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.
I think I made small errors at each stage of this, typing the wrong name or picking the wrong file, and of course getting nothing or a bad file as a result. So I kept at it until I got it right.
First thing, of course, was to make sure bspatch was installed in a directory in the path, so that I could execute it from the directory where the patch and image files were located.
Because I knew I had messed up earlier, I redownloaded the patch file, just in case.
I unzipped the Nokia firmware image.
Then I opened a command window and navigated to the directory with the firmware and patch files.
I entered the command (I won't use the full file names since they're so long):
Note that there are 4 parts:
- bspatch
- the firmware image name ending in bin
- a name for the resulting patched image
- the patch file ending in bsdiff
If you're doing all that and don't get a result in under a minute, I don't know what's going wrong.
When I try to use the Windows .bin patcher, it keeps telling me "Wrong directory selected". I'ved tried numerous directories, moving the .bin file (only file in the directory) around, renaming directories, etc...
What's the difference in patching the image and flashing the 770 in Linux to enabled R&D mode? Is it just to be made easier for end users or is there an advantage?
