@Mentalist Traceur;
i do it with the flasher. but iam curious:
the sync: does it work with the nand? or do you sync for something else i am missing. [to be clear: with flashing i assume the stuff is written to the nand and i think thats what the flasher is for. and sync actually does the same thing(force writing to medium in general not nand). see my questionmarks? ]

besides: i see you flash. and i wonder does the tool somehow ensure the flashed kernel is used? i am used to either have to kexec or reboot for a kernelupdate to be complete. how does it work without that(technically) or am i missing something?.
