hm, today i found out that wotanserver.com published video tutorials "how to flash sonny ericsson" with their flasher. Handy for begginer, I think, although nothing for pro :).
They covered a lot of models (C702, K800, W910,...). Anyway, the flashing process is allways the same, so it doesn't matter which model you choose.
videos can be found at YT: http://www.youtube.com/user/WotanServer
if you have seen another interesting tutorials about flashing/SE, share them in comments :)
