connetion lost? hmm...then have u tried to update again? as in start from step 1? coz for my unit...i experienced the same thing as well...but then i restarted the updating process and the update manager ask me to remove the battery for recovery process which i ignore...then wait awhile say like 3 to 5minits then process will continue itself....its kinda bugging and problematic to update to version 20...previous versions were very easy to update...hope nokia can rectify this problem for future updates....
ITnooby,
U are reminded that asking for pirated stuffs in this forum are strictly prohibited...if mod sees this....he/she will delete ur post and might ban u as well....so becareful with what u asked for...

on the other hand, why dun use go and google for it? google is REALLY ur best friend u know....

u mean u cant even turn on ur phone..?

then u hv to try hard reset ur phone...hold green button, 3, * buttons at the same time and press power button on until you see the Nokia hands logo...if u success to turn on ur phone then later u try to backup ur content of ur phone memory n do a factory reset by keying #7780# at da standby screen..it needs to key in a security code...which default is 12345

..then i really hv no idea dy...i think da only thing to do is send in to da nokia care center...or u try to google arnd n c if there's any solution
