Kindle syncing firmware is closed source. Changing the syncing firmware would require decompiling obfuscated java and changing it.

There are several known "fixes".

1. Don't muck with CDETYPE.
The problem with the first fix is that Calibre sets the CDETYPE automatically to EBOK when converting to AZW3. Kovid has refused to change this behavior. Most folks who are not regular MR visitors have no idea that the CDETYPE of their sideloaded books has been changed by converting them to AZW3.
