Failed Software Upgrade SPS08030h to SPR08095g

[kvon12]

Hello, I tried to update the software on a ICX 7250-48 from sps08030h to spr08095g. The upgrade failed and now I'm getting the messages below. What can i do to recover the switch with a working image? Thanks

You need to go through 8080f if you are upgrading from that old of code. Try recovering to 8080f and then upgrading to 8080f and then to 8095:

setenv ipaddr <device IP address> - set ip address
setenv netmask <255.255.255.0> - set subnet mask
setenv serverip <xxx.xxx.xxx.xxx> - set tftp server address
setenv gatewayip <xxx.xxx.xxx.xxx> - set gateway address
printenv
- Try to ping your TFTP server.  If you cannot ping, check your connections. Once ping is successful, enter these commands:
setenv uboot spz10106.bin (change boot code image as needed)
setenv image_name sps08080f.bin (change OS image as needed)
saveenv
tftpboot

*load 8080f to flash via normal method and reboot

*then load 8095 via normal method and reboot one final time

Thank you. I will hopefully have time to try this later today.
