I helping out my friend upgrade his 1.0.2 iPhone to 1.1.2.

Yesterday I'm stucked, I use installer and download virginize (3.x) from i.unlock.no.
The very moment download completed and run. I saw the process stop around ?????.commcentre and It prompt me error:'main script execution fails!' .

Any idea how to solve this? Been spending 12hrs since yesterday but no luck.
mine don't have such problem when virginize my 1.0.2 last week.
