I am glad to have tools to unpack the firmware. It lets us edit graphics and config files.

Seeing the number of engineers hanging out on these forums, I was wondering if FiiO would release the source of the X5 firmware code ?
I am sure that the community would be able to produce wonderful things and it wouldn't cost much to FiiO.

This is what I found on the same question for the X3 while reading the forum:

If it is the case for the X5 too,
I was wondering if it was just libraries being used or even parts of code in the core. 
 
If it is just libraries, they can be given in a static library (compiled) form, and we would never see their source code.
Then we could just work on the FiiO part of the code.

Does this make sense ?

Android is open source. I can't see why the X3/X5 firmware shouldn't be.

The idea of modularizing the code to separate what could be customized from what cannot seems logical.

right now I mainly want a more easily navigable user interface and maybe playlist support. I had wanted better support of the DAC but that does not look very likely.

As it turns out, the "system on a chip" that's being used for the X3 and X5, uses a certain architecture, closed source. And that's the core reason it can't be open sourced. FiiiO is contractually prohibited to do so (for now)

Interesting. I wonder if that also explains why Fiio is unable to modify the DAC input so that it can operate in a low power mode to allow us with iphones etc.
