I was really interested by your product, but there is too much thing I don't understand. I know that the UI is closed source and some kernel driver are also closed source. I'm ok with that. I also read that we can get the kernel source with DVD shipping, ok. But can we rebuild the kernel ? (even if we will have to keep close source module for the wifi for example). Can we then flash the device in order to use the custom-kernel ? It seems it's not the case, but I want to be sure Do you provide the toolchain ? (or maybe there is documentation for building the toolchain ourself) ? In your website, we can download the other half SDK, ok. But where can I download the SDK for building application ? Is it possible to build c program ? (if you give us a gcc toolchain, then of course, it should be possible. right ?) Do you have API to access to contact list for example ? Can we use python to access it ?

maybe I'm wrong and your product doesnt target geek guy ?

Look here and here. The first one is the github repo the kernel code gets pushed to (or was pushed to at a time, not sure about the current state) and the latter is the content of the DVD sent by Jolla on request, I assume it has been uploaded with a permission. it doesn't have the newest update though.

thank you, it nice to have the source. But how can we build the kernel ? Where is the crosstool ?

@freemanuu: Although I have not tested it, this: might lead you to the right direction. It looks like you have to get package / compile the toolchain for "armv7hl-hardfloat-linux-gnueabi"

ok, thank you. But I still cannot find the linux source. So I suppose we can only get them by DVD ? And I still don't know if we can rebuild the kernel.

Ok, I found the answer. They said, they are waiting to fix a tinkerability bug (source: ). it seems that this bug is still not fixed at the end of january ( So I suppose, we can buy the phone, and we will should get the ability to build the kernel later ?
