I "managed" to brick my old Cisco 3640 : a friend of mine give me 2 flash simms from an old 3660. I've tried to boot mine with those two simms but it didn't boot : the system led is continuous flashing. I've tried back to boot it with the old simm (16MB) but the same behavior : the system led is flashing endless. If I connect the console cable to router it doesn't show anything. What should I try? is any hope to "unbrick" it? Thanks in advance.
Later edit : if I press any key into the terminal, I see a lot of strange characters, something like this :
When I saw that strange string, my first thought was : serial baundrate mismatch. I've checked and rechecked the serial settings, I even try with another serial2USB cable, I've changed the console cable. The only think that I didn't chanced was the laptop. With all this changes, nothing happened : same strange string (only when I hit a key on my keyboard). I've tried to boot up the router without flash simms : same behavior (nothing returns to terminal emulator just strange characters when I press a key). I will try to connect to the router using my desktop computer which has a serial port and see if something is changing. Thanks alot for your replay
