I don't like to flood, spam or write un-needed messages or else, but:
Up.
I'd like to have a satisfactory answer (thank you, Benson; I really appreciate you want to help, but there's not much I can do with that info). Again: Is there any risk in the 770 IT to get a WSOD reflashing? If the screen trouble did not affect me once, can it appear now? Also, if the unit is not under warranty, will Nokia replace it by a price?

I appreciate all help, thank you.
Saludos, Binky.
