I remember when I broke our first ADSL USB (not RJ45 modem, the model was Netopia Cayman something). I was trying to port forward for NAT, but that damn thing had an old firmware that didn't have that feature. I was naive then, didn't quite understand what a firwmare was. So, I read on the official website that the new firmware version had port fortwarding. I downloaded the firmware and started the firmware update process through the web-interface. I waited 30min or so, I realized something was off, it should not take that much to flash a couple of mb. But stupid me, didn't know that unplugging the power cord while it was flashing was a bad idea. I was scared to death. Once broke, I didn't know where to look for informations to unbrick it. Spent 2 weeks with the ISP support center to get a replacement. Till today, I have anxiety when it comes to flashing firmwares.
