That should have been named:
update_contrast_0.2_install.bin
Did the PC you are using remove the ".bin" extension, or try to change the binary file into a text file?
This add-in is not packaged for your model of Kindle:
Code:
DX $ kindletool convert --info update_contrast_0.2_install.bin
Checking update package 'update_contrast_0.2_install.bin'.
Bundle FC02 (OTA [ota])

Optional 0
Padding Byte 0 (0x00)
That means that KindleTool was passed the option:
--device dxg
for the Kindle DX Graphite when the package was created.
If it is intended to work on all DX models (and I think that it is), then the option should have been:
--device kindledx
which is an alias for the dx, dxi & dxg models.
If you are brave enough to try it on your DXI, then just re-package the package (the KindleTool in NiLuJe's snapshots will take it apart and put it back together for you).
There are instructions posted here on how to do the re-package dance, search for them.
