The installation seemed fine and everything went as stated in the guide, but after having installed the firmware in mtdblock1 and mtdblock2, I rebooted my router and the web interface doesn't work. I can't connect to 192.168.1.1 anymore, even with telnet. The guide stated that I should have openwrt webinterface after the reboot. Did I miss something? I did the backup on the usb external drive, but without telnet working I can't even restore it.
Which firmware did you use? The Chaos Calmer is pretty old and it would be better to try a newer version.
Also telnet is deprecated, so can you try with SSH instead?
Does ping work?
I used the chaos chalmer since is the latest .image file (and not squashfs .bin file). The guide updated the firmware after the chaos chalmer firmware upload, so I think this is the way. However, ping doesn't work, seems the router doesn't have an IP. I'm pretty sure it's bricked, but I wonder how I can use the backup I made into the usb drive to restore it
My guess is to follow the opposite direction of the commands you used to make the backup.
Do you have a serial interface cable to connect to the router?
I do, I only need some wires to solder which I don't have at the moment. I don't know how to use the mtd0~mtd6 backups using the serial connection though.
I finally managed to use some cables and connect through the serial port, installed openwrt using the standard procedure and now it works. Maybe the webinterface method is not very reliable
