GS748Tv4 - Firware upgrade gone bad?

[bradcenter]

Hi All,
I have a the above switch where I upgraded the firmware from 5.0.2.18 to 5.0.2.28. According to the smart control center tasks, this was successful. I reboot the switch and cannot change the password or configure the switch. I reset to factory, tried change the password (default being password I assume) and it still won't let me change the password.

The switch now has a MAC of 00.00.00.00.00.01 and firmware is coming up as unknown. I tried reflashing to the old firmware, but it gives an error of "transfer timeout."

Weird - if I am in SCC and try a reboot - it asks for a password - put in password - and it reboots.

I put the switch on a completely different subnet than the default 192.168.0.238 that it is on - and it routes traffic just fine. I really just need this as a dumb gigabit switch - no vlans or anything - can I just use it as-is?

Or is there a solution to this?

Thanks,
Rob
