Using vim is one way to do it and in case you are not familiar with
vi/vim you can use xxd on the command line to change your binary file
into text, edit the byte you want to change (since you know the byte
to be changed) and reconvert back to binary.
% xxd infile outfile_txt
edit the outfile using your favorite editor (assuming it will take the big file)
% xxd -r outfile_txt fixed_infile
That should do it too.
