But *118*3*1*# works on my Mozart with WP7.5.

I haven't try with Mozart WP7.8 yet. I guess it'll work too.

Oh by the way, I've managed to update my Mozart to 7.8.

Very hard to update.

The correct way is what everyone have been saying last few pages.

Time it. If it takes 10s to show no update, you have to disconnect WiFi at 9s.

However, my PC take random time to show no update. That's why I take whole night to do 3 update.

And final update I can do it this morning.

I thought need 1 update.

But it need 4 update.

Not sure why certain phone behave certain ways. LOL

Yes. Phone quite hot when downloading game. Playing game also hot.
