Good time of day.
Looks like I just bricol your router, installing the firmware it generation — I got a v3.5, but I rounded up to 4 and put the firmware for v4.
Now my router does not respond to pings, can't connect to it via TFTP, as advised in the wiki of dd-wrt
How else can you try to bring back to life my piece of metal?
Thanks in advance for your answers.
