what is it
this tool is named "0xFFFF"
it is used for flashing ,dumping and managing firmwire of nokia n900 like phones,
there is a official tool named ,meaemo_flasher from nokia but it is highlevel tool,
and this tool is low level tool.
as far as i know nokia's flasher tool cannot dump memory of device but this tool can.
update:
Note
this tool provides cli option for dumping but it is not working when tested.
it says that device dumping only possible when connected by storage mode,
