Well, this comment is a little premature, because I have downloaded the patch, applied it and then installed the patched version on my 770.

But I did that just 15 minutes ago, and I haven't used things yet.

I wanted to add a little more information for any Windows users who would do this.

The program you need to download, as KreAture noted is at sites.inka.de/tesla/f_others.html#bsdiff

What I should have done, but didn't initially, was go to the real home page of the program, at www.daemonology.net/bsdiff/ where a brief description of the utilities can be found. When you unpack/install it, you have two utilities, not one.

bsdiff is the program that KreAture used to create his patch. bspatch is the program we users use. I thought I was supposed to use bsdiff (because the patch file has that as an extension), until I read the description.

And the first time around, I wasn't paying attention and what I did was run the patch on the zip file of the image that I had downloaded. That doesn't work. So, be sure to unzip the binary image and use bspatch to apply the patch to the file with the .bin extension. And of course you run bspatch from a command prompt window.

Typing simply "bspatch" on the command line gives you the usage the program expects, btw. And if the patched file isn't created within a short period of time -- 20 seconds? 30? In my case, well under a minute -- something isn't right.
