Let me clarify the things: the dump I got was from a RDA device and only some contents are readable remotely -- and I already include all I could get remotely in the system dump from OP. It was useful at the time I opened this thread since no firmware were available at the moment and the hype around Nokia X was veeery high. Now, you can simply use Nokia Care Suite or NaviFirm+ to get a full firmware dump (there are instructions on how to do this in the Nokia X forum section). That said, I don't have a Nokia X and I won't update this anymore -- Make good use of what's included or get the firmware yourself if you want something that's missing from this dump, no more questions (or PMs) about it, thanks...
