sorry to answer late but You cant shortcut D+ and D- with +5V in any case! The method to shortcut it though 2 resistors its a way to force charging circuit to draw more power from wall charger than standard 500mA (up to 2100mA). Anyway, its special schematics where you connect D+ with D- and than connect it though resistor to positive 5V and to another resistor to ground. I dont have precise values of those resistors but on XDA theres a thread about speed charging.
I wonder if You managed to burn S2 charging controller - a followup would be fruitfull for us.
