zenutils is a collection of utilities for working with firmwares of the Creative Zen range.
|
|
|
|
The utilities are split into 3 categories:
|
|
1) update_*
|
|
Operates on the Creative firmware updater executable.
|
|
2) firmware_*
|
|
Operates on the Creative firmware archive.
|
|
3) zen_crypt
|
|
Operates on the parts of the firmware archive which requires cryptography.
|
|
|
|
|
|
General usage:
|
|
--------------
|
|
A typical use scenario would be: download the firmware updater and run
|
|
update_extract on it to obtain the firmware archive which it contains.
|
|
Run firmware_extract on the firmware archive to obtain the files
|
|
which the firmware archive contains and a make file that can later be used
|
|
to create a new firmware archive. Edit* the extracted files of
|
|
interest and optionally the associated make file. Create a new firmware
|
|
archive by running firmware_make. If a NULL entry is present in the firmware
|
|
then it's signature has to be updated running zen_crypt. If on windows, you
|
|
can use update_patch to write your newly created firmware archive to the
|
|
updater executable which you originally extracted it from. The new updater
|
|
will update your player with the modifications you've made.
|
|
|
|
* If you're creating or editing executable code, such as the CENC or ©TL entries,
|
|
you'll need to use zen_crypt to decrypt and/or encrypt them.
|
|
In addition, executable code on some players that use the ©TL entries also needs
|
|
to be signed using zen_crypt, prior to encrypting them.
|
|
Encrypting FBOOT and FRESC is not supported, as these contain the executable
|
|
code that makes up the critical Rescue Mode software, contained in flash.
|
|
As opposed to CENC and ©TL which ultimately ends up being stored in the players
|
|
filesystem as a file named Jukebox2.jrm.
|
|
|
|
|
|
Important:
|
|
----------
|
|
The only entries required in a firmware archive is CINF and if present, NULL.
|
|
Including either FBOOT, FRESC or EXT0 in your firmware archive is not advised,
|
|
the first two are required for the Rescue Mode software operation and EXT0 is
|
|
unknown, but given that it's contents is sent to an internal device named mcu0,
|
|
the consequences of failure could be fatal to your player.
|
|
|
|
|
|
Supported players:
|
|
------------------
|
|
zen_crypt supports signing, verification, decryption and encryption on the
|
|
following Creative Zen players:
|
|
Vision:M (default if no player is specified)
|
|
Vision W
|
|
Micro
|
|
MicroPhoto
|
|
Sleek
|
|
SleekPhoto
|
|
Touch
|
|
Xtra
|
|
|
|
The other utilities are not player specific and may work on players not listed.
|
|
Although the Vision:M is the only player I've fully tested.
|
|
|
|
|
|
Building the sources:
|
|
---------------------
|
|
The source code uses the CMake (www.cmake.org) build system.
|
|
Once you've installed CMake, you'll need to run it to produce make files for
|
|
your system. I would recommend producing the make files within in the 'build'
|
|
directory of this package. Which can be done by typing:
|
|
zenutils\build\>cmake -g "Visual Studio 8 2005" ..
|
|
(for msvc8 on windows)
|
|
or:
|
|
~zenutils/build/$ cmake -g "Unix Makefiles" ..
|
|
(for various 'nixes)
|
|
The windows example will produce a solution file for msvc8.
|
|
The 'nix example will produce a makefile which can be built using make.
|
|
|
|
The executables will be placed within the 'bin' directory, once built.
