As I told, the update won't do a full replacement of the installed firmware. There is _no_ update package that would restore each and every file, so you can brick your existing file system beyond repair (you might have done so, it's hard to tell).

I can't really see what launchpad would be breaking, so my guess is on the chinese input method. Do you have a pointer to a thread where you get instructions and software to install?

Maybe you're able to get USB networking installed and running (for which you'll probably have to configure it to autostart) and can better explore the "real" filesystem. But always make sure you know what you're doing.

Edit: arrgh, I forgot that you probably will not be able to install USB networking files. I think your back door might be launchpad, if it's working. Did you try if launchpad combinations work? Another option is the serial console. And the most prominent option is probably to send it in to Amazon....
