, using latest ICX-7150 Stability Release (RUCKUS ICX FastIron 08.0.95n (GA) Software Release (.zip) using ttftp64 to load the SPS08095nufi.bin file via PuTTY CLI, but appear to get errors when i use "update_primary" and "update_secondary" commands. Note that I have confirmed that my ping to 192.168.0.2 is alive, so connection should be OK. The firmware download file for the Stability release included "Images" files but did not include "Boot" files as mentioned in the below walkthrough...
