Hi patel_nilesh_v
I don't know which version of Nokia Software Updater you are using but with v1.4.23en I either get "
update failed" just after it has downloaded 107.2Mb of software or immediately on "retry" for an N82.
If you are getting "
update cancelled" that points more to a network issue and would suggest that you try again another time.
Happy to have helped the forum in a small way from 2007-10
