I see alot of posts (my own included) about various checksum errors during attempts to update Kindles.

What I find interesting is that it is almost never the same file.

My own experience has to do with a libtopaz.so file,

I installed a screensaver hack once but removed when I realized that I would have to uninstall / re-install if I wanted updates, anticipating folders I figured I could live without custom screensavers.

Now I could be wrong but I think my problem is a corrupted file that is not related to any hack, Amazon tech service has made vague promises about getting back to me but nothing so far.

Does anyone know how to replace a single system file on the Kindle?
(of course, one fear I have is that I get over the libtopaz hurdle only to be presented with another checksum errror.)
