Why do people come on here and ask for help and then don't do what is suggested?What does the continuous ping accomplish in this instance?
You need to read the downgrader thread, the entire thread. It's clear you haven't.
Sounds like you have not read the tftp updater instructions ...
For 2 or 3 seconds after power-on, then nothing - shows it's likely to be in the classic boot loop. It responds at 188.8.131.52 while it's set up to probe for the updater tool.I'll have to try it when I get home, but if I get ping responses, what does that mean?
You are correct that the serial console can be used to recover from bad things like firmware corruption etc - but this hasn't reached that stage, it's responding fine to the tftp updater.Like I said in another post, the solution is to use the 4 points connector with a small interface (like jtag), to unbrick, place new firmware and so on.
