the basci idea is described here except that you don't write to the devices.

the files you get from there are 1 on 1 in the firmware. but they need to be packed to a format which can be read by the rsd lite flashing tool. some people can do such things (i love to hear how), but i can't ....
the other way is to do what is described in the thread above, but i wasn't success full. the main problem is that I wasn't able to reboot the phone. not simply turn is off and on again. this doesn't to it. some pieces like the startup image are read from the memory directly(used without reboot) but the kernel is not restarted when turning off and on.
perhabs someone have find a way to really reboot it ...
