I used a uno to attempt to burn the bootloader - I have done it successfully many times.
The Nano last night though refused to cooperate and I refuse to believe there is an electrical breakdown at ~ 1.5 - 2V that is why I am going for the fuse that got corrupted maybe it asks for an external clock now or similar shoot yourself in the foot issue.
But I dont know what fuses I should be looking at or how to unset or set as the case may be.
KeepIS I bought the programmer and header and used it for bootloader reinstatement but it had issues too.
I am 100% sure it was not a static damage issue I am too careful for that to happen.
I gave up and built another Nano to complete my tests with the rail supervisor.
