kindle firmware update weirdities and oddnesses
Just 12 days ago I downloaded all available kindle firmware updates for all eink kindle models.
I discovered that a couple of the update*.bin files were slightly different sizes than files I had previously downloaded awhile ago. I extracted and compared the contents of these update files. The ONLY difference was that a different method of updating the java certificates was used.
Previously, the (text file) certs were patched with a huge monolithic script that ran "bspatch" on a ton of binary patch files that patched both binary and text files.
In the latest download of the latest update files WITH THE EXACT SAME FILENAME as the older versions, the certs update patch files were removed, and the huge monolithic script has had the cert patching code snippet removed. Instead, there is a new (complete) cert file, and a new script to replace the old cert file.
Today, I downloaded a bunch of update*.bin files for multiple of my kindle models, and comparing them shows that the file sizes have also changed on those files, even though the download file names are exactly the same as the previous different downloads of these same file names.
Kindle does not mention anything about multiple different versions of firmware update files with identical file names, nor any need to update your kindle. I wonder how this will affect folks (such as myself) who have already installed the old versions of the latest firmware files on some of their kindles...
